At first, power troubled us for thinking about racing of future.
electric motor's sounds doesn't have enough punch because of getting heavier.
The hydrogen fuel power is inefficient, so we pay attention to HV(Hybrid vehicle) cars.
A hybrid vehicle is a vehicle that uses two that is both electric motor and engine power sources to move the vehicle.
You use the power that is lost when you stop for generation then, save it to battery and move an electric motor in low speed.
So it is said that the mileage improves and the discharge of the CO2 decreases,
and the environment improves getting better because there is less time to use the gasoline engine than a normal gasoline engine.
We paid attention to hybrid because the super car that was adopted the hybrid system with electric motor and high power engine was released in summer 2013 for example LaFerrari from Ferrari and P1 from McLaren.

We told that the torque which the electric motor has maximum power since it started was fitness for acceleration.
It is ideal and thought about environment such as the first step to the future because it entrusts engine during high speed area then uses the electro motor for acceleration from low speed.
It is later still more to be used widely that because two cars are around 100 million expensive cars. However, we expect most sports cars and super cars will has been such as the system.
In addition, in 2013 autumn, the hybrid super car, Porsche 918 spyder got the third prize at Nürburgring where the stock cars of most sports types attains time on the run and competes.

918 exceeded gasoline cars!!
And this 918, the mileage is realized 30km/L. It's near the greatly "Prius".
