PSA Peugeot Citroën unveils new technologies and design innovations
At the Innovation Day PSA Group has presented a number of new technologies and innovations, including the VéLV electric concept, the EMP2 modular platform, the Hybrid Air system and new solutions for fuel efficiency.
PSA’s Innovation Day technological showcase introduced innovations aimed at facing challenges such as urbanization, climate change, consumers’ shifting mobility choices and new ways of using vehicles.
First introduced in 2011, the VéLV Concept is a compact three-wheeler with a range of 100 km and is homologated for use on all roads, including motorways. It is developed by PSA Peugeot Citroën in collaboration with French environment and energy management agency ADEME.
The concept is 2.81 m long, has a capacity of 3 seats, and weighs under 700 kg. The electric powertrain features a 20 kW (DC)/30 kW motor that allows to reach a top speed of 110 km/h.
The 8.5 kWh battery enables a driving range of 100 km, with an electric consumption of only 85 Wh per km).
The materials used are suitable for small-scale production solutions and include an integral one-piece body made of fiberglass and polyester resin, ABS PMMA self-colored thermoformed body panels, with a front end and door frames made of aluminum profiles.
The innovative Hybrid Air technology is a full-hybrid solution that combines a gasoline engine, a compressed air energy storage unit, a hydraulic pump/motor unit and an automatic transmission.
An intelligent electronic management system adapts the operating mode to the user’s driving style and optimizes energy efficiency.
The hydraulic components (motor and pump) recover and store the energy generated by:
- The internal combustion engine operating at top efficiency.
- Braking and deceleration (kinetic energy).
A specific continuous transmission ensures optimal use of the different energy sources depending on the type of driving in three operating modes: gasoline-only power, Air-only power (with the hydraulic motor alone transmitting energy to the wheels via the accumulators) and combined power.
The main advantages of this solution compared to other hybrid system is its affordability.
The Hybrid Air system allows to achieve fuel savings of 45% in city driving and is planned to be introduced on B segment (82 hp gasoline engine) and C segment (110 hp gasoline engine) models, as well as light commercial vehicles.
EMP2 (Efficient Modular Platform 2)
EMP2 is PSA Group’s new global modular platform, which will provide the basis for a wide range of body styles across several segments, tailored to different global markets.
These include four and five door sedans, station wagons, MPVs, notchbacks, SUVs, cabriolets and coupés.
From a technical perspective, the EMP2 will allow for a variety different combinations:
- Four different track widths, five wheelbases, two cockpit and cowl solutions
- Two rear suspension architectures (deformable beam and multi-link) and a variety of rear-unit modules for different versions (short, long, five or seven seats, independent or bench seats, internal combustion engine or hybrid, etc.).
- Increased manufacturing flexibility, notably at the body-in-white stage, allowing for up to six rear unit versions on a single line.
Operational in 2013, the new generation EMP2 platform is scheduled to gradually replace the PF2 and PF3 existing platforms by handling new C and D segment launches and is expected to cover half of Peugeot and Citroën vehicle sales worldwide.
Eco Hybrid: an accessible hybrid solution
The use of this technology on petrol and diesel vehicles in the B, C and D segments will reduce CO2 emissions by 15g and cut fuel consumption by up to 15%.
Dedicated Exhaust Gas Recirculation System (EGR):
EGR is an innovative solution to optimise petrol engine fuel consumption This innovation is designed to improve petrol engine efficiency and deliver significant fuel savings.
Hydole: a mainly electric hybrid demonstrator
The Group and its partners have developed a plug-in hybrid demonstrator that puts peace of mind into the EV driving experience to test the potential uses of the car of the future and meet customer expectations for driving range, comfort and affordability.
