Continued from Toyota Releases 'Supra' Sports Car (2)

Electronic control improves driving performance

All of the three models come with advanced preventive safety technologies as standard features. They are equipped with "Pre-crash Safety," which helps avoid collisions or reduce damages by detecting pedestrians, etc. For its sensor, a milliwave radar device and monocular camera were combined.

Moreover, the new Supra features (1) "Blind Spot Monitor," which detects vehicles running in the blind spots of adjacent lanes, (2) "Radar Cruise Control (having a function to follow a vehicle at all speeds), which helps follow a preceding vehicle, and (3) "Lane Departure Alert," which helps control the steering wheel when the vehicle is about to depart from the lane.

Toyota equipped all of the models with the DCM on-vehicle communication system as a standard feature to provide a "connected service" dedicated to the Supra.

To improve driving performance, the company newly employed a suspension designed for reducing unsprung weight and improving rigidity at the time of assembly. The front suspension is a double-joint spring strut type while the rear suspension is a multi-link type.

For the RZ and SZ-R, an electronically-controlled suspension called "Adaptive Variable Suspension System" is used. It can control the attenuation rate of the shock absorber in accordance with driving mode and road surface conditions.

Furthermore, an electronically-controlled active differential was adopted to improve turning performance and stability. Working in conjunction with a VSC (vehicle stability control) system, it uses an electronically-controlled multi-disc clutch to steplessly control the locking ratio between the right and left rear wheels in the range from zero to 100. It keeps an optimal locking ratio for the differential gear at the time of running in a curve.
