The Plus 8 was introduced to the public at the 1968 Earls Court Motor Show. Fitted with the Buick derived Rover V8 of 3529 c.c. and producing 160 b.h.p at 5200 r.p.m. the car was a revelation. With a Moss Gear 4 speed box it could reach 125 m.p.h. and hit 0 to 60 m.p.h in 6.7 seconds. A performance test at MIRA's timing straights from a standing start gave 90 m.p.h in 14.5 seconds, just before the quarter mile post 15.1 seconds and 110 m.p.h. 10 seconds later at 25.7 seconds. Interestingly the 4.2 litre Jaguar E-type took 15.1 seconds to get to 90 m.p.h. under the same test. A motoring magazine wrote " If, as many still do, you think that more than 4.5 inch of front suspension travel is cissy, that a quickly erected top and winding windows are effete, and that beat-proof synchromesh on all gears is a sign of moral decay, then here is the car for you." It cost £1477. 18s. 4d and by comparison the Jaguar E-type Roadster was £2117.
