Audi celebrates diesel milestone with triple-charged RS5 TDI concept

Diesels are typically slower than their gasoline counterparts, but leave it to Audi to turn that notion on its head. After dominating Le Mans and the international endurance racing scene under diesel power for the better part of a decade, the German automaker toyed with the idea of an oil-burning R8 for the road and ultimately made its first performance crossover a diesel. It's made the letters TDI a battle cry, and now it's yelling even louder with the RS5 TDI concept.
Set to be unveiled in a couple of days at the Leipzig Auto Show to celebrate 25 years of the TDI engine, the concept ditches the gasoline-burning 4.2-liter V8 in the production RS5 in favor of a 3.0-liter V6 twin-turbo-diesel with an electric supercharger added on to combat turbo lag. Output comes in at 385 horsepower and 553 pound-feet of torque, which means that while it has 65 fewer horses than the gasoline model, it packs a staggering 236 lb-ft more torque.
The result of the triple-charged madness is a 0-62 time around four seconds flat, trumping the 4.6 seconds for the road-going model. Top speed, of course, is electronically limited to 155 miles per hour, which is a bit of a shame because we bet it'd be a kick to pass a Porsche on the Autobahn in a diesel, now wouldn't it?

The Audi R8 e-tron is dead with less than 100 built

According to a report from Car and Driver, the Audi R8 e-tron is dead (again!) after fewer than 100 examples of the all-electric model were built. This is an anticlimactic end to what could be termed an e-saga, with enough twists and turns to make a Hollywood scriptwriter sit up and start pecking out a screenplay. But here's the important number to keep in mind: 100. That's the production number the R8 e-tron failed to reach. The final tally is less than that, an Audi rep told Car and Driver. And what few were built were sold furtively, and only in Europe, in a strange back-channel in which dealers referred potential buyers right to Audi HQ, says the report. All of these transactions happened without the benefit of an online configurator or any published materials, we understand. That doesn't sound like a recipe for wild success – and neither did the $1,000,000+ pricetag. And this is just the latest stumbling block for the R8 e-tron, which was cancelled the first time back in 2012 when it was still based on the sinister, classic shape of the first-generation R8. If you recall, there was some confusion about the limited run of those first-generation cars, which were initially tipped to be sold to the public. In a strange move, Audi walked that back and held onto the cars for "internal purposes." So it was, until 2015, when we saw the second-generation R8 e-tron in Geneva. Audi promised it'd go on sale in 2015 "upon customer request," which was some foreshadowing to the unusual dealership referral sales model we discussed above. Nonetheless, it seemed like it would be a supremely interesting electric sportscar, with 456 horsepower, 679 pound-feet of torque, a 0-62 mph time of 3.9 seconds, and a range of up to 280 miles. Alas, except for the fewer than 100 European owners who managed to take delivery before Audi yanked the cord, the R8 e-tron's emissionless charms will go unappreciated. We're hoping to get more specific confirmation from Audi about the nature of the cancellation and the exact number produced; until then, stay tuned. Related Video:

Audi to show hydrogen Q6 in Detroit

Audi is allegedly bringing a hydrogen-powered concept to the Motor City next month. The report comes from Autocar, which cites German media in claiming the new concept, tipped to be called the Q6 H-Tron, will ride on the same MLB architecture as the E-Tron Quattro Concept, shown at Frankfurt earlier this year. In fact, it sounds like the Detroit concept will look more or less like the Frankfurt concept, just with low-mounted hydrogen fuel cells instead of battery packs. That said, Audi didn't come right out and tell Autocar that the Q6 H-Tron was coming to Detroit. Instead, a company spokesman told the website that "a concept car with new drive technology" will be shown at next month's show. But this seems like a safe bet. As Audi continues to cope with the fallout of its diesel emissions scandal, shifting focus to an even more alternative fuel source would be a sound strategy, even if it is just a PR move. Whatever Audi ends up showing in Detroit, we'll be live at the show to report on all of it. Look for more in mid January.
