Audi e-tron quattro all electric SUV w/ 300+ mile range, concept car

The Audi e-tron quattro is an all-electric SUV that’s expected to have a 310 mile range.  The concept vehicle is to be shown at the 2015 Frankfurt International Motor Show, and Audi promises an “outlook on the brand’s first large-series electric car”.

It’s been designed from the ground up as an electric car, rather than having the electric drive train retrofitted into an existing gasoline car.  It’s designed with great aerodynamics, comprised of movable aerodynamic elements at the front, on the sides and at the rear to improve the air flow around the car.  The aerodynamically optimized underbody is completely closed.  It results in a cd value of 0.25.

It’s based on Audi’s second-generation modular longitudinal platform, providing considerable scope for the drive system and package. The e-tron quattro’s length is between that of the Audi Q5 and the Q7.  The spacious interior offers room for four people.

It’s driven with three electric motors – one on the front axle and two on the rear axle – drive the Audi e-tron quattro concept.

The battery pack is, like many electric cars, located between the axles below the passenger compartment.  That helps lower the center of gravity for improved driving dynamics and driving safety.

The battery pack is the result of a collaboration between LG Chem and Samsung SDI.   The two companies plan to invest in the cell technology in Europe and will supply Audi from European battery factories.

To supply the 310 mile range, the battery pack probably must be 100 kiloWatt-hours.
