Earlier today, BMW unveiled their new M model. The highly awaited and enthusiast-oriented 1M has finally taken its clothes off and revealed the body kit created by the M engineers.

The new 1M builds atop the 135i Coupe and it said to have the perfect balance. It is 71 inches (1803mm) wide – 4.8 inches (122mm) wider than its 1988 M3 ancestor – yet only 1.3 inches (33mm) longer at 172.4 inches (4379mm) long.

The new 1 Series M Coupe weighs in at 1,495kg DIN (3,296 lbs, preliminary), and features a 104.7-inch (2659mm) wheelbase, three inches longer than the 1988 M3. Front and rear track widths are exactly the same on the 1 Series M Coupe at 60.7 inches (1542mm) each. Compared to the 2011 BMW 135i Coupe, the 1 Series M Coupe is 0.2 inches (5mm) longer, 2.1 inches (53mm) wider, 0.5 inches (13mm) taller, and rides on the same 104.7 inch (2659mm) wheelbase.

Update: BMW 1 Series Catalogue

1 Series M Specs 655x451

It features a track 2.8 inches (71mm) wider up front and 1.8 inches (46mm) wider in the rear, and weighs 35kg DIN (77 lbs, preliminary) less.

The car comes fitted with an improved braking system. The internally-vented, cross-drilled cast iron discs measure 14.2 inches (360mm) in diameter at the front and 13.8 inches (350mm) in the rear. Featuring large compound disc brakes and electronic anti-lock, stopping power for the 1 Series M Coupe is strong, precise and consistent. Each disc is connected to a floating aluminum hub by cast-in stainless-steel pins. This configuration reduces the thermal loads on the discs, thus increasing their performance and service life. An electrically-driven pump provides the system’s vacuum power.

The 1 Series M Coupe is equipped with the M-specific, light-alloy cross-spoke wheels from the M3 Competition Package and limited-production M3 GTS. They measure 19 x 9 inches with 245/35/R19 low-profile tires at the front and 19 x 10 inches with 265/35/R19 tires at the rear, and are silver in color.

1M is powered by the N54 twin-turbo powerplant that was enhanced by the M division engineers. The turbocharger system developed for the engine of the new 1 Series M Coupe maintains a high output throughout the entire engine speed range.

Maximum output of 335 hp (250 kW) is delivered at 5,900 rpm. Nominal peak torque is 332 lb-ft (450 Nm) from 1,500 rpm to 4,500 rpm. Redline is 7,000 rpm. The enhanced engine management system of the 1 Series M Coupe includes an electronically-controlled overboost function to briefly increase torque under full load by another 37 lb-ft (50 Nm). This temporary torque peak of 369 lb-ft gives the car a substantial increase in acceleration.

The 1 Series M Coupe will complete the sprint from a standstill to 60 mph in just 4.7 seconds (0-100 kmh in 4.9 seconds). The standing quarter-mile mark comes up in 13.2 seconds. Top speed is limited electronically to 155 mph (250 kmh).

  1. Daniel Hoang says:

    This should be called a 135is rather than a “M” car. There better be major suspension upgrades to make up for the small power gain.

  2. Paul says:

    Thank you Daniel. I don’t this should be an M car, or come with the M price tag

  3. Babken says:

    Oh my God. When will BMW finally make an engine which has more power than AMG. What is this? A 335hp M car? It’s more than ridiculous. In 2010 M division produces a car that has just 335hp and they boast about it. It’s time to grow up, M engineers. And it’s time for BMW to wake up since nowadays the best performance engines are produced by AMG.

    • wazon8 says:

      What are you talking about? Do you really consider AMG as best engineers in the business? They still cannot reach the power-capacity ratio that M-division reached with their N/A engines from last M5 and recent M3. More importantly, sport cars are whole package, not only engines and it’s something that MB fanboys used to forget about.

      There is a simple reason why the power of this 1M is limited: Not to outperform M3 e92!!! Make the boost higher and you will get a car with singnificantly higher torgue than M3 offers plus close output to M3, plus suspension and RWD from M3, plus lighter weight. In other words, the car that would steal customers from M3. You would shot your foot, BMW is too smart to make such stupid move.

      • Babken says:

        Now AMG makes far more powerful and better engines than M division. It’s an established fact. As for this particular M model, it’s a bitter disappointment for me. If they were aiming to make 1M which should be worse than the almighty M3, they should have made it after the next generation M3 came out, but not now. Like I said having just 335hp is ridiculous nowadays, especially for an M car.

        • wazon8 says:

          Etablished fact? Show me 4.4 litre AMG engine generating 555hp or N/A AMG 5.0 litre engine that generates 507 hp or even AMG 3.0 litre generating 335hp. Man, data talk against you! What are on, disappointed fanboy who cannot understand that better performance amount to stealing customers from M3?

          • Daniel Hoang says:

            The 4.4 Liter is a twin turbo. Mercedes AMG does have the new 5.5 liter kompressor engine with about 525hp that is replacing the 6.2Liter engine. The new 5.5 AMG will be more efficient than the 4.4 X5/6M cars. The downside on BMW M engines is thet have lower torqe figures than their AMG counterparts. AMG cars will never reach 8-10k Revs like BMWs NA engine though.

        • Gram says:

          Better? Nothing better about throwing displacement in and engineering out. You just dont see Mercedes with high-revving engines making over 100hp/L without F/I

  4. Philippe Lam says:

    What’s with all the complaints about this car not deserving the M badge? Remember not too long ago, the E46 M3 came with about the same amount of horsepower but a lot less torque and no one ever complained about the E46 M3 not being a genuine M! Besides, M’s philosophy has never been about crazy horsepower and shoddy handling. The increased track widths and the addition of the M LSD should make 1 series M one sweet ride with more than enough power to satisfy 99% of the drivers out there.

    • Daniel Hoang says:

      On the contrary, bmw M cars were about handling. Also the e46 m3 came out 9 years ago and 333 hp was alot then especially from a 3.2 liter na engine. But this is 2011 , and 335 hp is less than sufficient for a m car. Even the infiniti g37 has similar figures.

      • Alex says:

        Yeah,well it’s a little bit more complicated. They can’t make the 1m faster than the M3. The difference in power between the 1M and M3, is roughly the same difference that was between the M3 and e60 M5, roughly 80 horses. If they would have given the 1m around 370 or 380 horses it would have been to close to the m3, and i think about as fast.

  5. Hugo Becker says:

    Just noticed something interesting. They grabbed the M3 brakes and big chunks of the M3 suspension for the 1M. But the track width of the 1M is 60.7″ whereas the track width for the M3 Coupe is slimmer at 60.5″. Not much but wider on the 1m. And the 1M’s track is over an inch wider than the 335is.

  6. Doug says:

    What effect does the torque “overboost” have, as experienced by the driver?

    I’m curious that they said that the *torque* is boosted but did not mention anything about horsepower. Is this a momentary boost, like porsche was doing, afaik?

    • Hugo Becker says:

      I think its additional torque at lower RPM – it’ll scoot away from a corner with a bit more alacrity probably – but it won’t be available at higher RPMs.

      If you add the torque at lower RPM you don’t impact the peak HP number.

      Horsepower = Torque * RPM/5252

  7. viper says:

    I think this car will lose against whatever audi rs or vw golf…..I truly belive that. because its a fat car with not so much hp

    • Daniel Hoang says:

      Compared to those cars, the 1 series is an agile RWD car. Take this car on the touge moutain roads of japan and that is where this car will exel. Its still not enough to justify the price.

      • viper says:

        that car with rwd on a snowy hill wherever in Jap or Austria will get its ass kicked by a quattro audi or a vw golf 4 motion rs and r32 models of course…Ive seen more agile cars than bmw and rwd…this is small power for an m car , a fat M car and an ugly one…its 2010..model 2011 and bmw has this to offer , this should be called 135is…they even use the same engine 3.0…..you could upgrade ur 135i better than this…you can stiff the suspension ur self , lower it put 19s on it squeeze the engine power (more than 340)…modify it ur self better than this….I tell you this car is nothing special , doesnt deserve the M badge

        • Daniel Hoang says:

          I beleive I aready said that this car doesnt deserve a M badge.

          I am talking on behalf of the 1 series and any RWD car. AWD wil dominate on snow and gravel, but on pavement and there is a sharp angle, An expericence driver in a RWD car can enter the corner at a high speed, and do a control drift around it and still have alot of speed. Other powertrains probolly cant do that or if so, not as well. You can have far more fun and enjoyment on a RWD than AWD and definatly FWD.

  8. Bimmer1 says:

    1. You can’t judge a car like this unless you drive it.

    2. I hope Dinan gets software out pronto for this so we can get the power we should have from the beginning from ///M. If I got 384hp/421tq from just a software update on my 135i, ///M should have at least gotten close to that!

    3. It looks awesome. Stop whining. You love it, you know you do.

    4. Viper, compairing a rwd M car to an AWD Audi in the snow isn’t really a fair thing to judge them on. But FYI, I drove a slammed M3 track car for two winters in western PA and that car went anywhere even with 4-6 inches of snow getting plowed out of the way by the front lip. Not that I could keep up in a race with a quattro car, but it went better than my 135i in the snow and the M3 had no traction control. Just snow tires, some extra weight in the trunk, and a real LSD.

    5. Let’s face it, we all want this car. And hell, my ’10 135i M sport stickered at $45,050. For the same price you get this. Well maybe a bit more with options, but there aren’t many to choose from.

  9. Laszlo says:

    how is it evolution ? In 1994 the E36 M3 in europe was released with the 321HP 3.2l Engine. Normally aspirated ! in 2011 the 1M makes 340HP from a 3.0l twin power turbocharged engine and we are supposed to be all over it ?
    less then 6% increase in HP and 6.6% less engine size so you could say the gain is a little over 12% compare to the original M3 engine. But for godsakes its with a twin turbo !!!! Slam a few mods on that 17y/o engine and easily get the 340HP. with no turbo, much less 2 turbo’s.

    This is a true M car then, the M as is Marketing 1 … its a shame… it should have been called 135iS and not 1M

    the 4.0l V8 in the M3 with the 414HP is also not a huge gain. The S54 engine made 343HP in europe and from 3.2L the 4.0l V8 makes 414HP that’s a 25% engine size increase and 20% HP increase.
    good thing the V8 is lighter otherwise we could call it devolution. The V8 engine is a gem, I love it but I think the S54 should have been reworked possibly bored to
    3.4l and variable cam and direct FI etc. could have increased the power to the 365HP range which would be still w/o turbo’s.
    I would prefer that engine in the 1M then this current one. I’m not a fan of turbo’s

    • wazon8 says:

      @Laszlo, do you really believe that there are weak achievements in engines’ engineering? The reason why I-6 in 1M has limited power is really simple: there is still M3 e92 and it shoudn’t be outperformed by cheaper car in M line up. But this deosn’t change the fact that this engine is able to achieve power output that you won’t get from any 3.0 litre N/A engine! We know right now that BMW is working on 450hp version of it. Isn’t it achievement over 17 years old engines to get 100hp extra, while reducing capacity and fuel consumption?

      As for M3 4.0 V8, you’re comparing apples to orange. It’s really different thing to reach high output from I-6 and from V8. Different engines constructions generate different difficulties enginers need to meet. It’s much more reasonable to compare this V8 with other V8 in BMW line up. Take a 5.0 V8 from M5 e39. It provieded 400hp, then you get M3 engine which is 20% smaller and is 5% more powerful. Then you see that achievement took place.

    • journalist_no_one_cares says:

      Laszlo, you need to get your facts straight before chat crap. In Europe, The September 1993 M3 was launched with a 286bhp 3.0L, straight 6 engine.

      It wasn’t until September 1996, when the M3 Evolution was realeased, that the 3.2L, 321 bhp unit came out.

      Second why are you comparing the 1M to the M3? If you’ve actually read the brief for why they’ve made this car, it’s because they wanted to make the M cars more easily accessible to the masses (they failed before they started for another reason, by limiting the production numbers, but lets not go there just yet).

      The point of the 1M was NEVER to be a replacement for the M3, so why would you think it would have more power than the current generation M3? In fact, BMW has purposefully tuned the 1M to 340 bhp, which is 3hp less than the previous generation e46 M3, yet the 1M’s fuel consumption is on average 30% better than the e46 M3.

      I’m not a fan of turbo’s either, but i’ve heard this engine up close and personal, last week, and I can say the sound is almost orgasmic. It feels like a naturally aspirated straight 6 with more torgue at the lower end. In fact, press the M button on the steering wheel and rev the engine in neutral and the sound rivals any overweight American V8 engine i’ve ever heard. It was music to my ears.

      This car is an evolution of the original concept of the M3 Sport Evolution of 1988, but in reality is a highly tuned e46 M3, that ticks all the boxes in the right place. BETTER FUEL ECONOMY than e46 M3. FASTER 0-60 TIME than e46 M3. 10 SECONDS FASTER AROUND THE NURBURGRING THAN e46 M3. Better handling/suspension than e46 M3. ENGINE SOUND BETTER THAN e46 M3.

      Considering the e46 M3 came out 10 years ago, and almost cost the same amount back then. This 1M is a bargain.

      I don’t do price comparison in $ to Euros…. especially for BMWs. BMW actually have 1 – 2 % net margins on 1 series and 3 series vehicles they sell to AMERICANS, it’s only on 5, 6 and 7 series vehicles they have net margins of between 5 – 8%. America is a loss leader/bargain basement seller for BMWs, since the Federal Reserve decided to trash the US dollar from 2002 onwards.

      That’s why despite the exchange rate, and State/local taxes it actually works out cheaper for a german consumer to FLY to america and have a vacation, then pick up his BMW M3 sedan/coupe from an american dealer, that was made in Germany, and have it shipped back to Germany and still save enough money left for a cruise. It’s crazy. All of the europeans are subsidising american sales of european cars. No wonder we’re on the bring of World Wide Depression.

      Any american who complains about the cost of a BMW should be shot on sight. tell them to go and visit BMW UK, or BMW DE and check what europeans are paying, even after subtracting the sales tax( VAT).

      • Journalist — yup Laszlo had his E36 M3 dates wrong. And based on what’s public info now, I think the 1 Series M sounds like a lot of car and pretty fairly priced.

        But please don’t ask Americans to be overly sympathetic to BMW. It could easily be argued its Americans who get the short end of deal.

        Less powerful models imported, new models released with bugs, parts that fail regularly (N54 fuel pump anyone), electronics quality absurdly low, “Free” maintenance that effectively means “No” maintenance now that BMW pays for it.

        So let’s not point fingers, and try to get along.

  10. Interesting comments. Putting aside the technological advancement argument, sound like most agree — this is a 135is, not a M car. Just like the 335is and the Z4is.

    M used to mean totally different engine and powertrain, not a tweaked N54 that is being put into one vehicle after another. Someone with a base 135 could probably do all the same things via the aftermarket.

    There really are some positive things here, like manual only. But BMW lost their nerve on this car. Maybe that is why BMW is only bringing 1,000 of them to NA — to ensure they sell out?

  11. BobK says:

    What car are we talking about here? The BMW 1 Series M Coupe or the BMW 1M??
    From what I understood they are two different cars!!! Or have I got the wrong end of the stick??

  12. BobK says:

    Follow up to above question.
    I understood as follows:-
    1. BMW 1 Series M Coupe is the current suped up version of the 135i Coupe.
    2. Bmw 1M was goimg to be a 1 Series Hatchback with the same motor, maybe tweeked a little more.

  13. Bob — No, the car being discussed here is the M version of the 1 series. BMW decided not to call it the M1 due to the famous, iconic M1 from the 1970s.

  14. BobK says:

    Chris, I appear not to have got my point across clearly.
    I know about the reasons for naming it the 1M instead of after the iconic M1.
    What I was wanting to know whether it would have the hatchback body, (probably the 3 door), or is it to be a 2 door Coupe as is the 1351 Coupe.

  15. Actually, it runs from 0 to 100km/h in 4.5s, and produces 340HP :)
