DETROIT -- China, once lagging in electrified-vehicle deployment, has become a global leader, according to a new measurement created by consulting firm AlixPartners.
In the company's Automotive-Electrification Index, unveiled Wednesday, "e-range" is calculated by multiplying the number of electric vehicles sold by the electric range of those vehicles.
The Greater China region sold 14 million miles (22.5 million km) worth of electric range in the second quarter of this year.
- Europe: 7.83 million miles
- North America: 6.15 million miles
- Japan/Korea: 1.29 million miles
In the first quarter of 2013, China was last globally, with 223,700 miles sold.
They're not "first by a little bit, they're first by a lot," said Mark Wakefield, a consultant with AlixPartners, at the Technology in Motion conference here. "They're selling long-range vehicles, and they're selling a lot of them."
The new index uses publicly available data on vehicle ranges, volume sold and market share to calculate e-range. Plug-in electric vehicles are measured solely by range of battery capacity, biasing the metric toward longer-range full EVs. Hybrids are not included.
"We're normalizing it to the [internal combustion engine] experience," Wakefield said. "A 300-plus mile range basically meets everybody's needs."
In comparing companies, five Chinese automakers were in AlixPartners' top 10 list of miles sold in the second quarter: BYD Auto, BAIC Motor., Zhejiang Geely Holding Group, Ninghai Zhidou Electric Vehicles and Anhui Jianghuai Automobile.
Tesla was No. 1 overall, at 6.61 million miles sold. Others in the top 10:
- No. 2: Renault-Nissan Alliance -- 3.72 million miles
- No. 5: General Motors -- 1.64 million miles
- No. 7. BMW Group -- 1.26 million miles
- No. 10. Hyundai Motor -- 1.14 million miles.
