For their 2015 model range, US car specialists GeigerCars.de have boosted the cache of the Jeep Grand Cherokee with performance modifications that make it the chief of all Grand Cherokees.

The 6.4-liter HEMI V8 engine with Geiger supercharger upgrade now makes significantly more power than the already potent standard version. Installed in-house by GeigerCars.de, the 2.9-liter supercharger, comes with an intercooler and internal engine modifications including uprated pistons. With the new ECU with its altered fuel and ignition software wired in, output rises to a major league supercar level of 718 hp, with 776 Nm of torque. The larger oil cooler option costs 1,430 euros. Against the stopwatch, the new numbers are quite spectacular. The SRT suffix in the standard cars name stands for ‘Street and Racing Technology’ a label that is even more appropriate now as the supercharged GeigerCars.de version blasts to 100km/h in just 3.9 seconds, and on to 295 km/h. This is a sensational performance for an SUV that will seriously upset supercar drivers. To ensure that this newfound performance can be safely transmitted to the tarmac, GeigerCars.de also offer performance suspension modifications with sport springs (1,250 euros) that drop the ride height, and uprated anti-roll bars (650 euros) to further reduce body roll in fast cornering. 2015 GeigerCars Jeep Grand Cherokee Rear Angle Further gains in grip as well as looks come from the wheel/tyre upgrade package consisting of 10.0x22-inch alloy wheels shod with 305/35R22 rubber for 5,490 euros.
