UNUSUAL CARS MODEL GUIDE
The Mercedes-Benz E63 AMG W212 was sold from 2009 to 2016 as the flagship of the fourth-generation E-Class. It began with AMG’s 6.2-litre naturally aspirated M156 V8 and later switched to the 5.5-litre twin-turbo M157, creating two distinctly different versions of the same understated performance saloon and estate.
Quick answer: Choose the early 6.2 for response, sound and mechanical character, or the later 5.5 biturbo for stronger mid-range torque and easier tuning potential. In either case, buy on documented maintenance, engine condition, transmission behaviour, suspension, brakes, tyres and accident-free bodywork.

From M156 to M157
Mercedes-Benz introduced the W212 E-Class in 2009 and followed quickly with the E63 AMG rated at 386 kW (525 PS). Early cars use the 6,208 cc M156 V8, a high-revving naturally aspirated engine paired with AMG’s seven-speed MCT transmission. From 2011, the 5.5-litre twin-turbo M157 replaced it, retaining 525 PS in standard form but producing substantially more torque.

Saloon, estate and facelift differences
Both saloon and estate bodies were offered, making the S212 one of the era’s fastest practical estate cars. The 2013 facelift changed the E-Class nose from four separate lamp shapes to a smoother two-lamp treatment, updated driver-assistance technology and introduced the most powerful S model. Drivetrain availability differed by country, so UK buyers should verify the exact factory specification from the VIN and data card rather than relying on an advert.
Engine and transmission checks
For an early M156 car, obtain proof of correct servicing and specialist inspection. Listen from cold, check for oil or coolant leaks and investigate any misfire, tapping or warning light. On M157 cars, inspect the cooling and intake systems, look for leaks around turbo-related plumbing and confirm that software or exhaust modifications are declared and professionally executed. The seven-speed MCT should engage cleanly and shift consistently in every mode.
Mercedes E63 AMG W212 buying guide
Check the underside, arches, door bottoms, boot area and suspension mounting points for corrosion or poor repairs. Uneven panel gaps, mismatched paint and incorrect fasteners may indicate accident damage. These cars consume tyres and brakes quickly when used hard; budget for premium replacements and check that wheel sizes and tyre specifications match.
On a road test, confirm straight tracking, quiet suspension, strong braking without vibration and stable engine temperature. Test every electronic system, including climate control, seats, parking aids, navigation and tailgate operation on estates. A complete history from recognised specialists matters more than a low odometer reading.
Which W212 E63 is best?
The 6.2-litre car is the purist choice and the rarer configuration because its production window was short. The biturbo is faster in normal driving and usually more economical, while the facelift adds modern equipment and the most powerful factory specification. The best buy is the most original, best-documented example within budget.
