Nissan Motor Co., Japan^s second- biggest carmaker, said it^s developing components that can draw more battery power to run motors, part of an effort to make vehicles that burn less fossil fuel and boost efficiency.
Nissan^s Super Motor, lithium ion batteries and inverters may nearly double the acceleration performance of vehicles that run on fuel cells, gasoline-electric hybrid engines or electricity, the Tokyo-based carmaker said. The system may be ready for use by 2009, said Executive Vice President Mitsuhiko Yamashita.
Nissan is aiming for a new system that ``may be more efficient, high-powered and compact than the ones in the market today,^^ said Credit Suisse^s Tokyo-based analyst Koji Endo, who rates Nissan ``outperform.^^ ``The new electric system may be used for Nissan^s future hybrid and fuel cell vehicles.^^
The surging price of gasoline has pushed Nissan to look at alternative power sources as part of its record 450 billion yen ($3.8 billion) investment in research and development last fiscal year to close its technology gap with Toyota Motor Corp. and Honda Motor Co.
Nissan^s Super Motor and lithium-ion batteries will be up to 35 percent smaller and lighter, and 30 percent cheaper than conventional systems. The inverter, which regulates electricity used in a car^s engine system, will be 30 percent cheaper and 20 percent smaller with double the power, Nissan said.
Nissan will introduce a hybrid version of the Altima sedan in the U.S. as a 2007 model. The carmaker will be buying 100,000 units of the hybrid system from Toyota over the next five years.
``We are looking at developing more of the components^^ before Nissan considers selling a hybrid engine system of its own, Yamashita said in an April 3 interview in Tokyo.
Price Gap
The hybrid Altima will be sold to help Nissan meet regulations, instead of selling it for business reasons because the cost of the gas-electric system is too high, Chief Executive Officer Carlos Ghosn said in January, without elaborating.
An ``appropriate price gap^^ between a hybrid vehicle and one using a conventional gasoline engine should be about 200,000 yen ($1,700) in order to popularize the gas-electric version, Yamashita said.
The hybrid Altima won^t be profitable for Nissan to produce at least in the first five years of sales, Ghosn said.
``I am not enthusiastic about hybrids,^^ Ghosn said in January at the 2006 North American International Auto Show in Detroit. ``I hate selling cars at a loss.^^
Shares of Nissan, 44.3 percent owned by Renault SA of France, fell almost 1 percent to 1,390 yen in Tokyo yesterday. The stock has risen 16.3 percent this year, outpacing the 6 percent gain in the key Topix index.
Tino Hybrid
The carmaker^s attempt six years ago at selling a hybrid car wasn^t profitable. It made 100 units of the Tino wagon, selling it for 3.15 million yen, 40 percent more than a conventional model.
The Tino wagon was run on Nissan^s Neo Hybrid system, which combines a lightweight lithium-ion battery with a gasoline engine. The system improved fuel economy by more than twofold while cutting carbon dioxide emissions by over 50 percent, Nissan said.
The hybrid^s ``cost is still higher than what customers are expecting to pay,^^ Yamashita said. ``But we can^t abandon this technology just because the cost is too high. We are working on solutions to cut costs.^^
Global sales of hybrid vehicles were 0.5 percent of the 62.2 million new cars, light trucks, vans and wagons sold last year, according to an estimate by Hirofumi Yokoi, a Tokyo-based analyst at CSM Worldwide, a consulting company in Farmington Hills, Michigan.
A hybrid vehicle combines a gasoline engine with an electric motor. At low speeds, the motor powers the vehicle and the gasoline engine kicks in as the car gains speed. The battery pack for the motor is charged by the gasoline engine and by power regenerated whenever the brake is applied.
Research Budget
The maker of the Z sports car raised its research budget by 15 percent every year since 2001, turning record profits into investments to catch up with Toyota, while U.S.-based carmakers General Motors Corp. and Ford Motor Co. are closing factories and slashing jobs to improve their earnings.
``This tendency will continue in the coming years, but this will depend on what kind of advanced engineering we are going to do and how many models we will be releasing in the market,^^ Yamashita said.
Nissan, with 17,700 researchers out of its global workforce of 163,686, has been hiring 10 percent more development staff every year since 2001. Development cost may reach 5 percent of last fiscal year^s total sales of 9 trillion yen, up from 4.6 percent from the previous year.
