Volkswagen will launch an innovative new sporty hybrid system in the sixth-generation Jetta that will go beyond what’s expected of current mainstream hybrids as it offers increased performance and economy.
Jetta technical project manager Michael Hinz said in an interview with Autocar, that it didn’t want to do what experienced hybrid makers like Toyota or Honda were doing.
He added that VW aimed for “something unique.” Hinz said that hybrid systems can be used to enhance power or raise efficiency. He indicated that to boost power, a turbocharged petrol engine is preferred. But for economy, he pointed to a diesel-electric system route.
Already confirmed for Europe in 2012, the Jetta’s petrol-electric hybrid system will use one of VW’s smaller-capacity TSI petrol engines.
This makes it likely that VW’s mainstream hybrid system will be used to boost the performance of its powerful turbo petrol range. Hinz clarified that the Jetta’s hybrid system will be different from the one on the Touareg, which was designed to improve efficiency.
Hinz doubts the efficiency of hybrids, saying that they really aren’t since more weight is added. He said that one could do a “power hybrid” but that they are “not going to do both.” At this year’s Detroit motor show, Volkswagen previewed its hybrid system on its New Compact Coupé concept.
