2013 British Touring Car Championship season

The 2013 DunlopMSA British Touring Car Championship was a multi-event motor racing championship for production-based touring cars held across England and Scotland. The championship features a mix of professional motor racing teams and privately funded amateur drivers competing in highly modified versions of Family cars which are sold to the general public and conform to the technical regulations for the championship. It is one of the most popular domestic motor racing series in the United Kingdom, with an extensive program of support categories built up around the BTCC centrepiece. It was be the 56th British Touring Car Championship (BTCC) season.

This was the third season that cars conforming to the Next Generation Touring Car (NGTC) specification will be allowed to compete and the first season since the end of the phased transition from the Super 2000 specification which saw the organising body, TOCA, maintain a performance equalisation between the two chassis specifications. The season saw teams compete with car chassis built to either NGTC or S2000 specification although the NGTC cars had a significant performance advantage over the S2000 cars by giving NGTC cars a significant increase in the turbo boost pressures which they are allowed to run. Teams can choose to use the NGTC 2.0 litre turbocharged engine, or S2000 2.0 litre Naturally aspirated engine. Teams with S2000 cars were eligible for the newly introduced S2000 trophy named after the winner of the inaugural British Saloon Car Championship in 1958, Jack Sears, known as the Jack Sears Trophy, of which Sears himself awarded to the top S2000 finisher of the year – Lea Wood – at the final round at Brands Hatch based on the amount of S2000 wins (known as 'cups') over the season.
