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.

The 2013 Rolex 24-hour race at Daytona comes down to the last hour [spoilers, w/video]

It took 24 hours to run the race, but it was the last one was stuffed with the high action as four cars were still trying to figure out how to gain victory on the track and in the pits. Along with the obligatory crashes, spins, mechanical issues and retirements had come numerous penalties, a double-digit number of full-course yellows and two hours of fog that turned early Sunday morning into a stretch of parade laps.
The final hour would make up for the morning - drivers who might have been happy just to get on the podium had a shot at victory as the end of the race approached, and that turned into a few gambles that paid off, and at least one that didn't...

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.
