There are very few small 4x4s. The technology is heavy and expensive - and, crucially, has a negative impact on fuel economy and CO2 emissions. We'd recommend a two-wheel-drive car with a set of winter tyres for most uses. If you really need a 4x4, we rate the Toyota Yaris Cross highly - it's a small SUV with hybrid power and available with all-wheel drive. The Dacia Duster is a good alternative, particularly if you're on a budget.
