First off, this is not the LEAF we’ve grown accustomed to seeing on the road since the model’s introduction in 2010. Our drive of the new generation 2018 Nissan LEAF quickly reinforced this is a whole-new animal, a new generation of the venerable electric car intended to capture the imagination and, not coincidentally, market share in the increasingly competitive electric vehicle field.
We have history with the LEAF. Green Car Journal first experienced the original LEAF’s capabilities in a technology demonstrator designed to share what Nissan had in mind for its groundbreaking, soon-to-come production electric vehicle. At Nissan’s behest, we tested the automaker’s LEAF-destined electric drivetrain in its EV-12 test mule back in 2009 at Nissan’s global headquarters in Yokohama, Japan. We later witnessed the LEAF’s unveiling, clearly showing Nissan’s willingness to push the envelope for electric cars with an edgy design.
We were impressed. So much so, in fact, that Green Car Journal honored the LEAF with the magazine’s 2010 Green Car Vision Award™ in Washington DC, ahead of its introduction to the market. Nissan’s insight into what electric vehicle buyers desired has indeed proved visionary over the years. Testament to this is the LEAF’s standing as the world’s leading affordable, mass production EV since its launch.
The all-new generation Nissan LEAF aims to expand on this success with new styling and a 50-percent increase in driving range. It also features a full suite of Nissan Intelligent Mobility technologies. This all-electric model is more attractive with excellent aerodynamics that result in a low 0.28 drag coefficient. Improved aerodynamics not only means a quieter ride but also contributes to greater range. That’s an important consideration in electric cars with near-silent drivetrains that don’t mask outside noise.
The new Leaf features a 150-mile driving range between charges compared to the previous generation’s 100 miles. This is an important milestone that serves to overcome potential ‘range anxiety.’ Why 150 miles rather than shooting for the 200+ mile range like the Chevy Bolt EV and Tesla Model 3? It’s all about balancing price with functionality. Simply, Nissan aimed at providing an affordable price point under $30,000 for the LEAF. That meant delivering the range it figured would fit the driving needs of most drivers while keeping battery costs within reason. It’s a sound strategy.
A more powerful 40 kWh lithium-ion battery pack features improvements and revised chemistry that bring a 67 percent increase in energy density. Nissan designers have located the low-slung battery pack and other heavy components to the middle of the chassis to enhance the car’s center of gravity and handling. Fun fact: Using vehicle-to-home systems, the LEAF’s battery can store a home’s surplus solar energy while parked during the daytime and use it to help power a home in the evening.
LEAF’s electric powertrain features a 147-horsepower electric motor that’s well-suited to the model. It provides 38 percent more horsepower than the previous version with 26 greater torque for improved acceleration. Acceleration is crisp with more than enough power at the ready for all the driving situations we encountered on twisty roads and Interstates. Intelligent Ride Control delivers more precise motor torque control during cornering. This also reduces vibration while improving ride quality and steering control. Electric power steering software has been tweaked for improved steering feel. The LEAF’s steering torsion bar is also stiffer for better feedback and more linear response to steering inputs.
Nissan’s e-Pedal slows down the car via regenerative and friction braking when a driver’s foot lifts off the accelerator. This delivers electricity to the battery while essentially providing braking force without using the car’s brake pedal. It even brings the car to a complete stop. We found that driving with e-Pedal kept our LEAF tester in place while stopped on a steep hill without requiring a foot on the brake pedal. Notably, e-Pedal allows drivers to go without using the brake pedal 90 percent of the time.
LEAF’s ProPILOT cruise control conveniently maintains a constant distance to the vehicle ahead. If that vehicle stops, ProPILOT automatically applies brakes to also bring the LEAF to a full stop. It remains stopped even with your foot off the brake. Driving resumes when ProPILOT is activated with the touch of a switch or light pressure on the accelerator. The system also helps keep the LEAF centered in its lane at speeds between 19 and 62 mph. Other LEAF driver-assist technologies include Intelligent Lane Intervention, Lane Departure Warning, Intelligent Emergency Braking, Blind Spot Warning, Rear Cross Traffic Alert, and Intelligent Around View Monitor with moving object detection.
The new LEAF’s interior has a more luxurious and high-end look. Its dashboard is dominated by a seven-inch display for infotainment and the navigation system, if so equipped, plus Nissan's Safety Shield state-of-charge and power gauge. Another seven-inch screen faces the driver in place of conventional dials. Apple CarPlay and Android Auto are included on LEAFs with the higher-spec infotainment/navigation system.
Today’s electric car market is different than that of the past. There are more choices in a growing number of vehicle classes and this makes it tougher for automakers to compete. Nissan aims to not only compete in the electric car field but dominate globally as it has in recent years.
The LEAF’s status as a true world car is underscored by widespread availability like the previous-generation LEAF. It’s also reinforced by Nissan’s global manufacturing capabilities with assembly plants in Japan, England, and in Smyrna, Tennessee. Offering the all-new LEAF at a base price of $29,990 here in the U.S. is a strategy that should bode well for Nissan in today’s increasingly competitive electric vehicle market.
