So thinking you are going to get a 340i size car with 0-60 times of 4 seconds while achieving 55 MPG using the i8 drivetrain architecture, it's not going to happen. To get more room in the car the i8 drivetrain needs to be reconfigured and reduced in size, which means reduced performance and power to achieve the MPG targets. We already have cars that the dual-type hybrid drivetrain has been shrunk and de-powered to increase MPG and add passenger/luggage space. These cars are the Volt, the plug in Prius, the Camry/Accord/Fusion hybrids etc. Where the dual-type (electric and ICE) drivetrain has been repackaged, shrunk, and fitted all under the hood so the vehicle has useable 4/5 passenger space and real luggage capacity.

However - the current i8 architecture and technology will be fairly outdated in the not-to-distant future - so with future hybrid tech - this all will fit into a sub-3500 lb family sedan priced roughly equivalent to the current M3/M4 (adjusting for inflation). Just a question of time... |

A turbocharger is already a type of supercharger, so indeed adding electric assist doesn't change this.
https://en.m.wikipedia.org/wiki/Supercharger Along the lines of the naming convention used in the above article, perhaps you'd prefer to name it electro-turbo-supercharger, or maybe just eturbocharger for short. I believe it's pretty much confirmed that the next M5 will continue to use the S63 while adding optional AWD (standard feature in the US). See the November 2015 update near the end of this post: http://f80.bimmerpost.com/forums/sho...d.php?t=901686 Of course that doesn't necessarily completely rule out hybrid assist, but it seems unlikely at this point. |

So perhaps the very first Power eDrive M model will fall under the M performance brand. Clearly an M550e will use an I6 just as the M550d does. This could, in short order, push the 550i out of the lineup, leaving the V8 (which can also be paired to eDrive in a future generation) just for the proper M car.

Dirk Hacker is really overthinking this. I don't think they need to look to electrification, they essentially have hybrid M cars already as they burn both gas and rubber.

If it'll be anything like Porsche 918, La Ferrari, P1, it should be quite ok.

It may work...or it could be a complete fucking mess. Have you seen how difficult it is to open the hood in an i8?

Here's the answer:
AWD 3L and 4L 6 Cyl turbo engines with electric assist built into the engines powering the rear wheels through a DCT transmission combined with 2 electric motors powering the front with 28kW capacity. Total HP deployed in the 3L combination, up to 550. Total HP deployed in the 4L combination, 650+. I'll definitely buy a next gen ///M equipped like this. |

That's where the hybrid technology is right now. Give it 10 years. You'll be carrying a backup battery for your 4 sec 55mpg 340i sedan in your back pocket. |

Huh, really? It's been a while since I checked, but from what I recall it wasn't too bad, but there was a slight noticable delay when swithcing between power sources.

It is unlikely at this point that BMW will invest in a new six cylinder engine family with greater than 3L displacement. So, if there is going to be a 4L engine, it will almost certainly be a V8 (like Mercedes and Audi have).
Also BMW has stated in the past that they are targeting up to 200hp/L for their turbocharged engines. In fact, there was a dual motor + I4 eDrive concept from over a year ago that made a reported 670hp: http://www.autoexpress.co.uk/bmw/895...em-gets-670bhp If we eventually see something like this combined with the aforementioned I6, over 1000hp is theorectically possible in future evolutions of the technology. Naturally, this puts the long term need for the V8 in peril. It is a not a question of if, but of how rapidly this will play out. Quote:
