INTRODUCTION
The Proton Perdana I 2.0 i V6 24V, produced from 1998 to 2010, was the flagship model of the first-generation Perdana. It represented Proton’s ambition to create a domestically-produced luxury sedan capable of competing with imported models. Based heavily on the eighth-generation Mitsubishi Galant, the Perdana I underwent significant localization of parts and assembly within Malaysia. The 2.0L V6 variant was positioned as the top-of-the-line offering, providing a substantial performance upgrade over the 1.6L and 1.8L inline-four cylinder options. It catered to a market segment desiring a comfortable, spacious, and relatively powerful sedan for executive transport and family use.
Powertrain & Engine Architecture
At the heart of the Perdana I 2.0 i V6 lies the Mitsubishi 6A12 engine, a 2.0-liter (1999 cc) DOHC 24-valve V6. This engine, known for its smoothness and relative reliability, produces 150 horsepower at 6750 rpm and 179 Nm (132 lb-ft) of torque at 4000 rpm. The engine utilizes a multi-port fuel injection system, delivering fuel directly to each intake port for optimized combustion. The 6A12 engine is a naturally aspirated design, relying on atmospheric pressure for air intake. Paired with this engine is a four-speed automatic transmission, providing convenient shifting for everyday driving. This transmission, while not offering the efficiency of modern gearboxes, was chosen for its smoothness and reliability. The engine is transversely mounted in the front of the vehicle, driving the front wheels.
Driving Characteristics
The Perdana I 2.0 i V6 offered a noticeable improvement in performance compared to its four-cylinder siblings. While not a sports sedan, the V6 engine provided ample power for comfortable highway cruising and confident overtaking. Acceleration from 0 to 60 mph was achieved in approximately 12.4 seconds, and the car had a top speed of around 127 mph. The four-speed automatic transmission, while smooth, did result in relatively wide gear ratios. This meant that the engine could feel somewhat strained during hard acceleration, and fuel economy suffered compared to the manual transmission options available in other Perdana I models. The suspension was tuned for comfort, providing a smooth ride over most road surfaces, but it wasn’t particularly sporty in handling.
Equipment & Trim Levels
The 2.0 i V6 variant of the Perdana I typically came well-equipped, reflecting its position as the premium model. Standard features included power windows, power door locks, central locking, air conditioning, and an upgraded audio system. Interior upholstery was typically cloth, although leather options were available as upgrades. Dashboard configuration featured woodgrain accents and a relatively straightforward layout. Optional extras included a sunroof, upgraded sound system with a CD changer, and alloy wheels. The overall interior ambiance was designed to provide a comfortable and refined experience for both driver and passengers.
Chassis & Braking
The Perdana I utilized a front-engine, front-wheel-drive layout. The front suspension consisted of a MacPherson strut setup, while the rear employed a coil spring arrangement. Braking duties were handled by ventilated discs at the front and solid discs at the rear. An Anti-lock Braking System (ABS) was standard equipment, enhancing safety by preventing wheel lockup during hard braking. Steering was rack and pinion, assisted by hydraulic power steering for ease of maneuverability. The car rode on 205/55 R16 tires, providing a good balance of comfort and grip.
Market Reception & Comparison
The Proton Perdana I 2.0 i V6 was generally well-received in the Malaysian market. Critics praised its spacious interior, comfortable ride, and relatively powerful engine. However, some criticisms were leveled at the car’s fuel economy, which was higher than that of the four-cylinder models. Compared to the 1.8L variant, the V6 offered a significant performance boost, but at the cost of increased fuel consumption and a slightly higher purchase price. Compared to imported rivals, the Perdana I 2.0 i V6 offered a compelling value proposition, providing a similar level of comfort and features at a lower price point.
Legacy
The Proton Perdana I 2.0 i V6 remains a popular choice among enthusiasts and collectors in Malaysia. The 6A12 engine, while aging, is known for its durability and relatively straightforward maintenance. Parts availability can be a concern, but many components are still readily available through local suppliers and online marketplaces. The Perdana I 2.0 i V6 represents a pivotal moment in Proton’s history, demonstrating the company’s ability to produce a locally-designed and manufactured executive sedan. Today, well-maintained examples of this car are sought after for their classic styling, comfortable ride, and historical significance.
