PSA Readies New Battery-Powered Models

PSA Group is developing two new lightweight, modular platforms that will carry a variety of electrified vehicles starting in 2019.

Designed for front- and all-wheel-drive C- and D-segment vehicles, the EMP2 (efficient modular platform) will be used for future Citroen, DS and Peugeot plug-in hybrids sold in China and Europe. PSA plans to launch the first plug-in model based on the chassis in 2019 with another six to follow by 2021.

The plug-in hybrid system will team a small gasoline engine (150-200 hp)—replacing PSA’s current diesel-electric system—with an electric motor for the front axle and a 12- to 13-kWH battery pack, which PSA says is 20%-30% more powerful than those used in current plug-in models. The carmaker estimates the hybrid system will have an all-electric range of 60 km (37 miles).

In what PSA describes as an industry first, the hybrid layout will positon an eight-speed transmission laterally between the engine and electric motor. A second motor would power the rear axle in awd powertrains.

The smaller CMP (common modular platform) design, which the carmaker developed with its Dongfeng Motor Group partner in China, will carry four new EVs due to launch in China and Europe between 2019 and 2021. PSA says the platform can handle everything from a small city car and compact SUV to B- and C-segment sedans.

The new EVs will feature a 50-kWh lithium-ion battery that provides a 450-km (280-mile) driving range. PSA says the battery can be charged to 80% of its capacity in 30 minutes with a 7-kW charging system.

The EVs also will get a more efficient heat pump the company says will significantly reduce energy consumption. PSA estimates the system will help boost driving range by as much as 50 km (31 miles).

The two new architectures allow for greater vehicle design flexibility in terms of length, width, height and wheel diameter, according to the carmaker. The platforms also are lighter: the EMP2 sheds 55 lbs from the first-generation EMP chassis that was launched in 2013, while the CMP saves 88 lbs over its predecessor.
