Speed City is the most unique motorsports radio broadcaster in the USA – providing racing content on both four and two wheel international motorsports including Formula 1, FIAWEC, MotoGP , World Superbikes, the Macau GP, the Toyota Racing Series and American motorsports including Indycar, MotoAmerica and the IMSA series.

Our mission is to connect the dots and tell the story of what’s happening in International motorsport at the highest level to what’s emerging at the grassroots level in the USA. From Moto GP’s Valentino Rossi to upcoming future stars such as American Joe Roberts. We discuss and report on Haas F1 team and their emergence as a Formula One contender while introducing our audience to the next F1 American stars such Haas junior driver Santino Ferrucci and RedBull Junior Neil Verhagen.

In 2018 we announced a partnership with SiriusXM radio and Formula 1.


Through a multi-year agreement with Formula 1, SiriusXM will broadcast all Formula 1 races this season. Listeners nationwide will hear the BBC 5 Live radio broadcast for each event with Speed City providing the American voice for F1 with pre- and post- races show for every Grand Prix. Hosted by Jon Massengale, Les Kiser and veteran motorsport TV commentator and host Jonathan Green, the shows will air in the hour before and after every Formula 1 race this season. They will analyze the action, discuss the talking points of each race and then throw it out to the American fans of the Sport to give their take on this lively call in talk show which give its audience all news, views and opinions of all things Formula 1. Back in 2012 our first guest on the show in 2012 was an unknown American racing GP2 in Europe – We told his story as he become the first American since Scott Speed to gain an F1 Super licence before racing in F1 at COTA . California’s rising star Alexander Rossi went on to win the 2016 Indy 500 and Speed City covered the event live from Indy and he continues to be a regular guest on the show.

Our team at Speed City is uniquely poised to do this, given that we have forged relationships with F1, MotoGP, FIAWEC, Indycar, and more. We also have access to some of the biggest names in motorsports broadcasting including one of the best, our own Jonathan Green.

With Jonathan Green presenting and commentate races across the USA and around the world, the host team of Speed City’s Jon Massengale and Les Kiser will anchor the broadcasts from Austin, Texas and will be on-site at major events at American venues like Circuit of The Americas.
