Yeah I know what you mean but it’s hardly progress for the much newer S4 up against a much older RS model excluding the RS5/3 as obviously you wouldn’t expect anything different there.Why was the title “Not a great show for the new diesel S4!”. Did you actually mean “A great show for the new S4 diesel!”.
It is pitched against higher segment cars (RS models) The final conclusion from Matt was, against a supposedly higher end car (the RS4) was”The (diesel) S4 did win the drag race and that is what really matters” (5:10)
No idea mate, they seem to be able to ‘tweak’ all other engines to meet the requirements? I’d have preferred a slightly quieter but powerful petrol engine if it was just the case of putting in some filters but the petrol S4 was hardly the loudest of exhausts, not sure about emissions?@Riko0073 isn’t it the case they couldn’t get it to pass emissions rather than not wanting to put a petrol engine in it?
It beat the old RS4 which isn't hard as most are running 350hp due to coking up!Why was the title “Not a great show for the new diesel S4!”. Did you actually mean “A great show for the new S4 diesel!”.

Mine was firstTwo threads about the same topic?
Yes the S4 diesel was still impressive and maybe a harsh thread title but considering it was pitted against an RS car 2 generations back the old dinosaur did well, no real progress from the S4 apart from sticking a diesel in it, better torque yes but how boring!I think the S4 performance was pretty impressive for a diesel. Audi have taken a different direction with the S4/5 now, to try appeal to a bigger market with improved economy etc so there has to be compromises.

No they haven’t. They couldn’t get the petrol engine to pass new emissions tests and so had to swap it out for a diesel or develop a new engine - not something they’d do with electric firmly into their radar.
This is why it’s only the European versions that are getting diesel and the rest of the world is still getting them in petrol form.
So how does an RS4 pass? Not disagreeing with you just wondering, do they pay add an emission tax?
I wish someone would do a drag race with the B9 S4 petrol car and the new S4 diesel

S4 petrol would smoke it badly Look at the carwow race with New M340i X drive which the old petrol S4 competes with in terms of performance figures .I wish someone would do a drag race with the B9 S4 petrol car and the new S4 diesel

Yes but remap an s4 petrol and you'd be back to square one, can't really compare standard with modded
I had a good race with an RS3 with my mapped 272. It wasn’t pulling massively away from me, only ever so slightly. At first I wasn’t sure if it was an RS as I was expecting it to leave me well behind, but as it got in front I saw the big exhausts hanging out the back and the badges. Although the RS3 sounded absolutely mega. I’d have one of them if I didn’t do so many miles. I’ll see if the video is still on my dash cam.
Which car is which in the video. Does the A4 B9 3.0 TDI or the A4 252 TFSI quattro win?
S4 TDI does 1/4 mile in 13,6. Mine stock petrol S4 B9 does in 12,5-12,6, with box, wagner and milltek nonres in about 11,7-11,8. 0-100 in minę took 4,5 as stock, in TDI one its 4,8 (both draggy measured, same conditions). Those differences are huge, TDI should be around 420/800 to keep up with the preFL.
In addition to the extra weight of a cast iron block. Something I find that many diesel owners don't understand is gearing. When your redline is 4500 rpm rather than 6500 - 7000 rpm you need longer gear ratios or you will find yourself approaching redline in 8th at 80mph. This means the torque amplification at the wheel is lower with all other things remaining constant (e.g. final drive, wheel size etc). So the extra torque at the engine doesn't translate to much (if any) extra torque at the wheel where it matters. What makes these cars feel fast is the surge of torque from 1500rpm, it pins you to your seat right away.
No chance Lol the M340i X drive beat it bad And like I said that’s what the Petrol S4 competes with . The S4 Tdi in my opinion is a huge failure from Audi You buy an S car For character may as well save your money and buy an A4 Tdi.After driving an s7 tdi, s4 petrol saloon and having my own a4 272 tdi remapped, I'd say the s4 petrol is not necessarily quicker in any conditions.
Yeah it sounds better and revs out, but u really do feel the torque deficit in my opinion.
The s7 tdi feels very lazy, so it's definitely not the best car for any type of racing. Yes it's torquey and feels very powerful but it didn't seem like a car that wanted to be pushed so in that regard I'm not surprised the s4 tdi lost as much as it did (still think it did ok)
My a4 272 remapped in comparison feels much more responsive than both and when you downshift it really does kick you back.
Where as the s4 petrol was more about thrills and revving out I honestly felt a stronger kick in my 272. Im guessing it's putting out at least 750nm of torque and over 330bhp so hence I felt mine was quicker than the petrol equivalent.
I also had a drag and roll with a friend's s5 convertible yes I know it's a soft top but I came on top on both. (My cars doing a 4.3 0 60 time)
I think if the new tdi s cars are set up correctly they'd do much better.
And after driving both I'd say the s4 petrol is much more sporty and exciting where the s7 tdi is a laid back lazy cruiser.
I'm sure if they properly optimized the s cars responsiveness it would feel quicker than the petrol and do better on that race, can only imagine what a proper remap would do.
Nope The S4 Petrol Records times close to the low 4 secs mark. The S4 Tdi is slow if you look at online acceleration videos and compare the Performance figures with the petrolThe S4 petrol would reach 62mph 0.1 seconds before the S4 diesel. I would hardly describe that as "smoking badly" rather "just beating".
Unless you are saying that you think Audi's quoted figures are widely wrong.
I've seen Audi understate 0-62mph times before, so either cars figures could be incorrect. Loads of people in the comments seems to be calling for an stock B9 S4 petrol vs stock B9 diesel. I guess that is the only way to see for sure.
Let's hope Carwow or another channel arrange such a drag race. S4 Petrol vs S4 diesel

Here’s a comparison

If you look at these stats off automobile catalogue you'll see the s4 tdi does 0 60 in 4.5 compared to 4.4 for the s4 petrol.
The differences in real world probably won't be noticeable as the diesel still has significantly more torque, the pull is much stronger imo and as you can see the petrol does get the better though as the speed increases but I still wouldn't say it's getting smoked.
In gear tests also show the s4 tdi being the quicker car in those tests.
At the end of the day they are both 2 completely diff cars! Both have their merits..
Great to see some more objective analysis backed up up by statistics. Definitely not objective to state that the petrol “smoked” the diesel as your post suggests.
In terms of in the real world owners don’t tend to have drag races or go over 70mph /120kph so largely irrelevant to 95% owners so my prediction is that in the UK the new diesel S4 will sell just as well as the old petrol S4 (unless Brexit related tariffs bump up the price significantly) but let’s see what the sales figures show (I reserve the right to be wrong )
Fair enough mate But Honestly after driving a Tdi don’t think I could live with one I just love the sound too much of a petrol . If I was Gonna buy a Diesel It would be A Bmw not an AudiIf you look at these stats off automobile catalogue you'll see the s4 tdi does 0 60 in 4.5 compared to 4.4 for the s4 petrol.
