Volvo’s latest D5 turbodiesel engine will debut in the flagship S80 saloon
Volvo is introducing a new 2.4L diesel engine in the Volvo S80, with the only commonality between it and the outgoing mill being the D5 badge and five-cylinder configuration. The new engine is Euro 5 compliant and will be available for sale in Europe from the middle of the year.
With innovative engineering solutions such as sequential twin turbochargers, ceramic glow-plugs and piezoelectric fuel injectors, Volvo's engineers have succeeded in cutting fuel consumption to some of the lowest levels for a car of this size – 38mpg (6.2L/100km) and C02 emissions of roughly 164g/km. Despite its frugality, the engine is rated at a reasonable 205hp (152kW) and 310lb-ft (420Nm) of torque.
The D5 engine is made entirely out of aluminium, giving low weight and good heat dissipation properties. Transverse cooling gives uniform cooling of the cylinder head and engine block. This promotes a controlled temperature throughout the engine and contributes to improved reliability. The two turbochargers are of different sizes and together deliver high boost pressure, 26psi (1.8bar), across a broad rev range.
The new five-cylinder diesel is the first engine from Volvo's new project office for diesel engine development and took three years to complete. The carmaker is yet to reveal which other models the new oil-burner will be used in.
