Dale Earnhardt Jr. returned home Tuesday after an extended vacation in Germany, where he proposed to longtime girlfriend Amy Reimann and learned more about his family's German ancestry.

While visiting the European country, NASCAR's most popular driver took a drive out on the world-famous Autobahn, a highway where speeds are unrestricted in most areas.

So how fast did the third-generation NASCAR driver, two-time XFINITY Series champion and 24-time Sprint Cup Series winner go?

Well, there was no hiding it since Junior's new fiancee captured his speed in a photo she later shared on Twitter.

Junior's 210 kilometers per hour equals just a shade over 130 miles per hour -- far above the legal speed limit on U.S. interstates but much slower than the average lap speed at most Sprint Cup Series tracks.
