F1 Championship why not use pure electric cars

Lei feng's network (search for "Lei feng's network", public interest): the author knows the @shadow Ma, veteran F1 fans, sports fans.

F1 does not use pure electric for many reasons (sounds, even the sense of pure driving, speed), but the most important reason, and civil electric cars cannot actually universal, is battery life problem.

We were recently very popular Tesla is confused and I do not deny that s is a sports car Model, I personally think it's significance in the field of electric vehicles is very large, possibly meaning close to the iPhone in the mobile space. But in fact, Model s does not change the nature of the electric car-the battery life is short.

Battery life is short

Maybe you need to refute, not a short, 500 km! Yes, it's not short, close to ordinary gasoline car. But one thing should not be overlooked that Model s is a 2-ton large car batteries for 600kg, make a reference to it the weight more than the Mercedes-Benz s-class and Audi A8 (some models) of weight. But the Tesla interior is the poor (that is, not much weight).

We come to do a calculation, 2014 F1 to run a race of about 300 km, fuel restriction 100kg (that is, 125L). If we consider the drive Model s energy and Mercedes-Benz s-class, or at least to 10L fuel per hundred kilometers. Model s-500km life 50L fuel: 600kg equivalent 50L the battery pack, then supporting an F1 needs some 600* (125/50) =1500kg battery packs. Was not considered because of battery weight and additional drivers.

So what reality is it? F1 F1 weight required in 2014 (gas + rider) lower limit is 700kg, is a lower limit, was afraid of some riders the devil to lose weight, or rich through the burn using expensive lightweight material picking on a team (the huge gap between F1 teams, without the protection money, F1 will become more and more money in the end no one basically play). So most of the fleet is able to easily achieve this lower bound.

In other words, in order to maintain the current F1 watch cases, two times the battery weight is closer to the present racing! Not to mention at this weight, how to ensure flexibility and performance, even the battery safety is also an issue.

Another is to look at, the FIA Formula e Championship is being organized, maximum 320kg battery results every race because of insufficient power in the middle of another car. Weight has reached the amazing 888kg, basically formula car Queen! (See Formula E-Official FIA Formula e Championship).

Output power Vera Bradley case

Another very important reason is that the electric power output is very small, which means that their speed is not enough. This is EV torque/power output characteristics: starting torque (power), but because there is no transmission, torque is declining, and low battery limit the output power. While the engine is in its infancy cannot achieve full power output, but more powerful. Vera Bradley iPhone 5S case

Model s so awesome 4.2s km speed, total power of only 410hp. In contrast, 1/4 miles in a straight line in the Model s beating Corvette Stingray (businessinsider.com page). Which has almost 300kph 662hp horsepower and top speed (comparison Model s 200kph). You can imagine, regardless of the mileage question F1 speed drop is absolutely intolerable.

Engines ROAR

Of course, F1 engine ROAR has been as a major selling point in F1. Visited the scene certainly knows that in that kind of environment, outside the track also could hear the engines ROAR around the track inside basic language is called (or far away). Taking into account the equation of electric sound (can go to the above Web site to watch videos), this indeed has largely disappeared.

Hybrids are the future

Actually the top car, top civilian car try hybrid.

Introduction of KERS system such as F1 in 2009, the so-called Kinetic Energy Recycle System, kinetic energy recovery system. In the year prior to the system and principle of the Toyota Prius is the same. 2014 of the kinetic energy recovery system with a layer, kinetic energy is realized with Turbo heat the intervention and management, see (2014, new era of energy recovery).

While most of the 24 hours of Le Mans racing with hybrid system; of new super sports car the three Musketeers was seen as P1,LaFarrari and 918 is a hybrid.

This is due to the powerful torque of the motor during the starting phase decisions. In 2014, F1, 600hps of amazing horsepower gasoline engines, but can only offer around 300Nm of torque, compared with peak power of motor for 170hps, but with 375Nm of torque. This is a crucial issue for F1 racing out to speed up!

It can be said that while F1 has become all electric not reality, but a hybrid (hybrid here not to save oil, but in order to get the torque of the motor starting stage against Heaven) has become the ultimate sports car/formula required the track equipment.
