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 R18 suffers huge crash during Le Mans practice, driver conscious and alert

Loic Duval, driver of the #1 Audi R18 E-tron Quattro, suffered a massive crash today during free practice for the 24 Hours of Le Mans. Duval's car reportedly went off track backwards at high speed near the Porsche Curves and flew into the retaining fence. There is no video of the actual crash at the moment, but a video of the aftermath (viewable below) shows significant damage to the Audi and to the fence. The wall nearby the car appears unaffected.
Thankfully, it occurred quite close to a marshal's stand, and they were present almost immediately after the incident. Both the official press release from the 24 Hours of Le Mans and a tweet from Audi Sport (below) indicated that Duval was conscious after the crash, and he was taken by ambulance to the medical center and then to the hospital. The press release says: "His condition is encouraging." However, any injuries he might have sustained are unknown at this time. After the crash, the course was red flagged, and practice resumed about 50 minutes later.
Duval is alert. He will be transported from the Medical Center to the hospital for further examinations #R18 #LM24 @FIAWEC @24hoursoflemans

Audi readying diesel PHEV models for US and Europe

With the racing pedigree provided by the Audi R18 E-Tron Quattro, you'd be forgiven for thinking that the German king of Le Mans is capitalizing on the connection between its road cars and race cars at every opportunity. Maybe there's an entire range of Le Mans Editions for the automakers diesel-hybrid offerings, with perhaps Tom Kristensen acting as the brand's spokesperson for the technology in Europe. You'd be wrong, though, because despite the R18's overwhelming successes in endurance racing, Audi the road-car manufacturer doesn't offer a single diesel-hybrid production car.
This factoid will hopefully be as short lived as it is disappointing, though, as a diesel-electric is around the corner, according to the brand's tech boss, Ulrich Hackenberg. In fact, it gets better than a mere diesel-hybrid; it will be a plug-in diesel-hybrid, only the second to hit the market, alongside the European-market Volvo V60.
According to Hackenberg, the new tech will be the result of a marriage between the brand's well-received 3.0-liter, TDI V6 with an electric motor. The next-generation Audi Q7 (shown above) will be the initial recipient, confirming previous reports that claimed a PHEV TDI could come to the next-gen CUV. Its MLB architecture, meanwhile, would allow the plug-in-hybrid-diesel powertrain to be fitted easily enough to the A8 luxury sedan. While the new Q7 should hit the market at some point in 2015, it's unclear when the PHEV TDI model could see the light of day.
