Performance
Proton owns Lotus Cars that was involved in the development of the car. The Gen-2 is the first Proton model to use the new Proton/Lotus developed Campro engine. Although the Gen-2's S4PH 1.6-litre engine delivers a claimed 0–100 km/h time of 11.2 seconds (manual transmission) and a contemporary maximum power output of 110 PS (81 kW; 108 hp) at 6000rpm, it suffers from poor mid-range torque.
This is due to a torque dip in the crucial 2,000 - 3,000rpm operating range, where the torque output decreases slightly before picking up back to its peak torque, which is delivered at 4,000rpm. This torque characteristic can clearly be seen in manufacturer published engine performance curves and is widely attributed to the missing Camshaft Profiling System (CPS) technical feature that the engine was named after, but which did not make production, to save costs.
The original (non-CPS) Gen-2's ECU's Engine and Automatic Transmission mapping has been modified several times since the car's launch to improve perceived mid-range pick-up, but the upgrades did not markedly improve the cars' driveability.
This undesirable torque dip was eventually corrected by Proton in 2008 with the introduction of the "new" CamPro engine, designated CamPro CPS, which finally delivered camshaft profiling (variable valve timing) as part of the engine specification.

Famous quotes containing the word performance:
“Tennis is more than just a sport. It’s an art, like the ballet. Or like a performance in the theater. When I step on the court I feel like Anna Pavlova. Or like Adelina Patti. Or even like Sarah Bernhardt. I see the footlights in front of me. I hear the whisperings of the audience. I feel an icy shudder. Win or die! Now or never! It’s the crisis of my life.”
—Bill Tilden (1893–1953)
“O world, world! thus is the poor agent despised. O traitors and bawds, how earnestly are you set a-work, and how ill requited! Why should our endeavour be so loved, and the performance so loathed?”
—William Shakespeare (1564–1616)
“The way to go to the circus, however, is with someone who has seen perhaps one theatrical performance before in his life and that in the High School hall.... The scales of sophistication are struck from your eyes and you see in the circus a gathering of men and women who are able to do things as a matter of course which you couldn’t do if your life depended on it.”
—Robert Benchley (1889–1945)
