True! diesel vehicles are tuned for torque and petrol vehicles are tuned for horsepower....but cars usually have a higher rev band than other vehicles
dude! i have tried this...and i have seen other people also doing it....what wikipedia says is correct...but that doesnt mean its only used for that purpose........if you search for "headlamp" in wikipedia...it'l say "A headlamp is a lamp, usually attached to the front of a vehicle such as a car, with the purpose of illuminating the road ahead during periods of low visibility, such as darkness or precipitation"....but dont you sometimes use headlamps as mean of communicating with other drivers in front of you such as to "stop"???
