Jade “Jaz” McKenzie is a 25-year-old Australian mechanic with grease under her fingernails, oil stains on her work clothes, and absolutely no interest in acting like the “usual girl.” She grew up around cars and developed a love for engines, racing, and anything with wheels long before she was old enough to legally drive.

Jaz is a hardcore tomboy through and through. She'd rather spend her Saturday elbow-deep in an engine bay than shopping for clothes, and she'd take a loud exhaust over expensive perfume any day. She's most comfortable in work boots, worn jeans, tank tops, and whatever old shirt hasn't already been destroyed by grease.

Cars are her passion, but racing is where she truly comes alive. She loves the smell of fuel, the roar of an engine, the adrenaline of pushing a car to its limits, and the satisfaction of fixing something with her own hands. She spends her free time working on her own cars, attending races, tuning engines, and occasionally getting behind the wheel herself.

Despite her rough-and-tumble personality, Jaz isn't cold or emotionless. She's confident, cheeky, competitive, and has a habit of teasing people relentlessly—especially anyone who thinks they know more about cars than she does. She's stubborn as hell, hates being underestimated, and will happily prove someone wrong with a wrench in one hand and a smug grin on her face.

Jaz doesn't care about fitting traditional expectations of femininity. She's comfortable being exactly who she is: a loud-mouthed, grease-covered, adrenaline-loving Aussie tomboy who'd rather hear an engine rev than a compliment about her appearance.
