Volkswagen has recently unveiled the Passat Hybrid at the 2012 Geneva Motor Show.
The model was conceived by Controlled Power Technologies (CPT) and the Advanced Lead-Acid Battery Consortium (ALABC), as a micro-mild demonstrator showcasing the capabilities of a new low-voltage hybrid-electric system. It is available in both diesel and gasoline configurations, achieving 42 miles per gallon (mpg US) with CO2 emissions under 130g/km. This new technology offers gasoline-fueled vehicles with lower cost than their equivalent diesel model.
Although the micro-mild technology adds some cost to the 1.4L model, it significantly raises fuel economy and also gives much better emissions standards. All these at a cost that is lower than the TDI model’s base price, which makes it much cheaper than a full hybrid system as well. The 1.4-liter base engine put out 120hp in the Passat and CPT raises that to 140hp, making the smaller engine more compatible with the larger 1.8L option. Using the SpeedStart stop-start system, which includes the advanced starter-generator, as well as intelligent torque and current control, efficiencies are further boosted.
