you also have to compare the power band & the peak power of the said vehicles.

for example:

Chevrolet Trailblazer 4.2 inline-6
275hp * 6000 rpm
373Nm * 3600 rpm

Ford Expedition 4.6 V8
232 * 4750 rpm
395Nm * 3450 rpm

the Exped's power is more accessible since the power peaks lower than the Trailblazer. though you have to see a dyno chart or test drive those vehicles to really see the difference. comparing in paper is sometimes futile.
