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.

Recharge Wrap-up: Atieva making EV with former Tesla talent, Holland lowers PHEV incentives

A reduction of tax incentives on company cars in Holland is expected to put the brakes on plug-in hybrid sales. Cars are taxed at an average of 25 percent, with plug-in hybrids taxed at just seven or 14 percent, depending on emissions. Taxes on PHEV company cars will increase to 14 and 21 percent. With company car leases making up a third of vehicle sales in 2014, the uptake on PHEVs "will likely go back to regular volumes," according to Volvo's Christiaan Krouwel. It could be a boon for battery electric cars, as their tax rate will remain at four percent for company cars. Read more at Automotive News Europe. Ford is testing cylinder deactivation in its 1.0-liter EcoBoost engine. On-road prototype testing has shown improvements in fuel economy of as much as six percent. Ford engineers developed a system using a new dual mass flywheel, pendulum absorber, and tuned clutch disc to allow cylinder deactivation under a wider range of speed and engine loads with less NVH. "The highest priority in the development of new combustion engines for automotive applications is the ongoing reduction of fuel consumption," says Ford's Andreas Schamel, presenting Ford's findings to the Vienna Motor Symposium.

The Silicon Valley-based startup was founded in 2007 by a former Tesla vice president, and its roster includes 12 other former Tesla employees. Already well funded, Atieva is now looking to fill its ranks with more talent, with 32 engineering positions, two recruiter positions and other job openings posted at its website. As for the EV it is working on, Atieva says it is "redefining what a car can be, by building an iconic new vehicle from the ground up." Read more at Charged EVs. Testing shows that Joule ethanol, made from recycled CO2, meets standards for use in the US and Europe. In partnership with Audi, Joule has been working toward making its recycled CO2 fuels ready for commercialization. "We are pleased to achieve another critical step towards our planned near-term delivery of fuel-grade ethanol from recycled CO2," says Joule President and CEO Serge Tchuruk. "Using waste CO2 as a feedstock, our technology has the two-fold advantage of reducing greenhouse gas emissions and producing cost-competitive, drop-in fuels." Joule will use these test results to get government approval for the use of its ethanol in highway fuel.

Notes from day one of the Rolex 24 at Daytona

We came to Daytona Beach, Florida where you can drive on the beach, gun shops outnumber doughnut shops and you can putt-putt and fish for alligators at the same place. But we're not here for any of that - we've made the trip with Audi in order to experience the Rolex 24 at Daytona, the first race in the 2013 Grand-Am season and the only 24-hour race in America.
Three teams are racing four Audi R8 Grand-Am cars - WeatherTech Racing, Rum Bum Racing and APR, which is running two cars. Shown to the world two years ago, the R8 Grand-Am is part of Audi Sport's R8 LMS customer racing program that was commenced in 2008, and ever since 2009 has been nabbing success all over the world: In four years it has taken 154 victories and 17 series titles. That is with less than 100 cars sold to customers throughout the world, and the trophies - either class wins or overall victories - have been gathered from all of the major endurance races except one: Daytona.
