In an interview for German Automotive Week, BMW confirms that the new four-cylinder TwinPower engine will be powering an extensive range of 1 and 3 Series vehicles. There is no secret anymore that BMW is looking to replace all six-cylinder naturally aspirated engines from their line-up and a new range of four-cylinder engines will be the replacement.

According to BMW, six-cylinder engine will continue to be featured in their vast line-up, a prestigious powerplant for the company. These engines will be equipped with direction injection and turbocharger.

The new N20 four-cylinder engines offers more torque and power, while having lower fuel consumption. The engine will be first used in the new X1 xDrive28i and produces 245 horsepower and 350 Nm of torque (258 lb of torque).

The engine can be matted to a 6-speed manual transmission or a 8-speed automatic transmission.
In the EU test cycle, the BMW X1 xDrive28i runs with 7.9 liters/100 km or 35.7 mpg imp (an improvement of 1.5 liters / 5.7 mpg), has CO2 emissions of 183 g/km (down by 38g).

Closely modelled on the BMW in-line six-cylinder engines, the all-new 2.0-litre engine with all-aluminium crankcase comes with BMW TwinPower Turbo technology features high-performance twin-scroll turbocharging system, High Precision Injection direct petrol injection with innovative solenoid injectors, and the latest further enhanced version of the BMW-patented VALVETRONIC variable valve control system.

A smaller engine, dubbed N13, will follow. The four-cylinder banger will be shared between BMW and MINI models and it has a capacity of 1.6 liters. The power range of the N13 and N20 will vary from 100 to 245 horsepower and the new 1 Series vehicles will make use of both powerplants. We anticipate an entry-level 3 Series from the new generation to be powered by one or more four-cylinder variants.

The North American market will receive the new N20 engine in the 2012 BMW X1 xDrive28i.

    Does it realy mean there will not be a naturally aspirated six-cylinder F30 3 series?

  2. bmwFan says:

    reminds me of the idiotic audi engine 4 cylinders, turbo, supposedly it is good on gas, in reality it is as thirsty as my 335 coupe

      Is 335i less economical than N/A V8 that provides similar output? I guess, the answer is “No”. Why then is this 2.0 litre supposed to be less economical than 35i? Because Audi’s is not? Well, BMW doesn’t buy engines from Audi, so efficiency of the last doesn’t matter.

  3. Laszlo says:

    it means no normally aspirated engine for BMW period.
    All other engines will be turbo as well.

    you might ask a question – more power more torque but what about reliability ?
    BMW’s answer – it will last a lifetime.

    In their little mind, a lifetime is about 7-8 years and 100-120k miles.
    sad and pathetic..

      Don’t joke. I already know people who made in 335i above 260.000km. My own has 180.000 km of milage and I don’t complain on its reliability. I remember the same story has been said when BMW launched their improved 3.0 litre diesel engine that was in 330 e46, for example. It was powerful, economical and so on, but people were afraid about its reliability. Mostly because drivers used to less powerful diesel engines and hence thought that it will be indeed unreliable. As it turned out this engine was really good at this point, the only problems I had with it was caused by quality of diesel that was sold at that time in my country. Then people started to suspect that new 35d will be unreliable. Again, contrary to those expectations, this engine was reliable too. I made in my own 335d around 270.000 and during this period this engine gave me no reason to distrust it.

      What all these stories show is that it’s rather pointless to predict durability of a recent engine basing on conditional knowlegde that takes as their premises sentences of the form “what would have happened, if one charched one of past engines this way”. The problem with it is that there are numbers of changes in materials from which engines are made and recent turbo charged engines are able to survive more than any turbo charched engine before them. If Renault is able to make 2.0 litre turbo charched engine that survives mechanically 300.000km with no bigger problems, then BMW is surely able to do even more.

      BTW, according to your previous posts my 335i should start dying, since it’s close to 120k miles, but contrary to that it’s still in really good shape as well as my friend’s above 150k miles 335i.

    The main reason I have bought 3 BMW’s in the last 12 yrs is the inline 6 and RWD.

    No naturally aspirated inline 6, then no more BMW for this kid!

  5. paavo says:

    …booooo…top power at 4000rpm! Is this really ultimate driving machine??

  6. yournextsource says:

    Not that this will be a surprise, but it will also be in the 528 eventually as well.

  7. Artmic says:

    I can’t wait to pay 50K for a new 3 series with a 4 cylinder engine… /sarcasm.

  8. Used Engines says:


    Its really great information guys that BMW confirms the new N20 four-cylinder engine will be used in 1 and 3 Series models, if it real so its so amazing guys.

    Thanks for information.

    FINALLY!! Now I might actually look at buying a BMW – I guess the success of the VW/Audi group from Wolfsburg got the big shots in Munich thinking smart again! In 2006, when I was in the market for a German made sedan – I loved the 3 series – but the lack of a 4 cylinder line turned me to my current VW Passat – the 2.0T FSI in this car gave me 200 BHP – standard and a true 25/32 MPG-better than advertised by VW – my reasoning was – why pay 10K more for a 3 Series for a pathetic 210 BHP and 22/25 MPG off of NA inline six (good engine still)? I saw the days of 5.00 a gallon coming then! If BMW plugs in the turbo 4 cylinder as planned in this line up, then I will be at the dealer signing the paper work for a new one! Saw some negative reaction to this – if BMW does things so well in the NA 6, then I am confident the 4 cylinder turbo will do well. Besides, it gets old leaving Bimmers in the dust on the highway with my VW 4 cylinder turbo – Munich needs to get with the program fast!
