PARIS — A new 48-volt mild hybrid system from Stellantis will debut on the Peugeot 3008 and 5008 SUVs in the second quarter, with CO2 emission reductions of up to 15 percent.
The mild-hybrid system is based on a 1.2 liter three-cylinder gasoline engine with 136 hp that is mated to a new dual-clutch six-speed automatic gearbox with an electric motor that Stellantis developed in a joint venture with Punch Powertrain.
An 898-Watt-hour battery is housed under the front left seat.
It will replace the 130 hp non-hybrid motor on the compact 3008 and midsize 5008. Peugeot says CO2 emissions will be reduced by 20 grams per km to 126 g/km on the 3008 and 128 g/km on the 5008.
The system will be launched on the 3008 and 5008 first, then be deployed throughout the brand’s range, including the small 208 and 2008, and the compact 308 and 408, Peugeot said this week. It is expected to also be available across other Stellantis brands, including Opel/Vauxhall, DS and Citroen.
At low engine speeds, a 21-kilowatt electric motor increases available torque and smoothes turbo lag during acceleration. During deceleration, the gasoline engine cuts out and the motor recharges the battery. It is possible to drive short distances using battery power only, and Peugeot says that more than 50 percent of urban driving can be zero emission.
Peugeot did not release prices for the mild-hybrid powertrain.
Automakers have been turning to mild hybrid systems to cut emissions at lower cost than a full-hybrid system since the late 2010s, and they offer other benefits such as taking stress off the engine for stop/start functions.
The eDCT transmissions, as they are known, will be built in Stellantis’ factory in Metz, eastern France, as well as in Italy at the Mirafiori complex in Turin, which is set to start assembly in the second half of 2024. Stellantis plans to build 600,000 eDCT transmissions annually at each site, some for mild hybrids and others for plug-in hybrids.
