He bears the name of Australian motorsport royalty but Matthew Brabham is fast making his own racing mark, claiming his second successive title in IndyCar’s development program.

The 19-year-old grandson of triple Formula One world champion Sir Jack Brabham was on Sunday crowned Pro Mazda champion after winning both races at the Grand Prix de Trois-Rivieres in Canada.

The wins took Brabham’s tally for 2013 to a record 11, with two races still to go.

He also holds the record for the most consecutive wins in a season at seven, the most podiums in a season at 13, and is tied for the number of fastest race laps in a season at 11.

Sunday’s success has earned the third-generation driver a scholarship to advance to next year’s Indy Lights series – the third and final step towards the top-flight IndyCar championship.

He will become the first driver to graduate after winning the 2012 USF2000 and 2013 Pro Mazda titles in succession.

“I am absolutely speechless,” Brabham said.

“To get two wins and the championship makes this just an unbelievable weekend, and I couldn’t think of a better place to win the championship.

“At the start of the season, I couldn’t have predicted that I would have a year like this. I am just so, so happy.”

Brabham, whose father Geoff was a Le Mans 24 Hours winner and four-time IMSA champion, began his career in karting aged seven.

The Florida-born driver graduated to Formula Ford open wheelers in 2009 before winning the USF2000 title in his rookie year in the US.

Brabham’s last race weekend for the year will be at the Grand Prix of Houston on October 5.
