You want to go back to the 1960s for the last time Formula A single knowledgeable such a basic change in its rules. Certainly, F1 in 2014 is a distinct formula, with highly productive new powertrains and slimline aerodynamics.
A fairly minuscule 1.6-liter turbo V6 engine with direct-fuel injection powers every single car. New principles mandate the engine cannot eat a lot more than 25 kilograms (220.46 lbs) of fuel each race, a 30-% reduction in contrast to final 12 months. There is also a 15,000-rpm rev restrict — still dizzying but not as significantly as the previous 18,000 rpm. This must prevent explosive ranges of qualifying turboboost. Horsepower is not minimize by a lot: The V6s make about 650 hp, and far more potent hybrid Energy Recovery Methods (ERS) harvest waste heat and kinetic energy. What was previously KERS is now ERS-K, with energy output doubled from 80 to 160 hp. Final year’;s V8s and KERS mixed made around 830 hp compared to the around 810 of this year’;s drivetrains. The battery retailer is 10 instances more substantial, capable of providing the full ERS enhance for much more than 33 seconds per lap rather than a minor significantly less than the 6.7 seconds per lap witnessed last year.
Also new is an ERS connected to the turbocharger ERS-H (H for heat) harvests vitality from the 125,000-rpm turbo, delivering electricity to both spin the turbo to decrease lag or divert power to the ERS-K motor, for higher duration to its increase. So, we’;ll have cars with the earlier peak and torquey electrical power delivery even though becoming fairly environmentally pleasant.
Safety is augmented with a low nose tip meant to prevent the kind of flip/airborne crash Mark Webber seasoned during the 2012 European Grand Prix. This adjust is most likely to catch the spectators’; eyes, as teams find techniques to maximize aerodynamics inside the new rules. Most teams have adopted an extending “finger” to kind the lower nose tip, while trying to keep the more substantial portion of the front-crash framework up out of the airflow.
Downforce is diminished by a narrower front wing and slimmer rear wing, the latter with out the lower wing element. The modifications deliver a double ¬¬whammy for the aerodynamicists: The front wing suggestions are now inline with the center of the front tires, the worst feasible area for generating downforce. Meanwhile, losing the rear wing’;s decrease element indicates the movement coming up from the diffuser does not connect with that from the best rear wing, reducing both devices’; effectiveness.
Exhaust-blown diffusers — a single of F1’;s most current gadgets the past few many years — are now banned, with the turbo engine blowing via a high-mounted single central exhaust pipe. This alone charges drivers a lot more than a 2nd per lap, so crew aerodynamicists have to operate additional tough to recoup all the losses delivered by these regulations.
Far more and far better cooling is important to the new powertrains (gasoline engine and hybrid ERS). Heat is created from the air compressed by the turbocharger, the red-scorching turbo itself and the electrical energy becoming transferred. These autos run hot — and dependability is an situation. The excess weight limit increases from 642 kilograms to 690 kilograms (1,415.37 pounds/1,521.19 pounds).
Grand Prix racing now has more effective cars, with a bit significantly less electrical power due to significantly less fuel and much less downforce. Lap instances will enhance initially, but assume these vehicles to quickly be as rapidly as ever thanks to F1’;s design geniuses.

1.6-liter V6 Engine Turbo Direct Injection: New engines are one.6-liter, 90-degree V6s. They are turbocharged and direct injected, with a 15,000-rpm restrict. Companies might not actually hit that in 2014 due to reliability worries. Horsepower from the engine alone should reach 650 total powertrain output is all around 810 when mixed with electrical assist from the power-recovery method. Just 5 engines, rather than 8, are permitted per driver for the season. Grid penalties apply for using a lot more. Fuel-Movement Limit: To handle energy and increase ranges, the fuel cannot at any time movement at a price exceeding 100 kg/hour. A particular new sensor has been created to check the fuel movement instantaneously.
Race 25-kg Fuel: Each and every automobile could eat a highest of 25 kg (130 liters, or 34.34 gallons) from the race start off to the checkered flag. Vehicles can carry further fuel to complete the parade and amazing down laps. This is about a third significantly less than last year.
ERS-K: What was KERS is now dubbed ERS-K (K for kinetic). As a car slows for a corner, the Motor Generator Unit (MGU-K) connected to the engine harvests the power from the Power Retailer. The water-cooled motor produces 160 hp.
ERS-H: New for 2014 is ERS-H (H for heat). An additional Motor Generator Unit (MGU-H) recovers energy from the spinning turbo when the driver is either on or off the throttle. This energy can be reused, either to spin the turbo back up to pace for greater acceleration, or through the Vitality Retailer to electrical power the MGU-K for far more power at
Power Retailer: A battery pack sits in a recess under the chassis the array of lithium-ion cells can supply 4 megajoules per lap. Special Management Units convert the AC energy created by the 2 MGUs to DC for storage in the battery.
Eight-Pace Gearboxes with Fixed Ratios: Gearboxes should now use 8 forward ratios (plus reverse), up from 6 final yr. The additional gear accommodates a new rule that says teams can only modify their gear ratios 1 time in the course of the season, rather than from track to track. This means drivers have the same ratios on, say, the slow-pace Monaco streets as on a high-pace circuit like Monza the torquier new powertrains must offset the lack of available ratios.
Narrow Front Wing: To decrease downforce, the front wing is narrowed 15 cm down to 165-cm wide. This locations the wing ideas appropriate in front of the tires, further minimizing prospective downforce. These narrower wings need to be significantly less susceptible to crash harm, specifically on the 1st lap of races.
Minimal Nose Tip: In order to stop autos flipping, the nose tip is lowered to 18.5 cm. Teams have discovered various ways to exploit the nose rule, from finger-shaped extensions to broad duck-bill patterns.
Reduced Bulkhead: An extra safety measure lowers the bulkhead that the removable nosecone attaches to, from 625 mm to 525 mm. This locations it reduced than the cockpit sides for enhanced safety in a T-bone crash.
Single Exhaust: Due partly to the turbocharged engine, but also to avert exhaust gas from blowing on the diffuser, the exhaust pipe is now limited to a single large, central outlet with a fixed diameter.
Shallower Best Rear Wing And No Beam Wing: Matching the front wing’;s diminished downforce is a smaller best rear wing, and its decrease beam-wing element is gone. Teams should exploit new solutions to recoup the misplaced downforce.
Rear Brake By Wire: Element of the new powertrain’;s bundle is the require for a rear brake-by-wire program, due to the new ERS’; elevated drag on the auto as it collects vitality beneath braking. It needs electronic modulation of rear-brake stress to sustain chassis stability. In the occasion the brake-by-wire method fails, a standard hydraulic backup method operates the rear brakes.
Tires: Due to the engines’; enhanced torque, Pirelli produced new, much more sturdy tires.
