Few cars can match the cachet of a Mercedes-Benz S550. And with good reason. Introduced in 2005, the current-generation S-Class continues a long tradition of superbly engineered luxury sedans that provide a serene environment for high-speed travel. With nearly 400 horsepower, an S550 can manage the sort of top speed you expect from a supercar.
But it also boasts some of the most advanced safety technology seen in any car on the market. Pre-Safe, for instance, predicts a crash and optimizes the seats, windows and seatbelts to minimize injuries; Attention Assist, meanwhile, detects drowsiness and alerts the driver to erratic speed or lane control.
