Auto Buyers Guide gives the 2026 Mercedes Maybach SL 680 a positive 72/100 rating, praising its exceptional performance and build quality—the SL63 e-performance hits 0-60 in 2.5 seconds with 805 horsepower, and the construction quality impresses throughout. The cabin technology scores well with directional air vents that are "their favorite in the US right now," though the dashboard screen is disappointingly identical to standard Mercedes models for a $230,000 vehicle. The real drawbacks are the nearly unusable rear seats (only 14-16 inches for passengers) and brutal value proposition—the reviewer notes the car costs more than the 13 acres it sits on, making it objectively poor from a value perspective. This is an exclusive, thrilling convertible for wealthy buyers seeking status and performance over practicality or financial sense.

TheStraightPipes gave the 2026 Mercedes-Maybach SL 680 a solid 78.1/100 rating, praising its flawless performance and technology—the handcrafted twin-turbo V8 delivers 577 hp and 590 lb-ft with genuinely quick acceleration, while the infotainment system wisely combines hard buttons with wireless CarPlay and luxury touches like the air scarf neck heater. However, the ride quality falls short of Maybach expectations, with reviewers finding the suspension stiff and uncomfortable even in Maybach mode, likely exacerbated by the large 21-inch wheels. The vehicle itself is undeniably special and powerful, though TheStraightPipes acknowledged it can feel somewhat embarrassing to actually be seen in—starting at $315,000 CAD, it's best suited for luxury buyers who want extreme performance and opulence without worrying about subtlety.
