The Chevrolet Volt hasn't yet gone on sale, but General Motors is looking at ways of expanding its electric vehicle lineup. Chevy, along with partner LG, is employing a group of all-electric cars in the form of the Cruze. The sedans are part of a demonstration fleet which is located in Seoul, South Korea and is being used to provide data in an electric vehicle research project. The goal is to gather information on driving patterns and charging behavior in addition to consumer acceptance.

The Cruze EVs, along with some Daewoo Lacetti Premieres EVs, are the first fleet of full-size electric vehicles and should provide invaluable information for The General. Staying full-size means not sacrificing cargo space, so the battery pack is mounted to the underbody, leaving the trunk area open for plenty recyclable, canvas grocery bags.

The current range of the Cruze EV is around 100 miles and the car is capable of a 0-60 run in 8.2 seconds. The Cruze EV can hit a top speed of 102.5 miles per hour. Currently, the Cruze EV can be recharged via a standard 220-volt outlet in 8 to 10 hours, however the researchers are testing "quick charge" methods to reduce that figure.

The program, which begins at the end of October, is currently a demonstration and research project for South Korea only. There have been no announcements made discussing the Cruze EV coming stateside.

GM Extends EV Development with Demo Fleet of Electric Chevrolet Cruzes
2010-09-18

Developed by GM and LG for Demonstration Fleet in South Korea
Early Testing Estimates Up to 160 km (100 Miles) of Range on a Single Charge
Project to Begin by End of October

Seoul – General Motors today announced a demonstration project to explore market needs and customer acceptance of battery electric vehicles in Korea. The project involves a fleet of electric vehicles based on the successful Chevrolet Cruze. The result of shared development with GM Daewoo, LG Chem and LG Electronics, the electric Cruzes will be part of a demo fleet that will operate in South Korea's capital, Seoul.

The project is aimed at benefiting GM's core vehicle electrification competencies, which include batteries, electric motors, power controls and charging. It will provide real-world data on customer acceptance of battery electric vehicles, studying driving patterns and charging behavior while sharing costs and resources. This is a key initiative in GM's global battery and electric vehicle development strategy. The demo project is expected to launch by the end of October. GM demonstration fleets with other partners are also being launched in other urban markets later this year.

The Cruze EV demo fleet will be the first full-size sedan electric vehicles to hit the road and will be powered by batteries from LG Chem and propulsion systems (motor/inverter) from LG Electronics. GM's EV demo fleet in South Korea will consist of Chevrolet Cruzes and GM Daewoo Lacetti Premieres. GM currently markets the vehicle under the local brand in South Korea.

"This Cruze EV demonstration project reinforces GM's commitment to being a leader in the development of electric vehicles and green technologies, building on our portfolio of hybrids and the Chevrolet Volt," said Karl Stracke, Vice President, GM Global Vehicle Engineering. "We'll apply the learnings from this and our other demo projects to help us deliver the world's best vehicles for our customers."

The Cruze EV is equipped with a 31-kWh battery that generates maximum power of 150 kW. The demonstration fleet will be monitored closely to determine the amount of real-world range achievable by a vehicle of its size. On specific test schedules conducted by LG Chem, the demonstration vehicles may achieve a range of up to 160 km (100 miles). The vehicles can go from 0 to 100 km/h (60 miles per hour) in 8.2 seconds with a maximum speed of 165 km/h (102.5 miles per hour).

On a standard household 220-volt outlet, the Cruze EV can be fully recharged in 8 to 10 hours. Part of the demonstration fleet's task is to test a "quick charge" application that could reduce the charge time significantly.

"Although there is much more work to be done, our ability to develop this vehicle in less than a year offers a peek at the very promising plans we have for our customers in Korea and around the world," said Mike Arcamone, GM Daewoo President and CEO.

While battery packs often occupy trunk space, the Cruze EV's battery pack is mounted on the underbody. This gives the Cruze EV the same trunk space as conventional vehicles with gasoline engines.

"Expanding the domestic electric vehicle market carries significant meaning for collaboration between GM Daewoo and LG Chem," said Peter Bahnsuk Kim, Vice Chairman and CEO of LG Chem. "Over the past two years, we have forged a strong partnership with GM, and now we look forward to doing the same with GM Daewoo in our home country."

Since 2008, GM has been working with LG Chemical, which is the exclusive supplier of battery cells for the Chevrolet Volt electric vehicle with extended range. The Volt enters the U.S. market later this year. The development of the Chevrolet Cruze EV demo fleet will expand this collaboration.
