Volkswagen has unveiled the New Compact Coupé, a concept that delivers the seemingly contradictory mix of a petrol-engined, practical, performance-orientated coupé with extraordinary economy and sub-100 g/km CO2 emissions.

The New Compact Coupé, unveiled for the first time at the 2010 North American International Auto Show in Detroit, is capable of delivering economy and performance at the same time thanks to the adoption of a highly efficient 1.4-litre TSI engine developing 150 PS and 177 lbs ft of torque linked to a seven-speed DSG gearbox and an electric motor powered by a lithium ion battery. The electric motor, which generates 27 PS, can either work independently of the engine to make the New Compact Coupé a Full Hybrid or in tandem to provide a useful boost for overtaking.

Further optimising the efficiency of the vehicle is a 'coast down' system that takes the form of a clutch that disengages the TSI engine from the DSG transmission when not required to reduce friction. In addition, the kinetic energy that would otherwise be wasted is recovered through the electric motor which channels the power back to the lithium ion battery.

The result is the ability to accelerate from rest to 62 mph in 8.6 seconds before reaching a top speed of 141 mph mixed with a combined fuel figure of 67.2 mpg and carbon dioxide emissions of 98 g/km.

Styled by a team led by Klaus Bischoff, Head of Volkswagen Design, and overseen by Walter de Silva, Head of Design for the Volkswagen Group, the New Compact Coupé marks an evolution of the styling direction already seen on the Golf and Polo models.

The theme continues inside with four bucket seats finished in 'Berry White' leather and clean, simple surfaces. Despite being a coupé the concept features a large, practical boot measuring 380 litres.
