Cubic inches matter. Loud car engines can activate a woman’s sexual arousal, according to British researchers. Women who listened to the revving engines of Ferraris and other high-end cars showed elevated testosterone levels, indicating sexual excitement. The throaty roar causes a response in a woman’s hypothalamus, triggering physiological arousal, says lead author David Moxon. But don’t redline a Civic – the noise of a four cylinder car lowered women’s testosterone levels.
