AC 3000ME

The AC 3000ME is a mid-engined sports car originally sold by AC Cars. The two-door coupé debuted at the 1973 London Motor Show. Sales did not begin until 1979 and lasted until 1984. Rights to the 3000ME and tooling were transferred to a second company who managed to produce a small number of additional cars before going into receivership themselves in mid-1985. A third company acquired the rights to the car with plans to begin selling a revised version under a different name, but only a single prototype was ever produced.

History
Origin The AC 3000ME was based on a prototype called the Diablo built by the Bohanna Stables company and shown at the London Racing Car Show in 1972. Production goals were set at 40 cars per week. ==Technical features==
Technical features
Running gear The chassis of the 3000ME was a perimeter frame whose central tub was made of folded sheet steel with an integrated roll-over bar. Some reviews of the car call the central tub a monocoque. Subframes were fitted at the front and rear. Bodywork was made of glass-reinforced plastic (GRP). Weight distribution was 40/60 front/rear. The car's suspension comprised upper and lower A-arms with coil springs and telescopic shock-absorbers both front and rear. The configuration incorporated anti-dive/anti-squat geometry. The suspension arms and uprights were fabricated by AC. No anti-roll bars were fitted to production 3000MEs. The braking system used dual hydraulic circuits to activate a Girling caliper operating on an AC-made rotor at each wheel. Early tyres were 195/60VR-14 Pirellis, which later grew to 205/60VR-14 size mounted on wide alloy wheels from Wolfrace. Engine and transaxle The engine used in the car was the 3.0-litre Ford Essex V6. In the 3000ME this all-cast-iron OHV 60° V6 produced and . It was installed transversely in the car behind the seats. The transmission was a 5-speed manual that, like the engine, was installed transversely. The transmission was an AC design, using an aluminium case produced by AC and a gear-set from Hewland. The engine drove the transmission via a triplex chain supplied by Renold. The driver selected gears with a Ferrari-like gated gearchange. Other The 3000ME was equipped with electric windows, a sunshine roof panel, Pilkington Sundym laminated glass, an adjustable steering column, and a radio with a powered antenna. == Technical data ==
Variants
Ecosse Signature Former racing driver and Ford technical sales specialist John Parsons and Ecosse Technical Director Aubrey Woods purchased the assets of AC (Scotland) with plans to resume production of the 3000ME. By this time the name and intellectual property of the original AC Cars had been bought by Brian Angliss of Autokraft, so Parsons and Woods incorporated their company as the Ecosse Car Company Ltd., and renamed the car the Ecosse Signature. The company was based in Knebworth, Hertfordshire. The exterior of the Ecosse Signature was restyled by Peter Stevens. Working from the AC (Scotland) Mark II prototype, the Alfa V6 powertrain was removed and a turbocharged Fiat Twin Cam engine and transmission from the Fiat Croma were substituted. The revised Ecosse Signature was shown at the 1988 Birmingham Motor Show. While it garnered some interest, the company was unable to secure the £350,000 in financing needed to restart production, and the project went no further. The prototype was rediscovered in an abandoned industrial storage unit in 2017. In unrestored condition it was offered for sale for £8000. AC Ghia In July 1980 Ford of Europe chairman Bob Lutz and vice president Karl Ludvigsen were in Turin at Carrozzeria Ghia checking on some ongoing projects. Ghia's chief designer at the time was Filippo Sapino. Sapino mentioned that Ghia was looking for a mid-engined Ford platform as a base for some future studies, and the Ford-powered 3000ME came up. Ludvigsen, whose responsibilities included overseeing Ford's European motorsports programs, saw this as a possible replacement for the recently retired Mark II Escort rally car. Ludvigsen involved both Ford's directory of rallying Peter Ashcroft and Ford's chief designer Uwe Bahnsen and on 22 September circulated a memo indicating that the revised car would conform to the new 1982 Group B rules. AC provided Ghia with two cars, one completely assembled and one rolling chassis, on the condition that they would be able to display the car at the 1981 Geneva Motor Show. The complete 3000ME left Thames Ditton on 16 October and arrived in Turin 4 days later, leaving 4 months for the work to be completed. At long and under wide the resulting car, named the AC Ghia, was both shorter and narrower than the original 3000ME. At high it was one inch taller. The car featured exterior door handles hidden in the edge of the engine intake ducts. Small quarter lights were added. Deep-offset alloy wheels from Speedline mounted 225/50 VR15 Pirelli P6 tyres. When it appeared at Geneva, it garnered favourable reviews. By this time Ford's rally efforts had moved on to a turbocharged, rear-wheel drive Mk. III Escort, so the AC Ghia was no longer being considered for that role. Still, both Ford and AC were looking for ways to get the car into production. Ford's interest in the car may have been informed by the progress General Motors was making on their nascent P-car project. Internal discussions at Ford over July and August 1981 determined that AC's production capacity was not sufficient for them to supply Ford's North American sportscar project. AC was told that Ghia would sell them the prototype and the tooling for it at a "nominal price". A new engine would have to be found, as Ford was phasing out the Essex V6, although the Ford Cologne V6 in fuel-injected form would be a natural replacement. Ultimately neither Ford nor AC were able to muster sufficient resources to put the car into production. The prototype was auctioned off in 2002. Lincoln Quicksilver In 1983 Ghia released another show car built on the second, rolling 3000ME chassis supplied by AC. This car was called the Lincoln Quicksilver, and instead of being shorter than the 3000ME, the Quicksilver chassis was extended by over that of the original. The extra length allowed the car, which kept the 3000ME's mid-engine layout, to be a full four-door sedan, but one with a roofline that extended rearward over the engine compartment and ended abruptly. The aerodynamic shape of the car allowed it to record a drag coefficient (c_\mathrm d) of just 0.30. Some references report that the original Essex V6 was replaced by a Cologne V6, but was still mated to a 5-speed manual transaxle. The car remained on the show car circuit until 1986. It appears to have been sold at auction by Ford in 2002 for a price of $45,825 and remained in private collections after that. It was sold again at auction in January 2014. AC-Chrysler 2.2 Turbo A plan was mooted to sell a modified version of the AC 3000ME in the United States as a Shelby. In 1980 American partners Steve Hitter and Barry Gale started bringing De Tomaso Panteras into the US from the Belgian distributor though their company, Panteramerica. That same year Gale was in Belgium on a parts buying trip when Claude DuBois, the Pantera distributor who was also the AC distributor, gave him a ride in an AC 3000ME. Gale flew to England and negotiated an agreement for the US rights to the car with Derek Hurlock and ordered one car, less engine and transaxle. This car, chassis #161, arrived in the States in February 1981. After a failed overture to Chevrolet for a supply of the V6 and transaxle from the new Chevrolet Citation, the car was sent to the US workshops of Arkay Incorporated in Hawthorne California. Arkay was run by Kas Kastner, the Triumph Motor Company's former Competition Director for North America. Arkay did general automotive development work, and specialized in turbocharger conversions. Arkay did a full assessment of the Chevrolet V6 and discovered that the AC would need a new subframe to fit it. Ford offered a 1.6 L inline-four powertrain, but this was rejected as underpowered. Eventually a Buick V6 was installed, but after Arkay adapted the Buick engine to the Chevrolet transaxle, Buick pulled out of the project. While Panteramerica was looking for a suitable engine, the car was restyled by Bob Marianich. At this point the car was seen by Ray Geddes. Geddes had sold his Pantera parts company to Hitter and Gale, who had renamed it Panteramerica. Geddes was now working for Carroll Shelby, and when he saw the car in Kastner's shop he got Shelby involved. At this time Shelby was working with Chrysler, for whom Kastner had already done a turbocharger kit for their 2.2 L engine that was available through Chrysler's Direct Connection performance arm. Shelby met the partners at the SEMA show in Las Vegas and agreed to take on the project. Work continued at Arkay until Shelby's new Chrysler-Shelby High Performance Center in Santa Fe Springs on the eastern edge of Los Angeles was complete, after which the car was transferred there. Under the direction of project administrator and chief mechanic Steve Hope, development engineer Neil Hanneman and engineer Scott Harvey, first a naturally-aspirated 2.2 L Chrysler engine was installed, replaced later by a turbocharged G-24 engine and 5-speed transaxle. The car was renamed the Shelby ME 2.2 Turbo. The prototype went to Metalcrafters to have bodywork and paint completed, after which it was presented to Chrysler president Lee Iacocca. The company decided not to put the car into production, so the prototype became a test mule for Shelby until the Los Angeles facility was closed, after which Hitter and Gale picked the car up and put it into storage. The prototype survives. ==Motorsports==
Motorsports
Chassis 119 was progressively converted into a "Lightweight" special suitable for use in hill climbs and sprints. Much of the conversion work, which included first a single- then twin-turbo engine upgrades, was done by Robin Rew. The car was later returned to a road-legal state, but kept many of the performance upgrades. This car appeared on the cover of the September 1986 edition of Sports Car Monthly magazine. Chassis 156 was imported to Australia, where it was converted for rally use. Extensive work was done to prepare the car for racing, including adding an F.I.A.-compliant roll cage, and complete overhauls of both the suspension and engine. Consideration was also given to using the car on the Historic racing circuit. A special tube-frame car with a heavily modified 3000ME body was built for the Supersports series. This car is powered by a Cosworth BDA engine driving through a Hewland transaxle. It was featured in the February 1992 issue of Cars and Car Conversions magazine. ==References==
