    Audi recently released specs and pictures of an Audi A5 based etron. Audi is still calling their electric driven model lineup e-tron despite it being French for poo-poo. In any case, I'm sure the cars aren't poo-poo. In fact, the A5 is quite a fine car despite being on the heavy side.

    As seen in the below diagram, the A5 e-tron prototype does have a gasoline internal combustion engine but it's not powering anything other than the generator. The car's drive power is from the electric motors and at no time does the gasoline engine directly drive the car. This is unlike the Volt, whose gas engine does provide some drive power at highway speeds because they say it's more efficient. I'm 100% this is not the case with this car because as you can see, there is no connection between the engine and drive motors. The Volt uses a planetary transmission to connect the engine, motor, and drive components.

    As a follow up to this post, YES, the battery pack is lithium ion and not nickel metal hydride. Li-ion is more expensive but is lighter and has more energy density.

    It also has plug in ability. According to Audi, this prototype's 9.4 kWh battery can be fully charged in 2 hours with a 230V household outlet.
