To promote the drivability, the single turbocharger has been optimised to produce high torque from low revs. The high injection pressure results in particularly effective combustion. The injection system features another type of piezoelectric fuel injectors than in the D5, aiming to cut fuel consumption through extremely rapid and precise injection sequences. The engine has been optimised with low fuel consumption in sharp focus. The single-turbo 2.4D will be available in the Volvo S80 and Volvo V70 as well as in front-wheel-drive versions of the Volvo XC60 and Volvo XC70 from the spring of 2009. The single-turbo 2.4D - focus on fuel economy Together, the high-tech solutions contribute to the excellent fuel consumption (EU Combined) figures:ħ.0 litres/100 km (185 g/km) in the XC60 (preliminary).ħ.0 litres/100 km (185 g/km) in the XC70 (preliminary). At the same time, this technology and the efficient combustion create a pleasant sound bearing a closer resemblance to the elegant note of a six-cylinder petrol engine.

This provides precise distribution of the atomised fuel in the combustion chamber, resulting in efficient combustion and low emissions. The advanced fuel injection technology uses piezoelectric fuel injectors. This harnesses the two turbochargers' different properties optimally to deliver a combination of high performance and low fuel consumption that is bidding for the title of best in class. This twin-turbo technology in the D5 has also made it possible to introduce higher levels of exhaust gas recirculation (EGR) across a wider rev range than before. The result is alert response and rapid acceleration at all speeds, with very smooth power delivery between the turbo ranges. The performance and driveability requirements in the high-performance D5-engine have been solved with twin turbochargers of different sizes that operate in sequence to provide added power within a broader rev range. The high-performance D5-engine has already been introduced in the Volvo S80 and it will be available in the Volvo V70, Volvo XC60 and Volvo XC70 from the spring of 2009. 'This is yet another step in our determination to reduce the combustion engine's environmental impact, at the same time as we give customers truly quiet and sophisticated engines with excellent performance,' says Derek Crabb, Vice President, Powertrain Engineering at Volvo Cars.
