The German automotive business, Volkswagen Group has, since the 1970s, developed a series of shared automobile platforms for their motor vehicles.[1][2]

Originally, these were identified using a simple alphanumeric system. The first letter prefix indicates the car classification or physical size (A, B, C or D - for 'traditional' cars); followed by a number to enumerate different generations of the same class. However, more recent platforms have formally departed from this convention, although the older alphanumeric codes continue to be used informally.

These platforms may be used by one or more marques of the Group.

Platform codesEdit

Original systemEdit

Volkswagen Group alphanumeric platforms
platform nameused fornotable examplescomments
A00 city carsVolkswagen Lupo, SEAT ArosaThis platform never developed any subsequent evolutions or generations.
A0 series supermini carsAudi 50, Volkswagen Polo, SEAT Ibiza, SEAT Córdoba, Škoda FabiaAs of 2010, now in its fifth generation.
A series[2] small family cars
/ compact cars
Audi A3, Audi TT, VW Golf, VW Jetta, VW Eos, VW Tiguan, VW Touran, VW Scirocco, SEAT León, SEAT Toledo, SEAT Altea, Škoda OctaviaThe most prolific platform, currently in its sixth generation.
B series[2] mid-size carsAudi 80, Audi 90, Audi A4, Volkswagen Passat, SEAT Exeo, Škoda SuperbAnother prolific platform, now informally in its eighth generation.
C series[2] extended mid-size executive carsAudi 100/200, Audi A6, Audi A6 allroad quattroSix generations to date.
D series full-size luxury carsAudi V8, Audi A8, Bentley Continental GT, Volkswagen Phaetonfive variants from four generations. Confusingly, the D series includes models using both conventional steel monocoque construction, or the very different aluminium Audi Space Frame construction.
T series vansVolkswagen Transporter rangethe early generations were retrospectively named, the T1 is the oldest "platform", based on the original Type 1 Volkswagen Beetle.

Note that some designations in common use are ambiguous; ie. in some cases the same platform designation is used for different models that do not share a common platform. An example would be the B6 designation - this is used to identify the 2001-2005 Audi A4 (and the related Audi S4), which uses a longitudinal engine and transmission placement with a pressed steel front subframe; however it is also used to identify the sixth-generation Volkswagen Passat, but this uses a transverse engine and transmission placement with a very different cast aluminium alloy front subframe.

Joint-venture platformsEdit

Platforms developed by Volkswagen Group as joint ventures with other manufacturers have designations which do not conform to the above scheme. These include:

LT/T1N series light commercial vehiclesVolkswagen LT range, Mercedes-Benz SprinterSecond and third generations are a joint-venture with Daimler AG.

Current systemEdit

More recently, Volkswagen Group have introduced a new alphanumeric nomenclature for car platforms. The platform code is composed as follows:

  • A letter, P, indicating a passenger car platform
  • A letter indicating the configuration of the engine:
  • A digit indicating the platform size or class
  • A digit indicating the generation or evolution

An additional + suffix indicates a long-wheelbase variant.

Modular component systemsEdit

In 2007, Volkswagen Group introduced a more flexible "modular component system" architecture on which to base future platforms. Four such component systems were planned:[4] However, models developed from these modular component systems may also be identified by PL/PQ platform designations.

  • MQB: Modularer Querbaukasten, or "modular transverse component system", for transverse engined, small to medium-sized cars.
  • MLB: Modularer Längsbaukasten, or "modular longitudinal component system" listed above, for medium-sized and larger longitudinal engined models.
  • MHB: Modularer Heckbaukasten, or "modular rear component system"), for rear-engined city cars. This platform was reportedly cancelled in 2008, and the projected MHB-based models will be based on a front-engined platform, New Small Family (NSF) instead.[5]
