Buick’s exclusive “MaxTrac” option

Buyers could also opt for a MaxTrac system with ultimate computer-controlled power. MaxTrac was designed to help the driver gain better control of the car while driving on ice, rain water, and snow. With these road conditions, MaxTrac helped prevent excessive rear-wheel spinning by keeping the rear wheels under control.

When MaxTrac was turned on, a tiny computer would compare the speeds of the rear and front wheels. If a rear-wheel spin was detected, the computer would modulate the engine to give controlled power to the wheels, making it possible to take full advantage of all available traction on the road’s surface. MaxTrac was an exclusive Buick option that was also available on the LeSabre models with the 455 engine, the Estate Wagon, the Centurion, and the Electra 225 models.

J'ai trouvé une autre place qui explique le sensor dans la roue d'en avant et ca fonctionnais un peut comme les ABS des années 90 avec une roue dentelé dans le disque avec un speed sensor.

Et un speed sensor dans la transmission.
