With moveable rear wings, a new tyre supplier, the return of KERS, a 107 percent qualifying rule and more, there are plenty of regulation changes that will have a major impact on the Formula One field in 2011…
Adjustable rear wings
Under new moveable bodywork regulations, drivers of suitably equipped cars can adjust the rear wing from the cockpit, altering its angle of incidence through a set range. (The moveable front wing, used in 2010, has been dropped.) The system’s availability is electronically governed - it can be used at any time in practice and qualifying, but during the race can only be activated when a driver is less than one second behind another car at pre-determined points on the track. The system is then deactivated once the driver brakes. In combination with KERS, it is designed to boost overtaking. Also like KERS, it isn’t compulsory.
No F-ducts or double diffusers
Any system, device or procedure which uses driver movement as a means of altering the aerodynamic characteristics of the car is prohibited from 2011 - that means no F-ducts. Tightening of the regulations on stepped floors means double diffusers in their original sense are also banned.
KERS
A badge of honour for some, a bugbear for others on its debut in 2009, KERS - or Kinetic Energy Recovery Systems - have been reintroduced in 2011 after the teams mutually agreed to suspend their use in 2010. KERS take the waste energy generated under braking and turns it into additional power. This is then made available to the driver in fixed quantities per lap via a steering wheel-mounted ‘boost button’.The systems are essentially the same as those seen in ’09, with no increase in the maximum permitted power (though that could change in subsequent seasons). The challenge for the engineers this time round is packaging. Last time KERS was run, refuelling was legal. Now, with it banned, fuel tanks are larger and finding room to accommodate battery packs etc is not as easy. Hence don’t be surprised if bodywork has grown in places, relative to 2010. On the plus side, minimum car weight has been upped by 20kg to 640kg, meaning larger drivers don’t pay the weight-distribution penalty they once did in a KERS-equipped car.
