The Jeep Grand Cherokee SRT isn’t Subtle or quiet, but IT’S Certainly entertaining. noel ebdon Tries out america’s performance SUV
years, the US automotive approach to performance models has been to simply ramp up the power, and then some. Everything else was pretty much ignored. Now, it’s more about a combination of factors. The CCS are still there, but now the rest of the package is moving up to match what’s under the hood.
Lurking under that bonnet is a potent 6.4-litre V8 with Fuel Saver Technology that delivers 475 bhp and 470 lb ft of torque. Performance includes acceleration from 0-100 km/h in 4.8 seconds, 0-161-0 km/h in 16.3 seconds, a quarter mile in the mid-13 second range, and a top speed of 257 km/h.
Stopping from those speeds requires some big brakes, and the huge, standard SRT Brembo brakes can be upgraded further with a high-performance brake pack- age that features two-piece aluminum and high-performance rotors in the front and the rear. But to be fair, the standard items are 100-per cent up to the job.
The brakes are helped by the fact that the SRT’S weight has also been reduced, by using a number of aluminium suspension components.
The V8 is mated to a slick, eight-speed automatic transmission, which Jeep has engineered to optimise shift quality and shift points for fuel economy, performance and drivability.
According to the press blurb, “the intelligent software takes into account variables, including engine torque gradients, kick-down events, longitudinal and lateral acceleration, grade changes, friction detection and downshift detection to determine the appropriate shift map.” Basically, it
