F30 328i Important Questions
Hey!
I have been planning a 3-series from quite a while and finally the time is nearing. I'm strongly considering two variants that is the 320d SportLine and the 328i SportLine. Both are top of the line variants and the 320d SportLine costs around $69,000 with the Power Performance Kit and the 328i costs $75,000 on the road. The equipment level in both the cars are more or les exactly the same. The fuel scene here in India is opposite as compared to the United States. The Petrol costs higher than the diesel and the availability of good quality Petrol is rare. Usually it's 89 RON Petrol all over. Here are my questions; - How would the 320d with the Power Performance Kit and Performance Exhaust perform against the stock 328i running on 89 RON petrol? - The claimed figure of the 328i to 100 by the company is 6.1 secs which is tested on 98 RON Petrol. By how much will it deteriorate if 89 RON Petrol is used? - Can the 328i go into limp mode with regular use of 89 RON fuel ? Thanks in advance. |

89 RON? I would never run gasoline in the 328i engine with such a low octane rating. You're talking a turbo engine with relatively high compression. The only way 89 RON would work is if you kept the revs super-low. At that point, you might as well have a diesel. The U.S. owners manual says minimum 89 AKI which is like 93-94 RON. 89 RON is about 84-85 AKI which we can't even get in the U.S. Well, not in California anyway.

Well if you compare the On-highway diesel prices in some states it is more than gasoline, for e.g. take Cali. The diesel is slightly expensive. Also, the 'scene' I was referring to was the availability of diesel in the US which is not as good as gasoline there. |

I would not run lower quality petrol in my 328i so if I lived in an area where diesel is more abundant I would get the 328d. The issue is the long term effects of running poor quality\lower octane fuel in your 328i. You will have some issues in the long term.The diesel version is just as fast as the petrol and if you need more performance then there is the after-market tunes that you can buy. I think you said you would be getting the PPK so that would make the 328d a nice performing car from the get-go. Good luck on making your decision and Congrats !

http://forum.roadfly.com/threads/126...ctane-gasoline General Motors, Honda, Toyota and BMW responded to our inquiry. Honda’s public relations representative declined to comment on the issue. Toyota noted that essentially all their current models are designed to run on 87 octane. I asked about using 85 octane, available in some markets, and Bill Kwong of Toyota corporate PR told me they would run fine, with maybe only a slight 2-3 percent decline in horsepower and fuel mileage. But 85 octane is usually only offered in markets at altitude (i.e. Denver, Colorado) where the reduced oxygen doesn’t allow an engine to reach full designed power in any event. If you drive a modern Toyota, the octane rating of your fuel isn’t much of an issue. But what about a brand aimed squarely at the performance market? What about BMW? Thomas Plucinsky, BMW Product and Technology Communications Manager told us all BMW engines are designed to run on 91 octane. All performance testing, including EPA emissions and fuel mileage, is done with 91 octane. However, though BMW is all about performance, their motors will run on 89 or 87 octane without damage. The knock sensors pull the ignition timing back and eliminate detonation. There will be a loss of power and a decrease in fuel mileage, but the size of the horsepower loss and the increase in fuel consumption depends upon many factors, such as ambient temperature, exact formulation of the fuel and driving technique, so BMW does not offer any estimates for operation on lower grade fuels. One not so obvious concern, Mr. Plucinsky noted, is the type and quality of additives the gasoline companies include in the fuel. Premium gasolines may have better additive packages which are more effective keeping fuel systems (particularly injectors) clean and working efficiently, than those in regular grade fuels or off-brand products. Using lower octane or off-brand fuel could be degrading the fuel system over time, setting you up for a repair bill down the line

In my country the quality of gas and diesel is not constant, but I have 25000 kms without any problems. Do you plan to order M adaptive suspension? |

Hi Adi
In india I'd consider other alternatives mainly because; - apparently you don't get sport suspension, even on a fully loaded car (after paying crazy 75k) you get base suspension in india. - re: reliability, I've heard its a lot more difficult to get things fixed there than here. This seems to be a brand where things do go wrong once in a while, you want to be sure of the service network. I wouldn't buy a bmw in india. Frankly even my Indica was more reliable than both my bmws here. But I love the way these cars drive! As long as I'm in the US I'll try yo stick to this brand but I can't even imagine buying one in india. Just my perspective. PS: get a Fiesta Classic diesel with the TDCi engine and you'll have lots of money for upgrades like wheels and tyres, lots n lots of fun!

It's official from BMW. The whole ECU is replaced with a new performance oriented one so the warranty remains intact. Otherwise lot's of aftermarket remapping options available which can even take the power to 225 odd bhp but that would void the warranty. |

Hey OP I agree with newoldbeemer...If they are going to be a pain in the ass to fix things..DONT get this car...if you have a good warranty program from the dealer, and are able to get suitable petrol, go with the 328, if the diesel is more predictable, and more consistant overall go with the 320d.
Dont get me wrong the 3 is a great car, but it has some issues that are not quite resolved yet...last thing you wanna do is pay double for a car and then at the very least not get the proper servicing when needed. |

I am sure BMW engines are designed to run on all sorts of petrol and am also sure they would not offer the petrol engine in a market if they thought the local fuel would damage the car and therefore their reputation. I would be more worried about putting low quality diesel into a modern European diesel engine as the fuel companies in Europe have made huge strides to improve the quality of this vile fuel and the engine manufacturers have developed engines to make fully use of these advances.
If the choice is between a bodged up diesel or a stock petrol, I would go for the stock option every time. I confess my only knowledge of Indian roads is as a tourist in the back of a car in Bombay, Delhi and some other tourist sites but confess I do not remember any roads where you could fully (or even partially!) enjoy a 328i. |
