Just a day after BMW had unveiled the updated M5 Competition, Mercedes-AMG had quickly responded to Bavaria's challenge. With the E-Class being recently facelifted, it was only a matter of time before the E63 AMG would be revealed.
But while BMW had beat them to the punch, the AMG has brought more torque to the table. Its 4.0-liter BiTurbo V8 doles out a whopping 850 Nm of torque. To put that into perspective, that's 100 Nm more than the M5 Competition. Horsepower is rated at 612 PS, which is less than the M5 Competition (617 PS), but that torque advantage comes into play in acceleration.
Despite having less horsepower than the BMW, the E63 S can do the 0 to 100 km/h sprint in 3.4 seconds. Top speed on the other hand is rated (and limited to) 300 km/h for the E63 S. Helping it go that fast is a nine-speed automatic transmission, which has been beefed up and tuned by AMG to withstand all that torque.
But if you find over 600 PS in a luxury sedan overkill, there's also a 'base' E63 AMG. That one makes 571 PS and 750 Nm of torque. It uses the same nine-speed automatic transmission unit from the E63 S, and its top speed is restricted to 250 km/h. Both the E63 and E63 S are all-wheel drive with individual drive modes. However, the E63 S benefits from a rear-wheel-drive-only mode which AMG calls Drift Mode.
The Mercedes-AMG E63 and E63 S are available in both sedan and wagon body styles. The wagon is one-tenth slower than the sedan when it comes to acceleration. Top speed is limited to 250 km/h for the standard E63, while the E63 S is limited to 290 km/h.
To keep it planted on the road, AMG Ride Control + and an Adaptive Damping System. Mercedes-AMG also re-tuned the rear axle to enhance handling, plus it has an electronic locking rear differential. Then there's the suspension itself and it rides on air springs. AMG says that it gives this super sedan a comfortable ride at the press of a button, but can also be made stiffer if Race mode is engaged. AMG went as far as saying that the difference between the modes is “clearly perceptible”.
Stopping power is then provided by 360 mm slatted vented discs on all corners. Go for the S version and those go up by 390 mm at the front. But if it's fade-resistant brakes you want, there's also the AMG Carbon Ceramic brake package, which brings the front brakes up to a massive 402 mm.
AMG models have been sold in the country for quite some time now, so we expect this E63 or E63 S sitting in showrooms eventually. But before we get to these high-performance sedans, we'll be waiting for the heavily updated E-Class to land here first.
