In one fell swoop, Mercedes has unveiled the entire lineup of facelifted E-Class vehicles at the North American International Auto Show.

Extensively revised, the updated models have a new front fascia with a rounded grille, restyled headlights and new air intakes. Out back the changes are less noticeable but include a modified bumper, new tail lights and additional chrome trim.

The cabin sees modest updates including a new center console, improved seats and an updated color palette. 

Under the hood, a variety of different engines are available. The mainstream models offer six petrols with outputs ranging from 184 HP (135 kW) to 408 HP (300 kW). There are also six diesel options which churn out 136 HP (100 kW) to 265 HP (195 kW).

If you're looking for something with a little more oomph, the E63 AMG has a twin-turbo 5.5-liter V8 engine that develops 557 HP (410 kW) and 720 Nm (531 lb-ft) of torque. There's even a new E63 AMG S that boasts 585 HP (430 kW) and 800 Nm (590 lb-ft) of torque. This enables the latter model to accelerate from 0-100 km/h in as a little as 3.6 seconds. The E63 AMG can also be ordered with a new all-wheel drive system which is sure to cause a little concern in Ingolstadt.

The 2014 Mercedes E-Class lineup will be rolled out in the coming months, so expect to see them at dealerships shortly.
