BMW Brake Test

how about you throw in the fact that a formula car weighs almost 1/3rd of that of most normal cars, not to mention brake brake diameters are about what 3 inches larger than the already large 14 inch brake rotors on an m3, most cars have around like a 10-12. Also factor in the stickier tires used on formula cars vs an M3 (which are already ultra high performance tires for everyday use). Also the things the other's mentioned, you get a 32meter difference, compared with most other cars, it would probably be more like a 40-45m difference. I'd like to see a comparison braking test against the SLR, Enzo, Zonda, and Carrera GT. To see where the world's top of the line cars hold up against F1

i think the demonstration is to show how well the BMW brakes. It's quite a showing actually that the BM2w at speed slowed and stopped as well as it did. There are several things to take into consideration when trying to analyze this video. Unless you have ever changed the brakes on either car you really have no concept. As a mechanic specializing in brakes and suspension on foreign cars i can tell you that bmw and mercedes have about the best braking performance and system of any touring car. Now, that being said, Ferarri and Lotus and a few others use a race inspired braking system very similar to F-1. 4 piston calipers, ceramic pads, slotted and ported brake rotors plus a brake proportiner valve that distributes brakin evenly to all 4 wheels. ( or can be adjusted for different brake bias settings) not to mention the suspension on the F-1 is absolutely rigid where the BMW plows under heavy braking even with computer controlled abs. Front engine versus mid engine. vehicle ride height . Tire size and type are a big contibutor to the differences.

Ths video teaches one thing. Buy a F1 car.

Who gives a crap?

Why would a lighter weight car with larger brake discs stop faster??? ....um maybe physics...

Formula
cars are really light, have a 8 liter engine that stil pumps out 800 hp (That insane for such a small engine) and it obviously has good brakes(Its a racecar...idiot).

mbw very goooooooooooood race

Use the BMW against nascar, or some other full bodied race car, something close in weight. Honestly, this doesnt prove squat to me.

Just if anyone thought this was an M3 in the video it's not. Check the front spoiler, wheels, door mirrors, no flared arches or side vent on the front fender.

Actually, the wheels on a F1 car are just over 14" (360mm) in diameter, and the brake discs a little over 11" (280mm). The rear wheels are actually wider than they are tall. Most people don't realize that given equal weight, a car will accelerate and decelerate faster with a shorter wheel since it concentrates the mass closer to the hub.

poor guy, who will be hit by that car

but the center of gravity is higher in the BMW, which makes it less stable when braking. because of that, the brakes are designed so that they don't lock, which decreases the chances of spinning out of control, as well as avoid damage (having your brakes melt to the tire). all in all this wasn't a particularly fair test.

WoW

with my car it would take 2 full rounds to the track to make it brake: it doesn't have ABS, it has E.W.B.S (Eventually Will Brake System)
lol

F1 has Better Brakes? So we should all drive a F1 on the Road to go Shopping, to reduce the Numbers Of Accidents?

quote Ipod100: "have your brakes melt to the tire"
uh... how in the hell is your brakes going to melt to a tire... unless u put them right next to eachother and took a blow torch and melted them together... no way in hell will the brake melt to the tire... theyre not even connect to eachtoerh... he knows a little of what he's talking about, but a moron for that statement alone. this high center of gravity stuff is true, but u gotta take one thing into mind. F1: professional grade ceramic brakes BMW M3: non profressional grade brakes... difference in grade, quailty and let alone, strength... this is only a show of how great an F1 car is in controlling its speed...
