2003 Avalanche 5.3 top speed = 100mph.

5 mpg?

8... and it handles like a Conestoga wagon

I've done 170 km/h (105 mph) in a Suburban...

Would anyone believe me if I said the Cutlass hasn't seen speeds higher than 70 mph?

I did finally the break the rear wheels lose without the help of water or gravel, though. I didn't think it was possible with all the more power it has.

Calculated modified '59 Buick : 143

I'm guessing I was electronically limited because it just went up to 100 and then stopped accelerating.

Yup, that's the electronic speed limiter. GM trucks are set at 100, I think, or thereabouts. Fords are set lower... I had heard about this, but found out firsthand on the Northeast Extension of the PA Turnpike. :AH-HA_wink:

100? That doesn't sound right. What engine and gears are you running?

it's electronically limited.

I once hit the speed limiter in a '95 Chevy K2500, at 105MPH the computer shut me down.

Damn computers! I've had mine my Av up to 100 before the long arm of the software pushed my right foot back up.

Chevy now lets an option of limiting the speed to 70mph on the 2008 Silverados.

A conestoga wagon? I would like to own that horse. What a shame about George Washington.

Besides your well being, in a worst case scenario what would an Avalanche going 100+ do to the people riding in a Cobalt or Corolla?

Thanks for sharing.

yeah i flashed my 02 sierra but really haven't pushed it past 100. your right abouts its handling though.

Wow, I thought @ 100mph GM Trucks would handle like the Z06 ? (stupid GM).

The '95 handled just fine.

As someone who owns a Corvette (not a Z-06) and a GMT900, I can tell you that the Av had good feel at 100 mph, not like the Corvette, but I wasnt afraid at such speeds.
