Platform codes[edit]

GM used a lettered system of automobile platform codes for three decades. These letters were used as the fourth position of the VIN. Though today's GM platforms use Greek characters, they are still encoded with Latin characters in the fourth position. Position five encodes the specific model and trim level of the vehicle.

American engine codes[edit]

GM encodes the engine type in character 8 of the VIN. The following table outlines the various engines encoded there:

Engine codes for passenger cars[edit]

2010 Chevy Malibu engine code B, 2.4lMistake on the engine code M, this M code comes out on the 1995 - 1999 Chevrolet Monte Carlo and the engine is an RPO L82 3.1 SFI engine. This engine made it's first appearance on the A-Body sisters Buick Century and Oldsmobile's Cutlass Ciera 'S', the 1994 L-Body Chevrolet Beretta/Corsica, and it's N-Body siblings, which include the Buick Skylark, Oldsmobile Achieva, and Pontiac Grand Am, but Oldsmobile also had offerings of this engine offering in the 'Late' 1993 W-Body Cutlass for the engine to also incorporate into the 1994 model year W-Bodies, which included the Buick Regal and Pontiac Grand Prix, with the aforementioned Monte Carlo and it's sedan equivalent, the revised Lumina to follow suit the next model year, 1995. It continued it's second iteration, the LG8 3.1 in 2000 (VIN code 'J'), which finally ceased production in the 2005 model year W-Body version of the Century.

VIN code T also designates a 3.1 V6, the base engine in the 1990-92 Camaro/Firebird platform, and VIN code 8 is much better known as the L98 5.7 V8 TPI, standard in the 1985-91 Corvette and optional in the 1987-92 Camaro/Firebird platform .

Missing Entry: 1985-1988 Pontiac Fieros have a 9 engine code for the 2.8L L44 V6.

Missing Entry: The 2009 Corvette and 2011 Camaro SS use a W engine code for the 6.2L LS3 V8.

Missing Entry: Vin Code V for 2.4 L LE9 2.4L MFI I4

Warning: Issues with the decoding are related to year/model combinations. Such as the 4.1 V6 is not included in the list, however it was used on El Dorada and some Cadillac models. Each Year has different break down for each code, a complete list would be a subject of its own. Along with Plants and some model break downs over years.

Missing Entry: 1991 Limo with engine code 7, is not listed. According to one source the limo engine is a 5.7L.
