In 1994, Proton launched the three-door Proton Satria hatchback and the two-door Proton Putra coupé in 1996, both of which are based on the Wira platform and powered by the same range of Mitsubishi engines offered in the Wira, with the exception of the 2.0L diesel. The Proton Wira saloon and hatchback, and the Proton Satria and Putra were aggressively exported and marketed across the European Union and Middle East during the 1990s. The Proton Perdana, a premium D-segment saloon, was launched in 1995. It is based on the seventh generation 1992 Mitsubishi Eterna and was fitted with Mitsubishi's 4G63 2.0-litre l4 engine. It was offered with the superior 177bhp 6A12 DOHC 2.0L V6 engine after 1999. The Perdana remains the only D-segment, V6-powered car to be commercially produced by Proton. A Citroën AX-based 1.1-litre five-door supermini called the Proton Tiara debuted in 1996. It was the result of a joint venture between Proton and PSA Peugeot Citroën, a collaboration which was later abandoned after the death of Proton's then CEO, Tan Sri Yahaya Ahmad in 1997.
