Cadillac Seville History 1999

The Seville, coming off a major redesign the previous year, returned with its two sedan line-up: Seville Luxury Sedan (SLS) and Seville Touring Sedan (STS). The car is three inches shorter than the old model and has a two-inch (5 cm) wider stance to enhance ride and handling. There is an extra 1.7 inches (4 cm) of headroom in the new model, and slightly more shoulder room. However, due to the shorter body length, there is a slight loss of rear leg room. The optional adaptive seating system detects pressure points and adjusts 10 strategically placed air cells in the seat cushion.

The Bose 4.0 sound system puts out nearly 425 watts of music power through its eight speakers, which include a 12-inch subwoofer. The Bose system is smart enough to automatically adjust volume and tone levels to compensate for changing cabin sound conditions.

Cadillac’s 4-speed automatic transmission features a Performance Shift Algorithm that analyzes your driving and adjusts the shifting appropriately. Hit the throttle hard and it duplicates the crisp shifts of a manual transmission. Accelerate gradually and the transmission shifts smoothly. Go through a corner under hard acceleration and the system is smart enough to delay shifting until you are through the turn, which improves handling balance.

For increased active safety, the Continuously Variable Road Sensing Suspension responds to changing road conditions to optimize ride and handling; it alters shock damping rates to find an optimal balance between comfort and handling.
