Manufacturers have no choice.
To reduce the CO2 emissions of their ranges, the electrification of engines has become essential.
This is how at Stellantis, after having developed the plug-in hybrid and the electric, we are working on 48 V micro-hybridization. Peugeot is responsible for inaugurating this new powertrain developed by the equipment manufacturer Punch Powertrain.
It is based on the 3-cylinder 1.2 liter PureTech which has been completely redesigned to accommodate the 48 V light hybridization. This engine, which must meet the requirements of the Euro 7 standard, adopts the Miller cycle, a turbo variable geometry and a timing chain, instead of the wet belt.
This 3-cylinder has gained six horsepower to deliver 136 horsepower at 5,500 rpm and an identical torque of 230 Nm,
This block is associated with an unprecedented 6-speed dual-clutch automatic transmission specially developed to house a 28 hp and 55 Nm of torque electric motor in its housing.
The 48 V battery, placed under the left front seat completes the device.
Result: this light hybridization engine allows the two SUVs 3008 and 5008 which inaugurate it to reduce their consumption by 2.5 l/100 km in the city thanks to the numerous electric operating ranges, in particular during deceleration phases at approaching a traffic light or a stop sign.
On the road, consumption would drop by 0.7 l/100 km.
This translates into a 20g/km reduction in CO2 emissions.
The Peugeot 3008 Hybrid thus displays CO2 emissions of 126 g/km while the 5008 Hybrid is homologated at 128 g/km.
