2018 Mercedes-Benz AMG CLS 63 S Engine

“The 2018 Mercedes-Benz CLS features powerful engines and engaging handling, making it a fun car to drive. It also delivers the smooth ride you want from a high-end luxury sedan. Fuel economy numbers could be a little better, but they’re not bad for the class.”- cars.usnews

Engine and Transmission

The Mercedes-Benz AMG CLS 63 S gets a 5.5 L Twin Turbocharged Premium Unleaded V-8 Engine which delivers a power of 577hp @ 5500rpm and a staggering torque of 590 lb-ft @ 1750-5000rpm. Much like its competitors, the engine has slightly greater fuel intake capacity. In terms of engine performance, the Porsche Panamera Turbo does better but with an additional price of nearly 40,000$ which makes the Porsche lose out against the Mercedes-Benz AMG CLS 63 S.

The transmission is another AMG specific creation of Mercedes-Benz called the AMG SPEEDSHIFT MCT 7-Speed Automatic Transmission with a drive configuration of AWG Performance 4MATIC All-Wheel Drive (AWD) so the immense power gets driven to all its wheels to provide an optimum driving experience.

The Mercedes-Benz AMG CLS 63 S provides a mind-blowing acceleration of 0-60 mph in 3.5 seconds owing to its torque. Its acceleration is the best in its class and gives a sporting feel to the driver. With a quarter mile in just 11.6 seconds, the Mercedes beats its competitors even with a neck to neck competition with the Porsche Panamera Turbo.

Ride and Handling

Just like a human mind has different moods it operates on, the Mercedes-Benz AMG CLS 63 S provides switching between multiple modes for your different moods. It has 4 modes: Comfort, Manual, Sport, and Sport+

All the modes differ in terms of the power generated by the engine depending on the driving circumstances. A city ride with frequent starts and stops calls for the comfort mode which keeps the monstrous engine in a calm state. On free roads, however, engaging the manual mode to ensure your choice and demand of power. On highways and your favorite roads, the sport and sport+ mode comes in handy which unleash the true potential of the Turbocharged Engine.

All this with an integrated safety and stability systems ensure a controlled ride. Adjustable AMG Adaptive sport suspension settings available at a click of a button give you a total control of the car on varying road conditions. On top of that, the Electronic Stability Program (ESP) and the 4-Wheel Electronic Traction System (ETS) gives a safe ride even at high speeds without any bothering turbulence. The gear shifting also takes place at the immediate shift paddles on the steering wheels for faster response.


With immense torque comes an immense responsibility to stop the car and avoid collisions which call for a futuristic braking technology. Anti-Lock Braking System (ABS) as we all know has been there for ages, but the Mercedes provides something called as the Adaptive Braking Technology and Braking Assist (BASS) which basically eliminates the human error of not braking with the proper force and on the proper time. This significantly reduces the braking distance and any future collision possibilities giving the passengers a carefree ride at top performances.

Brake Front(in) 14.2 15.4 16.1 13.7
Brake Rear(in) 14.2 14 15 13.6
Curb weight(lbs) 4420 4497 4398 4430
60-0 MPH (ft.) 113 101 111 108

The braking distance for a deceleration from 60-0 mph happens to be 113 ft which are considerably greater than the competitors. Though the braking technology assists the driver, a little care is of utmost importance.

2018 Mercedes-Benz AMG CLS 63 S Fuel Economy

The fuel efficiency of 19 miles per gallon (mpg) of the Mercedes-Benz AMG CLS 63 S takes a hit against the Porsche Panamera Turbo’s 21 mpg considering both city and highway rides combined. Audi RS7 has an equal combined fuel economy but better highway fuel efficiency and lesser city fuel efficiency, so a riding choice can be made in that case depending on whether you would be frequent on a highway or city like conditions.

With every mode, there’s an option to switch on/off the ECO mode which helps improve the fuel efficiency. On an average, the fuel efficiency of the Mercedes-Benz AMG CLS 63 S isn’t that bad and can be an acceptable parameter.

2018 Mercedes-Benz AMG CLS 63 S Interior

“The 2018 Mercedes-Benz CLS delivers the swanky interior you want from a luxury car, but the design looks a little dated. Still, the cabin is stylish, well-built, and comfortable. The front seats are supportive, though the rear seats are cramped. The trunk is small for the class.”-cars.usnews

Seating and Comfort

A passenger capacity of 4 adults would’ve been a concern but every competitor has opted for the same model and hence it does not pose an issue. The car feels spacious and beats its match hands down with a large passenger volume of 104 ft-cube which gives more room for movement.

2018 Mercedes-Benz AMG CLS 63 S Exterior

“If it’s dramatic lines and exotically stamped sheet metal you seek, in an E-Class-sized body, the CLS is the only game in town. While rival coupe-like sedans and hatchbacks trim away excess detail, the CLS collects them all as it sweeps past its three-pointed star, framed as it is by a smartly textured grille and slim LED lighting.”- carconnection

Dimensions and weight

The ground clearance is also less which makes it stick to the ground for a better high-speed drive without any lift.

Mercedes Benz AMG CLS 63 S vs Porsche Panamera Turbo

Porsche Panamera Turbo was the only model with at par ratings and numbers as the Mercedes-Benz AMG CLS 63 S. Even though it performs better in many aspects, the exorbitantly high price of $150,000 leaves it in dust in front of the Mercedes Benz AMG CLS 63 S. Rather than investing an extra $40,000 into buying the Porsche Panamera Turbo, it’ll be wise to invest in the additional optional features that are offered by the Mercedes in its model, which only brings it closer to perfection.

The new Audi RS7 Sportback comes powers by a V8 bi-turbo powertrain delivering 560 hp and a peak torque of 553 lb.ft.

2018 Mercedes-Benz AMG CLS 63 S Final Verdict
