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 CoupeÃ 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.
