FactWhen this Alvis flagship debuted, the motoring press couldn't get over its face, describing it as having "a most imposing front with very large headlamps, fog and pass lights, and post horns."
The Alvis 4.3-litre (198 built, model years 1937 to 1940) and the Speed 25 were British luxury touring cars announced in August 1936 and made until 1940 by Alvis in Coventry, replacing the Speed 20 2.8-litre and 3.5-litre. Their new six-cylinder in-line engines had seven main bearings (against four in the Speed Twenty), the clutch, flywheel and crankshaft balanced together, a cast-iron head, aluminium pistons, three SU carburettors fed by two electric pumps and an efficient silenced induction system; the 4.3-litre's 4,387 cc (92 x 110 mm) engine gave 137 bhp at 3,600 rpm. Alvis made none of the bodies: cars were supplied as chassis and fitted by firms such as Cross & Ellis (standard tourer), Charlesworth (standard saloon and drophead), Vanden Plas, Lancefield and Offord; the heavy steel chassis had a substantial cross-brace, an all-synchro gearbox, independent front suspension and servo-assisted brakes, and at almost £1000 it was not cheap. Wheelbase 127 in (3,226 mm), length 191 in (4,900 mm), width 70 in (1,800 mm), kerb weight 4,144 lb (1,880 kg).
