Pundit and commentator Will Buxton compared the character and driving styles of the pair, labelling Hamilton as the faster driver with more natural ability, but with an intellect to match Rosberg's. Buxton wrote: "Man to man against Rosberg, I can't recall a single race this year where in the same machinery Hamilton's fuel usage has been higher. He has made his tires last. He has had to fight from the back of the field time and again (think Germany, think Hungary) and yet he hasn't overworked his tires, he hasn't used too much fuel. He has learned how to drive these new cars, and to extract the most from them using the least [...] Far from the unintelligent chancer many paint Hamilton to be, he is proving to be the intellectual match of his teammate and, the better racer to boot". Their old karting boss, Dino Chiesa, said Hamilton was the faster driver whereas Rosberg, who once said to Chiesa "everything relates to physics and maths", was always more analytical. This led some to believe that Rosberg would achieve greater success in Formula One, the highest level of open-wheel racing, due to the intellectual capacity required to manage brakes, energy harvesting, tyre management and moderate fuel usage. However, Hamilton's tyre management has frequently allowed him to push on for longer, often enabling optimum race strategies, and his fuel usage has regularly been better than almost anyone on the grid. Sky Sport's Mark Hughes, commented "Rosberg has a more scientific methodology, looks to fine-tune more specifically than Hamilton who typically tends just to find a balance he can work with, then adapt his driving around it".
