Similar-ish... the i8 is hybrid.
A nominal 36 mile ev range translates into a lifetime average 50mpg. It would be more but for the dearth of (working) charging points at destinations. Meanwhile, the car has immediate torque on tap, and can keep up with ostensibly far quicker machinery, if that's your mojo for the day. Or cruise comfortably for mile after mile. My record is 700 miles in a day.
& as I'm combining two cars into one, my i8 is for sale (as it the wonderful Aero)
