Ford's Volvo Cars subsidiary designed the SI6 ("short inline 6") straight-6 automobile engine for use in 2007 models. An evolution of the company's long-used straight-5, which itself is an evolution of the Volvo B6304 straight six engine, the SI6 can be mounted transversely for front wheel drive applications or longitudinally for rear wheel drive. Despite the added cylinder and displacement, the engine remains compact, and is in fact 1 mm shorter than the previous straight-5. The engine will be offered in two displacements initially — a 3.0 L turbocharged version and a 3.2 L naturally aspirated version. Both offer variable cam timing, though only the turbo version varies both the intake and exhaust valves. On top of the variable cam timing used on the intake cam of the naturally aspirated it also has variable valve lift by using Cam Profile Switching (CPS).
