Toyota's hybrid races into history

Back to the cutting-edge of racing cars!Last month, I reported to you(June 12th) the historical first bio-fuelled car win in a major British motorsport championship by the Aston Martin DBRS9.Following fast on the heels of my earlier report comes word of the Denso Toyota Supra HV-R which made history ,the weekend before,by winning the Tokashi 24-Hour race.With this feat,the Toyota became the first hybrid to win a competition.

Last year ,Toyota entered its first hybrid for the Tokashi.The Lexus GS450h made a creditable 17th place in the race.Based on the Supra GT raced in Japan's Supra GT events,this year's Toyota entrant took first spot.The Toyota engineers see such races as a development test bed for their production cars- the Toyota Prius uses a hybrid system- to achieve a lighter more efficient product.

Helping the Supra HV-R's hybrid system along were two technological advances.Firstly, instead of rechargeable batteries, a quick-charging capacitor system was incorporated.This was reckoned to be better suited to the repeated acceleration and deceleration necesssary under race conditions.Secondly,two electric in-wheel(front) motors, and one rear axle-mounted electric motor, enabled greater recovery of energy on deceleration and braking at high speeds.

The frequent technological advances which will continue to feed back into the production of cars for sale to the general public are extraordinary and exciting for future greener motorists.
