At the opening of Auto Guangzhou 2012, Shanghai General Motorslaunched its first localized new energy vehicle, the Sail SPRINGO EV. The vehicle was developed by Shanghai GM and the Pan Asia Technical Automotive Center (PATAC), making it the first production electric vehicle created by a Chinese joint venture.
A limited number of the Sail SPRINGO EVs will initially be sold starting in Shanghai as part of a trial program to enable Shanghai GM to better understand Chinese consumers’ preferences and user habits for electric vehicles. The SPRINGO EV will be sold for RMB 258,000 (US$41,460). Buyers in Shanghai will enjoy incentives of up to RMB 60,000 (US$9,642) from the central government and RMB 40,000 (US$6,428) from the Shanghai government. In addition, the car will qualify for a free local Shanghai license plate exclusively for electric vehicles.
Based off a new electric vehicle architecture developed by Shanghai GM in conjunction with PATAC, the Sail SPRINGO EV features a permanent magnet electric motor capable of producing 85 kW of power and up to 510 N·m (376 lb-ft) of torque, allowing acceleration from 0 to 100 km/h in just over 10 seconds. (As a comparison, the new Chevrolet Spark EV uses a 100 kW motor with 542 N·m of torque. Earlier post.)
Pushing the Sport button provides a 20% boost in acceleration at the beginning and middle of the torque curve compared to pressing the accelerator in a gasoline-powered vehicle. The top speed is 130 km/h (81 mph). Its stability during high-speed cruising and cornering is optimized by a new tailored full-frame chassis with an enhanced stabilizer bar and tuned suspension.
Electric range is 130 km (81 miles) under a variety of road conditions and 200 km (124 iles) at a constant speed of 60 km/h (37 mph). The Sail SPRINGO EV consumes less than 15 kWh for every 100 km—less than most electric vehicles currently on the market. The Sail SPRINGO EV costs RMB 4.6 (US$0.74) per 100 km to drive when charged during lower-cost off-peak hours (between 10:00 p.m. and 6:00 a.m.).
The powertrain system features an advanced battery liquid cooling system, an innovative motor efficiency optimizer, a rechargeable energy storage system mated to a low gear design, and low-rolling resistance tires. More balanced power output with regenerative braking helps keep energy consumption at the lowest level.
The Sail SPRINGO EV can be charged using a 3.3-kW charging station or a standard household outlet. It takes approximately seven hours for the battery to be fully charged using a dedicated 220V connection. There are three charging modes available: immediate charging, time delay charging, and time delay and rate charging.
Vehicle charging can also be managed and monitored remotely using a smart phone mobile app provided by Shanghai OnStar. Owners can use the app to perform a range of functions remotely, such as starting the vehicle’s heater or air conditioner. OnStar’s service system also carries out remote vehicle monitoring and analysis of other vehicle systems, and provides drivers with additional vehicle information such as tire pressure. If abnormal data is detected, the OnStar system will immediately contact the owner to provide safety information and instructions.
Another feature allows owners to check energy usage and remaining charge level with the Energy Leaf button.
Developed to meet global electric vehicle safety standards, the Sail SPRINGO EV fully complies with safety requirements for pure electric vehicles in China. Its newly designed front and rear anti-collision beams made from ultra-high strength steel and its body structure protect the battery pack in the event of a collision.
All of Shanghai GM’s new energy vehicles, including the Sail SPRINGO EV, will be sold through an exclusive “Drive to Green” sales network. The first showroom is expected to open in the first half of 2013 in Shanghai. The exclusive sales and aftersales service network will be expanded to key new energy vehicle demo cities based on local market conditions and the development of the new energy vehicle industry and charging infrastructure.
The Sail SPRINGO EV will come with a vehicle warranty of three years or 80,000 km, as well as a battery warranty of five years or 100,000 km.
Green drive strategy. Also at the auto show, Shanghai GM Shanghai described its future “Green Drive Technology Strategy”. Ye Yongming, general manager of Shanghai General Motors, said that the new strategy serves as the planning blueprint for new energy products for 2020—notably battery-electric and extended range electric vehicle technologies. The Sail SPRINGO EV is the first example.
As part of the plan, Shanghai General Motors is setting up a new energy products exclusive sales and customer experience in showroom; a new energy exhibition hall will be opened in Shanghai in the first half of 2013.
Shanghai GM is also planning development of hybrids; the use of SIDI direct injection technology and small displacement turbocharged engines; further development and application of advanced gearbox technology and brake energy recovery technology. In 2013, Shanghai GM will introduce Start / Stop technology.
In addition, Shanghai GM will promote the application of lightweight vehicle and other fuel-saving technologies, including the use of aluminum-magnesium alloys, lightweight acoustic materials, engineering plastics and carbon fiber composite materials.
