What type of engine competes with the 6.6-liter Duramax that is produced by DMAX?
Ford Power Stroke engine Power Stroke is a line of diesel engines found in Ford diesel trucks, Ford Excursion SUVs, Ford Econoline vans, Ford LCF commercial vehicles and the Brazilian Ford Ranger. The V8 engines were produced by Navistar International Corp. until 2010 when Ford decided to build their diesel engine completely in-house. The Power Stroke engines compete primarily in the United States full-size pickup truck market with the Duramax V8 from General Motors/Isuzu and the B Series straight-six from Cummins.
Volvo SI6 engine Volvo 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 Volvo Modular engine, which itself is an evolution of the Volvo B6304 straight six engine, the SI6 can be mounted transversely for front wheel drive or all wheel drive applications. Despite the added cylinder and displacement, the engine remains compact, and is in fact 1 mm shorter than the previous straight-5. The engine was initially offered in two displacements — a 3.0 L turbocharged version and a 3.2 L naturally aspirated version. Both offered 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 engine it also had variable valve lift by using Cam Profile Switching (CPS).
