‘Shadowhunters’ Alum Katherine McNamara Brings Star Power to the Speedway in Bold Racing Gear

Katherine McNamara was all smiles on Instagram on Thursday, February 26, giving fans a front-row look at her high-speed world.

The Shadowhunters alum and Arrow actress, 30, shared a series of snapshots from the racetrack as she geared up for the upcoming IndyCar season, teasing that it was “almost time” for the 2026 season to start.

In the photos, McNamara leaned fully into race-day style. She sported a black-and-orange racing suit adorned with sponsor patches, including Chevrolet and NTT IndyCar branding. The tailored fit and bold color blocking gave the look a sharp, athletic edge, while black racing boots completed the head-to-toe ensemble. In one shot, she posed inside a garage space, holding a lanyard credential and flashing a confident smile, her blonde waves styled in loose layers with sunglasses perched on her head.

Another image showed her walking along the iconic speedway track, hands tucked into her pockets while wearing dark sunglasses that added a cool, polished finish.

She also shared a close-up in a blue-and-black racing suit under a shaded tent, palm trees visible in the background, blending motorsport energy with a touch of California sunshine.

Alongside the post, McNamara reflected on last season’s highlights and hinted at a “wheel-y big surprise,” signaling that her passion for IndyCar remained firmly in the fast lane.
