German automaker Volkswagen has experimented with several car models that use diesel and hybrid powertrains, two technologies that have taken a long time for American drivers to grow accustomed to. Now, however, Volkswagen is working on a new concept that will marry diesel and hybrid technologies together into one design, a plug-in hybrid called the Golf Twin Drive.
This technology, combining a 122-horsepower diesel engine and an 82-horsepower electric motor, will debut inside a typical Golf model design. Volkswagen also plans to work with electronics company Sanyo to develop lithium-ion batteries, which should give the Golf Twin Drive an all-electric range of about 31 miles (49.9 kilometers). Expect to see fleet models emerging sometime in 2010, with potential mass-production to follow.
