Audi testing long-tail version of R18 e-tron quattro for Le Mans

Race teams are always looking for ways to shave hundredths of seconds of their lap times. Case in point: Audi is making some slight changes to its prototype racecar to make it ever so much more slippery as it cuts through the air.
Debuting at the second round of the FIA World Endurance Championship at Spa on May 4, Audi will be testing a long-tail version of its R18 E-tron Quattro racecar. As its name suggests, the long-tail car gets a lengthened rear section with the goal of improving aerodynamics. The long-tail will be run alongside the standard version of the racecar as a testbed for possible changes that might be in store, heading into the 24 Hours of Le Mans.
Audi did not say how many inches were added to the racecar, but as you can see in the image above, "long-tail" definitely doesn't take on the same meaning of classic long-tail cars of the past such as the Porsche 917. More information about the car, Audi's team and even some info about the track itself can be found below.

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.

A dealer made a 'Urus' out of an Audi Q7 to get people excited for Lambo's SUV

Fake news seems to be catching on. In an attempt to drum up some interest in the upcoming Lamborghini Urus (the Italian SUV that hasn't been unveiled yet) the Lamborghini dealer in Nurnberg, Germany, created a Lambo-badged promotional vehicle. It seems it has fooled at least a few folks, with several outlets reporting on it as if it's a Lamborghini prototype. Of course, it's not. What you're looking at is an Audi Q7 with a camouflage wrap that includes a Lamborghini-script logo across the back and a promotional message on the side, which reads: "Der Urus kommt / Lamborghini Nurnberg." Thanks to one semester of German, we can tell you that first part means "The Urus is coming." Note, that's "is coming," not "is here." There's also something that kind of resembles a scoop on the front fender. It's also fake. It's not uncommon for automakers to put a cryptic message on the side of a test car, often with swirly camo, but this takes the idea a step further since it's not the actual car underneath. That said, the production Urus, whenever it arrives, is expected to share the Audi Q7's MLB 2 platform. So it sort of works. Kind of.
