Which car do yall think would be faster in a highway race?? I remember a guy on z06vette.com said he raced his friends E55 AMG and everytime they were even until 4th gear when the Z06 started slowly pulling away. Now when I saw the 507 HP BMW M5 race a E55 AMG(streetfire.net) from a roll the M5 pulled on the AMG pretty easily. Personally I think a race between the C5 Z06 and the M5 would be interesting. What about yall??

 

German high performance vehicles tend to be tuned on/for the autobahn. That means Watch out at high speeds... on the other hand, I can't imagine the M5 has the aerodynamics of the C5 either.

My total bench racer guess would be that the z06 would be faster in the 100-150mph range, but that the gearing and sheer hp advantage of the M5 would give it the advantage at 150+.

 

405hp V8 Z06 507hp V10 M5 from a roll all day long.
Weight doesn't make a big difference on the highway and all the aerodynamics in the world ain't gonna make up for the power difference.

 

2006 Z06 vs V10 M5 would be interesting.

 

Actually, at some point (maybe very high speed) the drag coefficient will more than make up for it. If you know both the drag coefficients you can take a pretty good guess at that. Weight definately matters. It's not like the power to weight ratio changes just because they are moving. The Z06 will definately own the M5 in the 1/4 mile but I agree with the first post. Interesting race up top.

 

video tape it and post it up

 

If your talking c5 z06 against an e39 M5 then the z06 will take it everytime. I used to have an e36 m3 so I spent a lot of time over at bimmerforums.com and still do. This has been discussed numerous times over there. A member on there owned a c5 z06 and then e39 M5 and he says the z06 was much faster. Of course the m5 is no slouch lol. I believe the same results would follow with a c6 z06 against an e60 m5.

The usual comparison is against ls1 f-bodies vs e39 m5's and its usually very close until high speeds when the m5 creeps away.

 

weren't the old M5's rated at 394hp? and doin low 13's in the 1/4?

 

Yeah low 13's and as fast as mid 12's I believe. The fastest M5 Ive ever seen was a twin turboed e34 making 1200hp and did the 1/4 in 8.8.

 

DAMN

 

There'd be no contest: the C6 ZO6 would have this one in the bag from the start.

 

New m5s actually have top speed of 210mph or something, so those cars must have pretty good aerodynamics

 

Drag CO mean sqaut with out frontal area. A house brick has a worse CO than a Corvette, but due to being only a few inches wide it has a much lower drag.

The Z06 has worse CO than a regual C5 due to the rear window design. The BMW is bigger, but I bet there ain't that much in it.

STOCK for STOCK at speed the BMW would murder a C5 z06. Remember it has SEVEN, yes 7 gears, all sequential and can change gear quicker than you can blink!

From a dig it could be close, but the BMW does have a better 0-100mph time than a new C6.

 

It's true the power to weight ratio doesnt change.... but where the weight has the biggest impact on a race is on the launch, when the car is trying to overcome inertia. Once you get rolling the impact is less.

I would vote for the C6 Z06.... Would be an interesting comparison, and aerodynamics have a huge impact at those speeds. ask my buddy with the lightning. He experienced the effect of aerodynamics when running the 1/4 after he started to mod. Diminishing returns is a beehotch.

Oh and after 155 the vette will walk the M5 :> BMW handicapped the car themselves. Not sure why.... maybe the same reason MB wont lift the speed limiter on the SL line... heavy cars like them have a tough time finding tires that will hold together at extremly high speeds.

 

I disagree. M5 would not murder C5Z, so what it has 7 gears and can change gears quickly, many humans can as well. If you want to talk about limitations, M5 is limited to 155 mph, C5Z can go much faster.

We are not talking about C6 and C5Z has better 0-60 and 0-100 time than M5.

 

The M5 was limited to 155 but it's capable of 200+ mph. Now if the is race from a dig the advantage goes to the C5 Z06 but from a roll I think the Vette might get pulled. Still if there's any car in the world I could have I'd have the V10 507 HP BMW M5. I mean it's the ultimate machine to me.

 

seven gears, means it has a better ratio, so it will deploy the power quicker, like changing the rear end gears do.


There are NO humans alive that can change gear any where near as quick as a sequential box does, don't kid yourself about it!

possible but it can't be by much, in fact almost nothing. In a recent test the M5 not only matched a Ferrari F430 in accelaration but on a cross country route the BMW was the quicker!

The BMW will do 0-150mph in 21.5 seconds.
A TVR Sagaris which is quicker than a C5 Z06 does 0-150mph in 21.0 seconds.

 

That 0-150 in 21.5 secs just shows how this thing just gets stronger and stronger as speeds increase. Btw the C6 Z06 does 0-150 in 17 secs so there's no comparison there.

Here's a link to the 507 HP BMW M5 racing it's rival the Mercedes E55 AMG:

This race just shows you how nasty they are from a roll. The E55 AMG has way more torque than the M5 but it doesn't matter.

 

lol, yeah that's pretty SLOW, no comparison.

If you mean 17 seconds 0-150mph, that is impressive. Almost a llittle too impressive if I'm honest.

 

We could sit here present our opinions, throw out stats to fit our arguments all day but it's all moot point until there are two competent drivers racing eachother in various speeds.
