This is the new Aston Martin DBX first drive review. Aston's 550hp twin turbo V8 SUV offers class leading head room, leg room and boot space in a design that is to my eyes the best looking SUV ever made! The DBX benefits from 3 cylinder air suspension, a technology allowing it to have a massively broad spectrum of ability both on and off road. Performance is 0-62 in 4.5 seconds and a top speed of 181mph and with the highest power output from it's 48v anti-roll system in the industry, when you show the DBX a corner the chassis stays flat and gives you so much confidence to enjoy a great driving road too. Could this just be the world's best SUV?
