There are plenty of numbers between three and eight, so it shouldn't come as a surprise that BMW's recently unveiled i sub-brand will expand after the i3 and i8 go on sale in the next two to three years.

A few reports and our own sources indicate that the next two models will be the i4 and i5; a smaller coupe and a family focused four-door.

Both models will be based around the carbon fiber reinforced plastic "Life" structure to keep weight in check and use variations of the drivetrains fitted to the i3 and i8.

The i4 will supposedly be based on the i3's architecture, but will nix the extra set of doors and seats to become a two-seater with a sloping roof, wider track and a more sporting demeanor. Power will likely come from a variant of the i3's electric motor, with the same optional range-extending engine mounted out back. BMW wants to have at least one affordable i-branded two-door within the next five to six years, and considering the i8 will likely crest $100,000, the i4 will be a more attainable entry point for the marque.

Less is known about the i5 aside from the fact that it will be a more conventional four-door sedan with a coupe-ish profile and power provided by the same plug-in hybrid drivetrain as the i8. That could mean up to 400 lb-ft of torque when the turbo'd 1.5-liter and electric motor work in unison, creating one incredibly compelling hybrid sports sedan.

However, both models are a ways off. Concept versions should arrive sometime after the i8's launch in 2014, so don't expect either to arrive until late into the decade.

      I honestly don't mind a selection of enviromentally friendly BMW's, as long as they stay true to the BMW name.... drving dynamics and RWD. If the i3's price is reasonable, I might be a potential customer in years time. An eco-friendly RWD hatch with BMW dynamics, now that's what I call a perfect car.

      I'm waiting till all the concepts and hype settles down and I see actual production cars before I even begin to comprehend what BMW is producing in the next 2-3 years. I'm still a big fan of the BMW Vision EfficientDynamics concept and the i3 looks sharp and futuristic, but with all of the big changes BMW doing with hybrid power-plants and FWD models, it's been crazy keeping up with it all. Who do they think they are? Nissan? (read Power 88)

        Amen to that. These concepts (prototypes?) are way too Tron for the street. However, I'm open to new designs, shapes, and drivetrains, as long as they're done right. Also, some of these will probably look better in person than in pictures, so it'll be an eye-of-the-beholder kind of decision.

      Even though the names suck something else, these are BMWs most interesting models and they aren't even for sale. Longing for the day of a powerful all electric M3, but of course with a real name.

        I like the names, especially the ones with an M before a number. While BMW has useless alphanumeric crap like X6 xDrive 50i, it always helps to distinguish between the many model variants. They cant all have evocative names, otherwise going to a BMW dealership (or Audi or MB...) would be like going to an exotic zoo. "Hi Id like a BMW Tiger Lily Edition Curried Rice". These i models do look very nice and futuristic, even if I disagree with the powertrain choices. I doubt you will see an electric M3, because the M division is very traditional and performance oriented, or at least until 4x4's and turbos came on the menu. Maybe an i5 M sport edition, since the i series is electric or hybrid? Terrible name though.

        The Scion xB has the same drag coefficient as the Tesla Roadster.

          No aerodynamic consideration? It's a fking sports car you deadbolt.

        BMW's are actually pretty aerodynamic despite upright proportions and a flattish front. Funny that on an article about a normal car, you complain it isnt electric. Now on an article about even an electric car, you still have issues that you pull out of your ass. Stop your continuous and dreary trolling please.

      Seeing more i models would be interesting. i8 looks top notch and i4 counterpart would be neat. Though I wonder what is BMW's definition of "affordable"...

      BMW-affordable, performance-family, not exactly words that go together. Trying to be all things to all people is usually a recipe for disappointment.

        I got downgraded in the earlier post about the global luxury sales numbers of the big 3, because I said that BMW will somehow in the future find itself competing with Toyota ...... I guess i spoke too soon. Nevertheless I look forward to seeing how they implement the "carbon reinforced plastics," that could be innovative and a game changer if they can meet all safety regulations.
