The Riley 2.6 replaced the Riley Pathfinder as the largest limousine model of the company.
The 2.6 had only one other grille, a different logo, and two-tone paint. They had a 6-cylinder in-line BMC C-Series engine with 2,639 cc displacement and 101 bhp (75 kW). The car had a top speed of 149 km/h.
The Riley 2.6 was an economic mistake and was scrapped in May 1959.
