The Last of the Twin-Turbo V12 Titans, 2016 Mercedes-Benz S65 AMG

4 min read

In an era where efficiency increasingly trumps excess, the 2016 Mercedes-Benz S65 AMG stands as a magnificent anachronism. This is the automotive equivalent of ordering the most expensive bottle on the wine list simply because you can, a hand-built twin-turbocharged V12 luxury sedan that prioritizes presence over practicality. When Mercedes decided to stuff 621 horsepower into their flagship sedan, they weren’t thinking about fuel economy or environmental responsibility.

The Heart of Excess

At the core of the S65 AMG beats a 6.0-liter twin-turbocharged V12 engine that represents everything magnificent and terrible about automotive excess. Hand-assembled by AMG technicians in Affalterbach, this powerplant produces 621 horsepower and an earth-moving 738 lb-ft of torque. The numbers tell only part of the story, though. It’s the delivery that sets this engine apart from lesser mortals.

Unlike the more common V8-powered S63 AMG, the V12 in the S65 operates with a smoothness that borders on supernatural. There’s no drama in the power delivery, no crescendo of sound and fury. Instead, the S65 simply gathers speed with the inevitability of a freight train, propelling its considerable mass from 0-60 mph in just 4.2 seconds. The experience is less about excitement and more about inexorable forward progress.

Luxury Redefined

Step inside the S65 AMG and you’re greeted by an interior that represents the pinnacle of German luxury craftsmanship. The cabin is swathed in the finest Nappa leather, with diamond-quilted seats that offer massage functions across 14 different programs. The dashboard features real wood trim and aluminum accents, while the ambient lighting system can be customized to match your mood or the time of day.

The technology package is equally impressive. The dual 12.3-inch displays handle everything from navigation to entertainment, while the Burmester surround sound system transforms the cabin into a concert hall. The air suspension system doesn’t just provide a smooth ride, it actively scans the road ahead and adjusts the damping accordingly. Even the seats can detect an impending collision and automatically adjust to optimize safety.

Driving Dynamics

Despite weighing over 4,800 pounds, the S65 AMG manages to feel surprisingly nimble when the road turns twisty. The AMG-tuned suspension strikes an impressive balance between comfort and control, while the rear-wheel-drive configuration provides a more engaging driving experience than the all-wheel-drive S63. The steering is appropriately weighted and surprisingly communicative for a car of this size and luxury focus.

The seven-speed AMG transmission shifts with the precision of a Swiss timepiece, though it can be caught napping during sudden throttle inputs. In Comfort mode, the S65 transforms into the ultimate grand tourer, wafting along highways with minimal road or wind noise. Switch to Sport+ mode, and the exhaust note deepens to a cultured growl while the suspension firms up noticeably.

The End of an Era

The 2016 S65 AMG represents something of a farewell tour for naturally aspirated excess in the luxury sedan segment. With increasingly stringent emissions regulations and the march toward electrification, hand-built V12 engines are becoming an endangered species. Mercedes has since discontinued the S65 in favor of more efficient alternatives, making this generation a collector’s item in waiting.

Living with the S65 AMG requires a certain philosophical approach to fuel consumption. EPA estimates suggest 13 mpg city and 21 mpg highway, though real-world driving rarely achieves even those modest figures. The carbon fiber engine cover bears the signature of the technician who assembled your particular engine, a personal touch that reminds you this is as much art as transportation.

The S65 AMG represents automotive craftsmanship at its most uncompromising, a hand-built monument to the philosophy that more is always better. In a world increasingly focused on efficiency and electrification, this twin-turbo V12 luxury sedan stands as a glorious reminder of what happens when engineers are given unlimited budgets and told to create something truly special. It’s excessive, impractical, and absolutely magnificent.

  1. That’s impressive engineering, though I have to say after spending time in my 993 Turbo and 996 GT2, there’s something about naturally aspirated power delivery that just feels more connected on track. The S65’s 621hp is undeniably brutal for a sedan, but I wonder how much of that gets lost to turbo lag in real world driving versus the raw immediacy you get from a proper high-revving engine.

  2. ngl the s65 is insane but paul kinda has a point about that NA feeling, like theres something special about it even if turbos are objectively faster lol. question tho – how much of that 621hp is actually useable day to day or does it just sorta sit there cause the car weighs a million pounds? im broke so i cant afford to find out but seems like one of those situations where you’re paying for bragging rights more than you’re paying for fun

    • Yeah Ben, I feel you on that – we’ve dynoed enough twin-turbo stuff to know that peak numbers don’t tell the whole story, especially in a 4,600 lb sedan. The S65 makes solid mid-range torque so it’s not totally useless day to day, but you’re right that most of that power lives up top where you’ll never realistically use it on public roads. Honestly, if someone came to my shop asking about maximizing daily fun in a big luxury car, I’d tell them the naturally aspirated stuff is easier to live with because you get usable power everywhere instead of waiting for boost.
