| | Tourer Coachwork: Cross & Ellis |
During the close of the 1930's, Alvis introduced new models to their line-up that shared many similarities and carried over many of the design and mechanical features that had made the Speed 20 model so successful. The first of these new models sat atop a slightly lengthened chassis with the old 2.8 liter engine replaced by a 3.6 liter six-cylinder unit. Next was the 4.3 Litre which actually had a 4.4 liter engine. Both of these versions were popular with coachbuilders often being delivered as only a rolling chassis. The most popular of these new models was the Speed 25 which had the same chassis as the Speed 20 but powered by a 3.5-liter engine.
The three new models were produced from 1936 until the onset of World War II with only minor modifications occurring over that period. All three had ladder frames with hydraulic shock absorbers with the rear being independent. The drum brakes were adequate while the four-speed manual gearbox with synchromesh was considered technically advanced. In 1937 a brake servo was adapted to help the driver keep the vehicle under control at speeds.
Most of the Speed 25 vehicles were delivered to the customers as a complete car. A few received custom coach bodies and are very rare in modern times. During the production lifespan of the Alvis Speed 25 nearly 400 examples were produced. There were around 60 examples of the 3.5-Liter version produced while the large 4.3-Liter version had nearly 200 examples produced.
