Mercedes is gearing up to introduce two new E-Class hybrids.

First up, the E300 BlueTec Hybrid will use a 2.1-liter four-cylinder diesel engine with 201 hp (150 kW / 204 PS) and 369 lb-ft (500 Nm) of torque. It will be backed up by an electric motor that develops 27 hp (20 kW / 27 PS) and 184 lb-ft (249 Nm) of torque. Thanks to this setup, the car will reportedly accelerate from 0-100 km/h in 7.5 seconds and hit a top speed of 241 km/h (150 mph).

In terms of efficiency, the model is expected to return a combined 67.3 mpg UK (56 mpg US / 4.2 L/100km) with CO2 emissions of 109 g/km. Additionally, the 0.8 kWh lithium-ion battery should enable the vehicle to travel approximately one mile (1.6 km) on electricity alone.

There's also word of a US-only E400 Hybrid which will use the aforementioned electric motor and a 3.5-liter V6 petrol engine. It is slated to return 32.4 mpg US (38.9 mpg UK / 7.2 L/100km).

Both models are expected to be unveiled at the North American International Auto Show, so stay tuned for full details.
