The aftermarket specialists from GeigerCars have released an upgrade kit tailored to the Jeep Grand Cherokee SRT. Most of the work was done underneath that muscular hood where resides a large HEMI V8 6.4-liter engine that now comes with a 2.9-liter supercharger, a remapped ECU and beefier pistons. These changes have boosted output of the engine to a total of 718 PS (528 kW) and a maximum torque of 776 Nm (572 lb-ft). After the power bump is implemented, the high-performance SUV will run the 0-62 mph (0-100 km/h) sprint in 3.9 seconds and top out at 183 mph (295 km/h).
Aside from getting a stronger engine, the Jeep Grand Cherokee SRT also has custom 22-inch alloy wheels, a body wrap, stronger anti-roll bars and sport springs. All these modifications will set you back a rather hefty €23,900 on top of the car’s €66,900 price tag.
