1977 Ferrari 400i

Ferrari introduced the 400GT at the Paris Salon in 1976 and was the last of Ferrari's carbureted V12 engine. This 4.8-liter, four-camshaft V12 engine was devoid of pollution controls and breathed through six twin-choke Weber DCOE carburetors, producing 340 horsepower and 347 foot-pounds of torque. The 2+2 seater used a self-leveling independent rear suspension, electric windows, power-assisted steering, and air conditioning.

The Ferrari 400 proceeded the 365GT4 2+2, introduced in 1972 at the Paris Salon. It wore conservative Pininfarina styling with a large glass area, a comfortable interior, and a tubular steel chassis based on the GTC/4, but lengthened by 200mm to 2700mm. The floor was fiberglass and the bodies were steel. The steering was servo-assisted and the brakes were four-wheel discs. The 24-valve engine used wet-sump lubrication, four overhead camshafts, and an alloy block and head. The five-speed all-synchromesh transmission was coupled directly to the engine with the driveshaft connecting it to the rear limited-slip differential. The 400 that followed added an optional GM THM400 three-speed automatic transmission.

While the 365 GT4 2+2 had been named for its '2+2' seating configuration, four overhead camshafts (GT4), and single cylinder displacement (365cc), the 400 represented the increased stroke size resulting in an overall displacement of 4.8 liters (400cc single-cylinder displacement). With the help of six 38 DCOE 110-111 Weber carburetors, the engine delivered 335 horsepower and could sprint from zero-to-sixty mph in 7.1 seconds.

The addition of an automatic transmission and the larger displacement engine was the most significant change to the 400, compared to the 365 GT4 2+2. The prior Rudge knock-off hubs and optional Borrani wire wheels were replaced by five-stud wheels. The prior triple taillight assembly was replaced by double circular taillights, a lip was added to the front spoiler, and the interior was revised.

Production of the 400 lasted from 1976 through 1979, with the bulk of customers selecting the automatic transmission, accounting for 355 sales compared to 147 of the manual.

To comply with growing emission standards, a Bosch K-Jetronic fuel injection system was added in 1979, decreasing power to 305 bhp but improving the emissions. An 'i' was added to the badge on the rear of the vehicle, signifying the fuel injection system. Production of the 400i lasted from 1979 to 1985.

Near the end of 1982, additional modifications were made to the engine with new camshaft profiles and exhaust headers, resulting in a slight increase in horsepower to 311 bhp. More significant changes were made to the interior, including new upholstery, different door panels, new electronic switchgear, and a new center console. The exterior received a narrower grille and the vents on the hood were switched from silver to body color. New wing mirrors that wore a small Ferrari shield were added. Lower profile Michelin TRX tires on metric-sized wheels were added.

Again, the automatic transmission option proved the most popular with 883 examples sold compared to 422 of the manual.

A further increase in engine displacement resulted in the introduction of the Ferrari 412 in 1985. With an increased bore of 1mm, displacement grew to 4,942cc, resulting in 412cc of single-cylinder displacement. Upon its demise in 1989, Ferrari was left without a classic front-engine grand tourer model until 1992, with the introduction of the 456.

The total production of the 365 GT4 2+2, 400, and 412 was 2,907 units. This was the company's longest-ever production series. While the use of an automatic transmission may suggest it was intended for the American market, no version was ever officially imported to North America. Enzo Ferrari believed that the 8-cylinder Ferrari was sufficient for the U.S. market with its 55 MPH national speed limit, safety regulations, and strict emission standards. The examples that did make it to these markets were done as grey imports.
