The Proton Waja, the company's first indigenously designed model, was launched in August 2000. It however still had a Mitsubishi 4G18 engine at launch as Proton's first in-house Campro engine was not yet available. The Waja marked the end of Proton's extensive reliance on other car manufacturers for vehicle platforms and components. However, the model was only a moderate seller, being significantly outsold by Proton's own much older and slightly smaller Proton Wira. The Waja also marked the start of a decline in the local market-leading Proton marque which led to Perodua, the second Malaysian vehicle manufacturer, eventually capturing Proton's sales crown in 2006. In 2002, Proton introduced the Arena, a ute based on the Proton Wira platform and thus far the only Proton model to enjoy significantly more popularity in its export markets (specifically Australia) than domestically. The Proton Gen-2, a hatchback model, was launched in late 2004. It was the first Proton vehicle equipped with the all-new Malaysian-made Campro engine.
