MG Q-type Midget

The MG Q-Type Midget (sometimes referred to as the QA) was a racing car produced by the MG Car company in 1934. The chassis was based on the one used on the MG K3 but was narrower and used N-Type axles. The engine used the cylinder block from the P-type but with a special crankshaft to bring the capacity down to 746 cc by reducing the stroke from 83 mm (3.3 in) to 71 mm (2.8 in). A high pressure Zoller supercharger was fitted giving a boost to 2.5 atmospheres (1.8kg/cc) and allowing the engine to produce 113 bhp (84 kW) at 7200 rpm. A sprint version was also made with output increased to 146 bhp (109 kW) which at nearly 200 bhp (150 kW) per litre was the highest specific output of any engine in the world at the time.

Probably only eight were made (Michael Sedgwick states nine) as the car was expensive at £550-650 and the rigid axle chassis had difficulty in dealing with the power of the engine. The single seat version achieved a lap speed of 122 mph (196 km/h) at Brooklands race track driven by George Harvey-Noble and the two seater was capable of 120 mph (190 km/h).

MG K-type Magnette

The MG K-type Magnette was produced by the MG Car company from October 1932 to 1934.

Launched at the 1932 London Motor Show, the K-type replaced the F-Type Magna but having at first a slightly smaller capacity engine it took the name Magnette. The chassis was similar to the Magna but strengthened and had the track increased by 6 inches (150 mm) to 48 inches (1200 mm) and was available in two lengths with a wheelbase of either 94 inches (2388 mm) or 108 inches (2743 mm). The steering was modified with a patented divided track rod which was claimed to reduce kick back at the steering wheel. The brakes were cable operated with 13 inch (330 mm) drums made of "Electron", a light alloy, with shrunk in steel liners. Suspension by half elliptic springs and Hartford friction shock absorbers all round with rigid front and rear axles. Wire wheels with 4.75 x 19 tyres and centre lock fixing were used.

The engines were based on a Wolseley overhead camshaft design used first in the 1930 Wolseley Hornet and subsequently used by MG in the F-Type but subject to a major re-design. The stroke was reduced from 83 mm to 71 mm to reduce the capacity from 1272 cc to 1087 cc and a cross flow cylinder head fitted. Fitted at first with triple SU carburetors it produced 39 bhp (29 kW) at 5500 rpm. In early 1933 a modified version of the engine was announced that had improved valve timing and only two carburettors but the output was up at 41 bhp (31 kW). This engine was called the KB and the previous version, which continued in use, the KA. In late 1933 they were joined by the KD with a larger 1271 cc capacity by returning to the F-Type stroke of 83 mm but with the improved cylinder head and timing power was up to 48.5 bhp (36.2 kW). (The F-Type had only been rated at 37 bhp.) In addition there was the KC engine for the racing cars. This retained the 1087 cc capacity but with the aid of a supercharger power was up at 120 bhp (89 kW) at 6500 rpm.

Drive was to the rear wheels through either a four speed non-synchromesh gearbox or ENV made pre-selector type.

All the road cars were capable of reaching 75 mph (121 km/h).

K1

This was the original K having the long chassis and was first shown with the saloon body, KA engine and pre-selector gearbox all costing £445, quite expensive at the time. It was soon joined by a tourer with KB engine and manual gearbox. Later the saloon could also be had with KD engine and pre-selector.

54 K1s with KA engines, 74 with KB engines and 53 with KDs were made. Not many of the saloons were sold and surplus bodies/chassis were later fitted with MG "N" type engines and sold as the MG KN Magnette.

K2

The K2 was the open 2 seater and so had the shorter chassis. It had at first the KB engine and manual box but later cars could have the KD with pre-selector.

16 were made with KB engines and a further 4 with KD engines.



K3

The K3 was the racing variant and used the short chassis. The KC engine at first used a Powerplus supercharger replaced later by a Marshall made one. They were prominently mounted in front of the engine below the radiator. Pre-selector gearboxes were used. They were successfully raced in 1933, winning the 1100 cc class in the Mille Miglia and scoring an outright vistory in the Ulster RAC Tourist Trophy (TT) race where the car was driven by Tazio Nuvolari. Only 33 were made and as well as the works cars they could be bought for £795 but subsequently quite a few replicas have been made often from the K1 and K2 models.
