vBox acceleration baseline numbers for stock i8
I haven't had this car very long. Have only driven it 100 miles. But I wanted to see what it was capable of in stock form so I went out and did some vBox runs. Conditions were 70 deg F and 90% humidity, sunny/hazy as fog just lifted. Slight downslope around -1.0 degrees. Car had a full tank of gas and battery was nearly fully charged.
I'm not the greatest driver on earth but I have done quite a bit of vBox testing on my other cars.
Here's the results of three runs. Two 1/4 mile passes and one 60-130mph pass.
First 1/4 mile brake boosting:
0-60 mph 4.466 seconds
1/8 mile 8.341 @ 88.867 mph
1/4 mile 12.741 @ 112.174 mph
Second 1/4 mile WOT off idle:
0-60 mph 4.680 seconds
1/8 mile 8.577 @ 88.851 mph
1/4 mile 12.977 @ 112.236 mph
60-130 pass: 12.928 seconds
Doesn't come close to the magazine times which may mean that a car with 100 miles needs further break-in, or that I need more seat time or both. Also could mean that BMW loads its press cars with a more powerful tune to get the stats of 0-60 in under 4 seconds and 1/4 mile in the 12.2 @ 116 range. I'm thinking a flash tune will be necessary to get these stats. For now I'm gonna drive it as is and see if it gets quicker with more time/miles. But I will likely flash tune it once more options/development has been done. Not sure I want to be a guinea pig on a new platform.
