In an advertorial for Maserati, the Telegraph reports the results of a new study in which 100 percent of female participants had a significant increase in testosterone secretion (i.e. arousal) after listening to that particular sports car’s revving engine. (60 percent of men had the same response to a Lamborghini.)

“The roar of a luxury car engine does cause a primeval physiological response,” said researcher psychologist David Moxon, whose work was actually commissioned by a British auto insurer (i.e. insuring that people continue, despite economic downturn and concern about other kids of emissions, to buy luxury cars). He added the sound of an average car engine actually led to a decreased level of testosterone. Which, of course, is concern #1 when shopping for an automobile.
