1975 Suzuki RE5

1 November, 2024

Suzuki had high hopes for its RE5 Wankel-engined bike launched in 1975. It had started looking at the Wankel engine in the mid-60s and bought the licence to the concept in 1970.
Apparently all of the big four Japanese makers experimented with the design, Yamaha even showing a rotary-engined bike at a motor show in 1972. But Suzuki was the only one of the big four to go into production. Like many others at the time, Suzuki believed that the light, compact, free-revving Wankel design would consign piston engines — with their complex, multiple, whirring valves and pistons, which (can you believe it?) had to reverse direction all the time — to history.

ROTARY CHIC

6 September, 2024

Kerry Bowman readily describes himself as a dyed-in-the-wool Citroën fan and a keen Citroën Car Club member. His Auckland home holds some of the chic French cars and many parts. He has also owned a number of examples of the marque as daily drivers, but he now drives a Birotor GS. They are rare, even in France, and this is a car which was not supposed to see the light of day outside France’s borders, yet somehow this one escaped the buyback to be one of the few survivors out in the world.
It’s a special car Kerry first saw while overseas in the ’70s, indulging an interest sparked early on by his father’s keenness for Citroëns back home in Tauranga. He was keen to see one ‘in the flesh’.
“I got interested in this Birotor when I bought a GS in Paris in 1972. I got in contact with Citroën Cars in Slough, and they got me an invitation to the Earls Court Motor Show where they had the first Birotor prototype on display. I said to a guy on the stand, ‘I’d like one of these,’ and he said I wouldn’t be allowed to get one. Citroën were building them for their own market to test them, and they were only left-hand drive.”

Smooth operator – ’74 Mazda RX-4

23 August, 2023

Cory Wilson’s Dunedin-based Retro Automotive offers servicing and a comprehensive restoration service for Mazda rotaries. As reported in the February 2021 issue of New Zealand Classic Car magazine, he joined forces with a Dunedin businessman to import a rare Mazda RX3-SP from Florida in the USA. That car and five others from Cory’s collection were, until recently, part of a display entitled “The Evolution of Japanese Cars” at Bill Richardson Transport World in Invercargill. One of them was this car: a 1974 Mazda RX-4 sedan.
“One of my customers rang me up out of the blue and asked me if I wanted to buy an RX-4,” says Cory. “I went around and had a wee nosy. The guy who was selling it had bought it when it was in its faded factory yellow, complete with the old supermarket battle wounds and stuff like that.”
The owner had it restored but it returned from the painters in a bright canary yellow colour, definitely not the factory colour.
