The SI6 (Short Inline 6) is a family of straight-six engines developed by Volvo and used by Land Rover and Volvo.

History

Volvo designed the SI6^[3] ("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 1mm 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).

Production of the Volvo SI6 began at the Ford Bridgend Engine Plant in Wales in May 2006. It was assumed that the engines would be used in European Ford and Jaguar products as well as Volvos.^{[4] [5]}

Nomenclature

The engine codes consist of a series of letters and digits:

• 1st: Fuel type (B) B = Bensin (Petrol)
• 2nd: Number of cylinders (6)
• 3rd & 4th: Approximate displacement in deciliters, may be rounded up or down. (29 ~= 3.0 L)
• 5th: Valves per cylinder (4)
• 6th: Induction method (S/T) S = suction (naturally aspirated), T = turbocharged
• 7th: Engine variant (2/4/5)

Engine codes are not necessarily unique to a specific engine as power levels can vary depending on market, manufacturer and model.
