Proton is currently in talks with foreign parties on the development of higher displacement engines such as 1.8 litre and 2.0 litre to complement the existing Campro IAFM and Campro CPS range of 1.3 and 1.6 litre engines. Something will be announced by mid-2008 regarding this, and it will likely involve a tie-up with a foreign car manufacturer.
Proton is also looking into diesel engines for its cars, as diesels are important for new markets that Proton wants to enter such as the Indian market. A foreign partner will also be a part of this as it would be very costly to self-develop a diesel engine all by its own.
In India, the availability of a diesel engine can make or break a model. Lackluster sales of compact cars such as the Chevrolet Aveo notchback sedan are attributed to the lack of a diesel engine by many Indian automotive journalists.
