Sharing the same 66kW/220Nm 1.5-litre four-cylinder turbo-diesel engine and six-speed manual transmission, the A160 and B160 CDI models will hit 100km/h in 13.8 and 14 seconds respectively, before both reach a top speed of 180km/h.
While in the A-Class the engine delivers efficiency figures of 3.8 litres per 100km and 98 grams of CO2
per kilometre, in the B-Class these increase to 4.1L/100km and 108g/km.
The B220 4MATIC – the first B-Class to feature all-wheel drive – combines a 135kW/300Nm turbocharged 2.0-litre petrol engine with a seven-speed dual-clutch automatic transmission to accelerate from 0-100km/h in a claimed 7.5 seconds. Fuel and CO2
figures of 6.5L/100km and 151g/km are also claimed.
Replacing the B180 CDI’s previous 80kW/250Nm 1.8-litre four-cylinder diesel engine is a 1.5-litre unit. Despite the smaller capacity, power output remains unchanged, torque is increased by 10Nm and consumption has been reduced from 4.4 to 4.1L/100km.
Delivering even better economy in the B180 CDI BlueEfficiency Edition, the same 1.5-litre engine delivers a claimed 3.8L/100km. The updated model has had its aerodynamics, suspension height and six-speed manual transmission all revised to reduce fuel consumption by seven per cent over the previous model.
Though the new and updated models are due to arrive in German dealerships in September, alongside the CLA250 4MATIC, CLA45 AMG and CLA45 AMG Edition 1, Mercedes-Benz Australia is remaining tight-lipped about any planned expansion of the local A- and B-Class ranges.
