More Info About GTDI TECHNOLOGY


actuallyGTDI TECHNOLOGY mostly introdused in volvo , the Volvo has unveiled the new 2.0-liter GTDi (Gasoline Turbocharged Direct Injection) four-cylinder engine for the S80, V70, and XC60 vehicles.

Featuring a turbocharger, direct injection, and twin variable camshafts, the engine offers "a unique combination of low fuel consumption, low emissions and high performance across a wide rev range." More importantly, the engine is outfitted with the world's first exhaust manifold and integrated turbine system made of sheet steel. While this sound pretty boring, Volvo says "The sheet (steel) is lighter and more compact and, above all, this system generates less heat owing to its extra insulating layer. This allows high gas flow temperature and thus more efficient combustion. "

Jointly developed with Borg-Warner and Benteler Automotive (a steel component manufacturer), the engine produces 203 hp and 300 Nm (320 Nm with overboost). While Volvo declined to release full performance data, they stated a GTDi-equipped S80 would consume 8.3 liters of petrol per 100 kilometers (28 mpg).

According to Magnus Jonsson, head of Product Development at Volvo Cars, "We've succeeded in making a four-cylinder engine that is as powerful as a 2.5-litre five-cylinder unit, and it's also much more energy-efficient. This is a very welcome both for those customers who want high performance as well as supreme driveability and for the environment that benefits from the improved fuel efficiency. One of the most important reasons behind the results is our new, patented turbo system that has been tailor-made for smaller energy-efficient engines."
