Cool news.
More changes sooner than later.
Keeps cars from getting stale.

 

A good sign of renewed vigor within the musty halls of Dearborn? Ford far too often lets a good design whither on the vine for too long, even the Mustang is showing a few wrinkles of time, though far from stale yet. Hopefully the redesigns will be better considered and executed than the B-team effort the Focus recently got, a clumsy pistache of just about every current styling cliche out there.

The article's Flex example was good -- a fresh 2005 concept finally straggling into the showrooms nearly half a decade later. Such a compelling design should have hit the road as a 2007 and be slated for its first freshening in '10.

 

I've read here that the 2010 Mustang refresh styling was already being worked on in 2004, before the S197 was even out on the market.

The Ford GT was shown as a concept at the Detroit Auto Show in 2002 and production models were delivered in the fall of 2004, but that was not exactly a regular production car.

So which automaker consistently gets a brand new product from concept car to production in two years?

 

Dodge Challenger, for one - though that doesn't really meet your definition of consistent, I suppose.

But it does prove it can be done when there's a will to do it.
