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.

2017 Audi R8 First Drive

You might think the new Audi R8 is a Lamborghini in a business suit. You'd be wrong; the Huracan is an R8 in a Heinlein shock trooper suit. This is the most raucous, rowdy Audi yet, and it's most certainly a supercar – even when parked next to its bawdier Italian cousin. Although the Huracan has been on the street for nearly a year now, the new R8 and the Lambo were developed in parallel. Audi handled most of the engineering workload, with the Huracan receiving Lamborghini's styling and tuning finesse on top of its Audi-built V10 engine and seven-speed dual-clutch transmission. The R8 gets Audi's motorsports-inspired best. Tally it all up and you have two very different cars built from very similar components. Of course, that could also be said of the R8 and its racing doppelganger, the R8 LMS, the racecar built for WEC endurance racing. That car, in fact, is more closely related to the R8 than is the road-going Huracan – the wheelbases are the same, 50 percent of the parts are shared, and the bodies-in-white are built on the same line. The racecars are pulled off line for occasional tweaks or additions, then slotted back in to run through most of the same workflow as the R8s that will eventually end up on the streets. Like a new pair of your favorite shoes, the new R8 is familiar and foreign at the same time. This development program pulls from the best of a legendary supercar brand's flair for presence and idiosyncrasy. It also takes lessons from the company's customer racing effort, as well as Audi's own impeccable taste in road manners and clean, elegant design. The end result is an inspired supercar with daily-driver comfort and a surprisingly aggressive side. Like a new pair of your favorite shoes, the new R8 is familiar and foreign at the same time. It's more comfortable and compliant on the street, thanks to a new chassis that's 40 percent stiffer, allowing for a more forgiving suspension tune. The completely reworked 5.2-liter V10 engine has a Great White bite to go with its Rottweiler bark, but only after you provoke it from polite mode with a press of either the Drive Select button or the exhaust sound switch. The seats are comfortable – that can be said for both the standard sport seats or optional carbon-shell, race-style buckets. Wrapped in a cabin that's much more futuristic and forward-looking than the last R8, the overall driving experience is refined, luxurious, and high-tech.

The Audi R8 doesn't need turbos to visit Jay Leno's Garage

When Audi launched the original R8 in 2006, it caused a sensation. For its second go at the model, Audi skipped the V8 and went straight for ten-cylinder power in two states of tune: the V10 and the V10 Plus. Of course Jay Leno had the more potent of the two visit his garage. In V10 Plus trim, the Audi makes over 600 horsepower – all from a naturally-aspirated V10 in a segment increasingly dominated by turbocharging. Rivals like the Mercedes-AMG GT, Porsche 911 Turbo, McLaren 570S, and Ferrari 488 have all adopted turbochargers, which makes the R8 something of a modern-day Shelby Cobra, as Leno puts it. See what else he has to say in the video above – and don't forget to watch to the end to see how the launch control works.
