There is an fantabulous thread here (Understanding Power, Torque, Gearing and Top Speed)on knowing Torque and BHP. (Mods you whitethorn merge this with the aged thread if it fits).

I americium trying to recognize however numbers connected insubstantial construe to existent life. (of course, determination is the value of the vehicle, gears and its handling dynamics etc).

For example, I precocious trial drove the Jeep Grand Cherokee successful India. It has a 2 litre turbo charged petrol motor producing (as per Jeep India website) 268 BHP astatine 5200RPM and 400NM of torque astatine 3000 RPM.

The thrust itself felt spirited and zippy connected a level roadworthy for a 2097 kilo car (I was surprised). How volition it enactment connected an uphill roadworthy with 5 adults successful the car, their luggage and AC running? Will it beryllium (almost as) effortless arsenic compared to a Ford Endeavour 3.2 Titanium with 200BHP and 470NM and 2400KG?

I drove the Jeep Meridian 2 litre diesel instantly aft that, and the thrust felt sluggish and afloat of effort arsenic compared to the Grand Cherokee, I felt I had to property the motor harder to determination zippier and it was astir apt noisier arsenic well; (this could beryllium a relation of dependable insulation).

Although astir cars get the occupation done (I person seen Altos scurrying on successful Kaza, afloat loaded and all), for hard halfway driving enthusiasts, we look for driving pleasure. We look for the feeling of a surge of power. We privation to beryllium capable to thrust effortlessly up winding ghats, afloat loaded with ACs connected successful afloat blast, and to person capable reserve powerfulness to rapidly overtake dilatory moving trucks (safety and lanes permitting) successful abbreviated speedy bursts of velocity and power.

How overmuch of the zipper feeling is besides a effect of the tuning of the motor (+gear etc combo) to nutrient much power/torque vs tuned for mileage successful a terms delicate segment?

Grand Cherokee dashboard was suggesting astir 5-6kmpl and Meridian would beryllium overmuch higher of course).
