One of the absolute highlights of two days of Jeep driving amidst the beautiful scenery of the Italian Lago di Garda was a stint behind the wheel of the Grand Cherokee Trackhawk and the SRT. The Jeep® Grand Cherokee is the flagship of the Jeep brand and the most awarded SUV ever, and this gem of a car created the premium SUV category 27 years ago and with more than 6.4 million units sold since its introduction. More about this Jeep Grand Cherokee in its “normal” version(s) later, we focus here on the stunning Trackhawk and SRT versions.
Indeed, it had to happen, and the whole car world was actually expecting this: the more than 700 HP V8 of the Dodge Hellcat, the “muscle car” par excellence, was to be dropped in the engine bay of the Jeep Grand Cherokee. It all happened last year, and now we had the chance to drive it: the supercharged 6.2-litre HEMI® V-8 engine, delivering 710 hp at 6000 rpm, mated to an 8 speed automatic transmission. High-strength, forged-alloy pistons, powder-forged connecting rods and sodium-cooled exhaust valves all add to the power of the Supercharged 6.2L V8 engine. Do not expect a hissing monster though.
The massive V8 burbles smoothly through slow urban traffic through the villages around the Lago di Garda, and progress is silky smooth. Until you floor the throttle. Supercar acceleration is the instant answer, and the engine growls away. 0 to 100 km/h is reached in some 3,7 seconds, the top speed is 289 km/h, if you only dare.
Of course, good traction is provided for with all this power. A “Quadra-Trac” active on-demand four-wheel-drive system, which also includes a rear Electronic Limited Slip Differential (ELSD) and a single-speed active transfer case is at your disposal.
Not yet an expert in unleashing all this power and putting it “just right” on the tarmac? Good to know that there is a “Launch Control” on SRT® and Trackhawk® , which optimizes track performance by coordinating the engine, transmission, driveline and suspension for a textbook launch and consistent straight-line acceleration.
The traction management system has been specifically retuned for the Trackhawk and SRT versions as “Selec-Track.” It features five vehicle setting – Auto, Sport, Track, Snow and Tow – to allow the driver to achieve the best driving experience on any surface.
The suspension is of course well tuned to this extra power, as well as brakes, and the Grand Cherokee remains eminently drivable.
Don’t forget there is also the Bilstein® Adaptive Suspension system, which can adjust the dampers for sport or track performance if desired, while the rear Electronic Limited Slip Differential features a four-point axle mounting to better distribute the massive power to the wheels.
For the heavier terrain work, the Quadra-Lift air suspension system allows you to change the ride height of the Grand Cherokee up to a maximum ground clearance of 28 cm.
We were deeply impressed by its handling and ride when driven with more abandon, and how perfectly balanced the whole car was. The unique driving experience is further enhanced by excellent seats and instrumentation, with not only a beautiful central rev counter, but also a special “Performance Page” on the central touch screen, where you can see anything as time of your acceleration, G-Force, all engine data like oil temperature, etc.
We enjoyed also having a stint at the wheel of the more suave SRT. Not that on the urban scenic roads around the Lago, you could test fully the difference in performance compared to the Trackhawk. Under the hood of the SRT version growls the 6417 cc V8 Hemi, good for 344 kW or 468 HP @6250 rpm. The same 8 speed auto transmission as in the Trackhawk knows this engine also needs to be revved to reach all out performance, as maximum torque of 624 Nm is reached at 4100 rpm. Of course, also here the Launch Control and the choice between five dynamic Drive Modes with the Selec-Track® System, as described above.
We enjoyed the same beautiful well balanced handling, indeed an SUV which also truly stands out if you expect that extra performance. Using launch control, it will still be able to catapult you from 0 to 100 km/h in 4,9 seconds.
We let you enjoy the photos here, and we dream along with you about this unforgettable experience… and there is more Jeep news to come with driving impressions of the full range!
