Mercedes-Benz does not shy away from tech for its top-tier cars; these vehicles have every new electronic feature the company can conceive. For the CL550, that means adaptive cruise control that can bring the car to a complete stop when traffic ahead halts, a split-view front LCD letting the passenger watch a movie while the driver views the navigation system, and night vision, which uses infrared projectors and a camera to show the driver the road on dark nights.
Although we've seen some of these features before in other Mercedes-Benz cars, the CL550 also debuts a new engine, a direct-injection turbocharged 4.6-liter V-8 replacing the 5.5-liter V-8. The new engine generates bucketfuls of power and slightly better fuel economy than the outgoing engine. But its sluggish low-speed behavior shows that Mercedes-Benz needs to do a little more tuning.
