Cadillac Formula 1 team principal Graeme Lowdon says the needle between his team and Red Bull partner Ford "adds another layer of interest" to the series.
Cadillac is making its long-awaited F1 debut this year as an 11th expansion team, initially joining as a Ferrari customer outfit while working on its in-house power units in the US. Meanwhile, Ford is returning to the series as a power unit partner of Red Bull, which is producing its own engines in Milton Keynes with assistance from the Blue Oval.
