TOYOTA INTRODUCES CELICA GT-FOUR
High-Performance Full-Time 4WD Passenger Car
with New Twin-Cam Turbo Engine
Toyota City―TOYOTA MOTOR CORPORATION today released the high-performance full-time 4WD Celica GT-FOUR for nationwide sale. The latest addition to the lineup of Celica specialty cars, it features a newly developed twin-cam turbocharged engine with water-cooled intercooler, as well as full-time four-wheel drive (4WD).
With full-time 4WD, driving power is distributed constantly to all the wheels. This system increases grip, giving the tires more bite than with ordinary two-wheel drive. The extra power provides greater driving force, ensuring better driveability and stability.
CELICA GT-FOUR
The Celica GT-FOUR has been designed as the top-of-the-line speciality car to satisfy customers' needs for higher quality automobiles. The new 3S Twin-Cam 16 Turbo engine embodies the latest in Toyota technologies and is the most powerful domestic 2-liter production engine. The full-time 4WD system with central differential has been tailor-made to handle the powerplant's impressive output.
Major Features of Celica GT-FOUR
- Full-time 4WD with central differentialWhen a car corners, not only the left and the right tires but also the front and the rear tires trace different paths of differing lengths. When a 4WD car without a centrally located differential makes a tight turn at a low speed on a level road surface providing good grip, a phenomenon called "tight corner braking"* occurs and impedes smooth driving. The Celica GT-FOUR's central differential absorbs the difference in revolutions between the front and rear axles to realize constant, smooth running. The Celica GT-FOUR's central differential also incorporates a locking mechanism.
- New 3S Twin-Cam 16 TurboThe new 2-liter 4-cylinder 3S Twin-Cam 16 Turbo (3S-GTE) was developed from the high-performance sporty 16-valve engine, the 3S Twin-Cam 16. Toyota's own turbocharger, a water-cooled intercooler and exhaust manifolds with independent ports were added to the base engine. The resulting engine produces maximum power output of 185 ps (JIS net) and maximum torque of 24.5 kg-m (JIS net), making it the most powerful 2-liter engine produced in Japan.The full-time 4WD and 3S Twin-Cam Turbo combine to make the Celica GT-FOUR one of the world's most powerful cars.
- Exterior Styling and InteriorThe Celica GT-FOUR features a large colored bumper and integrated air-dam skirt, round fog lamps, and large locker moldings. The rear license garnish and side extension panels match the color of the other exterior panels. The sporty styling combines the Celica GT-FOUR's beautiful streamlined surfaces and the dynamism of the 4WD.The interior emphasizes high quality. For the first time in a 2.0-liter car, for example, genuine leather has been partly used in the standard seats.
- Drive Train
- The suspension is based on the very popular 4-wheel independent suspension with struts that was used on the current Celica. The basic suspension system's components and geometry were thoroughly scrutinized and improved to produce a suspension system that complements a high-performance 4WD car with a powerful engine.
- The rear suspension units are connected through a subframe, realizing superior maneuverability, stability and riding comfort worthy of a high-performance 4WD passenger car.
- Tires provided as standard equipment are the proven Pirelli P600 radials (195/60R14 85H).
- *Tight corner braking
- When a car corners, a difference in revolutions is required between the front and rear wheels. When a 4WD car's front and rear axles are connected without differential gears, as is the case with a part-time 4WD car in the 4WD mode, the necessary difference in revolutions between the front and rear wheels is suppressed. As a result, the car slows down in a tight corner as if the brakes had been applied. This phenomenon is called tight corner braking.
