The Clement-Talbot or Talbot 25-50 featured a 4.5 liter four-cylinder side-valve engine which was considered new technology for the turn of the century. The 25-50 could prove its ability too. Percy Lambert recorded the fastest speed at Brooklands raceway in 1912 in a Talbot 25-50 at 109mph. The car was a worthy competitor to other race cars of the day, such as the Hispano-Suiza King Alfonso and the Vauxhall Prince Henry. The nickname the "invincible Talbot" was well deserved.
