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.

2018 Kia Stinger vs. other luxury hatchbacks compared by the numbers

Ten years ago, if you had told us that one of the many new luxury segments to develop would be sedan-style hatchbacks, we'd have said you'd lost your mind. And yet, here we are today with not one, but four cars competing in just such a niche upscale segment: The Kia Stinger, Buick Regal Sportback, BMW 3 Series Gran Turismo and Audi A5. That's just in one size and price bracket. Two of the manufacturers listed here make larger versions of each luxury hatchback. We aren't entirely sure how it happened, but we're not going to complain, because we love the idea of a car with almost no compromise: luxury features, sporty performance, and plenty of practicality. Try Autoblog' s Car Finder to search for your next new vehicle. One of the reasons we're taking a look at these cars right now is that Kia has recently released pricing for its entry in the segment, the Stinger and Stinger GT. Buick wasn't far behind with the Regal Sportback and Regal GS, nor was Audi with the A5 and S5. So it seemed like an appropriate moment to look at the numbers and see which come out ahead or behind, with victors in each category highlighted with bold and underlined text. What we found when comparing these cars' statistics is that each one has a clear area of expertise. For performance, it's hard to beat the four-cylinder Kia Stinger and the V6 Stinger GT. The four-banger has the most horsepower of the four cars, and is just behind on torque. The V6 has the most power and torque among the six-cylinder versions. The Stingers are also the second lightest of the group when equipped with rear-wheel drive, though they fall to third with all-wheel drive. Space is a split between the Buick Regals and BMW 3 Series Gran Turismos. The Buicks have the most cargo space with the rear seats up or folded by a significant margin. The BMW on the other hand generally offers more space for passengers. It's up to you what's most important. Compare these and other potential new vehicle purchases using our tool. When it comes to cost, nothing can beat the four-cylinder Regal's base price of under $26,000. But if a V6 is what you're after, the Stinger GT is the cheapest. Neither matches the Audi A5 and S5 for fuel economy, though. Both Audis have the highest numbers for city, highway, and combined EPA estimates. Related Video:

Audi E-Tron Sportback Concept previews 2019 production model

Audi has revealed the E-Tron Sportback concept it has been teasing ahead of Auto Shanghai. The all-electric model, the automaker says, previews a production model slated for 2019. Audi will launch an electric SUV with a driving range of 311 miles in 2018. "Following close on its heels, in 2019," says Audi Chairman Rupert Stadler, "comes the production version of the Audi E-Tron Sportback – an emotional coupe version that is thrillingly identifiable as an electric car at the very first glance." The E-Tron Sportback is powered by three electric motors – one on the front axle, and two on the rear ­– providing a total 320 kW (429 horsepower), with a boost mode that ups that output to 370 kW (496 hp). It's capable of a 0-62 mile per hour sprint of 4.5 seconds. A liquid-cooled 95-kWh lithium-ion battery provides 311 miles of driving range (on the European cycle). The concept features Audi's singleframe grille, with an illuminated four-ring logo. The front of the car is shaped for optimal airflow, and the dip in the hood also gives it a uniquely sporty look. Its front fascia integrates lighting that not only illuminates the road, but can project animations or provide communicative signals to other drivers or pedestrians. Its 23-inch wheels are imposing, giving the car a muscular stance. Side mirrors are replaced by slender cameras, which improve airflow and provide a better view of the car's surroundings, helping to eliminate blind spots. By revealing the E-Tron Sportback concept in China, Audi is acknowledging the significance of the country's electric vehicle market. "There are already about 150,000 charging stations in the country, with another 100,000 due to come on stream by the end of 2017," notes Audi Board Member for Marketing and Sales, Dr. Dietmar Voggenreiter. "We are well equipped for this rapid growth. In the next five years we will be offering five E-Tron models in China, including purely battery-powered vehicles with ranges well in excess of 500 kilometers (310.7 miles) such as the Audi E-Tron Sportback."
