Hennessey Performance presented some years ago a tuning package for the Jeep Grand Cherokee SRT8, that made the 6.4 liter HEMI engine of the car, produce, 816 hp and 1115 Nm of torque, enabling it to do the 0-60 mph in 3.1 seconds.
The car was also equipped with a modified gearbox to withstand the extra power, while it had new lightweight wheels and a carbon front splitter. Only 24 cars were produced and they were all sold for close to $250 thousand.
