Driving Impressions
Although large in size, the 2010 Cadillac STS sedan feels three-fourths its size when driven with enthusiasm -- yet it rides like a supple luxury car when you're gobbling up miles on the highway. Cadillac offers an optional Magnetic Ride Control suspension that includes Touring and Sport modes.
