Background
Alvis was one of the great names of the British motor industry.
The Coventry firm always maintained a reputation for quality and a unique market niche: more dashing than any Armstrong-Siddeley or Rover; not as expensive or ostentatiously opulent as a Rolls-Royce or a Lagonda; less aggressively sporting than a Bentley or Aston Martin.
But always a thoroughbred - no borrowed engines or badge engineering with other marques.
Alvis were innovators, too. They introduced a front-wheel drive production car in 1928, six years before the Citroën Traction Avant. They offered the first all-syncromesh gearbox in 1933 and, later the same year, the first British car with independent front suspension.
'In the scheme of things there are cars, good cars and super cars. When a machine can be put into the last of these three categories and yet is not by any means in the highest-price class, considerable praise is due to the makers. The model in question is the latest Alvis 4.3-litre sports tourer.' – The Autocar, August 1938.
Pre-war development of the six-cylinder Alvis culminated in the announcement of the 4.3-Litre model in August 1936.
The 4.3-Litre was based on the 3.5-litre Speed Twenty Five introduced the previous year, and was powered by an enlarged version of Alvis' new seven-bearing, overhead-valve engine producing 137bhp on triple carburettors.
The cruciform-braced chassis featured the kind of advanced thinking long associated with the marque: independent front suspension and a four-speed, all-synchromesh gearbox, introduced on the preceding Speed Twenty, were retained with the additional refinements of driver-controlled Luvax hydraulic dampers and servo-assisted brakes.
Claimed to be the fastest un-supercharged saloon on the UK market, the Alvis 4.3-Litre was certainly one of the few pre-war saloons capable of a genuine 100mph.
Sturdily built and endowed with a generous wheelbase, the Alvis six attracted some of the finest examples of the pre-war coachbuilders' art, though the 4.3-Litre's chassis-only price of £750 meant that ownership was necessarily confined to wealthy connoisseurs.
A complete 4.3-Litre cost around £1,100, outstanding value for money given its specification and performance, comfortably undercutting rivals such as the V12 Lagonda and 4¼-Litre Bentley.
Despite this price advantage, only 198 cars had been delivered when the outbreak of World War 2 stopped production.
