The wholly turbocharged global powertrain line-up includes six petrol variants and five diesels, ranging in size from 1.6 to 3.0 litres.
The most efficient model is the C350 Plug-In Hybrid, which will join the line-up in 2015 after the launch of the initial variants in the coming months. Teaming a 155kW/350Nm 2.0-litre four-cylinder petrol engine with a 50kW electric motor, Mercedes-Benz claims the plug-in C-Class uses just 3.0 litres per 100km on the combined cycle, making it the most efficient variant in the car’s history, and almost twice as economical as BMW’s non-plug-in ActiveHybrid 3 (5.9L/100km).
Joining the petrol-powered plug-in is a diesel-electric model, the C300 Hybrid, which teams a 150kW/500Nm 2.2-litre four-cylinder diesel engine with a 20kW electric motor. Mercedes claims consumption of 3.8L/100km, as well as average CO
emissions less than 100 grams per kilometre.
The new C300 trades the 3.5-litre V6 of the old model for the top tune of the new model’s turbocharged 2.0-litre four-cylinder petrol engine. Power falls 10kW to 175kW, though torque climbs 30Nm to 370Nm, and claimed fuel consumption drops 20 per cent to 6.3L/100km.
Headlining the petrol line-up is the all-new C400, which inherits the twin-turbocharged 3.0-litre V6 from the larger E400. Power and torque are unchanged from the E-Class at 245kW and 480Nm – easily accounting for the 225kW/400Nm of the 3.0-litre turbo inline-six-powered BMW 335i.
Mercedes-Benz’s data sheet says the C400 will be available exclusively with the brand’s 4MATIC all-wheel-drive system, though unlike the previous-gen car, AWD versions of the new C-Class will be available in right-hand drive, leaving the door open for the C400 to join the Australian line-up.
Not mentioned in the Mercedes-Benz C-Class engine line-up is the new C63 AMG performance model. Due in 2015, the C63 AMG will be powered by an all-new twin-turbocharged 4.0-litre V8, with outputs reportedly set to peak at about 360kW and 700Nm.
Details of the entry- and mid-level engines were announced at the unveiling of the new C-Class in December.
The fourth-generation Mercedes-Benz C-Class will go on sale in Australia in mid 2014. Full details of the new premium mid-sized sedan and wagon range will be released closer to its local launch.
