Axel Friedrich, a top German Environmental Agency regulator who advocates using modifications of existing vehicles as a more effective solution to the auto emissions problem. He recently reconfigured the VW Golf to show that by making changes- such as lighter seating and weight saving hood other steps to reduce the car's weight, low resistance tires, and engines that turn off when stopped and start when accelerator is pressed, more efficient gear ratios, removing the mirrors and substituting tiny cameras, and improving the aerodynamics- emissions can be cut 25% even with horsepower intact. Working with the Institute of Automotive Engineering at RWTH University in Aachen, Germany, Axel redesigned the Golf in this way to achieve a CO2 emissions reduction from 172 grams per kilometer to 131 grams and is working to bring it to 120 grams. 120 grams per kilometer is the EU's tentative target for emissions for cars sold in the region by 2012. Automakers have for years complained that this would be difficult to do in this manner because customers were concerned about safety and comfort. Its not clear that this would affect safety. However with global warming a big issue in Europe, most automakers are making changes now to prepare for a shift to 120 grams per kilometer in emissions. VW has announced a diesel version of the gasoline version that incorporates some of the redesign changes that Axel Friedrich made on his Golf, such as low resistance tires, and more efficient gear ratios, lower chassis for improved aerodynamics etc. This diesel version costs a base price of euros 20,615, and is only euros 315 mor than a standard diesel Golf. BMW has a new diesel version of its 1-Series with low resistance tiresand a gearshift indicator, which emits 16% less CO2 and costs nearly same as its predecessor. At Frankfurt Auto Show Mercedes Mercedes is expected to announce more cars with stop start systems. All this will help automakers in Germany achieve the EU 2008 target of 140 grams of CO2 emissions by 2008 on the way to the 2012 EU target of 120 grams.
