The AC Greyhound (1959-1963) was a 2+2 version of the Ace and Aceca automobiles made by AC Cars of Thames Ditton, Surrey, England. The Greyhound, of which 83 examples were built, had a two-door, four-seater aluminium body, and inherited most of the technical components of the Ace and Aceca:
- ladder-frame chassis
- independent coil spring suspension front and rear. Unlike the Ace and Aceca the rear suspension used semi-trailing arms.
- 4-speed manual gearbox, overdrive optional
- rack and pinion steering;
- 11.75 in (298 mm) disc brake front, 11 in (279 mm) drum brake rear
Various straight-six engines were fitted:
- 1.991-litre AC Cars OHC (75 bhp @ 4500 rpm; 1000 kg)
- 1.971-litre Bristol 100D2 OHV, (125 bhp @ 5750 rpm; 1015 kg)
- 2.216-litre Bristol (105 bhp @ 4700 rpm; 1093 kg)
- 2.553-litre Ford Zephyr (up to 170 bhp @ 5500; 1040 kg)
Three Greyhounds were left-hand drive; the rest were right-hand drive.
A 2 litre Bristol engined car with overdrive tested by The Motor magazine in 1961 had a top speed of 110 mph (180 km/h) and could accelerate from 0-60 mph (97 km/h) in 11.4 seconds. A fuel consumption of 21.8 miles per imperial gallon (13.0 L/100 km; 18.2 mpg-US) was recorded. The test car cost £3185 including taxes.
