Marcos was a British sports car manufacturer. The name derives from the surnames of founders Jem Marsh and Frank Costin.


Marcos was founded in Dolgellau, North Wales, in 1959 by Jem Marsh and Frank Costin. Costin had earlier worked on the De Havilland Mosquito fighter-bombers and from there he got the idea to use plywood for the chassis. The company moved to a converted mill in Bradford on Avon, Wiltshire in 1963 and in 1971 to a £125,000 purpose-built factory at nearby Westbury.

Problems with exporting cars to the USA and the move to the expensive new premises led to financial troubles, and in 1971 Marcos went out of business. In July 1971 it was reported that the Rob Walker Group of Companies, a principal dealer, had acquired the stocks and assets and established a new company, Marcos Ltd.[1] The new owners said production would continue, albeit, at least in the short term, only for the UK market,[1] but it is not clear whether any additional cars were built. Although Marcos dealers in the UK had been heavily discounting new cars since the end of 1970, and Motor magazine reported at the time of the collapse that the company's stock of 35 unsold cars in the USA had to be "liquidated",[1] there may have been a substantial stock of new cars still looking for buyers.

One Saturday in June 1972, what was described as "a cash jumble sale of Marcos bits – prototype and shop soiled components, benches, tools..." took place at what could now be characterized as the "old Marcos Cars factory" at Westbury.[2] The sale was occasioned by the company's reorganisation and move to a smaller factory.[2]

Jem Marsh stayed in the car business, and bought back the rights to the Marcos name in 1976. In 1981 the brand was relaunched with the Marcos V6 Coupé, which was sold in kit form.

Marcos went bankrupt again in 2000. Canadian entrepreneur Tony Stelliga bought the company, and revived production in 2002. Race car production was relocated to the Netherlands while road car production moved to Kenilworth, Warwickshire, England. By 2005 most of the designers from near-to-bankrupt TVR had joined the company.

On 9 October 2007 it was again announced that Marcos would cease production and go into voluntary liquidation.[3][4]

PredecessorMarcos GT

The first car, the Xylon, which had gullwing doors and a windscreen in four panels, was nicknamed the "Ugly Duckling". A total of nine, aimed at 750 Motor Club events, were built in 1959 and 1960.

For production the body was made less radical but initially retained the gullwing doors. It was powered by a choice of Ford engines varying from 997 cc to 1498 cc and had Standard 10 and Triumph Herald steering and suspension components. 39 were made up to 1963.

In 1961 brothers Dennis Adams and Peter Adams started working with Marcos and introduced several changes to the original design. The Marcos Luton Gullwing and the Spyder were introduced in November 1961. This design was again reworked, becoming the Marcos Fastback GT, which was displayed at the London Racing Car Show in 1963. The chassis was fabricated from laminated 3 mm thin sheets of marine plywood, giving the cars a strong monocoque and low weight (the GT was internationally homologated with 475 kg), so they performed well in sportscar competition. Most early Marcos models competed in national and international events.

In 1964 the Marcos 1800 GT was introduced. Originally it used the 4-cylinder Volvo 1800 cc unit with overdrive gearbox and De Dion rear axle but in 1966 this changed to Ford engines of 1500 cc, 1600 cc and 1650 cc and a coil-sprung live rear axle, with another change In 1969 to the Ford Essex V4 engine from the Ford Corsair and Capri Mk1. In 1969 the plywood chassis was replaced by steel, which shortened production time and allowed use of more powerful 6-cylinder engines, with a choice of 140 bhp (104 kW; 142 PS), 3-litre Ford Essex V6 engine (UK), 140 bhp (104 kW; 142 PS), 3-litre Volvo straight 6 or more rarely the Triumph 2.5-litre straight 6.

The GT had a wheelbase of 1,956 millimetres (77.0 in) and a height of 1,092 millimetres (43.0 in), and weighed 914 kilograms (2,015 lb). The Ford V6 version achieved over 120 mph (190 km/h) on test and the Volvo-engined model was not far behind it, but the heavy cast-iron engines increased nose-heaviness in comparison to the 4-cylinder variants.

Cars for the North Americas market had Volvo in-line 6 cyl 3 Ltr engines coupled to Borg-Warner automatic transmissions, tubular steel space frames, a higher ride height and no headlight covers, in order to get US road certification. Delays and problems, together with the development costs of the Mantis, led the company to close its doors for the first time.

Mini Marcos[edit]

The front-wheel drive Mini Marcos, designed by Malcolm Newell, was introduced in 1965. With a fibreglass monocoque body, Mini subframes and suspension, and a wheelbase of 80 inches (2,000 mm), it was powered by a transversely mounted Mini A-series engine driving the front wheels. A French-entered example came 15th and last in the 1966 Le Mans race, the only British car to finish.

When Marcos stopped making the car in about 1975, another company produced updated versions as the Midas. Cars were also made under licence in South Africa, Australia and Ireland.

Revived in 1991 for the Japanese market, production continued until 1995. A total of over 1300 Mini Marcos cars have been sold in kit form and as complete cars.

After the demise of Marcos Sales Limited, the Mini Marcos moulds were acquired by Marcos Heritage Spares, who relaunched the car in 2005 as the Marcos Heritage Mk. VI and Mk. VI GT.

Marcos Mantis[edit]

Mantis XP in Goodwood Festival of Speed 2010.

In 1968 came the first Mantis, the Mantis XP. A racing car designed for the sportscar-prototype class, it was powered by a mid-mounted BRM-Repco V8. Like earlier Marcos cars it used a plywood monocoque chassis, albeit different from that of the GT. Only one car was made, and its only race was the 1968 1000 km event at Spa, where it retired with electrical problems in heavy rain. Originally Marcos intended to race it in the 1968 Le Mans, but that was postponed from June to September, and by then the car was in America, fitted with a Buick V8 engine (from which the Rover V8 engine was derived).

A full restoration of the XP was completed in 2008. Now based in America, it has visited the UK for the Marcos 50th anniversary celebrations and the Goodwood Festival of speed.

1971 Marcos Mantis M70

The next Mantis, the 4-seater M70, was launched in 1970 and had a fuel-injected 2.5-litre Triumph TR6 six-cylinder injected engine mated to a 4-speed gearbox. The promotional brochure says the styling "gives high all round visibility", and "a low centre of gravity together with an extremely wide track ensures superb roadholding. The luxurious interior seats four in comfort, and the boot, with a capacity of 10 cubic feet, makes the Mantis ideal for the man who is going places and wants to travel in style."

32 were sold before the company went into liquidation in 1972. Autotune acquired the moulds and produced a few more cars in the mid-1980s as the "Autotune Mirage".

Marcos Returns[edit]

Jem Marsh resurrected the Marcos brand in 1981, offering the previous GT cars as kits. Engine options included Ford's 3.0 Essex V6, 2.8 Cologne V6, 1600 Crossflow, 2.0 Pinto and 2.0 V4, plus Triumph's 2.0 and 2.5 straight six. About 130 kits were sold up to 1989.

Marcos Mantula, Spyder and Martina[edit]

1990 Marcos Mantula

In 1983 the Marcos Mantula was introduced, externally very similar to the old GT, but now powered by a 3.5-litre Rover V8 with a 5-speed gearbox. This alloy engine weighed less than the previous six-cylinder cast-iron units, reducing overall weight to about 900 kg and making the car competitive against other Rover-powered sports cars such as TVR and Morgan. The engine evolved into the Rover Vitesse Efi engine, and later Mantulas were fitted with the 3.9 Efi. In 1986 the model was made available as a convertible, the Marcos Spyder, which would outsell the coupés in later production. 1989 saw the introduction of independent rear suspension, together with the Ford Sierra's 7" differential and disk brakes. The improved suspension allowed a full-width boot and the relocation of the battery and heater/air conditioning. 170 coupés and 119 Spyders were produced.

Launched in 1991, the Marcos Martina was externally very similar to the Mantula, but with flared front wheel arches. It used the Ford Cortina's 2-litre four-cylinder engine, steering and suspension, and approximately 80 were produced. Originally available as kits or factory-built, the cars were all factory-built from 1992. Production of the Mantula and Martina ceased in 1993.

Marcos Mantara & LM200GTRS,400,500,600[edit]

In 1992 Marcos left the kit car business and launched the Marcos Mantara that was sold through dealers in limited numbers. The main difference between the Mantara and the Mantula was the adoption of McPherson strut front suspension in place of the Triumph suspension, which in turn resulted in a wider front track, different bonnet, and flared front arches. The Mantara was powered as standard by a 3.9-litre Rover V8 or a 4.6 as an optional extra. For a return to GT racing, a range of modified Mantaras was also produced in the LM (Le Mans) versions. In order to qualify as a production vehicle, road going cars were also made. Several version of the LM were made such as the LM400 (with a Rover 3.9-litre engine), LM500 (Rover 5-litre) and LM600 (with 6-litre Chevrolet small-block V8). Only 30 road-going LM cars were ever built, and of these only one was a road-going LM600.

Marcos Mantis and GTS[edit]

In 1997 the Mantis name was re-used on a 2-seater coupé or convertible road car based on the LM series powered by a Ford Cobra V8 and capable of 170 mph (270 km/h). Due to the use of the new Cobra Engine the bonnet of the Mantis was significantly remodelled from the previous LM range (that used the Rover V8). The engine produced 370 bhp (276 kW; 375 PS). It cost £42000. In 1999 a 500 bhp (373 kW; 507 PS) supercharged version was announced, capable of 0-60 mph in 3.7 seconds. 18 road going cars were produced in total. A race variant was created and used in GT racing, as well as Marcos' own single type Mantis Challenge.

The Marcos GTS was a version of the new Mantis, but powered by 2-litre Rover engines. The top version was the 200 bhp (149 kW; 203 PS) turbo version. The only one LM200GTRS was ordered in 1997 from Mr. Stavros Galanakis and delivered in 1998 in Greece as a present to his son, George St. Galanakis and he customized it and modify it solving the serious Engineering problems[citation needed].

Marcos Mantaray[edit]

In 1998 the GTS evolved into the Marcos Mantaray, but now with 4.0 and 4.6 Rover V8 as well as the 2-litre Rovers. Only 11 were made with the 4.0-litre, and seven with the 4.6-litre engine. In fact only 17 were finished; the 18th was sold in chassis/body-only form[citation needed].

Marcos Marcasite[edit]

In 2002, after a break in production caused by bankruptcy, a new company was launched to manufacture the Marcasite TS250 with a 2.5-litre 175 bhp (130 kW; 177 PS) Ford V6 followed in 2003 by the 5-litre Rover V8-powered TS500.

Marcos TSO[edit]

The Marcos TSO was launched in 2004 with a Chevrolet V8 engine in either 350 bhp (261 kW; 355 PS) or 400 bhp (298 kW; 406 PS) versions. The car's components were CAD designed in England and its chassis engineering was completed by Prodrive.

Also in 2004, the 5.7-litre Chevrolet Corvette (LS1) V8 TSO GT was announced, but solely for the Australian market. It was joined in 2005 by the GT2 for the European market.

In 2006 Marcos announced the TSO GTC, a modified version of the current TSO with a racing suspension, racing brakes and a rear diffuser. The car continues on with its Chevrolet-sourced 420 bhp (310 kW) V8, but there was also a 462 bhp (345 kW) Performance Pack available as well. With the extra power from the Performance Pack the TSO GTC accelerated to 60 mph (97 km/h) in 4.1 seconds and to 100 mph (160 km/h) in 8.5 seconds. With the bigger 340 mm (13 in) AP Racing brakes, the TSO GTC delivered a 0-100-0 time of 12.9 seconds, and the extra power allowed it to accelerate from 50 to 70 mph (110 km/h) in just 2.1 seconds. Its top speed was over 185 mph (298 km/h).

Only about 7 cars were produced before the company went into liquidation in October 2007.

Marcos Racing History[edit]

Wooden Wonders[edit]

Marcos started out with race cars, with the first Xylon cars being built specifically for the 750 motor club races. Among the drivers were Jackie Stewart, Bill Moss, John Sutton, Jack Gates, John Mitchell and Jackie Oliver, as well as Jem Marsh. The young Jackie Stewart achieved 4 victories in 1961, while Bill Moss managed 9 victories in 10 starts (link). John Sutton won the 1961 Autosport Championship, and together with Jack Gates and John Mitchell, Marcos won the team prize.

Marcos Luton Gullwing Nürburg classic in 2007

When the car went into production as the Luton Gullwing many examples were bought for racing. In 1962 Stephen Minoprio was the Autosport 1000cc GT Champion in his Gullwing - setting 7 lap records in the process.

The Gullwing in turn evolved into the GT Fastback, also known as the 'Breadvan'. All 18 fastbacks made in 1963 went into racing, and like the Xylon and Gullwing they were FIA homologated in the GT category. However, without the gull wing doors the fastback's were awkward to get in and out of. Drivers included Jackie Oliver, Terry Sanger, and Derek Bell, and Jem Marsh of course. The sales brochure for the Fastback included options for 5 speed gearbox (Hewland), dry sump, 997cc (84 to88 bhp) and 1148cc (102 to 104 bhp) full race engines, light alloy bellhousing, 72 litre fuel tank (for endurance racing), light weight alloy oil cooler, perspex windscreen (saving 15 lbs).

The successor Marcos coupé road cars were popular track/day cars, and several were raced in the BARC and BRSCC Modsports championships, including Jonathan Palmer taking the 1977 Modsport championship in a V6 (link). Mark Hales also successfully raced a 1967 wooden chassis V6 in the Modsports class. The 1800 Volvo engined cars are accepted for historic racing under FIA Appendix K, where they are very competitive, and there are still wooden chassis Ford-engined cars being raced. The fact that the wooden chassis can take the stresses of racing for so many years shows what a successful design it was.

Mini Marcos[edit]

The Mini Marcos is also a very successful car on the race track. It made its debut at a rain soaked Castle Combe race track on 25 September 1965. Driven by Geoff Mabbs, it lapped all but one car to win the BRSCC race by 81 seconds at an average of 76 mph.

In 1966 a French Mini Marcos (with Marcos support [1]) was the only British car to complete the Le Mans 24 hour race. For the 1967 Le Mans, Marcos entered their own Mini-Marcos (drivers were Jem Marsh and Chris Lawrence). The car failed to finish due to an oil pump failure - however it was clocked at 141 mph on the Mulsanne Straight in the April test. The same car was more successful in the Kyalami 9 hour race in Nov 1967, when Jem Marsh and Brian Raubenheimer finished 15th, it appeared again in the 1968 race but did not finish.

Mini Marcos cars were raced widely [2], especially as a budget endurance race car, but also in local championships in many countries including Modsports in the UK. Mini-Marcos was also the chosen car for the "First Ladies International Race Team" (FLIRT), which competed at events such as the Nurburgring 1000 km race in May 1967, where they retired, the Grand Premo del Mugello in July 1967, coming 37th, and the Nurburgring 500 km race in September 1967 where two cars were fielded with Jackie Bond-Smith coming in 21st and 4th in class, and Joey Cook retiring.

XP Prototype[edit]

The XP prototype was intended for the 1968 Le Mans. Raced at Spa as a shakedown test, it was one of many cars that retired with electrical problems in heavy rain. This proved to be its only race. Le Mans was postponed that year and the XP went to America.

Second Generation Race Cars[edit]

After the company's resurrection in 1981 the emphasis was on road cars, although price lists for the early V8 cars included a competition specification for "circuit racing, hill climbs and sprints". Competition options include FIA-approved roll-over bar, limited-slip differential, rose-jointed suspension and full harnesses.

In October 1993 Marcos unveiled its new competition car and announced a return to GT racing, including Le Mans. Based on the Mantara, the cars were designated LM400, LM500 and LM600. After some successes in the British GT championship in 1994, Marcos won it in 1995, 1996 and 2000. Two cars also competed at Le Mans in 1995. Both suffered electrical faults, one retiring and the other (driven by David Leslie, François Migault, and Jem Marsh's son Chris) finishing second to last, having completed 114 laps fewer than the winning McLaren F1 GTR as its electrical problem stranded it on the Mulsanne straight for two hours soon after the start.

Mantis Challenge Race Cars

1998 saw the launch of the Dunlop-sponsored Mantis Challenge, a one-make race series for the coupé version of the Mantis road car with a dry-sump version of its 4.6 litre quad-cam Ford Modular V8 engine. Complete with FIA roll-cage the cars weighed 950 kg. Entries were few in 1998, and the cars were accepted for the Prvilege GT series as GT2, and the French GT series as GT3, winning one of the races in France. In 1999 the field was stronger, and the Dutch Mantis Challenge was also strong, and some races combined both. The 1999 UK series was won by Edward Horner, and the Dutch series by Robert Knook.[6]

38 Mantis Challenge cars were built, but the series did not continue beyond 1999, after the GT Championship introduced the GT3 class. Many are still raced, including in the British Endurance Championship (Britcar), and at least one has been converted for road use.

LM600, 2011 Dutch Supercar Challenge

In 2000, the Marcos racing business was sold to longtime GT sponsor Eurotech, a Dutch engineering firm. By that time, all Marcos racing cars and road car chassis were built in Holland, with road car assembly completed in Westbury by a much-reduced staff.

An LM600 driven by Cor Euser competed in the Dutch Supercar Challenge and won the GT Championship in 2002 and 2004, and again in 2009, the 50th anniversary of the founding of Marcos.
