The Proton Gen-2 is an automobile manufactured by Malaysian carmaker Proton, and was launched in the third quarter of 2004. The Gen-2 uses a platform which is mostly Malaysian-developed. Loosely based on a mid-90s Mitsubishi chassis, the platform has been extensively developed by Proton and their partner Lotus. The Gen-2 was initially codenamed the Proton Wira Replacement Model, hinting that the car was to replace the Proton Wira. The name Gen-2 is an abbreviation of 'Generation 2', to mark the success of Proton which is using its own engine for the car.

The Gen-2's platform is also used by the Proton Satria Neo (with a shortened wheelbase) and the Proton Persona (with an extended rear hang to form a more sedan-like body).


Lotus Cars, which is owned by Proton was instrumental in the development of the car which is mainly evident in the car's world-class ride and handling characteristics. The Gen-2 is the first Proton model to use the new Proton/Lotus developed Campro engine. Even though the S4PH 1.6L engine, the first capacity fitted to the Gen-2, is contemporary in maximum power output, it suffers from poor mid-range torque.

This is due to its torque dip in the crucial 2,000 to 3,000 rpm operating range, where the torque actually decreases slightly before picking up back to its peak torque at 4,000 rpm. This torque characteristic can clearly be seen in manufacturer published engine performance curves and is widely attributed to the missing Camshaft Profiling technical feature that the engine was named after, but which was dropped from production probably for cost reasons. However, this torque dip was corrected by Proton in 2008 with a new Campro CPS engine.

The Gen-2's ECU Engine and Automatic Transmission mapping has been modified several times since the car's launch to improve perceived driving characteristics, but have not resulted in changes to manufacturer's torque and power curves and figures.

Competing cars

In Malaysia, the car goes head-to-head against the likes of the Hyundai Accent (Verna) and Kia Rio (Pride), but undercut these by about 20 percent. Against the ASEAN-made Honda City and Toyota Vios, the discount is even greater, at about 30 percent. Proton's price advantage in Malaysia can be attributed to a discriminatory tax structure that an ASEAN trade agreement was supposed to disallow by 2005, but which now has January 2008 as its postponed deadline.

Changes and facelifts

In 2005, a lower-spec version of Proton Gen-2 powered by 1.3L Campro engine was made available in Malaysia with automatic transmission option only.

In December 2007, a new facelifted Proton Gen-2 was unveiled in Thailand in conjunction with the carmaker's entry into the Thai market. It also marks the first production Proton with the Campro CPS engine installed in the engine bay. The CPS variant is a High Line model only, producing 127 horsepower compared to a normal Campro's 110.

On the 3rd of March 2008, the facelifted 2008 Proton Gen-2 was launched in Malaysia. Two variants are available. The medium line variant is powered by the Campro IAFM engine, while the high line version uses the more powerful Campro CPS engine. Exterior changes include a new front bumper and rear spoiler, while the interior gets a new dashboard incorporating a glovebox, new door panels, and leather seats for the high line version
