Mercedes-AMG E43 4Matic revealed at New York motor show

The gearbox has been given AMG-specific software mapping, providing it with a claimed reduction in shift time over the standard unit used by other new E-Class models, as well as the ability to hold gears at the redline rather than shifting up. It also provides a multiple downshifting and a double declutching function in Sport and Sport Plus modes – two of a total of six modes that also include Eco, Comfort, Individual and Manual.

Official performance claims put the E43 4Matic’s 0-62mph time at 4.6sec – the same figure Audi quotes for the S6. As with its closest four-door rival, top speed is limited to 155mph. The official combined cycle fuel consumption is 34.0mpg and average CO2 emissions are 189g/km.

The E43 4Matic is underpinned by a re-tuned version of the new E-Class’s Air Body Control suspension. It uses multi-chamber air springs that provide adaptive damping properties in three modes: Comfort, Sport and Sport Plus. Among the changes to the standard geometry are new steering knuckles and load bearing joints for the four-link front suspension, greater negative camber on both the front and rear wheels and stiffer spring and damper rates.

The variable ratio electro-mechanical steering system has also been retuned and, in combination with the adaptive damping, it offers the choice of two modes: Comfort and Sport.  

Reining in the added performance potential brought on by the new engine is an upgraded brake package featuring 360mm steel discs with four-pot calipers up front and similar dimensioned 360mm steel discs with single pot calipers at the rear.

An AMG styling package helps to distinguish the E43 4Matic from other new E-Class models. Included in the visual makeover is a more heavily structured front bumper with larger air ducts, a diamond themed grille insert, wider sills, a revised rear bumper with integrated diffuser element and quad trapezoidal shaped tail pipes and standard 19-inch wheels.

Inside, the initial range topping E-Class model has sports seats, a flat bottom multi-function steering wheel and AMG-specific instruments.

Together with the saloon variant of the E43, AMG also plans an estate of its latest V6-powered model. Pricing is yet to be announced, though officials suggest the new four-door will pitch in above £50,000.
