US magazine AutoWeek reviews the new BMW four-cylinder TwinPower N20 engine. Just last week, BMW confirmed that the new four-cylinder TwinPower engine will be powering an extensive range of 1 and 3 Series vehicles, but initially it will be available in the X1 xDrive28i model.

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).

Here is an excerpt from the AutoWeek’s review:

“More power, greater torque, reduced fuel consumption, lower tailpipe emissions and less weight–but better? Before driving the BMW X1 xDrive28i, the first model to feature the German carmaker’s new turbocharged 2.0-liter four-cylinder gasoline engine, we weren’t so sure.

The new engine, known as the N20 and set to lead a return of four-cylinder BMW models to North America for the first time since 1998, has been conceived to (indirectly) replace the company’s long-running naturally aspirated 3.0-liter inline six-cylinder. It’s part of an ongoing downsizing program at the center of BMW’s EfficientDynamics initiative.

First impressions reveal the N20 to be up to the job. With peak power arriving 1,600 rpm earlier and peak torque arriving 1,350 rpm earlier than with the six-cylinder, the N20 doesn’t have to be worked hard before delivering its best.

In everyday driving, the N20 is noticeably more responsive, although its sound is nowhere near as alluring as that of the engine it replaces. BMW says that will be fixed on certain models, including on an updated Z4 sDrive28i, with the addition of an electronic sound generator.”

    Good stuff. Saw this at Bimmerpost before too. Electronic sound generator sounds like an electric car thing though. Do not want!

    And what difference does it make ? Only that you know that the sound fake, the car is fast and powerful….

    There’s a typo in the link, you need two forward slashes after http:

    I hope they return back to the old model designations where the displacement matches that last two digits of the model number. I’m sure they are worried about going backwards with lower numbers but I think they should do it anyway. Next 3 Series should be a 320 and a 330. 520, 530, 545 etc.

    That’s simply embarrassing. Are we now ricers?

    F’KING FOOLS! Electric sound generators…. Do these people even realise how ridiculous that sounds. You put a small engine in the car and add some fake sounds to it so that it sounds like an expensicve car with a big engine!.

    THIS IS THE REASON WHY SO MANY PEOPLE ARE LEAVING BMW AND GOING TO AUDI.

    Just found out that the RS5 is actually a Lambo engine and now you compare that to what BMW is doing – small little 4 cylinder engnie WITH A FAKE SOUND GENEARATOR! – SIMPLY PATHETIC!

  • George

    Agree with the other posts. Electronic sound generation is a very poor decision. Who on earth wants to drive around in a BMW with fake sound? We’ll be the laughing stock of the car world. BMW, listen to your customers!

    BMW knows nothing Ii know better as I hide behind my computer screen bemoaning a real company that bothers to make something other than pathetic comments.
