According to a report out of Italy, Audi boss Rupert Stadler has said that the Audi A1 e-tron concept will not see production. Apparently the house of Audi believes that the conventional A1 will be sufficiently frugal and kind enough on the environment with its stop/start and brake energy recovery system. Additionally, there seems to be some issues with the A1's platform and its ability to house all the necessary EV components. If true, 'tis a shame – that cargo-floor-mounted Wankel engine paired with lithium-ion batteries was supposed to be good for 154 miles per gallon, and the A1 e-tron is a package we would have enjoyed by being so green we made grass jealous.
To bad it was kind of a cool concept---different than the volt as the little rotary was tucked away neatly in the back.
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.
