Mercedes is gearing up to introduce the next-generation E-Class at the North American International Auto Show and new details are starting to emerge about the upcoming model.

According to Car & Driver, the model will usher in an all-new engine family.  The first application is expected to be a four-cylinder diesel that produces approximately 180 bhp (134 kW).  The engine family will eventually expand and include four-cylinder petrol engines as well as inline-six cylinder petrol and diesel engines.

The E-Class is also rumored to adopt a new 48-volt mild-hybrid system.  Details are light at the moment but the magazine says the system will feature a starter-generator that is integrated into the car's transmission.  These types of systems offer modest fuel economy gains thanks to an engine start/stop function but it also should be able to provide a temporary boost in performance.

We're still a couple of weeks away from seeing the car in the flesh but previous spy photos have shown the model will have a familiar design that borrows a number of styling cues from the C- and S-Class.  The exterior styling won't be revolutionary but the cabin will be significantly more upscale as it adopts a digital instrument cluster, a larger infotainment system and higher-end materials.
