The Mitsubishi Colt IV 1.8 GTi (CAO), produced between 1992 and 1996, represented a performance-oriented variant within the fourth generation of the Mitsubishi Colt. Positioned as the flagship model in the CAO series, the 1.8 GTi aimed to deliver a sporty driving experience in a compact hatchback package. It was primarily marketed in Europe and other international markets, offering a more engaging alternative to the standard Colt models. The Colt IV, built on the A3 platform, sought to blend practicality with a degree of youthful appeal, and the GTi trim was central to that strategy.

Powertrain & Engine Architecture
The heart of the Colt 1.8 GTi was the 4G93 engine, an 1834cc (1.8-liter) inline-four cylinder gasoline engine. This engine featured multi-port fuel injection and a 10:1 compression ratio. The 4G93 was known for its relatively free-revving nature and willingness to produce power throughout the RPM range. The engine utilized a single overhead camshaft (SOHC) design with four valves per cylinder, contributing to its respectable output for its displacement. The five-speed manual transmission was the only gearbox option available with the GTi, designed to maximize the engine’s performance potential. The transmission featured relatively short gear ratios, aiding in quick acceleration.
Driving Characteristics
The 1.8 GTi offered a noticeably more spirited driving experience compared to the lower-spec Colt models. The 140 horsepower output, combined with the lightweight chassis (approximately 995 kg or 2194 lbs), resulted in a 0-60 mph time of around 7.2 seconds and a top speed of 130 mph. While not a sports car by modern standards, the GTi provided brisk acceleration and agile handling. The McPherson strut front suspension and disc brakes on all four wheels contributed to a stable and controlled ride. The steering, aided by hydraulic power assistance, offered decent feedback, though it wasn’t particularly sharp. Compared to potential alternatives like the Volkswagen Golf GTI of the same era, the Colt GTi offered a more affordable entry point into the hot hatch segment, albeit with slightly less refinement.
Equipment & Trim Levels
The 1.8 GTi trim level included several features designed to enhance the driving experience and provide a degree of comfort. Standard equipment typically included sports seats with enhanced bolstering, a leather-wrapped steering wheel, and a more comprehensive instrument cluster with additional gauges (such as a tachometer). Exterior features often included a rear spoiler, alloy wheels, and a more aggressive body kit. Optional extras could include air conditioning, a sunroof, and upgraded audio systems. The interior materials were generally of good quality for the price point, though they weren’t as luxurious as those found in more expensive hot hatches.
Chassis & Braking
The Colt IV utilized a front-wheel-drive layout with an independent McPherson strut suspension at the front and a torsion beam rear suspension. The front brakes were ventilated discs, providing good stopping power, while the rear brakes were solid discs. The chassis was relatively lightweight, contributing to the car’s agility. The steering system employed a rack-and-pinion setup with hydraulic power assistance. While the suspension wasn’t particularly sophisticated, it provided a reasonable balance between ride comfort and handling performance. Stabilizer bars were fitted to both the front and rear axles to reduce body roll during cornering.
Market Reception & Comparison
The Mitsubishi Colt 1.8 GTi was generally well-received by automotive critics as an affordable and fun-to-drive hot hatch. It was praised for its lively engine, nimble handling, and practical hatchback body style. However, some critics noted that the interior lacked the refinement of more established competitors, such as the Peugeot 205 GTI or the Renault Clio Williams. Fuel economy was reasonable for a performance-oriented vehicle, averaging around 30-35 mpg in mixed driving conditions. Reliability was generally good, though routine maintenance was essential to keep the engine running smoothly. Compared to the standard Colt models, the GTi offered a significant performance upgrade, making it a popular choice for younger drivers and those seeking a more engaging driving experience.
Legacy
The Mitsubishi Colt IV 1.8 GTi has developed a modest following among enthusiasts in recent years. While not as highly sought after as some of its more iconic rivals, the GTi remains a relatively affordable and enjoyable classic hot hatch. The 4G93 engine is known for its durability and relatively simple construction, making it easier to maintain and repair. Parts availability can be a challenge in some regions, but many components are still available through specialist suppliers. Today, the Colt 1.8 GTi represents a nostalgic reminder of a time when hot hatches were about accessible performance and driving enjoyment, rather than outright speed and technological complexity. A well-maintained example can still provide a rewarding and engaging driving experience.
