The 2007 Mercedes-Benz SL65 AMG Was a Crazy Luxury Muscle Car

TL;DR

The SL65 AMG packs a twin-turbo V12 with 604 hp and 738 lb-ft of torque into a refined luxury convertible that cost nearly $200,000 new.

Key Points

• 1.Powertrain: 6.0L twin-turbo V12 producing 604 hp and 738 lb-ft of torque — numbers that were monstrous in 2007 and still impressive today, housed in a hand-built engine signed by its AMG craftsman.
• 2.Price context: The SL65 stickered just under $200,000 in 2007 (over $300,000 in today's money), compared to the entry-level SL500 at ~$95,000 with only 300 hp.
• 3.Famous engine sibling: This same twin-turbo V12 powers the Pagani Huayra supercar, making it one of the most celebrated engines in modern automotive history.
• 4.Exterior distinctions: The SL65 is subtly differentiated from lesser SLs by unique dark gray riveted wheels, a "V12 Biturbo" badge, and exclusive gill vents above the front wheels.
• 5.Quirky interior features: Includes seat-mounted storage compartments, luggage seat belts in the rear parcel shelf, an early seat massage function, and a roll bar you manually raise at the cost of aesthetics.
• 6.Unusual controls: The convertible top and roll bar are both operated by a single hinged center-console flap; the engine can be started by either a traditional key or a button on the shift lever.
• 7.Roof system: The power-retractable hardtop includes a built-in glass sunroof panel with a sunshade; a trunk shelf physically limits luggage height to ensure the roof can still fold down.
• 8.Doug Score: 59/100 — docked for being neither practical enough as a daily nor sporty enough as a weekend car, but praised for its extraordinary powertrain value and effortless high-speed performance.
