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.

Bonhams sells '85 Audi Sport Quattro for record $427k at Goodwood

1960s Ferraris and pre-war Bugattis tend to fetch the highest prices at auction, but the Audi Sport Quattro is coming into its own. Just this past January in Scottsdale, RM Auctions sold one for an investment-worthy $401k. But during its sale at the Goodwood Members' Meeting this past weekend, rival auction house Bonhams set a new record for the prototypical hot hatch at GBP287,100 – equivalent at today's exchange rates to over $427,000. The pristine white 1985 example has had three owners to date and 26,000 miles on the odometer, and was joined by a 1982 Audi Quattro A1 Group B rally car that won the 1983 championship and sold for nearly as much as its road-going counterpart at GBP253,480 ($377k). Those weren't even the highest-grossing lots at the auction though. The headline price was achieved by a 1959 Frazer Nash Le Mans Coupe that sold for a nice round GBP470,000 ($700k). Other highlights included a 1962 Aston Martin DB4s that went for the equivalent of $382k and a '66 Aston DB6 Vantage that brought in $288k. This was just the first of three auctions that Bonhams will hold at Goodwood this year, with the Festival of Speed scheduled for June 26 and the Revival for September 12. 1980S MOTORING LEGENDS LEAD THE WAY at Bonhams Goodwood Members' Meeting sale 21 Mar 2015, Goodwood 73rd Members' Meeting The ex-Kitty Maurice 1959 Frazer Nash Le Mans Coupe was the top lot of the day, selling for GBP470,000. 1980s models achieved excellent prices, with the 1985 Audi Quattro Sport SWB Coupe setting a new world auction record for the model at GBP287,100, and the ex-works, Hannu Mikkola/Arne Hertz 1982 Audi Quattro A1 Group B Rally Car selling for GBP253,480. The first of three Bonhams auctions scheduled at Goodwood for 2015, the Sale saw three-quarters of motor cars finding new homes. Restoration projects also proved popular, with a 1962 Aston Martin DB4 Series IV Sports Saloon achieving GBP256,860, and a 1963 Porsche 356B Super 90 Coupe doubling estimate at GBP32,200. Bonhams inaugural Sale at the 73rd Goodwood Members' Meeting showed a strong trend for iconic 1980s sports cars, achieving a new world auction record for an Audi Quattro as the hammer fell at GBP287,100 for the 1985 Sport SWB Coupe model.

TRANSLOGIC 147: CES 2014 Autonomous Vehicles

We head back to CES in Las Vegas to check on the progress of autonomous vehicles in 2014. We go hands-free on the highway with Audi, narrowly avoid a collision with Ford and hear all about BMW's drifting driverless car. But first we take a ride on Induct's self-driving Navia shuttle.
