With the raft of significant technical changes due to be implemented next year, the 2014 Formula 1 season promises to be one of the most interesting in many years.
Here's an overview of the most important of the Technical Regulation changes coming to F1 in 2014:
(There are also a large number of changes to the Formula 1 Sporting Regulations due to be introduced in 2014 (including permanent driver numbers and double race points for the final race of the season) which I'll cover in a separate post.)

Or "power units" or "power trains" as we're being told to call them. Probably the biggest change to the formula in years.
The 2014 season will see the introduction of a new engine formula, with turbocharged engines returning to the sport for the first time since 1988.
The new engines will be a 1.6 litre V6 turbocharged format with an 8-speed semi automatic gearbox.
The engines will be limited to 15,000rpm and individual engine units must last for at least 4,000km (2,500mi) before being replaced (compared to the pre-2014 engines, which needed to last for only 2,000km (1,200mi).
KERS Morphs Into ERS-K
Or as it'll now be known: ERS-K.
The Kinetic Energy Recovery System will be incorporated into the design of the engine and its usage increased.
Its function as a supplementary power source will be taken by the introduction of the heat-based Energy Recovery System (ERS). The ERS unit captures waste heat as it is dispelled from the exhaust turbocharger, using an electrical device known as a Heat Motor Generator Unit.
This waste heat is stored as an electrical charge until it is utilised by a complementary system called the Kinetic Motor Generator Unit. This device is connected directly to the drive train to deliver the additional power in the most direct and efficient way.
It will give drivers an additional 161 bhp (120 kW) for thirty-three seconds per lap, compared to the KERS units used prior to 2014, which gave drivers 80 bhp (60 kW) for just six seconds per lap.
Electronic Braking Systems
Teams will be able to use electronic braking devices to manage the braking of the rear wheels as the increased power output of the ERS-K units will make controlling brake bias much harder.
Nose Jobs For All
The 2014 regulations require the use of significantly lower noses than in previous years (supposedly "in the interests of safety").
The front end tip of the cars' nose will have to be no more than 185mm above the ground (compared to the 550mm allowed since 2012).
The new regulations also completely outlaw the use of the "stepped noses" used in 2012 and 2013. This will force teams to design a car with a genuinely lower.
Narrower Front Wings
Most of the originally planned rules affecting downforce control and bodywork changes were abandoned late in 2012. This initially included narrower front wings.
The planned reduction in front wing width was however reintroduced, and the 2014 regulations reduce the allowed front wing width from 1,800mm to 1,650mm.
As part of the "F1 Goes Green" initiatives, and in order to promote fuel efficiency, fuel flow is restricted to 100kg/h above 10,500rpm. At lower revs a formula for the maximum flow must be applied based on the rpm in use.
The position of the exhaust outlet must now be angled upwards toward the rear wing instead of downwards to face the rear diffuser.
This will make the practice of using exhaust blown diffusers extremely difficult without major aerodynamic compromises.
Increase Your Weight Please
The minimum weight of the cars will increase from 642kg (1,420lb) to 690kg (1,500lb).
No False Camera Mounts
The use of false camera mountings is banned.
The practice of adding additional pieces of bodywork to the car in the place of camera mountings to take advantage of aerodynamic benefits is no more.
From 2014 only allow camera mountings may be used for cameras.
