The Alvis Alvis 4.3-litre and 3.5 litre Alvis Speed 25 were a pair of luxury touring cars announced in August 1936 as a replacement for the Alvis Speed 20 2.8-litre and 3.5-litre. The Speed Twenty’s 2.5-litre, 2.8-litre or 3.5-litre engines with four main bearings were replaced in the 4.3-litre and 3.5-litre Speed Twenty-Five with a strengthened newly designed six-cylinder in-line unit now with seven main bearings. For the 3.5-litre version had an output of 110 PS with a top speed of almost 160 km/h (100 mph). The clutch, flywheel and crankshaft were balanced together, which minimised vibration. The cylinder head was of cast iron but the pistons were of aluminium. Two electric petrol pumps fed the three SU carburettors, which were protected by a substantial air filter Alvis did not make any of the bodies for the Speed 25. The cars were supplied in chassis form and firms such as Cross & Ellis (standard tourer) Charlesworth (standard saloon and Drop Head Coupé) as well as Vanden Plas, Lancefield, Offord and others would fit open touring or saloon car bodies. The car was built on a heavy steel chassis with a substantial cross brace. With all-synchro gearbox, independent front suspension and servo-assisted brakes. Fast reliable and beautiful the Speed 25 was also expensive at almost £1000 Minor improvements to both cars announced at the October 1938 Motor Show included a dual exhaust system said to quieten the engine and improve power output Diolch am 95,808,343 o olygfeydd anhygoel, mae pob un yn cael ei werthfawrogi'n fawr.
