Pit Stop – Part One of 2014 Season – By Lewis Brearley

It’s scary to think that by the end of this month, pre-season testing in Formula One will already be underway. It gives you a sense of the work rate needed by the teams to get their new cars made and transported to Spain just two months after they packed up their 2013 cars in Sao Paulo.

But this year the turnaround is even more complex than usual. The 2014 cars are designed to brand new technical regulations: new engines, new KERS, new exhausts and new aerodynamics.
When the teams turn up and unveil their new cars on 28 January down at Jerez, Spain a new era of Formula One will begin.

The biggest change will be the introduction of 1.6 litre, turbocharged engines – or “power units” as they are being termed – with much more powerful energy recovery systems than the 2013 cars.

The power unit will contain both a kinetic energy recovery system similar to the ones used in 2013, only more powerful, and a second system which will utilise waste power from the turbo. However, unlike 2013 this energy will be used automatically and not at the press of a button.

Furthermore this system will be restricted to using only 100kg for the entire race with a maximum flow rate of 100kg per hour meaning fuel efficiency may be almost as important as outright power.

Next, the requirement of a single exhaust exiting the centre of the car at an upright angle, eradicating practically all of the downforce derived from blowing the exhaust gases towards the diffuser – Red Bull’s specialty.

The other changes are aerodynamic such as a front wing 75mm narrower and, for safety reasons, a much lower nose. These will affect the flow of air around the entire car and therefore are perhaps much more important than they may first appear.

The decrease in engine power combined with the loss of aerodynamic downforce means the 2014 cars are almost certainly going to be slower than the 2013 cars, as was intended by the regulations. How much slower they will be is unknown however, but the pessimistic predictions of silent cars circling six seconds slower is probably rubbish.

Even if the pace of the cars is much slower, such is the pace of development at the top teams that they will soon close in on the speed of the V8 machines.

The truth is that no one, not even Adrian Newey at Red Bull or Pat Fry at Ferrari, knows what next season will bring and that’s why 2014 is so highly anticipated. By the end of this month the first piece of the puzzle will be in place.
