The Ferrari 456 and 456M (Type F116) are front-engine grand tourers which were produced by Ferrari from 1992 to 2003. The 456 was a replacement for the front-engine 412 as the company's V12-powered four seater. The updated 456M, which was the last Ferrari model to use pop-up headlamps, was replaced in 2004 by the 612 Scaglietti. Pietro Camardella designed the original 456 Grand Tourer at Pininfarina. It was available in GT and (from 1996) GTA models. 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.) The automatic transmission used in the 456 was the second and last conventional hydraulic automatic transmission with a torque converter to be offered by Ferrari. (The transmission found its latest use in the 400/412 series.) The 5.5 L (5,473.91 cc) 65° V12 engine was derived from the Dino V6 rather than the more conventional 60° V12s used in the 412 and Daytona. It is rated at 442 PS (325 kW; 436 hp), with 4 valves per cylinder and Bosch Motronic M2.7 engine management. Ferrari claims it could push the 1,690 kg (3,726 lb) car to a top speed of 309 km/h (192 mph), making it the world's second fastest production four-seater automobile behind the Porsche 959. Acceleration from 0-97 km/h (60 mph) takes 4.8 seconds, with a 13.3 second quarter-mile time. At the time of its development, it was the most powerful regular production road car ever developed by Ferrari. In 1996, the engine management system changed to Motronic M5.2 management and the engine with the updated system given the F116C code. (Source: Wikipedia.org, CC BY-SA)
