Every experience we've had with Mercedes-Benz's new eighth-generation E-Class has been a positive one. From the near-stately luxury of the E350 and E550 sedans to the sporty thrills of the E-Coupe to the "ineffable joy"of the E-Cabrio, we've been big fans. Except... we all seem to end our reviews saying something like this, "While there is no doubt that the [whichever E-Class] is a first rate automobile, we can't help but wonder what the AMG version would be like." Well friends, let me tell you.
It's like driving veal. No, the E63 AMG is smoother than that. It's like driving veal fat. Citroëns wish they had rides as glassy. Potholes, ruts, expansion joints (i.e. Interstate 5 near Downtown Los Angeles), it really doesn't matter what the road surface is like. The E63 wafts you over it in serene comfort. And should you (somehow) become uncomfortable, just switch on the massaging seat. The max setting is stellar. "Wait a second," you say, this is an AMG product. It's not supposed to be all soft and cushy. Well, I'm kind of pulling a fast one, because I'm talking about driving the E63 with all of the adjustable stuff turned off. This is also known as "Comfort" mode, and truer words have rarely been printed in an owner's manual.
Of course, situated just in front of the gear selector is the AMG Drive Unit button that firms up the suspension in one of two ways. Push once for "Sport" and once again for "Sport Plus." Unlike the majority of cars fitted with such functionality, this button makes a world of difference. With Sport Plus engaged (who has time for regular old Sport?), moving at 110 mph with four grown men inside is like puttering about in traffic in any other car. Talk about an Autobaun cruiser, talk about a gentleman-thug. There's just no drama. Blame it on the E63's curious suspension set up.
There's an age-old problem that goes something like this: The weight on a car's front end is fairly static, specifically a front-engine, rear-wheel-drive sedan. However, the weight pressing down on the rear axle fluctuates. With four adults and a week's worth of luggage, we could be talking a quarter of a ton – or more. Most trucks have a perfect solution for this problem: Leaf springs. Of course, Mercedes-Benz would rather re-buy Chrysler than go down that path. Multi-link rear-ends with gas-shock dampers (like you'll find on most performance sedans, including the lesser E-Classers) can't adjust to the added and arbitrary weight. They require additional rear-spring stiffness to keep the car semi-level and this hurts ride quality. AMG's answer: Air suspension, but only in the rear.
