Despite a lack of crash-test data from either the National Highway Traffic Safety Administration (NHTSA) or the Insurance Institute for Highway Safety (IIHS), an abundance of active and passive safety devices earn the 2008 Mercedes-Benz CLK-Class a near-perfect score from TheCarConnection.com.
Cars.com reports that all Mercedes-Benz CLK-Class models "have four side-impact airbags...front-seat side-impact airbags in [Mercedes-Benz CLK-Class] Cabriolets provide head and thorax protection, while [Mercedes-Benz 2008] Coupes have full-length side curtain airbags, [while] antilock brakes and an electronic stability system are standard."
Edmunds notes that Mercedes-Benz 2008 "rear side airbags on convertibles are optional," although they are standard on the CLK63 AMG, and "pop-up roll bars behind the rear seats that deploy in a roll-over are standard."
Drivers of the 2008 Mercedes-Benz CLK-Class enjoy an exceptionally clear view behind the wheel; according to Kelley Blue Book, "the absence of a center pillar between the front and rear window on each side...improves active safety by allowing an unobstructed view, with the windows in place or lowered." As for the Mercedes-Benz CLK-Class convertible, Edmunds reports that it "features large side windows and a relatively slim roof design for good top-up visibility."
