In its last model year before a revised version is introduced, the 2015 Chevrolet Volt is the only high-volume plug-in electric car from General Motors. The compact five-door hatchback provides 35 to 40 miles of battery power--which covers a majority of trips in the U.S.--and then switches on a four-cylinder range-extending engine to generate electricity that runs the Volt on longer trips without recharging.
GM says that Volt owners cover about two-thirds of all of their miles and fully 80 percent of their commute travel on grid electricity used to charge the battery. Still, at $35,000, the Volt remains expensive for a compact car with only four seats. It does, however, have the highest owner satisfaction ratings of any car in the history of General Motors--which indicates promise for the future as battery costs fall and GM launches a second-generation model.
While more Volts have been sold in the U.S. than any other plug-in car--though the Nissan Leaf is catching up fast--that amounts only to about 23,000 cars in each of the last two years. By way of comparison, Chevy sells almost that many Cruze compact sedans each month. Moreover, sales are heavily regional--largely in states and areas with electric-car incentives, including California--and the Volt remains a rarity in other regions.
Both those facts contribute to continuing confusion over the Volt and how it works--including a myth, which still crops up, that it can only go 40 miles at a time. Whether it's bad reporting, bad maketing, or the brand-new combination of two powertrains, many potential buyers simply don't "get" the Volt--or why its owners would be so astoundingly passionate about it--and often dealers make no effort to help them along.
Along with the battery-electric Nissan Leaf, the Chevy Volt pioneered the market for modern plug-in volume cars back in December 2010. It hasn't changed much since then, and this may be its final model year before a revised Volt appears next January at the Detroit Auto Show, going into production next summer as a 2016 model.
The shape of the 2015 Chevrolet Volt remains the same: It's a squat, slab-sided five-door hatchback with a high tail and relatively small side windows. The tailgate is almost horizontal and, like that of the Toyota Prius hybrid whose proportions it somewhat echoes, has a pair of windows: one long but almost horizontal, the other small but vertical to increase rearward visibility. Inside, the four seats are well-bolstered but low to the floor, meaning occupants sit deep inside the car and peer out through the narrow windows. The Volt's center console is finished in high-gloss plastic and offers an array of touch-sensitive switches that felt advanced in 2011 but could use some rethinking by now.
It's what's under the hood that makes the Volt special, of course. The 2015 Volt remains one of a pair of GM vehicles using the Voltec range-extended electric powertrain (the other is the very low-volume Cadillac ELR coupe). Using a gasoline engine as a backup for longer distances makes the Volt different a battery-electric car that can only be "refueled" by plugging it in to recharge--closer to that of a hybrid. And while its 38 miles of rated electric range may seem very low, it's enough for almost 80 percent of the journeys made by U.S. vehicles. For the rest, the engine gives unlimited range at the cost of a 10-minute fill-up. But Volt owners report that they cover 65 to 80 percent of their total miles on grid electricity--and, on average, visit the gas station every 900 miles, or just once a month.
The Volt's lithium-ion battery pack, shaped like a giant T, is mounted in the large tunnel between the front seats and extends underneath the rear seats. For 2015, it holds incrementally more energy--17.1 kilowatt-hours--than last year's 16.5 kWh. While its EPA-rated range of 38 miles remains the same, owners may find it can go slightly further on battery power in real-world use than the 2014 model. Once that range depletes the battery, the 1.4-liter four-cylinder engine switches on to power a generator that produces more electricity to keep the Volt going for another 250-plus miles.
But unlike plug-in hybrids, the range-extended electric Volt's battery must be depleted before the engine turns on--its electric motor is powerful enough to run the car under any circumstances until then. That contrasts to plug-in hybrids--including the Ford C-Max and Fusion Energi models and the plug-in Toyota Prius--which turn on their engines under maximum acceleration regardless of battery state.
This setup is also known as a "series hybrid," though in the Volt's case there's an asterisk: Once the engine has switched on, under some high-speed conditions, it can be clutched directly into the transmission to provide torque to assist the electric motor. At high speeds, the car calculates the most energy-efficient way to propel itself--and that may be using the engine to assist the electric motor driving the front wheels. Either way, the Volt's rated fuel economy running on gasoline is 37 mpg combined. While not quite as good as the Prius hybrid's 50 mpg, that's better than the Chevy Cruze that sits next to the Volt on showroom floors.
Meanwhile, a Volt can be plugged in for 8 to 10 hours to recharge its battery on standard 120-Volt household current. If you use a 240-Volt Level 2 charging station, it takes about half that time.
On the road, a Volt accelerates briskly (and quietly), rides and drives well, copes with corners adeptly due to the low position of the heavy battery pack. The electric power delivery is seamless, with no steps as the transmission shifts, and like any electric car, the Volt is quiet on the road, with tire and wind noise more apparent when engine noise is absent.
The 2015 Chevy Volt remains at a base price of $35,000, including the mandatory delivery fee. Accessories can take the bottom-line total over the $40,000 mark. It's eligible for a $7,500 Federal tax credit and a variety of state, local, and corporate incentives as well--including state purchase rebates of $2,500 in California or $5,000 in Georgia. Those Volts sold in California and New York carry a special emissions package that qualifies them for permits that allow their drivers to use carpool lanes with only a single occupant--a very valuable privilege during California's epic rush-hour traffic.
Volt shoppers may consider the Toyota Prius and its plug-in model. Chevy has said in the past that the Prius was the most commonly traded-in car for a new Volt. There is also the all-electric Nissan Leaf, whose sales are surging after two years of U.S. production, as well as Ford's pair of C-Max and Fusion Energi plug-in hybrids. The Chevy Volt has the highest customer satisfaction rate of any car GM has ever built. More important yet for GM is that a majority of Volt buyers are new to the Chevrolet brand--a huge win for its highest-volume brand.
Every buyer will need to calculate payback for the specific circumstances, including lower cost of electricity. That averages 12 cents per kWh nationwide, but can be as low as 3 cents or as high as 25 cents depending on location. Running the Volt on grid power generally costs one-fifth to one-third as much per mile as running a conventional car on gasoline.
