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.

Audi to abandon CVTs?

The continuously variable transmission is one of those technologies that seems to make a lot of sense on paper, but in reality, almost always numbs the driving experience. That's one reason why Audi, according to reports, is planning to phase them out.
One of the first automakers to implement use of the CVT, Audi mates CVTs to larger engines than many other manufacturers, which typically install them on scooters, hybrids and small-displacement hatchbacks. But the time of the Audi CVT (which it calls Multimatic) may be near its end as a report from Australia indicates that Ingolstadt is moving toward a two-gearbox lineup that does not include the rubber-band transmission.
Instead, Audi is said to be focusing its attention on the S-tronic dual-clutch transmission and on conventional torque-converter automatics - although the development of beefier DCTs could spell the end of the Audi slushbox, as well. We've reached out to Audi for comment, so watch this space for confirmation.

Audi TT Sportback Concept rounds out an icon

That German automakers seem singularly fixated on filling any white space between their models isn't new - the last decade-plus has seen their showrooms overflowing with niche models, some of which seemingly occupy sub-genres of sub-genres. To our eyes, there's often diminishing aesthetic and utilitarian returns to go along with the heightened price tags that accompany these models, but we're beginning to think Audi is tackling its personal diversity initiative best. Unlike the often heavy-handed designs from rivals (we're looking at you, BMW), Ingolstadt seems to be doing doing a more graceful job of carving out models between models. The latest proof of this is the TT Sportback Concept, just unveiled here at the Paris Motor Show.
After showing off its Allroad Shooting Brake Concept in Detroit and, more recently, in the Offroad Concept in Beijing amidst rumors of the TT sports car platform expanding into an entire family, we're not surprised to see this more utilitarian five-door hatchback showcar here in France. This, despite the fact that Audi already counts similarly proportioned A5 Sportback and A7 Sportback models in its lineup.
Of the TT line extension concepts, this Sportback certainly looks the most production ready, with a bare minimum of showcar tinsel masking realistic proportions and detailing. We think it's quite handsome from stem to stern, even if it's a bit familiar looking. The design incorporates Audi's trademark big-grille look with the TT's prominent arched roofline and heavily radiused fenders, along with a rear lighting graphic that subtly echoes the A3. Despite its leggy looks, the TT Sportback Concept is surprisingly compact, spanning less than a foot longer overall than the production 2016 TT despite its 4.7-inch longer wheelbase and extra set of doors. Those sleek looks come at least partially as the result of an overall height that sits 1.2 inches lower than the TT coupe.
