2012 Proton Preve 1.6 (109 Hp) CVT

The Proton Preve 1.6, equipped with a 109 horsepower engine and a Continuously Variable Transmission (CVT), was a front-wheel-drive compact sedan produced by the Malaysian automaker Proton from 2012 onwards. Positioned as a mainstream offering within the Preve range, it aimed to provide a balance of fuel efficiency and affordability for the Southeast Asian market, and later, select export markets. The Preve represented Proton’s attempt to modernize its lineup and compete with established Japanese and Korean rivals in the C-segment sedan class. It was built on a platform derived from Proton’s collaboration with Mitsubishi Motors.

Technical Specifications

INTRODUCTION

The Proton Preve 1.6 CVT, launched in 2012, was a key model in Proton’s efforts to revamp its image and offer a more competitive product in the compact sedan segment. It was part of the first generation of the Preve (launched in 2012), built on a platform co-developed with Mitsubishi, and represented a significant step forward in terms of design and technology compared to Proton’s previous offerings. The 1.6L CVT variant was intended to appeal to buyers seeking a comfortable, fuel-efficient, and affordable daily driver. It sat in the middle of the Preve lineup, offering a compromise between the base 1.3L engine and the more powerful 1.6L Turbo model.

Powertrain & Engine Architecture

The heart of the Preve 1.6 CVT is Proton’s CamPro 1.6-liter inline-four cylinder engine. This engine, designated as the CFE, utilizes a multi-point fuel injection system and a double overhead camshaft (DOHC) valvetrain. The engine produces 109 horsepower at 5750 rpm and 150 Nm (110.63 lb-ft) of torque at 4000 rpm. The engine’s 10:1 compression ratio is a balance between efficiency and performance. The engine is transversely mounted at the front of the vehicle. Paired with the engine is a six-speed Continuously Variable Transmission (CVT). This CVT, sourced from Punch Powertrain, was chosen for its smooth operation and fuel efficiency. Unlike traditional automatic transmissions with fixed gear ratios, the CVT provides a seamless and continuously variable gear ratio, optimizing engine speed for the driving conditions.

Driving Characteristics

The Preve 1.6 CVT offers a comfortable and predictable driving experience. The CVT transmission contributes to smooth acceleration, although it lacks the immediate responsiveness of a traditional automatic or manual gearbox. Acceleration from 0 to 60 mph takes approximately 11.9 seconds, and the car has a top speed of 170 km/h (105.63 mph). The CVT is programmed to mimic traditional gear shifts at higher throttle inputs, providing a more familiar feel for drivers accustomed to conventional automatics. However, under hard acceleration, the engine can sometimes feel strained, as the CVT holds the engine at a constant high RPM. Compared to the manual transmission version of the 1.6L Preve, the CVT offers slightly reduced performance due to the power loss inherent in the transmission. The 1.6 Turbo variant, with its significantly higher power output, provides a much more engaging and dynamic driving experience.

Equipment & Trim Levels

The Preve 1.6 CVT typically came equipped with a reasonable level of standard features. These included air conditioning, power windows, power door locks, and a basic audio system with USB connectivity. Higher trim levels added features such as alloy wheels, fog lamps, a multi-function steering wheel, and an upgraded audio system. Interior upholstery was typically cloth, with options for leather seats on higher-spec models. Safety features included dual front airbags, ABS (Anti-lock Braking System), and Electronic Brake-force Distribution (EBD). Optional extras included a reverse parking sensor, a security alarm, and various body kits.

Chassis & Braking

The Preve 1.6 CVT utilizes an independent McPherson strut suspension at the front and an independent multi-link suspension at the rear, providing a comfortable ride and decent handling characteristics. A stabilizer bar is included on both axles to reduce body roll during cornering. The braking system consists of ventilated discs at the front and solid discs at the rear. The ABS system helps to prevent wheel lockup during hard braking, enhancing safety. The Preve’s chassis was designed to provide a balance between ride comfort and handling, making it suitable for everyday driving conditions.

Market Reception & Comparison

The Proton Preve 1.6 CVT was generally well-received by the Malaysian motoring press as a significant improvement over previous Proton models. Critics praised its modern design, comfortable interior, and fuel efficiency. However, some reviewers noted the engine’s lack of outright power and the CVT’s sometimes sluggish response. Compared to rivals like the Toyota Corolla Altis and Honda Civic, the Preve offered a more affordable price point but lacked the established reputation for reliability and resale value of its Japanese competitors. Fuel economy was a strong point, with the CVT helping to achieve a combined fuel consumption of 5.8 l/100 km (40.6 US mpg).

Legacy

The Proton Preve, while not a runaway sales success, played an important role in Proton’s efforts to modernize its product lineup. The 1.6L CVT variant remains a relatively common sight on Malaysian roads today. The CamPro 1.6 engine, while not known for exceptional durability, has proven to be reasonably reliable with proper maintenance. Used examples of the Preve 1.6 CVT are generally affordable, making them an attractive option for budget-conscious buyers. However, potential buyers should be aware of the potential for CVT transmission issues, and regular servicing is crucial to ensure long-term reliability.
