Porsche uses Diesel Exhaust Fluid (DEF) to bring Cayenne Diesel to the U.S.

Christopher Goodfellow - 10 April 2012

Porsche is launching its Cayenne Diesel in the U.S. with the 2013 model year, which meets Tier 2 BIN5 emissions standards using Selective Catalytic Reduction (SCR) technology and Diesel Exhaust Fluid (DEF).

The Cayenne Diesel has been available in Europe since 2009, but had not previously been able to meet U.S. emissions standards. It will go on sale in September at a base MSRP price of $55,750, not including a $975 "destination charge", according to a statement from the company.

The Cayenne Diesel is powered by a 3.0-liter V6 turbo diesel engine, delivering 240 horsepower and 406 lb. ft. of torque from as low as 1,750 rpm. The result is 0-60 mph acceleration in just 7.2 seconds and a top-track speed of 135 mph. The Cayenne Diesel can travel up to an estimated 740 miles on a single tank of fuel.
