Sales of the 2011 Volt began in the U.S. in mid-December 2010 followed by various European countries and other international markets in 2011. Global combined Volt/Ampera family sales passed the 100,000 unit milestone in October 2015, with the U.S. as the leading market with over 84,600 Volts delivered. , over 9,900 Opel/Vauxhall Ampera cars had been sold in Europe. The Netherlands is the world's second largest market, and leads the European region with almost 5,000 Amperas and over 1,000 Volts registered. Canada ranks next with over 5,000 Volts sold through October 2015. The Volt/Ampera family of vehicles is the world's all-time best-selling plug-in hybrid vehicle . 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. When the engine is running it may be periodically mechanically linked (by a clutch) to a planetary gear set, and hence the output drive axle, to improve energy efficiency. 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 , with a combined electric mode/gasoline-only rating of equivalent (MPG-equivalent). The second generation Volt improved battery system and drivetrain increased the all-electric range to , its EPA rated fuel economy in charge-sustaining mode to , and the combined city/highway fuel economy in all-electric mode to 106 miles per gallon gasoline equivalent (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 has 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, 2012 European Car of the Year, and 2016 Green Car of the Year. Controversies regarding the Volt include the extent to which the U.S. federal government may have participated in the Volt’s development, which continued through General Motors' 2009 government-led bankruptcy,〔 and concerns about the battery pack fire risk following a crash test that the National Highway Traffic Safety Administration (NHTSA) performed on a Volt in 2011.〔〔〔 At the completion of its investigation NHTSA concluded that no discernible defect trend exists.〔〔 == Terminology == The Society of Automotive Engineers' (SAE) definition of a hybrid vehicle states that the vehicle shall have "''two or more energy storage systems both of which must provide propulsion power, either together or independently.''" General Motors has avoided the use of the term "hybrid" when describing its Voltec designs, even after the carmaker revealed that in some cases the combustion engine provided some assist at high speeds or to improve performance. Instead General Motors describes the Volt as an electric vehicle equipped with a "range extending" gasoline powered internal combustion engine (ICE) as a genset and therefore dubbed the Volt an "Extended Range Electric Vehicle" or E-REV. In a January 2011 interview, the Chevy Volt's Global Chief Engineer, Pamela Fletcher, referred to the Volt as "an electric car with extended range." According to the Society of Automotive Engineers (SAE) definitions, the Volt is a plug-in hybrid vehicle, due to the combination of an internal combustion engine and two electric motors, along with a battery that can accept off-board energy.〔 The Volt operates as a purely electric vehicle for the first in charge-depleting mode. When the battery capacity drops below a pre-established threshold from full charge, the vehicle enters charge-sustaining mode, and the Volt's control system will select the most optimally efficient drive mode to improve performance and boost high-speed efficiency.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Chevrolet Volt」の詳細全文を読む スポンサード リンク
