Powertrain & Engine Architecture
The heart of the Colt CZT is the 4G15 1.5-liter inline-four cylinder engine. This engine is notable for its implementation of a turbocharger and intercooler, significantly boosting its output compared to the naturally aspirated 1.3 and 1.5-liter engines available in other Colt VI models. The 4G15 features a DOHC (Double Overhead Camshaft) valvetrain and multi-point fuel injection. The turbocharger provides increased air intake, resulting in a power output of 150 horsepower at 6000 rpm and 210 Nm (155 lb-ft) of torque at 4000 rpm. This engine code, 4G15, is a key identifier for this specific turbocharged variant. The engine’s relatively small displacement and turbocharging contribute to a good balance of performance and fuel efficiency. The standard transmission for the CZT was a five-speed manual gearbox, optimized for the engine’s powerband.
Driving Characteristics
The 1.5 i 16V CZT offered a noticeably more spirited driving experience than the base Colt models. The turbocharger provides a distinct boost in power, particularly in the mid-range, making overtaking and highway driving more effortless. While not a particularly fast car by modern standards, the CZT’s 0-60 mph time of around 7.6 seconds was respectable for its class and price point. The five-speed manual transmission allows for precise control over the engine’s power, and the gear ratios are well-suited to maximizing the turbocharger’s effectiveness. Compared to the naturally aspirated versions, the CZT demanded more attentive driving, as the turbocharger’s boost came on relatively abruptly. The handling was generally considered competent, though not exceptionally sporty, with a focus on providing a comfortable and predictable ride.
Equipment & Trim Levels
The CZT trim level typically included several features not found on the base Colt models. Standard equipment often included alloy wheels, a sports-tuned suspension, air conditioning, power windows, and a basic audio system. Interior upholstery was typically cloth, with a sporty design. Optional extras could include features like a sunroof, upgraded audio systems, and metallic paint finishes. The CZT was positioned as the mid-range performance option, offering a balance of features and affordability. It sat above the base models but below any potential limited-edition or higher-specification variants that might have been offered in certain markets.
Chassis & Braking
The Colt CZT utilized a front-wheel-drive layout with a MacPherson strut front suspension and a torsion beam rear suspension. The front brakes were ventilated discs, providing adequate stopping power, while the rear brakes were solid discs. ABS (Anti-lock Braking System) was standard equipment. The suspension was tuned to provide a slightly firmer ride than the standard Colt, enhancing handling and stability. The chassis was reinforced in certain areas to cope with the increased power output of the turbocharged engine. The weight distribution was reasonably balanced, contributing to predictable handling characteristics.
Market Reception & Comparison
The Mitsubishi Colt CZT was generally well-received by automotive critics as an affordable and enjoyable hot hatch. It was praised for its punchy turbocharged engine, responsive handling, and relatively low running costs. However, some critics noted that the interior quality was somewhat basic and that the styling was not particularly striking. Compared to rivals like the Renault Clio Sport and the Ford Fiesta ST, the CZT offered a slightly more refined driving experience but lacked the outright performance of some of its competitors. Fuel economy was a strong point, with combined fuel consumption figures around 34 mpg. Reliability was generally good, although turbocharger issues could occasionally arise with improper maintenance.
Legacy
The Mitsubishi Colt CZT has developed a modest following among enthusiasts, particularly those seeking an affordable and reliable hot hatch. The 4G15 engine, while not without its potential issues, is generally considered durable and relatively easy to maintain. In the used car market, the CZT represents a good value proposition for buyers looking for a fun-to-drive and practical hatchback. Parts availability is generally good, although some specific components may become increasingly difficult to find as the car ages. The CZT remains a testament to Mitsubishi’s ability to produce engaging and affordable vehicles, and it continues to be appreciated by those who value its unique blend of performance, practicality, and reliability.
