2025 Peugeot 408

PureTech

1.2L Turbo I3 Mild Hybrid

A 136 hp three-cylinder turbo running a Miller-cycle combustion strategy, with a small electric motor in the gearbox filling low-rev torque gaps for seamless, lag-free pull. It can creep and manoeuvre on electric power alone at low speed.

A new generation of Stellantis's award-winning PureTech three-cylinder, specially reworked for hybridisation and introduced on the 3008 and 5008 in 2023. It pairs with a purpose-built electrified six-speed dual-clutch gearbox (e-DCS6).

• The earlier turbo PureTech 1.2 family won the International Engine of the Year award in its class four years running from 2015.
• The 48V mild-hybrid system recharges on the move and can cut fuel use by up to around 15%, with the electric motor housed inside the dual-clutch gearbox.
• It runs a Miller combustion cycle with a variable-geometry turbo to improve thermal efficiency.
