2006 Mercedes-Benz S65 AMG: Unleash the Power of a V12, Without Breaking the Bank
For those who crave the raw power and exhilarating sound of a V12 engine, but don’t want to pay a fortune, the 2006 Mercedes-Benz S65 AMG presents a compelling proposition. This performance-oriented luxury sedan delivers a potent combination of power, refined features, and impressive handling, all available at a surprisingly accessible price point.
V12 engines, once a staple of high-performance vehicles, are becoming increasingly rare. While smaller, more efficient engines dominate today’s automotive landscape, the allure of a V12—with its signature smooth power delivery and distinctive roar—remains undeniable. The S65 AMG offers a unique opportunity to experience this automotive icon without the often-prohibitive cost associated with such engines. At the time this article was compiled, you can find used models with an average auction price below $25,000.
For a vehicle that originally retailed at approximately $200,000 new, the depreciation has been significant, but that means you can obtain a super-powered performance machine at an incredible bargain.
Performance and Powerhouse
The heart of the S65 AMG is its hand-built, twin-turbocharged 6.0-liter V12 engine. This powerhouse generates an impressive 604 horsepower and 737 lb-ft of torque. This translates to blistering acceleration, with 0-60 mph times in the mid-4-second range. This performance rivals many modern sports cars, demonstrating the remarkable engineering of the engine. The performance does have a tradeoff when it comes to fuel economy, achieving a combined MPG rating of 14. This will cost you an average of $4,400 each year in gas.
The engine employs a twin-turbocharger system, with each turbo supplying compressed air to one bank of six cylinders. The turbos use a journal-bearing design for optimized spool time and thermal efficiency, and an air-to-water intercooler further ensures consistent power delivery. Inside, the engine features a forged steel crankshaft, fracture-split connecting rods, and lightweight aluminum pistons. The AMG-designed engine management system precisely controls ignition timing and fuel injection.
“The performance and handling do not come at the expense of refinement. Under hard acceleration, there’s a distant whooshing from the turbochargers accompanied by a muted growl from the V12.” – Owner review of their 2006 Mercedes-Benz S65 AMG on Car Survey.org
AMG Tuning and Handling
The S65 AMG is not just about straight-line speed; it also delivers impressive handling thanks to AMG’s expertise. The car features Mercedes’ Active Body Control (ABC) suspension, which AMG has tuned for quicker responses. This hydraulic system actively combats body roll and dive, keeping the sedan remarkably flat in corners despite its weight (4,894 pounds).
AMG also stiffened the dampers and lowered the ride height for a sportier feel, while the chassis is reinforced for extra rigidity. The rear multi-link setup was revised for better grip. The S65 AMG is equipped with sliding caliper composite brakes, a wide track, and sticky tires, enhancing its performance capabilities.
Race-Worthy Transmission
To complement the potent engine and refined suspension, the S65 AMG features an AMG SPEEDSHIFT five-speed automatic transmission with DIRECT SELECT. This transmission has reinforced internals to handle the engine’s torque and power. SPEEDSHIFT tuning provides quick and sporty gear changes, and there are three selectable drive modes—Manual, Sport, and Comfort—to tailor the driving experience.
A Luxurious and Commanding Presence
Inside, the S65 AMG offers a luxurious and inviting environment. The interior features polished burr walnut trim, comfortable leather upholstery, and ergonomically designed AMG sports seats. The driver-centric cockpit includes easy-to-read dials and an AMG-specific steering wheel with integrated paddle shifters. Additional features include air conditioning, AMG door sills, an optional RACETIMER, and an exclusive analog IWC Ingenieur clock.
On the exterior, the S65 AMG projects an undeniable road presence. The front end features large air intakes, flared wheel arches housing 19-inch lightweight multi-spoke alloys, and sleek side skirts. The rear showcases quad exhaust pipes and a rear diffuser, further emphasizing the car’s performance capabilities.
The Bottom Line
The 2006 Mercedes-Benz S65 AMG offers a rare combination of blistering performance, opulent luxury, and a surprisingly affordable price. For those seeking a high-performance sedan with a V12 engine, the S65 AMG represents an exceptional value. It’s a chance to experience the thrill of a legendary engine without the typical high cost associated with such vehicles.
