2021 Jeep Grand Cherokee Trackhawk Performance

如果你有兴趣在一辆SUV悍妇摩托r, you're likely obsessed with straight-line performance. The Trackhawk excels in this department, offering an unbeatable 707 hp and 645 lb-ft of torque. Although other 6.2-liter supercharged HEMI Hellcat-powered products like the Dodge Challenger SRT Hellcat Redeye send their power to the rear wheels, this is a Jeep. Thus, power is split between both axles with an eight-speed automatic transmission helping distribute power to the 4WD system. Besides the Jeep badge, 4WD just makes sense, as drifting a rear-wheel-drive SUV with this much power is probably not the greatest idea. Sending power to all four wheels also reaps benefits in the 0-60 mph sprint, which is achieved in just 3.5 seconds. Keep going and the quarter-mile can be achieved in as little as 11.6 seconds. Top speed is impressive too, with the limit arriving at 180 mph. However, while the Trackhawk is certainly more capable than the regular Grand Cherokee in the corners, it can't hold a candle to the likes of the X5 M and Cayenne Turbo, SUVs that do a great job of acting like proper sports cars. Nevertheless, the Trackhawk can be pretty versatile, offering a towing capacity of up to 7,200 lbs.

The Grand Cherokee Trackhawk is a standalone model at the top of its range and comes in only one configuration. This means you get a 6.2-liter HEMI engine with a 2.4-liter belt-driven supercharger from IHI. Combined, they generate a total of 707 horsepower and 645 lb-ft of torque, although as the Challenger range has proven, much more power is potentially possible. Could a Redeye version come someday? Maybe, but for now, this thing has more than enough oomph to scare your kids on the way to school. It can potter along nicely too, but as you'd expect of something with this much power, acceleration in any situation is absolutely effortless. Assisting with this consistently brutal yet manageable output is an eight-speed TorqueFlite automatic transmission that allows for manual shifting with the aid of steering-mounted paddles. Left to its own devices, it will shift smoothly and quickly, but it's just as impressive when you take manual control too. Responses are instantaneous, ensuring that the time to get from one gear to the next is so short that you don't have time to think about how sick you feel from the insane g-forces.

As you can imagine from something with a supercharger that draws 80 hp to run, gas mileage is not the Trackhawk's strong suit by any stretch of the imagination. The latest official EPA ratings indicate that the Jeep Grand Cherokee Trackhawk SUV will achieve 11/17/13 mpg on the city/highway/combined cycles. To be fair, the BMW X5 M isn't all that much better, achieving 13/18/15 mpg on the same cycles. However, the Bimmer has a smaller tank compared to the Jeep and will thus offer similar range. The Trackhawk's 24.6-gallon tank should return around 320 miles of range with mixed driving if the EPA figures are to be believed, but the reality will be considerably worse, especially if you find a whining supercharger and a roaring V8 as addictive as we do.
