F80 M3 vs Model 3 P:
- 0-60 (3.9s vs 3.3s)
- Top Speed (167mph vs 155mph)
- Length (184.6" vs 185")

- Rear Track (63.1" vs 62.2")
- Weight (3,630 lbs vs 4,072 lbs)
- Roof (CF Roof vs Glass Roof)
- Software Update (less vs more)
- Torsional Rigidity (40,000 Nm/deg vs 19,000 Nm/deg) Note: this is for Model S, likely similar for Model 3
- Insurance Cost (lower vs higher) Note: in general, could vary depended on individual cases
- Range on full tank or full charge (300+ miles vs 310+ miles)
- Refuel or Recharge (minutes vs hours)
- Front Wheel/Tire (20 x 9.0" 265/30 vs 20 x 8.5" 235/35)
- Rear Wheel/Tire (20 x 10.0" 285/30 vs 20 x 8.5" 235/35)

G80 M3 vs Model 3 P: (Speculation on future improvement)
- 0-60 (sub 3.0s vs sub 3.0s)
- Top Speed (177+mph vs 164+mph) Note: improve by 6% on both
- Length (188.4" vs 185")
- Width (74.5" vs 73")

- Front Track (64.3" vs 62.2")
- Rear Track (64.12" vs 62.2")
- Weight (3,630 lbs vs 4,072 lbs)
- Range on full tank or full charge (330+ miles vs 330+ miles)
- Torsional Rigidity (50,000 Nm/deg vs 23,750 Nm/deg) Note: improve by 25% on both, for cross reference, 50,000 Nm/deg is in the range of Buggati Chiron)
- Front Wheel/Tire (20 x 9.5" 275/30 vs 20 x 8.5" 245/30) Note: Model 3 P may need wider fender
- Rear Wheel/Tire (20 x 10.0" 285/30 vs 20 x 9.5" 265/30) Note: Model 3 P may need wider fender

G80 dimension is derived from G20 based on F30/F80 scale. Refer to this post: https://g20.bimmerpost.com/forums/sh...&postcount=564

Would be interesting to know Model 3 P's brake system, disc dimension, number of pistons in calipers, etc. With either brake system, I'd go for extra virgin on the brake fluid!
Interesting comparison! couple of points:
1) We should compare interior dimensions too. F80 is tighter on the interior (legroom etc) whereas G20/80 should be closer to the P3. P3 has nearly as much interior room (97 cu ft) as the M5 (98.7 cu ft)

2) Weight for G80 in AWD form should be very close to the P3.

3) Drag coefficient - 0.22 for the 3. Do you have the same for F80?

4) It will be interesting to see if G80 gets sub 3 s 0-60. P3 is nearly there with people getting it ~3.1s.
