The Proton Iriz 1.6, produced between 2014 and 2017, represents a significant step forward for Proton, the Malaysian national car manufacturer. Positioned as a mid-range offering within the first generation Iriz (code-named M2) lineup, this variant aimed to provide a balance of performance, fuel efficiency, and affordability in the competitive B-segment hatchback market. The Iriz was intended to replace the aging Proton Savvy and offer a more modern and globally competitive vehicle. It was primarily marketed within Malaysia and select export markets in Southeast Asia, representing Proton’s attempt to establish a stronger foothold in the regional automotive landscape.

Powertrain & Engine Architecture
The heart of the Iriz 1.6 is Proton’s CamPro 1.6-liter inline-four cylinder engine. This engine, designated as the E16, utilizes a multi-point fuel injection system and a double overhead camshaft (DOHC) valvetrain with Variable Valve Timing (VVT). The engine produces 109 horsepower at 5750 rpm and 150 Nm (110.63 lb-ft) of torque at 4000 rpm. The engine’s architecture is relatively conventional, designed for reliability and ease of maintenance. The Iriz 1.6 was exclusively offered with a five-speed manual transmission. This transmission was chosen to maximize fuel efficiency and provide a more engaging driving experience compared to an automatic option, which wasn’t available for this specific engine configuration.
Driving Characteristics
The Iriz 1.6, with its 109 hp and manual transmission, offered a reasonably sprightly driving experience for its class. Acceleration from 0-60 mph took approximately 10.5 seconds, making it competitive with other B-segment hatchbacks. The five-speed manual gearbox provided precise shifts, and the engine felt responsive in the mid-range. While not a performance-oriented vehicle, the Iriz 1.6 was adequate for everyday driving and highway cruising. The gear ratios were tuned for fuel economy, meaning that the engine could feel slightly strained when pushed hard. Compared to the base 1.3-liter engine, the 1.6 offered a noticeable improvement in performance, particularly when carrying passengers or cargo. It provided a more relaxed driving experience, especially on inclines and during overtaking maneuvers.
Equipment & Trim Levels
The Iriz 1.6 typically came equipped with features such as air conditioning, power windows, power steering, and a basic audio system. Safety features included dual airbags, ABS (Anti-lock Braking System), and ISOFIX child seat anchors. Higher trim levels offered additional features like alloy wheels, a multi-function steering wheel, and a more advanced audio system with Bluetooth connectivity. Interior upholstery was typically cloth, with a relatively simple and functional dashboard layout. Optional extras included a reverse parking sensor and a security alarm.
Chassis & Braking
The Iriz 1.6 utilizes a McPherson strut front suspension and a torsion beam rear suspension. This setup provided a comfortable ride quality, although it wasn’t particularly sporty. The front brakes are ventilated discs, while the rear brakes are drums. The steering is rack and pinion with electric power steering, offering light and easy steering feel. The Iriz 1.6’s suspension was tuned for comfort and stability, prioritizing ride quality over handling precision. The use of rear drum brakes was a cost-saving measure common in this segment.
Market Reception & Comparison
The Proton Iriz 1.6 was generally well-received in the Malaysian market, offering a compelling package of features, performance, and price. Critics praised its improved build quality and modern design compared to previous Proton models. However, some reviewers noted that the interior plastics felt somewhat low-rent and that the ride could be a bit firm on rough roads. Compared to the 1.3-liter Iriz, the 1.6 offered a significant performance boost, making it a more appealing option for drivers who frequently travel on highways or carry passengers. Fuel economy was comparable to other B-segment hatchbacks, averaging around 6.5-7.5 liters per 100 kilometers (36-40 mpg) in mixed driving conditions.
Legacy
The Proton Iriz 1.6, while no longer in production, remains a popular choice in the used car market in Malaysia. The CamPro 1.6 engine is known for its relative reliability, although regular maintenance is essential. Common issues include oil leaks and occasional sensor failures. The availability of spare parts is generally good, and the Iriz 1.6 is relatively affordable to maintain. The Iriz represented a turning point for Proton, demonstrating the company’s commitment to improving its product quality and competitiveness. It laid the foundation for future Proton models and helped to revitalize the brand’s image in the Malaysian automotive market.
