Production1911–1914
Recorded originUnited Kingdom
ClassTwo-seat sociable three-wheel cyclecar
Power9 hp
Larger Autotrix sociable tricar distinguished from the 4 HP by its more powerful JAP engine and chain final drive. Buyers could instead specify a 6 hp water-cooled Fafnir engine, a powertrain option within the same large chassis rather than an independently named model. Exact cylinder configuration, wheelbase, gearbox, braking, price and output remain unpreserved in accessible summaries. Autotrix was the road-vehicle badge; Brooklands identified Edmunds and Wadden's separate roadster and racing motorcycles.
