The show car is said to accelerate from 0 to 62mph in 5.1 seconds. Its top speed is limited to 155mph. The prologue Avant’s average consumption is rated at up to 176mpg Combined according to the NEDC standard for plug-in hybrid vehicles – corresponding to 43 grams of carbon emissions per kilometre. The lithium-ion battery pack in the rear stores 14.1kWh of energy and gives the car a claimed range of 55km in pure electric drive mode.
With its AWC (Audi wireless charging) technology which Audi is developing for series production, the battery can also be charged inductively. AWC draws energy from a floor plate which is connected to the power grid and which can be embedded on or into the asphalt. The plate integrates a primary coil and an inverter (AC/AC converter). When active, this coil induces a magnetic field of alternating current.
