I find it hard to believe that the X5 will have a 4 cyl engine.

Right.
I'll remember that the next time I see an Ultimate Drive Machine commercial. You can't blame Audi for whatever they make. They only brag about "Truth in Engineering". It might be the slowest little pipsqueak car in the world, but it's truthfully engineered with no pretense about being the "Ultimate".

I think this is good news. Obviously BMW is expanding it's competition in the market, needless to mention the 2 other brands they are after, Audi & MB...
On the other hand, I believe this will play good on the co2 emission, with an additional power compare to today's 320 4 cylinders and turtle like acceleration ??!!! |

I like the change as long as they don't touch the 35i and add 2 more engines to the Z fleet. a 4 cylinders turbo engine is gonna be more powerful than the 6 being used in the 23i, that's for sure ,and the 7 speeds DCT is gonna make it into the 28i which is good news.
I think I'm gonna press the pause button on my order and wait a month or 2

Exactly. I don't know why some of you are bashing the new engine. With a tune, this will smoke the na 6 any day of the week.

The big question that remains is the timing of all of this. Which model will be the first to get the new turbo 4? F20 1 series? Z4? X1? F30 3 series? X3? Or will it be intro'd in many models at the same time? And for that matter what will be the last naturally aspirated BMW to roll off the assembly line, and when? My guess is that the last one will be either a 528i or M3, at least for US consumption. I kind of hope it is an M3 - it would be particularly symbolic and a fitting (though saddening) end to the era of the naturally aspirated BMW. |

I'm growing tired of the better efficiency claim of turbo engines. Real world numbers are not showing this to be the case. The NA I-6 from BMW gets over 30MPG highway in many models, no worse than Audi's 2.0T. Ford's SHO with V8 power and V6 efficicnecy is getting 16-17mpg in long term tests. All the while the turbo engines are produced at a higher initial cost and a higher replacement costs to the owner. Plus BMW hasn't proved that they can reliably build a turbo yet. I think turbos are being forced into the market with the hybrids and other "green" models. I'm all for more efficient and powerful engines but I'd like the numbers to actually reflect the claims.

For example, my old 135 with the JB3 was much faster in a straight line than my dad's 07 M Coupe....but it could not hold a candle to the way the ///M felt, sounded, handled, etc...and the engine in the ///M is NA.... The 23i engine has been configured for more or less BHP, depending on what BMW has wanted to accomplish...if I recall correctly, it is capable of more grunt.... Just something to think about...

There's a reason I'm driving a BMW and not a VW or Audi. However, and as much as I am addicted to BMW's I-6 engines, my car would be oh so sweet with VW's 2.0T under the hood and an aftermarket ECU tune!! |

Its not all about speed. A 4cyl will never be as smooth or sound as good as a 6cyl.

235 hp out of a turbo 4 banger sounds OK to me, remember VW only gets 200 hp out of their motor. The rating is better than the NA 6, and the engine will likely weigh a lot less. In the smaller cars, where there will probably be only 3 and 4 pot motors the engine bay can be 8 or 10 inches shorter allowing more interior space in a car of the same size. In these models additional weight savings are possible as the engine mounts and associated platform elements do not have to be as heavy as they would have been with an I6.
Bottom line is we are going to have to wait and see how these cars drive. I hope these new EPA fuel economy standards are not going to be like 1968 when pollution controls appeared in the US. Horsepower and fuel economy numbers fell like a rock overnight and did not recover for a long time. Who wants to take the bus just so the Maldives does not go under water?

But the N54 with double turbo easily can be remapped too to add another 60HP and 100Nm torque. So why people say the engine can't be tuned properly?

A 4 cyl turbo it s much efficient than a 6 cyl aspirated. I'll give u an example: in Europe VW & Audi sale much more cars with petrol engines (TSI/TFSI) than BMW. Here, the averrage people don t need cars with more than 200 hp, so 4 cyl and around 175 hp are enough for some good performances and also a good fuel economy. Also the taxes are much better (lower) for this kind of engines!
I'm sure that these kind of engines don t present so much interest to the North American market, but for Europe this will be a good move for BMW |

well, I drove a Mini Cooper S with 181 hp two weeks ago and thought it was dreadfully slow - I guess I am use to my wife's Z4 hotrod; however, I had a Saab 9-5 with a 235 hp 4 and it was strong. I do know that the inline 6 NA is my favorite BMW motor of all time and it will be a huge brand mistake to ditch that motor in the lineup as a whole
