Watch the Audi R18 E-Tron Quattro long-tail testing at Monza

Audi released a single photo of the long-tailed version of its R18 E-Tron Quattro Le Mans racer, but the photo didn't offer the best view of the stretched rear. The car has been caught testing at Monza, in Italy, and not only do we get a better view of what it's got out back, we get pretty awesome sound as it makes high-speed runs past the camera.
Since the 2013-spec car was found to be down on performance versus the 2012, the long-tail is a different evolution to see if Audi can eke out more performance from its already dominant chassis. Have a look and a listen in the video below.

Audi S3 starts at $41,400, A3 Cabrio rings up at $35,600 and A3 TDI priced from $32,600

Audi has released the official pricing info for the all-new A3 TDI Sedan, A3 Cabriolet and the S3 Sedan, and the news appears pretty good all around. As usual, none of the following prices include Audi's unspecified-for-now destination charges.
The big news is the S3, complete with 292 horsepower, a six-speed dual-clutch transmission and Quattro all-wheel drive. Prices start at just $41,100, which is a decent savings over the more powerful, 355-hp Mercedes-Benz CLA45 AMG.
The new A3 TDI sedan, meanwhile, has a starting price of just $32,600. While you'll be certain to save some money on fuel, you'll be doing so without Quattro all-wheel drive. Still, the improved economy of the 2.0-liter, turbodiesel four-cylinder isn't priced too steeply, relative to the gas-powered A3's $29,900 starting price.

Is Audi readying hardcore final edition R8?

The days may be numbered on the current Audi R8, but if our latest round of spy photos is any indication, Audi's first supercar is going to go out with a bang. This camo'd tester was spotted parked somewhere in Europe, and if doesn't at least belie a faster R8, it certainly indicates that a more aerodynamically intense model is coming.
The tall rear wing is the most obvious aerodynamic change. It's joined out back by a none-too-subtle diffuser and the cannon-like exhausts of the R8 V10 Plus, while the front and side of this particular R8 are home to new side sills and winglets on the lower front fascia.
We'll be keeping our ears to the ground for any more on what looks to be another variation of first-generation Audi supercar. Until then, let us know what you think this car may foreshadow. A new halo model? A gentleman racer? Have your say below.
