Klaus Busse is the talented head of design for Alfa Romeo, Fiat and Chrysler, and he is also quite active on social media. We read today a post from his hand on his Instagram page about the presentation of the Tonale at the Geneva Show two years ago, together with some stunning photos showing how the Tonale was sculpted out of plaster and other materials to become a real looking car, to be shown as a styling model at the salon.
The photos show how elements of the car were formed and made by hand. Some pieces were 3D printed, I believe, but personally I find it truly amazing how these craftsmen put the car together, and finished it to become a design model with gleaming paint and shiny elements, the result being indistinguishable from a “real” car.
I found the photos so interesting that I want to show them here to you on these pages.
On the fourth of May 2019, I visited the Centro Style in Turin, and met Klaus Busse. You see me standing proudly beside the Tonale prototype, and also in a group photo with Klaus Busse himself on the left.
Sweet memories, and of course your servant would love to witness once how these craftsmen work to create such an unbelievably finished prototype…
Dynamic Stellantis PR Manager Dominique Fontignies sent us yesterday his photo of the Fiat Centoventi concept displayed at the “e-Village” in the Green Pea building in Torino.
What is this e-Village? It is a branch of Mirafiori Motor Village in Turin and it’s the biggest sales point of electrified cars in Europe.
It’s located in an area of 1300 square meters inside Green Pea and showcases all FCA technologies related to electrification, including hybrid and all-electric vehicles on the market, as well as prototypes of upcoming models.
It’s a zero-impact space that adopts the “reuse, reduce, recycle” philosophy and it can be considered the fulfillment of the efforts made by FCA to promote the future of mobility.
At Floor 0 – move, energy & connect, inside the e-Village: the space entirely dedicated to the sustainable future of mobility wanted by Stellantis, the fourth automotive group in the world.
In e-Village halls you can find all solutions of the Group’s for the avant-garde mobility, such as the Electric New 500, Panda Mild Hybrid and Jeep and Ducato’s electric vehicle range.
This breathtaking journey, narrated by Olivier François – President, Fiat Brand Global and FCA Chief Marketing Officer, includes interviews with designers, tales of partners, close-ups on the details and selection of materials, where the aim is caring of the environment and its sustainability.
The short film (15 and a half minutes) presents a relentless succession of meetings and processes that highlight teamwork, the affinity between designers from different fields and the emotions involved in playing an active role in an extraordinary project: the creation of something unique, an interpretation of the New 500 alongside the very best of “Made in Italy”.
The result is the three One-Offs, embodiment’s of the style, creativity and craftsmanship characteristic of “Made in Italy” and of our partners in the project, in the path and in the vision of the Earth’s future.
The journey depicted in the film begins in Turin, cradle of the Fiat brand, passing from Rome on the way with its sunsets, colors and lines that symbolize Bvlgari all over the world, to arrive in Milan, the world capital of fashion and design, due in no small part to Armani and Kartell.
The twist in the tale has Milan as the setting for the entire presentation of the New 500.
A veritable gearshift takes place in the film’s account of the tense time when the Geneva International Motor Show was canceled, and a plan B had to be found and set in motion. The presentation of the New 500 and the One-Offs was completely rewritten to pull up stakes, to Milan.
The short film is created and produced by VICE Italy, with Rockets at the helm. It uses the language of documentaries to reveal aspects normally concealed from the general public, in an immediate and effective way.
In an authentic, realistic vernacular, the evocative film opens the doors of the Style Center in Turin to the cameras. We get an exclusive peek inside the “Color & Material” department led by Rossella Guasco, halfway between a sophisticated research center and an elegant fashion atelier.
The footage documents their almost-obsessive attentiveness to every detail, that “know-how” typical of Italian creativity, and dwells on the emotions of the whole team as they experience something truly unique.
The journey continues in an interview with Klaus Busse, Head of Design, explaining what lies beneath the creative process of style and forms, and the role of the 500 in the history of industrial design, even more so in the collective unconscious.
It was the Style Center that took a legend of the 50’s, the fabled “Cinquino”, and reinvented it in 2007 to “color” everyday life and streets all over the world, making it an authentic, unique and salient response to the requirements of international urban mobility.
At the Milan launch of the One-Offs in March, it was even announced that the Fiat 500 has been confirmed as an “Italian Icon and Honorary Member” of Altagamma, the prestigious Foundation that brings together the best of Italy’s companies, to promote the epitomes of the country’s excellence around the world.
Just have a look at the photos here, and also enjoy the film!
Electric vehicles have progressed with leaps and bounds over the last few years. Developments in battery technology have helped massively to make E-vehicles now a practical proposition. But this doesn’t mean that our European car manufacturers didn’t focus on it since decades…
Mercedes is of course no exception. They had a fully fledged, 100 % electrified 190 sedan running around on the German Baltic Coast island of Rüge. Recharged with sustainable wind power. Fully practical. One of the fleet of 10 cars even functioned as a taxi and clocked not less than 100.000 kilometers in one short year. All this almost 3 decades ago…
Just read on!
Hans Knol ten Bensel
One such story is set in 1990: in May of that year, Mercedes-Benz exhibited a model 190 (W 201) converted to electric drive in the innovation market section at the Hanover Fair.
A (literally) very hot car…
The electric 190s were used to test different drive configurations and battery systems. The energy storage devices tested were mainly sodium-nickel chloride or sodium-sulphur high-energy batteries which had a significantly higher energy density than classic lead batteries.
However, the working temperature of both systems was around 300 degrees Celsius. The group expressing the greatest interest at this industrial fair were representatives of the trades.
Further development went fast…
There was a considerable shift in this just under a year later, when, in March 1991, Mercedes-Benz displayed a more advanced vehicle on the Geneva Motor Show.
Each of the rear wheels of the vehicle presented in Geneva was powered by its own DC motor energized by permanent magnets with a peak power of 16 kW (22 hp) each, so the total power output was 32 kW (44 hp).
Energy was supplied by a sodium-nickel chloride battery, and regenerative braking returned energy to the power pack during braking actions.
A particular advantage of the concept was the elimination of weight-intensive mechanical components, so the additional weight compared to a series-production vehicle with a combustion engine was only 200 kilograms.
The issue of electric cars experienced an upswing at that time as a result of the laws passed in California, for example, to introduce zero emission vehicles.
This led the German government to fund a project to the tune of 60 M DM (now some 30 M Euros), and this led to several manufacturers, including Mercedes-Benz, to participate in a large scale field trial was conducted on the island of Rügen in 1992 and continued through to 1996.
The aim of the exercise was to test electric vehicles and energy systems including their batteries in everyday practice. A total of 60 passenger cars and vans of several brands were involved.
Among other things, Mercedes-Benz sent ten W 201 model series saloon cars, which had previously been fitted by hand with drive components in various electric motor-and-battery combinations in Sindelfingen, to Rügen. Special recharging stations using solar collectors were available during the field test with a view to testing the environmental concept in a consistent manner because only electricity from renewable sources can be considered completely CO2 neutral.
100,000 kilometres in one year with an electric test vehicle
The pioneering 190s were driven by test participants on the island of Rügen: these various individuals, including taxi drivers, used them in normal everyday life. There were hardly any problems – the W 201 cars went about their work completely inconspicuously and reliably. One of the vehicles was used particularly intensively and achieved a peak usage rate of around 100,000 kilometres in one year.
Why did it take so long to adopt E-power for the masses?
The obvious question is why we waited so long to put E-powered cars into practice in larger numbers?
The problems then – and now – were: battery service life, range, recycling, charging infrastructure and vehicle price. Many of the answers to these questions have only become available today, as can be seen by the range of hybrid vehicles offered by Mercedes-Benz and, of course, the EQ electric brand. Projects like the 190 with the electric drive have helped to provide these answers…and it is very interesting to look into them here once again!
The futuristic car on the photo here embodies Renault’s vision of personal, shareable electric mobility in the years beyond 2025. It’s called the MORPHOZ.
It draws on the Alliance’s new modular CMF-EV electric platform to offer several configurations not only of power, capacity and range, but also of user options and boot space too.
Faithful to the brand’s DNA, the MORPHOZ concept embodies the Family petal of Renault’s ‘Life Flower’ design strategy, which is based around the stages within a person’s life.
However, it is not only just a vision of mobility. In its design, details and interior presentation, this MORPHOZ also heralds a new family of Renault electric models for the coming years.
The Renault MORPHOZ uses a brand new 100% electric modular platform
that we call CMF-EV.
Like the CMF-B platform which was inaugurated last year by the Clio and used on the New Captur, CMF-EV has been developed by the Alliance. It allows us to design, build, adjust and fine-tune electric vehicles more easily than with a platform designed for internal combustion engines (ICE) or for mixed ICE/electric applications.
The platform’s architecture allows a long wheelbase with wheels at the very corners of the vehicle, reduced overhangs and a flat floor. With a streamlined battery, the CMF-EV platform allows to design vehicles that are closer to the ground, with a lower roof and the all-important improvement in aerodynamic performance. The low centre of gravity is also a bonus thanks to the location of the batteries below the rear floor.
MORPHOZ, a personal vehicle that can be tailored to requirements
Renault MORPHOZ is a 100% electric adaptable crossover concept car which charges by induction even as it is being driven.
It is connected and equipped with level 3 autonomous driving functions. Like the SYMBIOZ concept unveiled in 2017, this is a personal vehicle which now boasts specific sharing functions.
The high adaptability of the MORPHOZ concept-car is demonstrated by the physical transformation that occurs between its two versions: the short “City” one and the long “Travel” one.
The vehicle is in fact capable of adapting itself to the way its users live, be it for daily use or, for example, holiday travel. To achieve this, the City version is fitted with just the right battery capacity to meet day-today requirements, while the Travel version can accommodate the extra capacity needed for long distances on motorways, for example.
Although it is very slender in the City version, the vertical section of the front wing on the MORPHOZ expands in the Travel version as the vehicle’s bodywork and wheelbase lengthen.
Although its primary role is to display the capacity meter of the onboard batteries, its black and yellow finish also makes it stand out from the rest of the bodywork.
The City version
The short City version of the Renault MORPHOZ is 4.40 metres long. At 2.73 metres, its wheelbase is a record for such a vehicle length,so that it can easily house the 40 kWh of batteries that are fitted as standard.
The long Travel version of the Renault MORPHOZ is 4.80 metres long. Its wheelbase is proportionately longer at 2.93 metres to allow it to accommodate the additional battery capacity and provide a spacious interior. It can thus carry extra batteries that provide 50 kWh of power (total capacity of 90 kWh) and offer more leg room for the passengers, along with enough space for two more suitcases. In addition, this version – which benefits from a specific light identity – has a specific tapered
front-end and profile to improve its aerodynamic performance for long distances.
A very clever car, brimming with further smart solutions for its passengers, more about this in a next report…
We are living in digital times. So even when the Corona virus limits (temporarily, as we all hope) our present mobility, and led to the cancellation of the Geneva Motor Show, we can still see all the automotive news via our PC’s, Phones, Tablets.
Ralf Brandstätter, Chief Operating Officer of the Volkswagen Brand, presents here the ID. CROZZ showcar, which now evolves into its series production version, the ID.4.
Volkswagen is forging ahead with its electric mobility strategy by providing a detailed insight into the brand’s first all-electric SUV. The new ID.4 will be launched this year. Following in the tracks of the ID.3, the countdown has already begun for the second model based on the new modular electric drive matrix (MEB). “Just like the ID.3, the ID.4 will also come onto the market as a carbon-neutral vehicle”, explains Ralf Brandstätter, Chief Operating Officer of the Volkswagen brand. “We will produce and sell the ID.4 in Europe, China and the U.S..”
Just read on for more VW news…
Hans Knol ten Bensel
The ID.4 will initially be launched with rear-wheel drive, while an electric all-wheel drive version will be added to the portfolio at a later date. The high-voltage battery is positioned near the center of the underbody to create a low centre of gravity and an optimum in terms of driving dynamics, along with an extremely well-balanced axle load distribution.
Also new mild and plug-in hybrid drives…
For Volkswagen, the ID.4 and ID.3 represent important milestones in the brand’s bid to become entirely carbon-neutral by 2050 – in line with the Paris climate agreement. Plans have been put in place to reduce the Volkswagen fleet’s CO2-emissions by a third by as early as 2025.
Volkswagen is currently investing one billion euro to electrify its model range while also offering an increasing number of hybrid vehicles. This is based on the fact that, just like electric powertrains, new mild and plug-in hybrid drives in large-scale product lines such as the all-conquering Golf will significantly help to reduce fleet emissions in the future.
New Touareg R
This is why the company’s focus during the webcast is not only on ID. models, but also on new Volkswagen models with hybrid drive. Dr. Frank Welsch, Member of the Board of Management of the Volkswagen Passenger Cars Brand with responsibility for Technical Development, presents in the webcast the new Touareg R with plug-in hybrid technology and the the Golf GTE 2 for the very first time.
The Touareg R,the most powerful Volkswagen model will in future also be powered by an efficient plug-in hybrid system. The alliance between an electric drive motor generating 100 kW (136 PS) and a V6 turbocharged petrol engine (TSI) with an output of 250 kW (340 PS) develops a system output of 340 kW (462 PS). The battery capacity of the Touareg R with a top speed of 140 km/h in all-electric E-MODE has been designed so that most average daily commuting distances can be covered with zero emissions.
Golf GTE with stronger battery…
The same applies to the new Golf GTE – its plug-in hybrid drive has been geared towards performance and consists of an electric drive motor with 85 kW (115 PS) and a four-cylinder turbocharged petrol engine (TSI) generating 110 kW (150 PS). As a unit, the electric drive motor and the TSI develop a system output of 180 kW (245 PS). The new Golf GTE’s top speed in all-electric mode is 130 km/h.
Further Volkswagen highlights include the new Golf GTD, which generates significantly lower nitrogen oxide emissions compared with its predecessor thanks to innovative twin dosing technology, plus the eighth generation of the Golf GTI, produced more than 2.3 million times. The most recent version is powered by a 180 kW (245 PS) 2.0-litre turbocharged direct injection engine. The maximum torque is 370 Nm. The four-cylinder engine is coupled with a 6-speed manual gearbox as standard.
Last but not least, the eight generation of the GTI takes the central stage, presented again by Ralf Brandstätter, Chief Operating Officer of the Volkswagen brand. It is a formidable performer, this GTI, and A 7-speed dual clutch gearbox (DSG) is optionally available.
We include here some screenshots of the webcast, and stay tuned for more!
The Brussels motor show is always a unique event. Last but not least because this is a true buyers’ show, to be taken in the literary sense: about 30 % of the annual car sales in our country is done on the grounds of the Motor Show!
“Our” show is also unique because all the brands are present here in Brussels. First of all because no car manufacturer wants to miss the sales opportunity, but also because the Brussels show is also an ideal “test” market, it allows brands to assess what global (European) market share they can achieve overall and for their respective models individually, judging by their penetration in the Belgian market, where no national brands can distort the situation in our market place.
We took a walk through some of the stands, and here follows our report, where we focus on the brands we did not yet discuss already in our show preview, starting here with BMW.
Hans Knol ten Bensel
BMW and MINI unveiled two world premieres with respectively the BMW plug in hybrid versions for the X1 and the X2 models, the BMW X1 xDrive25e and the new BMW X2 xDrive25e. BMW is pushing its electrification very hard forward, and on the accompanying photo you can see the table they displayed at the show, showing the further steps they are taking towards an electrified future. An electric drive and a lithium-ion battery enable an electrically powered range of up to 57 kilometres in the two new plug-in hybrid models. In the near future, four BMW X models with plug-in hybrid drive will be available. BMW intends to have more than one million vehicles with electrified drive on the road by the end of 2021.
The plug-in hybrid system of the new BMW X1 xDrive 25e and the new BMW X2 xDrive25e consists of a 1.5 litre 3-cylinder petrol engine with BMW TwinPower Turbo Technology and an electric drive specially developed for this model. It is taken from the eDrive technology modular system of the BMW Group. The petrol engine mobilizes a peak output of 92 kW/125 hp and a maximum torque of 220 Newton meters. It transfers its power to a 6-speed Steptronic transmission and drives the front wheels.
The electric motor generates an output of 70 kW/95 hp and delivers 165 Nm of torque to the rear wheels via a single-speed transmission. This makes for a hybrid specific all-wheel drive…Together the combustion engine and electric motor produce a system output of 162 kW/220 hp. The maximum system torque of both drive units is 385 Nm. The new BMW X1 xDrive25e accelerates from 0 to 100 km/h in 6.9 seconds. The new BMW X2 xDrive25e does the 0 to 100 km/h sprint in 6.8 seconds. The top speed of the new BMW X1 xDrive25e is 193 km/h. Maximum speed of the new BMW X2 xDrive25e is 195 km/h.
The MINI crowd was also spoiled with a world first of a Sidewalk Edition of the MINI convertible. The MINI is already cute, desirable and truly iconic, and a cabrio version adds to all the pleasure a MINI can offer its driver and occupants. Variants of the exterior paintwork, soft top design, rim styling and interior fittings are developed especially for the edition model. The version of the fully automatic textile soft top, specially designed for the edition model, can be opened or closed electrically and almost silently in 18 seconds. It features an artistically woven-in arrow graphic in the particularly high-quality finish typical of MINI Yours. The 17 inch light-alloy Scissor Spoke 2-tone wheels of the new MINI Convertible Sidewalk are also a model-specific design feature. There are also the side indicator bezels, known as side scuttles, which bear the “Sidewalk” model designation.
Three engine versions are available, The new MINI One Convertible Sidewalk develops 75 kW/102 hp from the 1.5 litre 3-cylinder engine. The new MINI Cooper Convertible Sidewalk is also powered by a 1.5 litre 3-cylinder engine which produces 100 kW/136 hp. The 141 kW/192 hp 4-cylinder engine of the new MINI Cooper S Convertible Sidewalk provides the sportiest fresh air experience.
European premieres for BMW and MINI
There were also European firsts in Brussels, like the BMW 2 Series Gran Coupé, interesting as it is beautiful, and we are certainly keen to drive one soon to tell you more about it. The same goes for the BMW M8 Competition Gran Coupe. It has a 200 mm longer wheelbase makes extra room for the rear passengers.
Furthermore there is the insipring MINI John Cooper Works GP, with a 4 cylinder 306 HP engine, catapulting this Mini from 0 to 100 km in merely 5,2 seconds. It is produced in Oxford in 3000 units, and is on sale from March 2020.
The BMW BMW X5 M and X6 M have their Belgian premières, the 4,4 litre V8 is good for 625 hp and this formidable engine makes these cars sprint form 0 to 100 in merely 3,8 seconds. Last but not least there is the Belgian first of the MINI electric, or the 3-door MINI Cooper SE.
On the stand, we stood also eye to eye with the BMW Vision iNEXT, the optical highlight of the exhibition stand, which also showcases the interior design principle “My Favorite Space” with harmonious, natural surfaces and technology that is kept discreetly out of sight.
Just look at the photos here… which answers the question: “What will cars look like when they no longer have to be driven by a person, but still can be?” The interior can be a place for relaxation, interaction, entertainment, or concentration, as preferred. It is more like a comfortable and fashionably furnished “living space” on wheels – a new “Favorite Space”. A new design principle, referred to as “Shy Tech”, plays an especially important part in this.
To preserve the high-end, yet cozy character of the rear compartment, and place its occupants center-stage, the intelligent technology behind the operating controls is integrated out of sight. It only becomes visible and operable when required by the driver or passengers…
Soon more about other brands and novelties we saw on the Brussels show…
Faithful readers will remember that we stood in the FCA Centro Stile eye to eye with the stunning design concept car, the Alfa Romeo Tonale. For those lucky ones who will be invited to the gala evening and attend the press day on January 9, we have good news : it will be on show on that day in the Hall 7 of the Brussels Salon…
Hans Knol ten Bensel
Indeed, you can admire it for one day in Hall 7 of the Motor Show buildings, and you will see its design language close up. This is rather important, as its shapes will be seen back in the second SUV which will bear the Alfa Romeo badge.
Its expressive design and compact shape bode well for the future styling of Alfa’s, whilst maintaining and even rather enhancing and accentuating further the organic Alfa styling DNA of the past. One only has to look at the formidable 21-inch alloy wheels, which evoke the “telephone dial”, a pure execution of the circular theme of the wheel itself. It was first seen in the 60’s and proudly carried by the Alfa 33 stradale. The wheel design has been further enhanced by special custom-made Pirelli’s…
The lateral profile of the car is reminiscent of the shapes of the Duetto and Disco Volante Spider, and the “Linea GT” profile of the Tonale is a modern day interpretation of the shapes seen on the GT Junior.
The “Trilobo” front end bears proudly the “Scudetto” grille, and the “3 + 3” headlights remember proudly the SZ and the Brera.
The cabin shapes have a distinct thoroughbred touch, and the materials are rich and inviting, with transparent panels in the centre console, and of course the DNA driving mode elector is a prominent element.
The Tonale is named after the Tonale mountain pass, which lies not far from the iconic Stelvio pass, and is equally breathtaking with eternal snow and water falls. Just come to admire it in Brussels…on the 9th of January. If you missed it, there is always a nice consolation for you: you can admire on the following days instead the new Giulia MY 2020…
Kia recently showed a stunning electric coupé with novel proportions. This Futuron made its public debut at the 2019 China International Import Expo (CIIE) in Shanghai. Its low-profile SUV coupe body makes a strong statement of intent for Kia’s future cars, which will be – as the manufacturer puts it – confident, sporty and modern, yet also elegant. At 4,850 mm in length, 1,550 mm tall and with a 3,000 mm-long wheelbase, it has an elevated ground clearance is matched with a low, lean body to create a dynamic, confident posture.
It is indeed a sports car… on an SUV platform. Clever.
Because this makes – like for instance in the Audi e-tron – room for the
batteries to be lodged beneath the cabin floor. The advantage is also that the elevated
stance of the car is therefore matched with a low center of gravity.
And that slightly more elevated stance is just what
you want in an urban car, even if it has the sleek shape of a coupé.

is powered by four powerful in-wheel electric motors. This e-AWD
system delivers as you can expect lively responses to driver inputs.
But the important hallmark here is its fluid, intriguing design. The front fender flows backwards from the front of the hood before plunging into the cabin itself, establishing a connection between the driving seat and the road ahead. The concept’s roof is a diamond-shaped panoramic glasshouse which sits atop the 360-degree core, in the best traditions of UFO and flying saucer design. It floods the cabin with natural light, and it also extends down the bonnet to give drivers an unparalleled view ahead. The glasshouse also incorporates a network of LiDAR (light detection and ranging) sensors capable of providing Level 4 autonomous driving features, enabling hands-off and eyes-off driving in most conditions.
Furthermore, the 360-degree theme is evident in the
lighting that illuminates a sharp character line encircling the Futuron’s body.
A new “tiger” face…
The newly-designed front of the car, like that of the
Imagine by Kia Concept first revealed earlier in 2019, expresses a new design interpretation for Kia’s future
With a wider ‘tiger face’ shape, the grille
incorporates the Futuron’s headlamps, an innovative ‘Star Cloud’ design which
gives the car a dazzling new night-time identity.
Flexible cabin space…
The layout of the electric powertrain and
incorporation of Level 4 autonomous
driving systems has enabled the creation of a spacious and flexible cabin
unlike any other vehicle on roads. The two
front seats are created out of flexible materials and can offer an upright
‘driving’ position, or a reclined ‘rest’ position, similar to the flexibility
afforded to first-class airline passengers. With the activation of the
Futuron’s autonomous driving features, the two front seats recline as the
steering wheel retracts. The ‘zero-gravity’ seating position this creates helps
to reduce fatigue on long journeys.
One of the most prominent features of the cabin is the
‘cockpit’ area surrounding the driver. The graphical user interface (GUI) of
the cockpit flows out of the driver-side door and wraps around the steering
wheel in a seamless arc. This merges the instrument cluster directly with the
audio-visual display at the center of the dashboard and is linked to the
display integrated within the surface of the steering wheel itself.
The GUI is operated by artificial intelligence
technologies, displaying useful information about the car various autonomous
driving, powertrain and navigation features, which creates a unique user
This is, according to Kia, what driving into the
(urban) future is all about. Just look at the photos here…
It had to happen. BMW cultivates pleasure of driving. And this also goes for their E-cars. Even more so, as they have excellent torque and therefore massive pulling power. And what’s more, you can use several motors at once.
So it was only a matter of time that a trial car with superpower is created. Here it is: BMW Group presented its “Power BEV” during its #NEXTGen event in Munich.
Just before we go further, just explain here a bit more on the #NEXTGen event: From 25 to 27 June 2019 the company invites selected international journalists, analysts and further stakeholders to “BMW Group #NEXTGen” at BMW Welt in Munich. With this event, The BMW Group chooses a new direction with regard to how it presents its future technologies, services and products.
But back to the car now. Indeed, BMW explores
with this “Versuchswagen” what is technically possible. A BMW 5 Series was
taken off the production line, and then fitted with three fifth-generation
electric drive units, resulting in a maximum system output in excess of …530
kW/720 hp. This transforms the 5-Series into a supercar: with this power, it accelerates
from 0 to 100 km/h in comfortably under three seconds.
But it is not only about straight line
performance, it is also about handling. A true BMW also puts a smile on the
driver’s face through corners, and so the engineers got to work on the chassis
Separately controlled motors provide unseen agility…
To this end, the chassis and powertrain engineers worked together particularly closely to maximise the car’s performance. Key to its dynamic superb qualities is that the two electric motors at the rear axle are controlled separately. This brings e-torque vectoring into play, which enables maximum drive power to be translated into forward propulsion even in extremely dynamic driving manoeuvres.
The result is more effective and precise control
than with a limited slip differential, because actively targeted inputs are
possible in any driving situation. By contrast, a limited slip differential
always reacts to a difference in rotation speed between the driven wheels, and therefore
is slower to react.
As said, the drive system comprises three
fifth-generation drive units, each of which brings together an electric motor
and the associated power electronics and power take-off within a single
housing. One is mounted at the front axle and two (a double drive unit) at the
rear axle. Another notable aspect of this generation alongside its eye-catching
power is that it is entirely free of rare earths. An electric motor of this
type will make its series production debut in the BMW iX3. The iX3 will only
have one motor, though, rather than three.
A series production car forms the basis…
As said, a current BMW 5 Series production
model serves as the donor car for the Power BEV. Integrating a drive system of
this type into a production car represents a serious technical undertaking, but
it has been achieved here with absolutely no restriction in passenger
compartment space. This makes it far easier to assess this drive concept
It has also allowed the engineers to look
even more effectively into the possibilities opened up by two separately
controllable electric motors at the rear axle with e-torque vectoring.
And that means, in future series-production
vehicle projects, that the right technology can be selected for the model at
hand. Customers will therefore be provided with the most appropriate technology
for their choice of vehicle concept. Wow! Needless to say, we are now looking
to the E-future with a very broad smile! Driving pleasure will be certainly
part of it!
