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 also calling in A8, S8 over sunroof issue

The S6 and S7 (apparently prone to potential fuel leaks) aren't the only Audis being recalled currently, as a separate recall notice has been issued for its flagship A8 luxury sedan and its high-performance counterpart, the S8.
The problem apparently revolves around the glass sunroof, which is fitted as standard and which is reportedly prone to break. The National Highway Traffic Safety Administration determined that not only could the falling shards themselves end up injuring the vehicle's occupants, but could also distract the driver enough to cause a crash. As a result, Audi's American wing is bringing in all 2013 and 2014 model year A8s and S8s - 1,120 units in all - to have their glass sunroofs replaced free of charge.

2015 Audi RS7 Dynamic Edition is a pretty car for a pretty penny

Making its world debut at the New York Auto Show, and commanding a $40,250 premium over the base RS7, is Audi's new 2015 RS7 Dynamic Edition that arrives with an MSRP of $146,045 (including destination and delivery). The range-topping hatchback is designed to showcase Audi's exclusive program, which allows customers to choose choose from the automaker's long list of options and then take the customization one step further with bespoke paintwork, upholstery, bodywork and wheels.
The interior features Black Valcona leather seats with Crimson Red honeycomb stitching, and matching Crimson Red seat belts. The contrasting color is carried through to the stitching on the dashboard, center armrest, door panels, shift boot and center console. Carbon fiber inlays provide additional contrast. The exterior is offering in four colors (Ibis White, Suzuka Gray metallic, Daytona Gray pearl and Phantom Black pearl), with each arriving with performance-oriented DRC suspension (with three-stage adjustable dampers), 21-inch Gloss Black wheels, Tornado Red painted brake calipers and sport exhaust. A carbon fiber front splitter, rear diffuser and carbon fiber engine cover complete the package.
Like the standard RS7, the Dynamic Edition arrives with a twin-turbocharged 4.0-liter V8 rated at 560 horsepower and 516 pound-feet of torque. With an eight-speed automatic transmission, running through Audi's Quattro permanent all-wheel drive and a sport differential, the four-passenger vehicle will crack the 60 mph acceleration benchmark in a reported 3.7 seconds - and, thanks to cylinder-on-demand technology, it avoids a gas-guzzler tax. The RS7 Dynamic Edition arrives at dealerships in early summer.
