The Triumph Mayflower is a British four-seat 11⁄4-litre small luxury car noted for its razor-edge styling. It was built by the Standard Motor Company and sold by Standard's subsidiary, The Triumph Motor Company (1945). It was announced at the October 1949 British International Motor Show, but deliveries did not commence until the middle of 1950. One of the nine prototype Triumph Mayflower's, "JWK 612", was factory tested 5000 miles across Europe in 1950, they used the famous rooftop test track of Impéria Automobiles in Belgium. The Mayflower was manufactured from 1949 until 1953.
The Mayflower's "upscale small car" position did not find a ready market, and sales did not meet Standard's expectations. The company's next small car, the Standard Eight of 1953, was a basic 0.8-litre economy car.
The Mayflower was the first car with unitary construction to be manufactured either by Standard or by the Triumph company that existed before Standard bought its assets. The body was designed by Leslie Moore, chief body designer of Mulliners of Birmingham with input from Standard's Walter Belgrove. The body shells were built by Fisher and Ludlow at Castle Bromwich, Birmingham.
The Mayflower had traditional "razor edge" styling similar to that of the Triumph Renown, imitating the style then still used by Bentley and Rolls-Royce cars. Standard's managing director Sir John Black believed this would be especially appealing to the American market. One advantage of the car's upright styling was that it could seat four people in comfort despite its small size, although there were complaints about the rear seat being constrained by the rear axle and being too narrow as a result.
A Mayflower tested at Brooklands racing circuit, by British magazine The Motor in 1950 had a top speed of 62.9 mph (101.2 km/h) and could accelerate from 0–50 mph (80 km/h) in 26.6 seconds. A fuel consumption of 28.3 miles per imperial gallon (10.0 L/100 km; 23.6 mpg‑US) was recorded. The test car cost £505 including taxes.
The Mayflower had been an attempt to create a small car with an upmarket image, but it failed to meet its sales targets. Standard announced the Mayflower's replacement in a press release in early February 1952; the announcement further stated that the replacement would probably not be on sale until 1953. The Standard Eight, which replaced the Mayflower, had a basic specification and was aimed at a different type of buyer. From the ending of Mayflower production in 1953 there was no small saloon with the Triumph name available in the United Kingdom until the launch of the Triumph Herald in 1959. The Standard Ten saloon and Standard Companion estate were sold as Triumphs in the United States.
^"The Mayflower is an elegant little car with a 1250cc, four cylinder engine, three speed gearbox, and a full width, two-door saloon body with much the same knife-edge lines as the bigger Triumph saloon. The interior finish is in the same good taste as the external lines and the whole car is an attractive combination of the merits of modern design with the high quality looked for in British cars." - From Our Motoring Correspondent (28 September 1949).

Of course the Mayflower was just repeating ancient history, for like the 10/20 and so many Triumphs since, it strove to be a "quality light car," and yet remain, as Holbrook held it, "typically English."

Inside, the rear seat was uncomfortably cramped over the rear axle; I swear that after a journey of any length, if two passengers had occupied it they emerged with one buttock squared into a block, for the interior was knife-edged too.
