BMW 1 series 2007 vs Opel Astra 2007
| Gearbox: | Manual | Manual | |
|---|---|---|---|
| Engine: | 2.0 Diesel | 1.7 Diesel | |
| 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: | 143 HP | 101 HP | |
| Torque: | 300 NM | 240 NM | |
| Acceleration 0-100 km/h: | 9 seconds | 12 seconds | |
|
BMW 1 series is more dynamic to drive. BMW 1 series engine produces 42 HP more power than Opel Astra, whereas torque is 60 NM more than Opel Astra. Thanks to more power BMW 1 series reaches 100 km/h speed 3 seconds faster. | |||
Fuel consumption | |||
| Fuel consumption (l/100km): | 4.5 | 5.1 | |
| Real fuel consumption: | 5.8 l/100km | 6.1 l/100km | |
|
The BMW 1 series is a better choice when it comes to fuel economy. By specification BMW 1 series consumes 0.6 litres less fuel per 100 km than the Opel Astra, which means that by driving the BMW 1 series over 15,000 km in a year you can save 90 litres of fuel. By comparing actual fuel consumption based on user reports, BMW 1 series consumes 0.3 litres less fuel per 100 km than the Opel Astra. | |||
| Fuel tank capacity: | 51 litres | 52 litres | |
| Full fuel tank distance: | 1130 km in combined cycle | 1010 km in combined cycle | |
| 1270 km on highway | 1200 km on highway | ||
| 870 km with real consumption | 850 km with real consumption | ||
| BMW 1 series gets more mileage on one fuel tank. | |||
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 1 series) 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. | |||
| Ground clearance: | 145 mm (5.7 inches) | 160 mm (6.3 inches) | |
| Because of the higher ground clearance, Opel Astra can perform better on bad roads - it can go over higher obstacles and bumps. At the same time, the higher ground clearance can reduce stability and handling on paved roads, especially at higher speeds. Note, however, that this Opel Astra version does not have 4x4 drive, which is very important in poor road conditions. | |||
Engines | |||
| Average engine lifespan: | 350'000 km | 560'000 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: | 17 years | 7 years | |
| Engine spread: | Installed on at least 6 other car models, including BMW 5 sērija, BMW 3 sērija, BMW X3, BMW X1 | Installed on at least 3 other car models, including Opel Meriva, Opel Corsa, Opel Combo | |
| In general, the longer and for more car models an engine is produced, the better its serviceability and availability of spare parts. BMW 1 series might be a better choice in this respect. | |||
| Hydraulic tappets: | yes | no | |
| The BMW 1 series 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. | |||
