Proton Gen-2, built to the then-new
NGTC regulations. He competed in the final half of the season from
Snetterton onwards, finishing 22nd in the Drivers' Championship, having secured his first BTCC point at the penultimate race of the season at
Silverstone. Welch continued to race in the BTCC in 2012. He had his best weekend of the season at
Oulton Park, finishing sixth in Race 1 and then holding off
