English company shows V10 hybrid sports car

Three modes alter how the electric motor is used. Sport mode uses all available motor assistance, but will use up the battery power so it cannot be engaged all the time. Normal mode adds battery charging on deceleration (regenerative braking) and rations the motor assistance.

Economy mode maximises the deceleration charge. Pressing the sport button also opens valves in the intake and exhaust systems for a sportier sound – 'like a Formula One car at half speed,' says Tim Bishop.
