Nissan believes its purely electric Leaf car, not hybrids, is the way of the future

The greenest of all?

Photographs BY Colin O’Connor

At a recent automotive conference in Detroit, Nissan Americas chairman Carlos Tavares hoisted a large car muffler over his head and then accused Nissan’s competitors of misleading people when it comes to electrically powered vehicles. “If you’re calling your car electric and it has one of these,” he said, waving the auto part. “You’re only muddling the message.”

Though sales of electric or hybrid electric vehicles represent a tiny fraction of the overall market, automakers aren’t pulling any punches when it comes to talking up their newest creations. The nascent segment, which automakers have pumped many billions of dollars in research and development into, is fast becoming one of the most competitive. But the rush to go green has created an unintended consequence: consumer confusion. Each automaker has come up with its own take on the electrified car of tomorrow, a category that also includes hybrids and plug-in hybrids—both of which incorporate a gasoline engine. And nobody wants to get stuck with a four-wheeled equivalent of a Betamax in the garage.

For its part, Nissan is betting the future won’t involve gas stations at all. Its compact Leaf electric car, the result of US$6 billion in research and development that began in 1992, is touted as the first-ever mass-produced electric vehicle, and is priced to compete with cars powered by conventional engines (it costs about US$32,000 in the United States before government incentives, which can bring the sticker price down to around US$20,000). “That’s why we went to Detroit with a muffler,” Tavares said during a recent interview with Maclean’s in Toronto. “We wanted to explain to people visually that when you have a zero-emissions car, you don’t have a tailpipe—because there is no gas.”

The Leaf goes on sale in Canada later this year, although prices haven’t yet been announced. It looks like a regular compact until you pop the hood. Underneath is a virtually silent engine (engineers actually added a noise at low speeds so pedestrians can hear it coming). The direct-drive motor draws power from a table-sized battery hidden beneath the seats that gives the car a range of around 160 km on a single charge. The Leaf handles not unlike a Toyota Matrix, albeit with a bit more pep off the line. In exchange for never having to visit a gas station, Leaf owners are asked to pay roughly $2,000 to install a charging station in their garages, which can complete a full charge in seven hours—essentially overnight. “Ninety-five per cent of people drive less than 100 miles per day,” says Tavares. “It’s a fact. For anyone that commutes and lives in the suburbs of big cities, it’s the perfect car.”

Of course, Nissan’s competitors beg to differ. Toyota has already staked out its territory with its 10-year-old Prius hybrid, betting that people are mostly looking for better fuel economy (the Prius is basically a regular car with an electric engine that takes over periodically, after harnessing energy from the brake systems). Meanwhile, GM has put its money in its plug-in hybrid Volt car (US$41,000 before government incentives), which runs off its battery for the first 56 km before a gasoline backup engine kicks in to power an on-board generator. GM claims this eliminates the “range anxiety” of pure electric vehicles (which can’t stop at a gas station for a quick fill-up), a point hammered home in a recent Volt ad that plays up the unpredictability of life on the road. So far, the message appears to be resonating with early adopters. In January, General Motors says it sold 321 Chevrolet Volts in the U.S. while Nissan has sold just 87 Leafs.

Tavares, however, says the endgame is pure electric—he calls hybrids and plug-in hybrids “transition” technologies—and points to recently unveiled concepts such as Ford’s Focus electric as evidence its rivals are already coming around. In fact, Carlos Ghosn, the CEO of Nissan-Renault, has forecast that electric cars will comprise 10 per cent of the market by 2020, with Nissan comfortably in a leadership position.

But observers remain skeptical. “That seems pretty lofty,” says Mike Wall, an auto analyst at consultancy IHS Automotive. He notes that fuel efficiency of conventional cars continues to improve and that the price of electric vehicles remains comparatively high. “Consumers haven’t all of a sudden forgotten about prices,” he says.

Tavares, however, likens it to the shift to mobile phones, which went from being a niche gadget used by businessmen to widespread adoption seemingly overnight. “The trigger for the mass market is when you shift from early adopters to pragmatists,” he says, adding that the cost of charging a Leaf is only about $2.50. “And pragmatists will make the calculation that, the higher the oil price, the bigger the savings will be.”

    Yes all you people in Ontario buying an electric car in a province run by an insane Premier who is now buying "green power" back from people who he gave subsides to, to put solar panels on their roofs and pay them 80 cents a k/hr. should feel good about all this as your power rates rise by 50% in the next few years. So not only will you be paying though the nose to heat and light your home you can do the same to run your car. I hope applying make believe solutions to non-existent problems gives you a warm fuzzy feeling as you become energy poor. Cheers.

      I really feel sorry for people like you. I suppose living with no conscience and a complete lack of regard for other people is fine with you, but I appreciate people who realize what is at stake for my young children

        Your children could emigrate to China and become Unicorn ranchers in their environmental utopia after Liberals tax your kid's employment prospects into oblivion while at the same time raising taxes…..

          Do yourself a favour and read a book, just because Tubby and the Trool say stupid things, doesn't make them true. What happens when China and India have consumption rates approaching western levels? I guess you prefer to live in a fantasy world that doesn't extend beyond your own backyard.

        Are you the same person who made the original comment or do you two just have eerily similar names?

        Electric cars are great and I'm glad more ocmpanies are getting competitive about them. I hope charging stations become more common as well, so that people could take them on longer drives outside the city.

  • Philanthropist

    I hope lots of people buy these cars, it would make commuting so much easier when all those people are taking the bus. Dalton McGuinty is damaging the environment by wasting huge amounts of Ontario's resources on systems that don't provide power – systems that also damage the environment themselves. He picks up a few votes from the stupid, which is good for him only, it is certainly not good for the future of Ontario.

  • DT in GT

    Yes, let's trade gasoline powered cars for coal powered cars because it is so much better for the environment.
    Coal powered?
    WTF?
    50% of US electricity and almost 70% of China's is generated by coal powered plants.
    It is the same for India; about 70% from coal.

    • Stewart_Smith

      The numbers in this case are kind of interesting. A relatively modern coal fired electricity plant can apparently produce a kW-h of electricity for less than 1 kg of CO2. A car like the Leaf will probably use about 10 kW during operation… so to drive for an hour would produce 10 kg of CO2 (assuming it was generated by coal)

      Now if the Leaf was gas powered, it would get great economy so to drive it for an hour would likely use a little over a gallon of fuel. Each gallon of fuel in a well tuned engine produces about 10 kg of CO2.

      So a case can be made that a coal-electricity operated car is better for the environment than an internal combustion engine, although just barely. More telling is that in both cases CO2 is about the most benign emission. However, because coal fired plants operate hotter, and can invest in much more sophisticated emission controls than is possible in a car, the coal-electricity definitely wins. The aggregated costs associated with carbon monoxide, nitrous oxides etc coming out of car tailpipes is huge.

      • EeeOar

        Did you assemble those numbers yourself? If so, kudos.

        You're welcome to supply some links if you are so inclined, although I'm not actually doubting your numbers at all.

        • Stewart_Smith

          I pulled the numbers from all over… didn't find anyone who did it quite exactly right. For the CO2 emission from power plants http://www.eia.doe.gov/cneaf/electricity/

          CO2 emissions from tailpipes: http://www.epa.gov/oms/climate/420f05001.htm

          Estimated the power usage of the Leaf from its published battery capacity and range.

          The CO2 emissions from tailpipes is just that, a best case evaluation of what literally comes out of the pipe. i.e. it is not a lifecycle analysis. My recollection is that the coal fired plant was a life-cycle analysis and presumably made some assumptions about the source of coal. Correcting those would skew the results further towards the Leaf.

          Of course, the primary motivation behind all of this was to legitimately say "Leafs win!" for perhaps the last time in my generation.

          • EeeOar

            Thanks for those links.

            Mostly I commented because the type of synthesis that you did there is, unfortunately, very rare. I prefer that over regurgitated talking points, but maybe that's just me.

            Of course, the primary motivation behind all of this was to legitimately say "Leafs win!" for perhaps the last time in my generation.

            Sweet! But sn't it also the first time in your generation?

  • Ariadne

    They make it so difficult to visit other provinces or states with this car eh! So much down time for charging. What you save in gasoline will be spent plus more in hotel stay.

    • NewDaddy

      These are mostly commuter and metropolitan area travelers, not long distance cars. For that it might be easier to take the family's second car or rent one for the weekend, take the train or a plane. Then again some people may actually enjoy it and discover more of Canada that way, eh!

    • Lemonaid

      If the Ontario government follows through on its commitment to build battery-swapping stations (EV mobility service provider Better Place) then this range issue won't be a concern. Early adopters of EVs will use their vehicles for short-range daily trips. As, the demand for vehicles in Ontario shifts away from internal combustion engine vehicles and towards EVs, gas stations will be phased out for battery-swapping stations.

      There is also talk that there will be different charging options at public charge spots. A fast charge will top up your battery to 80% of its capacity in 15 minutes, while a standard charge will take a couple hours. This is of course in comparison to the slow charge at home of 7-8 hours.

  • Philip

    The major problem for electric cars in Canada right now is how our cold climate affects current batteries and their range.
    A range of 160 km on a full charge in the summer can drop to 30 km at -15. A battery warmer will just add to the drain, as will heating the cabin, defrosting windows, power accessories, the vehicles computers, etcetera…

    It’s a shift in the right direction, but full electrics aren’t quite ready for Canada yet.

    • Stewart_Smith

      I agree, and any reasonable estimate of the cabin heating & defrosting essentially doubles the power usage. These are warm weather vehicles.

  • Judge Roy Bean

    More coal and higher surcharges for home hydro consumers are just part of the equation not factored in. The range is pathetic. Too bad it isn't possible to carry a portable generator if you do get stuck. There are no asy solutions depite what the living-in-a-drreamworld lefties wanna tell you. Then there is the Al Gore type who are just plain liars, grabbing over a hundred million for himself feeding you bull***t.

  • chet

    Fly over Canada, from Toronto to Vancouver on a clear day.

    Look down every few minutes or so.

    Guess what you'll see. "Greenspace" as far as the eye can see.

    Those who live in cities generally assume because their tiny world is full of cars, that THE world is full of cars. From bumper to bumper, just like they see every day (much like some Amazon tribes that can't process long distances because their entire world is in the jungle).

    Moving past the junk science that is AGW theory,

    that Canadians of all people, living in a wilderness filled country, would seek to alter their economies for this movement (which to date has brought none of the vast periods of prolongued of warming it promised us in this frigid climate, barely sustainable for human habitation),

    is more evidence AGW is a religion beyond anything else.

  • chet

    "The basic problem with the battery powered car is the cold"…

    Get that everyone.

    We are supposedly burning in a firey inferno of global warming caused by our cars, giving rise to the need for electric "green cars"….

    except its far too cold.

    Layers.

  • JimD

    I can't believe the amount of idiots that still think CO2 is harmful. Get a life. Have you not heard of Piers Corbyn?

    • harebell

      Yes I have and not just the cherry picked bits either.

      Corbyn has been claiming that this would be the coldest winter evah for about 5 years now. (A particularly spectacular balls up was recorded in 2008.) And just like the "The end of the world is nigh" dudes one of them will be right one day and he lucked out this year in the UK. That still makes him less successful than a broken clock.
      Most of his criticism now doesn't even come from his opponents but from fellow denialists who recognise just how wrong he is.

      As for CO2 being harmful, a high percentage of CO2 stored in the blood affects the ability of the blood to absorb the oxygen we need and reduces the amount of oxygen available to us to use. It also bumps up the pH making the blood more acidic. This can cause a loss in bone density because of the mobilisation of Calcium as a counter. So CO2 might be a huge issue for the elderly and women with osteoporosis problems.
      Oxygen can also be poisonous and too much water can kill you too. "All things are poison and nothing is without poison, only the dose permits something not to be poisonous."

    Generally, I agree with the article. Pure, battery-powered electric vehicles are the key to reducing GHG emissions in Ontario’s transportation sector (which currently accounts for one third of our total emissions). Hybrids with back-up gasoline generators do not effectively cut the tie between oil and mobility, and therefore, will likely not be part of a sustainable transportation network in the future. They can however, as the article suggests, act as a transformational technology, facilitating the shift from internal combustion engine (ICE) vehicles to EVs.

    With the current rebates (upwards of $10,000 for battery-powered EVs) and incentives in place for EVs (access to car pool lanes and charging spots in parking lots), the Leaf should be cost competitive with traditional ICE vehicles in Ontario. Factor in savings in fuel costs and maintenance (EVs have fewer moving parts and are thus, less prone to mechanical problems) and any remaining price differential should be minimal. Therefore, I don’t really see cost being a deterrent to Leaf sales in Ontario.

    The Leaf’s per-charge range of 160 km is also equivalent to most other pure, battery-powered EV models currently being manufactured. Given the relative density of the Greater Toronto Area, I’d say that range anxiety won’t be a significant factor that prevents commuters in the GTA from making the switch to EVs.

    To me the major stumbling block is the infrastructure. Ontario has partnered with Better Place to deploy an EV charging network, equipped with charge spots and battery-swapping stations. While the technology seems to be there (we’ll know for sure within the next year, as Better Place Israel begins its operations), no plan or timeline for the deployment of a provincial system has been released. It’s a classic paradox. What comes first, the chicken or the egg? Will the provincial government and Better Place invest in charging infrastructure without a guarantee Ontarians will purchase EVs and use it? IAt the same time, vehicle owners will be less inclined to switch to EVs without a reliable in place to guarantee they can charge their cars while they are away from home.

    I think the success of the Leaf and other battery-powered EVs in Ontario hinges on this infrastructural component. The sooner the infrastructure gets installed, the sooner we can start achieving deep cuts in GHG emissions from the transportation sector.
