Drive type | |||
| Wheel drive type: | Front wheel drive (FWD) | Rear wheel drive (RWD) | |
| Front-wheel drive cars (Opel Signum) 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. | |||
