My firebird vs Trailblazer ?

So since I got my firebird, im like feeling all proud of my car etc and my step-father likes to bother me around and he is like "dont waste money on a car that I can beat with my family car trailblazer".

His trailblazer is an A/T with the 4.2L 6-inline engine with 291 HP SAE @ 6,000 rpm; 277 ft lb. My firebird is an stock A/T V6 3.8L 200 HP @ 5,200 rpm; 225 ft lb.

Lets say, in an straight race, since both cars are Auto, the driver is insignificant. Which car would win?

I am just having a hard time grasping the concept that a family car can outrun my sports car. And my step-father is all serious about it and willing to bet cash and all. Hehe.

Also, I have driven the Trailblazer and when taking off from street lights, getting the engine to around 2000 RPM is enough to get a *very* good acceleration while I have to get my Firebird to 3000-3500 RPM to obtain such thing. Why is this?

Thanks. Just trying to see your more expert and insightful opinion.

Re: My firebird vs Trailblazer ?

I think you would most likely win.
But I don't think you would beat it by much.

Weight plays a huge role here. Any idea what a trailblazer weighs??

Re: My firebird vs Trailblazer ?

The trailblazer has a curb weight of 2050 kg while my Firebird has 1509 kg. A difference of 500+ kg but the trailblazer engine is bigger and with 90HP more.

Re: My firebird vs Trailblazer ?

According to the numbers you gave, the power-to-weight ratios are as follows:
Trailblazer - .1414 hp/kg
Firebird - .1325 hp/kg

Looking at the pure numbers, since both are autos, your car is beat.
Is the trailblazer all-wheel drive?

Re: My firebird vs Trailblazer ?

not to mention the trailblazer has a LOT more torque down low, and thats what gives you the stoplight-stoplight advantage.. (since its mostly low rpm..)

Re: My firebird vs Trailblazer ?

Sounds like someone needs to invest in some bolt-ons...

Re: My firebird vs Trailblazer ?

Depends on what you consider BEAT. How well does a trailblazer take turns, or turn heads?

Even if he can beat you in a straight line race right now, the real waste of money is going to be feeding the extra horses under the hood of the SUV. Also the trailblazer is higher cost to maintain once they get a certain amount of miles on it and they start asking for parts.

Answer: Gear ratio and cam profile.

Re: My firebird vs Trailblazer ?

My mom had a 02 Trailblazer with the 4.2L and my dad was driving it one day when I had my 97 Firebird. We took off both launch it and first gear he was a little bit infront of me, but when we shifted to 2nd gear I pulled infront of him and when we shut it down I was I would say 3 maybe 4 cars ahead. But for a V6 sports car against an SUV, I say that SUV can run. My moms new Envoy with the 5.3L I'm pretty sure that would have beat me.

Re: My firebird vs Trailblazer ?

I drove a Trailblazer for a rental truck to go to Nevada. Man that horsepower is misleading, cause it was slow as balls. I could floor it and not chirp the tires. I think they over estimated the horsepower on those things. You should beat it easily.

Re: My firebird vs Trailblazer ?

I can chirp the tires in the trailblazer just as easy as with my firebird.

As I mentioned, the trailblazer has a lot of power with lower RPM and as someone mentioned it has to do with the gear ratios. The trailblazer has 3.42

Which one does the Firebird have?

There isnt a "set" one. Check your door codes

GU4=3.08's
GU5=3.23's
GU6=3.42's
