The WMSC has today confirmed that in addition to the optional budget cap of £40m that teams will not be allowed to re-fuel or use tyre warming equipment during a race. These changes are designed to cut the costs of transporting fuelling equipment and to encourage engine builders to come up with fuel-saving designs.
The WMSC stated that the amended 2010 Sporting and Technical regulations will be available shortly.
"Refuelling during a race will be forbidden in order to save the costs of transporting refuelling equipment and increase the incentive for engine builders to improve fuel economy (to save weight)," a statement read.
"Tyre blankets will be banned and that the ban on other tyre-heating devices will be maintained."
Re-fuelling during a race was made illegal in 1984 but re-introduced into the sport a decade later.
