Yes but you have to buy a car with a huge battery pack and crap performance (including the i8). I drive an M3, I'm not going to give up fast vehicles until self-driving cars are mandatory. Regenerative braking (with a small battery pack) could double the fuel efficiency I obtain. The existing regenerative braking systems available are horrible (in a number of ways) and not comparable to what's in existence for F1 and the 918. Regenerative braking for most cars now is where turbochargers were pre-1990s. The system I'm talking about can run only a few miles in full electric but gives a substantial boost in fuel economy because it's utilized for most acceleration below ~100 MPH.
