Between Two Cars: Audi A4 2.0TFSI vs Audi S4 V6 3.0TFSI // Revo

Показать описание

We took the latest Revo B9 A4 & S4 development vehicles to a private proving ground and put them head to head. A stock S4 with 354PS up against the B9 Audi A4 2.0 TFSI with Revo Stage 1 Software; +54PS and +48LBFT over stock and a whole lot more fun to drive.

Fuel: Shell vPower 99RON
Tyres: Road
Track: Dry/Damp

Note: During development dyno testing, the Audi A4 B9 displayed consistently higher power and torque than quoted by the manufacturer of 252BHP & 274LBFT. Actual stock figures seen were 286BHP 290LBFT.

Hmmm.... Is it just me or does this look suspect because they don't show the whole race from beginning to end?

bahaha what crap. 4.9 second 0-60 for the S4?! LOL that is BY FAR the slowest 0-60 time I've seen ANYONE report for the S4. Manufacturer claims 4.4 is a *conservative* number on the S4 0-60. Most times I've seen reported on the forums are 4.1-4.5. This video is Revo trying to sell their product.

Its possible because of couple of reasons, the main reason is gear box software update. With remap A4 should be able to reach ~-280-320hp. Add the lighter chassis, and it is in the range of power/weight ratio to S4.
Now the main thing is the proper gearbox remap after the engine was tuned. If they adjusted the gearbox properly it is possible to beat stock S4.
S4 engine might have more power, but that power is achieved at different engine speeds and that is limited by the gearbox. A4 was tuned to drop the gears at peak power/torque. You can tune a lot of weaker cars to outperform the stronger ones, simply by adjusting the gearbox. In majority of the cases the problem is the reliability and fuel economy on the normal driving conditions as well. And while you can tune the engine, a lot of the cases gearbox becomes the bottleneck especially the automatic gearbox if it is tunable, then its good, but some of those are not tunable...

And as for A4, even adding a downpipe alone will give you extra 20-30 horses.

4.9s on the S4 isn't the best run I've seen, but people don't seem to understand the power of weight difference. That A4 could be like 200lbs lighter. A bigger engine doesn't automatically equate to better performance. A tuned S4 is a different story, but it's not that surprising at all to see a tuned A4 beat a stock S4 due to difference in weight and optimized timing/power delivery.

please can you advise where the B9 S4 Revo upgrade is up to please?

S4 does 4.3 sec to 60 mph and quarter in 12.6 secs. you did not launch properly, maybe it was on purpose so your product would look better. But anyway, very impressive numbers for the A4.

how did the DL382 handle with more than 400nm？ is it safe ? As I know, the max is 400NM for DL382

Great video showing small incremental but effective results

Hi, I was wondering if you can help me. I have an Audi A4 2020 2.0 T 40 TSFI quattro. I want to tune it but I'm wondering how it works because the Audi A4 2.0 T 45 TSFI quattro to my understanding has the exact same engine but its electronically more limited by Audi. Can I tune the 40 TFSI to the same potential as an 45 TSFI ? I was going to buy the IE ECU Stage 1.

"Software; +54PS and +48LBFT over stock" - vid claims 81bhp and 65lbft. Are the figures you stated entry level results (low octane fuel etc) and the vid figures best case?
Good results from the sleeper A4 though. Is this a revised 2.0T VAG lump over the 7 GTI/S1 power plant?

Ok this could be a real race lots of people saying it's fake. The driver makes all the difference. They should have done multiple races while switching drivers.

How about audi a4 b9 3.0 tdi 272bhp? it would be interesting to put this again new RS4

linkmarine

I'm impressed! But the wagon supposed to be heavier than the sedan right? So if it was sedan to sedan, the 2.0 will pull further, am I right?

vincentlonbird

I have question too. When u will have software for 2.0 tdi, 150hp and 340nm Skoda SuperbIII /VW Passat b8. Still not have any software about this model, just have for Golf/Octavia/Leon 2.0 tdi 150hp and 320nm. Its different model this engine with 340nm from this 320nm or what?
