But which one should you buy? They both deliver 475 horsepower and 470 pound-feet of torque to all four wheels through an eight-speed automatic transmission. They both do 0-60 in around 4.4 seconds, and both boast top speed numbers that will handily land you in jail if written on a speeding ticket. Choosing between the two, then, is a bit more nuanced than which is faster.
That said, the Jeep is probably a bit quicker at the track than the Dodge. We'd wager than the Grand Cherokee SRT's 5,104-pound curb weight (versus 5,510 for the Durango SRT) and 114.8-inch wheelbase (versus 119.8) will pay small dividends in acceleration, cornering, and braking performance. So, if that's the only category by which you believe these SRT-fettled SUVs should be judged, choose the Jeep.
But let's get real here for a moment. As much fun as it is to wrangle a brutish ute 'round a racetrack – and trust us when we tell you it's a blast – the number of hi-po SUV owners who will ever show up at Bondurant in an SRT-badged 4x4 is probably in the single digits. So, when evaluating which of the two Hemi-powered vehicles is right for you, ultimate lap times are probably of little concern.
If you're choosing between these two overpowered players, practicality is probably just as important as performance. And in that category, the Durango SRT comes out on top. For starters, the Dodge is a three-row SUV with six seats, whereas the Jeep is a two-row, five-passenger platform. Fold down the rear bench and there's 84.5 cubic feet of cargo area in the Durango, versus 68.7 in the Grand Cherokee. And if you tow, the Durango SRT's 8,600-pound max rating handily bests that of the Grand Cherokee SRT's 7,200-pound capacity.
Ask yourself what's most important: performance or practicality. And then consider the price. The Dodge is nearly $4,000 less expensive than the Jeep. In this contest, where we're basically picking nits, we'll give the win to the Durango SRT for winning two out of three categories. But we reserve the right to rethink our arguments entirely just as soon as the even-more-bonkers 707-horsepower Jeep Grand Cherokee Trackhawk joins the fray.
