Gary Powers proclaimed:
With a suitably modified engine, it isn't that overly heavy. However, I would expect the 4 wheel drive to be a disadvantage since a good launch for drag racing typically involves wheels leaving a bit of expensive rubber behind. Perhaps am wrong, but on a 2wd always got best street starts with a bit of cop alarm squeal.
Or perhaps he has a Grand Cherokee SRT-8, where even the non-SRT version is a bit quicker than a midline Bimmer.
Geoff proclaimed:
A lot of this is due to the startle factor...plus really really good low end torque, typically more than a smaller buzzier motor can generate in that first critical few feet or so.
Make it an endurance race- the krautmobiles will fall to pieces before the Jeep :-p
Escalade = big fat pig. And the 5.9 Magnum with the mods mentioned has "alot" (sic) of power too.
Heh heh heh... here's another sucker for you guys... :-)
Don't forget the setting: 1/8 mile drags. Torque rules, "sports cars" drool.
griffin proclaimed:
More like dry lightning. Smokable by a Grand Cherokee without even working up a sweat. Plus you can always tow 'em home with the Grand after they crap out.
Lotsa power !=fast. Lotsa power + low weight + gearing = fast
Can't see it remotely.
Both cars weigh almost exactly 4000lb.
The GC has puts out 245hp from its 5.9 litre V8, and 335 lb/ft torque. It does 0-60 in 7.3 seconds. That's 41 bhp / litre. It has a 4 speed auto.
The M5 puts out 507 hp from its V10 engine, and 383 lb/ft torque. It does 0-62 in 4.7 seconds. That's 100 bhp / litre. It has a 7 speed auto. De-retricted, it will reputedly do almost 205 mph

Or 335 hp with 375 lb/ft from 5.7 litre, which if not enough can be also had with a blueprinted 6.01 hemi of 425 hp. And that is without getting into the crate engine upgrades possible.
Could swear even the older grand has a 5 speed with the V8.
Even the hemi versions are restricted to about 115, to help keep alive the doofii unable to tell the difference between an SUV and a Porsche.
As for 0-60 times, they don't always map that well to the 0-30 times where low end torque, gearing, and traction count.
I'd honestly still have to put my money on the M5 ...even the 1/8 mile. I've seen the M-series first hand and have rarely seen any stock vehicle take them except for musclecars. They shift incredibly quickly and stick to the ground very well. See if you can arrange a race with an M5 and lemme know how it goes. I'm really curious!

Some of the benefits of where I work is a collection of non cash-strapped motorheads and a mile of fenced off dead-end road. :)
I've pitted the ZJ against an M5 and lost. While not as quick as the 240ZX Twin Turbo which smoked my ass even after a five car length head start, the M5 hauls. Honestly I'd love to fit the ZJ with a more current 4 or 5 speed auto.
Of course I challenged my friend to a race over the parking blocks but he forfeited that one. So we called it even. ;)
griffin proclaimed:
OK, all kidding about the impossible task of beating an M5 with anything other than a heavily modified Jeep, sure--if I get to pick the road--or lack thereof.
A Grand is surprisingly quick off the line, but still wondering how to get a truly fast launch without wheel slip.
Lon did pass the time by typing:
.practice. :)
Sticky tires help too. Apart from breaking them loose in a turn or adding a bit of bleach, I could never get the Pirelli Scorpions to smoke.
Any car can beat my 2.5 93 yj, but when the road ends, and the car also....I can keep on going. :) Nick
Unless you're racing on ice, it wouldn't even be a contest. The M5 would be LONG gone, even in a 1/8 mile race.
Horsepower is irrelevant in a short acceleration contest
At what RPM? (hint: LOW, where it counts, and where the 4-wheel drive can apply it to the asphalt)
Who cares- HP/liter makes good ad copy, but doesn't mean s*it in the real world. Otherwise, the Viper wouldn't kick a Ferrari's ass.
irrelevant- see above.
At what RPM? (hint: a hell of a lot higher than the 5.9 hits its torque peak). Stupid high-revving squirrel motors....
Who cares? The race was over at 1/8 mile and well under 70 mph. Of course the Jeep can pull the M5 off the tree that the idiot driving it
200 mph wrapped it around, too.
The hemi puts out that same 335 hp at about 2300-2400 rpm...and that is just the standard hemi.
KokomoKid proclaimed:
Feh. Ice not needed. Good old fashioned snow, sand, wet alkali, or speed bumps are good enough.
The only figures I can find for the 1/8 mile for the BMW M5 are 8.227 seconds 87.360 mph. Anyhow, I'm bored of this now.. believe what you will.

A pissing contest...

yes, but sometimes they are fun.
jeeps are made to run in the roughstuff, so who cares how fast they get there. old john
