supercars legend
"...with Tabitha Ambrose, daughter of Marcus Ambrose, supercars legend and former NASCAR race winner."
“Supercars” is a big Australian race series. When they call someone a “legend,” it means they were really successful and well known in that racing world.
“Supercars” refers to Australia’s premier touring-car racing category, known for high-performance V8-powered machines and intense racing. Calling Marcus Ambrose a “supercars legend” frames him as a top figure in that series, not just a general motorsport competitor.
NASCAR
"...daughter of Marcus Ambrose, supercars legend and former NASCAR race winner."
NASCAR is a famous American racing league, mostly with stock cars. It’s a big deal to win or race well there.
NASCAR is a major American stock-car racing series, with races typically run on oval tracks. Mentioning Marcus Ambrose as a former NASCAR race winner highlights that he competed at the highest level in the U.S. as well as in Australia.
V8 supercars
"...his junior days in Europe conquering V8 supercars as we used to call it and it's challenging moments too..."
That phrase points to the Supercars racing cars that used V8 engines. It’s basically describing the kind of engine those race cars had.
“V8 Supercars” is the common name for Australia’s Supercars Championship era when the cars were powered by V8 engines. The transcript uses it as a shorthand for the category’s identity and engine character during Marcus Ambrose’s time.
test day
"Let's put you in a little pink go kart and so there we went, did a test day in a little pink go kart. Mega this is in America. No in Australia."
A test day is practice time on the track. You’re not racing for points—you’re learning the course and getting the car (or kart) set up so you can drive better.
A “test day” in motorsport is when drivers run sessions outside of a race to learn the track, dial in setup, and build confidence. For beginners, it’s often about getting comfortable with driving lines and basic race procedures.
go kart
"Let's put you in a little pink go kart and so there we went, did a test day in a little pink go kart. ... In Tassie. In Tassie. In Tassie. Kart club. Club yeah."
A go-kart is usually where racers start. It’s a small race car that helps you learn how to drive fast, brake, and take corners—often through a local kart club.
Go-karting is the common entry point for many racing drivers because it’s affordable, teaches fundamentals, and develops steering/braking habits. Kart clubs and test days are typical early steps before moving into cars.
kart club
"In Tassie? In Tassie. In Tassie. Kart club. Club yeah."
A kart club is an organized local group that runs karting events and provides access to tracks, schedules, and rules. For young drivers, clubs are often where you find coaching, practice days, and entry-level competition.
COVID really kind of messed us up
"[168.1s] then COVID really kind of messed us up just with the whole trajectory of everything obviously [172.1s] you're locked down, can't do much racing."
COVID made it harder to race and practice. Many events were paused, and people couldn’t get to tracks or work on cars like normal.
The pandemic disrupted motorsport schedules and training opportunities worldwide. Lockdowns and event cancellations meant fewer races, fewer track days, and limited access to teams and facilities.
sims
"[174.5s] Dad started building sims and so if I wasn't in the go kart I was on the sim, he had a motion [178.6s] sim which was really cool so the VR, the motion sim and yeah I just started loving it."
In motorsport, “sims” usually refers to racing simulators—software plus hardware that lets drivers practice virtually. They’re used to keep skills sharp when real-world racing is limited.
VR
"[178.6s] sim which was really cool so the VR, the motion sim and yeah I just started loving it. [183.9s] He and I might have had quite a few gin and tonics one night and he showed me that sim"
VR is a headset that makes the simulator feel more real. Instead of just watching a screen, it feels like you’re sitting in the car.
VR (virtual reality) headsets can make racing simulators more immersive by putting you “inside” the cockpit view. That immersion can improve spatial awareness and consistency during practice.
motion sim
"[178.6s] sim which was really cool so the VR, the motion sim and yeah I just started loving it. [183.9s] He and I might have had quite a few gin and tonics one night and he showed me that sim"
A motion sim is a simulator rig that moves like a real car would. It helps you feel what the car is doing, not just see it.
A motion sim uses actuators to physically move the seat/cockpit to mimic acceleration, braking, and cornering forces. That feedback helps drivers learn car behavior and improves realism compared with a static setup.
hauler
"[244.2s] then all of a sudden they wheel out, they bring out the hauler and they have the NASCAR [248.3s] come out and then Dad's in his race suit"
A hauler is the trailer/transport vehicle used to move a race car to and from events. Motorsport teams rely on haulers to protect the car and keep logistics organized.
race suit
"[248.3s] come out and then Dad's in his race suit and all the kids are kind of getting around it [252.0s] because there's such a big culture around NASCAR in America, it's huge"
A race suit is the special protective outfit drivers wear. It helps keep them safer in a crash.
A race suit is protective driver clothing designed to reduce injury risk and improve safety during racing. It’s typically used alongside other safety gear like helmets and harnesses.
700 plus horsepower
"I mean it's such a massive amount, more horsepower, 700 plus horsepower compared to the formula..."
Horsepower is how much power the engine makes. “700 plus” means the car is dramatically more powerful than the smaller race car she’s used to.
Horsepower is a measure of engine power, and “700 plus horsepower” indicates a very high-output race car. The comparison to Formula Ford highlights how much more power (and therefore speed and acceleration) Tabitha is stepping into.
Formula Ford
"700 plus horsepower compared to the formula for what the heck was that thing like... I think the Formula Ford has taught me a lot because it is such a light..."
Formula Ford is a stepping-stone type of race series. It’s usually lighter and less powerful, so you learn how to drive well rather than just rely on raw engine power.
Formula Ford is a lightweight, open-wheel junior racing category known for driver development and relatively modest power compared with top-tier series. Tabitha references it as her training ground, explaining that its light weight teaches car control even without big horsepower.
light car
"...but I think the Formula Ford has taught me a lot because it is such a light, I know it doesn't have the horsepower behind it but because it's such a light car it kind of gives the effect of having a lot of power"
A lighter race car is easier to change direction and speed. She’s saying that even with less power, the car feels lively because it’s light.
A “light car” changes how the vehicle responds to throttle, braking, and steering because there’s less mass to accelerate and slow down. Tabitha connects this to her Formula Ford experience, saying the lightness can create the sensation of having lots of power even when horsepower is lower.
throttle
"under your foot if that makes sense because in a relative sense because you can't just put the throttle on otherwise you know you'll lose the rear so just it has kind of the same quirks"
The throttle is the pedal that tells the engine how much power to make. In racing, if you press it too hard at the wrong time, the rear tires can lose grip and the car can spin.
In racing, the throttle is how you control engine power to the wheels. How you apply it matters because sudden throttle input can overwhelm traction and cause oversteer or loss of rear grip.
rear wheel drive
"for me it was Formula Ford just learning the craft, rear wheel drive, a lot different to the exel, front wheel drive"
Rear-wheel drive means the engine sends power to the back wheels. That can make the car feel different when you accelerate out of a turn—sometimes the back end wants to slide more.
Rear-wheel drive (RWD) sends power to the rear axle, which changes how the car accelerates and how it behaves at the limit. Compared with front-wheel drive, RWD often makes throttle-induced oversteer more noticeable in corner exits.
race team
"We ran the little race team last year and so I learnt a lot about what actually goes into running a race team."
A race team is more than just the driver. It’s the whole group that handles planning and support so the car can actually race.
A race team is the organized group that prepares the car and supports the driver(s) during events. Beyond driving, it includes logistics, budgeting, entries, and day-to-day coordination so the car can compete reliably.
logistics
"Yeah, so logistics, so I ended up being in charge of the logistics, so booking the accommodation, changing accommodation, like invoices, travel flights, that was a big one..."
In motorsport, logistics covers the practical planning needed to get people and equipment to events on time. That includes travel schedules, accommodations, and coordinating the timing around race weekends and time zones.
women in motorsport
"The great initiatives and there are many of them around women in motorsport are something that you are very giving and happy to be a part of, but I sense in you too, you are racer."
This is about helping more women get involved in racing. It can include training programs, support from teams, and opportunities that help women move up in motorsport.
“Women in motorsport” refers to efforts, programs, and initiatives aimed at increasing participation and visibility of women across racing. These can include driver development pathways, mentorship, sponsorship, and team support.
motorsport ladder
"As you take those next steps on the ladder, you need a calling card to be able to say, hey, I'm the, you know, whatever, my CV shows that I've won the Formula 4 championship and so on."
In racing, there’s usually a path you climb. You start in smaller series, then move up to bigger ones as you prove you can drive and win.
“Motorsport ladder” refers to the common progression system in racing, where drivers move up through increasingly competitive series. Each step is meant to build skills, results, and credibility so teams will take you seriously.
on track
"[1210.7s] Same with mum. [1212.0s] Mum's been telling me how to drive and what I should do on track. [1215.1s] She's been getting very vocal."
“On track” refers to driving or racing on a dedicated circuit rather than public roads. Track driving emphasizes consistent technique—lines, braking points, and throttle control—because there’s less margin for error.
racetrack
"And so it is it's a family thing for us at the racetrack like mum gets in and she does the catering and she helps out when she can."
A racetrack is where racing happens. It’s a special track built for cars to drive fast and compete safely, and people often spend the day watching or helping around the event.
A racetrack is the purpose-built venue where cars compete under controlled conditions. In motorsport, trackside roles (like watching from the pit or grandstands) are part of the culture and can influence how teams and drivers operate during events.
Repco
"Thanks to Repco. I mean, we got to do so many cool stuff and also showtime."
Repco is an Australian car-parts company that also supports racing. Here, they’re basically helping create a fun, sponsored experience around the event.
Repco is an Australian automotive parts and performance brand, closely associated with motorsport sponsorship and support. In this segment, Repco is mentioned as enabling the experience and providing “activation,” which is typical of race-week brand marketing.
Volkswagen Bus
"...t what they called it, but it's like this little bus and the little truck and it's got the stage and ..."
A Volkswagen Bus is a small van made to carry people. It’s shaped like a box and is often used for trips or transporting a group. The podcast mention likely refers to it as a “little bus” version of Volkswagen’s small vehicles.
The Volkswagen Bus is a classic light-duty van known for its boxy shape and its role as a people-mover—often used for family travel, camping, and small-group transport. In a podcast context, it may come up because it’s closely associated with the era when Volkswagen also offered related small commercial vehicles, making it a recognizable “little bus” concept. It’s discussed frequently because it’s both practical and instantly identifiable.
activation
"because it was just like, OK, this is, you know, the activation around that. Repco had so much activation around that start around that amazing ad"
“Activation” is marketing that happens at the event—like fun stuff a sponsor sets up to get fans involved. It’s more than just an ad; it’s an experience.
In motorsport marketing, “activation” means brand-led events and experiences designed to engage fans during race weekend. It often includes on-site promotions, appearances, and interactive activities tied to a sponsor’s messaging.
green screen
"they had this massive green screen, these floating trees that went around and then they had the bus"
A green screen is a filming trick where the background is replaced later with computer-made scenery. It helps productions show places or effects that would be hard or expensive to build for real.
A green screen is a production technique where a solid color background is replaced with digital scenery in post-production. In automotive or motorsport media, it’s commonly used to create track environments or stylized visuals without physically building the set.
MC capacity
"I got to work on that in an MC capacity. I love that your dad was the guest of honour that night."
“MC capacity” means she was the host for the event. She likely introduced people and helped run the schedule so everything flowed smoothly.
“MC capacity” means acting as the master of ceremonies—hosting the event, introducing speakers, and keeping the program moving. For motorsport nights and charity events, the MC role is often central to how the audience experiences the evening.
GT4 competition
"...can be a powerful tool with the big commitment that the family has made to GT4 competition in Australia. We'll release that next week."
GT4 is a type of race series for sports cars. The cars are based on models you could buy, but they’re set up for racing under rules meant to keep things affordable.
GT4 is a class of sports-car racing built around production-based cars with tighter cost controls than higher tiers. Teams typically run customer-spec cars with standardized rules, making it a common entry point for amateur-to-semi-pro drivers and families building a motorsport program.
500cc Grand Prix
"And our latest feature ep is with former 500cc Grand Prix bike winner Kevin McGee, two parts there, an hour and a quarter of conversation..."
The 500cc Grand Prix refers to the premier motorcycle racing class historically run with 500 cubic centimeter engines. It’s a major part of Grand Prix motorcycle history and is associated with top-level riders and high-risk racing.
