Both will appear first in DS models and there will be a battery electric vehicle with a range of 279 miles.
The larger of the two, EMP2, will be used for C and D platform cars and the smaller CMP (common modular platform) will serve smaller B and C segments.
The EMP2 platform will include plug-in hybrids in both front-wheel drive and all-wheel drive formats.
The plug-in hybrids will be petrol-electric and PSA will phase out diesel hybrid technology when the new cars come on stream.
The new CMP-based electric vehicle will be powered by a 113bhp front-mounted electric motor powered by a next-generation lithium ion battery with a capacity of 50kWh. Its maximum speed will be 93mph.
Fast home charging is done via a 7kW onboard charger capable of delivering enough charge to create a range of 62 miles in 90 minutes. An ultra fast charging system delivers an 80% charge in 30 minutes, or 7.5 miles of additional range for every one minute of charging time.
The larger EMP2 platform will include a plug-in hybrid (PHEV) drivetrain as a superior solution for larger cars.
Saloon version will get a 12kW battery pack capable of delivering 80kW, while larger SUVs and CUVs will get a 13kWh pack with a power output of 90kW.
The capacity of the new batteries is 12 times greater than the company’s existing plug-in batteries.
The batteries can be charged in 4.5 hours using the standard home charging system and 2.5 hours if the homeowner has a 32-amp socket installed to power a 6.6kW charger.
Petrol engines will range from 147bhp to 197bhp, they are front-mounted and will be combined with a new technology eight-speed automatic transmission and a 108bhp electric motor.
Four-wheel drive versions will have an additional 108bhp electric motor mounted on the rear axle. The combined maximum total power available is 247bhp for two-wheel drive and 296bhp for AWD cars.
Range in all-electric mode will be 37 miles, which means for most drivers, the majority of journeys will be completed in battery-only mode.
