Wankel – Driven To Write

A bogged down revolution.

Apart from its compactness, free-revving nature and modest number of parts, the Wankel engine is of course known for its smoothness. This is not the first trait that comes to mind when one thinks of Russia but, on the other hand, no Wankel engine has ever been averse to enjoying a drink.

Although Russia was a bit of a latecomer when it comes to the Wankel engine, it was, for a period of roughly twenty-five years, quite seriously involved with the concept, resulting in close to forty different rotary engines being developed within that timespan. Development of the rotary engine started in 1974 at VAZ, better known in the West as manufacturers of the Fiat 124-based Lada saloon and Niva 4WD off-roader. Unlike NSU, Citroën, General Motors and Mazda, the Russians’ reason for developing rotary engines was of a somewhat sinister nature: they were initially designed to Continue reading “Join the Wankel Party”

Spirited Away

More curiosities from Japan.

Japan is a country where traditional values are held in high regard, yet outright wackiness at times abounds, where the business-suited salaryman shares a seat on the subway with a flamboyantly made up cosplay girl dressed in a frilly maid costume and nobody bats an eyelid. Hence, it is an environment where even normally conservative manufacturers are not afraid to Continue reading “Spirited Away”

Rotary Survivor

Driven to Write profiles a refugee who made it in the new World.

During the early 1970s, it appeared as though Toyo Kogyo’s Mazda division had stolen something of a march on the auto industry. Alongside Germany’s NSU, Mazda invested heavily into wankel engine development and while Neckersulm’s all-in commitment saw them Continue reading “Rotary Survivor”

Sons of the Silent Age – (2)

Part two: We briefly take the wheel

As Steve fires up the NSU’s power unit, it quickly settles into its distinctive buzz-saw rotary whine. I ask him how often he uses it? “Not as often as I should – I have too many cars. I don’t use it in the winter, but this summer it’s done about 1500 miles.” Mileage incidentally, which includes a trip to the recent 50th anniversary commemorations in Suffolk, where over 30 Ro80s converged. Among the attendees was an owner from Stuttgart who Continue reading “Sons of the Silent Age – (2)”

Theme : Engines – France

Do French engines live up to that nation’s fine engineering heritage?

In Post War Europe, engines were restricted by reasonably arbitrary taxation classes. In Britain, the old ‘RAC Horsepower’ rating was based on an archaic formula that related to the bore only, not the stroke and didn’t actually refer directly to the output of the engine.

Despite it being abolished in the late 1940s, it meant that the longer stroke engine, with its relatively low rev limit, lived on far longer in much loved stalwarts such as the Jaguar XK and BMC A Series and it did stem the development of lighter, freer running engines.

Italy was less prescriptive and, although there were aberrations, like home market only 2 litre Ferraris and Alfas V6s, it allowed the development of the sweet engines found in the Alfas and Fiats of the 60s. The French tried to Continue reading “Theme : Engines – France”
