The Rimac Automobili Concept_One promises to be one of the highlights of the 2011 Frankfurt Motor Show.

The Concept_One is an electric hypercar claiming truly neck-snapping performance: 811kW of power, 3800Nm of torque, 0-100km/h in 2.8 seconds, and an electronically limited top speed of 305km/h.

The Croatian concept is powered by four independent electric motors, one driving each wheel. Each power unit incorporates a high-speed liquid-cooled permanent magnet electric motor, an inverter unit and a reduction gearbox.

Each wheel can accelerate or decelerate independently hundreds of times per second. Sophisticated ECUs control each of the power system, using the input of precise sensors placed all over the car.

Rimac says the architecture allows for a new approach to vehicle dynamics, which it calls All Wheel Torque Vectoring (AWTV).

With a low centre of gravity, extremely high torque available almost from zero rpm and the lack of shift interruptions, Rimac says the Concept_One will offer “a completely new driving experience”.

There’s also word that the car will weight around 1650kg and have a full electric driving range of 600km.

We’ll find out tomorrow if the Rimac Automobili Concept_One can really match the pre-show hype when it makes its debut at tomorrow’s Frankfurt Motor Show.
