Typical of full-size luxury cars, the CL-Class hasn't been crash-tested by the Insurance Institute for Highway Safety, but it does have a boatload of safety features. There are nine airbags, including two frontal ones, a side-impact torso bag for each of the four seats, side curtain airbags and a driver's knee airbag. Antilock brakes and an electronic stability system with traction control are standard. For a list of all standard safety features, click here.
