Welcome to the On Grid Podcast, with our hosts, Tiff Needell and Paul Woodman.  
This week, Formula 1 is back with testing in Formula 1. We had a thrilling finish in Formula E in Cape Town, plus Superbikes in Australia, NASCAR in Fontana and more!  Firstly, we pay our respects to Musician and Formula 1 driver, Slim Borgudd, who was the drummer for Abba, too!  
In Formula 1 news, Haas have reduced the number of seats on their pitwall, saving a whopping $250,000! Elsewhere, F1 teams are now expecting £60 million per team for a new team to join the sport. Rumours also suggest that Red Bull maybe selling the Alpha Tauri team.   
We've seen F1 testing in Bahrain, but which do you think is the best looking livery on the new cars?  
In Cape Town, South Africa, we had an exciting Formula E race.   
The other big race was in World Superbikes, at Phillip Island in Australia.  
Over the pond in Fontana, we had NASCAR.  
Next week, we have Formula 1 in Bahrain, Indycar in St. Petersburg, more World Superbikes in Indonesia, and NASCAR in Las Vegas!
