“This could be the first BEV that makes sense.” Wayne Gerdes – CleanMPG – Jan. 11, 2016 2017 Chevrolet Bolt from the floor of the 2016 #NAIAS. $35k to start and 200+ mile range is only the beginning. The 2017 Chevrolet Bolt EV is the epitome of an affordable and longer range BEV. With a $35k price tag to start not including incentives, it may still be a bit out of the mainstream but comes closest to fulfilling an electrified future for the masses. Here are some of the drivetrains details from GM itself. Like most BEVs on the road, the Bolt EV’s drive system uses a single high capacity electric motor that is both powerful. The engineering team designed the Bolt EV’s electric motor with an offset gear and shaft configuration tailored to meet efficiency and performance targets. The motor is capable of producing up to 266 lb.-ft. of torque and 200 hp of power. Combined with a 7.05:1 final drive ratio, it helps propel the Bolt EV from 0 to 60 mph in less than seven seconds. 2017 Chevrolet Bolt Driven on-stage by GM’s Chairman and CEO, Mary Barra and Mark Reuss, Exec. VP, Global Product Development, Purchasing and Supply Chain. Power delivery is controlled by Chevrolet’s first Electronic “Precision Shift” system. This shift and park-by-wire system sends electronic signals to the Bolt’s drive unit to manage feel and delivery of power and torque, based on drive mode selection and accelerator inputs. A by-wire shifter requires less packaging space than a traditional mechanical shifter, resulting in more interior space and improved interior layout. From the show floor: 2017 Chevrolet Cruze hatch 60 kWh Battery System LG Electronics developed an all-new cell and battery pack to offer more than 200 miles of range. Preliminary specifications: 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 All told, 160 kW of peak power and 60 kWh of energy. The battery uses active thermal conditioning to keep the battery operating at its optimum temperature. The Bolt BEV battery will be covered by an 8-year/ 100,000 mile (whichever comes first) limited warranty. Inside the 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 Li-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 each measures in at only 3.9 ins. high and 13.1 ins. 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 Level2 charger. A typical commute of 50 miles can be recharged in less than two hours from the same Level2. The Bolt EV also features an optional Level3 Fast DC Charging system using the industry standard SAE Combo connector that can charge up to 90 miles of range in just 30 minutes. Outside temperatures may affect charging times. Regen System Provides One-Pedal Driving Regenerative braking increases range a bit and the Bolt EV includes a new regenerative braking system that has the ability to provide one pedal driving. I am not a fan as it is too aggressive as experienced in some of BMWs first systems but some like it. Fortunately owners will have a choice. 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. 2017 Chevrolet Bolt Specifications Body style/driveline: FWD, 5-passenger, 5-door all-electric CUV Construction: Steel and Aluminum Key competitors: Nissan Leaf, BMW i3, Ford Focus Electric, Kia Soul EV, VW eGolf Mercedes-Benz B-Class Manufactured: Orion Township, Mich.

With costs coming down, it may be the car that brings us closer to an all-electric fleet. The LEAF moved the needle. The Bolt will move the needle even further albeit $35k for a B/C segment is still hard to sell. By 2020, a PHEV drivetrain based off the Bolt’s capabilities could move GMs entire fleet efficiency as evidenced by the upcoming 48/45 2017 Malibu Hybrid. Just imagine a Sonic, Cruze, Impala and even their CUVs using a similar drivetrain.
