Volvo has unveiled the new 2.0-liter GTDi (Gasoline TurbochargedDirect Injection) four-cylinder engine for the S80, V70, and XC60.
Featuring a turbocharger, direct injection, and twin variablecamshafts, the engine offers "a unique combination of low fuelconsumption, low emissions and high performance across a wide revrange." More importantly, the engine is outfitted with the world'sfirst exhaust manifold and integrated turbine system made of sheetsteel. While this sound pretty boring, Volvo says "The sheet (steel) islighter and more compact and, above all, this system generates lessheat owing to its extra insulating layer. This allows high gas flowtemperature and thus more efficient combustion. "
Jointly developed with Borg-Warner and Benteler Automotive (a steelcomponent manufacturer), the engine produces 203 hp and 300 Nm (320 Nmwith overboost). While Volvo declined to release full performance data,they stated a GTDi-equipped S80 would consume 8.3 liters of petrol per100 kilometers (28 mpg).
According to Magnus Jonsson, head of Product Development at VolvoCars, "We've succeeded in making a four-cylinder engine that is aspowerful as a 2.5-litre five-cylinder unit, and it's also much moreenergy-efficient. This is a very welcome both for those customers whowant high performance as well as supreme driveability and for theenvironment that benefits from the improved fuel efficiency. One of themost important reasons behind the results is our new, patented turbosystem that has been tailor-made for smaller energy-efficient engines."
The GTDi engine will be initially launched in South-East Asia, theNetherlands, China and Japan. It will be available with a six-speedmanual or a six-speed double-clutch automatic transmission.
