The engine is made of aluminum and features direct injection and a dry sump lubrication. The engine management system has been developed by Robert Bosch GmbH, the power is transmitted through a sequential, hydraulically actuated transmission with seven forward gears.

In addition to the recovery of braking energy on the front wheels electrical energy is obtained via a motor driven by the exhaust gas flow generator, which is then stored in water-cooled lithium - ion batteries that have been developed in collaboration with the company A123 Systems. When accelerating, the energy is delivered to the front wheels so that the rear-wheel drive vehicle has otherwise a temporary -wheel drive. Per round so up to 8 megajoules of energy may be supplied.
