BMW are one of the very few car companies pushing diesel technology in Malaysia, but even they have not put an oil burner in all of their models. For the longest time, diesels have only been available in BMW sedans, hatchbacks and SUVs. Then their convertibles started to feature oil burners. Then the diesel engine was finally offered in the 6-Series.
Today, the only BMW car still not available with a diesel engine is the BMW Z4, not even in the latest E89 variant. Not until now anyway – what you see above is an attempt by an aftermarket tuner to join in on the whole green movement that’s sweeping Planet Earth.
It’s called the AC Schnitzer 99d and it’s essentially the new E89 BMW Z4 with its engine bay equipped with the 2.0 litre turbodiesel engine from the BMW 320d. The stock numbers have been tuned up to 190 horsepower and 420Nm, but yet the 99d in the name refers to the 99.18g/km of CO2 emissions the car is rated to produce. 0 to 100km/h can be hit in 6.9 seconds, and rated fuel consumption is as low as 3.8 litres per 100km combined.
AC Schnitzer is referring to their green tuning attempts as “Efficient Performance”, and a diesel engine is not the only thing that went into the Z4 – lots of weight reducing work was performed as well, shaving the Z4’s weight off by 230kg.

astonishing, brilliant and superb.
very powerful yet economical and surpsingly very very low emission level.
before anybody get started on “owwwhhh..diesel quality in malaysia so bad..blablablaba..”, just consider this, BMW sell their cars with diesel engine option here (albeit being tuned to work with our diesel), why doesnt the other makes do so? i believe chiefly because they didnt bother..using the public misconception and put it as an excuse “poor diesel quality”..but they do sell their diesel (even petrol direct injection) to the north america market, in which they mainly use fuel that are no better than us. for example, the petrol use there are ron85, ron89 & ron91..i bet their diesel aint euro4 as well..
ya i think really fakup when got see new article about diesel car, people start yelling about malaysian euro type, really annoying shyt
Firstly, you need to understand that fuel quality has NOTHING to do with octane numbers.
and North American octane numbers are PON rating, not RON like ours.
a PON 88 rated fuel (ie. Regular) is about RON91.
You have also got to understand that with BIG engines (as in North American cars), you can run lower compression and ignition timing to make power, reducing the requirement for higher octane fuel. Smaller displacement, higher compression and timing advance common in our domestic cars need higher rated fuel.
(as an aside, I have begun to notice a higher failure rate in a lot of late model Protons, especially the knocking prone 4G13 and 4G15 engines, like con rod failures, main bearing failures….no doubt some due to the move from 97 to 95 octane fuel – I remember calling the Transportation ministry bullshit when they said all protons can run on 95 octane fuel – I had a 2001 FI 1.5L Wira which I had to detune to run 95, even then it was knocking on certain hot days on load.)
When someone says fuel quality, they are talking about dissolved deposits like sulphur
oh yeah…. US/Canada diesels are ULSD rated (ultra low sulfur) which is euro4 since 2008(canada was 2006)…in fact so high that one year (forgot which year…think it was 2006) the VW TDI was not allowed to sell due to diesel emissions that were higher than allowed.
BMW diesels work here…Ford Focus diesel too…so what happened to Japs sedan with diesel engine? the truth is, they do not want to really want to do so…
North America popular cars still mid-size sedans and so-call imports (japs)..camry, accord, civic, corolla…those model not actually low compression engine no? mitsu lancer @ inspira is an engine that is tuned to work with low ron rating..
sulphur content..how sure are you those in the states are better then us? if you say europe, yes, i might agree…north america? no..i dont think so..
The higher performance japanese models require premium fuel (ie. PON92+/RON95-97)
Those from Honda higher performance engines. They can still run lower octane fuel, but at a lower power output as the engine management pulls ignition timing to match.
For example the Acura TSX (Euro Accord) needs premium fuel to run its 11:1 compression 200hp K24 engine, while the normal Accord (what we get here) runs regular fuel on its detuned version of the same K24 with 177hp. That one has 10:5 compression ratio. On top of that, the power reduction also comes from less agressive timing advance. Even Honda North America is dropping its high reving VTEC motors in favour of larger displacement units ….like what the new Civic Si would have. Even toyota is already outfitting the sportier Corolla XRS (our Altis) with the Camry’s 2.4L engine.
The popular Civic 2.0 only has a 9.6:1 compression ratio…which isn’t high by anyone’s standard. (in fact my Satria has higher compression ratio)
The higher octane rated fuel is usually due to the new blends of ethanol (10-15%) in fuel. Ethanol has higher predetonating resistance hence the higher rating. They have phased out MTBE in fuel additives and moved to ethanol. Ethanol has less energy content so the higher knock resistance comes with reduced mileage.
The Accords and Camry’s may still have high compression engines, but they are also larger engines. 2.4/2.5L are standard mid-sized engine, they don’t have the smaller 2.0 like we do. Some of these need premium fuel to get the most of out it. I can already feel the difference when I use RON92 (when it was available) in our Accord 2.0 here. 95->97 is not a perceptible difference.
How sure am I about diesel quality there? Well because I used to live there, and even now, i visit few times a year….. You can always google if you don’t take my word for it.
California and Canada has some of the strictest emissions regulations on the Planet…. often higher than Europe. Cars sold there have exceeded European standards for ages. European Diesel cars can run on North American diesel. Which is why VWs are so popular there.
I don’t know if you spend any time in North America to hypothesize what goes on there.
I comment based on Facts. I appreciate if you would want to call my hand, please do so with facts as well.
You are so ignorant it hurts.
RON and Euro are two different worlds altogether.
RON is a measure of how easy a fuel burns. Euro is how much sulphur is in the fuel
Sulphur in the fuel creates emissions and is bad for the high pressure injection systems in diesel commonrail and petrol direct injection engines.
BMW has the time and money to test their cars to run on Euro 2. Euro 2 is just the absolute bare minimum needed for the engines. Other makes don’t have the money to test extensively hence prefer to wait until a higher euro grade is reached rather than bring in the models and then deal with warranty claims.
USA you blinking ignoramus has their own set of standards some which are even stricter than Euro standards
isn’t that great? powerful coupe with great torque, yet getting such good fuel consumption. if only we hav Euro 4M diesel now. best of both worlds man!
here comes the man mosar said
“The stock numbers have been tuned up to 190 horsepower and 420Nm,”
wow….. imagine having that in a 320d…….. can rival a 325i!!!!
how can BMW shave 230kg?
Diesel Engine is much heavier than its petrol engine which is built on all aluminum
must be some spartan car then
probably lost its folding hardtop, replaced with fixed carbon roof or something :)
Actually, a BMW 330i engine is 133kg, the 330d engine is 153kg, just 20kg more. (Both plus turbos, fuel injection, manifolds, etc.) For comparison: The E36 M3 (US-spec) was 215kg (grey casting block & aluminium head)
But because of the much bigger torque of the diesel, the gearbox is heavier too….
BTW: Modern diesels are entirely made of aluminium and magnesium.
schweet , hope its equally as refined as its petrol brethren..
Why not many people buy Ford Focus TDCi?
Dis is bcoz de model n design of Focus is so outdated n ppl r waiting for Focus 2012 which in my opinion Ford shld start produce it dis year n not next year. Anybody won’t want their car to suddenly depreciate n outdated a lot after 2 yrs bought it bcoz all new model is started 2b on de road. Problem wif Ford is their product development time until production is too long n by de time, not so interesting anymre. They shld bring new Focus in 1 year after new Fiesta to maintain de excitement of their product portfolio.
230kg weight loss? what did they throw out???
thats like all the glasswork and body panels on my satria!!…
I’m confuse. Is this means we cannot buy diesel bimmer (in this case) due to our crappy diesel gasoline? So why still bringing the diesel variant in the first place? If we upgrade our diesel quality, is this means the price of diesel will increase as well?
Mercedes had some problems in the past in Thailand, because the guys there pour water in the diesel to make more profit. In this high pressure fuel injections, the fuel is used as a lubricant too. Water in the diesel therefore has the same effect for the injection pump as water in the engine oil has for the engine…
Only to point out the difference old/new: An old Mercedes 911 lorry has an injection pressure of 120 kgf/cm2. A modern diesel engine has an injection pressure of approx. 2000 kgf/cm2…
Our poor diesel quality will not kill the engine or injection, but the sulfur will kill the particular filter in the exhaust…
see, a turbodiesel is more frugal but more powerful than those prius & insight. . . .
3.8L per 100km! That’s 1315km per full tank of 50L. Unbelievable!
Whatever engine you put into this car… its still a beauty!!
lean,mean,green machine….
these tdi is best used with an mpv vehichels!
