Audi SQ7 TDI packs 48V electric compressor, 664 lb-ft

Take a look at the new Audi SQ7 TDI. It's the first time Audi has done an S performance version of its flagship sport-ute, and packs under the hood a 4.0-liter V8 turbo diesel engine mated to an eight-speed automatic and all-wheel drive. It produces a potent 435 horsepower, and an absolutely bonkers 664 pound-feet of torque. The Audi SQ7 TDI produces a massive 664 lb-ft of torque. Impressive as it is, though, that doesn't even tell the full story. That's enough to make us forget it wasn't there in Geneva. It's also more torque than just about anything the Volkswagen Group makes – short of the Bentley Mulsanne Speed and the new Bugatti Chiron. Not even the Lamborghini Aventador SV or Bentley Continental GT Speed can touch that torque figure. Nor can competition like the Porsche Cayenne S Diesel (with its 385 hp and 627 lb-ft) or the BMW X5 M50d (381 hp and 546 lb-ft). It may not surpass the old twelve-cylinder Q7 6.0 TDI (with its 493 hp and 738 lb-ft), but still trounces the VW Touareg V10 TDI (309 hp and 553 lb-ft) – which was strong enough to tow a jet airplane, while the new SQ7 is fast enough to out-drag one (as you can see from the video below). Impressive as it is, though, that headline-grabbing torque figure doesn't tell the full story. To get there, Audi employed two conventional, sequential turbochargers and a third compressor that – in an industry first that's been a long time coming – is powered electrically. The engineers in Ingolstadt installed a beefier 48-volt electric subsystem to power the electric compressor (among other systems) and its latest valvetrain tech for the first time in a diesel. The result, Audi says, is a lack of any perceptible turbo lag – and a 0-62 time quoted at 4.8 seconds, en route to the typical electronically limited top speed of 155 miles per hour. As if that weren't enough, Audi also equipped the SQ7 TDI with an optional suspension package that coordinates the activities of three systems. There's a differential, a four-wheel steering system, and a clever electromechanical roll stabilization system that employs an electric motor (made possible once again by that 48-volt system) and a three-stage planetary gearbox to keep it all level and improve ride quality over rough surfaces. The sum total is an impressive technological tour de force on Audi's part, but one that we may just have to admire from afar.

Which would you rather have, Audi's RS5 or Mercedes' C63 AMG 507?

If you're in the market for a German sports coupe with a naturally aspirated V8, run, don't walk, to your nearest dealer because they are going to be gone very soon. European fuel economy and emissions rules have conspired to force automakers into seeking forced-induction mills. Motor Trend personality Jonny Lieberman is hosting the retirement party in the latest Head 2 Head video, where he takes on the 2014 Audi RS5 and 2014 Mercedes-Benz C63 AMG Edition 507 to decide which is the ultimate Teutonic V8.
To make the decision harder, Lieberman challenges the duo on the first soaking wet roads that Southern California has seen in ages. It forces the coupes to confront some of the actual weather that the rest of the country encounters regularly and serves to even the playing field somewhat between the charismatic rear-drive Mercedes-Benz and the all-wheel drive Audi.
It really is the end of an era for these coupes. The next Audi RS4 is rumored to switch to a twin-turbo V6, and while Mercedes won't officially admit it, the next C-Class AMG will likely switch to a 4.0-liter twin-turbo V8. And we already know the next BMW M3/M4 will rely on a 425-horsepower, 3.0-liter inline-six. Let's enjoy these eight-cylinder German giants while we can, and scroll down to watch the video.
