Mercedes Benz S350d STANDARD

Highlights

• 0–100 km/h in 6.0 seconds
• 5.4 L/100km combined fuel consumption
• 510 litres boot space

Summary

This 2018 S350d represents a smart entry point into flagship luxury, balancing the prestige of the S-Class with the exceptional efficiency of Mercedes' OM656 inline-six diesel engine. With 150,000 km over 8 years, its mileage is exactly in line with typical GCC highway use, where these diesel powerplants are known for their long-distance durability. The black exterior remains the most sought-after resale color in the region, ensuring the car holds its value better than lighter or more niche shades. While rivals often prioritize tech, this S-Class stands out for its ride quality and vault-like cabin insulation. For a GCC buyer, the primary consideration is the refined torque available for effortless overtaking on long stretches like the E11 or the highway to Riyadh.

This Car vs Other 2018 S350ds

At 150,000 km, this vehicle has averaged approximately 18,750 km per year, which is lower than the typical 20,000–25,000 km average seen in the GCC. This makes it a mechanically fresh example for its age, especially given that diesel engines in this segment are built for high-mileage endurance. The black paintwork is a significant asset for local resale, as it is the most requested color for executive sedans in the UAE and Saudi markets.

STANDARD vs Lower Trims

As the base for the facelifted W222 generation, this trim still includes essential GCC luxuries like the Widescreen Cockpit and ambient lighting as standard. It benefits from the 9G-TRONIC transmission and AIRMATIC air suspension, features that are often optional on lower-tier executive cars. Unlike earlier V6 models, this 2018 version features the more refined and powerful inline-six engine, a major upgrade for serious buyers.

S350d vs Segment Rivals

The S350d competes directly with the BMW 730d and Audi A8 50 TDI, leading the group in overall ride suppleness and cabin quietness. Its 70-litre fuel tank paired with the diesel powertrain offers a massive highway range, often exceeding 1,200 km, which far outclasses petrol rivals on cross-border drives. While the 7 Series focuses on a firmer, driver-centric feel, the S-Class remains the segment benchmark for rear-seat comfort and passenger serenity.

Running Costs & Resale

The S350d is remarkably frugal for a luxury flagship, achieving roughly 5.4 L/100km on combined cycles, though GCC stop-start city traffic will see this closer to 6.6 L/100km. Mercedes-Benz has an extensive authorized service network across the UAE, Saudi Arabia, and Kuwait, ensuring parts are readily available even for Korean-spec imports. While European luxury sedans typically depreciate by 12–18% annually in the GCC, the diesel S-Class maintains a loyal niche following among long-distance commuters, stabilizing its mid-term value.

Performance & Capability

The 286 hp inline-six engine delivers a stout 600 Nm of torque from as low as 1,200 rpm, allowing for a 0–100 km/h sprint in 6.0 seconds. This low-end grunt is ideal for the UAE's fast-moving highways, providing effortless acceleration without the high-rev drama of a petrol engine. The top speed is electronically governed at 250 km/h, and the rear-wheel-drive setup ensures a classic, balanced luxury car feel through the steering.

Comfort & Cabin

The cabin is a sanctuary of high-grade materials and advanced insulation designed to keep the 45°C GCC summer heat at bay. Standard dual-zone climate control and a high-efficiency air filtration system are particularly effective against regional dust. With 510 litres of boot space, it easily accommodates airport runs or golf bags, while the 5-seat layout provides class-leading legroom even in the standard wheelbase configuration.

Safety

This S-Class features a robust suite of safety tech including Active Brake Assist and Attention Assist, which are invaluable for staying alert on long desert highway stretches. The Pre-Safe system prepares the cabin for a collision by tightening belts and closing windows, while the standard 9 airbags provide comprehensive passenger protection. Its stability control is finely tuned to manage traction on both tarmac and the occasional sandy road shoulder.

The bottom line

This is the ideal choice for a professional who prioritizes fuel efficiency and long-range comfort without sacrificing the prestige of the S-Class badge. Given its market-aligned mileage and high-demand color, it represents one of the most practical ways to own a modern S-Class in the GCC today.
