GM unveils new 6.2 1/2t specs

1.5 seconds faster on the second try, was he going down hill. The Ford and Ram should got a second chance. The Ram sounded like it was geared really high in 1st gear.

Others may say differently but the fact is if you have that kind of HP going to the rear wheels either the traction control will kick in or if turned off you are going to spin the wheels if your not careful. I don't care if you have 1200 lbs in the bed or 1000 lbs on the tongue 400+ ponies is more than enough to break the tires free.

Who care? What kind of fool races with a loaded trailer?

The test was GM biased. You wouldn't try to out run somebody with a trailer?

This trailer weighed approx, 5000 lbs so probably around 500-600 tongue weight. In this example you may be right about spinning tires off the line but past that I doubt it is an issue.

Now the 1200 pound payload in the bed is a different story. I highly doubt the 6.2 liter is capable of spinning the tires in this example. Just too much traction on dry pavement.

I guess you are under a different impression of the purpose of this test than I am. I see it as a cheap and easy way to compare how well a vehicle can get power to the ground in a real world example. Another way would be to test each truck on a chassis dyno but those too aren't real world since transmission shift points are usually manually selected and lack of airflow for cooling and wind resistance. I see it as valuable information and I only race my truck unloaded.

You can't tell me if a Ram or GM pulled up beside you at a stop light and you both had a load on you m wouldn't try to outrun him.

As these trucks have gotten more and more powerful the mfg's have programmed in some "power ******" into the programming. Stock, my V10 F250 with 4:30 gears would barely chirp the tires. After adding a programmer, that removes this "power ******" it will light them up. I rarely abuse my Michelins like that but I promise you it will spin the tires no matter what is in the bed or on the hitch!

On edit, this is mainly on the drive by wire trucks.

Your are right, one some drive by wire vehicles you are not getting full throttle at lower RPM's. I think in some cases they do this for marketing. In the case of your truck they probably did to help sell a diesel. The 5.0 Ford is like this, I think they did it to help sell more ecoboost.

Main reason is to protect the drive line.
