The Mitsubishi Debonair first generation was a larger luxury car first built in the mid-1960s, that stayed in production for 22 years.

History

It is a 2-liter to 3.5-liter class 4 -door sedan and the first competing model is Toyota Crown, Nissan Cedric, Prince Gloria, Isuzu Berel, Mazda Luce. Honda Legend. The 1st generation had a fully standardized body and front bench seat that held up to 6 people in total, and the 2nd and 3rd generations used front - wheel drive, so the interior was still spacious and practical. Also, as a chauffeur-driven option. Debuted at the 1963 Motor Show, and started production in 1964. Since then, for 22 years until the model change in 1986, it continued to be produced without any changes in the basic design and design, so from the latter half of the production period onwards. It became famous by the name of the only sedan type passenger car made in Japan for private use that was manufactured for a longer period than this is the first model of Toyota Century (1967-1997).

The Debonair was initially powered by a 1991 cc straight-six, with double carburettor and double exhaust 105 hp at 5000 / min and allowed a top speed of 155 km / h. In the seventies, a 1994 cc in-line six-cylinder was used, which drove the Debonair with 132 hp up to 180 km / h. Thanks to a number of smaller retouches (model series Debonair I to IV) over the course of time, the debonair remained so popular with its Japanese buyers that it was built in its original form for 22 years. As the types A30,31,32 and 33 in total 21,703 units were built.

In the early 1960s, Mitsubishi Heavy Industries planned to produce passenger cars of a class comparable to domestic competitors' 2,000cc-class passenger cars. Initially, the introduction of European cars was also considered. For this reason, Mitsubishi changed its policy to in-house development. The structure was a monocoque body with independent front wheel wishbones, rear wheel semi-elliptical leaf rigid and rear wheel drive. The styling was done by former General Motors designer Hans S. Bletzner. Based on the design of a large American passenger car in the 1960s, it has a strong style with edges on both sides of the bonnet and tail and a wide front grille the front suspension was independent, wishbones, coil springs, anti-roll bar and telescopic dampers at the rear rigid axle, semi-elliptic leaf-springs andtelescopic dampers. 

In May 1965, a "power specification" equipped with an automatic transmission (AT), front electric separate seats, power windows, and power steering was added the fuel tank capacity: 11 imp gal, 13.2 US gal, 50 1and a  carrying capacity: 1,058 lb. 480 kg . In December 1967, the instrument panel was changed to a shock-absorbing type with some changes By April 1969, the specifications were changed to include a front disc brake as standard equipment, and at the same time, the wheels were changed to 14 inches. Elimination of the rear rocket tail.

In September 1970, the model was changed to A31 by changing the installed engine at the same time as minor changes. Become a "Debonair Executive". The original in- line 6-cylinder KE64 type 1,991cc OHV was changed to the newly developed 6G34 in-line 6-cylinder 1,994cc SOHC, powering up to 130 horsepower. Due to cost constraints due to small production volumes, these were designed with two more cylinders than the existing 4-cylinder engine, and were produced on a limited basis using 4-cylinder engine production.

In October 1973, it moved to the late model with a major minor change. Abolition of the triangular window of the front door, change of tail lamp design (abolition of L tail), change of front blinker position.

In June 1976, it underwent another minor change and became the "Debonair Executive SE" (C-A32), with a 2.6-liter engine and number 3. Radial tires and electric remote-controlled Talbot-type fender mirrors are standard equipment, and the optional air conditioner changes from a trunk built-in cooler to a heater built-in type. Eliminate manual transmission vehicles. Production of the conventional 6-cylinder engine (6G34, 1,994cc SOHC), which was subject to stringent conditions due to cost reductions and exhaust gas regulations after the oil crisis, was discontinued, and an in- line 4-cylinder SOHC engine that complies with the 1976 exhaust gas regulations. This engine was generally called 2,600cc, and was produced with this large-displacement 4-cylinder until the end.

PERFORMANCE 2,555 cc
max power (JIS): 120 hp at 5.000 rpm
max torque (JIS): 152 1b tt, 21 kg m at 3,000 rpm

In April 1978, the model changed to E-A33 to comply with the 1978 exhaust gas regulations. In June 1979, it became compliant with the 1979 noise regulation with partial changes. The exterior was only changed in colouring, but the seat shape was changed in the interior, and the seat material was also changed from jacquard to velour. An electronic tuner radio with a rear-seat radio control function that can be operated from the rear seats is adopted. A safety device called an anti-skid brake equivalent to ABS was set as a manufacturer option.

By 1982, the emblem on the front grill was changed from "2600" to "MMC" as part of a change, and the "MCA-JET" emblem on the trunk lid was abolished. In addition to a column shift manual transmission, a 3-speed AT was also available. The 2,600cc in-line 4-engine vehicle in the final stage is set only for AT. For the AT body, the long- selling " BW-35 " 3-speed AT from Borg Warner, a major transmission manufacturer in the United States, was consistently used from the initial model to the final model.

As it was the flagship of Mitsubishi Motors, it was frequently used as a car for executives in each company of the Mitsubishi group, but because it had only a 6-cylinder engine. In May of the following year, a high-end grade called a power specification was quickly introduced. The demand for taxis, which had been emphasized, was not expected, and the development of sales bases was delayed, so the company lost the competition for market share. In addition, companies (especially those involved in large non-Mitsubishi affiliated companies) who disliked that image shunned them. Furthermore, in the 1970s, the basic design and design gradually became noticeable, and as a result, the actual situation was that it hardly sold to general users.
