After teasing us with a few goodies yesterday, Audi has just released technical details on its new A1 e-tron concept that debuts later today at the Geneva Motor Show. As we already knew, the A1 uses an extended range electric architecture like the Chevrolet Volt, but with a compact and power-dense Wankel rotary engine/generator to keep the battery alive after power from the grid is depleted. The diagrams released by Audi show that the Wankel is mounted in the car’s rear behind the T-shaped battery pack that sits mostly under the rear seat.

The lithium ion battery pack has a capacity of 12 kilowatt-hours, which is claimed to provide about 30 miles of range on a charge. Unlike the 1,000+ pound pack in the original e-tron concept, this unit weighs in at just 330 pounds. The electric motor provides a standard output of 45 kW or 61 horsepower, though peak power of 75 kW or 102 hp is available in short bursts and keeps the car’s 0-62 mile-per-hour time around 10 seconds. The motor and all of the power electronics reside in the car’s front where the internal combustion powerplant of a conventional A1 would normally be found.

The Wankel weighs in at just 154 lbs and displaces just 254 cc of volume in its single rotor. The whole unit is small enough to sit below the cargo floor of the A1. Running at a constant 5,000 rpm, the rotary motor can extend the A1 e-tron’s range to 130 miles. Why not longer? The fuel tank holds only 3.17 gallons. With the Wankel running, Audi says the A1 e-tron will return about 124 miles per gallon U.S.

Of historical note, the first ever production car with a Wankel rotary engine was introduced by NSU back in 1964. NSU later merged with Auto Union, which also included Audi, the sole surviving brand of the group.

At last month’s Frankfurt Motor Show, Audi board member Michael Dick confirmed that a production version of the electric eTron sports car concept would be produced by late 2012. Following the show, Audi NA president Johan de Nysschen confirmed that announcement and now AutoExpress has produced a rendering of a production model. However, there appears to be some details lost in the translation. The eTron is based on the aluminum space frame of the R8 while AE says the R4 will be a smaller roadster with a chassis shared with the next generation Porsche Boxster/Cayman.

An Audi R4 has been speculated for some time, with the rumors flaring up after VW showed off the concept BlueSport in Detroit this year. It’s not clear if Audi will move ahead with the larger R8-based EV sportster or a smaller machine, or perhaps both. If they do, something like this rendering would be welcome, combining elements of the BlueSport, the eTron and even the top and flying buttresses of a Lotus Elise.
