Is the rated towing capacity reduced at higher elevations with the turbo engine? I live at about 6000 ft and travel to 8000 ft quite often. I almost bought a Honda Ridgeline until I found that its towing capacity was reduced 3% for every 1000 ft of elevation. The Ridgeline is rated to tow 5000 lbs at sea level but only about 3800 lbs at 8000 ft. I was told this was because non turbo motors lose power due to the thinner air in the mountains while turbo motors do not have this issue. Supposedly the Ascent with the turbo will have more horsepower and torque that the Ridgeline at high elevations. Also the turbo engine rpms will be noticebly less due to the much flatter torque curve. Without being too technical is this really true?
