James Allen about possible tactics teams in Grand Prix Russia
Sochi Track is a new track built in the Olympic Park that hosted the winter Olympic Games 2014. It's a street track, somewhat reminiscent of Singapore or Valencia, but with more high-speed sections and curious protracted left turn at the first sector, where large load on the right front tire.
The circle is the third longest in the season, this indicator Sochi second only Spa and Silverstone, the configuration includes 18 turns and 12 zone of inhibition is almost perfect for energy recovery. In the era of V8 engines, the fuel consumption would be high enough, but the new power plant will easily fit into the limit of 100 kg of fuel for the race.
Without lingering left turn could be talking about a relatively average tire wear, but it is on Friday the team will try to gather maximum information to understand how well the behavior of cars on a real track meet their calculations and what distance the race will withstand the tires, especially the front right tire.
For the sixth time during the season, the Pirelli will offer teams the "average" couple of trains - Medium and Soft, relying on two pit stop in the race. The question is whether this strategy is the fastest, provided that for each standard pit stop will take about 21 seconds. Check in the boxes rather tricky, so this factor requires clarification.
Two zones DRS will provide racers two possibilities for overtaking on each circle with two lines, before the second and the 13th turns.
Sochi. 53 circle on 5853 m 309.732 km 18 turns. Aerodynamics is configured at a high level of clamping force.
The maximum speed of 320 km/h, the average speed of 200 km/h With a fully depressed accelerator pedal riders passing for 56 of the distance of the circle. Time for braking - 10 range. 12 zones of inhibition. Brake wear is medium.
The balance of power
Grand Prix Russia - 16th stage of the 2014 world Cup. Racers Mercedes has won 12 of 15 last Grand Prix. Lewis Hamilton won eight victories, Nico Rosberg - four. This weekend the team can advance to win the Cup of designers for the first time since 1955.
Tires and other factors
In Pirelli chose the compositions of the Soft yellow markings and Medium white markings - this year, this combination has been used five times.
Asphalt in Sochi mildly abrasive, but since it is brand new, the surface will be oils - this is normal, but at first the machine will slide. In winter, these oils will leave next year grip will improve. On the road quite a lot of acceleration, therefore, possible degradation of the rear tyres due to longitudinal loads.
One of the key factors in developing the strategy of the race - the difference between the compositions according to the time of the lap. When was the last time you used a pair of Medium - Soft, it was in the Grand Prix of Belgium, softer tires were faster at 1.6 seconds and became the main race of the race. At a longer range in the Spa, they withstood 16 laps in Sochi must be able to withstand more.
The condition of the road during the weekend will improve dramatically. On Friday the team stronger grip the car to the track, and then will gradually reduce downforce. On Friday, the difference between the compositions may exceed two seconds, so in the second session many people may refrain from traveling in the first half of the session to pass a series of laps on the soft compound tyre at the moment when the track condition will improve.
The number and the probable time of pit-stops
In Sochi is very tricky-in boxes, but the simulation says that the pit stop will take about 17.5 seconds plus the service time of the machine. It is difficult to judge about the tire wear, probably, the race will take place with two or three pit stops.
The probability of driving safety
Stages of Formula 1 in Sochi Circuit has not yet been conducted, there are no statistics, but after the accident Jules Bianchi in Suzuka FIA can more closely approach the decision to exit the vehicle security if incidental, moreover, that in some areas the trail is surrounded by barriers, which complicates surgical evacuation of cars. As a result, the probability of driving safety on Sunday is very high.
