Speedworks Motorsport Tom Ingram has made a return to the top-step of the British Touring Car Championship podium after dominating a safety car interrupted final race at Knockhill.

The Toyota Avensis driver twice saw his advantage wiped out by safety car phase but managed to hold on for his third win of the 2017 campaign ahead of Honda's Gordon Shedden.

It was Ant Whorton-Eales who successfully led the opening lap-and-a-half from pole position but the Audi driver's stint in the lead proved to be short lived after having a huge moment at the Arnold Clark Chicane.

That subsequently handed Tom Ingram the lead while Whorton-Eales peeled into the pits with his damaged AmD Tuning.com Audi at the end of the second lap.

Meanwhile, it was reigning champion Gordon Shedden, who was the man on a move after picking his way through from seventh to end the fifth lap in second position.

However, whilst the race order was settling, the Toyota Avensis of Ingram romped away at the front and enjoyed a near seven-second gap back towards the chasing Honda Civic Type-R of Shedden by the end of the tenth lap.

Instead of hunting down Ingram, Shedden was forced to turn his attentions to Team BMW's Rob Collard and Colin Turkington in third and fourth, both lapping quicker than the leading Speedworks Avensis.

Indeed, Collard managed to get past Shedden on lap 17, but the reigning champion quickly returned the favour and muscled his way back past with a trademark lunge at Clark corner.

However, just as Ingram thought he was safe, a late safety car wiped out his nine-second lead. But the Toyota driver wasn't to be denied and bolted away from the chasing pack as soon as the safety car toured back into the pits.

Instead, attentions turned back to the battle for second, with Shedden hanging on ahead of the BMWs.

Shedden's cause was helped by another safety car period as marshals recovered Will Burns' damage stricken Volkswagen CC.

Indeed, Shedden held on for second position ahead of Team BMW's Turkington while Subaru's Ashley Sutton grabbed fourth at the line ahead of his fellow BMR team mates James Cole and Jason Plato in fifth and sixth.

The Subaru trio benefited from Collard's late race demise after a brief yet significant trip to the gravel cost the BMW driver vital championship points and subsequently dropped down to eleventh behind Mat Jackson, Matt Neal, Rory Butcher and Dave Newsham.

Butcher's ninth place finish was his second consecutive top-ten finish on what proved to be a highly profitable weekend for the BTCC debutant.
