Sales of the 2011 Volt began in the United States in mid-December 2010, followed by some European countries and other international markets in 2011. Global combined Volt/Ampera-family sales totaled about 177,000 units by the end of October 2018. The U.S. was the leading market, with 157,054 Volts delivered through the end of 2019, followed by Canada with 16,653 Volts sold through September 2018. Just over 10,000 Opel/Vauxhall Ampera cars had been sold in Europe as of June 2016. Until December 2018, the Volt/Ampera family of vehicles was the world's bestselling plug-in hybrid vehicle. When it was discontinued, the Chevrolet Volt was still listed as the top-selling plug-in hybrid in the American market.

The Volt operates as a pure battery electric vehicle until its battery capacity drops to a predetermined threshold from full charge. From there, its internal combustion engine powers an electric generator to extend the vehicle's range as needed. While running on gasoline at high speeds the engine may be mechanically linked (by a clutch) to a generator set, improving efficiency by 10% to 15%. The Volt's regenerative braking also contributes to the on-board electricity generation. Under the United States Environmental Protection Agency (EPA) cycle, the 2013‍–‍15 model year Volt all-electric range is 38 mi (61 km), with a combined electric mode/gasoline-only rating of 62 mpg‑US (3.8 L/100 km; 74 mpg‑imp) equivalent (MPG equivalent).

The second-generation Volt's improved battery system and drivetrain increased the all-electric range to 53 miles (85 km), its EPA-rated fuel economy in charge-sustaining mode to 42 mpg‑US (5.6 L/100 km; 50 mpg‑imp), and the combined city/highway fuel economy in all-electric mode to 106 MPG-e, up from 98 MPG-e. Deliveries to retail customers in the U.S. and Canada began in October 2015 as a 2016 model year.

The Volt won several awards, including the 2009 Green Car Vision Award, 2011 Green Car of the Year, 2011 North American Car of the Year, 2011 World Green Car, 2011 SAE Best engineered car, 2012 European Car of the Year, and 2016 Green Car of the Year.

First generation (2010–2015)

2011 Chevrolet Volt

The production design model officially unveiled on September 16, 2008, as part of General Motors (GM) centennial celebration at the Wintergarden headquarters in Detroit.[1] The production model differed greatly in design from the original concept car. The carmaker cited necessary aerodynamic changes needed to reduce the concept car's high drag coefficient of Cd=0.43[2] down to Cd=0.28,[3] still higher than the Toyota Prius Cd=0.25. Another reason was the use of General Motors's new global compact vehicle platform Delta II to keep costs reasonable, and shared with the 2010 model year Chevrolet Cruze.[4] Another significant difference from the concept car was the seating, as the production Volt seats four rather than five passengers. This change was due to the higher-than-usual central tunnel that runs from the front console to the rear seat that houses the car's T-shaped battery pack.[5]

After the concept was put into the pipeline for production, GM began looking for a partner to develop the Volt's lithium-ion battery pack. The carmaker evaluated about 25 battery cell chemistries and constructions from around two dozen lithium-ion battery makers around the world.[6] Due to their more promising cell technologies, two companies were selected in June 2007, Compact Power (CPI), which uses a lithium manganese oxide (LiMn2O4) cell made by its parent company, LG Chemical; and Continental Automotive Systems, which uses lithium iron phosphate based cylindrical cells made by A123Systems.[6][7][8] By the end of October 2007 CPI (LG Chem) delivered their finished battery pack prototypes, and A123 delivered theirs by January 2008. GM's testing process was conducted at the laboratory the carmaker had created for the GM EV1 program. The battery packs included monitoring systems designed to keep the batteries cool and operating at optimum capacity despite a wide range of ambient temperatures.[6][8] To ensure the battery pack would last 10 years and 150,000 miles (240,000 km) expected for the battery warranty, the Volt team decided to use only half of the 16 kWh capacity to reduce the rate of capacity degradation, limiting the state of charge (SOC) up to 80% of capacity and never depleting the battery below 30%.[8][9] GM also expected the battery to withstand 5,000 full discharges without losing more than 10% of its charge capacity.[8] According to GM, as of August 2016, no batteries had been changed due to degradation.[10]

In April 2008 GM started extensive battery testing. In two years, the carmaker put the battery packs to the equivalent of 150,000 real-world miles (240,000 km) and 10 years of use.[8] The durability of the battery pack was tested for a broad range of extreme ambient conditions including a shaker table to simulate potholes and a thermal chamber, to simulate temperatures varying from 116 °F (47 °C), typical of the Southwest deserts, to −40 °F (−40 °C) typical of the Alaskan tundra.[6] In April 2008 the lithium-ion battery pack was placed in Chevrolet Malibus fitted with the Volt powertrain to be used as test mules for further real-world testing.[8][11] In October 2008, GM chose CPI (LG Chemical) to provide the battery systems for the first production version of the Volt.[12][13] In July 2008, GM confirmed that a non-turbocharged, 1.4 L 4-cylinder engine would be used as the range extender, and that the intention was to build it in Flint, Michigan.[14] In April 2009, General Motors let journalists test the Volt powertrain without the range-extending generator in the body of Chevrolet Cruze sedans that GM used as test mules at the GM Technical Center in Warren, Michigan.[15]

The first pre-production test car based on the final Volt design was built in June 2009, in Warren, Michigan,[16][17] and by October 2009, 80 Volts had been built and were tested under various conditions.[17][18] On March 31, 2010, the first factory-built Volt was produced at the Detroit Hamtramck Assembly Plant to test the production line and for quality control purposes, both of the tooling and the pre-production vehicles produced before regular production began.[19][20]

Tony Posawatz was the Volt Vehicle Line Director from 2006 to 2012,[21] and he was known as employee #1 and led the team from concept to production.[22]

 
Final production vehicle, the 2011 Chevrolet Volt

General Motors held a ceremony at its Detroit Hamtramck Assembly Plant on November 30, 2010, to introduce the first Chevrolet Volt off the assembly line. The first Volt built for retail sale was earmarked for display at GM's Heritage Center museum in Sterling Heights, Michigan.[23] The second unit was offered at a public auction, with an opening bid of US$50,000 and it was won by Rick Hendrick who paid US$225,000. The proceeds went to fund mathematics and sciences education in Detroit through the Detroit Public Schools Foundation.[24] Deliveries to retail customers in the United States began in mid December 2010.[25] Volt deliveries began in Canada in September 2011.[26][27] The first deliveries of the Chevrolet Volt in Europe took place in November 2011.[28][29] The European version of the Volt, the Opel Ampera, was released to retail customers in Europe in February 2012.[30] Deliveries of the right-hand drive Vauxhall Ampera in the UK began in May 2012.[28] The Holden Volt was released in Australia in December 2012.[31]

Second generation (2016–2019)

edit

2018 Chevrolet Volt

The second generation Chevrolet Volt was unveiled at the January 2015 North American International Auto Show.[32] Retail deliveries began in the United States and Canada in October 2015 as a 2016 model year, with 1,324 units delivered in the U.S. that month.[33][34] Availability in the American market was limited to California and the other 10 states that follow California's zero emission vehicle regulations. GM scheduled the second generation as a 2017 model year to be released in the 39 remaining states by early 2016.[33] Manufacturing of the 2017 MY Volt began in February 2016, and the first units arrived at dealerships at the end of February 2016. The 2017 model complied with stricter Tier 3 emissions requirements and was available nationwide.[35]

The second generation Volt had an upgraded powertrain with a 1.5-liter engine that uses regular gasoline; the 18.4 kWh battery pack had new chemistry that stored 20% more electrical energy using fewer cells, 192 compared with 288 on the 2014 Volt. It had a new power controller that was integrated with the motor housing; the electric motors weighed 100 lb (45 kg) less and used smaller amounts of rare earth metals. GM engineers explained that the second generation Volt was developed with extensive input from Volt owners.[32][36][37]

The improvements allowed the 2016 Volt to deliver better EPA ratings than the first generation model. The all-electric range was rated at 53 mi (85 km), up from 38 mi (61 km) attained by the 2015 Volt. The gains in efficiency allowed the second generation to improve its combined fuel economy in gasoline-only (charge-sustaining) mode to 42 mpg‑US (5.6 L/100 km; 50 mpg‑imp), up from 37 mpg‑US (6.4 L/100 km; 44 mpg‑imp) for the previous model. The second generation rating for combined city/highway fuel economy in all-electric mode was 106 miles per gallon gasoline equivalent (MPGe; 2.2 Le/100 km), up from 98 MPGe (2.4 Le/100 km) for the 2015 first generation model.[38][39] The combined gasoline-electricity fuel economy rating of the 2016 model year Volt was 77 mpg‑US (3.1 L/100 km; 92 mpg‑imp) equivalent, 82 MPGe (2.9 Le/100 km) in city driving and 72 MPGe (3.3 Le/100 km) in highway.[40] Both the all-electric range and fuel economy ratings are the same for the 2017 model year Volt.[41]

The second-generation Volt seats five rather than four, as in the first generation.

In April 2013, CEO Daniel Akerson announced that GM expected the second generation Volt to be priced on the order of US$7,000 to US$10,000 lower than the 2013 model year with the same features.[42] The 2016 Volt pricing started at US$33,170 before any government incentives, plus US$825 for destination. The starting price was US$1,175 lower than the 2015 Volt.[43] In California, order books for the second generation Volt were opened on May 28, 2015.[44]

In July 2014, Opel announced that due to a slowdown in sales, they would discontinue the Ampera after the launch of the second generation Volt—and that between 2014 and 2018, Opel planned to introduce a successor electric vehicle in Europe.[45] General Motors announced in February 2016 that the all-electric Opel Ampera-e hatchback would go into production in 2017. This is the European version of the Chevrolet Bolt EV.[46][47]

In April 2015, General Motors confirmed that it would not build the second-generation Volt in right-hand-drive configuration. Only 246 units had been sold in Australia by mid-April 2015, and the Holden Volt was discontinued once the remaining stock was sold .[48]
