The Ferrari 456 and 456M (Type F116 and F116M) is a front-engined grand tourer. The 456 was produced from 1992 until 2003. It was an overdue replacement for the defunct front-engined 412 as the company's V12 four seater. The updated 456M was replaced in 2004 by the 612 Scaglietti. It was the last Ferrari model to use pop-up headlamps. ==456== Pietro Camardella and Lorenzo Ramaciotti at Pininfarina designed the original 456 which was available in GT and (from 1996) GTA forms. The difference in name signifies the transmission: the former has a six-speed manual and the latter has a four-speed automatic developed in partnership with FF Developments, in Livonia, MI (which was later purchased by Ricardo Engineering in the UK). This was only the fourth automatic transmission ever offered by Ferrari. The 5.5 L (5474 cc) 65° V12 engine was derived from the Dino V6 rather than the more conventional 60° V12s used in the 412 and Daytona. It produced with 4 valves per cylinder and Bosch Motronic M2.7 engine management. It could push the 1690 kg car and four passengers to making it the world's fastest production four-seater. Acceleration to was just 5.2 seconds, with a 13.4 second quarter-mile time. At the time of its development it was the most powerful road car ever developed by Ferrari (aside from the F40). In 1996 engine was changed with Motronic M5.2 management and typed as F116C. The name 456 is derived from the fact that each cylinder displaces 456 cubic centimeters. This was the last Ferrari to use this naming convention. Despite its supercar performance, the 456 has a relatively unstressed engine, which has proven to be a very reliable unit. The chassis is a tubular steel spaceframe construction with a one-piece composite bonnet and body panels of aluminium. The body panels are welded to the chassis by using a special "sandwich filler" called ''feran'' that, when laid between, allows steel and aluminium to be welded. Approximately 3,289 of all versions were built. These consisted of the following versions: 456 GT: 1,548; 456 GTA: 403; 456M GT: 688; 456M GTA: 650. 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「Ferrari 456」の詳細全文を読む スポンサード リンク
