The Mitsubishi Starion is a two-door, turbocharged four-cylinder rear-wheel drive four-seat hatchback sports car manufactured and marketed by Mitsubishi from 1982 until 1989 — with badge engineered variants marketed in North America as the Conquest, under the Chrysler, Dodge, and Plymouth brands.
The Starion was one of the first modern Japanese turbocharged performance automobiles with electronic fuel injection, following the earlier Isuzu 117 Coupé.
Overview
Mitsubishi began marketing the Starion in 1982, during a period in which a number of Japanese grand tourer (GT) sports cars were available, including the Nissan Z cars, Mazda RX-7, Toyota Supra and to a lesser extent, the Honda Prelude, Isuzu Piazza and Subaru XT.
The Starion was marketed in the US as the Mitsubishi Starion and badge engineered variants of it were marketed as the Dodge, Plymouth and Chrysler Conquest. In the UK it was sold as the Colt Starion.
It was manufactured in two body configurations, a narrowbody and widebody; the narrower style complied with Japanese exterior dimension regulations taxing larger vehicles and engine displacement exceeding two liters. Only the narrowbody was offered through the 1985.5 model year.
The introduction of the widebody also split the car into two ranges: a non-intercooled lower-horsepower car using the narrow body style and a high-performance intercooled widebody. In most markets, widebody cars were given the label of Starion ESI-R or Conquest TSi. Markets that never received the widebody had the ESI-R label, these cars had similar performance as the widebodies. Widebody cars were offered in 1986-1989 model years in the US.
The Starion was the featured vehicle in the 1984 movie Cannonball Run II.
Name
Mitsubishi says "Starion" is a contraction of "Star of Arion" — and refers to both a star and the mythical horse, Arion. The cover of the original Japanese Starion sales brochure, published by Mitsubishi (May 1982) carried the text: "the name STARION — derived from the combination of star and Arion, Hercules' horse in Greek mythology, symbolizes a sense of the universe, and of power and high performance.Several sources attribute the name to struggles by Japanese engineers to pronounce the word stallion. An early Japanese television commercial for the Starion closed with a logo of a stallion's head with the word "Starion" below it. One translation of the voiceover says the name refers to a star and the mythical horse, Arion. The Mitsubishi Colt and Mitsubishi Eclipse featured equine names, with the Eclipse named after the champion racehorse.
Design
The Starion uses a traditional front-mounted engine with rear-wheel drive layout. Many came with a limited slip differential and anti-lock brakes (single channel, rear wheels only) as standard features. The entire chassis was derived from the previous high-performance variant of the Mitsubishi Sapporo or Mitsubishi Galant Lambda sports coupé, with a MacPherson strut suspension and sway bars that were fitted to the front and rear. Rack and pinion steering was not offered, instead gearbox steering was standard on all models.
Engine capacity differed between markets. American customers received the larger SOHC Astron G54B 2.6 L engine. Most markets received the SOHC 2.0 L Sirius G63B engine, subsequently featured in DOHC form in later Mitsubishi sport compacts such as the Mitsubishi Lancer Evolution. Both the 2.0 L and the 2.6 L produced roughly the same horsepower, the larger 2.6 L did have a slight torque advantage and the 2.0L had a higher redline. Reporters of the time considered the 2.0l to be peaky and exciting, while the American market 2.6l had plenty of torque, but was less rewarding. Both engines featured computer-controlled fuel injection and turbocharging. After 1987, European Starion models were also fitted with the 2.6 L engine, as was the GSR-VR for Japan. The move to the 2.6 L in all markets was spurred by emissions restrictions around the world tightening to meet the American standards for lead in fuels. Reviews during the change were negative as many felt the car was slower, for most of these markets this was the case as the engine change also coincided with a move to the heavier body style.
From 1984 until 1987 in Japan a 12-valve (two intake, one exhaust) SOHC intercooled version of the 2.0 L G63B was made available in the top-spec GSR-V (and some GSR-VR) trim grade Starions. This setup was known as the Dual Action Super Head (or DASH for short) due to its ability to activate the third intake valve above a certain RPM, thereby increasing top end response, flow and overall engine performance. Redline was increased to 7000 rpm on these models.
