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.

Here's how to follow this weekend's 24 Hours of Le Mans

In the pantheon of motorsports, the 24 Hours of Le Mans stands as one of the great endurance challenges to man and machine. This year's event in France already looks to be one for the ages with Porsche setting record-breaking times in practice and the competition debut of Nissan's front-engine, hybrid racer. Thankfully, there's a massive list of ways to follow this automotive attraction. Reilly Brennan, the Executive Director of the Revs Automotive Research Program at Stanford University, and a friend of Autoblog, has once again assembled a helpful couch-kit to organize many of the options. Unfortunately, the old-school way of just turning on the television might be the most frustrating way to watch Le Mans this year. Fox Sports 1 and 2 are carrying about half the race, but the coverage bounces between them seemingly at random. The broadcast begins on Fox Sports 2 at 8:30 AM Eastern ahead of the 9:00 AM start and lasts there until 12:00 PM. Things don't pick up again until 7:00 PM Eastern on Fox Sports 1 for an hour, and the channels swap back and forth more from there. The Fox Sports Go streaming app offers more, but even it stops showing the race a few times. Thankfully, streaming Le Mans is easy. If you can't dedicate 24-hours on the couch, Radio Le Mans lets you listen to audio commentary anywhere with some of the best announcers in the biz. The Automobile Club de l'Ouest, the governing body for the race, also offers an official video stream in an app for $9.99. For a really low-tech solution, the official Twitter is another choice. Brennan is keeping his list updated with coverage changes. You can also check out and download the spotter's guide (from Nissan) in the gallery above. Enjoy this year's race. If you miss anything, don't worry; expect a full report from Autoblog. In fact, editor-in-chief Mike Austin is attending Le Mans this year, so follow him on Twitter for on-the-fly impressions.

Weekly Recap: Audi pulls back the curtain on its future

The E-Tron Quattro concept is the future of Audi. It embodies all of the traits that will make the brand – and electric-powered luxury vehicles – more relevant into the 2020s. Here's why: The E-Tron Quattro concept, which will debut next month at the Frankfurt Motor Show, is a large sport utility vehicle that promises a range of 311 miles. It's an all-electric daily driver that fits the needs of most Americans. In production – which Audi says starts in 2018 – this vehicle will seat five and likely be called the Q6. You can take your family from Boston to Philadelphia without recharging. That's mainstream. We're moving away from the industry's "science experiment" era (as General Motors product chief Mark Reuss once described the appearance of the first gen-Chevy Volt) to a period where electric vehicles are plausible and practical for many US buyers. The 2018 Q6's only holdup for the masses will be price. But if you can afford an Audi SUV, you'll be able to buy an all-electric version. The E-Tron concept uses Volkswagen Group's second-generation modular longitudinal platform. The lithium-ion battery is located between the axles and below the cabin. Urquhart says the production model will feature the automaker's latest battery technology developed with LG Chem and Samsung. IHS Automotive projects the Q6 will sell more than 40,000 units annually by the end of the decade. "The E-Tron Quattro is a precursor for what will be an exciting and landmark production model for Audi and will position the brand at the forefront of the premium EV market," IHS analyst Tim Urquhart wrote in a commentary. It's the Tesla-zation of America. It's the Tesla-zation of America. The Q6 will be a Model X fighter, and expect other automakers to follow suit, particularly in the luxury sector with SUVs and other large vehicles. They offer more space for the battery packs, and development costs can be recovered easier. "Premium brands have an inbuilt advantage in terms of introducing [electric] powertrains over more mainstream automotive brands," Urquhart wrote. OTHER NEWS & NOTES Analyst says Tesla stock could be worth $465 a share Morgan Stanley analyst Adam Jonas sent shockwaves through the industry when he said Tesla stock has the potential to reach a whopping $465 a share. That's a leap from its $230.77 price at Friday's market close.
