The new E 63 will continue in both Sedan and Estate bodystyles, with power and performance upgrades joined by a new 4Matic all-wheel drivetrain option - the latter available only in overseas models.
The 2014 model wears unique new styling at both ends, along with the E-Class models’ new singular headlights, updated tail-lights, re-styled flanks and S-Class-previewing technologies.
The 2013 E 63 continues in two performance levels, with the previous Performance Package upgrade now replaced by the ‘S-Model’ moniker.
S-Models can be distinguished by their matte 19-inch wheels and red brake calipers, and gloss black and silver chrome body detailing.
All-wheel drive 4Matic models are also fitted with 19 inch wheels, but are finished in gloss titanium grey as per the standard E 63’s 18s.
The E 63’s current 5.5 litre twin turbo V8 engine (introduced in 2011) remains for the 2013 update, but features boosted output in both guises.
Power and torque increases from 386kW/700Nm to 410kW/720Nm for the basic E 63 models, while the S-Model benefits from increased boost pressure (from 0.9 to 1.0 bar) to lift power beyond the previous Performance Package’s 410kW to 430kW.
The S-Model’s torque figure is unchanged at 800Nm, and continues to include a locking rear differential.
In left hand drive markets, the 2013 E 63 will be available with 4Matic AWD for the first time, with the system’s 33:67 front/rear torque split and torque-vectoring capability tailored specifically toward driving dynamics.
The 4Matic system adds 70kg above rear-wheel drive models, but the system’s traction advantage drops the standard E 63 sedan’s acceleration from a claimed 4.2 seconds 0-100km/h to 3.7 seconds.
Quickest of the range is the E 63 S-Model 4Matic Sedan, producing a Ferrari Enzo-matching 3.6 second figure.
Claimed figures for Estate E 63 4Matic variants are just 0.1 second behind for 4Matic, and Mercedes is yet to quote figures for rear-wheel drive E 63 wagons.
The seven-speed AMG Speedshift automatic transmission remains the sole transmission choice, integrating "compromise-free" with the 4Matic system.
All E 63 models continue with AMG Ride Control adaptive suspension system, but S-Model and 4Matic equipped use new aluminium front suspension components to help eliminate traditional AWD understeer and offer more performance-focused suspension behaviour.
Braking continues with six-piston front, and four-piston rear units on the entry E 63s, with 360mm discs at all corners.
However, the orange coloured ceramic-composite 402mm units are now exclusively optional on the S-Model.
The 2013 E 63 AMG shares the many spec upgrades of the regular E-Class models, including the availability of “intelligent drive” driver assistance features, COMAND Online system, and full-LED headlights.
AMG-specific features include a unique version of the new analogue clock, stainless steel pedals, metallic trim details and assorted AMG branding to the standard black leather trim.
The S-Model is distinguished by contrasting grey coloured trim stitching, silver seatbelts, while the steering wheel gains a flat top and bottom and alcantara trim.
An S-AMG logo appears in the centre of the 320km/h speedo, and the standard AMG sill trims gain LED backlighting.
Options include a 1200W Bang & Olufsen audio system, along with carbon fibre or piano black trim options, plus the full range of designo individualisation choices.
Exterior options include two different grades of carbon fibre trim adornment, extensive gloss black exterior detailing, five spoke AMG wheels, and a carbon fibre engine cover.
Following the 2013 E 63 AMG models’ Detroit public debut next week, the first rear-wheel drive models will be available internationally from April, while the 4Matic and S-Models will follow in June.
Australian E 63 specs and pricing are yet to be finalised, but Mercedes-Benz Australia has confirmed that the 4Matic models will not be produced in right-hand-drive.
This means that Australian E 63s will remain rear wheel drive-only and will arrive on our shores with the refreshed E Class Coupe and Convertible models in September.
