Aston Martin Red Bull Racing's decision to switch engine supplier from Renault to Honda will come into force at the start of the 2019 F1 season. Mobil 1 The Grid spoke exclusively to the team's Chief Technical Officer, Adrian Newey, to find out more about the plan to join forces with the esteemed Japanese manufacturer and, in particular, to understand the impact of the move for dedicated fuel and lubricant supplier Mobil 1.

Whether it be a manufacturer switch or a driver change, Stewart-Haas Racing has overcome several challenges in recent years. And in 2018, it has started the Monster Energy NASCAR season in emphatic style. During the series' west coast swing, team leader Kevin Harvick starred with a hat-trick of victories, while new arrival Aric Almirola burst out of the blocks, almost winning the Daytona 500. Mobil 1 The Grid caught up with Harvick, Almirola, team-mates Clint Bowyer and Kurt Busch, and team boss Tony Stewart to assess SHR's growth.
