The automotive world is full of unique creations, vehicles that blend different concepts to forge something new. Like mythical creatures combining different animal parts, the 2009 Mercedes-Benz CLS-Class emerged as a fascinating hybrid: a “four-door coupe.” Specifically, the 2009 Mercedes-Benz CLS550 model masterfully merges the elegant silhouette of a two-door coupe with the practicality and space of a luxury sedan. This isn’t some automotive myth; it’s a very real and desirable machine.
Mercedes-Benz offered two compelling versions of this groundbreaking vehicle: the CLS550 and the high-performance CLS63 AMG. The 2009 Mercedes-Benz CLS550 is built upon a stretched E-Class platform and is powered by a potent 5.5-liter V8 engine, generating a robust 382 horsepower. Beyond its impressive powertrain, the CLS550 boasts striking, coupe-inspired exterior styling and is equipped with advanced technology, notably the Airmatic semi-active suspension system. This sophisticated suspension dynamically adjusts to minimize body roll, dive, and pitch, especially when navigating challenging, winding roads. The result is a driving experience that is surprisingly engaging and almost as sporty as a smaller, dedicated coupe.
For those seeking even more exhilarating performance, the in-house tuning experts at AMG took the 2009 Mercedes-Benz CLS550 as their starting point and elevated it to an entirely new level with the CLS63 AMG. The already powerful 5.5-liter engine was swapped out for a monstrous 6.2-liter V8, unleashing a staggering 507 horsepower. This immense power is channeled through a seven-speed AMG SpeedShift automatic transmission, offering lightning-fast gear changes via steering wheel-mounted paddles and automatic throttle blips during downshifts. AMG also enhanced the chassis with optimized springs and shocks, larger, more powerful brakes, a throatier exhaust system, and more aggressive performance tires. These upgrades transformed the CLS63 AMG into a true performance machine.
The unique “four-door coupe” design of the 2009 Mercedes-Benz CLS550 does present a few minor compromises, primarily due to its sleek, sloping roofline. This stylish profile does result in slightly reduced outward visibility and limited rear headroom compared to a traditional sedan. Additionally, the coupe-like doors are longer and may require a bit more space for entry and exit in tight parking situations. However, these are minor trade-offs, and it’s unlikely that anyone captivated by the distinctive and alluring shape of the 2009 Mercedes-Benz CLS550 will find these points to be significant drawbacks.
Since its inception in 2005, the Mercedes-Benz CLS-Class pioneered the four-door coupe segment and has largely remained unchallenged in its unique niche. While some might argue that the 2009 Mercedes-Benz CLS550 and CLS63 AMG occupy a somewhat ambiguous space between coupe and sedan, there’s no denying the undeniable appeal of this stylish and potent Mercedes-Benz. It’s a cool and innovative creation that continues to be admired for its groundbreaking design and luxurious performance.
