cam and helps to minimise emissions, especially when the engine is cold, and maximise
torque at low engine speeds.
Boasting a capacity of 2521cc, the 2.5T develops 210bhp and 320Nm of torque from as low
as 1,500rpm up to 4,500rpm, and provides impressive mid-range flexibility.
Against the stopwatch, the manual Volvo XC70 2.5T achieves 0-62mph in 8.1 seconds and a
maximum speed of 130mph. It is capable of 27.7mpg on the official Combined cycle with
emissions of 244 g/km. The figures for the Geartronic (auto) version are 8.5sec, 130mph,
25.4mpg and 266 g/km, respectively.
D5
In the UK, the majority (at least 86 per cent in 2004) of Volvo XC70 customers choose the
performance, flexibility and range of a diesel engine. And from the 2006 model year, Volvo
now offers a new, substantially updated version of Volvo's acclaimed and refined 2.4-litre,
five-cylinder turbodiesel: the D5.
The new D5 engine offers a six-speed manual gearbox or the option of a new six-speed
Geartronic (from October 2005).
These enhancements have been achieved as a result of customer feedback and achieved by
the following technological developments and extensive changes to performance
characteristics of the D5 diesel engine - see following details:
• New electronic glow plug system for faster starting.
• More advanced injection process with 7 spray holes (instead of 5) in each injector for
complete fuel atomisation and more efficient combustion and enhanced performance.
• New, larger and more efficient turbocharger with electronic control for faster/more precise
control of charge pressure; plus larger compressor wheel, new cambered vanes for
improved response at all speeds, and reduced turbo lag.
• Turbo centre housing now water cooled to provide continued cooling after engine stops.
• Improved flow of air/exhaust gases for optimal flow and reduced drop of pressure.
• More powerful engine management system with more sensors to improve regulation.
• EGR (Exhaust Gas Recirculation) system modified for improved flow/regulation.
• New, more effective cooling system for EGR.
• New, faster, electronically controlled throttle moves EGR gases/ regulates temp better.
• Air swirl in combustion chamber is now infinitely variable for more efficient combustion.
• Increased volume for combustion chambers, and consequently a lower compression ratio.
