Volkswagen show Golf TDI hybrid concept at Geneva

Volkswagen has chosen the Geneva motor show to unveil a Golf based
hybrid concept car. The TDI hybrid concept combines a 1.2 litre diesel
engine producing 74 bhp with VW’s latest 7 speed DSG gearbox and an
electric motor to produce a parallel hybrid system.

VW’s new 7 speed DSG is an evolution of their highly acclaimed 6 speed
DSG gearbox that has been in production since 2003. The gearbox has
been designed for lower powered engines producing less than 184 lbs ft
of torque which allows a dry clutch arrangement to be used rather than
the wet clutches in the original unit. This has allowed the engineers
to reduce the size of the gearbox, its weight and the frictional forces
which makes it more efficient than the wet clutch arrangement. The
added ratio further enhances efficiency making the gearbox more
efficient than a 6 speed manual.

VW claim that the concept is capable of achieving 83 mpg on the
combined cycle which equates to just 89 g/km of CO2. The excellent fuel
consumption is aided by the hybrid system which allows the golf to be
driven in electric mode at urban speeds.

At the moment the Golf Hybrid is a concept model but it achieves very
similar fuel consumption figures to Peugeot/Citroen’s 308/C4 hybrid
concepts which are believed to be largely production ready being tipped
to enter production around 2010.
