Morgan established its reputation via competition such as winning the 1913 Cyclecar Grand Prix at Amiens in France, driven by W. G. McMinnies, with an average speed of 42 mph (68 km/h) for the 163 mi (262 km) distance. This became the basis for the 'Grand Prix' model of 1913 to 1926, from which evolved the 'Aero', and 'Sports' models. Morgan himself won the "very tough" ACU Six Days' Trial in 1913, in the sidecar class. The same year, the company entered the MCC reliability trial, which it continued to do until 1975.
Racing success led to demand the company proved unable to meet.
These models used air-cooled or liquid-cooled variations of motorcycle engines. The engine was placed ahead of the axis of the front wheels in a chassis made of steel tubes brazed into cast lugs.
After the First World War, the company introduced an easily changed rear wheel, which customers had been seeking for several years. The 1921 Popular, powered by an 8 hp (6.0 kW; 8.1 PS) JAP and bodied in poplar, sold for £150. It was a sales success, the price dropping to £128, and the name changing to Standard, by 1923, when a Blackburne engine was also available. The Grand Prix was priced £155, and the Family (with two notional child seats behind the front bench, setting a standard 2+2s would follow for generations) was £148 with air-cooled engine, or £158 with water-cooled engine. The Anzani-powered Aero was also available, for £148. MAG engines were also optional.
Morgan's racing efforts suffered a blow in 1924, when E. B. Ware's JAP-engined car rolled at the JCC 200 mi (320 km) at Brooklands; Ware was seriously hurt, leading to a ban on three-wheelers competing as cars.
Electric headlamps were made available in 1924, at an £8 cost.[30] The Popular, powered by a 976 cc (59.6 cu in) engine, sold for £110, the 1,098 cc (67 cu in) Aero for £148, and the one-seater £160.
Like motorcycles, Morgans had hand throttles, Bowden-wire control mechanisms, and drip lubrication.
Racing Morgans included Harold Beart's 1,096 cc (66.9 cu in) Blackburne-engined special, with 3.33:1 top gear and a 43 lb (20 kg) streamlined body, which covered 91.48 mi (147.22 km) in a one-hour trial at Brooklands, with a peak speed of over 100 mph (160 km/h).
In 1925, the Standard's price had dropped to £95, and the Aero £130, compared to £149 for an Austin Chummy.[31] Electric lighting by dynamo became standard that year.
Front-wheel brakes and electric start (a £10 option) became available in 1927, while the Standard's price fell to £89, complete with a double-thickness windscreen and "electric hooter". By year's end, the Standard was even cheaper, £85, while the new Super Sports debuted, with an overhead valve JAP 10/40 water-cooled vee-twin, priced £155. The 10/40 engine was also available in the Aero, at £132, while a more sedate air-cooled JAP-powered Aero went for £119. The Family was priced at £102 (air-cooled) or £112 (water-cooled). These new, lower prices persisted through 1928. They would be lower still in 1929: the Standard and Family at £87 10s, the Aero £110, and the Super Sports £145. In 1933, the Family was priced at only £80.
