Now you're just being silly. What about the LS 6.2 at 420 ponies? :R

On second thought, maybe you were right. GM doesn't make a V8 that can keep up with the EB; with 420HP it will not keep up; it will be so far ahead that they will forget the EB was even in a competition. :B

You mean this 6.2 that barely beat the 3.5 ecoboost. The 420/460 numbers look good on paper.

GM 6.2 tow test

The majority of Americans don't live at high elevations. That compares a turbo engine vs a naturally aspirated engine at 11k feet above sea level. Not exactly a scenario that applies to 95% of truck buyers on a daily basis. Secondly for whatever reason the chevy wouldn't hold a downshift. If they would have manually selected 2nd and held it to the floor it probably would have done ok.

At lower elevations and manually selecting the gears the 6.2 chevy will eat the ecoboosts lunch. I think the highest elevation my truck has seen and is likely to see is probably about 3500 feet. I really couldn't care less what it can do at high elevation.


EDIT: Just watched the link and realized it wasn't the ike gauntlet tow test. Anyways it was still done at higher elevation and with the amount of torque management they put in modern trucks full throttle from a standing start isn't the best comparison of how much power is available for normal towing use. I rarely if ever leave a stoplight at full throttle towing or otherwise. If you want to talk which will hold the most speed up the majority if grades we will encounter towing I think the 6.2 has the edge.
