The trio of new AMG models were unveiled at the Detroit motor show and are expected to go on sale, soon.
AMG chairman Tobias Moers said: “With the new 53-series models, we are extending our portfolio in the first step towards a hybridised future.”
Power for the CLS 53, E 53 Coupé and E 53 Cabriolet hails from a new 3.0-litre six-cylinder engine featuring twin turbocharging by means of an electric compressor and an exhaust gas turbocharger.
The in-line unit, which already powers the S 500 facelift, develops 435hp at 6,100rpm and 519Nm of torque from 1,800rpm to 5,800rpm. An integrated starter/ alternator helps boost performance, delivering an additional 22hp and 249Nm of torque for brief periods while also providing electric energy for a 48V electric system. By comparison, the more conventional twin-turbo 3.0-litre V6 used by the E 43 sedan, among other AMG models, delivers 400hp and the same 519Nm of torque.
The new mild-hybrid engine, which is planned for use in other AMG models over time, is mated to a standard nine-speed AMG Speedshift automatic gearbox and fully variable 4Matic+ four-wheel drive system.
In the 1,895kg E 53 Coupé, the new driveline provides 0-100kph acceleration in a claimed 4.4sec. The 1,980kg E 53 Cabriolet and 1,905kg CLS 53 are both claimed to have a 0-100kph time of 5.3sec. All three new AMG models run to a governed 250kph top speed. For reference, the existing E43 sedan has a claimed 0-100kph time of 4.7sec and the same 250kph top speed.
The three new 53-series AMG models are set to crown their individual line-ups, with Mercedes-AMG confirming that there are no plans for full-blown 63-series models in the E-class Coupé, E-class Cabriolet and new CLS ranges.
Differentiating the CLS 53, E 53 Coupé and E 53 Cabriolet from their standard siblings is a series of traditional AMG design elements, including a twin-blade grille, uniquely styled bumpers, wider sills and signature AMG tailpipes. The new models come as standard on 19-inch wheels, with 20-inch rims available as an option.
Inside, there is a new AMG performance steering wheel, among other unique interior styling touches.
