The most powerful SUV is believed to be the new Jeep Grand Cherokee Trackhawk which will be launched in 2018. This is the third Fiat Chrysler car to feature an unhinged V-8, having a quiet engine. The Trackhawk has all-wheel drive alleviating the tire-spinning proclivities of the engine. The new Jeep Grand Cherokee Trackhawk has more traction compared to a Hellcat model.
Engineers name the new Jeep Grand Cherokee to be one of the most powerful SUVs
Its engine weight 259 pounds, adding over the heavy Grand Cherokee SRT of 475-hp. However, developers argue that this car can reach 60 mph in only 3.5 seconds. A Jeep is expected to reach 116 mph in 11.6 seconds, but Trackhawk is bound to defy all previous beliefs, flying with 180 mph and no electric controller. To make the car quickly move out depends on the feature which controls launching called Torque Reserve.
This helps the supercharged bypass valve to remain open for a while some particular cylinders are fuelled to limit torque before the release of the brake. The Dodge Challenger RT Demon shares the same feature. They both have an A/C evaporator used to cool the intake charge. Otherwise, the supercharged Hemi V-8 engines of 6.2 liters is left alone, down to its forged pistons, its blower pushing with 11.6 psi and sodium-filled exhaust valves.
It has a lot of competitors and it shares many features with cars like Dodge Challenger RT Demon
Peak torque is reduced through exhaust routing issues, by a five lb-ft to 645. Jeep decided to strengthen the eight-speed automatic transmission, outfitting it with sprockets and forged chain, but also with a wider chain for the transfer case, adjusting the rear distinction between it and the Hellcat. In the normal process, the front-to-rear torque split of the transfer case of 40/60 appears to be the same with the one in the Grand Cherokee SRT.
This car can work in tow mode. Car owners may use it to carry up to 7200 pounds, being equal to another Hellcat-powered creation. Based on the information provided by the Mopar performance catalog, the supercharger and the V-8 engine of the Hellcat together weigh eight hundred pounds. This is heavier that the Grand Cherokee SRT’s Hemi engine of 6.4 liters.
To make up for the additional mass of the Trackhawk, engineers altered the front springs, diminishing them by 9 % and the rears were stiffed by 15%. All in all, this car is listed as the most powerful SUV, among Porsche Cayenne, Bentley Bentayga, and Mercedes-Benz’s G-class.
