|A Hyundai Accent|
Hyundai Motor (HMC) chose the Guangzhou International Automobile Exhibition as the venue for its unveiling of a mild-hybrid version of the Accent sedan, due to go on sale next year in Korea as a 2007 model.
Hyundai said earlier this year that it would advance sales of hybrids in the US to late in 2006, starting with hybrid versions of its Accent and the Kia Rio. Hyundai has developed its hybrid technology itself, working with Enova, in which it has a stake. (Earlier post.)
The Accent hybrid combines an Alpha II 90 hp (67 kW) 1.4-liter CVVT (Continuous Variable Valve Timing) gasoline engine (also used in the Getz) with a 12 kW permanent magnet synchronous motor integrated between the engine and the transmission. The engine delivers 126 Nm of torque; the electric motor delivers 80 Nm torque.
The engine is downsized from the 110 hp 1.6-liter top-end gasoline engine found in the conventional Accent. According to Hyundai, the Accent hybrid offers fuel consumption of 5.29 liters/100 km (44.5 mpg US). Acceleration from 0 to 100 km/h takes 12.2 seconds.
The design is a mild hybrid—the motor assists the engine, supports regenerative braking, and handles idle/stop functions, but is not capable of powering the vehicle in electric mode alone.
The company is buying its NiMH batteries from Panasonic EV Energy Co., the Matsushita Electrical-Toyota joint venture that supplies the batteries for the Prius. The Hyundai hybrid drive uses a 6.5 Ah / 144V battery pack.
Hyundai officially unveiled its hybrid vehicles 2004 and has been testing and producing them in limited numbers in Korea. HMC sponsored Korea’s first official hybrid pilot by providing 50 Getz hybrids to the Korean Ministry of Environment in October 2004.
The project is to last for 3 years, and calls for the testing of HEVs along public roads in the Seoul metropolitan areas. The Getz hybrid uses a similar hybrid drive, but with a 1.5-liter gasoline engine.
The company has announced that it plans to develop and manufacture a Sonata hybrid by the latter half of 2007.
