2014 Audi RS7 [w/video]

Stunning Sportback Gets The Performance To Match
Saying the 2014 Audi RS7 Sportback is not as good as the not-for-North-America Audi RS6 Avant we recently tested is a bit like saying one more strip of crispy bacon would make our Waffle House All-Star Special breakfast even more special. The RS7 goes to ten while the RS6 goes to eleven, maybe, but they both rock our world. The RS7 is meant for the far wider buying audience worldwide, not just for western European family bombing runs, as with the RS6 Avant.
But, hey, this RS7 simply hurtles down the road in a singularly sexy way. And if you really want this bodystyle - and who could blame you? - the RS6 Avant doesn't really even matter anyway. After a full day on perfect dry and warm Swabian two-lanes driving this Audi very hard, we barely thought about it at all.

Audi unveils A3 Sportback G-Tron with bi-fuel power, 808-mile range

By this time next year, the Audi A3 Sportback will be offered with a variety fuel-efficient powertrains ranging from diesel to the all-electric E-Tron, but perhaps the most interesting is the all-new G-Tron model, which uses Audi's innovative carbon-natural compressed natural gas called e-gas. Previously called A3 TCNG, we first heard about this technology last year, but now Audi has confirmed that this low-emission, sustainable-fuel will debut by the end of this year on the A3 Sportback G-Tron.
To create this e-gas, a plant in Werlte, Germany uses electricity to split water into hydrogen and oxygen. As hydrogen fuel cell vehicles become more popular, Audi says that this process could also be used to produce hydrogen fuel, but to create CNG, it mixes the hydrogen with carbon dioxide to create "synthetic methane." Since it is identical to the CNG available today, Audi's e-gas can be shipped and stored using the existing CNG infrastructure. Making the whole process even greener, Audi obtains the CO2 for this process from a nearby biogas plant, which would otherwise be released into the atmosphere.
Differentiated from the regular versions of the A3, the G-Tron features a pair of tanks under the rear cargo floor holding 15.43 pounds of CNG, which can power the car for almost 250 miles. What's more, the A3's conventional gasoline tank is still in place, giving the car an addition 560 miles of range. In total, that means the A3 G-Tron has a driving range of more than 800 miles. To run on both CNG and gas, Audi made changes to the car's 1.4-liter four-cylinder engine (including the turbo, cylinder head and fuel injection system) and catalytic converter.

Spyker C8 Aileron to come back with supercharged power?

The new B6 Venator wasn't the only vehicle on display at the Spyker booth at the 2013 Geneva Motor Show. The company still has its C8 Aileron on offer, and Road & Track has word of a potential powerplant upgrade for the long-running machine.
Since its introduction in the year 2000, the C8 has used a 4.2-liter V8 engine sourced from Audi, which, in base form, offers up 400 horsepower. Though it's a great powerpant, that's simply not enough power in this day and age - after all, if a car is going to be called super, it needs to offer more ponies than something as mundane as the Ford Mustang GT.
According to R&T, John Walton, Chief Commercial Officer at Spyker, indicated that a new engine supplier may be in the works. "[The Audi-sourced V8] really hasn't got enough bang for the buck. To be honest, every supercar needs to have something that begins with a '5' today. That's why we're supercharging the car in the future, which will take it to over 500-hp," said Walton.
