The Austin-Healey 100-6 is a two-seat roadster that was produced by Austin-Healey from 1956 to 1959. A replacement for the Austin-Healey 100, it was followed by the Austin-Healey 3000. Together, the three models have become known as the Big Healeys. The 100-6 featured a 2 in (50.8 mm) longer wheelbase than the 100, a more powerful straight-six engine in place of its slightly larger inline-four, and added two occasional seats (which later became optional). The body lines were slightly streamlined, a smaller, wider radiator grille placed lower, an air scoop was added to the bonnet, and the windscreen fixed. The 100-6 was produced in two model designators, the 2+2 BN4 from 1956 onwards and the 2-seat BN6 in 1958-9.The cars used a tuned version of the BMC C-Series engine previously fitted to the Austin Westminster, initially producing 102 bhp (76 kW) and increased in 1957 to 117 hp (87 kW) by fitting a revised manifold and cylinder head. The previously standard overdrive unit was made optional. In late 1957 production was transferred from Longbridge to the MG plant at Abingdon. 14,436 100-6s were produced before production ended in 1959.
