increasing hummers towing capacity

sweet rides... sweet paint job

your question has gotten more intersting.. looking at GM's website. the sierra 2500 HD can tow about 10000 lbs give or take, with a curb weight of 5100 lbs that means the engine can pull 15000 lbs. not bad

the yukon with same engine can tow about 9500 lbs with a curb weight of about 6000 lbs so the engine can pull about 15500 lbs. again not bad

then the h2... can tow 7000 lbs... but only weighs 6800 lbs...so the engine can pull in theory only 13800 lbs... what the hell???

it is not a gearing issue at least in comparison to the yukon both 4.10

ideas????

1) maybe GM feels that the overall aerodynamic 'footprint' creates around a 1000 pounds of drag at a decent speed... certainly not impossible

2) the yukon and sierra come with additional towing packages that have addtional transmission cooling and engine cooling stuff, could that make a difference

3) are the transmissions themselves different?


i personally think areodynamics play some role but certainly not the whole story.

ideas anyone..
