Mercedes S class 1999 vs Subaru Impreza 1998
| Gearbox: | Automatic | Manual | |
|---|---|---|---|
| Engine: | 3.2 Diesel | 2.0 Petrol | |
| Diesel (Mercedes S class) engines typically outperform gasoline engines in terms of fuel efficiency and low-end torque. This makes them more economical and better suited for towing or long-distance travel. However, gasoline (Subaru Impreza) engines mostly are lighter, quieter, and offer better acceleration and responsiveness, especially in smaller vehicles. For more information, see the article "Diesel or Petrol: Fuel Economy and Key Differences." | |||
| Camshaft drive: | Timing chain | Timing belt | |
| Engine chain usually needs to be replaced less often than the timing belt, but the cost of replacing the chain is usually higher. Chain motors are considered to be more reliable, but noisier and more vibration generating. | |||
Performance | |||
| Power: | 197 HP | 125 HP | |
| Torque: | 470 NM | 184 NM | |
| Acceleration 0-100 km/h: | 8.5 seconds | 9.4 seconds | |
|
Mercedes S class is more dynamic to drive. Mercedes S class engine produces 72 HP more power than Subaru Impreza, whereas torque is 286 NM more than Subaru Impreza. Thanks to more power Mercedes S class reaches 100 km/h speed 0.9 seconds faster. | |||
Fuel consumption | |||
| Fuel consumption (l/100km): | 8.9 | 9.0 | |
| Real fuel consumption: | 8.9 l/100km | 9.2 l/100km | |
|
By specification Mercedes S class consumes 0.1 litres less fuel per 100 km than the Subaru Impreza, which means that by driving the Mercedes S class over 15,000 km in a year you can save 15 litres of fuel. By comparing actual fuel consumption based on user reports, Mercedes S class consumes 0.3 litres less fuel per 100 km than the Subaru Impreza. | |||
| Fuel tank capacity: | 88 litres | 50 litres | |
| Full fuel tank distance: | 980 km in combined cycle | 550 km in combined cycle | |
| 1230 km on highway | 690 km on highway | ||
| 980 km with real consumption | 540 km with real consumption | ||
| Mercedes S class gets more mileage on one fuel tank. | |||

Drive type | |||
| Wheel drive type: | Rear wheel drive (RWD) | All wheel drive (AWD, 4x4) | |
Engines | |||
| Average engine lifespan: | 560'000 km | 380'000 km | |
| Engine resource depends largely on regular maintenance and the quality of the oils and fuels used, but under equal conditions the average life of a Mercedes S class engine could be longer. | |||
| Engine production duration: | 4 years | 7 years | |
| Engine spread: | Used also on Mercedes E klase | Installed on at least 2 other car models, including Subaru Forester, Subaru Legacy | |
| In general, the longer and for more car models an engine is produced, the better its serviceability and availability of spare parts. Subaru Impreza might be a better choice in this respect. | |||
| Hydraulic tappets: | yes | no | |
| The Mercedes S class engine has hydraulic tappets (lifters), providing quieter operation and no need for periodic adjustment, but they are more complex in design and can cause serious engine damage in case of failure. | |||
Dimensions | |||
| Length: | 5.04 m | 4.35 m | |
| Width: | 1.86 m | 1.69 m | |
| Height: | 1.44 m | 1.42 m | |
|
Mercedes S class is larger. Mercedes S class is 69 cm longer than the Subaru Impreza, 17 cm wider, while the height of Mercedes S class is 2 cm higher. | |||
| Trunk capacity: | no data | no data | |
| Turning diameter: | 11.7 meters | 10.6 meters | |
| The turning circle of the Mercedes S class is 1.1 metres more than that of the Subaru Impreza, which means Mercedes S class can be harder to manoeuvre in tight streets and parking spaces. | |||
| Gross weight (kg): | 2`100 | 1`000 | |
| Safety: | no data | no data | |
| Quality: | above average | above average | |
| Subaru Impreza has slightly fewer faults. Deffect rate in annual technical inspection is similar for both cars, it's slightly higher for Mercedes S class, so Subaru Impreza quality could be a bit better. | |||
| Average price (€): | 5800 | 5600 | |
