Enthusiasts were disappointed that this was a detuned version of the 76 bhp (57 kW) at 5800 rpm Cooper 'S' engine, giving only 65 hp (48 kW) at 6000 rpm and 72 lb⋅ft (98 N⋅m) at 3000 rpm. The engine grew to 1275 cc using the development seen on the Mini-Cooper 'S'. The test car cost £689 including taxes on the UK market. A fuel consumption of 40.2 miles per imperial gallon (7.03 L/100 km 33.5 mpg ‑US) was recorded. Ī car with the 948 cc engine was tested by the British magazine The Motor in 1962 and had a top speed of 87.9 mph (141.5 km/h) and could accelerate from 0-60 mph (97 km/h) in 18.3 seconds. Production was 16,080 of the small-engined version and 9601 of the 1098. The doors had no external handles or locks and the windows were sliding Perspex side-screens. 13x4" Wire spoked wheels became available. In October 1962, the engine was increased to 1098 cc, raising the output to 56 hp (42 kW) at 5500 rpm and 62 lb⋅ft (84 N⋅m) at 3250 rpm, and disc brakes replaced the drums at the front. A hard top, heater, radio and luggage rack were available as factory-fitted extras. Brakes were 7-inch (178 mm) drums all round. The engine was a 948 cc A-Series with twin SU carburettors producing 46 hp (34 kW) at 5500 rpm and 53 lb⋅ft (72 N⋅m) at 3000 rpm. Mechanically the car was identical to its Austin-Healey counterpart, retaining the rear suspension using quarter-elliptic leaf springs and trailing arms from the 'frogeye'. The new Midget differed from the Sprite only in grille design, badging, improved interior trim, better instruments and added external polished trim to justify its higher price.

Many existing MG buyers turned to the Sprite to provide a modern low-cost sports car and so a badge-engineered MG version reusing the Midget name made sense. The original 'frogeye' Sprite had been introduced specifically to fill the gap in the market left by the end of production of the MG T-type Midget as its replacement, the MGA had been a significantly larger and more expensive car with greater performance. The first version, announced at the end of June 1961, was essentially a slightly more expensive badge-engineered version of the MkII Austin-Healey Sprite deluxe version.
