Audi A3 G-Tron offers big range, few emissions

Audi is exploring a variety of sustainable transportation technologies beyond the traditional diesel, hybrid, plug-in and electric options, including the compressed natural gas A3 Sportback G-Tron that debuted today at the Geneva Motor Show.
The most interesting thing about this rather innocuous-looking A3 Sportback is that when run on Audi e-gas, the car becomes completely carbon neutral, emitting no more CO2 than was chemically input in this special fuel's production. Audi has already broken ground on a new plant - powered by renewable energy, of course - that uses electrolysis to produce e-gas, which could then be made available through any natural gas distribution network.

2015 Audi RS5 Coupe Sport is one of 75

Audi has released a new limited edition of its V8-powered RS5, with the 2015 Sport edition. Limited to just 75 units and designed by the German manufacturers Exclusive customization team, the stylish RS5 starts at $87,575. That's nearly $17,000 more than the standard RS5, although you might struggle to see why. The Sport adds beautiful 20-inch 5-V-spke wheels, along with plenty of nice leatherwork in the cabin. That includes the black-and-Crimson-Red Nappa leather seats, which feature an embossed RS logo in the seatback, as well as Crimson Red leather door inserts. Contrast stitching in the leather-wrapped wheel and shifter boot match the shade on the seats and door inserts. Audi will paint the limited-edition RS5 in either Daytona Gray or Nardo Gray for no charge or, if you're willing to pay a bit more, you can chose from one of the shades from the manufacturer's Exclusive catalog. There's no mention of how much these custom hues will cost, though. Beyond that, the RS5 Sport is the same thumper that's been on sale for several years, with a 4.2-liter, 450-horsepower V8 under the hood and a seven-speed, S-Tronic transmission dispatching power to a Quattro all-wheel-drive system.

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.
