Formula 1 will undergo some fundamental changes in 2014 as the category bids to make itself more relevant to production cars. The FIA released its Technical
Regulations shortly before the German Grand Prix at the end of July. Externally, the cars will undergo some minor aerodynamic changes, such as a reduction in front wing width to 1650mm (from 2000mm) and the removal of the growing collection of brake duct winglets.
It’s under the engine covers, though, that the major changes will take place. A large number of material specification changes will remain largely invisible, but a whole new powertrain formula will be employed. The new engines will all
be 1.6-litre turbocharged V6s and, with highly restrictive regulations, their design will necessarily be similar. The bore, for example, is to be restricted to 80mm +/-0.1mm, whereas
under the current 2.4-litre V8 regulations teams are allowed any bore size up to 98mm. On the upside, bore spacing will no longer be restricted.
Only a single turbocharger will be permitted for pressure charging, but electronic turbo compounding is allowed.
there will be restrictions. Only FIA-approved injectors and fuel pumps can be used, though it is not clear if teams will have to have the components approved ahead of use in the same way NASCAR teams do, or whether they will use a single, spec design. As is the case this season, the
This forces all teams to
employ energy recovery and hybrid (KERS) systems
However, the layout seen on the mono turbo Audi R18 is outlawed as the regulations specify that the exhaust gasses may only exit the engine outboard of the cylinder heads and specifically not through the central v. Variable geometry turbochargers will not be permitted. All of the engines will be direct injection, but here too
engine’s crankshaft position and c of g height is tightly fixed. The weight limit will be
increased by 20kg to 660kg, largely to accommodate the extra energy recovery systems fitted to all cars. Instead of a 60kW KERS system, which can only be deployed for around seven seconds a lap, a much larger 120kW system will be introduced.
Use of the V6 engine in the pit lane will be outlawed, meaning all cars will have to rely solely on electric power during pit stops and other runs along pit road. The energy storage medium itself is left up to the teams, but other regulations essentially limit the systems to batteries or capacitors. Critical amongst these is a rule that states that the energy storage unit should weigh between 20kg and 25kg. The storage must also be housed in the car’s monocoque, outlawing layouts such as the one found on this year’s Red Bull RB7. Teams will still be restricted to a single electric motor generator unit. Unsurprisingly, F1 bosses
have said there needs to be further discussion before they will be completely happy with the new ideas. Ferrari team principal, Stefano Domenicali, said: ‘There are some manufacturers that are keen to go ahead with this project. Some others fear that,
