The Morgan Plus 8 is a sports car built by British car makers Morgan from 1968 to 2004 and put back into production in revised form in 2012. Its instant and enduring popularity has been credited with saving the company and keeping the company famous during the 36 years of its manufacture. Among Morgan enthusiasts, it is deeply associated with Peter Morgan, the owner-chairman behind its design.
The development of the Plus 8 was led by Maurice Owen, an engineer taken on specifically for the role. The Plus 8 prototype was based on a modified chassis from the Plus 4, altered to accept the Rover alloy block 215 cu in (3.5 l) V8, purchased from GM-Buick in 1967. Plus 4's Moss gearbox was carried over and the Salisbury 7HA axle was uprated with a limited-slip differential. The chassis was developed in stages to accommodate gearbox changes in 1973 and 1976, the body widened in 1976 to accommodate the widened chassis and the wings widened to accommodate larger tyres to handle the increasing power and trend for lower profile and wider tyres. The original 1968 Plus 8 was 57 inches (1,400 mm) wide and the last was 64 inches (1,600 mm) (with an optional "widebody" at 67 inches (1,700 mm)) For several years in the 1960s the Plus Eight was the fastest-accelerating UK production car.
To mark the 35th year of production of its Plus 8, MMC released a commemorative 'Anniversary Edition' in 2003.
Following the discontinuation of the Rover V8, production of Plus 8 ended in 2004. A revised Plus 8, powered by a 4.8-liter BMW V8 engine, was introduced in 2012.
In 2014 Morgan announced a Limited Edition run of 60 Plus 8 'Speedster' models. This limited run forwent the traditional roof in favour of a small fly screen and hidden roll bars behind the front seats. Pitched as an entry level Plus 8 model they went on sale for £69,999.
The original Plus 8 engines were Rover V8s that became available when fitted to the P5B saloon. Morgan was actually the first of a succession of sports car makers- including the likes of TVR and Marcos- to use the engine.
The prototype Plus 8 (identifiable by two small bonnet bulges near the centre bonnet hinge) used a Rover V8 engine and the Plus 8 was launched in 1968 using Rover's production engine, itself a re-engineered version of the Buick/Oldsmobile 215 motor (renamed the 3.5 L by Rover) with a compression of 10.5:1 fueled by two SU HS6 carburettors. The high 10.5:1 CR was only usable because 5* (101 octane) petrol was then still available. By 1973, the Rover 3500 saloon was available with a manual 4 speed gearbox and this engine/gearbox configuration was adopted by Morgan although the compression dropped to 9.25:1 with a resulting drop in power. With the adoption of an improved version of the engine developed for the Rover SD1 in 1977, compression increased to 9.35:1 and power increased slightly. After 1981 the engine was fueled by two Stromberg CD175 carburettors, .
At the end of 1983, the company offered an EFI version using a Bosch L-Jetronic based system. With the added power (204 bhp (152 kW; 207 PS)) and low weight, the Plus 8 was, according to the magazine road tests of the day, able to best a Porsche up to 90 mph (140 km/h). In 1990 a 3.9 L version of the engine was fitted and that used the Lucas 14CUX fuel injection system.
In 1996, the Rover 4.6 L engine became an option, still using the Lucas fuel injection system. From 2000, all Morgan Plus 8s were fueled by the GEMS system as used on the Range Rover P38a between 1994 and 1999.
On the 2012 Geneva Motor Show, Morgan introduced a new edition of the Plus 8 roadster, powered by a 4.8L BMW V8-Engine. At the same show, Morgan also introduced an electric version of the Plus 8 roadster - called the Plus E - which is powered by a Zytek 70 kW (94 bhp) 300Nm electric motor.
United States sales
For almost two decades during the 1950s and 1960s, North America took the greater bulk of Morgan production. Popularity in the UK and Europe had greatly fallen during that era. The era ended with the advent of the strong emission and structural laws. Luckily, the failure of the modern looking +4+ and the arrival of the powerful Plus 8 rekindled interest in the home market in the whole line.
In the US, a way was found to keep importing Morgans after 1974. From 1974 to 1992, all imported Morgans (of which 98% were Plus 8s) to the United States were converted by independent dealers, especially Bill Fink, to run on propane as fuel to pass the U.S. emissions regulations.
When the Rover Group re-certified their V-8 engine for use in the Range Rover SUV sold in the U.S., Morgan made a gasoline-powered +8 available with the same engine in the same tune and with the same anti-emission devices. As safety regulations continue to change, Morgan was again challenged in 2006 to meet the new structural requirements announced by the NHTSA in 2000. A request for an exemption to the law on airbags was refused and the importation of traditional (classic) Morgans ceased.
