# NOMECLATURE WHITEBLOCK ENGINES Volvo **Whiteblock engines** were produced from **1990 to 2016**, with some variants continuing slightly beyond in limited use. ### 🔧 Key Details: - **"Whiteblock"** refers to a family of modular Volvo engines with an aluminum (hence the term "white") engine block and head. - Used across **inline-5**, **inline-6**, and **inline-4** configurations. - Known for their **modularity, durability, and turbocharged performance**. --- ### 🗓️ **Production Years by Engine Type:**

Engine Type	Years Produced	Notes
Inline-5	1991–2016	Found in 850, S70, V70, C70, S60, XC90, etc.
Inline-6	1990–1998 (RWD)	960/S90/V90 (B6304, B6294)
	2006–2016 (FWD/AWD)	Used in S80, XC60, XC90 (3.0T, 3.2)
Inline-4	1996–2004	Less common; seen in S40/V40 and some Euro markets

The engine codes consist of a series of letters and digits. The actual, broadly used engine code is 7 or 8 characters long. Hybrid models can have a second engine code that is 7 characters long, mild hybrids engine codes are 6 characters long. Different, more general engine codes are used for some certification and approval documents and are 6 to 8 characters long. An additional 2 characters are used to identify each specific engine variant with an *MP* or *HP* suffix to differentiate performance. ### The engine codes consist of a series of letters and digits: - 1st: Fuel type (B/D/GB) **B** = Bensin (Petrol), **D** = Diesel, **GB**= Gas & Bensin - 2nd: Number of cylinders (4/5/6) - 3rd & 4th: Approximate displacement in deciliters, may be rounded up or down. (23 ~= 2.3 L) - 5th: Valves per cylinder (2/4) - 6th: Induction method (S/T/F/G/GS/FS/FT/SG) - 7th: Engine generation or engine variant (2/3/4/5/6/7/8/9/10/11)

**S** = standard (naturally aspirated),

**T** = turbocharged,

**F** = fuel injection with catalytic converter,

**G**= leaded fuel compatible,

**GS**= leaded fuel compatible, naturally aspirated,

**FS** = fuel injected standard (naturally aspirated) with catalytic converter

**FT** = fuel injected, turbocharged with catalytic converter,

**SG**= standard (naturally aspirated) compatible with alternative fuels ([LPG](https://en.wikipedia.org/wiki/Liquefied_petroleum_gas) / [CNG](https://en.wikipedia.org/wiki/Compressed_natural_gas))

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