How’s this for a hybrid? Volkswagen’s first-of-its-kind Twincharger engine, arriving this fall in the Europe-only Golf GT, marries a diminutive 1.4-liter, four-cylinder engine to both a supercharger and a turbocharger. The pint-size power plant gobbles oxygen, not gas, cranking out commendable performance and outstanding fuel economy.
Both ‘chargers work on the same principle: Force air into the engine to generate more power. At low rpms, the super-charger-driven by a belt connected to the engine’s crankshaft-blasts fresh air into the cylinders to enhance low-end torque. At high revs, the exhaust gas brings the turbocharger up to speed to bolster top-end performance.
VW won’t say if it plans to bring the Twincharger to North America, but if $3 for a gallon of gas becomes routine, the company just might find a market for a sporty 48mpg hatchback.
