Volvo also entered the British Touring Car Championship in the 1990s with Tom Walkinshaw Racing. This partnership was responsible for the controversial 850 Estate racing cars, driven by Rickard Rydell and Jan Lammers and with a best qualifying placing of third and a best race finish of fifth, which was only rendered uncompetitive when the FIA allowed the use of aerodynamic aids in 1995. TWR then built and ran the works 850 Saloon, with six wins in 1995, and five wins in 1996, and a S40, with one win in 1997 in the BTCC, as well as Volvo placing third in the Manufacturers Championship, both in 1995 and 1996. In 1998, TWR Volvo won the British Touring Car Championship with Rickard Rydell driving the S40R.
