H3 FAQ - Vehicle Comparison

[Wisha Haddan H3]

This table shows the HP and torque generated per liter in various engines.

It may be true that there's no replacement for displacement, but engine size doesn't tell the whole story. For example, the 5.9 liter Hemi in the Durango R/T is 4th largest in the list, but is dead last in HP/L and 2nd to last in torque/L.

Here's the same info in a chart sorted by HP/liter

How about something comparing the H3 to other SUVs similar in weight with 0-60 and MPG stats? Curious to see how other SUVs close in weight to the H3 make out in acceleration and MPG.

Good work! Keep it up!

Well, I don't have 0-60 times, but here's the MPG-weight comparison.

The results are fairly predictable, but they all get nearly the same mileage. I think it's hilarious that eco-terrorists (like the ones that race to cut me off in Boulder) hate the H3, but laud the FJC for its "better" gas mileage. They're usually the ones commuting 30 miles from their mountain cabins and running snow tires all year

The comment about 0-60 reminds me of a chart on acceleration I was working on last year. I was trying to develop a chart that would show a vehicle's ability to accelerate its own mass up a variety of grades in various gears. Crl 40% is crawl ratio up a 40% grade. 1st 0% is 1st gear x axle ratio with no grade (acceration from a stop). Crz 0% is the acceleration in the 1:1 gear with no grade (acceleration at highway speeds without shifting gears).

I can't vouch for its accuracy, I know the units are wrong, it assumes maximum torque is available immediately, it ignores the torque converter, and on and on ... but here ya go anyway.

Thanks for the info.
1) its a 2007 FJ Cruiser.
2) The 2wd man tranny version gets 21 mpg, 4wd rated at 19mpg I think.

My last tank of gas gave me just under 20mpg for a manual 06 H3. Average milage for 16K miles: just over 18mpg. I'll take it

Oops! Good catches ... I got the auto and manual mpgs backwards. All corrections are welcome

Yeah, I'll keep the H3 too. Not to mention, the FJ runs on premium. That's about $3.35/gal around here lately.

Well, from what I could find, the Alpha drivers that are getting only 12mpg are flogging the crap out of their rigs, driving 80mph. I can tell you that with my Duramax, driving 70-75 I got around 17mpg. On freeway trips where I took it easy at 60-65mph, I got just shy of 22mpg! How you drive it makes a huge difference. Again, a dmax pulling a big assed 5th wheel gets 12mpg.
