Proton has named its new hybrid system i-HEV, confirming that it will debut in the upcoming model codenamed AMA 02. Announced on 10 November, the system combines a petrol engine and two motors, with its battery replenished by engine generation and regenerative braking.
Engine and electric drive
The 1.5-litre naturally aspirated Atkinson-cycle engine produces 111 PS and 136 Nm. Proton claims peak thermal efficiency of 46.5%. The main drive motor is rated at up to 163 PS and 220 Nm.
In the Dedicated Hybrid Transmission, the P1 motor starts the engine and generates electricity. The P3 motor drives the vehicle and recovers energy during deceleration.
Four modes, managed automatically
Depending on speed, power demand and battery condition, the controller selects electric-only, series, parallel or direct engine drive. The system uses a 1.38kWh battery and requires no external charging.
Proton also confirmed local engine production and assembly of hybrid transmissions and electric drive units at Tanjong Malim. AMA 02’s retail name, price and launch date remain to be announced.
