Audi SQ7: UK Review

Diesel is dead, long live the (mega) diesel!



The Audi SQ7 is a very interesting car. From its 435hp twin-turbo 4.0-litre V8 diesel and 48V-driven 'Electrically Powered Compressor' combination to the 4.9-second 0-62mph time there's plenty to arouse PH interest. Even it is, ultimately, just a very fast diesel Q7.

Let's deal with that elephantine aspect first. I've always considered the Q7 the very embodiment of the brand's less favourable qualities. Owners, feel free to join the comments thread and tell me I'm full of it. But it's always struck me the key motivation for buying a Q7 is arriving in an Audi showroom and saying "I just want the biggest one". In the case of the SQ7 you can now extend that to "the biggest AND fastest one", like that makes it any more palatable.

Let's face it, you'll not be buying it on looks. Much as I didn't like what the original Q7 represented I could at least accept its successful upscaling of Audi design and values. This new one though? The grille looks disproportionately large, the overhangs ungainly and the previously clean shape seems to have gained all sorts of unwelcome surface 'detailing' and heavy handed sculpting. But it presumably fits the bill for those who just want as much Audi as they can get. Unless interior space is a priority; for all its ginormous external proportions there's not quite as much room inside the cabin or boot as you might expect.

Not going to miss it...

Stay on target
Anyway. Off the anti-Q7 soapbox. What about that fascinating engine? It is genuinely amazing, however the shifting favour against diesel manifests itself in coming years. I'll work on the basis you're probably not tickled by the idea of an eff-off V8-powered SUV if tree-hugging features highly on your list of favoured recreational pursuits though. Because if you want a large, family friendly SUV with an Audi badge on the nose and more than adequate power, then the regular 3.0 TDI is up to the job.

No, if you're looking at the SQ7 it's for reasons more than just fuel economy and range. This is a properly rapid car. Not 'rapid for a diesel' or 'rapid for an SUV', just rapid full stop. Whatever it looks like and whichever pump it fuels from that's got PH merit.

Like the previous V12 TDI Q7 this is one of those 'all about the engine' cars that geeks like us can appreciate too. The cylinder count and configuration are a sound start but the addition of the Electrically Powered Compressor to the two exhaust-driven turbos gives it astounding punch. The EPC's job is to prime the induction charge before the turbos have spooled up, the way the boost gauge shoots up before you even deploy the throttle offering the first sense of what it's up to. Suitably awoken throttle response is razor-sharp, the V8's 664lb ft from barely more than tickover making a mockery of the SQ7's bulk. Acceleration is angry, quite frankly, and that sub-five 0-62 time feels a conservative estimate. Nor does that rate of progress abate either.

It's a fantastic engine, no doubt about that

Smarty pants
There's some really clever stuff going on here too. This is the first time Audi Valvelift System has been used on a TDI engine and it uses variable opening of the exhaust valves to control the sequential turbos. At low revs one exhaust valve remains closed, gases directed to the 'active' turbo as Audi has it. Above 2,000rpm and when the loads dictate the second valve opens to wake up the second turbo. Before any of this has happened, of course, the EPC has already been on the case.

And it sounds great too. There is a 'sound actuator' in the exhaust system but from the outside there's enough V8ness to suggest fakery plays only a supporting role. Suffice it to say even the tickover rumble inescapably signifies the SQ7's intent. Given it costs nearly £20K more than an S Line 3.0 TDI you'd rather want that though.

Making sense of all this performance is a chassis fully stocked with all the latest gizmos, on the assumption that you're willing to pay the additional £5,700 for the Driving Dynamics Sport Pack. Box ticked, that 48V network operates the active anti-roll system (given it utilises up to 885lb ft of torque you can appreciate why it needs the electrical grunt) and there's also four-wheel steering, all of this and more adjustable via the modes in the Audi Drive Select. Also included is Audi's trick torque vectoring Sport Differential for the rear axle, experience from our S4 Avant long-termer suggesting this can have a transformative effect on the way fast Audis go round corners. This lot on top of the standard air suspension, multi-mode dampers and all the rest. Yes, an awful lot of tech for a family-friendly SUV.

Tech does an admirable job against the weight

No need to apologise
And means you can drive it in a suitably unapologetic manner, should the mood take you. While it hardly shrinks around you the combination of four-wheel steering helping you on turn-in and the Sport Differential deploying that incredible power and torque on corner exit you've got a machine that can get around corners way more quickly and dynamically than you'd credit. Nobody will love you if you drive it thus - not your passengers and certainly not your fellow road users. But it's undeniably impressive. And the deployment of that incredible urge is never less than shocking.

As a package it's a typically polished affair too, Audi's mastery of tech and the presentation thereof all top notch. Well, mainly. Does anyone actually use touchpads on the move? I can barely use them when stationary but the MMI interface is awkward to use unless you play by the rules. And the semi-autonomous driver aids are about as 'smart' as the motorways they're intended to conquer. Put it this way, having the cruise control try and accelerate you back to 70mph when you set it at 55mph for a temporary restriction is scary. When it then clocks the signs and brings you back to an obedient 50 you then get trucks on your back bumper flashing their lights in your mirror in a most un-Audi like role reversal. Who'll be brave enough to contest a fine on the basis that their car's cruise control overrode their input and automatically increased the speed to beyond the posted limit? Good luck with that one but it'd be a fascinating case study to follow.

You'll have got the gist now by sure. This is a big, fast Audi. An interesting one, if not necessarily a commendable one. And possibly spectacularly mistimed if the tide really is turning against diesel. For those with an eye for technical intrigue though a car with plenty to occupy your curiosity. And I mentioned it was fast, right?

The problem with this car is it's engine !! - who in their right mind is going to be willing to keep this thing on the road when it is ~10 years old. 2 turbo's, electric compressor, 2 EGR systems, Ad-blue injection, 2 DPF's and 8 common rail injectors plus their pump. There is about £10 to£20k of kit on this engine to deliver the performance and let it be legal. If you compare this with the kit on a petrol engine delivering similar performance (either V12 or V8 twin turbo) there are so just many huge bills that are going to arrive to keep it on the road that everything like this is going to end up as scrap

Technical master piece - yes. Sensible - not in any way, shape or form

Of course all of this is a combination of CO2 legislation and "my willy is bigger than yours" between the german engineers at BMW, Audi and Merc. If you want a fast car, stick to petrol and with turbo's if you have to

Rant over!

These things are just wrong in the "big picture"
(forget whether people like SUV's - if they want to travel high up and feel secure with 4WD and they can afford it then that's their business)
What's wrong (as I said before) is the "mega power diesel"

Not only is it wrong from a sustainability point of view (destined from an early death due to complexity) but even the CO2 arguement is highly likely a load of h***e s***t as well

The energy consumed in developing and then manufacturing these technical white elephants is enormous and then the sales are tiny
Whilst from an engineering point of view managing to get ~40 mpg from a Q7 on the NEDC test is a piece of genius

a) In the real world they will be down in the low 30's or high 20's
b) Vast amounts of CO2 will have been generated creating them
c) Their NOx emissions will be horrendus (or it's drink Adblue like a fish which needs CO2 to make adblue in the first place)

Honestly, for this type of "flagship" model, a good old fashioned 6 or 7 litre V12 makes so much more sense at just about every level (including whole life CO2 (or energy) consumption)
It's just a stupidity of marketing and it's probably one of the last of it's breed thank goodness

The marketing thinking will have been "people like buying 2.0l TDi's because of low cost of ownership like SUV's and they , how do we make TDI & SUV look "sexy", I know, let's win Le Mans with a TDI and then put really powerful TDI in our biggest and most expensive SUV. No one with any sense will buy one but it doesn't matter because we'll hardly sell any and we'll make it so expensive that even with a small number of stupid people we won't loose too much money overall and it'll be cost effective marketing"

Yes, it really is that cynical

Well times up !! Le Man is cancelled and the powertrain du jour is petrol/hybrid (slightly more rational if you care about whole life CO2) and we won't see many more of these "choclate tea pot" mega-diesels because the americans (and more importantly) the chinese rightly won't have them due to emissions

Sorry, lied before when I said "rant over" - needed to have a 2nd go !!
