The Volvo P80 platform was a Swedish mid-size unibody automobile platform developed and produced by Volvo Cars. It was in use from 1991 to 2005. It is designed for different wheelbases in front-wheel drive configurations and was adapted to all wheel drive. It debuted with the 1991 Volvo 850 and again in autumn 1996 with the Volvo 850 AWD. Although heavily modified by TWR, the same basic chassis was used as the underpinnings for the C70. After the model year 2000 most P80 models were replaced by their P2 successors, with the exception of the C70 convertible which remained in production until 2005. A total of 1,360,522 cars based on this platform were build.
