About Us

If you're like most people, you know us for our testing abilities. No one has a more versatile tool box than we have and when it comes to product development support, there isn't much we can't do.

We conduct a wide range of engineering services, from full vehicle environmental testing, component testing, NVH and product engineering, to system or full vehicle simulation, crash simulation, data acquisition and customer correlation.

And OEMs and Tier One suppliers alike know that doing all their product development with one company just makes good sense; not only in terms of cost savings, but speed, efficiency and accountability as well.

So, as you can see, using Defiance just to conduct the testing is like using a high powered racing car for city driving. With well over 200 highly-qualified people, we're equipped to do much more.
