Volkswagen's Hybrid Compact Coupe In Detroit

DETROIT, MICHIGAN - Volkswagen premiered their advanced New Compact Hybrid Coupe at the 2010 North American International Auto Show in Detroit Michigan this week and it showed that the company is very focused on delivering higher levels of efficiency in their product line-up for the future. Officially called the VW New Compact Coupé, the car has a high efficiency 1.4-litre TSI gasoline engine that develops 150 hp and 177 ft-lbs of torque integrated with a 27 hp hybrid electric motor.

The VW New Compact Coupé can run entirely on the electric motor when there is charged energy available, or integrate with the power from the gasoline (petrol) engine to improve on-demand acceleration. Following the trend to optimize gear transmission efficiency, the Volkswagen New Compact Coupé has a seven-speed DSG gearbox that includes a revolutionary clutch disengage 'coast down' system to reduce gear and powertrain drag friction and improve fuel efficiency. The New Compact Coupé captures deceleration kinetic energy by reversing polarity of the electric motor to charge the battery.

Where VW has excelled is in the achievement of both power and fuel efficiency in the New Compact Coupe, and much can be attributed to both the lithium-ion battery storage and the coast down disengage system for this result. This new VW concept hybrid coupé achieves a combined fuel efficiency of 56 U.S. MPG,  67.2 IMP MPG, 4.2 L/100 km and it accelerates from zero to 62 mph (100 km/h) in 8.6 seconds with a very low CO2 output of just 98 g/km.

Exterior design on the New VW Compact Hybrid Coupe incorporates bi-xenon headlights and 19-inch 'Lugano' alloy wheels, while the interior has four bucket type seats in 'Berry White' leather. Volkswagen has not yet announced whether the New Compact Coupe will see production status, but the efficiency improvements seen with the coast-down system are bound to make their way into many future VW models.
