Product Overview

For sale is a complete Mercedes-AMG C43 engine, code 276.823, manufactured in 2017and recording just 3 kilometres — brand new in every practical and mechanical respect. This is the 3.0-litre twin-turbocharged V6 as fitted to the Mercedes-AMG C43 (W205/S205/C205), producing 270 kW (367 horsepower) and 520 Nm of torque. The engine is supplied complete with a comprehensive set of ancillaries as listed — including twin turbochargers, intercooler, oil pan, valve cover, alternator, starter motor, and all further accessories.

At 3 kilometres, this engine has experienced no operational use whatsoever.

This is not a used engine in any meaningful sense; it is a brand-new unit at a significant saving to new Mercedes dealer supply.

About the Mercedes-AMG C43 276.823 Engine

The Mercedes M276 biturbo V6 — code 276.823 in AMG C43 specification — is the twin-turbocharged 3.0-litre six-cylinder petrol engine that powers the C43 AMG across all its body variants. It is the engine that defines the C43’s position as a genuine performance AMG model rather than simply a tuned C-Class — producing 270 kW (367 hp) and 520 Nm, with a 0–100 km/h time of approximately 4.7 seconds in the W205 body.

The M276 biturbo in C43 specification uses a twin-scroll twin-turbocharger arrangement calibrated by AMG for improved response and a wider torque band compared to the standard M276 used in non-AMG Mercedes applications. The result is a V6 that delivers strong, progressive performance from low RPM through to the redline, with a refinement and sound character that complements the C43’s premium-performance positioning.

The 276.823 is also used across the AMG 43 range in related applications — including the E43 AMG (W213) and GLC43 AMG — making this engine code relevant to a wider buyer audience than C43 alone. Buyers from related platforms should confirm their engine code matches 276.823 before purchasing.
