Chevy Volt FAQs
Q: What is the Chevy Volt?
A: The Chevy Volt is an extended-range electric car being developed by General Motors. It currently exists in prototype form only but GM reports they are fully committed to bring the car to production. In June 2008, GM’s board of directors voted to fund production of the vehicle, and in September 2008 the production version was unveiled.
Q: How is the Chevy Volt different than other cars on the road?
A: The car is a plug-in range-extended electric vehicle with an on-board gasoline generator. It will have a large battery that stores power from your home electric outlet and which is connected to an electric motor. The electric motor directly propels the car. The battery can last for the first 40 miles. After that, should one continue to need to drive, the on-board gasoline/E85 generator will power up to keep the battery from running out.
Q: How is the Chevy Volt different than today’s hybrids, like the Prius?
A: Today’s hybrids are called parallel hybrids. They use a small electric motor for low speed driving, but switch to a regular gas engine for acceleration and faster speed driving, hence both engines work side by side or in parallel. The Volt is a series vehicle meaning only the electric motor power the car at all times, the gas engine is just a generator, making electric to keep the batteries in a steady state of charge.
Q: What is the driving range of the Chevy Volt?
A: The car is being designed to drive at least 40 miles on pure electricity stored in the battery from overnight home charging. After that the gas engine will kick in and allow the car to be driven up to 400 miles on a full tank (6-7 gallons) of gas.
Q: How many miles per gallon will the Chevy Volt get?
A: A bit of a trick question. For the first 40 miles it will get infinite mpg, because no gas will be burned. When the generator starts, the car will get an equivalent of 50 mpg thereafter. One can calculate the average mpg per for any length drive starting with a full battery: Total MPG = 50xM/(M-40)
Q: When will the car be available?
A: The plan is to have the car available for mass purchase in late 2010, as a 2011 model year.
Q: What type of batteries will the Chevy Volt use?
A: The car is being designed around an advanced battery pack which uses lithium-ion chemistry. This chemistry appears in cell phones and laptops. For automotive use the packs and cells will be more powerful and safe.
Q: Is it a four or five-seater?
A: Four
Q: How much will the car cost?
A: Goal is to be less than $30,000, but first versions might be closer to $40,000.
Q: What is the cost of operation of the car
A: With current average U.S. electric rates of ~10 cents/kwh it should cost 80 cents to drive for the first 40 miles, and then get 50 mpg thereafter using gasoline (market rate).
Q: Why is the car taking so long to make?
A: GM reports that the battery packs are not ready yet. They have to be thoroughly tested to ensure safety and reliability.
Q: Who is making the Volt’s battery packs?
A: Right now GM is evaluating products from a company called A123, working with Continental, and a company called CPI working with LG Chem. The best product will presumably be used.
Q; Does the car use regenerative braking?
A: Yes. This means when the car is slowed, the kinetic or motion-based energy will be recaptured as electricity stored in the battery
