Tahoe Hybrid has more horsepower and more torque, however... Is it quicker than the regular (gas powered) Tahoe with the same gearing ratio?

I dont think so, the Hybrid system controls everything for gas mileage GM did not set it up for acceleration know it throttles it back on a nhard acceleration. Amost impossible to get any wheel spin. Plenty of power though just not ever going to get a good hole shot LOL

mine has first gen software
haha spin the tyres with TC on


if I was running at 3000-3500 rpm @v8 mode engine speed i'd hit 100-120 mph pretty quick that is what you guys run it at 80-85mph or so huh? on the norms or 3.73 or 4.10

2100 rpm is the cruse speed in v4 @ 80-85mph

theoretical the "top speed" is 145-155mph...

So first gen software is better? Did the subsequent software update tone it down?

yeah mine was the first few to roll of the assembly line jan 08 so it has the older software

the newer revised software have governed limits
other wise it will "take off" on you.. I can rev it to red line 6,000 RPM... :burnout:

they put the new software after the toyota prius scandal


this guy in a hummer yesterday tried passing me I just press the gas a little and zoomed right by him. he was probably at 3500rpm
while I was at 2300 rpm
those hummers have a 6.2L 393hp too so he was all ready in the power band

Super cool. How can one tell if the 08 still has the old software?

Also, is it possible to retro-tune the older software onto a newer Tahoe Hybrid?

Black Bear?

Ok so top speed is a factor indeed, but how about quickness vs speed. Are you saying the Hybrid can get 0-60 quicker than a regular Tahoe?

I know the Hybrid comes with an aluminum hood and lift gate to lighten the load, but is that enough to account for the extra weight of those two electrical motors to a point where it can zip to 0-60mph quicker than a gas powered Hoe?
