[robchalmers]

Audi have launched at the Geneva Show their newest car in the e-tron range. Based on the sound to be launched a1, Audi have used a 254cc (chamber cc) wankel rotary engine mounted in the boot to provide the charge to li-ion 'T cell' mounted under the rear seats. the control electronics and motors are up front were the regular A1's grubby bit would normally sit.
the car kicks out roughly 100hp, can break sixty in just over 10 seconds and weighs in at roughly 2600lbs

The range extender.
The A1 e-tron concept car has a Wankel engine as a range extender, but other compact concepts are also possible. The small single-rotor Wankel has a chamber volume of 254 cc and runs at a constant 5,000 rpm in its peak efficiency window. The electronics also consider navigation data such as the destination and route profile to automatically activate the range extender as needed. The driver can also turn the range extender on and off as necessary with the push of a button The fuel tank holds 12 liters (3.17 US gallons).

Is this a "classic" series hybrid with the engine running at it's BSFC peak?
