An entirely new powertrain featuring a V8 engine, 6-speed automatic transmission and the latest-generation AWD system further broadens the customer base for the Volvo XC90. The new V8 engine marks a new turning-point in Volvo Cars' history. It is the first V8 the company has produced since it was founded in 1927, and the Volvo XC90 is the first model to be powered by the new engine.

In order to maintain overall compactness, all the ancillary units such as the alternator are fitted directly onto the engine itself without any space-stealing brackets. The starter motor is fitted above the transmission for the same reason. What is more, the exhaust camshafts are driven by secondary chains running off the inlet camshafts, saving additional space. The left-hand cylinder bank is offset half a cylinder ahead of the right bank, contradicting normal practice in the automotive world - so the engine can slot neatly into the structural beam network of the XC90 and thus enhance collision safety.

The Volvo XC90 V8 produces 315 horsepower and its torque - the most important characteristic of a V8 engine - is a massive 440 Nm at 3900 r/min. And at the sort of revs at which most driving takes place, around 2000 r/min, no less than 370 Nm of torque is at the driver's disposal. To increase the low end torque, the Volvo V8 has a valve in the inlet manifold that is closed below 3200 rpm. In this mode the air flow between the two cylinder banks is cut off, which creates a broader and more even torque curve.

The power from Volvo's V8 engine passes through an entirely new 6-speed automatic transmission dimensioned to handle the high torque. This unit too is of particularly compact dimensions so as not to interfere with the car's overall structure. Sixth gear is a pure overdrive ratio to ensure quiet cruising and low fuel consumption. The third ingredient in the new Volvo Cars V8 powertrain is the electronic AWD four-wheel drive system, which now features Instant Traction. This new technology - which Volvo Cars is the first automaker in the world to introduce -improves the scope for quick getaways and provides enhanced traction on slippery surfaces. It has been developed by the Swedish company Haldex.
