The shift from non-conventional polluting single cylinder engine contraptions used by poorer Chinese called "Inkfish" to conventional fuel efficient engines will reduce oil consumption in China even as more cars are on the road. This explains the paradox of Chinese vehicle sales being up by 77% year over year in the first quarter of 2010, and still gasoline demand went up by only 3%. Kack Perkowski, founder of Chinese auto-parts manufacturer Asimco Technologies, says the shift from the low tech "inkfish" type vehicles to fuel efficient small cars popular with the Chinese and encouraged by government policies to reduce oil consumption is a big factor in this development. Perkowski says 50 million engines are manufactured in China each year and if you subtract the 13.6 million cars, trucks and buses sold in China last year, another 36 million low tech highly fuel inefficient engines including "inkfish" engines were sold. China's car buyers are very price conscious and prefer smaller cars. Smaller cars are also well suited to the crowded roads in the coastal cities. And the Chinese government wants to keep oil consumption down so it is pushing buyers in the direction of smaller engines with tax breaks. The Chinese governmet is expected to announce subsidies for plug-in hybrids worth about one third of the sticker price. The motives are environmental and energy security related, but also have the intent of enabling China's car manufacturers to gain experience and leadership in newer electric car technologies. Bottom line: some experts including Deutsche Bank's Sankey view China's oil demand growing much slower, at about 2.6% a year over the next 15 years. This would mean oil demand tapering off at 13-14 million barrels of oil per day by 2025, much higher than the 9.1 million bpd in 2010, but growth curbed by fuel efficient engines and increasing fuel efficency of the Chinese vehicle population....
