Peugeot Launches Mild-Hybrid Powertrain for 3008 and 5008

Peugeot has launched its first mild-hybrid powertrains claiming a 15% fuel efficiency for its 3008 and 5008 models.

The powertrain joins the automaker’s existing range of diesel, gasoline, PHEV, BEV and hydrogen fuel cell variants. This 48-volt system employs a new-generation 136bhp PureTech gasoline ICE coupled with a six-speed dual-clutch electrified gearbox that includes an electric motor.

With a battery that recharges while driving, this technology provides extra torque at low engine speeds and on top of fuel savings claims to lower CO2 from 126g of CO2/km on 3008 and from 128g of CO2/km on 5008. The automaker also says that, in urban driving, a C-segment SUV equipped with the system can operate more than 50% of the time in 100% zero-emission electric mode.

All the parts that make up this powertrain system are located under the bonnet, except for the 48V battery, which is installed under the front left seat. Its gasoline engine is a 1.2-liter three-cylinder gasoline unit claiming top power output at 5,500rpm and torque of 169ft-lbs from 1,750rpm. It employs variable geometry turbocharger for improved engine performance, a timing chain to reduce maintenance costs, Miller cycle operation for better combustion thermal efficiency and claims to meet Euro 6.e standards.

Its electrified section uses a permanent magnet synchronous electric motor, built into the gearbox, develops a peak power of 28bhp and a torque of 40ft-lbs. It allows the vehicle to be driven 100% electrically for low torque requirements and assists the combustion engine to reduce its consumption. During deceleration, the engine acts as a generator to recharge the hybrid system’s 48V battery. It also provides the main start for the combustion engine with the assistance of the belt-starter.
