There’s a bit of an oil burner renaissance going on at this year’s New York Auto Show. Besides Mazda talking about Skyactiv Diesels, and Mercedes revealing a diesel GLK, Porsche also made news, displaying its Cayenne Diesel SUV in U.S. specification.
While it’s VW Touraeg counterpart is already offered with a diesel motor here, until now an oil burning Cayenne simply wasn’t available. Now that’s changed. Thanks to trickery such as AdBlue fluid injected into the exhaust and what Porsche called selective catalytic reduction technology, the 3.0-liter turbo diesel V6 is able to pass tough Tier 2 Bin 5 emissions standards and hence become certified for sale in the US.
