Despite the fact that nowadays most of the car’s performance is predicted by merely working on a simulator and feeding in the numbers, yet nothing can substitute making the driver drive the new chassis taking it out for  a spin.  With many teams having already released their car and others doing so at the beginning of the test, all the teams except Force India and Caterham will take part in this test with their drivers taking the reins of the car on alternative days.

Starting February 1st, we’ll have all these teams with their drive   rs running their 2015 cars for more and more laps, taking out more and more mileage, trying different simulations and working with different fuel input, all in a bid to make sure that the actual performance of the car matches the one predicted in the simulator. A Formula One car involves loads of numbers and calculations. Any team for which the numbers from the run on the track matches the one predicted on the simulator, goes away happy and satisfied knowing that they’ve had a successful winter and their car is ready for Melbourne.

Apart from the power unit, aerodynamics and chassis, the track run is also very essential to predict the performance of the tyres as Pirelli will release its new rubber  for the 2015 season before the start of the testing.

Speaking of the track, the Circuit de Jerez is a 4.48 km track located in southern Spain. Since these tyres only work when they’re raised to a particular temperature, despite the winters, these tyres reach that high temperature easily since the surface of the track is an abrasive surface. But, this has a downside. Considering the surface, the teams are not able to run the softer compound tyres which only they’ll be able to use in the first race in Australia. Otherwise the track has an interesting layout with a good mix of slow and fast corners, thus helping the teams gather all the necessary information.

Although these test don’t give us a clear picture of the season shaping up, it does offer these teams a good idea of how their 2015 might shape up. A lot of eyes will be on the top 4 teams-Mercedes, McLaren, Ferrari and Red Bull who will aim to start their 2015 campaign in Melbourne on a high. Naturally what we will see here in Jerez isn’t the final structure of the car or a showcase of its performance.
