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