Second Hand Mercedes-Benz EQS Engine

The EQS is a fully electric vehicle, so it does not have a combustion engine in the traditional sense — the drivetrain is built around one or two electric motors depending on the variant, with the EQS 450+ using a single rear motor and the EQS 580 4MATIC using dual motors. When sourcing a replacement motor or drive unit, the motor part number and variant code (derivable from a VIN check) matter far more than the badge, because output ratings and configurations differ between single- and dual-motor setups. Always supply your full VIN or registration to the breaker so they can confirm the exact drive unit specification rather than going by model name alone.

The EQS (Z297 generation) launched in 2021 and covers the current production run, so a 2022 and 2023 car sit within the same generation without a major facelift boundary between them. In principle, drive units from the same variant — for example, both EQS 450+ or both EQS 580 4MATIC — are likely to share the same core motor assembly, but ancillary mounting details and software pairing can change quietly mid-production. Confirm the specific part numbers against your registration with the breaker before purchasing, as ECU and immobiliser coding to the vehicle is something only the breaker or a specialist can advise on for your exact car.

Trim levels like AMG Line and Exclusive are primarily cosmetic and equipment packages on the EQS; they do not change the underlying drivetrain specification. What determines the correct drive unit is the powertrain variant — EQS 450+, EQS 450 4MATIC, or EQS 580 4MATIC — not whether your car has AMG Line bodywork or Exclusive interior. You can expect cosmetic differences between donor and recipient cars to be irrelevant here, though you should still confirm part numbers with the breaker against your VIN.

These two variants have fundamentally different drivetrain layouts: the EQS 450+ is single-motor rear-wheel drive, while the EQS 580 4MATIC runs dual motors with all-wheel drive, so the drive units are not interchangeable. Attempting to fit a dual-motor assembly where a single-motor system was designed, or vice versa, would involve substantial differences in mounting, inverter hardware, and vehicle software. Always match the replacement unit to your car's exact powertrain variant, confirmed via VIN with the breaker.

The EQS is produced as a saloon (the core Z297 model), and this body style does not affect the specification of the electric motor or drive unit itself, which is determined by the powertrain variant. If a breaker is offering a drive unit from a donor EQS, the body style of that donor car is irrelevant to mechanical fitment. Focus your conversation with the breaker on matching the powertrain variant and confirming part numbers against your VIN rather than worrying about the donor vehicle's appearance.

Give the breaker your full VIN or UK registration, which will confirm your exact powertrain variant (450+, 450 4MATIC, or 580 4MATIC), model year, and any mid-production specification changes. The motor or drive unit part number from the donor car should then be cross-referenced against these details, as output and configuration differences between variants mean the badge alone is not enough to confirm fitment. ECU pairing and immobiliser coding are also factors the breaker will need to discuss with you, as these are vehicle-specific and cannot be confirmed in general terms.
