Hyundai develops first 48V hybrid diesel powertrain

The New Hyundai Tucson will be equipped with a 48V mild-hybrid powertrain. It is the first model in the company’s line-up to offer the new technology.

For the first time in a Hyundai, the New Tucson will feature a 48V mild-hybrid powertrain system in combination with a 2.0-liter diesel engine. The electrification technology comprises a 0.44 kW/h 48V lithium-ion battery, a mild-hybrid starter generator (MHSG), a low-voltage DC/DC converter and an inverter.

Under acceleration, the MHSG supports the engine with up to 12kW. The system will switch automatically between mechanical use of the engine and energy recuperation. The MHSG assists the combustion engine by discharging the battery to reduce engine load with light acceleration or to provide additional torque to the engine under strong acceleration. During in-gear deceleration and braking, energy is recuperated to recharge the battery.

In addition to the upgraded powertrain portfolio, all Tucson engines meet the new Euro 6d Temp emission standards. By spring 2019, the 48V mild-hybrid technology will be available with new the Smart Stream 1.6-liter diesel engine.

“With our new mild-hybrid powertrain system for our best-selling model, we are further expanding the company’s electrification strategy to make clean technologies accessible for even more customers,” said Andreas-Christoph Hofmann, vice president of marketing and product at Hyundai Motor Europe. “It will be available in combination with more engines in the future, as part of our highly diverse mix of electrified solutions.”

With this technology, Hyundai aims to reduce fuel consumption and CO₂ emissions by up to 7% combined with the manual transmission in NEDC conversion.
