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 unveil S1 hot hatch at Geneva Motor Show

Audi has been toying with the idea of a hot hatch based on the A1 premium city car for some time now. It rolled out the 500-horsepower A1 Clubsport Quattro concept at the Wörthersee gathering a couple of years ago, then put its form (with half the power) into limited production with the 252hp A1 Quattro (pictured above) shortly thereafter. What it hasn't done is offer a mainstream S1 that people can actually get their hands on, but that's all about to change.
Following spy shots of numerous prototypes, Auto Express claims to have it on good authority that the new S1 will be unveiled at the upcoming Geneva Motor Show in March. Though likely less aggressive in its visual impact, the S1 is expected to get almost as much power as the aforementioned A1 Quattro, with a 2.0-liter turbo 4-cylinder sourced from the larger S3 but detuned to 230 hp.
A six-speed dual-clutch transmission is expected to drive all four wheels - something for which the platform was not originally designed but was later adapted to accommodate - though the availability of a six-speed manual remains in question. Unfortunately the A1 was never destined for the North American market, so as much as we might want one (and as much as Ingolstadt may be motivated to take a bite out of the Mini market), we wouldn't expect to see it roaring into American showrooms.

Audi A6 gets styling, powertrain tweaks

The Audi A6 is already a fairly handsome, German luxury sedan, but the whole range is receiving some styling updates in Europe this fall. Audi's US arm would not directly confirm which of these updates will be coming to America, instead just telling us that an updated A6 will be coming next year.
On the outside, the tweaks are fairly minor. The company's single-frame grille, which shows up throughout the model lineup, gets some very subtle styling changes, and the lower bumper and its air intakes are also reshaped. More obviously, the headlights have a new form with the LED running lights cutting through them in roughly the shape of a T, as opposed to outlining them, as before. A similar shape is also used for the updated taillights, and there are now rectangular exhaust outlets around back, as well. In profile, the side sills also get a harder crease toward the rear of the sedan.
Inside, things are kept generally the same, as well. There's a new Flint Gray interior color for the A6 and Salsa Red for the S6. But the biggest change is a power-retracting eight-inch infotainment system using the Nvidia Tegra 30 graphics chip. The optional night vision assist system is also improved with new functions, according to Audi.
