Race cars made in NZ

Craig Greenwood is one of the best examples of someone who turned his passion into a business. He is also one of New Zealand’s most prolific racing car builders. Craig got into motor racing in the early 1990s, progressing from competitive cart racing to Formula Vee (now Formula First). The class is based on a 1200 cc VW motor and uses a collection of stock parts to form a competitive car from the engine, transmission, front suspension, brakes and wheels built into a space frame. The body is fibreglass or carbon fibre. It’s a racing class that allows an enthusiast to build and maintain his own car. Craig bought his first car but soon decided to build his own, working nights and weekends in a cramped single garage with little more than an oxy-acetylene welder, a hacksaw and a hand-held drill. “I wasn’t all that successful at first. Of 18 starts I made, I only finished four,” says Craig. “I realised that just knowing how to weld a chassis wasn’t enough, so I started to read about designing and building race cars.”

The body is fibreglass or carbon fibre. It’s a racing class that allows an enthusiast to build and maintain their own car. Craig bought his first car but soon decided to build his own, working nights and weekends in a cramped single garage with little more than an oxy-acetylene welder, a hacksaw and a hand-held drill.
“I wasn’t all that successful at first. Of 18 starts I made, I only finished four,” says Craig.
“I realised that just knowing how to weld a chassis wasn’t enough, so I started to read about designing and building race cars.”

The cars are driven via chain drive. This is similar to the locked diff common on race cars but allows for a very efficient transfer of power and less weight

Competitive
The cars got better, and he started becoming competitive. He realised it was more productive to build multiple cars and race them as a team. By 1993, with three cars, Greenwood started a scholarship system to find other drivers for his team. He was by now becoming competitive in the class. Before long, he had a team of six and was one of the biggest racing teams in the competition.
Craig went on to win the New Zealand Formula Vee Championship in 1997, and his team won in 1998 and 1999. Craig has built 23 Formula Firsts and developed a reputation for building quick and reliable cars, most of which are still racing.
By 1999, Craig had come up with a new design. Based on the Formula First series and with the knowledge earned from running his own team, he knew the drawbacks in the current design.

Motorcycle engine
“I realised I could build a car from a space frame and a motorcycle engine. I wanted to make it simple. The car needed to have easy access to replace or work on the motor, it needed to have easily replaceable parts, and above all, it needed to look and sound like a racing car. So we designed the body to look like a ’99 Ferrari.”
Craig wanted to go beyond simply owning the team, he started a new series—Formula Challenge. With that, he also pioneered the “arrive-and-drive” concept, where drivers could lease cars or simply rent the car for the race. All the cars were set up to be identical; the only variable should be the skill of the driver. This was intended to be a driver’s championship. He also ran a scholarship program to encourage new talent.
By 2002, the series had won recognition on TV with a winter series. The series ran to 2005.
Formula Challenge Racing now concentrates on providing individuals with the thrill of piloting a car that looks, sounds and handles like the real thing. It has a base at Taupo raceway but is also available at Hampton Downs and now at Rua Puna. They run 12 open-wheeler Formula Challenge cars and nine Vs, both Ford and Holden, to cater to all tastes.
The Challenge car has changed little; the power plant is a Suzuki GSXR 1100 cc motorcycle engine. The car sports wings, spoilers and a demountable nose section which has a safety element. In any impact, the nose section helps to absorb damage without distorting the chassis or suspension.
The suspension is hard in typical race-car style, and the steering is positive and responsive. The sequential five-speed gearbox is controlled with two buttons on a demountable steering wheel.
The car generates an impressive 150 brake horsepower with a top speed of 230 km/h. It is capable of 0-100 km/h in 3.8 secs. It can generate a force of nearly 2Gs on corners, and at a maximum of only 40 mm off the ground, the driver has a sense that the speed is electrifying.
Before heading off for a few laps, drivers see a video of a track drive. The cars are linked to a datalogger so the team can analyse each lap with the drivers to highlight good and bad practices to help drivers fine tune their skills.

Woodwork: getting started (2)

20 November 2025

A home workshop is a special place and will function much better if you are able to plan how it is set out. My first workshop was in a single garage which was also the home of a very old Austin 7. As I bought machines, things became a little tricky. It was not that motivating on a winter’s evening, knowing I had to shift the Austin and re-arrange the workshop before I started. Our architect’s major renovation to our home included the redevelopment of my workshop area and from a single garage to a 9 m x 6 m workshop was a massive leap forward, even if it is shared with an MG.

The Stude-Maker
Studebaker marketed their groundbreaking 1950 Aero-Nose models as “luxury for everyman.” A young Trevor Halstead thought this was a bit of him, so he began purchasing Studebakers in the early 1970s. The fact that the Champion model he chose was $50 less than the Ford he really wanted did play a small role in that life-changing decision. As they say, the rest is history.
“To the man on the street, they became known as bullet noses, and while they proved to be Studebaker’s best-selling model in 1950, those aero-lines did not age so well, and by 1952, the company reverted to a more conventional front end.
Fast forward a couple of decades into another hemisphere, and a one-man Studebaker ‘Next Look’ revival was about to begin, in the workshop of Studebaker devotee and custom-builder, Trev Halstead. This time, though, those vintage lines would take on wild and offbeat shapes.

Woodwork: getting started – part one

13 November 2025

Not be too many weeks pass before someone asks me how to get started in woodworking as a hobby. I have had a life-long interest in making or building things but only in the last 20-plus years has my woodworking become dominant. Most people contemplating something in the woodworking area say they have had previous exposure to the craft, but often that was just a brief introduction during their school days.
Perhaps the biggest decision is first to determine that you want to start making something out of wood. Once under way, you will probably move in a particular direction that interests you.
One of the best places to start is at a woodworking hobby class at a local school or polytechnic.
