Mazda has been trumpeting its "gram strategy" to cut weight on all of its products, and the best example of how this philosophy works is in the new MX-5 GT race car. The roadster, which will compete in the Britcar MSA British Endurance Championship this year, weighs just 1,874 pounds while packing nearly twice the punch of the standard MX-5.
The heavily modified MX-5 engine produces 275 horsepower – enough juice to propel the light-weight roadster to 60 miles per hour in a scant three seconds flat. The race-ready Mazda can also crest 160 mph while looking damn fine with its new Spirited Green paint job.
In order to cut several hundred pounds off the base MX-5, the Jota Sport racing team removed interior components, revised other interior fittings and dipped the car's shell in acid. The doors, like many interior components, are made of carbon fiber and the windows are made of polycarbonate. The racing team also lowered the engine height, adjusted the suspension and added a six-speed paddle shift transmission to aid with handling.
