Driver Focus

Before there was a Rush SR championship, there was Blair Hosie—RAW co-founder, factory test driver, and the original “Rush Stig.” With nearly a decade behind the wheel, Blair has logged countless development laps refining every aspect of the SR’s performance.

In 2024, Blair emerged from his development role to battle wheel-to-wheel with the best. At Road America, he finished just 0.006 seconds behind James French—the closest finish in GridLife history. At Lime Rock, he traded blows with Ryan Leach all weekend, scoring two wins and two seconds.

2025 saw Blair step up to a full championship effort, finishing P4 overall with 4 wins and 13 podiums. When he’s not racing, he’s coaching customers and providing after-sales support—because at Rush Auto Works, the people who build the cars also race them.
