Jeep Grand Cherokee Trackhawk 2018 UK review
Meanwhile, Jeep has timed this car (and it has an onboard launch control acceleration timing app that allows you to verify this for yourself) doing 11.5sec standing quarter miles – which is pretty much Porsche 911 Turbo or Nissan GT-R pace. And if the mere idea of such a thing seems more than a bit absurd? Just wait until we get on to the reality.
The Trackhawk’s V8 is the kind of engine that clunks roughly into drive and then doesn’t so much creep as heave its way forward at idle. Thank heaven there’s a warning light to tell you if you’ve left the foot-operated parking brake on, because it might take an awfully long time to notice otherwise.
Despite having a widely leather-bound cabin and a good amount of onboard infotainment tech available, the Trackhawk isn’t a very convincing luxury SUV. Jeep’s interior fittings aren’t very rich or substantial and its infotainment set-up doesn’t exactly flatter a £90,000 luxury car. In fact, a direct comparison between this driving environment and the one in the Audi SQ7 or Porsche Cayenne Turbo wouldn’t be too flattering on the Jeep any which way you looked at it.
Theres also little you could call refined about this car’s driving experience - not that you’d change much about that. The Trackhawk bristles with the vociferous energy of that megastar engine at all times. It rumbles and woofles away on a trailing throttle, only to go through layers of sonic transformation as you probe into the accelerator travel.
The distant whine of that supercharger gets gently faded up as you tip into the pedal, getting louder through the middle of the range, only for more crackling combustion noise to come fighting back as you begin to feel the carpet under the edges of your shoe. Few modern performance engines are as characterful, as exciting or as wonderfully, rabidly genuine to listen to. And I’m not sure if any provides a more incongruous or improper-feeling turn of speed, which builds to a deliciously dramatic and noisy crescendo at high revs like the perfect antidote to the modern sledgehammer turbo V8.
The Grand Cherokees chassis works well enough as a delivery mechanism for the charms of that engine up to a point, although it’s hardly what the engine deserves. Some seriously uncompromising suspension spring rates attempt to cover for the absence of many of the technologies that help the Jeep’s rivals to apparently defy physics and handle so well, such as active anti-roll bars, proper torque vectoring and four-wheel steering. And so the Trackhawk’s low-speed ride is fidgety and brusque, and higher-speed composure is less than assured at times. The suspension has adaptive dampers, but the Jeep still lacks the breadth of range that might otherwise allow you to relax at the wheel and cover big miles at a fast, effortless stride.
Lateral body control and handling balance are both good, though, and there’s certainly enough togetherness and composure about the rest of the Trackhawk’s dynamic picture that you can thoroughly enjoy a brisk strop down a fairly smooth road. Vertical composure over tougher roads is less good, and the car’s stability thereon isnt helped by steering that’s overly light in most of its driving modes and could better communicate front tyre load, but neither problem is too objectionable or persistently bothersome.
If you’re the sort of person who thinks that if you’re going to offend your neighbours and risk your social standing with a fast SUV, you might as well do it properly, get yourself a Helljeep. That’ll do it.
Moreover, if you’ve owned and loved proper American muscle cars but your life has developed beyond their typical range of usability, the Grand Cherokee Trackhawk might even deserve to be the only car in your thinking. It is, for its many and obvious flaws and failings, a superbly singular thing.
From a simple bang-for-buck perspective, is there another way to buy 700bhp straight out of the showroom for £90,000 at the moment? Not that I know of. Is there a more straightforward, direct, unpretentious and genial car than this among a fairly disagreeable bunch of modern super-SUVs? If so, I’m not sure I’ve driven it.
The only serious word of warning we would give to prospective customers concerns tyres. We tested an Italian-spec, left-hand-drive car on Pirelli P-Zero tyres, which, oddly, won’t be available in the UK; here, the Trackhawk will come on all-season rubber as standard. Shall we pause and think about that for a second? 700bhp, 2429kg and super sports car pace, all on squirming treadblocks. Gulp.
I wonder if ‘one-season’ might be a better description for those tyres, given the torrid time a Trackhawk might give ‘em. I also worry about what they might do to a handling compromise that doesn’t have abundant lateral grip or stability at the best of times.
All of that stuff’s just a hunch, of course. Maybe the Pirelli Scorpion Verdes are entirely up to the challenge. But if it were my car, I’d put a set of proper performance ‘summer’ tyres in the corner of the garage to be fitted sometime in late April 2019. And then I’d be delighted just to worship at the altar of this car’s V8 as regularly and as zealously as I could get away with.
