Every CLS comes with a pair of 10.25-inch screens running Mercedes’ MBUX operating system; one is the central touchscreen, the other is a digital dial cluster. A larger, 12.3-inch twin-screen setup is available as an option. 

Engines and performance

The standard versions of the CLS are available with a choice of two diesel engines, with the AMG 53 boasting a six-cylinder petrol engine. Every model features Mercedes’ 4MATIC four-wheel drive and a nine-speed automatic gearbox. 

The base CLS 300 d is powered by a 2.0-litre four-cylinder diesel, producing 261bhp. It has mild-hybrid electrical assistance with a 48-volt integrated starter-generator that recovers energy when coasting. This energy is stored in a battery and is then used to give the engine a temporary 20bhp boost under hard acceleration. 

Performance is brisk, with the CLS 300 d managing 0-62mph in 6.4 seconds and a limited top speed of 155mph. It’s the most efficient model in the range too, with claimed fuel economy of up to 48.7mpg and CO2 emissions starting at 144g/km.

The flagship CLS AMG 53 combines a 3.0-litre six-cylinder petrol engine and mild-hybrid technology to produce 423bhp. It’s the fastest CLS in the range, going from 0-62mph in 4.5 seconds. In factory spec, it's top speed is limited to 155mph but buyers can opt for the optional AMG Driver Package, which increases the limiter to 168mph.
