The i4 is an efficient (~3.4 mi/kWh) electric sport sedan that, against a 28-mpg gas luxury sedan, cuts running cost per mile sharply — and electric torque comes without the premium-fuel bills of a gas performance car.
As a luxury car the premium is higher, so the running-cost savings are a bonus on top of the driving experience rather than the whole reason to buy.
What to keep in mind
- ~3.4 mi/kWh — efficient for a performance sedan.
- No premium-gasoline bills like a gas sport sedan.
- Luxury price means savings are a bonus, not the payback driver.
