Audi testing long-tail version of R18 e-tron quattro for Le Mans

Race teams are always looking for ways to shave hundredths of seconds of their lap times. Case in point: Audi is making some slight changes to its prototype racecar to make it ever so much more slippery as it cuts through the air.
Debuting at the second round of the FIA World Endurance Championship at Spa on May 4, Audi will be testing a long-tail version of its R18 E-tron Quattro racecar. As its name suggests, the long-tail car gets a lengthened rear section with the goal of improving aerodynamics. The long-tail will be run alongside the standard version of the racecar as a testbed for possible changes that might be in store, heading into the 24 Hours of Le Mans.
Audi did not say how many inches were added to the racecar, but as you can see in the image above, "long-tail" definitely doesn't take on the same meaning of classic long-tail cars of the past such as the Porsche 917. More information about the car, Audi's team and even some info about the track itself can be found below.

BMW says SUVs killed the sports car market

In many ways, we're living in a golden age of automotive performance. After all, it's possible to show up at a Dodge dealer, hand over about $60,000 and storm away with a 707-horsepower Challenger Hellcat. Or for those who prefer a touch more luxury, the BMW M4, Mercedes-AMG C63 and latest Cadillac ATS-V offer between 425 and 503 horsepower, depending on your pick, with a bit more poshness. However, none of these powerful vehicles fit the classic definition of a two-place, droptop sports car, and according BMW head of sales Ian Robertson, that's because the segment is very much in the doldrums.
According to Robertson, two factors seriously wounded the classic sports car market. First, the global economic crisis of a few years ago put a serious hurt on sales, according to Bloomberg. Further worsening the situation, the boom in popularity of luxury SUVs and crossovers in the past few years hasn't allowed for much recovery. Even car-hungry China hasn't helped much because of the smog in many cities and preference among some of the very rich there to be chauffeured.
Combined, Audi TT, BMW Z4 and Mercedes-Benz SLK sales peaked around 114,000 units a year in 2007, but they are only expected to reach 72,000 annually by the end of the decade. Robertson is pretty pessimistic about the market's comeback too. "Post-2008, it just collapsed. I'm not so sure it'll ever fully recover," he said to Bloomberg.

2016 Audi S8 Plus burns the 'bahn faster

At no point during my drive of the Audi S8 last year did I think, "You know, this car could really use more power." With 520 horses on tap from a twin-turbo, 4.0-liter V8, the S8 is a damn good luxury/sport sedan. But I'm certainly not going to complain about a big ol' power boost, and that's just what we have here with the new Audi S8 Plus. It's got the same engine underhood, but power is boosted from 520 hp and 481 pound-feet of torque to a healthy 605 hp and 516 lb-ft. There's even an overboost function that increases torque output to 553 lb-ft for short bursts. That means the big S8 will run to 60 miles per hour in just over three and a half seconds. Hot damn. All that thrust doesn't come cheap, though; the S8 Plus costs $115,825. Of course, that's cheaper than the Mercedes-AMG S63 sedan, but the Merc is a decidedly more luxurious car. Still, a 605-hp S8 sounds mighty fine to me. Of course, a 520-hp S8 was already perfectly fine to begin with.
