e-HDi Micro Hybrid


e-HDi Micro Hybrid Technology

Also known as micro hybrid technology, Stop and Start, Peugeot’s e-HDi technology switches the engine off when you’re stopped at traffic lights or stuck in a jam. It then automatically restarts the engine when you need to move off.

This latest innovation, which delivers improvements of up to 15% in an HDi engine’s fuel efficiency and CO2 emissions, is available on the Peugeot 508 and 308.

The e-HDi system’s unrivalled performance reflects the forward-looking combination of several technologies:

    • A 1.6ltr HDi EURO 5 compliant diesel engine delivering 82kW of power at 3600 rpm and 270 Nm of torque at 1750 rpm - one of Peugeot’s most efficient powerplants.
    • A STOP & START system with a second-generation reversible starter-alternator (i-STARS - Starter Alternator Reversible System supplied by Valeo).
    • An e-booster system, for instantaneous engine restart.
    • An electronic alternator management system, for regenerative braking.
    • A gearbox with optimised gear ratios.

The defining characteristic of e-HDi is the stop & start technology which restarts in 400 milliseconds (twice as fast as a manual key start), is completely transparent to the driver, with no noise or vibrations and has a broad operating range.
