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:

  

MK4: 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. 

MK5 Jetta TDI White 2007 VW Rabbit 2006 VW GTI MK5

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.
