| Model | Generation | Built |
|---|---|---|
| BMW G90 M5 | M5 | 2024– |
In the G90 M5 (2024–), the S68B44 powered the M5. Engines from other models fit the G90 as long as the sump, mounts and ancillaries match, which we check against your VIN.
Common S68B44 problems
The S68B44 shares its weak points with the rest of the S68 family. These are the faults to check on a used unit and on your own engine. The full explanation of each is in the S68 guide.
| Known fault | What to check |
|---|---|
| Limited history | Ask for the donor car's mileage and accident report. |
| Accident damage | Inspect the front of the engine and the wiring harness. |
Limited history. The S68 is too new for clear failure patterns to have emerged.
S68B44 maintenance
- 0W-30 BMW Longlife-01 or 17 FE+.
- Oil every 10,000 km or yearly.

Buying a used S68B44: checklist
- Compression or leak-down figures. Even compression across all cylinders tells you more than mileage. Ask for the figures, not just a pass or fail, and compare the highest and lowest readings: a spread above 10 to 15 percent deserves a question.
- Photographs from every side. Good suppliers photograph the actual engine you will receive. Look for the block stamp, the sump, the timing cover and any broken brackets or connectors in the pictures.
- List of what is fitted. Engines are sold with different ancillaries: some have the turbo, injectors, manifolds, alternator and starter, others are long blocks. Agree the list in writing so you know which parts must come from your old engine.
- Look at the oil and coolant. Clean oil without metal particles and coolant without oil are good signs. Milky oil, oily coolant or a burnt smell mean the engine needs further checks before it is fitted.
- Warranty terms in writing. Read what the warranty covers, how long it runs and what fitting conditions apply. Most warranties require a qualified workshop, new fluids and filters, and replacement of the cooling parts that caused the original failure.
- Turbocharger shaft play and oil. Rotate the compressor wheel by hand. A small amount of side play is normal; in-and-out play or wheel contact with the housing is not. Oil pooled in the intake or intercooler pipes points to worn seals.
- Timing chain noise. Listen for a rattle at the front of the engine for the first seconds after a cold start. On an engine that cannot be run, look at the chain guides through the oil filler or with the valve cover off.
- Injectors and high-pressure fuel pump. Direct-injection engines rely on high-pressure pumps and precise injectors. Ask whether the injectors are original or updated and whether there were fuel pressure faults.
- Bearing and valve clearance history. M engines are built to tighter tolerances. Ask for the last rod bearing replacement and valve clearance check, and consider an oil analysis if the engine can be run.
- Both cylinder banks. On a V engine, check compression, plugs and coils on both banks. Faults on one bank alone are common and easy to miss on a quick test.
- Hybrid system compatibility. Mild-hybrid engines are matched to their starter-generator and battery systems. Confirm compatibility with your car's equipment before ordering.
Questions about the S68B44
Will the S68B44 engine fit my BMW F95 X5 M?

Are there other versions of the BMW S68B44?
In our yard the S68B44 is the only listed version of the S68 family. It makes 430 kW (585 HP) and 750 Nm, and was built from 2022 to 2026.
Engines in one family share a basic block, but the turbo, the injection, the sensors and the engine computer can differ. A higher power version often has different pistons, a bigger turbo or a different fuel system.
This is why we ask for the exact code. Fitting a different version can work, but the wiring, the software and sometimes the gearbox must be changed to match.

How much power and torque does the BMW S68B44 have?
From the factory the BMW S68B44 makes 430 kW (585 HP) and 750 Nm of torque. It is a 4.4 liter (4,395 cc) V8, DOHC, 32 valve petrol engine with twin turbochargers.
Because it is turbocharged, the torque comes in low in the rev range, which makes the car feel strong in everyday driving. A healthy turbo, a clean intercooler and tight boost pipes are key to getting the full figure.
A used engine reaches its factory numbers when it is fitted with the matching engine computer and software, and serviced with the right oil and filters. If the engine computer from your car is a different version, a specialist may need to code it.
Every S68B44 on our site lists its year and mileage. Ask the desk for more pictures of any listing. We are happy to show the stamp, the ports and the ancillaries before you decide.

What comes with a used S68B44 engine?
Each S68B44 is sold as described on its own listing. The yard writes down the parts that are fitted to that unit, such as the turbo, the injectors, the manifolds or the alternator, so you know what arrives.
Some units are long engines with few ancillaries, others are more complete. If you need a part that is not listed, ask the desk. We often have the matching items in the yard.
Every engine is drained, sealed at each opening, strapped to a heat-treated pallet and shrink-wrapped, then photographed before it leaves the yard.
On delivery, the carrier brings the pallet to the kerb or a loading bay. Please have a forklift, a pallet truck or an engine crane ready.

How do I know a used S68B44 engine is in good shape?
The photos on each listing show the actual engine, not a stock picture. The yard checks the code, records what is bolted on, and seals the openings before the engine is offered. An inspection certificate for the unit can travel with the order when you ask for it.
When you look at a listing, check the recorded mileage, the year and the photos of the ports and the stamp. Ask for photos of anything you want to see closer. If you want more photos or a short video of a unit, ask the desk and we send them before you pay.
On a petrol engine like the S68B44, a careful fitter will also look at the spark plugs, the coils and the timing side before the engine goes in.
If the engine fails inside under normal use, the warranty covers you. Eligible engines come with a 12 months warranty from the delivery date. It covers internal mechanical failure under normal use and correct fitting by a qualified mechanic or workshop.

Which cars use the BMW S68B44 engine?
BMW fitted the S68B44 to the BMW G09 XM, BMW F95 X5 M, BMW F96 X6 M and BMW G90 M5. These cars were built with this engine from about 2022 to 2026.
The badge on the boot is not enough to be sure. The same model name can hide two different engines, for example after a facelift or a change in emission rules. Always read the engine code stamped on the block, or look it up with your VIN.
The S68B44 is the only S68 version we list, which makes it easy to pick, but the wiring and the engine computer still need to match your car.

What should I replace when I fit a used S68B44 engine?
A used engine lasts longest when it starts life in your car with fresh fluids and new seals. Clean the intercooler and the intake pipes, and fill the turbo oil feed with clean oil before the first start, so the turbo never runs dry. Fit a new oil filter and fresh oil of the grade BMW lists for this engine, and refill the coolant with the correct BMW antifreeze mix. Use new gaskets for the exhaust manifold, the intake and the sump plug, and check every hose clip before the first start.
Look at the engine mounts and the clutch or the torque converter while the engine is out. Old mounts can crack a new engine's brackets, and a worn clutch is much easier to change now.
Before the first start, turn the engine over without fuel until the oil pressure light goes out. Then let it idle, check for leaks, and drive gently for the first few hundred kilometres.
The warranty asks for fitting by a qualified mechanic and the correct oil, coolant and filters. Keep your receipts in case you ever need to make a claim.

How much does a used BMW S68B44 engine cost?
A used BMW S68B44 engine in our yard usually costs between 11.550 € and 17.450 €. The exact price depends on the year, the mileage and the parts that come with the engine.
Our units show recorded mileage from about 22,000 km up to around 200,000 km. Lower mileage and more ancillaries mean a higher price. Each listing shows its own price, and the price you see is the price you pay. Prices include VAT for private buyers.
Shipping is a flat 249 € per order. It is added once at checkout and printed on the invoice, so there is no extra fee later. If you order a gearbox or a second engine on the same order, the fee is still charged once.
Inside the EU there is no import duty. For the UK and other non-EU countries, import duty and local VAT are paid by the receiver, and we supply a commercial invoice.

Is the BMW S68B44 a diesel or petrol engine?
The S68B44 is a petrol engine. It is a 4.4 liter (4,395 cc) V8, DOHC, 32 valve unit with twin turbochargers, and it was built to the Euro 6 emission standard.
The emission standard matters for registration and for low-emission zones in many cities. When you replace an engine with the same code, the car keeps the same paperwork and the same emission class.
Petrol versions need the correct catalytic converters and oxygen sensors on the car to stay legal and to keep the engine computer happy. Reuse the parts from your car if they are in good condition.
If you are not sure which version you need, send us your VIN. We tell you the right code for free.
