VW Golf GT 1.4L (Turbo charged and supercharged at the same time)
1.4L engine is the world’s first application of a twincharged FSI powerplant and it also holds the title of delivering the highest output per liter for a production four-cylinder engine. Peak output stands at 168hp (125kW) with maximum torque of 240Nm (177lb-ft) plateauing from a lowly 1,750rpm to 4,500rpm. Remember, this is a 1.4L petrol powered engine but with the low torque characteristics and fuel efficiency of a diesel.
The key to its prowess is the combination of a mechanically driven supercharger for the lower revs with an exhaust driven turbocharger kicking in as revs start to rise. To boost output further, engineers also added a revised version of VW’s FSI direct-injection technology. The end result is the power characteristics of a 2.3L engine but with 20% lower fuel consumption.
