One third of the energy produced by automotive drivetrains is today lost as heat through the exhaust system.
This heat is a valuable resource if it is captured and used in the vehicle. As a world first, Faurecia equips the all-new Hyundai IONIQ Hybrid and plug-in Hybrid with its compact Exhaust Heat Recovery System (EHRS), offering up to 3 % fuel savings, as measured on U.S. EPA Federal Test Procedure (FTP20). This energy recovery system is particularly well-adapted for use on hybrid vehicles, whose development is expected to soar over the coming years.
How the system works
Exhaust heat is recovered by a gas/fluid heat exchanger integrated in the exhaust line. Up to 3 kW of energy is transferred to the engine cooling system and is then used to warm both the engine and the cabin. This allows the hybrid vehicle to operate more often in electric mode, thus improving fuel economy and reducing CO2 emissions. Moreover, the carmaker can downsize or eliminate costly electrical auxiliary cabin heaters. Once the targeted coolant temperature has been reached, an actuated valve enables the system to be by-passed in order to avoid overheating the engine.
Faurecia solution offers up to 7% fuel savings
The Faurecia compact EHRS weighs less than 3 kilograms and offers best-in-class packaging, allowing installation in a position close to the engine for maximum heat recovery. It is the most competitive solution of its kind on the market and brings a reduction in fuel consumption of up to 7% due to faster engine warmup and increased use of the electric mode. Additionally, the technology is eligible for CO2 off-cycle credits of 1.5 g/mile in the U.S.A.
Faurecia has more than 10 years’ experience with energy recovery systems, having introduced its first generation of exhaust heat recovery systems in 2006. It is currently developing the next generation systems and has co-development projects with its customers for its Exhaust Heat Power Generation (EHPG) system and Thermo-Electric Generator (TEG). These systems make it possible to convert exhaust heat into mechanical or electrical power and are expected to be on the market from 2020.

The IONIQ is Hyundai’s advanced, alternative-fuel compact vehicle launched on March 1, 2016 while the IONIQ Hybrid variant is the first to come to market. It is equipped with a newly developed 1.6 GDI four-cylinder engine and a 32kW (43.5PS) electric motor powered by an advanced Lithium-Ion polymer battery.
Faurecia is one of the world's largest automotive equipment suppliers with four Business Groups: Automotive Seating, Emissions Control Technologies, Interior Systems and Automotive Exteriors. In 2015, the Group posted total sales of € 20.7 billion. At December 31, 2015, Faurecia employed 103,000 people in 34 countries at 330 sites and 30 R&D centers. Faurecia is listed on the NYSE Euronext Paris stock exchange and trades in the U.S. over-the-counter (OTC) market. For more information, visit: www.faurecia.com
