High-Rev Hero
Everyone that's driven the car seems to really like it. Haven't read any of the 'boring to drive' or the 'can't corner' comments.
^Yep..AMG did their magic.![]()
Wow wait a minute. Do you say a standard ML can't corner?![]()
AMG's twin-turbo V-8 has us convinced that those initials stand for "AlMighty God!"
While all vehicles—AMGs included—have their compromises and shortcomings, Mercedes-Benz’s performance arm is on a basic philosophical plane that we very much admire: If it exists, cram more motor into it. Small, medium, and large sedans? (Plus another medium with a different roofline?) Check. Coupes? Check. Roadsters? Check. SUVs? Check. Thirty-three-year-old military vehicle? Check. Crazy-ass German luxury minivan? Check. The German powerhouse hit its stride over the past five years, stuffing a 6.2-liter V-8 of its own creation into a wider variety of Mercedes-Benzes than have ever worn the badge of Aufrecht, Melcher, and Grossaspach at one time. Then, in the name of efficiency, the brand ditched that motor in favor of a 5.5-liter twin-turbo V-8. In doing so, AMG dropped not one horsepower and stumbled upon 185 more lb-ft of torque than its suddenly sleepy-looking 6.2 had in its strongest form. (We will for now ignore the new engine’s acoustic deficiency.)

Currently, the M157 twin-turbo is available in seven different Benzes. Its output varies among them; the ML tested here with the optional Performance package makes 550 hp and has its twist capped at 560 lb-ft. The latter, need we remind you, is still more than any other SUV on the market. That prodigious output thrust the 5285-pound ML seen here to 60 mph in 4.2 seconds, to 100 in 9.8, and through the quarter-mile in 12.6 at 113 mph. Given enough space, it’ll stretch its legs all the way to a governor-limited 175. (Because you and that small herd of goats you’re hauling would otherwise want to go faster.)
Faster Than We Can Count
While the turbos muffle some of the sound of small explosions happening as many as 480 times a second, the ML was never the most vocal AMG. Its engine is, however, a very smooth device for combusting gasoline at such a furious rate. With max torque available from 2000 rpm to 5000 and horsepower peaking at 5750, the ML driver just experiences one long pull from stationary to “Well, officer, I honestly had no idea I was going that fast. The baby (goat) didn’t even wake up!” It does execute fluttering burps on upshifts and some mild spitting on downshifts and overrun, though, so that those who wish they’d instead bought an E63 AMG wagon don’t trade in their M-classes immediately.

In spite of their similar outputs, performance, and cost, these two two-box AMG “63” vehicles are quite different. Where the E63 wagon engages its driver, the ML—redesigned for this year—takes more of an “are we there yet?” approach to its limits. Unlike a haggard parent repeating, “Yes, yes, now please stop cattle-prodding your sister,” though, the ML pilot hasn’t a clue how close he is to the limit until he’s there. As it nears, communication dies down significantly. The steering never says much, there’s little roll, and the tires are quiet right up until they’re yowling in understeer. Well, maybe there’s a little more vocal warm-up, but coddled inside the serene interior, you’ll never know. The ML63 isolates the driver from the sensation of speed in a way that is unique to Mercedes-Benzes and perhaps perfected in this particular one.
Money Buys AMGs. Ergo, Regarding Happiness . . .
Still, is all that a fair return on an investment of more than $100,000? While the base ML starts at $49,865, the ML63 demands a minimum contribution of $95,865. With another $6550 for the AMG Performance package (without, you only get an embarrassing 518 hp and 516 lb-ft, and you won’t have a carbon-fiber engine cover), plus $1600 for piano-black trim, $1970 for a rear entertainment system, and $1610 for 21-inch wheels (that surprisingly do not destroy the ride)—and a few hundred apiece for the Diamond White paint and heated rear seats—the example tested here totaled $109,010. It seems a little silly, given that that amount would also buy you both a base Porsche Boxster and an ML350, but we’d be willing to bet that many AMG buyers already have a Boxster (or Corvette or Lotus or M3 or . . . ) sitting next to the space reserved for the new ML. Why not make that ML an AMG? We can’t fault buyers there.

Verdict ***
The Mercedes ML63 AMG is an impressive example of a performance SUV, which matches the performance and handling of a car that's much smaller and lighter. But, it’s missing the involvement that drivers will get from a Porsche Cayenne and that’s a crucial ingredient for creating a super-SUV. If you really are after an M-Class, the sensible money would go on a ML350 CDI, which is not only almost as quick in-gear but will be far cheaper to buy and run, too.
