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.

Audi Sport plots ambitious growth for RS lineup

Audi Sport is set to double its range of high-performance, RS-badged vehicles, reports Autocar. In an interview, Stephan Winkelmann, head of Audi Sport, revealed plans to add eight RS models to its lineup by early 2018. Winkelmann didn't reveal which vehicles would get the RS treatment, but said that "it is better to under-promise and over-deliver." Audi has several RS-badged cars, including the RS7, RS6 Avant, TT RS (both in its hard-top and soft-top variant), RS Q3, and RS3 (some of which are sold in the US). Autocar believes that the A1, A4, and Q5, along with the R8 are next in line to get the RS treatment in some markets. With Mercedes-AMG selling more vehicles, 80,000 units over the past few years, according to Autocar, it makes sense for Audi Sport to follow closely behind with a similar idea. While Mercedes is placing the AMG badge on its vehicles to bridge the gap between its high-performance and lower end models, Audi Sport says it's taking a different tactic. "We are not going to do what they do," Winkelmann said. Even without the extra vehicles, Audi RS sales could top 20,000 units this year, reports Autocar, with Winkelmann stating that the brand would experience "double-digit growth this year." Hopefully, Audi Sport's decision to add more RS models will result in some of those high-performance cars coming to the US.

Audi R8 V10 gets tuned up by ABT

Bavarian tuners ABT have done another job on the Audi R8 V10, pumping up the 5.2-liter FSI V10 from 525 horsepower to 600 hp, and torque from 391 pound-feet to 406 lb-ft. With 50 more horsepower than the R8 V10 Plus - but not the extreme weight-loss scheme - ABT claims a 0-62 mile per hour run of 3.5 seconds, the same as the R8 V10 Plus, and a top speed for the mid-engined coupe of 198 miles per hour "is no problem at all."
Managing all that speed are the aero tweaks provided by a comprehensive body kit including a rear wing, a lowered and beefed-up suspension, a stainless steel exhaust and 19-inch wheels in two different designs.
The press release below has a few more bits of info on the matter. And while ABT hasn't put a price on the Audi upgrades, but it's safe to say that nearly 200 mph in an R8 won't come cheap.
