Because the TwinPower Turbo engine and electric motor produce 308 hp combined. In addition, the electric motor alone can take you a rated 14 miles all electric. Basically that means on average it’s about 40 mpg across the board most daily trips. However, outside that range expect around 23 mpg.
However, in ECO PRO mode and with regenerative braking, using the 8 shifter STEPTRONIC pedals on the steering wheel and drifting techniques, the EV range was between 20-25 miles.
