If there is more trendy than in the automotive world that be the range extended electric They seem to combine all the of an electric car (quiet, clean, acceleration, ease of use etc) the risk of stuck in the middle of with empty batteries or some hours from to charge when in hurry. has already show 2 ‘e-tron’ but the 3rd one, this A1 e-tron is the realistic and also the most It is basically an electric vehicle, by an array of Li-ion batteries but is a small internal combustion in the back and it is a one-rotor Wankel

The image above shows the of the electric propulsion. In the front is the electric motor that the front wheels, the electronics and units and also all the auxiliary of the car (A/C, brake pumps The batteries are below the rear and in the back there is the small ic module.

Power reaches the front only via the electric motor, the ic needed is used only to the batteries.


In a regular hybrid the motor and the ic engine work in a way to compliment each other. in a range extended vehicle the is mostly electric, the ic engine is as an emergency feature in order to power instantly when the charge is low.

The most famous and first extender wannabe, the Chevrolet uses its 1.4lt turbo as an auxiliary unit but the volume and the of it is unproportional to its role. In the A1 e-tron the engine with its small tank fills just the of the luggage compartment (and is a small car). It has one rotor and 254ccm of displacement but can provide a 15kW of power.
