The engine number on a Mercedes-Benz S600 in the UAE is typically stamped on a machined pad on the engine block, most commonly on the right-hand side (passenger side in left-hand drive GCC-spec vehicles) near the connection point with the transmission. For the common W222 generation S600 sold here, you'll often find it by looking from the top of the engine bay downwards towards the firewall, or from underneath the vehicle near the bell housing. It's a critical identifier for registration with the RTA Dubai or MOI UAE, especially during vehicle inspection, ownership transfer, or when ordering specific parts that differ from the S500 variant common on UAE roads.
While both the S600 and the more popular S500 in the UAE share the same body, the engine is the key differentiator for authorities and workshops. The GCC-spec S600 (model years up to 2020) used a 6.0-liter V12 biturbo engine producing 530 hp and 830 Nm of torque, compared to the S500's 4.7-liter V8 biturbo with 455 hp and 700 Nm. You will need to provide this engine number precisely for any official process.
| Specification | Mercedes S600 (GCC-spec, up to 2020) | Mercedes S500 (GCC-spec, common comparison) |
|---|
| Engine Code | M279 | M278 |
| Displacement | 5980 cc | 4663 cc |
| Power | 530 hp | 455 hp |
| Torque | 830 Nm | 700 Nm |
| Typical Avg. Fuel Economy (City, Special 95) | 4.2 - 4.8 km/l | 5.8 - 6.5 km/l |
- Fuel Consumption: Owners report averages between 4.2 to 4.8 km/l in Dubai city traffic, with highway driving on the Dubai-Abu Dhabi road reaching up to 7 km/l.
- Official Registration: The RTA Dubai requires the engine number for all registration and renewal processes.
- Cost Implication: The V12 engine significantly impacts long-term costs, from higher fuel expenses using Super 98 to more costly specialized servicing.
Calculating the total cost here is stark. Based on 15,000 km annual driving with fuel at 3.20 AED/l for Super 98, annual fuel cost exceeds 11,000 AED for the S600—nearly double that of an S500. Annual depreciation for a used 2018 S600 in the UAE can be 55,000-70,000 AED, as per major dealership evaluations, making the cost per km very high compared to the V8 model. Data on used valuations aligns with market reports from 2023-2024. The MOI UAE's vehicle database uses this number to verify the vehicle's powertrain specifications during ownership transfers. The high power and torque figures are suited for stable high-speed cruising on UAE highways, but the low fuel economy is a major consideration for local drivers.
