NISSAN LEAF

What's New for 2013

The 2013 Nissan Leaf receives a new 6.6-kW onboard charger that cuts charging times in half. There's also a new "B-mode" driving mode that increases regenerative braking during deceleration. Finally, Nissan has added a more affordable S model to the lineup.

Introduction

One of the first full-electric vehicles marketed to American buyers, the Nissan Leaf enters its third year of production with a handful of refinements that should keep it foremost in the minds of EV shoppers. Now assembled at Nissan's Tennessee plant, the 2013 Nissan Leaf features a new 6.6-kW onboard charger that can replenish the battery in about four hours using a 220-volt electricity source. That's about half the time it took previously.
The bigger news, however, is the introduction of the more affordably priced entry-level S trim level. With it, Nissan has made the Leaf one of the most accessible electric cars on the market. The S is not a bare-bones stripper model either, as it features power accessories, keyless entry, heated front and rear seats, Bluetooth and USB/iPod connectivity. The Leaf's older 3.6-kW charger is used here to keep costs down, but the new, quicker charger -- standard on the upper trims -- is an option.

Ford Focus Electric

Ford Focus Electric
















Ford started shipping the Focus Electric in May 2012, a full year-and-a-half after the Nissan LEAF went on sale. For those looking for a pure electric car, the availability of the Focus Electric finally provided a point of comparison. (Other models, such as the BMW ActiveE and Honda Fit EV are only available in limited numbers for lease. The Mitsubishi i, a subcompact, is not a fair comparison.)
The key questions in play: Did Ford’s cautious decision to lag behind the LEAF allow the company to offer a better EV? Or is its tardiness a sign of its lack of commitment to fielding a competitive electric car?
The most immediate distinction between the Focus Electric and the LEAF is in the looks department. As I pointed out in my New York Times review of the Focus EV, the LEAF’s “wide rear end, bulging headlights and odd proportions evoke a Japanese gizmo aesthetic that doesn’t necessarily appeal to mainstream American car buyers.” On the other hand, the electric Focus has the same handsome appearance as the gas-powered version. Focus Electric drivers are not likely to attract quizzical stares from passers-by.

The electric Focus is nearly identical to the gas version in appearance. One minor—but damn cool—tweak in the Focus’s body is the blue light that circles the fueling door on the left side, where you plug in the car. It shows charging progress at a glance from a distance by illuminating successive sections of what serves as glowing state-of-charge pie chart.

Critical Distinctions

In terms of core electric drive technology, the efficiency of the Focus Electric and the Nissan LEAF, and the resulting driving range, are essentially the same. According to official EPA ratings, The Focus Electric’s 23-kWh battery pack issues 76 miles of driving range on a single charge—while the LEAF’s 24-kWh pack dishes out 73 miles. That makes the Focus more efficient, but the difference is negligible—that is, until harsh summer or winter temperatures take their toll. In summer 2012, LEAF drivers in Arizona complained of a loss of battery capacity on extremely hot days.
But Ford opted to utilize an actively liquid cooled and heated battery pack allowing for stable battery operation over a wide range of temperatures. (The LEAF is passively air-cooled.) It might be a full year before we know if the liquid cooling makes a difference—but it should.

The Focus’s slightly better efficiency numbers do not come at the expense of performance. The Focus, in fact, employs a 107-kilowatt (143 horsepower) motor, compared to the LEAF’s 80-kilowatt (110 horsepower) motor. I especially felt the difference in power on the highway, as Ford tuned the Focus more for high-speed advantage, rather than for jumping quickly off the line. The Focus is also quieter than the LEAF. Ford engineers told me that they went to great lengths to reduce motor and road noise by adding sound damping.

Mitsubishi I-miev

THE URBAN
ENVIRONMENTALIST


Designed to inhabit cityscapes, the i-MiEV's 62-mile range3 is ideal for most commuters, featuring 3 drive modes (performance, efficiency or regenerative braking) to give you custom performance for your unique life and driving style. Along with responsive handling and a tight turning radius, it's easy to see how this urban dweller has become a true citizen of the globe.

MODEL OF EFFICIENCY:
112 COMBINED MPGe4



With an EPA-rated 112 miles per gallon equivalent, it's no wonder the i-MiEV was named "The Greenest Vehicle of 2012" by the American Council for an Energy-Efficient Economy. When you can drive for around 3.6 cents per mile7, you're behind the wheel of one of the most efficient electric cars on planet Earth.
