Mercedes-Benz C 63 AMG (W205) Engines for Sale | Engine Finders

The Mercedes-AMG C 63 (W205), launched for 2015, moved AMG's flagship C-Class from a naturally aspirated V8 to a twin-turbocharged one: the 4.0-litre M177, built in-house at Affalterbach under AMG's 'one man, one engine' approach.

Mercedes-Benz C 63 AMG (W205) Replacement Engines

A replacement M177 restores the C 63's dual character, sharp response with the broader torque spread that turbocharging brings, while retaining the hand-built quality that distinguishes AMG's own engines from mainstream Mercedes-Benz units.

C 63 AMG (W205) Models & Engine Codes

Two tunes exist across the W205 generation: the standard C 63 at about 476 PS, and the C 63 S at about 510 PS. Both share the M177 code, so confirm the exact rating (and price expectation) from the engine number, not the badge alone, before ordering a replacement.

Buy Used and Second-Hand Mercedes-Benz C 63 AMG (W205) Engines

Given the M177's cost and complexity, buyers considering a used unit should weigh inspection, provenance and warranty carefully against a reconditioned unit; the price gap is often smaller than it first appears once those costs are accounted for.

Mercedes-Benz C 63 AMG (W205) Engines in Stock

We work with UK suppliers who carry reconditioned M177 units for both C 63 and C 63 S specifications. Give us your registration and engine number and we will confirm current stock.

Warranty for Replacement Mercedes-Benz C 63 AMG (W205) Engines

Warranty terms are set by the individual supplier, typically 12 months, and should be confirmed in writing, alongside what work and ancillaries are included in the quoted price.

Expert Tips for Choosing the Right Engine for Your Mercedes-Benz C 63 AMG (W205)

Confirm standard vs S tune

  • A roughly 34 PS gap separates the two; match your engine number, not just the badge.

Ask what ancillaries are included

  • Turbos, intercoolers and wiring looms can be a significant extra cost if not included.

Get the warranty terms in writing

  • Confirm length and what it covers before paying a deposit.

Check whether VAT is included

  • Ask each supplier directly; the published price alone does not state this.

When your engine fails, Mercedes-Benz C 63 AMG (W205) engine works can restore performance at a fraction of the cost of a brand-new engine. Facts for this page are drawn from Mercedes-Benz technical press material, Wikipedia and specialist automotive press (autoevolution, 500sec.com), not from a parts-catalogue lookup.

Frequently Asked Questions - Mercedes-Benz C 63 AMG (W205) Engines
What engine is in the C 63 AMG (W205)?

The W205-generation C 63 uses AMG's M177: a hand-built, twin-turbocharged 4.0-litre V8, replacing the naturally aspirated M156 of the previous generation.

What is the difference between the C 63 and C 63 S engine?

Both use the same M177 block. The standard C 63 is rated about 476 PS (469 hp) and 650 Nm; the C 63 S is retuned to about 510 PS (503 hp) and 700 Nm. Match the exact rating, not just the badge, before ordering.

How much does a reconditioned M177 engine cost?

Our current price for a reconditioned M177 is £9,000, taken directly from our approved pricing sheet. Contact us for a firm quote against your exact engine number.

Is the M177 the same engine used in the AMG GT?

It's the same engine family (M176/M177/M178), but the AMG GT and GT 4-Door Coupé use different states of tune and, in some applications, the higher-output M178. Codes and ratings differ, so do not assume interchangeability.

Does the M177 fit the C 63 estate and coupé as well as the saloon?

Yes, the same M177 and rating structure applies across the W205 saloon, S205 estate and C205 coupé.

What replaced the naturally aspirated M156 in the C 63?

AMG moved from the naturally aspirated M156 (W204) to the twin-turbocharged M177 for the W205 generation, trading some of the M156's high-revving character for a broader torque curve and better efficiency.

Are there known issues with the M177 engine?

We have not found catalogue-grade documented issue reports specific to this application that we are prepared to publish here. That is not a claim the engine is problem-free; ask your supplier what inspection was carried out.

Can I buy a used M177 engine instead of a reconditioned one?

Used units do appear, typically from donor or written-off cars, but a reconditioned unit with a warranty is usually the safer buy given the M177's complexity and cost. We can help you weigh both options.

Do all W205 C 63 cars use petrol, or is there a diesel version?

The C 63 AMG badge is petrol-only; the W205 range also offered diesel C 220 d / C 250 d models under different engine codes (OM651/OM654), which are separate pages on our site.

What warranty comes with a reconditioned M177 engine?

Warranty terms are set by the individual supplier, typically around 12 months. Always confirm this, and what it covers, in writing before you commit.
