The **Talbot 105** was a high powered sports car developed by [Talbot](/source/Talbot_(automobile)) designer [Georges Roesch](/source/Georges_Roesch). It was famously fast, described by one authority as the fastest four-seater ever to race at [Brooklands](/source/Brooklands).[1]

## History

The 75 was derived from the earlier 14-45, named according to its fiscal and actual horsepower.[1] The six-cylinder engine displaced a volume of 1,666 cc[1] and was the basis for all Talbot engines until the [Rootes](/source/Rootes_Group) takeover in 1935.

The engine was repeatedly bored out further, giving rise to a succession of performance improvements. Throughout these developments, the exterior dimensions of the original 14-45 engine block remained the same although the 18-70 had an updated block with equally spaced bores. The later 105 had a different block again.

The 1930 [London Motor Show](/source/London_Motor_Show) saw the debut of the 18-70 model, bore and stroke both being increased to give an engine capacity increased to 2,276 cc.[1] In this form the car was later called simply the Talbot 70 or 75.[1] Higher compression ratios and a bigger Zenith carburettor resulted in an increase in power and the birth of the 90. Talbot's AO90s were highly successful in GP racing, coming third only to Speed 6 Bentleys in the 1931 Brooklands 500.

An increase in the engine capacity, still without any change to the exterior dimensions of the engine block, yielded a cylinder displacement of 2,969 cc for the iconic Talbot 105 model.[1] In 1931 four 105s were tuned to provide a reported 119 bhp, at 4,800 rpm.[1] In "Brooklands trim" further tuning and in increased compression ratio of 10:1 gave rise to a claimed 125 bhp.[1]

The Talbot acquired its fame on the racing circuits, featuring prominently at [Brooklands](/source/Brooklands), in the north-eastern suburbs of [Surrey](/source/Surrey). In 1932 Talbot pulled out of racing, but a major Talbot dealer named Warwick Wright successfully ran a team of three 105s that year, and other teams operated by dealers and enthusiasts continued to race the cars at least till 1938.[1]
