2021 Proton Iriz (facelift ) Active 1.6 (109 Hp) CVT

Technical Specifications

The Proton Iriz Active 1.6 (109 Hp) CVT, launched in August 2021, represents a mid-cycle refresh of Proton’s B-segment hatchback. This variant occupies a central position within the facelifted Iriz range, offering a balance between performance and fuel efficiency aimed at a broad customer base. The Iriz, first introduced in 2014, is Proton’s offering in a market segment dominated by Perodua in Malaysia, and the 2021 facelift aimed to enhance its appeal with updated styling, improved features, and refined powertrain options. The Active 1.6 CVT trim specifically targets buyers seeking a comfortable and practical daily driver with a reasonable level of equipment.

Powertrain & Engine Architecture

The Proton Iriz Active 1.6 CVT is powered by Proton’s S4PH engine, a 1.6-liter inline-four cylinder naturally aspirated gasoline engine. This engine utilizes a multi-point fuel injection system and a double overhead camshaft (DOHC) valvetrain with variable valve timing (VVT). The S4PH engine is a relatively simple design, prioritizing reliability and affordability over outright performance. It produces 109 horsepower at 5750 rpm and 150 Nm (110.63 lb-ft) of torque at 4000 rpm. The engine is transversely mounted at the front of the vehicle. The engine’s oil capacity is 4.05 liters, and the recommended oil specification is crucial for maintaining its longevity.

The powertrain is completed by a Continuously Variable Transmission (CVT). Proton’s CVT is sourced from Punch Powertrain, a Belgian manufacturer. This CVT is designed to provide smooth, stepless acceleration and improved fuel economy compared to a traditional automatic transmission. However, CVTs are sometimes criticized for their ‘rubber band’ feel and the engine drone during acceleration. The CVT in the Iriz is programmed with simulated gear shifts to mitigate this effect and provide a more familiar driving experience.

Driving Characteristics

The Iriz 1.6 CVT offers adequate performance for everyday driving. While not particularly sporty, the 109 hp engine provides sufficient power for navigating city streets and merging onto highways. The CVT transmission contributes to smooth acceleration, but the lack of fixed gear ratios can result in a less engaging driving experience compared to a manual transmission. The CVT’s programming prioritizes fuel efficiency, meaning the engine often operates at lower rpm, which can sometimes feel sluggish when requiring quick bursts of acceleration. The weight-to-power ratio of 10.9 kg/Hp translates to a 0-60 mph time estimated around 12-13 seconds, placing it behind many of its competitors.

Equipment & Trim Levels

The Active trim level of the Iriz sits in the middle of the range. Standard features include power windows, power side mirrors, a basic audio system with Bluetooth connectivity, and air conditioning. Safety features include dual airbags, ABS (Anti-lock Braking System), and ISOFIX child seat anchors. The interior typically features fabric upholstery and a relatively simple dashboard layout. Optional extras available for the Active trim could include a touchscreen infotainment system, reverse parking sensors, and upgraded interior trim materials. The Iriz Active aims to provide a good balance of features for the price point.

Chassis & Braking

The Iriz utilizes a McPherson strut suspension setup at the front and a torsion beam suspension at the rear. This configuration is common in B-segment hatchbacks, offering a compromise between ride comfort and handling. The front suspension incorporates a transverse stabilizer bar to reduce body roll during cornering. The braking system consists of ventilated discs at the front and drum brakes at the rear. While adequate for normal driving conditions, the rear drum brakes are a cost-saving measure and don’t offer the same stopping power as disc brakes. The electric power steering provides light and easy steering feel, making it well-suited for urban driving.

Market Reception & Comparison

The Proton Iriz 1.6 CVT received mixed reviews upon its launch. Critics generally praised its improved styling and interior quality compared to the pre-facelift model. However, the powertrain was often criticized for its lack of refinement and relatively low power output. Compared to the Perodua Myvi, the Iriz’s main competitor in the Malaysian market, the Iriz offered a slightly more spacious interior and a more comfortable ride, but the Myvi was generally considered to be more fuel-efficient and better value for money. The Iriz 1.6 CVT’s fuel economy is rated around 6.5 liters per 100 kilometers (approximately 36 mpg), which is competitive but not class-leading.

Legacy

The Proton Iriz, and specifically the 1.6L CVT variant, has established itself as a reasonably reliable and affordable option in the used car market. The S4PH engine is known for its durability, provided it receives regular maintenance. The CVT transmission, while sometimes prone to issues if not properly serviced, has generally proven to be reliable in the Iriz. The Iriz represents Proton’s attempt to compete in the increasingly competitive B-segment hatchback market, and while it may not be the most exciting or technologically advanced vehicle in its class, it offers a practical and affordable transportation solution for many buyers. Its continued presence on the roads is a testament to its overall reliability and value proposition.
