e-HDi micro-hybrid technology

After the 508, the new Peugeot 308 is the second of the Marque's cars to introduce the innovative e-HDi micro-hybrid technology, a new generation STOP & START.

This innovation is based on the combination of a 1.6 litre HDi Euro 5 diesel engine and a reversible alternator ensuring the STOP & START function. Relying on an alternator control system (Volt Control) to recover energy during deceleration and a hybrid battery to store and deliver additional energy on startup (e-booster), the HDi unit allows:

a 15% reduction in fuel consumption in urban traffic;
a 5 g/km reduction in CO2 emissions for approved cycle fuel consumption;
40% faster restarting (400 ms) than with an enhanced starter STOP & START;
activation of engine cut-out from 20 km/h with a manual gearbox (8 km/h for the electronicallycontrolled gearbox);
increased driveability of the STOP & START (silent operation, no vibrations).

The second-generation reversible alternator used here has a power of 2.2 kW and allows up to 600,000 restarts. However the STOP & START function can be de-activated by the driver if preferred by means of a button on the fascia panel.
