Engine, Performance, and Driving Feel
Under the hood, the 2006 Mercedes CLS500 featured a 5.0-liter V8 engine that produced 302 horsepower and 339 lb-ft of torque. This powerful engine was mated to a 7-speed automatic transmission, which was a fairly new technology at that time. The car could accelerate from 0 to 60 mph in just about 5.9 seconds, offering a thrilling ride that was rare in luxury sedans back then.
Even though it’s over 15 years old, the driving dynamics still feel solid. The suspension system is air-based (called AIRMATIC by Mercedes), which delivers a smooth and balanced ride. Whether you’re cruising down the highway or taking a tight turn on a mountain road, the car stays controlled and responsive.
Timeless Design That Still Impresses
When the 2006 Mercedes CLS500 debuted, it was praised for its design. It introduced the world to the “four-door coupe” idea. This car has a low roofline like a coupe but the practicality of a sedan. The long, flowing lines and aggressive stance gave it a unique presence on the road.
Inside, the cabin is dressed in premium materials like leather, wood, and brushed metal. The seats are spacious and supportive, and the controls are laid out in a driver-friendly manner. Although the rear headroom is a little tight because of the sloping roof, the overall interior feel is elegant and premium.
Technology and Features
The 2006 Mercedes CLS500 was ahead of its time in terms of luxury features. It came with a Harman Kardon premium sound system, dual-zone climate control, navigation, power-adjustable front seats with memory, and keyless entry. It even had an early version of adaptive cruise control, which was rare at the time.
The car also included safety features like Electronic Stability Program (ESP), multiple airbags, Brake Assist System (BAS), and optional Distronic adaptive cruise system. Mercedes was always known for building safe vehicles, and the CLS500 is no exception.
Real Ownership Experience
People who own the 2006 Mercedes CLS500 often talk about how it makes them feel. It’s not just a car; it’s a statement. Owners love the engine note, the luxury ride, and how people still give it attention on the road. However, like many older German cars, maintenance can be costly. AIRMATIC suspensions and electronic components can sometimes require repairs. But most agree it’s worth every penny for the experience it delivers.
Many enthusiasts still seek out well-maintained CLS500s today, and forums like MBWorld.org are full of helpful advice and restoration stories.
CLS500 in the Used Car Market
Right now, you can find the 2006 Mercedes CLS500 on the used market for anywhere between $6,000 to $15,000 USD depending on condition, mileage, and service history. If you’re buying one, make sure to check for common issues like air suspension problems, engine oil leaks, and faulty electronics. A certified mechanic’s inspection is highly recommended before purchase.
Despite these potential drawbacks, this car is still a solid choice if you want luxury and power without spending new car money. And it’s also becoming a bit of a classic, which means it could even increase in value with time if kept in great shape.
