In case you needed to know....

2003 Avalanche 5.3 top speed = 100mph.

[CARBIZ]

5 mpg?

[Drew Dowdell]

8... and it handles like a Conestoga wagon

[the_yellow_dart]

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

[Cory Wolfe]

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.

Stock '59 Buick : 122

Calculated modified '59 Buick : 143

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

[ocnblu]

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:

[Drew Dowdell]

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

it's electronically limited.

[Camino LS6]

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

[K.C.]

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

[Z-06]

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

[FloydHendershot]

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.

[capriceman]

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

[Casket Demon]

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

[Camino LS6]

The '95 handled just fine.

[K.C.]

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.
