The sole diesel version of the Mercedes-Benz CLA-Class - the CLA200 CDI - has been updated with a new engine.

The CLA200 CDI that has been sold up until now was powered by a 1.8-litre four-cylinder turbo diesel with 100kW of power and 300Nm, but the CLA-Class will now move to a larger 2.2-litre four-cylinder turbo diesel while retaining the same power outputs.

The new 2.2-litre engine is the same unit seen in the GLA-Class SUV, and despite offering the same power and torque, the fuel use drops from 4.7 litres per 100km (current Australian claim) to 4.0L/100km (EU test cycle). The fuel savings include an optimised belt drive, revised vacuum pump, revised assembly clearances and a low-friction ring package, and updated cylinder heads. The seven-speed dual-clutch remains a standard fit item.

Mercedes-Benz Australia told CarAdvice the new engine will be fitted to all CLA200 CDI models ordered from now, with production commencing in September. No change in pricing is expected, with the CLA200 CDI staying put at $50,400.

The 2.2-litre engine will also be added to the A-Class before the end of this year, replacing the 1.8-litre in the A200 CDI.
