Audi S5 spied

We only recently saw the next-gen Audi A5 testing for the first time with its sleeker design covered in camouflage. Now, here's a well-concealed glimpse at of the higher-performance S5 for comparison against the standard coupe. With so much swirling camouflage picking out the differences between the two models isn't easy, but there are a few tweaks to notice. The intakes on the front fascia are just a little bigger, hinting at the increase in power. The brakes also appear to be larger, especially when comparing them at the rear. Of course, the most obvious changes are the dual exhausts poking out each corner of the speculative S5. While more power is assured for the S5 over the A5, the exact powerplant isn't officially known yet. Rumors suggest Audi using a tuned version of the supercharged 3.0-liter V6 making between 340 horsepower and 350 hp, at least for the S4. The switch to the MLB Evo platform means less weight to haul around no matter what's under the hood, though. The next-gen A4 should provide some more hints about the future of the lineup when it launches at the Frankfurt Motor Show in September, and the coupes are expected to join the lineup later.

Audi mulling producing version of Quattro showcar, just not sure which one [w/poll]

Head of design for Audi, Wolfgang Egger, has told Auto Express that a reborn Quattro could enter production, but bosses for the company haven't yet decided whether to base it on the Sport Quattro concept that just debuted at this week's Frankfurt Motor Show or the smaller Quattro concept that was revealed at the 2010 Paris Motor Show.
While both draw their inspiration from the original Ur-Quattro of the 1980s, they vary wildly in both size and choice of powertrain. The 2010 Quattro concept was based on Volkswagen's MQB platform, shared with such vehicles as the Golf and Audi A3. The Sport Quattro, meanwhile, was built atop the company's larger MLB platform that's used almost exclusively for Audi models, including the A5, which is also a coupe.
Under their hoods, the 2010 Quattro concept simply employs a version of the same 2.5-liter engine used in the TT RS, tuned to deliver 408 horsepower, while the Sport Quattro goes nuclear with a twin-turbo V8 hybrid powertrain that develops 700 hp and 590 pound-feet of torque. Both, of course, employ quattro all-wheel drive just like their forebearer.

Is the Audi R8 E-Tron project back on again?

If you ask Audi about its R8 E-Tron prototype, the all-electric two-seater that was first shown at the 2009 Frankfurt Motor Show, the automaker will tell you that its development program is on hold. Yet, as we reported in January, limited production of the combustion-free coupe may be moving forward... information still officially unconfirmed by the automaker.
New images of the electrified R8 undergoing winter testing in Europe have emerged (above and in our gallery), and the car has been spotted running in Spain as well. Both sightings support reports that the E-Tron, with its 150-mile battery range and 8:09 Nürburgring time, may be back in business. Does the program have a green light, or is Audi merely trying to take some of the thunder from the BMW i8?
Whatever the case, if the R8 E-Tron does eventually make it into showrooms - and we are now led to believe it will - expect production volume to be very low. Assuming it doesn't get shelved again, of course.
