Wheels and tires not withstanding, don't discount that driver assistance plus will add a little weight. Remember, there will be two(2) radar antennas under the sides of the rear bumper cover and the requisite wiring. The oscillators are likely flat and angled rearward as in other blind spot/cross path systems operating in the 24 ghz range. They will drive your radar detector wild on K band. Specifically why I told my sales rep I was not looking for that option on the CP M3 that will be replacing my M4 in a couple of days. Incidentally, I half heartedly cross shopped the Camaro ZL1 and interestingly, that car comes standard with a blind spot/cross path radar system, which can not be deleted when you spec the car. Oh, and with these systems even when you "turn them off," the oscillators are still energized and transmitting. Want to know for sure? Just bring a radar detector to the dealership and fire up the car BEEP, BEEP, BEEP!

I remember when Rolls-Royces were the only cars weighing 3600+ lbs.
Fitting that BMW owns Rolls-Royce now.

Instead your car as weighed came in 162 pounds heavier than mine and we both had the same fuel load (about 2 gallons in tank). Very unclear why your m4 would weigh so much more than mine, unless the DCT weight difference is alot more than advertised.

I'm pretty sure the competition package is faster in a straight line. I've seen the M5 vs M5 competition package and the competition package easily pulls away. I would imagine with the additional power it will more than make up for the weight difference in the M4 as well. BMW tests the MCP against the benchmark standard M4 I'm pretty sure and there's probably a youtube video showing the difference like the M5 vid I saw. Speaking of witch, there should be a vid showing the difference between 340i and 340i MPPSK in a drag race to demonstrate the difference as well.

When we weigh cargo aircraft, we actually weigh the plane three times by placing calibrated scales on top of the jacks. In between weighing the aircraft is down jacked, scales are zeroed and then up jacked and weighed again. It is the average of the three weights we use because each time it is different. Same aircraft, different weights. Your 66lb difference might turn into something less given calibration, average weight, yatta yatta.

E92 M3 had a special motor and was a balanced package. This F80 has been a disaster since inception. Can't fit a square peg in a round hole. Look forward to the next edition it's all you can do.

I thought these cars were in the 3500 lb range. Was looking to get it to 3200-3000, but might be a bit of a stretch without getting drastic.
Only option is ZCP? |

My f80 4-door weighed 3,450 pounds with 2 gallons of gas in the tank. That's about ~200-300 pounds less than an e90 m3 by comparison. I don't know why my f80 weighed so much less than the Ops car. By all accounts, his car should only weigh slightly more than my f80 given the equipment and it's an f82.

It sounds like you've been reading too many blogs. The competition may have caught up in recent years, but that doesn't mean the F80 isn't an exceptional piece of engineering.

It is indeed special in its ability to throw rods through the block due to bearing failure.

My scales are calibrated every year. I live in MN where intercomp is HQed. I wouldnt call the readings unexpected. I had no expectations goin in. I just wanted to make sure the fuel load was nearly the same. Only way to really do that is to top off both tanks. In this case i drove the white car about 40 miles (mostly city) after filling and based on avg mpg that puts it down roughly 2 gal. So i subtracted roughly 2 gal from the 9.7 it took to top off the blue car at the dealer. Certainly my method would put the calculated weight with same fuel load within 5 lbs. I have lots of practice calculating fuel burn rate, fuel loads, etc. Running a car in SCCA and NASA the weight that matters is the weight that the car comes off the track with driver. So you are constatly playing with fuel load to get the car with in 5lbs-10lbs of min when it rolls onto the scales after a race. Last edited by Rocklobster; 03-25-2017 at 11:10 AM.. |
