There’s something almost absurd about piloting a 791-horsepower plug-in hybrid luxury sedan down one of the most treacherous stretches of coastal highway in North America. But that’s exactly what Car and Driver’s Elana Scherr did, road-tripping the 2026 Mercedes-AMG S63 E Performance from Los Angeles to San Francisco along Highway 1. The resulting photo essay tells us more about this car’s true character than any spec sheet ever could.
The S63 E Performance is a contradiction on wheels. It’s a sub-10-second drag car wrapped in Amaretto Brown nappa leather and offering massage chairs with ocean views. It packs a twin-turbocharged V-8 mated to a plug-in hybrid system that, while delivering brutal acceleration, eats into trunk space by raising the cargo floor.
For a flagship sedan that starts well north of $180,000, that’s a compromise most buyers probably won’t notice. Their luggage is being shipped ahead anyway.
But Scherr didn’t take the typical AMG owner’s approach to this drive. Instead of checking into the $2,000-a-night Alila Ventana spa, she landed at Fernwood, a decidedly more humble Big Sur establishment, after her original reservation fell through. The juxtaposition of a quarter-million-dollar automobile parked among redwoods at a campground-adjacent resort is exactly the kind of real-world context these cars almost never get.
Highway 1 is a road that demands respect. Rockslides close it regularly, bridges get damaged, and fuel stops along the central coast stretch are sparse and expensive. It’s not a route you’d instinctively choose for a car this wide, this heavy, this expensive.
But that’s precisely what makes this particular road trip so revealing. The S63 E Performance isn’t just a straight-line weapon or a boardroom shuttle. It apparently handles the tight, crumbling-edge switchbacks of Big Sur with enough composure that the driver was more focused on photographing sea lions than white-knuckling the steering wheel.
Mercedes offers more than 50 paint options through its Manufaktur customization program for the 2026 S63, and Scherr’s example happened to match the California sky. That’s an unintentional flex that underscores how much this car is designed to be seen. The V-8 badge on the fender is becoming a genuine rarity in an era where even AMG has pivoted hard toward electrification, making the S63’s biturbo 4.0-liter something of a rolling monument to an engine layout that’s rapidly aging out of production.
The optional executive rear-seat package plus — because of course there’s a “plus” version — adds massaging bucket seats, an oversized rear console, and temperature-controlled cupholders. It’s the kind of feature list that sounds excessive until you’ve spent six hours on a winding two-lane highway and realize the car has been quietly working to keep you from feeling any of it.
What matters here, beyond the glamorous photography and the scenic backdrop, is what the S63 E Performance represents for Mercedes-AMG’s future. This is likely one of the last AMG flagships to carry a combustion V-8 of any kind. The hybrid system bolted to it isn’t just an emissions compliance tool — it’s a bridge between the thundering AMG sedans of the past two decades and whatever all-electric successor Stuttgart eventually rolls out.
The fact that it can demolish a drag strip, massage your lumbar on a conference call overlooking the Pacific, and navigate a road that regularly defeats lesser vehicles says something about the engineering ambition packed into this platform. It’s excessive, impractical in certain ways, and completely unnecessary for anyone who just needs to get from L.A. to San Francisco.
That’s entirely the point. Cars like the S63 E Performance have never been about need. They exist at the intersection of capability and desire, where a V-8 howl meets electric torque fill and the leather smells like money.
Highway 1 just happens to be the perfect stage to prove that even in the twilight of the combustion era, Mercedes still knows how to build a grand tourer that makes the journey feel more important than the destination. The road was open. The car was willing. Sometimes that’s all the justification you need.
