Mercedes-Benz has released a trio of electrified AMGs with the 53 models of the CLS, E Coupe and Convertible, and their claim to fame is their EQ Boost powertrains that supposedly deliver “zero lag” like an electric car.
The main story of these 53 models are their powertrain, which is a 3.0 liter inline-6 twin turbocharged to 435 hp and 520 Nm of torque, paired to an EQ Boost starter-alternator the can provide an additional 21 hp and 250 Nm of torque in short bursts. This has been achieved through the fitment of the inline-6 engine with a regular turbo and one electric auxiliary compressor, while the EQ Boost unit is mounted between the engine and transmission. The electric compressor offers high charge pressure with zero delay through the help of the EQ Boost unit, which is the reason why Mercedes claims this car has zero lag.
The EQ Boost starter-alternator also feeds these cars’ 48-volt electrical system. A 9-speed AMG Speedshift TCT 9G automatic transmission sends power to a 4MATIC+ all wheel drive system. With the tandem of the EQ Boost system and inline-6 twin turbo engine, the 53 models can sprint from 0-100 kph in 4.5 seconds, all the way to a top speed of 270 kph, while having an average fuel consumption of 12 km/l, or so they claim.
Elsewhere, there’s a few subtle changes to differentiate it over their standard counterparts but without going as aggressive as AMG’s 63 models. An Edition 1 version will be available to the CLS 53 4MATIC+, which features a special interior through the fitment of fine copper trimmings, black nappa leather with contrasting copper stitching, ambient lighting, and the likes.
