recently i've heard that hydrogen fuel cells or some form of electric motor must eventually replace the gasoline engine in the next 20-25 years since gasoline occurs in a limited supply. interestingly, the few cars that already have these technologies have been shown to produce practically no engine noise. though this may be ok for economy cars, having no more distinctive engine noise may ruin a huge part of the sports car experience. imagine never hearing the racecar-like wail of a ferrari v8 or the monstrous growl of a lambo v12; it would be like taking away a part of the very soul of sports cars!!! has anybody else considered this possibility????
