There isn't a full list of specs out on the i4 yet but here's what I've been able to find so far:
Power: 530 hp
Battery: 80 kWh (It will use BMW's Generation 5 battery packs, which are smaller than the Generation 3 and 4 packs used in their current EVs).
Range: BMW claims 372 miles
0-62 mph: 4 seconds
Charging: 150-kilowatt and up to 80-percent of the car's driving range in 35 minutes
What kinds of specs are people expecting the i4 to have?
