Hyundai Mild Hybrid MHEV Powertrains Explained

[@rpatel9901]

ive heard that it increases the tork so helps acceleration but how can it do that if the engine isnt driven by a motor

The mild hybrids (MHEV) don't have enough battery power to add any more power/torque. The slightly larger battery helps with the stop/start, so improves the efficiency and economy slightly. The Hybrid cars have larger batteries and electric motors, so that's where you see improved Torque.

@@SGPetchLtd thanks yes i was aware of that but the regular i20 engine ia a 1 ltr rated at 99BHP but the MHEV with the 1ltr engine is rated at 119BHPso im not sure how the battery increases the power when the car isnt driven by a motor?

@@rpatel9901 It depends on which model year you're talking about. Before the MHEV engines, the regular engine as you say, was 100PS, but the newer MHEV engines in the later models are also 100PS. The 120PS engine, found in the N Line, has better tuning. So the power hasn't increased due to MHEV.

@@SGPetchLtd thank you for your reply so the i20 n line has just had the ECU tuned to increase its performance to 118BHP ( 120ps)
