Nissan Reveals Technical Upgrades for Next-Generation LEAF with New 3-in-1 Powertrain and Smart Thermal Recovery

Nissan has released new technical details of its third-generation LEAF, spotlighting improvements in maneuverability, thermal efficiency, and cabin refinement as part of the company’s ongoing LEAF Insights video series.

The new model is the first to adopt Nissan’s 3-in-1 electric powertrain, which is 10 percent smaller than its predecessor while delivering up to 160 kW (214 hp) and 355 Nm (261 lb-ft) of torque in select variants. “The all-new LEAF delivers a responsive, smooth and confident drive. All elements have been optimized to support efficiency,” said Richard Candler, Vice President of Global Product Strategy at Nissan.

Improvements in sound insulation and powertrain design contribute to a quieter cabin, with noise levels reduced by up to two decibels at urban speeds compared to the outgoing model. The relocation of the HVAC system under the hood, made possible by the compact powertrain, has also increased cabin space and contributed to a more open interior layout.

On the chassis side, the third-generation LEAF features a multi-link rear suspension with 66% increased lateral stiffness. Coupled with a more rigid body and Nissan’s CMF-EV platform, the changes aim to improve both ride comfort and vehicle agility. Despite the availability of larger 19-inch wheels, an upgraded rack electric power steering system enables a tighter turning radius of 5.3 meters—0.1 meters shorter than the previous model.

A key advancement lies in the thermal management system. Chief Vehicle Engineer Hiroki Isobe noted, “The top priority for our engineering team was optimizing thermal management and never wasting energy. We even capture the heat produced by the on-board charger to warm up the battery.”

This is enabled by a newly adopted thermal recovery system paired with liquid-cooled batteries, which recycles heat from the on-board charger to help maintain battery temperature and performance—especially beneficial in cold-weather conditions. The enhancement supports more efficient energy use and could contribute to extended driving range.

Together, the integrated updates across drivetrain, suspension, and thermal systems are expected to elevate the third-generation LEAF’s driving experience and operational efficiency.
