recently built twenty prototype diesel plug-in hybrid Golf
prototypes for a field test of the technology. AutoExpress magazine in the UK recently had an opportunity to try out the so-called Twin-Drive Golf. The Twin-Drive combines a 1.5L diesel
with electric drive and lithium ion batteries with plug-in capability. A pair of wheel motors turn the back wheels providing all wheel drive capability while a third motor and generator are combined with the diesel engine at the front axle. With a very light foot on the go pedal, the Twin-Drive can go to 31 mph on electricity alone. It can reportedly go 30 miles on a charge of its Sanyo battery pack. The plug-in hybrid
hardware adds 550 lb of mass to the Golf but it yields up to 94.1 mpg (U.S.), according to VW
. AutoExpress says the even distribution of the new mass keeps things balanced but the car does feel heavier than a standard Golf. It's unlikely we'll see a production VW with this configuration anytime soon though. The cost would simply be prohibitive.
