The Sapphire 236 (1955–1957, 603 made) is identical in appearance to the 234 but uses the six-cylinder 2,310 cc engine previously installed in the Whitley 18 (2,309 cc, 70 mm bore, 100 mm stroke, pushrod OHV, 7.5:1 compression, single downdraught Stromberg carburettor, 85 bhp at 4500 rpm). A conventional manual gearbox was offered, but many were fitted with a Lockheed Manumatic "clutchless" transmission, overdrive being an option on either. With an 85 mph top speed it was intended as a quiet, flexible, easy-to-drive saloon. Wheelbase 111 in (2,819 mm), length 180 in (4,572 mm), width 68.5 in (1,734 mm).

The Star Sapphire's doors hinged at the front with their hinges hidden entirely — styling that looks ordinary now but was genuinely ahead of its time on a 1958 luxury saloon.

Armstrong Siddeley pitched the Sapphire 234 as a genuine 100 mph car for drivers who wanted real performance — only 803 were ever built.

Most buyers of the "baby" Sapphire 236 skipped the clutch pedal entirely, opting for a clutchless Manumatic gearbox over the conventional manual.

A twin-carburettor upgrade on the Armstrong Siddeley Sapphire 346 cost just £25 — and bumped output from 125 to 150 bhp, enough to clear 100 mph.
Rivals
Same body, same money, other badges — tap any card to flip.

Simca beat Fiat to market by three months with what was essentially Fiat's own Topolino design.

The Simca 1000 began at Fiat: Simca boss Henri Pigozzi picked one of six boxy clay models from Fiat's "Project 122".

The last Simca 1000 ever built, the 1978 Rallye 3, was also the rarest — just 1,000 were made in the model's final year, a quiet send-off for a car that had sold nearly two million.

To drum up buzz at launch, Simca briefly swapped 50 of its Paris taxi fleet's Ariane sedans for tiny new 1000s, making the little car a familiar sight on the capital's streets.

The PL 17's name is a sum: 5 fiscal horsepower, 6 seats, 6 litres per 100 km, kept a digit below the Citroën DS 19's.

The humble Tagora spawned a one-off concept, the Présidence, decked out with Connolly leather and electronics way ahead of 1981 — a built-in telephone, dictaphone, text-message receiver and a TV with VCR.

Talbot fed the Tagora's V6 old-fashioned triple carburettors instead of fuel injection — and the extra power briefly made it the most powerful French car on sale. Only 1,083 were ever built.

Switching the 96 from a two-stroke to a Ford V4 was such a closely guarded secret that Saab invented a fake company, Maskinverktyg AB, just to buy the new engine's parts without its own purchasing department finding out.
