Automotive Security: Oops, far more complex than we thought

Thursday, September 24th, 2015


On a road trip with colleagues this week in Europe, driving about in a diesel-powered auto, it is with no small amount of interest that we have followed the news out of the U.S. regarding recently discovered emissions-reporting irregularities for diesel-engined VWs and Audis.

At the core of the alleged scheme is a cunning software construct that knows when the diesel engine should behave according to EPA regulations – in other words, when it’s being tested – and alternatively knows how to rev up engine performance by allowing emissions way in excess of allowed limits – in other words, when the car is being driven between testing sessions.

Whether you follow engineering, automotive engineering, the global automotive market (and stock valuations), or even international relations, you know that this story about VW is a complex one. And not one that is making anyone happy: Neither the company, nor the millions of owners of the vehicles involved, nor the governments and agencies in various geographies impacted by the revelations, nor the many whose health may be have been compromised by emissions that might have otherwise been avoided.

However, that’s not the point of this blog; the point here is one of situational irony.
