AC Ace is a car which was produced by AC Cars of Thames Ditton, England, from 1953 to 1963. ==History== AC came back to the market after the Second World War with the staid 2-Litre range of cars in 1947, but it was with the Ace sports car of 1953 that the company really made its reputation in the post war years. Casting around for a replacement for the ageing 2-Litre, AC took up a design by John Tojeiro〔 that used a light ladder type tubular frame, all independent transverse leaf spring suspension, and an open two seater alloy body made using English wheeling machines, possibly inspired by the Ferrari Barchetta of the day. Early cars used AC's elderly two-litre overhead cam straight-six engine (first seen soon after the end of the First World War), which, according to a 1954 road test by ''Motor'' magazine, gave a top speed of and in 11.4 seconds and a fuel consumption of . It was hardly a sporting engine, however, and it was felt that something more modern and powerful was required to put the modern chassis to good use. Joining the Ace in 1954 was the Aceca hard top coupé, which had an early form of hatchback rear door but used the same basic timber framed alloy body. From 1956, there was the option of Bristol Cars' two-litre straight-six with 3 downdraught carburettors and slick four-speed gearbox. Top speed leapt to with in the nine second bracket. Overdrive was available from 1956 and front disc brakes were an option from 1957, although they were later standardised. In 1961 a new 2.6-litre () straight-six 'Ruddspeed' option was available, adapted by Ken Rudd from the unit used in the Ford Zephyr. It used three Weber or SU carburettors and either a 'Mays' or an iron cast head. This setup boosted the car's performance further, with some versions tuned to , providing a top speed of and in 8.1 seconds.〔(【引用サイトリンク】url=http://www.motorbase.com/vehicle/by-id/47/ )〕 However, it was not long before Carroll Shelby drew AC's attention to the Cobra, so only 37 of the 2.6 models were made.〔(【引用サイトリンク】url=http://www.classicandperformancecar.com/front_website/octane_interact/carspecs.php/?see=3206 )〕 These Ford engined models had a smaller grille which was carried over to the Cobra. With the engine set well back in the chassis, the Ace handled well and was successful in competition. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「AC Ace」の詳細全文を読む スポンサード リンク
