As Chevrolet celebrated its 13th consecutive NASCAR manufacturers' title in 2015, Toyota was planning its own dominant streak. It was already working on the 2018 Camry for the road and the '17 NASCAR Cup series, but few predicted it would end up being accused of Formula 1 dominance by the end of the year.
During Chevrolet's stranglehold on the series, Toyota's debut season in 2007 was described as "humbling" by senior management. The nadir was only four cars qualifying for the Daytona 500 - it brought eight - and none finished higher than 22nd.
Since then, it's committed to pumping money into the NASCAR programme and relentlessly bringing significant updates. From 2013 onwards, it introduced a virtually new car every two years. A first manufacturers' title came in 2016, but '17 was when Toyota threatened to truly dethrone Chevrolet.
