Every engine fitted to the S213 estate specifically — including the 2020 facelift that brought the M256 inline-six and M264 four-cylinder with EQ Boost.
Overview
Mercedes E-Class S213 — Overview
The S213 is the estate variant of Mercedes-Benz's fifth-generation E-Class (W213), introduced in 2016 as the successor to the S212 estate.
Built on the MRA platform, it brought significant weight savings, advanced semi-autonomous driving tech, and — with the E 63 S — the most powerful estate Mercedes had ever built. A 2020 facelift introduced the new M256 inline-six petrol engine (replacing the M276 V6) and the M264 four-cylinder with EQ Boost, alongside significant interior and technology updates.

Best & Worst Engines
Best Diesel Overall
OM656.929 (E 400 d)
“The 2.9-litre inline-six diesel delivers 330 bhp and 700 Nm of torque — effortless, refined, and the most powerful six-cylinder diesel in the range. Injector and AdBlue system issues are emerging as its only real demands.”
Who it's for: buyers who want six-cylinder diesel refinement without the V8's fuel bills.
Best Petrol Overall
M256.930 (post-2020 E 450 / E 53)
“The 3.0-litre inline-six with EQ Boost is a masterpiece — smooth, responsive, and with the 48V mild-hybrid system filling the torque gaps. It replaced the M276 V6 and is genuinely better in every way.”
Who it's for: buyers who want the most advanced petrol engine in the range.
Highest Risk
M274.920 (pre-2020 E 200/E 300)
“The 2.0-litre turbo four is a solid engine, but it was superseded by the M264 for good reason — carbon buildup and HPFP issues are known weaknesses on higher-mileage examples.”
Who it's for: budget-conscious buyers who accept the older tech.
Most Expensive Failure
M177.980 (E 63/E 63 S)
“The 4.0-litre twin-turbo V8 delivers up to 612 bhp in S form, but the hot-vee layout concentrates heat between the cylinder banks — valve cover oil leaks and coolant system issues are the most common, with full replacement costs reaching £16,000.”
Who it's for: AMG buyers with deep pockets and full service history.
Best Value
OM654.920 (E 220 d / E 300 d)
“The 2.0-litre four-cylinder diesel offers genuine economy (50+ mpg) with the reliability of Mercedes' modern common-rail system — and avoids the ageing OM651's injector seal issues entirely.”
Who it's for: buyers who want a modern, efficient estate without the V6 or V8 premium.
Most Overlooked
M276.823 (E 400/E 450, pre-2020)
“The 3.0-litre twin-turbo V6 is often overshadowed by the newer M256, but it offers genuine performance (5.2s to 60mph) with well-understood, manageable maintenance costs. Timing chain stretch is the main concern, but it's a known fix.”
Who it's for: buyers who want V6 performance without the newer engine's premium.
Mercedes E-Class S213 — Ownership Economics
The S213 rule
A £2,800–£5,000 OM654 recon against a £12,000–£25,000 S213 sits at 10–40% of the car's value — well within our 70% Mercedes-Benz threshold. Even the £8,000–£16,000 M177 V8 recon against a £30,000–£60,000 E 63 is just 25–50% — a viable spend on a well-maintained example. These are modern, valuable cars; replacement almost always makes financial sense.
Key Takeaways
Which S213 Costs Least To Own?
E 220 d (OM654) — cheapest diesel recon, best fuel economy.
Which S213 Costs Most To Own?
E 63 S — V8 replacement and hot-vee maintenance costs.
Which S213 Is Best Value?
E 300 d (OM654) — modern diesel with 194 bhp and excellent economy.

Core Variants
Core Variants
Scope note: All variants listed are S213 estate only (2016–2023). W213 saloon, C238 coupé and A238 cabriolet share most of these engines but are covered on their own Generation Pages, since fitment and labour access vary slightly by body style. The E 300 e and E 350 e are plug-in hybrids; the E 300 de is a diesel plug-in hybrid.
