The rulemakers have announced the applicable weight restrictions for cars eligible to compete in the 2011 FIA World Touring Car Championship season, which will see two drivetrain configurations and three different engine configurations competing head-to-head.
Between front- and rear-wheel-drive powertrains, there is also the new-for-2011 1.6-litre turbo engine, or the older-spec 2.0-litre turbodiesel, or the 2.0-litre normally-aspirated engine.
Cars running the 1.6-litre turbo engines will run with a base weight of 1,150kg for front-wheel-drive models (the Chevrolet Cruze) and 1,170kg if rear-wheel-drive (selected BMW 3-series models).
Cars running the normally-aspirated 2.0-litre engine will run at 1,150kg if front-wheel drive (the Chevrolet Lacetti and SEAT León TFSI) and 1,155kg (older-spec BMW models).
Turbodiesel cars (the SEAT León TDI) will have an 1,170kg base weight.
All competitors will start the season with a further 40kg compensation ballast attached, above the base weights specified.
