M-Power.com just released the first out of three articles about the technical details on the 1-series M Coupe. Here are the highlights at a glance:

"the starting performance of the M TwinPower turbo engine was given an extremely spontaneous twist by redeveloping the mapping of the software. This is also helped by the approximately two kilogram lighter flywheel."

"Newly designed piston rings are used in the engine. The two turbo chargers use turbines made from high tensile steel and will easily withstand temperatures of up to 1000 degrees Celsius."

"The compact six-speed transmission with dry sump lubrication is a new development and has a weight of just 43 kg – much lighter than similar gearboxes."

"Because the drive shaft is also a new part, every ing is specifically tailored to the requirements of the BMW Series 1 M Coupé in this combination, starting from the flange of the crank shaft."

"The same also applies to the front-end, which is characterised by large cold air inlets. These ensure that plenty of cold air reaches the powerful in-line six-cylinder engine. Together with additional cooling components, this arrangement ensures the technology is kept at just the right temperature during competition."

"In order to optimise the aerodynamic properties, so-called air curtains are used for the first time in a series-built car."

A maximum of 500 Nm torque and 340 HP may impress in numeric terms alone. Likewise, average consumption rates according to the ECE standard and 9.6 litres per 100 kilometres, as well as a crisp acceleration to 100 km/h in 4.9 seconds are all welcome statistics. But what about that genuine M feeling? What do the emotions have to say?



The community test drivers in Leipzig were very impressed with the drive. This is something that might surprise outsiders, however the reasons are clear:



The BMW M hallmark is evident in numerous details: thus, the starting performance of the M TwinPower turbo engine was given an extremely spontaneous twist by redeveloping the mapping of the software. This is also helped by the approximately two kilogram lighter flywheel, which was also optimised for the maximum torque of 500 Nm. The M button on the wheel enables vehicle response to be further enhanced. With real fire in his eyes one of the community test drivers in Leipzig described this effect:

The precise steering responsiveness typical of M automobiles is assured in the BMW Series 1 M Coupé by the Servotronic speed-dependent hydraulic steering support – this guarantees perfect control and predictability thanks to a constantly exact feeling for the steering angle and precise response in relation to the state of the road. This enables the BMW Series 1 M Coupé to be steered with ultimate precision, something that is sure to being a radiant smile to every drivers’ face.



The characteristically powerful acceleration from even low revolution speeds, paired with an impressive rev performance and long-lasting thrust are enormously attractive and play a vital role in the exhilarating experience on the race track.



A button on the instrument panel enables the driver to activate the M Dynamic Mode (MDM): extended intervention thresholds for controlling driving stability and specifically applied over-steering take driving dynamism to the next level. Naturally, the DSC can also be fully deactivated, however it is advisable never to underestimate the spontaneous power of the BMW 1 Series M Coupé.



Newly designed piston rings are used in the engine. The two turbo chargers use turbines made from high tensile steel and will easily withstand temperatures of up to 1000 degrees Celsius.

The direct fuel injection contributes significantly to the high degree of efficiency of the engine, which uses Piezo injectors arranged centrally between the valves to ensure a particularly precisely dosed fuel supply.

The high degree of compression also increases the effectiveness. In addition, measures such as brake energy recycling and demand-controlled ancillary units are also used, so that the M engine of the BMW Series 1 M Coupé unites fascinating performance with great efficiency. This is something that will also be important for drivers with a sporting interest - after all fewer pit stops never did anyone any harm.




The compact six-speed transmission with dry sump lubrication is a new development. Its suitability for high torques is combined with a weight of just 43 kg – much lighter than similar gearboxes. The short M gear lever underlines the crisp and precise gear change – the traditional sportiness of this elite class.



Because the drive shaft is also a new part, every ing is specifically tailored to the requirements of the BMW Series 1 M Coupé in this combination, starting from the flange of the crank shaft.


The same also applies to the front-end, which is characterised by large cold air inlets. These ensure that plenty of cold air reaches the powerful in-line six-cylinder engine. Together with additional cooling components, this arrangement ensures the technology is kept at just the right temperature during competition.

In order to optimise the aerodynamic properties, so-called air curtains are used for the first time in a series-built car.



Special air inlets give rise to the "air-curtain".



There is little doubt that the driver’s hearing adds to the emotion of the M Coupé: the two twin tailpipes of the exhaust system, the driving experience with a tailor-made, compact, minimalist sound, which is as lively as it is captivating.



However, this BMW M is also absolutely perfect for day-to-day use: “This is all the more important because we expect that many BMW Series 1 M Coupés will be chosen as first cars,” explains developer Jürgen Schwenker.



Are features such as a genuine four-seat configuration or a 60:40 folding rear seat important? Indeed they are, because these advantages ensure that the BMW Series 1 M Coupé can be used on the street, while other cars are forced to wait in the garage for their next opportunity to be used.

It would also be a pity to miss a single minute of the pure driving pleasure the M has to offer.

Haha can't believe that. Not half an hour ago did I log in to M-Power.com and I missed it!

Thanks for posting South, great read.

Thanks for posting South. A lot of good info.

"The compact six-speed transmission with dry sump lubrication is a new development and has a weight of just 43 kg – much lighter than similar gearboxes."



It looks like it doesn't have the same transmission as the 135i afterall

Every bit I read about the car makes me more and more of a 1'M'Addict!

This was expected but loving the light weight flywheel too!!

Wow.

Looking forward to pt. 2.

"Newly designed piston rings are used in the engine. The two turbo chargers use turbines made from high tensile steel and will easily withstand temperatures of up to 1000 degrees Celsius."

I highly suspect this is NOT unique for the 1M, since many info reveal that the Z4 35is has the same engine. For example, this article mentions that the Z4 35is turbo can also service 'up to 1000 degrees Celsius and can operate at temperatures above' (it's a Hungarian website, but you can use Google translate to read it):

Another point, since the N54 (340hp version) and N55 are BMW's latest turbo engines, therefore they are new designs, of course they also have newly designed piston rings. Therefore I guess there is nothing new about 1M's engine.

Also for the 6sp MT: even though I can not remember the source, I recall for 2011 model, the 6MT in 135i was changed to a dry sump lubrication type, so I am also very curious whether BMW can officially clarify that the 6MT in 1M is 100% new and shares zero common parts with the 6MT in 2011 135i.

Thanks for the post. I love thata color.

[1M Fan]

This is an interesting read. The transmission sounds unique. If other models had it, the magazines would have mentioned it. I'm curious about the rings, perhaps zero gap?

[pyrat]

enjoying reading more about the 1M. The color is

[Diver]

It has to be a great car, but I get the feeling there will not be that many of them. None the less, there is a huge amount of promotion going on. Perhaps this is a hint at the future M3.

[Sephiroth]

Interesting. Anyone know of another application that uses a dry sump equipped transmission? Sounds like they did it for weight reasons but how did they avoid exorbitant cost?

[providence]

nice read... now release the option pricing so we can get-on with the official ordering!!

[Yogijet]

Nice. Looking forward to installment number 2!

[marsel]

I have a 2011 model and would love to know if my car's 6MT was changed to a dry sump lubrication type. That would be greatly appreciated!

damn, i should of paid more attention before i posted the same thing.

So does this confirm brake regeneration?

Im Impressed at this point..BUT I cant say anything till I test drive one.

[keanu1]

with 500 Nm it has to have more than 340 hp!! this car has more tork than m3!!! i can imagine the potential, but ..let's wait and see how it compares to ttrs

Good read. Nice start to another sleep deprived, coffee ignited day.

The new lightweight 6MT might be the reason no DCT is offered on the 1M.

Indeed! Otherwise the total weight would never had been under 1500kg empty. I can't wait until May, i am so exited to collect mine
