2021 Mercedes-AMG E63 S Wagon vs. Audi RS6 Avant Comparison Test Review


Mercedes-Benz E-Class Full Overview

Working example: The Audi RS6 begins life at $110,045, and the E63 S Wagon begins at $113,500. Emphasis on begins, as by the point just a few possibility packing containers are ticked the full kitty for the Mercedes is $129,120. To not be outdone, the Audi’s value swelled to $131,645 as examined. Not low-cost, not even kinda low-cost, although for some, effectively well worth the scratch. We’ll get to why that is so in a second.

Again to the similarities, each high-performance haulers are wagon variants of their respective manufacturers’ brot und butter midsize sedans. The RS6 is underpinned by the (we suspect) fairly nice A6 Avant, whereas the AMG is a hot-rodded model of the (little doubt) wonderful E-Class Wagon. Why my uncertainty? For causes too cynical to breathe air into, neither Audi nor Mercedes-Benz deems the U.S. an applicable marketplace for their regular wagons. As an alternative, Individuals get the A6 Allroad and the E450 All-Terrain, ever so barely jacked-up wagons that cross some authorized/advertising definition of an SUV, although each of which fail to cross the SUV scent check. I’ve digressed, although not with out an appropriate serving of self-righteousness. Level is, each uber-wagons have unbelievable bones (particularly the AMG, because the 2021 E-Class simply won our 2021 Car of the Year award), and a stable skeleton is a good place to begin.

Then simply begin including energy—like numerous it. My largely knowledgeable opinion since 2015 is that the Dodge Hellcat’s stratospheric 707 horsepower and 650 lb-ft of torque so shattered energy norms (particularly now that the engine makes 717 hp) that we automobile fanatics as a neighborhood can now not suppose clearly. For example, as a result of Hellcat, you may hear that the RS6’s 4.0-liter, twin-turbo V-Eight produces 591 horsepower and 590 lb-ft of torque and suppose, “That is not that a lot.” I am a sufferer of this form of relativism, as effectively, however let me inform you, that is a wagon stuffed with energy. Bazinga! Naturally, inevitably, the AMG makes even extra energy from its personal hand-assembled, 4.0-liter, twin-turbo V-8: 603 horses together with 627 lb-ft of twisting power. Each wagons ship with AWD, although the E63 S has a Drift mode that turns off energy to the entrance axle, permitting the monster motor’s full output to hit solely the rear wheels. I am nonetheless smiling. The Audi has an eight-speed ZF automated transmission, whereas the AMG makes use of a high-output model of Mercedes’ nine-speed autobox.

The Audi is the bigger automobile, relying, in fact, on the way you outline the phrase “bigger.” The RS6 weighs extra, 4,862 kilos versus 4,658 kilos for the E63 S Wagon. Initially, sure, each schleppers are shockingly heavy. And why is the Audi over 200 kilos fatter? Automobiles basically are getting heavier as they change into ever extra laden with security, know-how, and, within the case of those two, biggish, turbocharged eight-cylinder engines that require loads of cooling energy, in addition to heavy all-wheel-drive {hardware}. Nonetheless, practically 2.5 tons? That is fairly absurd for supposed efficiency automobiles.

Again to defining bigger, the Mercedes-AMG has a fractionally longer wheelbase (by 0.Four inch) and is identical quantity longer general, although the Audi is wider and a skosh taller. The Mercedes has 5 additional cubic ft of cargo house within the again (35 to the Audi’s 30).

The Audi comes with a lot larger wheels and tires than the AMG, 22-inch Pirelli P Zeroes with a 285 part contact patch throughout versus the AMG’s 20-inch 265 entrance, 285 rear Michelin PS4s. The Audi’s brakes are large, particularly within the entrance: 17.3-inch carbon-ceramic rotors (14.6-inch within the again) that aren’t solely the biggest brakes fitted to any manufacturing automobile, however the identical rotors you will discover on different Volkswagen Group tremendous merchandise just like the Lamborghini Urus and Porsche Cayenne Turbo. That makes good sense as a result of the RS6 weighs simply 137 kilos lower than the Urus. The E63 S Wagon additionally comes with giant, carbon-ceramic rotors (15.8-inch entrance, 14.2-inch rear), although just like the aforementioned Hellcat horsepower dissonance, the AMG’s brakes positive do not sound as giant. They’re, nonetheless, rather more efficient. The Mercedes wagon can cease itself from 60 mph in 104 ft. The Audi requires 113 ft to do the identical. That is a substantial gulf, although round our figure-eight check observe, which options two lavatory braking zones, each wagons full the lap in 24.2 seconds.

What about straight-line efficiency? Glad you requested! Regardless of their lardiness, these two wagons are veritable cheetahs. The Audi hits 60 mph in 3.1 seconds, and the AMG wants simply 3.Zero seconds to do the identical. Loopy, I do know. Pull 200 kilos out of the Audi, and these two could be dead-butts even, I guess. The Mercedes’ half-pound-per-horsepower weight benefit actually reveals up within the quarter mile, the place it does the deed in 11.2 seconds at 124.Zero mph, whereas the nonetheless blisteringly fast RS6 wants 11.5 seconds at 120.2 mph. Apparently, the E63 S Wagon ties its sedan counterpart in each 0-60 and quarter-mile instances, although it’s 0.2 mph slower on the finish of 1,320 ft. The RS6 is actually a wagon model of the swoopy-roofed RS7, although we have not examined a 2021 mannequin but. For slightly perspective, the 760-horsepower Ford Shelby GT500 CFTP (Carbon Fiber Monitor Pack, aka the lighter model) runs the quarter mile in (a traction-limited) 11.Three seconds, although it traps at 131.6 mph. My level: These two station wagons are ridiculous each in idea and actuality. What a world.

So, which wins? By way of luxurious, journey high quality, and tech options, the 2 are practically similar. Mercedes’ MBUX infotainment system has extra depth to its performance, however Audi’s second-generation Digital Cockpit Plus is less complicated to make use of. So far as design goes, the RS6 is an absolute knockout. Top-of-the-line-looking wagons, effectively, ever. Not like the E63 S, the RS6 truly receives completely different physique panels—40mm wider fenders, particularly—although the entrance fenders are shared with the RS7. The Mercedes solely will get an AMG-specific grille. That stated, the long-roof AMG is a handsome automobile. It is simply that the Audi is up a shelf or two by way of visible desirability. It is the wagon that begins conversations at fuel stations.

Which wagon for me? AMG, palms down. Why? As a result of the E63 S drives a lot higher than the RS6. I hate to say it, not to mention sort it, however the Audi was a dynamic disappointment. From steering really feel, to brake response, to suspension sophistication, to physique management, to engine ferocity, the AMG was higher. By way of driving enjoyable, driver confidence, and automobile precision, this wasn’t a good battle. Working example: After I was looping these two plus the Porsche Panamera Turbo S Sport Turismo within the canyons above Los Angeles, the Porsche and the AMG may sustain with one another. If you happen to have been driving the Audi, after just a few turns you could not even see the opposite wagons.

The above being stated, how can we sq. the truth that the 2 had similar figure-eight instances? If I needed to choose the large purpose, I might say it is physique management. The Audi’s air suspension is solely inferior to the AMG’s comparable setup. While you’re driving on a observe, be it a racetrack or an autocross—and our figure-eight observe is actually a modified autocross (cones in a parking zone)—you generally is a little sloppy and it is no massive deal. Counterintuitive, I do know, however give it some thought. The typical racetrack is, what, 40 ft large? How large’s a single lane up on a mountain? 10 or 12 ft, tops. In case your automobile is not buttoned down, it will not be capable of transfer as shortly as a automobile that’s. Enter the RS6. None of us may push it as exhausting as we may the AMG. Then throw in a weird-feeling brake pedal and a few midcorner understeer, and, effectively of us, you’ve got acquired your self a second-place finisher on this two-car comparability check.

As for the AMG E63 S Wagon, wow. What a stonking, snarling, fuming, bloodthirsty animal of a automobile. It roars, claws out with its enamel bared in a method that few different automobiles do. The number of feelings this factor elicits from its driver is staggering in magnitude. You are terrified, wowed, impressed, shocked, after which giddy seemingly suddenly. Certainly one of our stock-in-trade sayings right here at MotorTrend is: driver confidence. On the finish of the day, the Audi would not instill a lot, whereas the Mercedes-AMG comes packing tons of it. Effectively, just a few dozen cubic ft, not less than.

Looks good! More details?
