VW hearts biodiesel, hydrogen and clean TDI in SoCal
What's the engine in that Jetta? A TSI that gets high power output from a smaller displacement engine. It uses a supercharger to provide engine boost at lower rpms and an exhaust-driven turbocharger at mid-range rpms and higher. Already popular in Europe, the TSI is being considered for the U.S. market.
The Touran HyMotion hydrogen fuel cell vehicle uses a high-temperature fuel cell that VW says, "provides a more compact, lighter, and more durable fuel cell system."
