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.

Audi R8 Spyder looks like heaven at the Green Hell

After Audi took the wraps off the new R8 coupe at the 2015 Geneva Motor Show, we knew it would only be a matter of time before the convertible version arrived. Now, we've spotted the droptop during testing on and around the venerable Nurburgring Nordschleife in Germany. The new Audi R8 Spyder is expected to closely mirror the fixed-roof supercar we've already seen. Only instead of a tin top, of course, it'll have a folding fabric roof mechanism. This goes against the recent retractable hardtop trend, and the featured is used by the Ferrari 488 Spider and McLaren 650S Spider. Some revised air vents appear to be part of the R8's convertible package, as well. Otherwise, we can anticipate the same specs as the R8 coupe. The latest model ditched the previous version's V8 engine in favor of 10-cylinder options: a 5.2-liter V10 with either 533 horsepower in "base" spec or 602 hp in the V10 Plus model. Both drive all four wheels through a seven-speed dual-cluch transmission. The jury's still out on whether Ingolstadt will slot a smaller engine option into the R8, particularly for markets where tax brackets are determined by engine displacement. But whatever the coupe gets, the convertible is likely to offer it as well. Related Video:

1956 DKW Audi electric van beautifully restored

These days, electric vehicles that make commercial deliveries aren't entirely rare. UPS has a small fleet in California, and at least 5,000 Renault Kangoo Z.E. models are in use by France's national postal service. But the history of this concept is much older. In fact, one of the companies represented by Audi's four rings had an example about 60 years ago. Audi Tradition just completed a full restoration of this blue 1956 DKW Elektro-Wagen to add to the company's collection of historic vehicles. It's quite a rare find because only two are still known to exist. Audi estimates that DKW built about 100 of these electric vans between 1955 and 1962, and they were primarily sold to energy companies, public utilities and battery makers. To create the EV model, DKW took its normal Schnellaster delivery van and replaced the model's two-stroke engine with an electric drivetrain. The vans weren't exactly speedy, though. The motor produced about 6.7 horsepower and lead-acid batteries offered 200 amp hours of power running at 80 volts. It gave the Elektro-Wagen a claimed range of about 50 miles and a 25 mile-per-hour top speed. Following the restoration, Audi took van to the island of Wangerooge in the North Sea to show it off. The location is perfect, too, because vehicles with internal combustion engines are banned on the island. If you can read German, feel free to find out more in the press release below. „DKW Elektro-Wagen" zu Audi heimgekehrt Einen von zwei verbliebenen DKW Elektro Schnellaster restauriert Klein-Bus einst auf der Nordseeinsel Wangerooge im Einsatz Audi Tradition prasentiert einen aussergewohnlichen Neuzugang in seiner historischen Sammlung: einen „DKW Elektro-Wagen" von 1956. Zwischen 1955 und 1962 produzierte die Auto Union GmbH in Ingolstadt DKW Schnellaster – etwa 100 davon als Elektro-Automobile, die das Unternehmen vor allem an Energieunternehmen, Stadtwerke oder Batteriehersteller verkaufte. Bei dem nun nach aufwandiger Restauration „heimgekehrten" Elektro-Schnellaster handelt es sich um ein besonderes Exponat: Der DKW fuhr auf der Nordseeinsel Wangerooge, wo Automobile mit Verbrennungsmotoren verboten sind. Normalerweise war der DKW Schnellaster mit einem Zweitaktmotor ausgestattet - der „Elektro-Wagen" hingegen mit einem funf Kilowatt (kw) leistenden Reihenschluss-Motor. Die seitlich in zwei Kasten gelagerten Bleibatterien hatten eine Nennspannung von 80 Volt und eine Kapazitat von 200 Amperestunden (AH).
