2023 will be a real electric year for Peugeot, presenting new models and technologies in the range. These include the new hybrid system developed by Stellantis, which will initially be offered on the Peugeot 3008 and Peugeot 5008 before being extended to other models. It complements the range of electrified engines, including plug-in hybrids, electric motors, and fuel cells.
The 48V hybrid approach consists of a new-generation PureTech petrol engine with 100 kW (136 hp) coupled to a new electrified six-speed dual-clutch transmission, including an electric motor. With a battery that charges while driving, this technology offers extra torque at low revs and decreases fuel consumption by up to 15%.
The Peugeot i-Cockpit informs the driver about how the hybrid system works. The different modes can be activated automatically. In everyday driving, the combustion engine and the electric motor work together or separately to optimize energy consumption. Under heavy acceleration, the electric motor provides the gasoline engine with additional torque at low revs. When decelerating, the petrol engine switches off, and the electric motor becomes a generator to charge the 48-volt battery. The vehicle only drives in the city for short distances and when maneuvering with the electric motor in "Zero Emission" mode.
Up to 15 percent less fuel consumption and 126 grams of CO2 per km for the Peugeot 3008 and 128 grams of CO2 per km for the Peugeot 5008 are two advantages of the new technology. Compared to a non-electrified petrol engine with comparable characteristics, the hybrid engine offers an average fuel savings of around 1 liter per 100 km (according to the WLTP cycle combined) in a C-segment SUV.
These savings are achieved in the city (minus 2.5 l/100 km) and on the country road (minus 0.7 l/100 km), while highway consumption remains unchanged. The performance means for the Peugeot 3008 and the Peugeot 5008 an average reduction in CO2 emissions of 20 g/km (combined according to the WLTP cycle).
If the battery charge allows, the hybrid system enables starting, maneuvering and low-speed driving in heavy traffic in all-electric mode. In the city, the Peugeot 3008 and Peugeot 5008 can be driven more than 50 percent of the time in zero-emission electric mode. At speeds up to 145 km/h, the combustion engine switches off if the driver does not press the accelerator pedal at a constant speed or when braking.
When accelerating, the electric motor provides additional torque with a single boost, compensating for the turbo's response time. This avoids and ensures more driving comfort and dynamics. When the accelerator pedal is fully depressed, the electric motor provides an additional 9 kW (approximately 12 hp) of power.
All the parts that make up the new engine are under the hood. An exception is a 48-volt battery installed under the left front seat of the Peugeot 3008 and Peugeot 5008.
The engine of the Peugeot 48V Hybrid features a new electrified six-speed non-torque-interrupting dual-clutch transmission specially designed for hybrid systems. The transmission case also houses the electric motor, inverter, and control unit, optimizing the vehicle's size and weight and guaranteeing excellent driving performance.
The electric motor built into the gearbox develops a peak output of 21 kW (28 hp) and a torque of 55 Nm. It enables the vehicle to be driven 100 percent electrically with low torque requirements and supports the combustion engine in reducing its consumption. When decelerating, the engine acts as a generator to charge the hybrid system's 48-volt battery. It also uses the belt starter generator to start the combustion engine. The starter, fed with 48 volts, ensures the combustion engine starts up again via the ancillary unit belt. It enables quick and transparent starts.
The 48-volt lithium-ion battery is designed to maintain the same performance throughout the vehicle's life and comes with an eight-year original warranty and 160,000 delivered kilometers.
The Peugeot 3008 and Peugeot 5008 have two electrical networks: a low-voltage network at 12 volts to supply the vehicle equipment and a high-voltage network at 48 volts to supply the hybrid system. The electricity is generated exclusively by the 48-volt electric motor. A DC-DC converter transfers the electricity generated to the vehicle's 12-volt network.
The Peugeot models equipped with the new hybrid engine have a unique display. The digital display shows the energy flow in the system, battery charge level, operating status via a power meter (Charge, Eco, Power), and percentage of distance traveled in electric mode at any given time or date end of the journey.
In addition, these models will be equipped with the AVAS (Acoustic Vehicle Alerting System), which will cast a sound at speeds of up to 30 km/h to alert pedestrians and cyclists that the automobile is approaching.
