Group tests, debuts and road tests form the backbone of our Driving section. If you need an unbiased, thoroughly professional opinion on any 4x4 on Britain's roads today you'll find it here. Packed with details and thoughtful opinions, our group tests pit rivals back-to-back and emerge with an overall winner. Demanding and thorough, we test each vehicle to the limit and report exactly what we find back to you, the reader. Meanwhile, Debuts allow us to introduce any new 4x4s to you gently before we take them off-road and test them against their peers. We may be tough, but we're fair - you can trust our opinions.
