Roadshow has confirmed specs and also reporting some additional i4 specs:
• 530 hp from a 80-kilowatt-hour battery, producing about 390 kilowatts (approximately 530hp)
• 373 miles range (on European WLTP cycle); expect the US number to be a bit less, probably around 340-350 miles
• 0-62 in 4 seconds flat
• Electronically limited top speed of 120 mph
• 80% charge in about 35 minutes (on 150-kW DC fast charger)
• Adds 62 miles of range in about 6 minutes (compare to current i3, which takes 17 min to do the same)
• Generation 5 battery packs
• significantly smaller than the Generation 3 and 4 packs used in current BMW EVs
• easier to package in the vehicle's floor, and allows them to be more easily scaled for smaller or larger applications
• stronger, meaning they can better handle fast-charging situations
• battery module will weigh roughly 1,200 pounds, all of which will be packaged as low as possible in the vehicle's floor, directly between the front and rear axles
