2002 Mercedes-Benz S500 Review: The Definitive Guide to the W220 Flagship
The 2002 Mercedes-Benz S500 represents one of the most consequential chapters in S-Class history. Positioning itself as the volume flagship of the W220 generation, the S500 combined a 5.0-liter V8 with cutting-edge electronics and a silhouette that still turns heads more than two decades later. But beneath the prestige lies a complex machine — one that rewards informed buyers and punishes the careless. This analysis examines every dimension of the 2002 S500: engineering, performance, known failure points, ownership costs, and competitive standing — so you can decide with confidence whether this classic German grand tourer belongs in your garage.
Key Takeaways at a Glance
- Engine: The M113 5.0L V8 delivers 302 horsepower and 339 lb-ft of torque — smooth, torquier, and far more refined than the earlier 5.8L V12 alternative.
- Performance: 0–60 mph in approximately 6.0 seconds; a governed top speed of 130 mph (electronically limited).
- Transmission: Robust 5G-Tronic 5-speed automatic (722.6) — widely regarded as one of the best automatic transmissions Mercedes ever built.
- Reliability red flags: Airmatic suspension compressor and valve block failures, throttle body carbon buildup, and rear differential seal leaks are the three most common—and most expensive—issues.
- Interior luxury: The W220 introduced COMAND APS, Burmester surround sound, and heated/ventilated seats as premium options, setting a new benchmark for cabin technology in 2002.
- Current value: Well-maintained examples range from $8,000 to $18,000 depending on mileage, condition, and service history — making this a compelling entry point into the S-Class ecosystem.
- Verdict: A 2002 S500 is an excellent buy if and only if you budget $3,000–$5,000 annually for maintenance and can source a vehicle with complete service records.
Engine & Performance Analysis
The M113 5.0-Liter V8
At the heart of the 2002 S500 sits the M113E50 engine — a 4,966 cc DOHC 32-valve V8 featuring individual throttle bodies per cylinder (a design carried over from the racing-derived M119). This architecture produces a remarkably linear power delivery curve, with peak output of 302 hp at 5,400 rpm and 339 lb-ft of torque available from 350 rpm to 4,500 rpm. The low-end torque character makes the S500 feel effortlessly swift in real-world driving, even though the official 0–60 mph time of roughly 6.0 seconds places it firmly in the "luxury cruiser" band rather than the sports sedan realm.
Compression ratio is a modest 10.3:1, tuned for reliability rather than peak output. The engine is fundamentally overbuilt, with a cast-iron block and aluminum cylinder heads, and is capable of exceeding 200,000 miles with disciplined maintenance. Oil change intervals should not exceed 5,000 miles or six months — Mercedes' original "Assyst" system is notoriously permissive and using it as a guide will shorten engine life.
Transmission & Drivetrain
Power reaches the rear wheels through the 722.6 five-speed automatic — affectionately known among enthusiasts as the "5G-Tronic." Despite its aging architecture, this unit is renowned for bulletproof durability when serviced regularly with Mercedes-approved ATF (MB 236.14 specification). Shift quality is generally crisp, and the transmission's adaptive learning algorithm keeps shift points appropriate to driving style. Key service items: fluid and filter change every 40,000 miles; valve body inspection at 100,000 miles.
The S500 uses a conventional rear-wheel-drive layout with a multi-link independent suspension at all four corners. No all-wheel-drive variant was offered in the S500 trim for the 2002 model year.

Suspension, Chassis & Ride Dynamics
Airmatic DSP: Innovation and Liability
The 2002 S500 came standard with the Airmatic DSP (Digital Service Program) air suspension system — a double-wishbone front and multi-link rear setup with adaptive damping control. On well-maintained examples, the ride quality is genuinely world-class: isolating road imperfections while retaining enough body control to feel composed through corners. This is the suspension that made the W220 feel half a class above its competitors on broken roads.
However, Airmatic is the single greatest liability for prospective owners. The compressed-air system includes four air springs (bellows), a central compressor, a moisture-separator valve block, and height-sensing struts. Over time, the rubber bellows develop micro-cracks and lose pressure; the compressor motor wears out from excessive duty cycles; and the valve block develops internal leaks. A full Airmatic overhaul — all four bags, compressor, and valve block — routinely costs between $4,500 and $7,000 at a specialist shop, or $2,500 to $4,000 in parts alone for a competent DIYer.
