I've owned a Toyota Prius for almost ten years: Zero failures; no repairs. At 140,000 miles, I'm still on original brake pads. The air conditioning is all-electric, there is no alternator, and, in fact, there isn't a single belt in the engine. Consider two amazing performance benefits you could realize: First, the electric motor delivers instant torque. Tesla has proven that this is a fantastic performance benefit. Second, in a turbocharged engine, heated intake air is a performance limitation. BMW has experimented with water injection to solve this... but what if the electric air conditioning system passed through the intercooler? Now you have well-cooled charged air passing into the air intake, maximizing boost without removing any horsepower. And of course the air conditioner itself would take up none of your car's horsepower. I'm absolutely certain that well-engineered hybrid and all-electric systems are mechanically superior and offer higher performance and reliability than all-mechanical systems. This has been proven since the introduction of electronic ignition and fuel injection, and now with hybrid technology. |

Potentially you could make the battery a bit smaller but I think it would still be quite a bit of extra weight. The only way to get around this would be to change to a 4 cylinder engine for the M3/M4 or down to a 6 cylinder from a V8 in the M5/M8.

First off, I personally am a fan of hybrid sports cars.
If you've ever watched LMP1 blow out an LMP2 or GT car in WEC you'll be a believer. The instant torque on the front wheels kicks in as you exit and you convert to the ICE power as you head down the straight. It's an excellent system. A few flaws though. They cost a bunch and are very complicated. Despite costing millions and millions more than an INDYCAR they are still a few seconds slower at a track like CotA. Granted this isn't a great comparison, but it shows that the hybrid tech isn't really an improvement for light weight V6 with a turbo. Batteries work by either putting out a little energy slow or a lot of energy fast. The i3 is slow and slow. It charges slow and dumps it's battery slow. An LMP1 charges batteries fast, dumps it's battery super fast as well for big power boost. It can only do 1 lap on hybrid power alone. BMW already tried to release a hybrid sports car. You remember it? Nope. Active hybrid 3 and 5. Could do 3 miles on a charge but it also had 390 HP and weighed 3600 lbs. that's damn close to an M3 in power to weight. Well the auto press hated it and it died. Nobody understands performance hybrid car tech and do they just wanted to know why it couldn't go 30 miles like a Toyota and why it had a big engine and poor mileage. Normal people think hybrids need good gas and electric range. Activehybrid died and what replaced it? 330e. 180hp 4 cylinder with a massive battery and a 80 ho electric motor. It weighs in at 3800 lbs and has a range of 30miles. I think an article was just posted this week praising it. The other hybrid car BMW releases was the i8, which has a proper set up IMO. Electric front and ice rear. Proper transition from electric to IcE for performance as you increase the revs. It has a 30 mile range battery set up though. Basically everyone who tracked it ran out of juice about 10 mins into a 20 min session. You simply can't have proper electric performance for sport AND range. Batteries don't work that way. You want long range you'll not be able to recover that range fast enough to have hybrid performance for 20 mins, let alone a proper race like an 'M car' is supposed to be. If BMW releases an iM8 with a proper ICE and a proper battery system I will buy my first new BMW ever. Even better would be an i8 carbon fiber chassis with the Motorrad HP4 race 200 hp engine in the rear and a equally powerful émotor and battery in the front. High rev, 50 mpg, 400 hp, ultra light weight and an electric motor to fill the gap. I think we will see electric turbos first as that's an easy way to be good boys PR wise, get a nice turbo, and promote the i brand. As for a proper hybrid M3? I'm very skeptical. The new 3 series is already as big as an e60 and Will weigh in at 3700 lbs. you stack a 30 mile range battery and motor on top of that and you'll get 80 more HP and 400 extra lbs. yikes. If BMW went for a proper torque dump battery the press would rage about the lack of range in a $70k hybrid. The tech is far too New for the pop culture perception of it to allow for a good car. I mean, I'm probably one of 2 people in this thread who even knows what an LMP1 is. On top of that you have design and maintain a KERS system for 100k miles and warranty is for 50k of those , that will be expensive, let alone 300k miles. BMW has no choice but to hybridized because of German politics. I also don't think they can make a true M3 hybrid with a proper Racing hybrid system for under $100k. And keep in mind M cars should last 150k miles or more. You're pressing your luck. I'd rather see M chase weight loss and electric turbos and let the i division Pursue an M3 rival that's hybrid. What I have a feeling we will get is a G20 M3 with a 330e battery in the trunk and an electric motor taped to the front of the ZF8. Big yikes. And I hope nobody is dumb enough to buy it. No performance gain, just e range, to make the Bundestag feel good about themselves. I also hope BMW i keeps the carbon fiber stuff, but I get the feeling they will just start making 4K lb 3 series with a battery and some touch screens inside. BMW is looking for a hybrid racing series so I'm pretty confident they will try to do this. It will be sacrelige if the M brand is tarnished even more with that lazy engineering we see in the 330e. |

So have clutch-less transmissions; yet we still see plenty of people retract at the thought of a DCT-only M2/M3/M4.

BMW i has been very disappointing. Everyone thought by BMW being one of the fitst major automakers to develop electric cars for the mass market, they'd be ahead of the pack with great tech. But that hasn't been the case.
And now the BMW i boss seems like he's just regurgitating the same crap that BMW has said ever since BMW i was established. Everyone knows that electric motors give immediate torque and that is one of their advantages over combustion engines. How about you tell us something exciting or innovative that shows you will be able to compete with the likes of current Teslas and future Porsches and Audis? Very uninteresting and un-BMW-like.

IMO what the M division should get is a boss who stays there the next 20 years, like Porsche has with Preuninger for the GT cars. Someone with enough passion for performance and for the brand who fights to get his vision realized.
People respond this type of stuff because if done right, it permeates through to the car’s character - and in a world of democratized power/performance, that’s the only thing left to sell really.

Although there's all sorts of hype about electric vehicles, true electric-only cars are a miniscule amount of car sales at the moment. So personally, I don't see an all-electric M car---or at least many of them---for at least a decade, if not more.
But I do think there could be some value in a hybrid-based M car. My biggest concern with the hybrid approach is the removal of the manual transmission. Not that it's impossible to have a manual in a car with a hybrid drivetrain, they do exist, just in very small numbers. It would be amazing, IMO, to have something the size of the old Z4 coupe, with a manual transmission, and an updated version of the S65 engine with direct injection and a hybrid drivetrain. What a beast that would be! The future doesn't have to be terrible, IMO. It really comes down to the will of the company. And if BMW's attempt at, say, a hybrid M3/4 is a miss, well, there's always older cars. There's also other brands. |

Unfortunately what the press release is really saying is "please don't forsake BMW as a brand because we are so far behind in thinking about doing any performance oriented electric technology vehicles ". I'd love an electric M5 but I'm going to be considerably older before they get anywhere at this rate.

F1 technology in small coupes with 1300kg-1400kg curb weight would be epic.
And get rid of that AWD joke in M cars please. Smooth torque curve and good tires are more than enough vs. 100kg drivetrain weight penalty.

I see M variants of i cars, like i8M or i5M, but an electric or even hybrid M3 or M5 sounds awful. I hope bmw wont do it (so basically I hope audi wont do it and then bmw copy them)
