VW Introduces New TSI Engine and 7-Speed DSG Gearbox; More Power, Less Fuel
27 April 2007
VW introduced a new member of its turbocharged gasoline direct-injection TSI engine family at the Vienna Motor Symposium: a 1.4-liter, 90 kW (122 hp) version that develops up to 200 Nm (148 lb-ft) of torque. The company also introduced a new 7-speed double shift gearbox (DSG).
With a 7% increase in power compared to the normally aspirated 1.6-liter FSI engine, the new TSI delivers a 30% increase in peak torque, while reducing fuel consumption by about 6%.
VW based the new engine on the higher-power Twincharger units in the TSI family (earlier post), but does not use the supercharger in addition to the turbochargers as they do.
The new seven-speed DSG, which unlike the six-speed DSG uses a dry sump, also offers better efficiency.
VW will apply both technologies in the Golf for an estimated fuel consumption of 5.9 l/100km (40 mpg US).
