Mitsubishi Diamante

The Mitsubishi Diamante was a midsize luxury sedan produced by Mitsubishi Motors from 1990 to 2005. The car entered the U.S. market only in 1992, which was two years after its original launch. The car debuted at the Tokyo Motor Show in 1989 and went into production in Japan the following year. The name was derived from the Italian and Spanish word for ‘diamond’.

Mitsubishi Diamante Origins

The Mitsubishi Diamante was the second generation of the Mitsubishi Magna, and it replaced the wide-1983 Galant Sigma version of the Magna. The Diamante was not initially meant to be launched as a production model in Japan, and there were rumors of it being just a low-volume model. This was because of the taxation class system that was still in force in 1989. According to this system, cars that were wider than 1700 mm incurred a large tax penalty. As a result, most companies kept its cars within this width, but that was not the case for the Mitsubishi Diamante. In addition, Mitsubishi was renowned at the time for its luxury cars. The introduction of the Diamante was probably a response to the launch of the Honda Legend in 1986. Nevertheless, the taxation system ended in 1989, and the Mitsubishi Diamante became one of the few successful executive cars the same year.

About the Mitsubishi Diamante

The Mitsubishi Diamante was the company’s flagship sedan in the U.S. market. It was praised for its ride quality and quietness, although some models were a little noisy. The car was initially offered as a sedan and station wagon, which was one of its plus points in the U.S. market. However, the second generation of the Diamante, post-1997, did away with this feature. The Mitsubishi Diamante is still used to this day in several rental fleets.

Mitsubishi Diamante Features

The 2004 model was part of the redesigned second generation of the Mitsubishi Diamante. It was 4 inches longer than the previous generation, the interior was bigger, and the styling inside was crispier. The V-6 engine in the 2004 Mitsubishi Diamante had the displacement of a 3.5-liter engine with a power rating of 210 hp, which was bigger and more powerful than the previous generation. The station wagon was cancelled in the second generation. The wheelbase of the car remained unchanged, but the interior volume increased by 7.4 cubic feet from the first generation. The second generation Diamante was also 250 pounds lighter due to the liberal usage of aluminum parts.

The 2004 Mitsubishi Diamante came with standard features like dual-front airbags, although anti-lock brakes were an option. The car came with a four-speed automatic gearbox as standard. The gearbox could vary its gear shifts according to the driver’s style. Other standard features in the last Mitsubishi Diamante included power windows and mirrors, power locks, automatic climate control, and a security system.

Mitsubishi Diamante Evolution

The Mitsubishi Diamante went into production in 1990, but it entered the U.S. in 1992 as a replacement for the Mitsubishi Sigma. The car won the Japan Car of the Year award when it was first launched in 1990 and was available as a four-door sedan. The first generation of the Mitsubishi Diamante saw the release of three versions of the car. The first was a four-side window sedan that did not have rear-quarter windows; this version was only meant for the Japanese market.

In the United States, the Mitsubishi Diamante was available in three trim levels: ES, LS, and VR-X. All three levels were fitted with an automatic gearbox and a front-wheel drive. The ES used a 3.0-liter 12-valve SOHC V-6 engine that was also found in the Magna at the time. The station wagon version of the Mitsubishi Diamante ES also came with a 3.0-liter Y7 SOHC V-6 engine that delivered 158 hp at 5000 rpm. Standard equipment included driver’s airbags, central locking, power mirrors, and power windows. The Mitsubishi Diamante LS had the same features and engine and also included cruise control, alloy wheels, and ABS. The VR-X was the sportier version of the Mitsubishi Diamante.

The second generation Mitsubishi Diamante went into production in January 1995. It was released in the U.S. market in 1997 after a year’s gap in production. The design of the car was modified to improve headroom by a significant margin. The car was available in several engine types. The base engine was a 2.5-liter lean burn V-6; mid-level engine was a 3.0-liter version of the V-6, while the top-end models had a 3.5-liter MIVEC V-6 that delivered 260 hp of power and 239 lb-ft of torque.

The car was fitted with a five-speed automatic gearbox that included INVECS-II technology. The car received upgrades in 2002 and 2004, which would be the last model year for the Mitsubishi Diamante in the United States, although production continued for another year in other markets.
