Cadillacs best-seller was redesigned for 1994. The base model was called Sedan DeVille, while the top-of-the-line version earned a DeVille Concours designation. Both were 4-door sedans built on a 113.8-inch wheelbase. Overall length grew by 3.4 inches compared to 93 sedans. No more Coupe DeVilles, Touring Sedans, or Sixty Specials made the lineup. Base DeVilles used an overhead-valve, 4.9-liter V8 engine. The Concours came with Cadillacs potent 270-horsepower, 4.6-liter Northstar V8 and Road Sensing Suspension. That RSS setup adjusts firmness in milliseconds, based on vehicle speed and road conditions. Regular DeVilles had a Speed Sensitive Suspension, which adjusts firmness to one of three levels, based on car speed. Antilock all-disc brakes were standard. Outboard front seatbelts got a height-adjustment feature.
