Mercedes-AMG has revealed the new 53-Series models of the CLS, E-Class Coupe and Cabriolet in full, introducing not only a new model designation but the first AMG models to feature electrification as well.
The highlight of the new models is of course their powertrain, which is comprised of a twin-turbo 3.0-liter inline-six engine with 435hp and 383lb-ft (520Nm) of torque paired to an EQ Boost starter-alternator that can momentarily provide an additional 21hp (16kW) and 184lb-ft (250Nm) of torque.
The EQ Boost starter-alternator also feeds the vehicle’s 48-volt electrical system. A nine-speed AMG Speedshift TCT 9G automatic transmission sends the power to AMG’s fully variable Performance 4Matic+ all-wheel drive system.
AMG has fitted the new straight-six engine with one regular turbocharger and one electric auxiliary compressor while the EQ Boost unit is mounted between the engine and transmission. The electric compressor offers high charge pressure without any delay when moving off with the help of the EQ Boost unit, enabling the 3.0-liter straight six engine to perform essentially without lag.
The main goal was to reduce fuel consumption and emissions but still offer the performance and dynamics of a true AMG. The new CLS 53 claims a 0-62mph (100km/h) in 4.5 seconds and a top speed up to 167mph (270km/h) while returning a combined 8.5lt/100km (27.6mpg).
The driver gets to choose between five different driving modes ("Eco", "Comfort", "Sport", "Sport+" and "Individual"). The chassis has been upgraded with a multi-chamber air suspension, special steering knuckles and load-bearing joints and more negative camber on both axles.
Mercedes AMG will debut the new 53-Series models with a special Edition 1 version of the CLS 53 4Matic+ that features exclusive details, including a special interior with details finished in a fine copper color, black nappa leather with contrasting copper stitching, ambient lighting and more.
