Mercedes-Benz has announced the introduction of the E300 BlueTEC Hybrid, available in both saloon and estate form, as well as the E400 Hybrid. Both vehicles will make their official debut at the upcoming NAIAS in Detroit in January.

The E300 BlueTEC Hybrid is powered by a four-cylinder diesel offering 204 hp and 500 Nm, working in tandem with an electric motor that produces 20 kW and 250 Nm – Merc says that the vehicle is the most economical luxury-class vehicle in the world.

The company adds that there’s no compromise in space, safety and comfort brought about by utilisation of the intelligent modular hybrid concept – no changes to the body of the base vehicle were necessary.

The car is part of the intelligent downsizing strategy of Mercedes-Benz – the E300 BlueTEC Hybrid is positioned at the same level as the E300 CDI, but offers fuel savings of around 15% compared with the E250 CDI, even in actual road traffic conditions.

Meanwhile, the V6 petrol unit in the E400 Hybrid cranks out 306 hp and 370 Nm, and the mill is also supplemented by the same electric motor’s 20 kW and 250 Nm.

The E300 BlueTEC Hybrid is initially planned to be launched on the European market, while the E400 Hybrid will be made available on the American market first, followed by other countries such as Japan and China later. Right-hand drive variants are scheduled.
