Next Audi R8 to eschew engine downsizing, go on diet instead

Looking across the Audi landscape, many models that used to get the company's high-revving, naturally aspirated 4.2-liter V8 are now powered by smaller, yet similarly powerful, forced-induction engines. From what Auto Express is reporting, though, the next-generation Audi R8 will not meet this same fate.
Rather than ditching its V8 and V10 powerplants, the next-gen R8 - expected to debut in 2015 - will shed pounds from its curb weight. The 2014 R8 currently weighs between 3,583 pounds and up to 3,957 pounds, but the report says that engineers are targeting a weight of less than 3,300 pounds. All models will get cylinder deactivation, which along with lower curb weights should help to improve fuel economy and emissions. Head on over to Auto Express for more reported information as well as a handful of renderings that take a stab at how the next R8 may look.

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 service tech joyrides customer car, allegedly takes drugs on the way [UPDATE]

UPDATE: We've received and added an official statement from Audi Palo Alto. Dealerships get a bad rap. Stories about sleazy salespeople and overpriced service procedures abound, even though the reality is that most dealers are run by and employ honest, fair folks. But just because the bulk of dealers and their employees are good people, it doesn't mean some bad eggs won't slip through the cracks. Audi Palo Alto, in the heart of Silicon Valley, is finding this out the hard way after dash cam video of a service tech abusing a customer's car started blowing up on YouTube. In the video, which you can watch above, the unnamed service tech took YouTube user Carrera Chris's Audi – it's not clear what model, but it sounds like one of the company's higher-performance 3.0-liter, supercharged V6 models – for a rather spirited test drive. There are plenty of wide-open-throttle runs mixed in with some speeding – the dash cam's lower display shows 90 miles per hour at one point on the freeway – and you can hear the driver laughing throughout. None of this is too remarkable on its own, and maybe not enough to get the tech fired. Until, that is, he pulls into a parking lot and begins snorting something. The dash cam doesn't show the technician, so it's impossible to determine what substance – if any – the driver is allegedly taking. It could be coke, could be crushed up pills, or, hey, it could be a prescription nasal spray (it is allergy season, even in perpetually lovely northern California). Carrera Chris does say he found white powder in the seams of the driver's seat, so take that for what it's worth. There are five videos that include 12 minutes of footage – the one up top is a summary, while the four below show the alleged drug use and some more mundane footage. We've reached out to Audi Palo Alto's general manager, Jason Mattia. He wouldn't answer our questions over the phone, but did forward an official statement from the dealer. An unfortunate incident was brought to our attention earlier this week. We immediately began our investigation and have already taken action. We are working with the customer involved and have thanked them for bringing this matter to our attention. At Audi Palo Alto, we are proud to be a part of the San Jose community. We value and respect our customers, and our team of 75 employees strives to deliver the highest level of customer service.
