Infiniti Red Bull Racing provided a very handy guide to the changes that are taking place in Formula One ahead of the start of the 2014 season. The guide also includes a clip featuring Daniel Ricciardo and Sebastian Vettel who help explain the new changes to the Infiniti Red Bull Racing RB10.
Daniel races to catch up Sebastian in his 2013 World Champion’s car the RB9. As the two race along we see the 2014 regulation changes taking shape and coming to life, as the current World Champion’s car transforms from an RB9 into an RB10.
Changes that we are going to see in the move to new cars in 2014 include:
Racing on qualifying tires
How it worked in 2013: Drivers who made it to Q3 start the race on the tires with which they set their fastest lap in Q3.
How it works now: Drivers who reach Q3 start the race on the tires they used to set their fastest lap in Q2.
Why the change?: To make sure everyone goes out in Q3 rather than sitting it out and saving a set for the race. It’s very embarrassing when a huge crowd shows up on Saturday to watch cars stay in the garages.
How it worked in 2013: The nose was no more than 550mm above the ground (high nose).
How it works now: The nose is no more than185mm above the ground (low nose)
Why the change? Safety. The low nose is thought to be less likely to launch cars into the air in the event of an accident like Mark Webber’s at the 2010 European Grand Prix. The new designs aren’t as convenient for moving airflow under the car – hence the decision by many to extend their noses with the minimum allowable cross-section.
How it worked in 2013: Normally-aspirated 2.4l 90° V8 with standard injection
How it works now: Turbo-charged 1.6l 90° V6 with direct injection
Why the change? Downsized, turbocharged DI petrol engines are more economical and seen as the future of the automotive industry – and F1 is likes to be attractive to the automotive industry, who often provide it with shiny engines for less than cost price.
How it worked in 2013: 60kW KERS Motor-Generator Unit providing additional power for approx 6.6 seconds per lap
How it works now: 120kw MGU-K providing additional power for approx 33 seconds per lap.
Why the change? F1 wants 2014 cars to have the same performance as the V8s. The smaller engines produce less power so the cars need a bigger energy recovery operation to make up the shortfall. The new cars feature two recovery systems (ERS-K and ERS-H) and can supply 10 times as much energy per lap – but because the motor is twice as powerful, the hybrid system only supplies power for five times as long.
How it worked in 2013: Upward-pointing exhausts exiting either side of the rear bodywork
How it works now: Exhausts exiting down the centerline of the car
Why the change? Teams – particularly the one with Adrian Newey drawing the car – used the flow of exhaust gas to improve downforce. The FIA ruled this out and moved the exhausts. Teams hit back with ‘Coandă-effect’ exhausts which used sculpted bodywork to drag the flow back. The FIA, fed up with teams taking the pi… not entering into the spirit made the exhausts exit down the center of the car, coming out almost at the rear wing – where their effect will be severely curtailed.
How it worked in 2013: The minimum dry weight of the car + driver was 642kg
How it works now: The minimum dry weight of the car + driver is 691kg
Why the change? The new power unit is HEAVY! Far heavier than the extra 49kg. Everyone wants to hit the minimum weight because that means maximum speed, so they’re shedding weight any way they can – which is why drivers in 2014 make supermodels look like hippos.
How it worked in 2013: You put as much fuel in the car as you wanted and burnt it as fast as you could.
How it works now: There is a race limit of 100kg, and the maximum flow rate into the engine is 100kg per hour.
Why the change? New F1 is all about efficiency. This limit guarantees cars will be using about two-thirds less fuel. It’s such a simple message even the F1 press can understand it. The fuel flow limit, on the other hand, is there to stop teams getting too exotic with their ideas.
How it worked in 2013: 25, 18, 15, 12, 10, 8, 6, 4, 2, 1
How it works now: 25, 18, 15, 12, 10, 8, 6, 4, 2, 1 – except in Abu Dhabi, where it will be 50, 36, 30, 24, 20, 16, 12, 8, 4, 2
Why the change? Because no one watches F1 on TV when the Championships are decided early. Double points at the final race keeps the Championships alive for longer and more people watching.
