TheSI6(Short Inline 6) is a family ofstraight-six enginesdeveloped byVolvoand used by Land Rover and Volvo.

History

Volvo designed theSI6( "short inline 6" ) straight-6automobileengine for use in 2007 models. An evolution of the company's long-usedstraight-5Volvo Modular engine,which itself is an evolution of the Volvo B6304 straight six engine, the SI6 can be mountedtransverselyforfront wheel driveorall wheel driveapplications. Despite the added cylinder and displacement, the engine remains compact, and is in fact 1 mm (0.039 in) shorter than the previous straight-5. The engine was initially offered in two displacements — a 3.0 Lturbochargedversion and a 3.2 Lnaturally aspiratedversion. Both offeredvariable cam timing,though only the turbo version varies both the intake andexhaust valves.On top of the variable cam timing used on the intake cam of the naturally aspirated engine it also hadvariable valve liftby using Cam Profile Switching (CPS).

Production of the Volvo SI6 began at theFord Bridgend Engine PlantinWalesin May 2006. It was assumed that the engines would be used in European Ford and Jaguar products as well as Volvos.

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.
