Volvo began offering a 4.4 L V8 engine in its large P2 platform automobiles in 2005. It was initially offered only for the Volvo XC90 but later found its way in the second generation Volvo S80. and mated to a six speed Aisin Seiki transmission of Japan also with a Swedish Haldex all wheel drive system AWD. The 4.4 L V8 Volvo engine was built by Yamaha in Japan under Volvo design and specifications.
The engine was unique in Ford's† wide range of V8 engines in that it is designed for transverse use and has a V6-like 60° bank angle. Officials of all three companies involved insist that the Volvo V8 is not related to the SHO engine; the die-cast open-deck aluminum Volvo block is clearly different from the sand-cast closed-deck aluminum SHO engine block although the two engines share many common dimensions including bore centers, stroke, bearing journal diameters, and deck height.
As revealed in BBC's Top Gear show (Series 14 Episode 5) this basic engine is also used in the Noble M600, albeit longitudinally mounted, developing some 650 horsepower with the addition of 2 turbochargers. The Noble unit is custom built by a 3rd party firm expressly for Noble Cars UK.
Volvo discontinued the engine subsequent to its change in ownership and management in August, 2010. The new management intends to offer a single engine across all Volvo models, ultimately a four cylinder. <Motor Trend, August, 2010.>
† At that point in time Volvo was owned by Ford.
As a Volvo V8, this new engine uses the similar Volvo engine naming system. The engine is called the Volvo B8444S. B being for bensin (gasoline), 8 for the number of cylinders, 4.4 for the total displacement of the engine, the last 4 for the number of valves per cylinder and S for suction, meaning it's naturally aspirated. This engine also uses original Volvo parts.
The engine is a 4.4 L aluminum DOHC V8 which produces 315 PS (232 kW; 311 hp) and 440 N⋅m (325 lb⋅ft). It has a 60 degree cylinder bank. The engine block and heads are cast from aluminium reducing its weight to a comparatively light 418 lb (190 kg).
The engine block was also used for the Yamaha F300V8 and the F350V8 outboards. The displacement was 5.3 litres, respectively.
