VW has confirmed that the upcoming VW Jetta Hybrid will use a Twincharger engine.
First, we now know that the Jetta hybrid will use a full hybrid system, meaning it can operate solely on energy stored in the batteries. What we find more interesting, however, is that the Jetta hybrid’s gasoline motor will be VeeDub’s twincharger TSI mill. This will mark the engine’s U.S. debut.
So what’s this “twincharged” motor all about? Well, it’s a 1.4-liter four-cylinder that uses both a supercharger and a turbocharger, and it has been offered in Europe for a few years now in the VW Golf. The supercharger provides boost at low rpm and the turbo kicks in for the upper rev range. Combine the forced induction with direct injection, and the little engine provides nearly the same drivability as the 2.0-liter turbo, but is more efficient and therefore produces fewer emissions.
