German carmaker Mercedes-Benz has unveiled the E-Class range topping performance models in the form of the ballistic E 63 AMG and the outrageously quick E 63 S AMG.
The new E 63 AMG lineup will make its public debut later this year in November in the 'City Of Angels' at the 2016 Los Angeles Motor Show.
Powering both the E 63 and E 63 S AMG is a revised version of AMG's 4.0-litre V8 engine which has been fitted with a pair of new twin-scroll turbochargers.
The new engine which was first seen on the AMG GT sports car, replaces the larger 5.5-litre twin turbo V8 from the last E 63 AMG.
In the E 63 AMG, the engine produces 563bhp and 750Nm. Underneath the hood of the E 63 S AMG, the turbocharged engine is mounted on dynamic mounts and cranks out 604bhp and 850Nm of torque which makes the E 63 S AMG the most powerful E-Class of all time.
The E 63 AMG will sprint from 0 - 100 km/h in just 3.5 seconds while the more powerful E 63 S does the same sprint in 3.4 seconds. That 3.4 second time makes the E 63 AMG S the fastest accelerating AMG ever produced.
The top speed of both cars is limited to 250km/h, which can be lifted to 299km/h if owners specify the AMG Driver's package.
The engine in both variants of the E 63 is paired with a Merc's 9-speed dual clutch automatic gearbox which sends the power and and torque to all four wheels through Merc's 4-Matic+ four-wheel drive system.
However, don't let the four-wheel drive system fool you into thinking the AMG Lunacy is gone, as Merc's performance arm has ensured the E 63 retains its reputation of being a drifter's dream machine with the help of what they call drift mode.
Drift mode, which can be activated by pulling both paddles, sends all the power and torque to the rear wheels alone to ensure that drivers can still have some smoky burnout fun.
There are four driving modes, Comfort, Sport, Sport Plus and Individual.
In comfort mode, the new engine is as frugal as possible and decouples itself from the gearbox when the driver lifts off the accelerator pedal from 59.5km/h to 161km/h.
Four cylinders of the V8 engine are also deactivated between 1,000 and 3,250rpm to save fuel.
To ensure that the new AMG tuned E-Class can stop properly, Mercedes has fitted the E 63 AMG with 360mm steel discs with six pot calipers up front. The front discs are even larger on the S variant at 390mm.
The rear brakes on both cars are 360mm discs with single pot calipers.
Also available as an option are carbon ceramic discs which measure 402mm up front and 360mm at the rear.
Design wise, the new E 63 AMG and E 63 S AMG feature a brand new grille with the Mercedes 3-pointed star front and centre.
The grille features multiples vertical slats along with twin chromed out horizontal slats that link up with the Merc badge. The front bumper also looks more aggressive than the one on the normal E-Class.
On the sides, the wheel arches are extend out 17mm more than on the standard E-Class and they house 20-inch alloy wheels that are shod with 265/35 R20 front and 295/30 R20 rear tyres.
At the rear, the new AMG powered E 63 and E 63 S feature a redesigned bumper with four tailpipes sticking out along with small bootlid mounted spoiler.
Inside, the cars feature loads of carbon-fibre trim along with leather and alcantara. The instrument cluster has made way for a large digital display which is flanked by the touchscreen display hosting the infotainment system.
The new E 63 and E 63 S AMG will go on sale in Europe in January 2017 with deliveries starting in June the same year.
The new E 63 and E 63 S AMG will go up against the BMW M5 and the Audi RS6 when it finally hits the streets next year.
