What do the prefix numbers mean?

[Rupert49]

A general question here ...

I've noticed alongside the make and model descriptions of various different Audis that there is a number, usually 30, 35 or 40, that precedes the 'TFSi' or 'TDi' part of a model name.

What do these numbers mean? I can't get them to relate to engine sizes, but they must have some bearing on the model in question.

It appears it is the newer engine transmission designations.
For the new Q3 as follows:
Petrol ones:
1.5-litre 148bhp ‘35 TFSI’,
2.0-litre 187bhp ‘40 TFSI quattro
2.0-litre 227bhp ‘45 TFSI quattro
Turbo Diesel ones:
2.0-litre 148bhp ‘35 TDI’
2.0-litre 187bhp ‘40 TDI quattro

I think I read something about this on here a while ago. These numbers are quite a new development and do relate (I think?) to the power. But not sure how.

See the post above yours!

As Peter said it designates the power of the car. In my opinion it looks stupid and is pointless. Not much sense behind it.

Ye cant afford a S3..........lol

im sure its to ease into hybrid engines where cc alone is less relevent when combined with an electric motor so putting power output instead.

IMHO it’s utter ******, hence see my rant here:

Anyone looking at the website will be like “just tell me the ****** engine size ***”

Guff.... they've been using these engine designations for years in other countries

Can you debadge the cars on new orders but keep the model badge? So you don't get the silly numbers?

Wouldn’t have been quite as bad if they’d directly related it to the power numbers

Eg.

100PS+ = “10”
150PS+ = “15”
200PS+ = “20”

and so on.......

Can delete technology or model and technology on configurator

I had 2 options:

1) Deletion of engine technology designation at rear
2) Deletion of model and technology designation at rear

I did option 2, as I think it looks more sleek on the back end

Interesting debate, guys .. thanks for looking in.

Personally I agree with those who feel the numbers are pretty meaningless. Here in good old Blighty we've used bhp or hp for donkeys years and more recently the spec sheets have been quoting power in ps numbers, which is close enough I suppose, except when someone asks how powerful my S3 is. Do I say 300 (ps) or 296 (bhp)? Most petrol heads work in bhp, so I probably say something like: 'Just short of 300, mate'!

Quoting bhp, or ps, may well impress mates in a pub it is torque everyone should be interested in.
The new numbers have also been around for years in asian countries and are only aligning us with them and the outpots of electrically powered vehicles.
There is always the choice of having the badges kept or not fitted at the factory. Personally I would not lose any sleep over them as, after all, they're only badges. More things in life to worry about...

I've had this "dilemma" for a while now because I've changed cars a few times. PS is always the round easy number, but everybody asks what the bhp is. I like to give an accurate answer so I usually give the PS figure then depending on who it is I'm talking to I will also give the bhp.
The difference has never been more than 4 so it will not make any difference to that person. From now on if anybody asks the bhp I will just tell them the PS and leave it at that.

I agree torque is a much more relevant indication of the driveability of an engine, but it means nothing to most people when compared with bhp.
Diesel engines always have more torque than an equivalent petrol engine, but one would come across as a bit of an **** boasting about the torque of their diesel Insignia down the pub.
