UNUSUAL CARS MODEL GUIDE
The W211 Mercedes-Benz E55 AMG combined a supercharged 5.4-litre M113K V8 with understated E-Class bodywork. Introduced in 2002, it delivered 350 kW (476 PS) and 700 Nm through a five-speed automatic, and was available as both a saloon and the exceptionally rapid S211 estate.
Quick answer: The E55’s M113K engine is robust when maintained, but age makes intercooler-pump performance, supercharger cooling, engine mounts, oil leaks, transmission servicing, Airmatic suspension and SBC braking history essential checks. Estate-specific rear suspension and tailgate equipment add further complexity.
Why AMG supercharged the W211 E-Class
The W211 arrived with extensive electronic and chassis technology, but the AMG flagship’s defining feature was its belt-driven supercharger. It gave the E55 immediate torque and effortless pace without the high-rev character of the later naturally aspirated E63. The discreet visual treatment made the performance particularly surprising.
M113K V8 and five-speed automatic
The 5,439 cc M113K V8 used an intercooled supercharger to produce 350 kW (476 PS) and 700 Nm. AMG retained the durable five-speed automatic because it was better suited to the torque than the contemporary seven-speed unit. The combination is strong, but cooling, fluid condition and correct servicing remain critical on cars now two decades old.
Main versions and specifications
| Version | Powertrain or distinction | Guide note |
|---|---|---|
| E55 AMG saloon | 350 kW / 476 PS; 700 Nm | Understated four-door performance model |
| E55 AMG estate | Same M113K powertrain | Rare high-performance S211 load carrier |
| Later E63 AMG | Naturally aspirated M156 V8 | Different engine and seven-speed transmission |
Saloon and S211 estate
Both body styles share the core powertrain and Airmatic-based chassis. The estate adds a huge load area and rear self-levelling requirements, turning it into one of the era’s most capable fast estates. UK buyers should verify specification, because equipment, brakes and trim can vary with market and options.

How the E55 differs from the later E63
The 2006-on E63 AMG replaced the supercharged M113K with the naturally aspirated 6.2-litre M156 and used a seven-speed transmission. The E63 revs higher and has a different character; the earlier E55 is defined by low-rev supercharged torque and the five-speed automatic.
Mercedes E55 AMG W211 buying guide
Check that the auxiliary intercooler pump works and that intake temperatures remain controlled under sustained load. Inspect supercharger pulleys, belts, engine mounts, rocker-cover leaks and cooling components. The transmission needs evidence of fluid and filter changes. Test every Airmatic height and damper setting, look for overnight sinking and inspect compressor duty. Confirm SBC brake recall and service history, then test electronics, climate control, seat functions and estate tailgate equipment.
Why it matters
Few cars combine supercar-rivalling torque, family space and such discreet styling. The estate in particular remains one of AMG’s most unusual and desirable practical performance cars.
