In the past BMW's badges always reflected the engine size. (I've had 5 so I know).

These days it purely is to differentiate between the different models in a range.

The BMW 3.0 engine now exists in various states of tune and thus we have currently in the 3 series around the world (not all of them in Oz) the 325i, 328i, 330i (actually a different engine to the other 3 & still sold around the world) and the 335i (twin turbo, no single turbo version exists)

This is the same principle as VW these days that sell the 2.0 TFSI in versions 125kw, 147kw, 155kw, 169kw, 195kw (188 in Oz) & 200kw around the world.

VW are also playing silly buggers with engine badges these days (when they bother to put them on).

The TSI badge used to mean a petrol engine with a Turbo AND a Supercharger (ie 1.4 Golf GT), but these days it only seems to mean petrol and turbo (mostly without a supercharger as well, but some with).

TDI badges have their own secret codes too. The general principle is the more red letters the more powerful the engine. So an engine with silver TD and a red I is more powerful than one with all silver TDI, but one with all red TDI is more powerful again (guess what colours the letters of my TDI are ? )

the SI refers to throttle plates in the intake manifold which move to change the flow of the air in the intake manifold independant of the position of the actual throttle body. They improve fuel economy and torque at constant velocity in small engines. I don't know what the S and I actually stand for but I imagine it would be something along the lines of Smart Intake. Superchargers have nothing to do with it. The F is when the throttle plates are further forward in the intake manifold and the T does indeed mean turbo.
FSI, TSI, TFSI.

... I don't know what the S and I actually stand for ...

Stratified Injection perhaps, as opposed to the more common port (homogeneous) injection.

Yeah! That makes good sense! It rings a bells too. I think I've heard Fuel Stratafied Injection somewhere before. That might be what the F stands for too!

I thought FSI was Fuel Stoichiometric Injection.

Slight performance increase ????? Mate, it should be a huge performance increase .... MK5 GTI 0-100km/h 7s (averaged DSG & man) R20T 0-100km.h 5.7s (using S3 figures which is less powerful)

And I agree Mk3 is better looking than Mk5

plus S3 figures is based on manual...so you can safely say DSG will be quicker too...

I'm not sure it will be. When the DSG first came out all the specs said it was quicker, better fuel consumption, lower CO2 etc. But now for the MK6 the DSG offers only the same or slightly worse acceleration, worse fuel consumption and worse CO2.

The UK specs for the GTI for example are:
6.9sec 0-62mph, 7.3 L/100km, 170g/km
6.9sec 0-62mph, 7.4 L/100km, 173g/km

I thought FSI was Fuel Stoichiometric Injection.

I googled it and it is Fuel Stratified Injection but it was called Fuel Stoichiometric Injection in The Netherlands when it was first released there as not to be confused with something Mitsubishi was marketing at the time.

Stratified means ranked or graded into the area of distribution.

Stoichiometric means the correct ratio between 2 chemicals.

what enlightening fun!

Not necessarily..... VW have always made big performance noises about DSG being quicker than a manual. And it does change gears quicker than a manual and in VW's tests .... starting the clock when the car starts moving it has been quicker ....

HOWEVER when VW took the press to a drag strip to "prove" their claims the manuals beat the DSGs over the qrtr every single time ........ (I can provide a link to the press report on this)

That bit of lag (and the press still reports on this in every test and I experienced it on a recent testdrive of the Q5) of a DSG upon pull-off when the lights turn green means the manual is gone ......

SO timed against the clock from when movement starts ... yes a DSG is quicker

BUT timed on a drag strip, the manuals still beat the DSGs .... PROVIDED the driver knows what he is doing as the DSG allows even tools to shift quickly

Either way, I'm comfortable that the R20T/whatever will do it in a time around 5.7s ... ... and that is before I let the tuners near it .....

More R20/R45(!) rumours

has anybody thought of VW using Audi's 2.5L turbo??

Heres that latest rumour

WoooooooooooooooooooooooooW!

FSI = Direct Injection normally aspirated.

TSI = the new range of turbo, turbo+supercharged engines.
