HI all, I noticed that the specifications of the e90 on the BMW international website is different from the ones given in Malaysia. The major differences are the acceleration,hp and fuel consumption.E,g; Malaysian InternationalAcceleration 0 - 100 km/h (in s) 9.8 8.2Max. power (bhp@rpm) 156/6,200 170/6,700Links to the technical data.http://www.bmw.com.my/com/en/newvehicles/3series/sedan/2008/allfacts/engine_data.htmlhttp://www.bmw.com/com/en/newvehicles/3series/sedan/2008/allfacts/engine/technical_data.htmlI wasn't bothered by this until I saw the 320d today at the showroom and found out that it's 0-100 is 8.0 s. How could the diesel version be faster than the petrol one.Now I feel cheated.Anyway, any ideas of why the inconsistencies? Thanks in advanced.
Different Specifications. Why?

I think the the higher HP version is the HPI version with a more powerful, higher tuned engine... Don't think this version is widely available..
The 320d diesel version is a turbo diesel.... btw, it has better consumption compared to the 320i..

The Singapore version is the latest 2.0 4-pot valvetronic which also drives their E60 520i. I only knew about it cos Bernard of BVO said he can't tune that one yet. If it's HPI, then I can understand why it's not available here, cos our Euro 2 fuel not quite suitable for HPI unlike S'pore which is Euro 4 compliant already.

Dont know about the diff between the two 2.0 Litre versions but I do want to comment on the diesel.
Dear Bro styLmntz,
I think like everyone else, you might need to readjust your thinking on diesel engines.
Traditionally, diesel engines have high torque but low top end power, and with petrol engine, the reverse is true. They have a very narrow power band. But torque is the main factor that determine acceleration times. One other advantage of diesel engines is their low fuel consumption. The disadvantage of diesel engine is the noise and particulate emission.
Off late, there have been significant advances in diesel engine technology such that they are able to match petrol engines in the main performance areas and surpass the petrol engines in overall terms with their inherent high torque and low fuel consumption. The clicketyclack of the diesel has been somewhat banished. Well at least you dont hear it from inside the car. The black soot is now significantly less especially with Euro4. Diesels are no longer the dirty and oily lumps they used to be.
In fact for many mainstream cars, the diesel outperforms a petrol engine of a bigger capacity. Many reviewers of diesel car have been pleasantly surprised at the result. Many have rated the diesel version as being the better or if not the best of the range.
BMW and Audi have even raced successfully diesels, which no one thot possible just a few year ago.
Despite the recent price hike of diesel (diesel now cost more than petrol) in UK, diesel car sales have matched or beaten petrol car sales. This is despite the fact that all diesel incentives have been removed in many countries across Europe.
During my drive overseas especially in Europe, I drive exclusively diesels or to be precise, turbo diesels.
It is only the public perception (especially in Malaysia) that is left to be addressed. For Malaysian I believe comes from the fact that diesels have always been seen as more suited for commercial vehicles.
So it should not be a surprise to anyone anymore why a diesel may have better performance than an equivalent or even higher capacity petrol engine. Least of all the acceleration times.

I have to agree with Saat. Even a few years back when I test drove the 530d and 530i back to back, the huge torque on the 530d was truly amazing. The 530i felt underpowered after that. You can expect the turbo diesels to be the mainstay of next generation BMWs.

Saat, while I had every confidence in the 530d, I heard so many negative things about diesel quality in Malaysia. I believe my fears were well founded as I have seen a couple of 2-3 year old 530ds clattering away with huge plumes of black smoke. The cars can still blaze away, but with too much aplomb in terms of the black stuff. The crucial thing about diesels though, maintenance is all too important.
I hope diesel quality hugely improves by the time the next generation BMW diesels arrive.

I fully disagree.
With newer technology, we are able to utilize diesel alot better.
To name a few:
-8 gears fast-shifting automatic transmission to maximise the power band of diesel between 2-5k rpm, and better gear ratio.
-Direct diesel injection to reduce noise from knock. (Diesel engine knock naturally)
-Faster car computer electronic for better ignition and emission control. New diesel engine can surpass the strictest emmision control in Europe while Gasoline still having a tough time to meet the requirement.
Despite diesel have more BTU per unit than gasoline (aka petrol) which give better fuel consumption, it is still distance away as "performance fuel".
Audi did a great job in the LeMans 24 with their turbo diesel engine, but that is to proof the diesel is equal, or better fuel efficient & reliability. Not more powerful.
Telling me "torque is the main factor that determine acceleration times" is just kids talk.
If you haven't already know, HP = torque x RPM / 5252, which indirectly, HP IS EQUAL TO TORQUE.
The different is RPM. And diesel engine just cannot rev.
If I want a fuel efficient, quiet, good for environment, haul 5 persons in a car with full luagage in the rear & long distance cruiser, I would get a diesel.
For anything else, I prefer a 8000rpm happy gasoline engine.
p/s: How about a diesel car in Gymkhana ? high "acceleration" wat...
Peace

Bro, no need to attack my statements. Try and address the original poster's query. I just dont see what you are disagreeing about. The first part of your postings are the details of what I said about "significant advances in diesel engine technology".

it is also not uncommon for distributors in western countries to quote performance figures of manual transmission, without indicating so. this is acceptable i suppose when stickshifts are popular in those markets, whereas almost nonexistent in asian markets.
320d is faster than 320i because of the siput la... put a snail onto the 320i and see what happens

AFAIK, diesel engine has no spark plugs. It self-ignites due high combustion chamber pressure... Unless it's something new..
HP is proportionate to TORQUE, not equal... as the equation shows. However, in a diesel, high useable torque comes in much earlier which is good for street use and even for track.
Just watch the dog fights in the WTCC races between the SEAT LEON TDi and the BMW.. The SEAT can pull away effortlessly at the straights... that's faster acceleration..
Diesel engine doesn't need to rev.. It's good enough as it is..
