Limited Range

It’s everybody’s cool EV term: Range Anxiety! It stands for the worry that occurs because most affordable electric cars only have about 80 to 100 miles of range, and take hours to fully refuel. EV advocates will argue that 100 miles of range is plenty for most driving. As a result, nearly all electric car drivers rarely if ever experience range anxiety. It’s also true that the range and cost of electric car batteries are incrementally improving every year, with 200-plus mile EVs starting to arrive in late 2016. Still, unless you drive an electric car with a backup range-extending engine, you need to properly plan: to assure that routes beyond predictable local driving are within range (or allow for a time to recharge).

Long Refueling Time

Concerns about range are closely tied with issues related to how long it takes to refuel an electric car. EVs commonly can add about 20 to 25 miles of range in an hour of charging from a 240-volt source of electricity. So, while you can’t run down to the gas station and add a couple hundred miles of range in five to 10 minutes, and while many road trips are not advisable, drivers putting typical amounts of miles on their cars will not be impinged by recharging times measured in hours—as long as they remember to plug in before going to sleep. (One other factor: public DC Quick Chargers, capable of adding about 50 miles of range in around 20 to 25 minutes, are increasingly available in regions with relatively high numbers of electric cars.)

Higher Cost

The current crop of electric cars are mostly priced between $30,000 and $40,000. That makes EVs considerably more expensive than comparably equipped small to midsized gas-powered vehicles. In this light, EVs are indeed expensive. However, cost comparisons usually fail to consider a number of factors, including incentives often valued at $10,000; competitive lease rates as low as $199 a month; lower maintenance costs; and a luxury feel and amenities that far exceed what’s found in those cheaper gas models.

Lack of Consumer Choice

The 40 of or so plug-in electric vehicles on the market consist mostly of compact pure electric cars and midsize plug-in hybrid sedans. The field is quickly expanding, with plug-in hybrid SUVs, a plug-in minivan and the Tesla Model X, an all-electric SUV. Several major automakers set aggressive goals of releasing a dozen or more new plug-in models in the coming years, promising electric models in many different segments. Unfortunately, the style of some popular EVs is polarizing: you either love it or, if you hate it, you hold off on purchasing an electric car. Yet, the trend is to offer electric versions of existing attractive models, rather than electric-only models that can look overly futuristic to average buyers.
