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.

2014 Audi A3 Sedan makes its world debut in NYC

Audi is bringing some excitement to this year's New York Auto Show, showing off a 2014 A3 Sedan that will shortly be vying for attention in the luxury market's newly hot compact segment. The newly minted A3 faces immediate challenge from box-fresh small premium sedans like the Mercedes-Benz CLA and the Acura ILX, as well as players like the Buick Verano and the Lexus CT200h.
Of course, the German automaker will be the first to tell you that this new A3 is more than up to the challenge. Audi's typically high-level of design is in effect here, with sheet metal that is attractive without looking like a clone of the larger A4. The A3 will have the option of full LED headlamps, of course, carrying on Audi's now famous positioning in the world of recognizable lighting. Wheels will range from 16-inches to 18-inches, we're told, which will also help to cement the sporty look and premium placement of the small sedan.

Audi debuts all-new R18 E-Tron Quattro with novel secondary hybrid system

This is the new Audi R18. It looks like the Bond villain of race cars (it has red running lamps), and if Audi's past is any indication, it'll prove difficult to beat in the LMP1 class of the 2014 World Endurance Championship.
The car's full name is the Audi R18 E-Tron Quattro, just like last year's car. Also like last year's car, the new R18 draws its power from a V6 turbodiesel, which powers its rear wheels, and Audi's E-Tron hybrid system, which runs its front axle. Unlike last year's car, though, this R18 has a secondary hybrid system. Audi has fitted the V6 with an electric turbocharger and figured out how to capture waste heat generated when the engine reaches its boost limit. That power can then be stored and fed back into either the turbo or the front axle's hybrid system under acceleration.
There are a number of changes to the body on the new car, forced in large part by series regulation changes. The car is narrower, particularly at the front, but it's also taller. The front end is set off by a new wing, as part of a new WEC regulation. Audi seems quite pleased about this, citing an improvement in front-end downforce and a reduction in cost. Like Formula One, the WEC contenders now have to contend with a ban on the so-called blown diffuser, which forced exhaust gases over the diffuser, creating downforce. That's necessitated some changes from Audi, although as we have no rear shots of the car, we can't tell you what it looks like.
