History of the Riley 16/4

Introduced in 1938, the Riley 16/4 represents the culmination of Riley’s pre-war development. Built in Coventry, this model is often referred to as the "Big 4" or "Blue Streak" due to its powerful 2.5-litre four-cylinder engine. The car was constructed on the Adelphi chassis, which provided the basis for its remarkable handling and adaptability. At its release, the 16/4 stood out thanks to its strong performance in both touring and competition, quickly becoming a mainstay in sporting circles of its era.

Model History

The Riley 16/4 succeeded earlier, smaller-capacity Riley models and marked a significant step up in performance before WWII. The "Big 4" engine signified the highlight of Riley's inline four-cylinder development. While postwar production at Riley shifted direction, the 16/4 remained one of the brand’s top pre-war achievements, often rebuilt or meticulously maintained by enthusiasts and often documented with restoration records.

Highly regarded for its balanced and smooth body lines, the car often features period-correct details like folding running boards—sometimes with hidden floor compartments—and tailored accessories including hoods and tonneau covers.
