Jeep has given the SRT treatment to its flagship Grand Cherokee and the result is the creation of the firm’s fastest and most potent production model ever. How does a 0 to 60 mph (96 km/h) acceleration of 4.8 seconds or a quarter mile time in the mid-13 second range sound? This is what the Grand Cherokee SRT8 is capable of, and the reason for these figures lies under the SUV's bonnet.
The Chrysler Group’s Street and Racing Technology division (SRT for short) equipped the performance SUV with an all-new 6.4-liter HEMI V8 engine that delivers 465 horsepower and 465 lb-ft (630 Nm) of torque.
Compared to the outgoing model powered by the 6.1-liter HEMI V8 unit, the new Grand Cherokee SRT8 has an extra 45HP and 45 lb-ft (61 Nm) of torque. About 90 percent of peak torque is available between 2,800 and 6,000 rpm. The Grand Cherokee SRT8 can do 0-100-0 mph in the mid-16 second range and has a top speed of 155 mph (250 km/h).
