The FIA has released the technical regulations for the 2014 season, with innovative changes regarding the cars’ actions in the pit lane.
For a start, the cars will only be allowed to run on electrical power while in the pit lane, with no ignition or fuel supply to be engaged in the pits. Here is the breakdown of the changes:
Pit lane adjustments
As previously stated, one of the larger changes will be the introduction of electric-only F1 cars in the pit lane.
Self-starting motors will be mandatory on all cars, meaning that stalled cars can continue racing, as they will restart without outside assistance. This of course applies to stalls both in the pit lane and out on track.
Two energy recovery units
For the first time in motorsport, two different energy recovery units will be used at the same time. KERS will now be joined by the ability to recover energy from exhaust heat.
The KERS unit will not remain the same, however. Its power output will double, with 120kW being available.
It is currently unknown how much power the exhaust recovery unit will produce.
Expected engine changes
As expected, the engine in a Formula 1 car will undergo drastic changes. As previously reported, 1.6 litre V6 turbocharged engines will be used. The turbocharger must be inside the “V” of the engine (the 90 degree angle “V” shape remains for the engine), while the exhausts must be outside of the engine “V” area.
RPM output will be restriced to 15,000rpm, as opposed to the current 18,000 rpm.
A fuel flow limit will be introduced, restricting cars to 100kg/h (kilograms per hour). This goes with the FIA’s intentions to reduce dependency on fuel for the sport.
Weight and front wing adjustments
The minimum weight of the cars will be increased again – from 640kg to 660kg. This coincides with the much larger KERS and new exhaust recovery units, also taking into mind the reduction in engine size.
There will also be a minimum weight for all power units (engine, KERS, exhaust recovery) – 155kg. In previous years, only the engine was set a minimum limit of 95kg.
Current-generation “snowplough” front wings will become smaller, from 1,800mm wide to 1,650mm. This means that the front wing will no longer be wider than the width of the main car.
Eighth forward gear added
2014 will see 8-speed gearboxes in F1 for the first time. No fewer gears will be allowed.
The FIA also notes that:
"Each competitor must nominate the forward gear ratios (calculated from engine
crankshaft to drive shafts) to be employed within their gearbox. These
nominations must be declared to the FIA technical delegate at or before the
first Event of the Championship. For 2014 only, a competitor may re-nominate
these ratios once within the Championship season, in which case the original
nomination becomes immediately void. Ratio re-nominations must be declared as
a set and may only be effected by the substitution of change gears."
