BMW Z4 2006 vs Opel Astra 2002
| Gearbox: | Manual | Manual | |
|---|---|---|---|
| Engine: | 2.0 Petrol | 2.2 Diesel | |
| Petrol engines (BMW Z4) are generally quieter, smoother, and better suited for short trips due to quicker warm-up times. Diesel (Opel Astra) engines, on the other hand, offer superior fuel efficiency and torque, making them ideal for long-distance driving and heavy loads.

Drive type | |||
| Wheel drive type: | Rear wheel drive (RWD) | Front wheel drive (FWD) | |
| 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: | 420'000 km | 480'000 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: | 11 years | 5 years | |
| Engine spread: | Installed on at least 4 other car models, including BMW 3 sērija, BMW 1 sērija, BMW X3, BMW X1 | Installed on at least 3 other car models, including Opel Zafira, Opel Vectra, Opel Signum | |
| 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. | |||

Opel Astra has more luggage space. BMW Z4 has 90 litres less trunk space than the Opel Astra. | |||
| Turning diameter: | 9.8 meters | 11 meters | |
| The turning circle of the BMW Z4 is 1.2 metres less than that of the Opel Astra, which means BMW Z4 can be easier to manoeuvre in tight streets and parking spaces. | |||
| Power steering: | Electric power steering | Hydraulic power steering | |
| Electric power steering is simpler, quieter, more fuel-efficient, more configurable and provides additional features such as auto-steering for lane assist and parking. The disadvantages of electric power steering are possible overheating under prolonged load conditions and insufficient feedback (feeling) during steering. | |||
