Big, brawny V8s, screaming tires and high-speed circuit driving. No, it’s not a supercar showdown - it’s…an SUV comparison? In the case of these two rather extraordinary SUVs, that’s precisely what’s on offer. Ride along with the gang at Fifth Gear as they test the two mega-SUVs back-to-back on the course at Anglesey.
