stock M3/M4 quarter mile prediction

[pkimM3r]

I was just curious about the all so "fast" tesla S.

12.3 1/4 time with trap speed of only 110mph?! I thought that thing was fast. Add just a little more distance and even the current m3 is blowing past it (trap speed 115-117). Am i correct?

And they say it kills the performance of the f series m5/6.

From a stop, it's going to be ahead for quite some time. Not sure what the 60-130 is for the P85, my guess is not very fast.

The only video we've seen online is the obviously [personally]] rigged vs. the F10 M5.

I am hoping the F80 M3/4 will destroy it long before the 1/4 distance, like this CTS-V with 11.75 a@ 120mph.

Beginning doesnt really much matter as the guy in the tesla will be thinking wth hes slowly gaining. No wonder i (a track noob) was seeing a tesla (driven by an instructor) disappear from my rear view on the straights.

The Tesla S has come a long way from the Roadster in terms of track day suitability. Having no gears and max torque at 0 RPM is an advantage. The car can easily do 100 minutes of track time in a day. Caveats: no engine noise is weird in a hot pit, power is reduced by about half when you are below 25% battery, and you won't have enough juice to get home after the track day (hotel overnight stay on Sunday).

Yeah but looking at trap speeds it sure does seem that it loses a lot of its acceleration in the top end. Eg m3 does what, high 12s at 116mph while the cla 45 does the same but at 107 and the teslaS at 110. Especially in long straights where you can easily hit 150ish, it will be sluggish no? And it does weigh 4000lbs and is limited to 130mph? (I may be incorrect i realize.)

I don't know much about European 1/4 mi testing specs, I think they more often do 0-1000m.

No, I was more looking at trap speeds as I'm not big into 0-60 times. Take the Roush Stage 3 which has Ford factory backing. "575 bhp" and yet runs a 114mph quarter. Seems to happen a lot with Ford and Dodge in particular, Evo often makes note of it.

Interesting to hear about the different testing standards though. I did know that, but it explains some results now that's for sure.

BMW has been making cars since Nazi Germany. Tesla has been making its own original car for only a year. It is an incredible accomplishment that a family car with the practicality of a Dodge Caravan powered by batteries and weighing more than a Bentley Continental Flying Spur can do this so well. The Tesla S beats the pants off an E39 M5, which was the fastest supercar anyone had ever heard of no less than 8 years ago. I think those cars barely break into the 12's for 1/4 mile.

It is amazing the progress we've seen in the last decade. It wasn't too long ago cars doing 0-60 under 6 seconds were considered fast. I remember thinking the 333hp M3 was so powerful in the not too distant past. Now a normal person can buy a car that can run circles around the 'supercars' of 10-15 years ago.

M3 is high 12s at ~112 mph, not 116.

oops, i was doing it based on recollection of an earlier thread and post. But, shows how much I really care about 1/4 mile times.....most races are longer than that!

However, you can't have an opinion on the relationship between power and torque. If a car makes 450 ft lb at the wheels (at say 5000 rpm, which is consistent with the engine curves we have been shown) that translates to 428 wheel hp which is 486 crank hp (assuming a reasonable 12% loss). Which is it 380 wheel hp or 450 wheel torque? The latter would be easily capable of 11.X second runs.

No you're right, I didn't do any math for that one sorry. The horsepower figure is what I will choose to go off of. I highly doubt that they'll have a stocker putting out 450 rwtq. They might do it, I just doubt it! Also of note, the transmission can have a huge play in the quarter times. DCT etc... I just don't see them making a sub 12 sec car, not saying I won't be impressed or pleased with their progress if I'm wrong!

This thread came up searching for M3 quarters; curious if anyone's seen magazine results yet or has vids to share.

I defected from my mid-14 sec E36 M3 to 12.4 IS-F when the M3s tanked fuel mileage (IS-F gets me 27 MPG Hwy & 12.4 @ 114 clip below was before lightweight exhaust & battery)

http://youtu.be/kxyZ0qrQolE?t=55s

Long-time BMW fan & hoping the new M3/4 runs mid-low 12s and 115-ish once they get early production irregularities/ringers sorted. If not the M3/4, then likely waiting for M2...

[phear_me]

Assuming some of these dynos that we're seeing are correct (410RWHP) my guess for an M4 with DCT using Launch Control - 11.94 @ 118MPH

I agree... in good conditions, this is a 11.9 to 12.1s car @ 116 to 119mph. I'm not personally really into drag times (I'm more concerned with road course ability) but I think the car is capable of those numbers stock.

[FogCityM3]

low 12 secs, 118-120 mph
