     Researchers in Britain are driving the environmental movement to a new level. A team from the University

of Warwick has built what it calls the world's first completely environmentally friendly Formula Three racing

car.

     The car is made mainly of renewable materials, like plants and vegetables. The structure around the car is

made from natural plant fibers and potatoes. The steering wheel (方向盘) is made from root vegetables like

carrots. The engine uses bio-fuel made from vegetable oil and waste chocolate.

     The new racing car is extremely fast. The car has a top speed of two hundred fifteen kilometers an hour.

And it can go from zero to ninety-five kilometers an hour in just two and a half seconds. The racing car meets

all of the Formula Three racing requirements except for its biodiesel (生物柴油) engine.

     Automobile racing is one of the most widely watched sports in the world. But it is also considered one of

the least friendly sports to the environment. Racing cars burn a lot of fuel, and create a lot of air pollution. In

recent years, the racing industry has taken steps to protect the environment. More racing companies are now

producing cars that use less energy. These cars produce less pollution than cars that depend on traditional fuel,

like gasoline.

     Last month, the new racing car was set to run in its first competitive race at the Formula Three

Championship Final at Brands Hatch. It would have been the first biodiesel-powered car to race at Formula

Three. Current Formula Three rules let only gasoline-powered car to compete. Officials needed permission

from all of the Formula Three racers for the biodiesel-powered car to compete. They were unable to contact

one of the drivers, so the new racing car didn't appear in the event. In test runs, the new racing car was the

fifth fastest among the Formula Three race cars. Supporters are hoping to have the fuel problem solved in time

to compete in the next season.
