History of the Mitsubishi Eclipse

A child of the Chrysler alliance

The Eclipse was developed for North America, where sales began in the autumn of 1989; Japanese sales of cars imported from Illinois started in 1990, and limited European sales followed in late 1991, at first only in Austria, Sweden and Switzerland. The first two generations were sold alongside the Eagle Talon, and the first generation also as the Plymouth Laser, all products of Diamond-Star Motors, the joint venture between Mitsubishi and Chrysler.

Mitsubishi says the car was named after an unbeaten 18th-century English racehorse that won 18 races in a row and then retired. In Japan the first two generations were sold through the Car Plaza chain.

First generation

The profile was low and sleek, with a bonnet line so low that it needed a bump to clear the engine’s cam cover. Cars built before the facelift had pop-up headlights, while the 1992 to 1994 models had exposed aerodynamic headlamps and more rounded sheet metal. Five trim levels were offered, all front-wheel drive except the GSX.

The entry Eclipse had a 92 hp 1.8-litre 8-valve 4G37 engine. The GS DOHC used a 135 hp 2.0-litre 16-valve 4G63, and a 150 hp naturally aspirated all-wheel-drive version was sold in Europe only, with a five-speed manual and no rear limited-slip differential. The GS Turbo and GSX shared a turbocharged 4G63T of 180 to 195 hp: the 1990 manual GS Turbo was rated at 190 hp and the GSX at 195 hp to offset the extra weight of its all-wheel-drive system, about 2,930 lb against 2,570 lb, and from 1991 both used the 195 hp version. Automatic cars had 180 hp because of smaller injectors and turbocharger.

The basic layout put a transverse 4G37 or 4G63 on the left-hand side of the car driving a gearbox on the right. All-wheel-drive cars had a different transmission with a limited-slip centre differential and a transfer case driving the rear differential and half-shafts. The 4G63 had an iron block, an aluminium head and two balance shafts, while the turbo version ran a lower 7.8:1 compression ratio and oil squirters under the pistons. Engines built from 1989 to April 1992 used a six-bolt crankshaft, and from May 1992 a seven-bolt design. In Europe only one trim was offered, with the 2.0-litre double-overhead-camshaft engine of 150 PS and optional four-wheel drive.

Recalls and later generations

In March 1998 Mitsubishi recalled all 1990 to 1998 Eclipse GSXs because of a transfer case that could lock up through insufficient lubrication and cause a loss of control, and dealers checked the transfer case lubrication. The second generation arrived for 1995 and added a convertible during the 1996 model year. The third generation of 2000 to 2005 used an extended-wheelbase version of the platform shared with the Chrysler Sebring and Dodge Stratus, and the fourth generation of May 2005 returned to Mitsubishi’s own PS platform.

The final Eclipse was built at the end of August 2011 and auctioned for charity, closing the line after four generations. In 2017 Mitsubishi brought the name back on a compact crossover called the Eclipse Cross.
