Watch the Le Mans Audi R8 safety car drift during red flag

With open-wheel, prototype, and GT cars so dependent on keeping their tires warm, European series enlist much higher-performance cars than the family sedans that pace the NASCAR field. That also means their drivers need to know their way around a race track. Yannick Dalmas, the driver of the 24 Hours of Le Mans' Audi R8 safety car, proved that point during heavy rains yesterday. The four-time Le Mans champ and former F1 driver had a bit of a moment during the red flag. We don't know if Dalmas was having a bit of fun or genuinely getting out of trouble on the deluged track, but cameras caught him executing an lurid drift that will probably end up in an Audi commercial in the near future. It's hard to tell what section of the track Dalmas went drifting at – it's pitch black in the video – but based on the downward, right-hand bend, we're guessing it was between Tertre Rouge and the start-finish line, maybe in the Esses. You can see the big moment in the video, which generated plenty of cheers from the red-flagged racers and their pit crews. Stick around for the end of the video for Porsche driver Mark Webber's impressed reaction.

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.

Suspended VW exec Hackenberg resigns in wake of scandal

Ulrich Hackenberg, father of the innovative modular architecture that underpins many modern Volkswagen and Audi products and a 30 year veteran of the giant company, has resigned his position as the lead engineer for the entire Volkswagen Group as well as his seat on Audi's management board, reports Automotive News. The resignation closes out a two-month suspension while the investigation into VW's deceptive emissions practices continues.The resignation follows the admission by Audi that the 3.0-liter TDI V6 engine was also fitted with emissions-control defeating software, like some of its four-cylinder TDI counterparts. In turn, this lead to changes in Audi's management structure. AN reports that Matthias Muller, who has already taken over Martin Winterkorn's position as VW Group CEO, will also be named chairman of the Audi brand.Hackenberg's successor was named as part of this announcement. Stephan Knirsch, who has lead engine development at the Audi division, will assume Hackenberg's roles as both board member for Audi in charge of technical development, and as the head for technical development across the whole group.Related Video:
