Subaru's Symmetrical All-Wheel Drive System
Subaru's symmetrical full-time All-Wheel Drive system is the fruit of many technological advances aimed at ever-improving the performance of Subarus on the road. By constantly adjusting torque distribution to front and rear wheels, the symmetrical integrated drive system improves performance, ensures better road handling in even the most extreme conditions, and makes life easier, safer and more enjoyable for every driver, in all situations.
The symmetrical integrated drive system is at the heart of the technical innovations which have made Subaru a legendary name in FIA World Rally Championships, and it's also what carries your own driving experience to a whole other level.
With a simple and affordable technology which has no more incidence on your wallet than on the performance of its cars, Subaru has been able to perfect vehicles whose smog-generating emissions are practically nil. Available on the Subaru Legacy and Subaru Outback, the exclusive-to-Subaru PZEV technology allows you to claim bragging rights to owning the cleanest gasoline-powered vehicle on the market today.
The Outbacks and Legacys equipped with PZEV technology are Smartway-certified by the U.S. Environmental Protection Agency (EPA), and meet California's strict air-quality standards, the most stringent in North America. Emissions produced by PZEV vehicles are 90% cleaner than the average emissions of new automobiles. No complicated and expensive technology here, and no effect on performance - only immediate ecological benefits.
