Is America Ready for the Leaf?

In December of 2010, Nissan dealers will begin selling a new fully electric car called the Leaf. At a MSRP of $32,780 (not including delivery fees or taxes), the leaf will be the first affordable mass-produced fully electric vehicle. Tesla currently sells a high performance electric roadster, which costs over $100,000 making it an unsuitable choice for the average car shopper. However, by the end of this year Nissan will provide a larger demographic of car buyers with the opportunity to purchase an emissions-free plug-in electric car. With a 24 kWh Li-ion battery bank, the Leaf, on average, can deliver a 100-mile driving range per complete charge. Nissan claims the Leaf has a top speed of 90 mph and can accommodate five passengers.

Instead of going to a gas station to refuel, owners will have to recharge their car in a charging station that they must buy. Nissan claims that the average cost of installing a 220V charging station will be $2,200. Using the 220V charging station, it will take between 4 to 8 hours (depending current rating of charging station) to fully charge the Leaf. Nissan claims that a full charge will cost owners less than $3 on their electric bill and provide the mentioned 100-mile driving range.

The cost of electricity needed to operate the Leaf over a certain range is less the cost of fuel used in conventional IC engine cars and hybrid cars for the same range. It does not take a detailed mathematical analysis to show that unless the cost of gas is very high, a person will not save money by buying an electric car such as the Leaf. Cars like the Toyota Prius and Toyota Corolla are very fuel-efficient, and have MSRP’s of $22,800 and $15,193 respectively.

Shoppers looking to buy a “green” car will definitely include the Leaf in the list of cars they are considering. However, the financial incentive of purchasing the Leaf does not exist. Policy makers must take action to lower the price of the Leaf and make it an economically feasible substitute among other “green” cars. On a national level, the DOE will provide a $7,500 non-refundable tax credit to people who purchase the leaf. Additionally, a non-refundable tax credit worth 50% (capped at $2,000) of the cost of installing charging equipment is available. It is important to realize that that these tax credits have the potential to make the Leaf much more competitive. The word, potential, is emphasized because not everyone will be able to benefit from the full tax-credit they qualify for. For example, to benefit from the full $7,500 tax credit a single person must have a taxable income greater than $45,275. Additionally, to take advantage of both the tax credit for the car and the charging station a person’s taxable income will have to be even higher. Since these credits are non-refundable, the level of benefit someone receives is based on their taxable income. Since not everyone can fully benefit from the tax credit, the car becomes less competitively priced, thus decreasing the percentage of “green” car shoppers who can afford to buy the car. This is a big problem if market penetration of electric cars is important in the United States. California for example, will give residents a $5,000 purchase rebate for the Leaf. The rebate has nothing to do with taxable income and gives everyone the opportunity to receive the same savings. A $5,000 purchase rebate combined with the federal tax credit for the car has the potential to reduce the price of the Leaf by $12,500. If this savings is realized, the Leaf will suddenly become the best economic decision for shoppers and will create a high demand for electric cars. The future of electric cars is uncertain in the US, but the policy California has made may play a huge role in whether or not the Leaf is successful in the US.

Another obstacle for the Leaf worth mentioning is the fact that it has a limited range. This is a constraint owners of conventional IC engine cars do not have, and is one that electric vehicle owners will have to accept. The sole idea of not being able to make a long distance trip might make some shoppers hesitant to buy the car. Additionally, the need for an at-home charging station will reduce the number of “green” car shoppers that choose to buy the Leaf. If a person does not own a home with a garage, installing a charging station might be very inconvenient and may not even be possible.

GM Scheduled to Launch Chevy Volt in Novemeber

Currently, the Chevy Volt is undergoing cold weather testing in Kapuskasing Canada and is on track for the Nov 1, 2010 production date. The earliest consumers could take one home is estimated to be late November or early December. The release of this car is a very big deal for the automobile industry, consumers, and policy makers.

Aside from the luxurious Tesla roadster, the Chevy Volt will be the first mass-produced vehicle that uses an electric motor for its propulsion system. However, the Chevy Volt is still labeled as a hybrid-car by the Society of Automotive Engineers because it uses two energy storage systems to provide propulsion power. GM claims that this plug-in-car can travel an average of 40 miles without ever using a drop of gas in the car’s 1.4 liter 4-cyl flex-fuel (unleaded gasoline or E-85) engine. Unlike current hybrid vehicles, the internal combustion (IC) engine is only used when the battery is low. For the first time in the automobile industry the IC engine solely drives an electric generator that charges the batteries and powers the electric motor versus mechanically driving the wheels.

Why are the car companies switching from gas to hybrid-vehicles and now to electrically propelled vehicles? Improving fuel economy, improving emissions, and displacing dependency on petroleum are goals GM and other car companies are working to achieve. Above is a slide from a presentation by GMPT that describes the companies Advanced Propulsion Technology Strategy. The release of the Chevy Volt will represent a big shift up GM’s strategy curve. During the first 40 miles of operation the car will produce zero emissions because the IC engine will not be operating. Additionally, the possibility of completely displacing petroleum in the first 40 miles of operation exists depending on how the electricity the consumer used to charge the car was generated.

The next big question in everyone’s head should be cost. GM has not revealed a price but says it will be around $40,000. What would be the cost if you only drive the car less the 40 miles each day and charge it up overnight? The average U.S. electricity cost is 11 cents per kWh and the electricity needed to drive 1 mile would be 3 cents. This sounds very attractive but a price tag that is roughly twice that of the Toyota Prius does not make the Volt a good economic decision unless gas prices skyrocket. However, power companies and governments will be offering incentives to people who purchase these plug-in-vehicles. For example, buying this car would allow you to claim a $7,500 tax credit in the United States. Additionally,  Canada’s government has already committed to support GM and offset the cost of the car by purchasing 500 Volts which will be used as government-use vehicles and by giving Canadians rebates up to $10,000.

Finally, there is a lot of controversy of how to rate the fuel economy of this vehicle. GM claims the Volt has a 230 mpg rating in the city. However, this is very deceiving and will surely cause the EPA some headaches when they decide how to rate this car. Depending on how the accounting is done the fuel economy could be 1000 mpg. However here are two facts that you can use to decide what the miles per gallon rating is. On average after a full charge you will be able to drive 40 miles without the IC engine kicking in. After the IC engine kicks in you can expect 48 mpg. For example, if you drive 50 miles you will use approximately 0.2 gallons of gasoline, thus giving you a rating of 250 miles per gallon of gasoline. In other words the fuel economy will depend on the range of your drive and will decrease towards 48 mpg as the range you travel without plugging in increases.
