The Proton Iriz (facelift 2017) 1.3, producing 95 horsepower with a Continuously Variable Transmission (CVT), represented an entry-level offering within the second-generation Iriz range. Introduced in 2017 and remaining in production through 2018, this variant aimed to provide affordable and fuel-efficient transportation for the Malaysian market, and to a lesser extent, export markets within Southeast Asia. It was positioned as the most accessible trim level, targeting first-time car buyers and those prioritizing economy over outright performance. The facelift brought styling updates and minor mechanical revisions to the original Iriz, enhancing its appeal and addressing some initial criticisms.

Powertrain & Engine Architecture
The heart of the Iriz 1.3 CVT was Proton’s CamPro 1.3-liter inline-four engine. This engine, designated as the E13A, featured a double overhead camshaft (DOHC) design with variable valve timing (VVT) on the intake camshaft. The multi-point fuel injection system delivered fuel to the cylinders, and the engine produced 95 horsepower at 5750 rpm and 120 Nm (88.51 lb-ft) of torque at 4000 rpm. The engine’s relatively modest output was paired with a CVT (Continuously Variable Transmission) sourced from Punch Powertrain. This CVT offered seamless gear changes and aimed to maximize fuel efficiency, but at the expense of a more engaging driving experience compared to a traditional automatic or manual transmission.
Driving Characteristics
The Iriz 1.3 CVT’s driving experience was characterized by its smooth, if somewhat uninspiring, acceleration. The CVT effectively kept the engine within its optimal power band, but lacked the distinct gear shifts of a conventional automatic. This resulted in a ‘rubber band’ feel, where engine speed would rise proportionally to throttle input, without a corresponding immediate increase in vehicle speed. While adequate for urban driving and highway cruising, the 95 hp engine and CVT combination didn’t offer particularly brisk performance. Compared to the higher-spec 1.6-liter variants, the 1.3 felt noticeably slower, especially when fully loaded or tackling inclines. The CVT’s programming prioritized fuel economy, which meant that aggressive acceleration was met with a delayed response.
Equipment & Trim Levels
The 1.3 CVT trim of the Iriz facelift typically included basic amenities such as air conditioning, power windows, and central locking. Safety features included dual airbags and ABS (Anti-lock Braking System). Interior upholstery was generally fabric, with a simple dashboard layout. Optional extras, depending on the package selected, could include a touchscreen infotainment system with Bluetooth connectivity, steering wheel-mounted audio controls, and rear parking sensors. The overall interior design was functional and practical, reflecting the car’s budget-oriented positioning.
Chassis & Braking
The Iriz utilized a McPherson strut front suspension and a torsion beam rear suspension. The front suspension incorporated a stabilizer bar to reduce body roll during cornering. Braking duties were handled by ventilated discs at the front and drum brakes at the rear. The braking system, while adequate for everyday use, wasn’t particularly powerful, and the rear drum brakes limited overall stopping performance. The Iriz’s chassis was designed to balance ride comfort with handling stability, offering a reasonably compliant ride on most road surfaces.
Market Reception & Comparison
The Proton Iriz 1.3 CVT was generally well-received as an affordable and practical hatchback. Critics praised its fuel efficiency and spacious interior for its size. However, the engine’s lack of power and the CVT’s ‘rubber band’ feel were common criticisms. Compared to the 1.6-liter variants, the 1.3 offered significantly lower performance but also a lower price point. It competed primarily with other budget-oriented hatchbacks in the Malaysian market, such as the Perodua Myvi. Fuel economy was a key selling point, with the 1.3 CVT achieving respectable figures in real-world driving conditions.
Legacy
The Proton Iriz 1.3 CVT, while not a performance standout, served as an important entry point into the Iriz range. Its affordability and fuel efficiency made it a popular choice for budget-conscious buyers. The CamPro 1.3 engine, while known for its reliability, required regular maintenance to ensure optimal performance. In the used car market, these models are generally available at very affordable prices, making them attractive options for first-time car owners or those seeking a basic, economical runabout. The CVT transmission, while generally reliable, may require servicing or eventual replacement at higher mileages, representing a potential long-term maintenance cost.
