Hybrid Campro engine

In March 2007, Proton and Lotus have announced their concept model of a Proton Gen-2 powered by a hybrid powerplant that uses the Campro engine. The concept model was revealed during the 2007 Geneva Motor Show from 8 ~ 18 March 2007

The hybrid powerplant system, which is known as EVE system (Efficient, Viable, Environmental) will be using the same S4PH engine as the one that powers the present gasoline version of the Gen-2, combined together with a 30 kW, 144V electric motor. The main purpose of the hybrid powerplant system is to provide a hybrid system that can be retrofitted to existing models, retaining the same powerplant and also eliminates the need to develop a completely different platform, like the Honda Civic Hybrid. Unlike the IMA (Integrated Motor Assist) technology in the Civic Hybrid which uses a bulky Ni-MH battery pack, the EVE Hybrid system will use a Li-ion battery pack inside the engine bay.

The EVE Hybrid System will have 3 key technologies:-

“Micro-hybrid” start-stop system - An integrated starter-alternator system is installed to switch off the engine automatically when the engine stops, for example at the traffic light. The engine will automatically restart when the gas pedal is depressed.
Full parallel hybrid technology - Combines the existing S4PH engine with a 30 kW, 144V electric motor, resulting in higher power (141 bhp combined), higher torque (233 N-m combined), lower emission (up to 22% carbon dioxide reduction) and better fuel economy (up to 4.6 L/100 km[13]). The system also includes regenerative braking system.

Continuously Variable Transmission (CVT) - The CVT system provides an infinite number of gear ratios for better efficiency.

The combined power and torque for the powerplant system are as follows:-

Max power (gasoline engine only): 110 bhp (82 kW/112 PS) @ 6,000 rpm
Max torque (gasoline engine only): 148 N·m (109 ft·lbf) @ 4,000 rpm
Max power (combined): 141 bhp (105 kW/143 PS) @ 5,500 rpm
Max torque (combined): 233 N·m (172 ft·lbf) @ 1,500 rpm (limited to 180 N-m continuous)
Proton will start commercializing their upcoming hybrid vehicles equipped with the EVE Hybrid System within 2010-2011
