Ferrari 400

The Ferrari 400 and Ferrari 412 are front-engined 2+2 coupé cars from Italian manufacturer Ferrari and were available with the 5-speed all synchromesh or an optional 3-speed automatic transmission unit from General Motors. Their design was derived from the almost identical looking 365 GT4 2+2 (which itself was based on the famous Daytona). Production began in 1976, when Ferrari revealed its first car fitted with an automatic transmission - the 400 - at the Paris Motorshow of 1976. With the improved 412 introduced in 1985 it was phased out in 1989. Today, its sleek, Pininfarina-designed lines and relatively limited production numbers may give it potential as a future classic.
Although it may have been designed with Americans in mind, such as the automatic transmission and later emissions compliance, no version of the 400 series was officially imported to the USA. However, many of them are on American soil as gray imports.
The 400 Automatic or 400A used the General Motors Turbo-Hydramatic THM400 automatic transmission, whilst the 400 GT used a 5-speed all synchromesh transmission.
The engine, based on the Daytona's 4,390 cc (4.39 L; 268 cu in), was a 4,823 cc (4.823 L; 294.3 cu in) V12 producing 340 PS (250 kW); front mounted and driving the rear wheels, the traditional GT car layout allowed Ferrari to fit four seats into the stylish coupé.
400i & 400i GT The carburetors on the 400 were replaced with Bosch K-Jetronic fuel injection for 1979. As in the smaller 308i, power was down substantially, to 310 PS (228 kW), but emissions were much improved.
The 400 was improved for 1985 with an increase in displacement to 4,943 cc (4.943 L; 301.6 cu in) and a restoration of the original car's 340 PS (250 kW). ABS was offered for the first time on a Ferrari; the manual and automatic transmissions were both retained.
Production was stopped in 1989 with only the mid-engined Mondial offering 2+2 seating. The classic front-engine layout returned in 1992 with the 456.
