A new men's car magazine survey says men who drive BMWs have more sex than any other car user.

The survey of 2,253 motorists age 20 to 50 showed that BMW drivers have sex an average of 2.2 times a week, followed by Audi drivers, who reported having sex 2.1 times a week.

Volkswagen drivers ranked third in the survey, having sex an average of 1.9 times a week.

The survey was done by German car magazine Men's Car, which, according to television station WCVB, launched its inaugural issue this month and does not appear to have a Web site.

Ford drivers ranked fourth at 1.7 times a week, and pricey Mercedes-Benz came in at fifth place at 1.6 times a week. Porsche drivers reported having sex only 1.4 times a week.

A Cambridge, Mass., car rental company confirmed the popularity of BMWs among men.

"We've been amazed by the popularity of the BMWs in our fleet. We assumed it was the fine German engineering. Perhaps this explains it better," said Scott Griffith of the Zipcar rental company.

Among female drivers, French car drivers reported having the most active sex lives at 2.1 times a week, followed by Audi drivers at 2.0 and BMW drivers at 1.9 times.
