Lane departure technology debuts

Cadillac STS / Overview / Lane departure technology debuts

Continuing Cadillac's commitment to using advanced safety features, the 2008 STS will offer new features including a new performance handling package; enhanced variable-effort steering with StabiliTrak on V-8 models; and new lane departure warning and blind side alerts.

The new performance handling package will be available for V-8-equipped rear-wheel-drive and all-wheel-drive models and V-6-equipped rear-drive models. The package includes 18-inch by 8.5-inch aluminum alloy, chrome-plated wheels fitted with new P255/45R18 Michelin Pilot Sport summer-only tires.

Brembo brakes with four-piston calipers provide enhanced braking, with front rotors measuring 14-inch by 1.2-inch (355mm x 32mm) coupled with 14.4-inch by 1.1-inch (365mm x 28mm) rear rotors. All four rotors are vented.

In addition to controlling brakes and reducing engine power, the latest iteration of StabiliTrak combines active front steering to turn the front wheels into the skid when rear wheels lose traction. The system includes a new steering motor assembly combined with computer-driven electronic controls that measure wheel slippage at all four wheels independently during acceleration, braking and adverse road conditions.

To help alert drivers to maintain their position on the road, the STS will be available with a new lane departure system. Controlled by a camera located in the rearview mirror that reads the lines in the road, the system will alert drivers when they have strayed into another lane. Drivers will get both audible and visual alert cues.

Another new feature is an available blind spot alert system. The radar-based convenience feature will provide drivers with a visual alert that appears on the outside rearview mirror when vehicles appear in a specified side zone.
