Golfer Posted March 15, 2007 Report Share Posted March 15, 2007 Right what would it take to make the S5 as quick as the RS4?. Remember same engine: would a simple remap be the answer?. Link to comment Share on other sites More sharing options...
gizze Posted March 15, 2007 Report Share Posted March 15, 2007 Considering some RS4's are not putting out anywhere near the quoted figures I would think it would be very possible with a cat back and remap. Link to comment Share on other sites More sharing options...
garcon magnifique Posted March 15, 2007 Report Share Posted March 15, 2007 Careful Gizze - suggesting Audi (rather than BMW) might be guilty of overstating output could get you linched on 'ere mate... Link to comment Share on other sites More sharing options...
gizze Posted March 15, 2007 Report Share Posted March 15, 2007 BMW figures are well out as well, the 335i is rated at 306bhp but so far all of them have been tested at 330bhp. I bet the new S5 puts out the same as the RS4 anyway, but they won't want to steel the RS cars thunder. Link to comment Share on other sites More sharing options...
Golfer Posted March 15, 2007 Author Report Share Posted March 15, 2007 I have tried to find out the weight of the S5. The RS4 is 1650Kg (saloon) with 414BHP = 4.8secs 0-100Kph 306g/km and the S4 series saloon is 1660Kg with 354BHP = 5.6secs 0-100Kph 322Kph!!!!!!!! then ???? S5 with 354BHP = 5.1secs 0-100Kph 298g/km should be between 1525/1585Kg by my reconing, any comments. PS) Emissions figures dont add up for the S4 and S5? or am I missing something Link to comment Share on other sites More sharing options...
rottenbend Posted March 15, 2007 Report Share Posted March 15, 2007 On the German configurator it states a weight of 1630Kg. But this doesn;t seem to tie up with the figures... Link to comment Share on other sites More sharing options...

garcon magnifique Posted March 15, 2007 Report Share Posted March 15, 2007 Is the S4 354bhp? I thought the S5 was using the 4.2FSI unit, which is different to (or at least a development of) the S4 unit? Link to comment Share on other sites More sharing options...

garcon magnifique Posted March 15, 2007 Report Share Posted March 15, 2007 Well kind of yeah. The S4 - as far as I know - has the 344 PS non FSI 4.2 V8. The S5 has the 354 PS FSI 4.2 V8 (similar to the one in the A6/A8 4.2). So there's a difference of 10 PS and quite possibly the power delivery between the S4 and S5 - so direct comparison between S4 and S5 performance figures to extrapolate the weight of the S5 ain't gonna work. At least not accurately. I think. Link to comment Share on other sites More sharing options...

[/ QUOTE ] Because it's just about to become obsolete, so they aren't going to do any work on it. Changing the engine would probably invalidate the type approval which would be VERY expensive to re-do, and with very low sales of the S4 since the RS4 became available and the model dying later this year there just is no justification to spend the money...

I doubt there will be much discount to be had on a new S5. Link to comment Share on other sites More sharing options...
Merlot Posted March 26, 2007 Report Share Posted March 26, 2007 Zippo on an S5. My S5 spec is £46k and a similar S4 saloon would be £43k list but £38k actual so the spread is really £8k. I'm tempted by a low spec 3.0tdi with a remap or may just not bother given the lack of adaptive damping (the magnetic ride on my new TTR is brilliant BTW).

[/ QUOTE ] Merlott, I have reservations on this car myself, the remapped 3.0 TDI is going to give you 285BHP which should improve performance, but I've been there and economy can suffer, those figures for the diesel are somewhat optimistic from my memory.

Merlot Posted March 27, 2007 Report Share Posted March 27, 2007 The more I look at the price list, performance, economy (range on a tank from my perspective) and things, the more I am steered towards a low spec 3.0tdi sport at c£36.5k without nav. With an S5 I am £8k more incl nav (S5 would need it for resale, 3.0tdi not IMHO) for my spec but I will be filling up after 250 miles rather than 400. Which way are other people going?

Merlot Posted March 27, 2007 Report Share Posted March 27, 2007 To assess all round performance of a car and compare petrol to diesel, I average power (bhp) and torque (Ib/ft) and divide them by kerb weight. The S5 is 207 and the 3.0tdi 188. A remapped diesel usually gives 20% more so that would give the diesel 10% more than the S5. Ok it would probably still be slower in a straight drag race but in normal driving a remapped diesel is likely to be quicker....can't believe I said that.

Scotty Posted March 27, 2007 Report Share Posted March 27, 2007 I wonder when Audi will cash in on it diesel success at Le Mans. Perhaps they've something in the pipeline IF they win this year. Surely a diesel S5 (i.e. all the suspension, brakes etc plus a tuned oil burner) and a diesl TT has to be the way forward? Link to comment Share on other sites More sharing options...
Merlot Posted March 27, 2007 Report Share Posted March 27, 2007 Its a bit of a decision - I wish the diesel wasn't so fast! Trouble is it could also do with being a bit cheaper than the S5 spec for spec than it is. Link to comment Share on other sites More sharing options...
