N53 NA 3 liter in the new F30
Does anyone now when BMW will add valvetronic in the direct injected N53 na 3 liter. As we know they have done it to the N55 turbo. Also as a follow up, will this engine be added to the upcoming new 3 series. The excuse in the past was that our higher suplfur content fuel was the problem, we now know many others have direct injected cars in the US, they just cannot run in the lean burn stratified mode.

I'd be highly surprised if a NA I6 will even be offered on the F30. I hope there is but I'm not holding my breath. I4 TT ftl.

Better performace more power and torque Why would you not want this? Dont say something dumb like a 4cyl should not be in a 45k car because that makes no sense. You can blame the administration for this also not BMW.

I personally hate the sound of 4-cylinders, even turbo ones. Yes I know they have superior low end torque, but I'd rather have an engine that sounds nice and makes me want to rev it up to redline. Also I have yet to drive a I4 that is as smooth as an I6.
But yes this was caused by the stupid government regulations. I don't plan to buy an I4 until there are no more I6 or V6's available on the market in this car segment. |

Yes I know that. It sucks but BMW really can't do anything about it. NA engines are naturally less efficient. And they won't be able to survive with the future fuel economy restrictions. It's depressing to think about the future of cars. But I'll just wait and see what happens.

I am still dreaming about a fully hydraulic valve train in a cam-less engine. Now that would be something.

No its not. I thought this way too during the 70s with the gas issues then, and was worried there would no longer be fast cars like camaros and stuff, but sure enough, cars are faster than ever now.

I'd look at the new CAFE regulations as a challenge that BMW and other car manufacturers will have to meet. There were all kinds of back room discussions before the new standards were set and the car makers got some concessions in the form of eliminating the separate California regs. They never would have signed up for this if they didn't think they could meet them. And finally, they are "corporate average" regulations. Companies can still build Vipers, Corvettes, and M3s as long as they build enough other stuff to meet the average. I wouldn't sweat this too much. |
