Audi SQ7 TDI (2016) review
► Go-faster version of Audi’s giant SUV
► Seven seats, 429bhp and 4.9sec to 62mph
► ‘Borderline madness but hilariously endearing’
Audi has a new performance SUV called the SQ7. It’s the second Q-series model to receive an S designation, and shoots instantly to the top of the Q7 range. And instant is a pretty good word for this ridiculous machine, for the SQ7 is also the first production vehicle to ever feature an electrically powered compressor, or EPC, which is designed to speed up the response from its 4.0-litre twin turbo V8 diesel engine. Because, obviously, 4.0-litre twin-turbo V8 diesels need all the help they can get with that sort of thing.
Have you ever wanted to be the bane of hot hatch drivers’ lives? Or perhaps you once were a hot hatch aficionado, forced to give up your life of tyre-squealing fun in the face of domestic demands and corporate image projection? Well, in the way that we once used to describe really good hot hatches as being faster cross-country than a supercar, the 429bhp Audi SQ7 is an SUV that’s quite possibly faster cross-country than a really good hot hatch – and we don’t mean because its off-road capability allows it take a more direct route…
Could you, possibly, be over-egging this pudding, pudding?
At first encounter, you might think so. The electric compressor exists to fill in any holes in the response time of the V8’s two conventional turbos off idle, which are already plumbed in sequentially but still rely on exhaust gases to build boost; the EPC simply pulls power from the SQ7’s new 48-volt electrical system whenever it needs to spin up, meaning it hits 70,000rpm in about a quarter of a second, sending a short pulse of motivation into the intake to help get the party started.
However, if you’re expecting this to feel like a shot of nitrous every time you put your foot down, you’ll be disappointed. This is still a 2.3-tonne vehicle and initially the sheer mass of the thing conspires to disguise just how fleet of foot it really is. But then you start to notice how rapidly other cars get smaller in the mirrors, and shortly after that you begin to process what’s happening with the chassis.
What is happening with the chassis?
The same 48-volt system that allows the electric compressor to function is also juicy enough to run an electro-mechanical active anti-roll system – basically the same as that fitted to the Bentley Bentayga (which shares the Q7’s platform). This comes as an optional extra on the SQ7 as part of a driving dynamics package that also includes a torque-vectoring sport differential at the rear and four-wheel steering. In combination, these have a tendency to make Einstein look like he was off his head.
Dial up the Dynamic driving mode, which also firms up the standard variable dampers and air suspension, and although the active anti-roll doesn’t neutralise cornering lean altogether it does allow you to carry far more speed through a sequence of bends than anything of this size and stature should really make possible. A slight lateral pogoing motion tells you when you’re approaching the limit, though the sport diff and the four-wheel steering help keep the front end so nimble and pointy you still carry on taking greater and greater liberties.
Eventually you find yourself at the bottom of a mountain road with the (also optional) carbon ceramic brakes on fire and your perspective on performance motoring irrevocably warped, wondering exactly what just happened.
But seriously, what is the point of this monster?
We suspect this is one of those ‘because they can’ kind of deals. Only a sadist really needs a seven-seater SUV that can out-sprint all but the three most potent hot hatches currently on sale before attempting to out-corner them. The visual makeover is likely to be as endearing to other motorists as Jeremy Clarkson at a Greenpeace convention, the interior is finished to a high standard but totally devoid of charisma, and despite the 70 grand price tag you still need to spend more to make it really behave like an animal.
Still, it makes a great V8 noise, which becomes more or less subtle depending on driving mode, and the Comfort settings cope tolerably well with the optional 22-inch alloys should you really feel the need to look totally obnoxious. And honestly, these are so sexy we just might – though UK buyers are probably better off sticking to the standard 20-inch wheels.
Verdict
A colleague described this car as physically impressive but difficult to love. We’re not so sure – there’s just something so hilariously endearing in the way this massive bus can charge along a twisty bit of road that it might just ignite the spark of permanent passion. Perhaps not least because in spite of all its toys, this is still borderline madness and requires a fair degree of input from the driver to manage and maintain. We cannot wait to see whatPorsche does with this platform when it launches the next generation Cayenne…
