Mike started his racing career at the age of 8 at Rye House in Hertfordshire. Since then, he has gone on to be the Formula A British Karting Champion, the Formula Renault Champion (2004) and the top British driver in the British Formula 3 Series, coming 3rd in 2005 with Fortec Motorsport.
In 2006, Mike raced in the British F3 International Series and had a phenomenal year. He dominated the championship and won the title with three races still remaining. It was also during this year that he won the Macau Grand Prix, becoming the first British driver to do so since 1999.
Mike moved to the GP2 Series in 2007 and spent the season racing for Super Nova Racing. He was also signed up to Honda F1 Racing as one of their test drivers. 2008 saw Mike remain in GP2 but this time he was racing with Trident Racing. At Monaco, he had his first 2008 podium when he took 1st place in the sprint race - a race which he led from start to finish.
2009 was Mike's rookie season in Indianapolis racing for Dreyer & Reinbold Racing in the Indy Racing League. He finished the championship in 17th place and recorded one top 5 finish and three top 10 finishes. Mike decided to stay in the US with Dreyer & Reinbold Racing for 2010 but a horrific, high-speed crash at the Indy 500 race meant he was unable to finish the rest of the season. Mike underwent intense rehabilitation and made a full recovery which meant he was fit for the start of the 2011 season. 2011 saw Mike join the Andretti Autosport team and just three races after his comeback he took his maiden Indy Car series win at Long Beach. 2012 saw a podium finish at the Streets of Toronto circuit with new team AJ Foyt Racing but towards the end of the season, Mike took the difficult decision to pull out from oval racing. As a result, 2013 sees Mike return to Europe to race with Delta-ADR in the World Endurance Championship; he will also make a return to Indy Car with Rahal Racing for selected races, the first being Long Beach.
