Proton Impian (01-07) - Review Review by Parkers on 01 January 2001 Last Updated: 24 May 2007 Proton's largest model is also the first to be designed and built in-house by the Malaysian firm. Even so, Lotus (part-owned by Proton) has given them more than a helping hand with the ride and handling, which are very good. The 1.6 engine is frugal but unrefined, so needs to be worked to get the most from it. 2 out of 5 Other Proton reviews Summary Facts & Figures Equipment Driving & Performance Comfort Costs Safety & Reliability Buying & Selling Also Consider Company Car Info Owners' Reviews Gallery 2.5 out of 5 Performance Just one engine available, a Mitsubishi-sourced 1.6 petrol. It's surprisingly frugal (42mpg on the combined cycle), although it's noisy, needs to be worked hard and struggles to get up to motorway speeds. 3.5 out of 5 Handling Proton left this to Lotus - and they've done a good job. It's a responsive car to drive, with little roll, direct steering and plenty of grip. Ride quality is better than you would expect - far better than older Protons.
