Porsche would have entered F1 if Audi had blocked its Le Mans program

Go back a few years and you may have heard rumors of Porsche heading into Formula One. That never came to pass - or at least, it hasn't yet - but that doesn't mean that it wasn't close to happening. That's how committed to returning to top-level motorsport competition Porsche has become recently.
Autosport reports that just as Porsche was merging fully into the Volkswagen Group, Zuffenhausen was weighing its options for a factory racing program. Le Mans was its favorite, which makes sense, as it remains far and away the most successful constructor in the history of the famous endurance race. But the strategists at Porsche were worried that its new corporate overlords at Volkswagen wouldn't support two LMP1 programs and would favor Audi, which has positively dominated the modern era of endurance racing, coming second only to Porsche in the number of Le Mans victories it has scored to date.
Porsche's Plan B was reportedly to head into Formula One, although it isn't clear if the German automaker was intent on starting its own team, buying an existing one or merely providing engines to other teams. Porsche fielded its own cars in F1 in the late 1950s and early 60s, and returned as an engine supplier with TAG to power McLaren in the 1980s, powering Niki Lauda and Alain Prost to the World Championship in 1984 and 1985.

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.

Next-gen Audi S7 looking hot in Southern Europe

Development on the next-gen Audi S7 is in full swing. The handsome hatchback is still popular, even if it is starting to show its age, so we have high hopes for the new model. We have some new spy photos of the car performing hot-weather testing in Southern Europe. We don't have many details or a firm release date, but there are a few things we can pull from these pics. The new model looks like it will retain the same general shape as the current one. That's a good thing, as the A7 is one of the best looking vehicles on the market. The long and flowing roof, frameless doors, and long wheelbase all look to be present. There are hints of the Audi R8 from the A-pillar forward while the large grille looks exactly like the on new Audi A8. Many of these design elements are straight off of the Audi Prologue concept from a few years back. Like other Audi S models, the S7 has a wide bumper with large intakes at the bottom corners. A chin spoiler appears to channel air down under the car. Around the side, we can see big wheels and brakes. There are side skirts along the bottom. Out back, it has the requisite quad exhaust tip, a dead giveaway that this is an S model. Lighting both front and rear appears to be LED. What rests under the hood is arguably the car's biggest mystery. We can count on Quattro all-wheel drive and an eight-speed automatic, but we don't know if it will have a turbocharged V6 or V8 under the hood. At this point, both seem equally likely. Horsepower and torque should both be in the mid-400 range while 0-60 mph times should be around 4.5 seconds. Look for more news this fall.
