The first details surrounding Honda’s new-specification Formula 1 engine have emerged after it ran on track for the first time. Honda’s new F1 power unit made its track debut during an Aston Martin filming day at the Hungaroring on Wednesday, ahead of its planned introduction at next month’s Dutch Grand Prix. There was promise for Aston Martin in the race too, with Lance Stroll and Alonso beating both Cadillacs, Haas and Williams cars, and an Alpine on their way to 13th and 14th respectively. Further gains are expected to come with Honda’s new power unit when it makes its race weekend debut at Zandvoort. So, it's the first part of our planned upgrade," Newey said during Friday’s FIA press conference in Hungary.
