Let's Nerd Out About The Mercedes-amg One's Extremely Cool Drs-equipped Two-piece Active Rear Wing

One of my favourite cars astatine last weekend's Las Vegas Concours d'Elegance was this agleam yellowish Mercedes-AMG One, nan only 1 of its benignant astatine a show that was afloat of ample concentrations of 1 benignant of car. Only 275 of these F1-engined hypercars are group to beryllium built, pinch the first 1 having rolled disconnected nan statement successful 2022 and accumulation continuing connected arsenic we speak. (Or, I guess, arsenic you read.) The One not being road-legal successful nan U.S. speech from nether nan show and show rules makes them moreover much of an uncommon show — I'm still suspicious that our ain Collin Woodard sewage to spot 2 successful 1 place.

What made seeing this AMG One moreover amended is that it was successful 1 of nan "track-only" modes, either Race Plus aliases Strat 2, which hunkers down nan suspension by astir an inch and a half, folds up nan beforehand diffuser flaps, opens nan louvers connected nan beforehand fenders, and raises nan progressive rear wing. That past spot is what I'm present to nerd astir for you. I emotion cars pinch progressive rear wings, particularly erstwhile nan helping successful mobility is not conscionable functional and cool-looking, but nan existent system and moving parts look good, too. The AMG One is an fantabulous illustration of that. Its progressive aerodynamics helped it set nan accumulation car thigh grounds astatine nan Nürburgring, and they're a joyousness to get up adjacent to and look at, arsenic well.

In nan normal thrust modes nan AMG One's helping sits flush pinch nan rear deck, giving nan tail a bully profile. That shark fin extends disconnected nan backmost of nan ample tile scoop that's molded to nan carbon-fiber motor cover, which has a elephantine NACA duct connected either broadside and rear-facing louvers. I emotion that nan beforehand separator of nan rear helping has a accepted Mercedes badge connected it, particularly arsenic nan three-pointed prima connected nan One's chemoreceptor is airbrushed on.

The two-piece helping has a retractable leaf that slides rearwards astatine an angle, and nan full point tin flip up enactment arsenic an airbrake. Mercedes says that erstwhile the One has its aerodynamics successful its Track mode, downforce is accrued by up to 5 times depending connected nan speed, and full imaginable downforce generated by nan One is much than 1,500 pounds. Then there's nan DRS system, which is activated by pressing a fastener connected nan steering wheel.

DRS closes nan beforehand fender louvers and retracts nan precocious conception of nan wing, reducing downforce by astir 20% but expanding acceleration moreover further. The driver tin either move DRS disconnected manually, aliases nan car will automatically do it if it detects deceleration aliases a circumstantial magnitude of lateral acceleration, re-engaging nan progressive aero. On trial driver Maro Engel's 2nd Nürburgring thigh run, wherever he hit his first record by complete 5 seconds, he utilized DRS moreover much of nan time.

But man, conscionable look really cool nan arms for nan helping are! They're truthful complex, a operation of curves and consecutive lines pinch aggregate joints and bolts and mounting points. Plus, because nan AMG One's helping (and suspension) is hydraulically controlled, you get nan added play of those small hydraulic lines powering everything. It reminds maine of nan Bugatti Veyron's rear helping mechanism, which has moreover much artful but less-complicated arms. The AMG's helping tin extend, retract aliases set itself successful an instant.

The helping was nan root of a callback earlier this year, though. Back successful June, Germany's Federal Motor Transportation Authority recalled 219 AMG Ones built between December 12, 2022 and May 9, 2025, because nan hydraulic statement could beryllium missing a fistful of cotter pins, starring to a hydraulic fluid leak that could subsequently origin a occurrence if it landed connected a basking aboveground and ignited. Luckily location were nary reported fires owed to this issue, and nan hole only took an hr and a half.
