Mulling Mules

By Liz

This photo goes back in time about two years, in order to address something several readers have brought up. We’ve talked previously about “mules,” the test vehicles we use a lot in the early development of a future vehicle.

What’s A Mule?

In my last post, in response to some questions from readers, I wrote a bit about the use of camouflage on test cars. That got me thinking about another related aspect of testing future cars: mules, the ultimate camo.

We need to test aspects of vehicles long before we’ve ever built a full pre-production car. In a case like that, we have the ultimate camo. It’s called a “mule.” This photo shows what looks to be a regular Cadillac STS up on a hoist in a garage. In reality, these are “mule” versions of the 2008 CTS.
