Williams chief technical officer Paddy Lowe thinks the Chinese Grand Prix will give a "truer measure" of 2017's pecking order.
The Australian Grand Prix marked the beginning of Formula One's new era, which features wider cars and tyres aimed at dramatically reducing lap times. Sebastian Vettel's win in Melbourne also suggested a change at the front, with Ferrari living up to pre-season hype by beating Mercedes at the season opener.
Williams finished the race as 'best of the rest', leading the tightly-packed midfield group of teams behind Ferrari, Mercedes and Red Bull. Lowe thinks this weekend's race in Shanghai, part of a back-to-back with the Bahrain Grand Prix, will give the team a better idea of where it really sits in that battle.
