Opel Astra 2002 vs BMW Z4 2006
| Gearbox: | Manual | Manual | |
|---|---|---|---|
| Engine: | 2.2 Diesel | 2.0 Petrol | |
| Diesel (Opel Astra) 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 (BMW Z4) 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." | |||

Performance | |||
| Power: | 125 HP | 150 HP | |
| Torque: | 280 NM | 200 NM | |
| Acceleration 0-100 km/h: | 9.9 seconds | 8.2 seconds | |
|
BMW Z4 is a more dynamic driving. Opel Astra engine produces 25 HP less power than BMW Z4, but torque is 80 NM more than BMW Z4. Due to the lower power, Opel Astra reaches 100 km/h speed 1.7 seconds later. | |||
Fuel consumption | |||
| Fuel consumption (l/100km): | 6.3 | 7.5 | |
| Real fuel consumption: | 6.2 l/100km | 7.6 l/100km | |
|
The Opel Astra is a better choice when it comes to fuel economy. By specification Opel Astra consumes 1.2 litres less fuel per 100 km than the BMW Z4, which means that by driving the Opel Astra over 15,000 km in a year you can save 180 litres of fuel. By comparing actual fuel consumption based on user reports, Opel Astra consumes 1.4 litres less fuel per 100 km than the BMW Z4. | |||
| Fuel tank capacity: | 52 litres | 55 litres | |
| Full fuel tank distance: | 820 km in combined cycle | 730 km in combined cycle | |
| 1010 km on highway | 980 km on highway | ||
| 830 km with real consumption | 720 km with real consumption | ||
| Opel Astra gets more mileage on one fuel tank. | |||

Drive type | |||
| Wheel drive type: | Front wheel drive (FWD) | Rear wheel drive (RWD) | |
| Front-wheel drive cars (Opel Astra) have better traction on slippery roads and when climbing hills, better fuel economy, and are less expensive to purchase. On the disadvantage side, FWD cars usually have less towing capacity, poorer acceleration and harder handling. Rear-wheel drive cars (BMW Z4) have better handling on dry roads, better acceleration, more even weight distribution and more fun to drive. RWD is also better for towing large loads. The cons of rear-wheel drive are less interior and trunk space and more difficulty maneuvering in wet and snowy conditions. | |||
Engines | |||
| Average engine lifespan: | 480'000 km | 420'000 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 Opel Astra engine could be longer. | |||
| Engine production duration: | 5 years | 11 years | |
| Engine spread: | Installed on at least 3 other car models, including Opel Zafira, Opel Vectra, Opel Signum | Installed on at least 4 other car models, including BMW 3 sērija, BMW 1 sērija, BMW X3, BMW X1 | |
| In general, the longer and for more car models an engine is produced, the better its serviceability and availability of spare parts. BMW Z4 might be a better choice in this respect. | |||
Dimensions | |||
| Length: | 4.27 m | 4.09 m | |
| Width: | 1.71 m | 1.78 m | |
| Height: | 1.39 m | 1.30 m | |
| Opel Astra is 18 cm longer than the BMW Z4, 7 cm narrower, while the height of Opel Astra is 9 cm higher. | |||
| Trunk capacity: | 330 litres | 240 litres | |
|
Opel Astra has more luggage capacity. Opel Astra has 90 litres more trunk space than the BMW Z4. | |||
| Turning diameter: | 11 meters | 9.8 meters | |
| The turning circle of the Opel Astra is 1.2 metres more than that of the BMW Z4, which means Opel Astra can be harder to manoeuvre in tight streets and parking spaces. | |||
| Power steering: | Hydraulic power steering | Electric power steering | |
| Hydraulic power steering is technologically more complex, louder, increases fuel consumption and requires more servicing. It has the advantages of more power, less strain on the car's electrical system and better feedback (feeling) when steering. | |||

| Safety: | no data | no data | |
| Quality: | average | above average | |
| BMW Z4 has fewer problems. According to annual technical inspection data Opel Astra has serious deffects in 20 percent more cases than BMW Z4, so BMW Z4 quality is probably better | |||
