Nissan Leaf Winter Range Test: How Cold Weather Impacts Electric Vehicle Performance

Driving an all-electric car in summer or fall is one thing, but tackling a Canadian winter presents unique challenges. While gas-powered vehicles also see reduced efficiency in cold temperatures, the effect is far more pronounced for EVs. This year, winter arrived with a vengeance, putting the new Nissan Leaf to the test under freezing conditions.

Real-World Range in Cold Weather

During the Leaf's launch near Cobourg, Ontario, in late October, temperatures hovered around 7 to 8 degrees Celsius. However, a recent drive in near-freezing conditions highlighted the impact of cold on battery performance. The car, rated for 463 kilometres in warm weather at speed limits, achieved an average realistic range of 415 kilometres when driven at traffic speeds. This represents an approximate 11-per-cent drop.

Note: Without home charging, the tester could not utilize the Leaf's pre-warming features for the battery and cabin, which could have extended the range further.

Model Variants and Specifications

The new Leaf is available in three editions, all equipped with a 75-kilowatt-hour battery and a standard heat pump. The tested SV+ model starts around $50,000, positioning it as the mid-range option. The lighter S+ boasts a claimed range of 488 kilometres, while the heavier Platinum+ claims 417 kilometres. All variants share the same 160-kilowatt electric motor, producing 214 horsepower and 261 lb-ft of torque, with differences arising from weight, wheel size, and additional features that consume energy.

Interestingly, the weight variance among the three models is less than 29 kilograms. Like most EVs, the range is generally sufficient for daily driving but leaves room for improvement. A fourth edition, the more basic S model, is expected later this year, featuring a smaller 53-kilowatt-hour battery and a 130-kilowatt motor for a lower price and shorter range.

Pricing and Market Competition

With a starting price of $47,857 including freight and fees, the new Leaf is now one of the least expensive electric vehicles on the market. It competes directly with the Hyundai Kona, though it sits above the Kia EV4 and Chevrolet Bolt. The SV+ costs $3,000 more, and the loaded Platinum+ adds nearly $5,000 to that. This third-generation EV has undergone significant updates to stay competitive.

Charging Capabilities and Innovations

A key update is the inclusion of NACS charging ability, allowing the Leaf to charge at most Tesla superchargers. It features two separate charging ports: Level 3 NACS and CCS (with an adapter) on the right front fender, and Level 2 CCS on the left. This eliminates the need for outdated CHAdeMO stations required by previous models. The car can charge at up to 150 kilowatts on powerful Level 3 chargers, though the Level 2 port does not lock, meaning anyone can unplug it during slow charging.

The Leaf also integrates seamless charging through the MyNissan app, similar to systems by Porsche Canada for its EVs. When registered, the car can automatically charge at compatible stations without app interaction. However, during testing, a corporate credit card issue prevented this feature from working, highlighting a minor glitch in an otherwise convenient system.

Design and Interior Features

Externally, the new Leaf is attractive and inoffensive, with options like Seabreeze Blue two-tone paint for $795. Its streamlined shape improves aerodynamics, reducing the drag coefficient to 0.26 from the previous 0.29.

Inside, the cabin is well-constructed and accessible, with comfortable seats and ample space for adults in both rows. However, the lack of physical buttons posed a challenge; for instance, turning on the radio required using voice control via the steering wheel. This minimalist approach may appeal to tech-savvy users but could frustrate others.

Performance and Technology Assessment

Performance is respectable but not exhilarating, with no neck-snapping acceleration even in Sport mode. Technologically, the Leaf offers features like ProPilot driver assistance, though it functions similarly to standard lane-keeping and cruise control, requiring hands on the wheel every 10 seconds. Some glitches were noted, such as incorrect speed limit displays on highways and issues with Apple CarPlay integration.

The "e-Step" one-pedal driving allows for regenerative braking, adjustable via steering wheel paddles. Unlike many EVs, however, it does not bring the car to a complete stop and will creep forward without brake application, a limitation compared to competitors.

Cargo and Practicality

As a reasonably spacious electric crossover, the Leaf provides 566 litres of cargo space behind the rear seats, expanding to 1,572 litres with the 60/40 seats folded flat. There is no front trunk, but a clever hidden compartment under the trunk floor offers additional storage or acts as a divider.

Final Verdict

The third-generation Nissan Leaf represents a significant improvement over its predecessor, with enhanced charging options and competitive pricing. While software glitches and app issues were observed during testing, these are likely to be resolved. However, as the EV market evolves rapidly, the Leaf must continue to innovate to keep pace with newer competitors.
