Home > What is MK4, MK5, etc.?
Many of the product listings on dieselgeek.com are described in terms of the generation of car or chassis type. To reduce confusion we created this page to allow you to determine what chassis type and generation your car falls into. Here's the breakdown:

Jetta, Golf, GTI and New Beetle This is the 4th generation "A" size chassis that applies to many of the products we sell. These cars are also commonly referred to "A4" cars but since we also sell products for the Audi A4 we prefer to call these cars MK4 which is a shortened version of Mark 4 or fourth generation. MK4 applies to Golf and GTI sold in the U.S. from mid 1999 through 2006 and Jetta sold from mid 1999 through 2005.5. The 1998-2010 New Beetle is also built off of the MK4 chassis. We sell skid plates as well as short shift kits for the 5 speed and 6 speed MK4 cars

MK5: Jetta, GTI and Rabbit This is the "A" chassis but now in the 5th generation hence the MK5 designation. In mid 2005 VW released the MK5 Jetta which replaced the MK4 Jetta in the U.S. (The MK4 Jetta station wagon and sedan was sold in Canada for the 2006 model year.) The MK4 Golf and GTI were replaced in mid 2006 by the Rabbit and MK5 GTI respectively. The MK5 Jetta sedan was continued through 2010. The MK5 GTI and Rabbit were sold through 2009. The MK5 Jetta SportWagen was sold from 2009-2010.

MK6: Jetta Sedan The MK6 Jetta sedan was released as a 2011 model. It is its own animal from a sheet metal and interior standpoint but it is indeed MK6 or 6th generation.

MK6: Golf and GTI The MK6 Golf and GTI were sold starting in 2010.

MK6: Jetta SportWagen The MK6 Jetta SportWagen got the same front end as the MK6 Golf and was sold from mid 2010 onwards.

MK6: 2012 Beetle These cars are based off of the latest and greatest 6th generation A class chassis.

A3: Jetta This was the 3rd generation Jetta that was sold from 1993- mid 1999. Also called the MK3 or MKIII.

B4: Passat This is the 4th generation of the B class cars (larger than the "A" class). This includes the 1995-1997 Passat.

B5: Passat and Audi A4 This was the 5th generation of the B class car. VW and Audi shared this platform to produce the Audi A4 and VW Passat. The Audi A4 used this platform from 1996 through 2001 and VW used this platform from 1998 through 2005. The
facelifted 2002-2005 Passat is also commonly called a B5.5.

B6 and B7: Audi A4 The B6 and B7 Audi A4 were refinements on the B5 chassis. The B6 and B7 A4's were sold from 2002 through 2007.

B7 Passat: This car was released as a 2012 model.
