2003-2008 Mercedes-Benz CLK: Year-to-Year Changes

2004 Mercedes-Benz CLK: By the time the 2004 model year began, CLK cabriolets (convertibles) had adopted the styling that began with the redesigned true-hardtop coupes. Convertibles had a fully automatic power fabric top and a heated glass rear window. Roll bars in the rear headrests were designed to pop up if sensors detected an impending rollover. Both body styles came in three trim levels. CLK320s had a V6 engine, CLK500s held a 302-horsepower V8, and CLK55 models, developed by Mercedes' AMG performance arm, used a 362-horsepower V8. All models used a five-speed automatic transmission with manual shift feature. The CLK55 added manual-shift steering-wheel buttons. Antilock braking, antiskid/traction control, and front and rear side airbags were standard. The convertible's front side airbag covered the occupant's head and torso. Coupes also had head-protecting curtain side airbags. All V8 models had 17-inch wheels, which were optional on CLK320s, in place of 16s. CLK55 models had a sport suspension. CLK500 convertibles had exclusive AMG-designed trim. Mercedes' TeleAid assistance was standard. Rear-obstacle detection and Distronic cruise control were optional. For 2004, CLKs were factory-prewired to accept a newly optional dealer-installed satellite radio.

2005 Mercedes-Benz CLK: A seven-speed automatic transmission replaced the five-speed in the CLK500 series. For 2005, the CLK55 adopted 18-inch wheels. All models were mildly facelifted and gained a new center console.

2006 Mercedes-Benz CLK: 2006 brought no changes for the CLK.

2007 Mercedes-Benz CLK: New V8 engines trigger model-name changes for these four-passenger coupes and convertibles. Three 2007 models are offered. The CLK350 returns with a 268-hp V6. The CLK550 has a 382-hp V8 and replaces the 302-hp CLK500. The high-performance CLK63 has a 475-hp V8 and replaces the 362-hp CLK55.

2008 Mercedes-Benz CLK: The 2008 Mercedes-Benz CLK63 AMG Black Series made its debut as an ultra-high-performance addition to this premium sporty car's roster. It used the 6.2-liter V8 tuned to 500 horsepower.
