Finally, we have the full, complete details on the Volkswagen Golf TDI Hybrid concept. Before we get into the nitty-gritty, lets get one thing out of the way. Volkswagen confirms that a version of this very car is likely to see production (in Europe, at least). Now, on to the details. The Golf TDI hybrid pairs a 74 hp/132 lb-ft 1.2L 3-cylinder diesel (not the 1.4L used in the Polo BlueMotion, as had been speculated) with a 26.6 hp/103 lb-ft electric motor. At low speeds, the car will run in EV-only mode, with the TDI joining in if/when necessary. The tandem should be good for for 69 US mpg and 89 g/km of CO2 emissions in the EU combined cycle. The electric motor replaces the starter motor and alternator, and it will also charge the car's 220v NiMH battery via regenerative braking. When stopped, the diesel cuts out entirely. This is behavior that hybrid drivers are accustomed to. Where this Golf concept veers from the norm somewhat is in its use of a 7-speed DSG instead of a CVT. According to VW, using the dual-clutch transmission helps maximize fuel economy. What's left unsaid, but is known to anyone who has driven a DSG-equipped VW or Audi, is that it should also make it much more engaging to drive, given that the operator can manually shift if he or she wants to.
Visually, the Golf TDI Hybrid is lowered, has smaller intakes, sports a unique grille design, and wears aerodynamic wheels with low-rolling-resistance tires -- all lessons VW has learned with its various Euro-market BlueMotion offerings. The front splitter is the same one used on the GTI Edition 30, and occupants will find a uniquely-trimmed interior waiting for them. Overall, this is a very attractive package that pairs a popular, practical body style with a compelling drivetrain that should not struggle in any normal driving situation. 100+ horses and 235 lb-ft of combined power ensure that the Golf TDI Hybrid can merge and pass with ease, and its hybrid operation should make it excel in local/urban runabout duty. They may be late to the party, but VW looks to have brought something good for the guests to try.
