Almost two decades of the Yokohama World Time Attack Challenge (WTAC) are now behind us, and I’ve spent a solid 15 years watching the event grow from inside the fence at Sydney Motorsport Park, Australia.
Over that time, time attack has evolved from fields full of heavily tuned street cars into one with an ever-increasing number of prototype-esque reinterpretations, showcasing some of the wildest aero concepts, massive power, and clever engineering. WTAC, mirroring this transformation, has grown and evolved into its own niche. Every year, the rulebook gets pushed a little further. Lap times drop, expectations shift, and what it takes to be properly competitive becomes increasingly intense.
The thrill isn’t just the racing; it’s waiting to see what comes next. Watching teams find another way to shave tenths off a lap, and drivers somehow make the whole increasingly ridiculous package work. But an arrowhead can only get so sharp. Keep refining it, and eventually there’s not much room left at the pointy end.
WTAC’s main contenders don’t really need long introductions or another rundown of their development stories – we know those cars and what they can do. So this year, I looked away from the pointy end of the paddock and focussed on unfamiliar cars in some of the restricted classes. Cars that reminded me of where this whole time attack thing came from.
Winning the event outright is now a monumental undertaking, so starting with a proven chassis and building on the years of existing development makes perfect sense. But what if winning isn’t the whole point? What if you just want to see how fast you can make something you already love? That question led me to share with you three of my favorite cars from the 2026 event.
The No Idea Club Nissan Micra
The Nissan Micra (aka March) is about as far removed from the traditional motorsport winner’s circle as you can get, which is exactly why Sean Austin’s K11 is so damn good. I have no idea why, but watching it made me feel happy.
Sean’s ‘No Idea Club’ Micra stopped the clock at 1:45.111, placing 24th in WTAC’s Haltech Clubsprint class. That might not sound especially heroic buried in a results table, but standing trackside and watching this tiny red shopping trolley tear around Sydney Motorsport Park, looking and sounding completely furious, was something else. And this wasn’t just another World Time Attack Challenge outing. WTAC 2026 was seemingly the Micra’s final hurrah before retirement.
The car has been a long-running project shared between Sean and his dad, evolving over many years into something very far removed from Nissan’s original intentions. Sadly, Sean’s father has since passed away, and with that chapter of the project now closed, Sean feels it’s time to park the Micra too.
It’ll head back to the shed rather than disappear completely. Maybe one day, when Sean’s own children reach the right age, there’ll be reason to drag it back out and start tinkering again. I hope so too, because beneath all the sentimentality is still an absolutely ridiculous little car that’s enormous fun. A turbocharged SR20VET engine, front-wheel drive, and approximately 550hp, all squeezed into something with the wheelbase and general proportions of a roller skate, ensures that.
No trophies. No unlimited-budget development programme. Just a father-and-son project taken about as far as Sean wanted to take it. For a final lap of the dance floor, it was a pretty cool way to leave.
The Zuboo Racing Suzuki Swift
Then there was Daniel Harding and Zuboo Racing’s Suzuki Swift.
Mk2/3 Swift GTis carry a particular nostalgia in Australia. Tiny, light and built during an era when 100hp in a hatchback weighing roughly the same as a well-fed Labrador was considered perfectly adequate. Zuboo’s version has obviously wandered a long way from the sales brochure.
This particular Swift has already proven itself in other forms of motorsport, and at WTAC, the little Suzuki was entered in the MoTec Pro Open class. That meant sharing a results sheet with Rob Nguyen’s Dream Project Nissan Silvia S15, Nathan Morcom’s GAS Mitsubishi Lancer Evo, Bailey Sweeny’s Hyundai TCR i30N and Kazuyoshi Okamura’s Yashio Factory S15.
Daniel posted a best lap of 1:37.348 to finish fifth in class, which, wonderfully, placed the Swift ahead of the Yashio car, which recorded a 1:38.221.
Context is king, because no one expects an old Suzuki Swift to challenge the pinnacle of modern time attack machinery. But nobody standing against the fence needed an explanation for why it was so cool, either. It was fast, it was different, and it looked like an absolute riot out there. I saw the reaction on the faces in the crowd: this car made people happy.
At this point, the Zuboo Racing Swift seems determined to work its way through the motorsport catalogue one discipline at a time. Circuit racing? Tick. Drag racing? Tick. Time attack? Pass me a pen. I’m starting to wonder if the team will eventually throw a set of gravel tyres on it and point the Suzuki down a rally stage. Given how it’s going, I wouldn’t bet against it.
The KILLAH510 Datsun 1600
Last but not least, we have Dylan Auton’s KILLAH510. Calling this Datsun 1600 (510) an underdog becomes a little dishonest once you look under the skin.
At its heart sits a stroked 6.0-litre Nissan VK56DE V8, based on the engines Kelly Racing developed for the Nissan Altima Supercars programme here in Australia, and producing somewhere around 800hp. There’s an Albins sequential transaxle, Supercar-derived suspension hardware, serious carbon-ceramic brakes and a huge Andrew Brilliant-designed aero package producing enough downforce to slightly interfere with the Earth’s rotation.
Technically, as it stands, it’s less Datsun 1600 and more a prototype wearing a Datsun hat and t-shirt. But the reason it exists is wonderfully simple.
Auton grew up with Datsun 1600s. His father first bought one new in 1969 and then rallied them. Dylan’s first car was a 1600 and, by his own count, he’s owned at least eight examples. I guess you could say Datsun 1600s make Dylan happy. So when he decided to spend the best part of a decade building his ultimate time attack vision, choosing anything other than a Datsun 1600 was never an option.
Supercars driver – and World Time Attack Challenge regular – Tim Slade put the finished result to work. At its first WTAC, KILLAH510 recorded a 1:23.304, finishing third in MoTeC Pro Open, less than 1.5 seconds off the class-winning lap time posted by Rob Nguyen (1:22.005).
That’s not really underdog pace anymore, and maybe that’s the point.
The Yokohama World Time Attack Challenge needs monsters at the front; they push the sport forward, reset the clocks, and give everybody else a number to chase. But the event also needs Micras, Swifts, and slightly unhinged Datsuns. Cars chosen because somebody cared about them long before they were competitive. Cars built to answer questions nobody else was asking. Cars where success might mean a trophy, a personal best, one last hurrah, or simply pulling back into pit lane having gone faster than yesterday.
The pointy end of WTAC shows us where time attack is going. These cars remind us why it started.
