MERCEDES-AMG has launched its long-awaited 53-series “AMG-lite” badge, introducing three new models featuring a 320kW 3.0-litre twin-turbo in-line six-cylinder engine, and an electric compressor and motor.
The fastback-styled CLS saloon, and the E-Class Coupe and Cabriolet will be the first models to wear the new badge. Combined with the 16kW/250Nm electric starter motor/altenator fitted between the engine and the transmission and powered via a 48-volt system, and mated to a nine-speed automatic transmission, the combined power unit is good for a 4.4-second 0-100km/h sprint in the E53 Coupe, with drive in all three cars sent to all four wheels.
“With the new 53-series models we are extending our portfolio in a first step towards a hybridised future with a leading-edge combination of sporty design, performance and efficiency,” Mercedes-AMG chairman Tobias Moers said.
“The basis for this is a contemporary drive configuration in the form of a six-cylinder in-line engine with electric auxiliary compressor, EQ Boost starter-alternator and 48-volt on-board electrical system,” Moers said.
The electric compressor allows the 53-series to provide the in-line six with a big dose of torque low down in the rev range – right where turbo lag would have bogged it down. “Supported by the EQ Boost starter-alternator when moving off, the electric auxiliary compressor builds up a high charge pressure without any delay, for a faster increase in torque for acceleration until the large exhaust gas turbocharger is deployed,” the car maker said.
The 53-series cars also introduce a new AMG Performance steering wheel to the Mercedes-AMG line-up. The wheel wheel is wrapped in nappa leather, with options available including wood inserts in piano lacquer or Dinamica microfibre in the grip area.
