A price tag of $195,000 will place it $20,000 below the current entry model – the six-cylinder turbo diesel S350 Bluetec.
The Mercedes-Benz S300 Bluetec Hybrid teams a 150kW/500Nm 2.1-litre four-cylinder turbo diesel with an electric motor with outputs of 20kW and 250Nm.
It’s a slow S-Class in relation to other models with a 0-100km/h claim of 7.6 seconds, though its fuel consumption leads the way at 4.5 litres per 100km. CO2 emissions are rated at 118g/km.
Pure electric driving is limited on the S300 – the electric motor is mainly there to assist acceleration.
S300 will expand the S-Class line-up to six, with short- and long-wheelbase versions of the S350 and V8-powered S500 topped by the $385,000 S63 AMG.
The Mercedes-Benz S-Class Coupe, which makes its public debut at this week’s 2014 Geneva motor show, is expected to arrive by the end of the year.
