Factory Specifications
The following information is extracted from AC's
press release's dated March 1974 and 1979

The AC 3000ME is a mid engined, 2 door sports coupe
with a 3.0litre V6 engine and 5 speed gearbox located transversely
behind the driver/passenger compartment, permitting almost ideal
weight distribution and contributing to exceptional road handling
and stability at speed.
The
monocoque perimeter steel chassis with substantial bolt on front
and rear sub-frames provide a very stiff structure with considerable
protection to passenger and driver. Safety is further enhanced by
doors with double internal steel beams, burst proof latches and
hinges, a double bulkhead structure, substantial internal roll-over
bar, and collapsible steering column.
The chassis is built with longevity in mind. The
monocoque interior is sprayed with Volvoline Tectyl, type ML 309
AW, rust protective through special apertures which are plugged.
This compound seals welding seams and forms an internal coat on
the monocoque chassis hollow sections providing good rust protection.
The chassis is painted externally with an etching
chassis paint, as are all-metal tube chassis and suspension fabrications,
the finished car is finally undersealed. (If only it had worked)
The AC 4-wheel independent suspension is AC designed
with anti-squat and anti-dive geometry. It is entirely purpose built
by the company; none of it is obtained from other auto manufactures.
Front and rear suspension, up-rights employ SKF second generation
hub bearing units, a development of the sealed and lubricated-for-life
double row angular contact ball bearing and assembly.
AC
Cars were able to manufacture a great deal of the car at their two
motor division factories, including monocoque chassis, sub-frames,
suspension wishbones and uprights, window frames, body shells, aluminum
gearbox case, clutch housing and chain case assembly. Brake calipers
are Girling, using discs front and rear manufactured by AC.
The transverse gearbox with 5 forward speeds and
reverse is of AC design; assembly and all operations took place
in the AC workshops. The drive from the engine to gearbox is by
special Renold Triplex chain, via triple tooth sprockets all enclosed
in a separate oil case with special chain tensioner.
A stainless steel exhaust system from manifold to
tail pipe is standard, as are electric windows, sunshine roof, sun-dym
laminated windscreen and windows, radio and electric aerial, Woofrace
aluminum wheels with 7" rims, 205/60 VR 14 wet weather radial
tyres, Disc brakes all round with dual hydraulic system, steering
column adjustable fro rake and length. Through flow fresh air system
with adjustable panel eyeballs, and under bulkhead vents, pressure
fed by two speed electric fans extractor slots rear body work, twin
spot lights, oil cooler, dual smiths thermostatically controlled
engine cooling fans,
The car was available in a choice of 16 paint colours,
black or beige cloth seats and carpets. Leather seats were available
at extra cost.
