"Produced between 1961 and 1967, the Triumph TR4 combined a new, modern, and aggressive body design by famed Italian stylist, Giovanni Michelotti, with the basic chassis of the previous TR3A. The TR4 also improved passenger comfort with wind-up windows, face-level ventilation, and an optional hardtop. When equipped with the optional overdrive, the TR4 was good for a top speed of almost 110mph. Following on from the TR4, the new TR4A was phased in smoothly at the beginning of 1965 and introduced an all-new independent rear suspension system (IRS), which provided exceptional rear-wheel camber control with excellent wheel travel while softer springs improved the ride quality. Having six universal joints, three propshafts and two trailing arms, the system was appreciatively more expensive than the previous live axle arrangement (dealers in the US reacted uncomfortably to the new design on cost grounds; to appease them, Triumph actually built the TR4A in two forms, one with a live axle primarily for the US and the TR4A IRS for other markets where the price was less sensitive). The press was happy to see an all-independent car, and Triumph was pleased to be the first British car manufacturer to have all-independent suspensions under every car in their line-up. At the Sebring 12 Hours in 1966, ample proof of the validity of the IRS was provided when three IRS-equipped TR4As achieved a remarkable 1-2-3 class victory.
This very good 1966 Triumph TR4A IRS, with overdrive, was the subject to a complete restoration over three years between 2011 and 2013. The owner at that time changed the colour from blue to British Racing Green, fitted a Surrey top with a new canvas cover and fitted new black, piped in white seats. He kept the car for a further two years selling it to a lady in 2015 who in her ownership covered under 2000 miles. In 2020 it was purchased by a specialist hire company who supply vehicles to the film and television industry specifically to be the hero’s car in the both series of ‘Pennyworth’, due to be released in December 2020. Pennyworth explores the early the early life of DC Comics character Alfred Pennyworth before becoming Bruce Wayne (Batman) butler, a former British SAS soldier who formed his own security company in London in the 1960’s. This TR4A IRS is supplied with a V5 registration document, an MoT test certificate which expires in November 2021 and a file containing a Heritage certificate, part invoices from the restoration, old MoT certificates and some photographs of the rebuild. This is a very good example of the desirable TR4A IRS that has only covered 2000 miles since the restoration."
