A study conducted by British insurance company Hiscox reveals that the sound of a revving Maserati engine has a biological effect on women. Those who took part in the study listened to a variety of engine sounds from a number of cars, and after hearing the Maserati engine, all of the female test subjects had higher testosterone levels in their blood. High testosterone levels in the blood can be indicative of a stirred libido. (Or an insistent desire to try out for the Detroit Shock.) According to the study, of all the cars tested, the Maserati sound elicited the greatest testosterone response. Logically, to bring its stimulating properties to those who can’t afford a new Maserati, the company is now offering the engine sound as a downloadable ring tone for the cell phones of would-be Lotharios.
