Hot new flagships for the CLS and E-Class Cabriolet and Coupé pack mild-hybrid tech

Mercedes-AMG has broadened its line-up with the addition of three new mild-hybrid models – the CLS53, E53 Coupeà and E53 Cabriolet.

Unveiled at the Detroit motor show, the trio of new AMG models will go on UK sale in autumn at prices expected to start at around £60,000 and extend to more than £70,000.

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 CLS53, E53 Coupeà and E53 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 facelifted S500, develops 429bhp at 6100rpm and 383lb ft of torque from 1800rpm to 5800rpm.

An integrated starter/ alternator helps boost performance, delivering an additional 22bhp and 184lb ft 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 E43 saloon, among other AMG models, delivers 395bhp and the same 383lb ft of torque.

Can the Mercedes-AMG CLS 63 S provide sensationally entertaining, as well as civilised, executive transport?

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 1895kg E53 CoupeÃ, the new driveline provides 0-62mph acceleration in a claimed 4.4sec. The 1980kg E53 Cabriolet and 1905kg CLS53 are both claimed to have a 0-62mph time of 5.3sec. All three new AMG models run to a governed 155mph top speed.

For reference, the existing E43 saloon has a claimed 0-62mph time of 4.7sec and the same 155mph 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 CoupeÃ, E-Class Cabriolet and new CLS ranges.

Differentiating the CLS53, E53 Coupeà and E53 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 19in wheels, with 20in rims available as an option.

Inside, there is a new AMG performance steering wheel, among other unique interior styling touches.

I am thoroughly unconvinced

I am thoroughly unconvinced that a hybrid system has ever made a car more enjoyable drive.

I would be fascinated to read a back to back review of something like a P1 in standard and hybrid removed states.

I am also terrified by what these things will be like to own and maintain when they are 5+ years old, warranties have expired, and manufacturers have lost interest in them.

Very heavy and slow, RS5 with

Very heavy and slow, RS5 with its 450HP runs 3.6 to 60,admittedly smaller and much lighter [1515kg] RS3 does 3.5.Very disappointing, I was expecting much better, as I love the lines of them and the room and pillarlessness of the coupe.

62 mph in 5.3 seconds!? 4.3

62 mph in 5.3 seconds!? 4.3 seconds more likely.
