FactRootes fitted the Minx a Smiths Easidrive, the first dual-clutch transmission ever put into production.
The Audax body of the Hillman Minx was designed by the Rootes Group, helped by the Raymond Loewy design organisation, which had been involved in the design of Studebaker coupés in 1953. Announced in May 1956, the car went through a succession of annual facelifts each given a series number, replacing the mark number used on previous Minxes: the Series I in 1956, the Series II in 1957, the Series III in 1958, the Series IIIA in 1959, the Series IIIB in 1960, the Series IIIC in 1961, the Series V in 1963 and the Series VI in 1965; there was no Series IV. Over the years the engine was increased in capacity from 1390 cc (in the Series I and II) to 1725 cc in the Series VI. A variety of manual transmissions, with column or floor change, and automatic transmissions were offered: the Series I and II used a Lockheed Manumatic two-pedal system, the Series III a Smiths Easidrive, the first production dual-clutch transmission, and the V/VI a Borg Warner; the Series VI was fitted with an all-synchromesh gearbox. A Series III deLuxe saloon with the 1494 cc engine tested by The Motor in 1958 had a top speed of 76.9 mph and could accelerate from 0–60 mph in 25.4 seconds.

Owning one
We don’t estimate running costs for a car like this. What it costs depends on its condition, its specialist and how it is driven, and an average would mislead.

It briefly served as senior sibling to Marquette, a GM companion brand cancelled after just one year.

Nissan hired former BMW engineers to help develop the 510's suspension, which is why period reviewers frequently compared its handling to the BMW 1600/2002.

A Trabant 601 won its class at the 1970 Monte Carlo Rally, with a second 601 right behind it in second.

The 600 was a stopgap: the P50's body over the 601's mechanicals, and for a while its estate was built alongside the new 601 saloon.

The G80 Sport brought a 370 PS twin-turbo 3.3 V6, a mesh grille and copper-tinted chrome with copper stitching to match.

The Vigor was sold only with a five-cylinder engine, an unusual configuration Honda used to fit a longer engine transversely under a short hood.

The GS/E coupe earned the nickname "German Charger" for its long hood, short deck stance borrowed from Detroit muscle cars.

This DeVille/Fleetwood was the first production car anywhere to mount its V8 sideways, Cadillac's front-drive gamble on the new C-body.
