Chevrolet Bolt EV
The all-electric Chevrolet Bolt EV is so cutting edge that it makes all other affordable electric vehicles seem irrelevant. Its impressive 238-mile EPA-certified driving range makes it usable as a daily driver, and its powerful and responsive electric motor provides plenty of fun along the way. At the same time, the Bolt EV is also a practical hatchback with a roomy rear seat and lots of cargo space. It may not look as cool as a Tesla, but the 10Best-winning Bolt EV is arguably a bigger step forward for autodom—for a fraction of the price.
a What's New For Chevrolet 2017 Version?
The Bolt EV is a completely new model for 2017. Don’t confuse it with the similarly named Chevrolet Volt, a plug-in hybrid with both an electric motor and a gasoline engine—and far less electric range.
Trims and Options We’d Choose .
The Bolt EV’s affordability is paramount in its appeal, so we’d keep it simple by sticking with the base LT model rather than the ritzier Premier. The LT comes standard with features such as:
• 10.2-inch touchscreen with Apple CarPlay and Android Auto
• Proximity-key entry and push-button start
• Backup camera
• 4G LTE with mobile Wi-Fi
The Bolt EV LT offers two affordable option packages that we’d choose: the $555 Comfort and Convenience package (includes heated front seats and steering wheel) and the $495 Driver Confidence package (blind-spot warning, rear cross-traffic alert, rear parking sensors). We’d also add DC fast-charging capability for $750. All in, our well-equipped Bolt stickers for $39,295—a number that can be offset by a federal tax credit of $7500 available to electric-vehicle buyers. Some states offer additional rebates, tax credits, high-occupant-lane privileges, or other incentives to EV buyers as well. Here’s our explanation of how the EV tax credit works. 60 kWh Battery System Having more than 1.3 billion miles of EV experience from the Chevrolet Volt helped Bolt EV battery engineers and strategic partner LG Electronics to develop an all-new cell and battery pack to offer more than an estimated 200 miles of range. Battery system preliminary specifications include: 60 kWh lithium-ion battery pack. 288 lithium ion cells Five sections 10 modules 96 cell groups – three cells per group 960 lbs. (435 kg) total weight “You usually have a battery cell that delivers either the desired levels of energy or power, but not traditionally both. With this cell design and chemistry we were able to deliver a battery system with 160 kilowatts of peak power and 60 kilowatts hours of energy,” said Gregory Smith, Bolt EV battery pack engineering group manager. The battery uses active thermal conditioning, similar to the Chevrolet Volt, to keep the battery operating at its optimum temperature, which results in solid battery life performance. The Bolt EV battery will be covered by an 8-year/ 100,000 mile (whichever comes first) limited warranty. Inside the battery pack – which spans the entire floor, from the front foot well to back of the rear seat – is a new cell design and chemistry. The nickel-rich lithium-ion chemistry provides improved thermal operating performance over other chemistries, which requires a smaller active cooling system for more efficient packaging. The chemistry allows the Bolt EV to maintain peak performance in varying climates and driver demands. The cells are arranged in a “landscape” format and each measures in at only 3.9 ins. (100 mms) high and 13.1 ins. (338 mms) wide providing improved packaging underfloor. The lower profile cell design enabled the vehicle structure team to maximize interior space. The battery system is mated to a standard equipment 7.2 kW onboard charger for regular overnight charging from a 240-V wall box. A typical commute of 50 miles can be recharged in less than two hours. Bolt EV also features an optional DC Fast Charging system using the industry standard SAE Combo connector. Using DC Fast Charging, the Bolt EV battery can be charged up to 90 miles of range in 30 minutes. Outside temperatures may affect charging times. Regen System Provides One-Pedal Driving Regenerative braking has become more than just a tool to boost range, it’s also transformed into a feature that can provide an improved EV driving experience. The Bolt EV features a new regenerative braking system that has the ability to provide one pedal driving. “Interviews with EV enthusiasts indicated their desire for one pedal driving capability on the Bolt EV. One pedal operation boosts the thrill and uniqueness of EV driving,” Tavel said. Through a combination of increased regenerative deceleration and software controls, one pedal driving enables the vehicle to slow down and come to a complete stop without using the brake pedal in certain driving conditions. When operating the Bolt EV in “Low” mode, or by holding the Regen on Demand paddle located on the back of the steering wheel, the driver can bring the vehicle to a complete stop under most circumstances by simply lifting their foot off the accelerator, although the system does not relieve the need to use the brake pedal altogether. Operating the Bolt EV in “Drive” mode and not pulling the paddle while decelerating delivers a driving experience where usage of the brake pedal is required to stop.60 kWh Battery System
