Default Rev Matching Auto S5

Would like to know if the auto in the S5 rev matches on downshifts. Any numbers on how quick the shifts are? Am looking to pull the trigger on a new S5 come Spring time.

Thanks

Default The automatic is the conventional torque converter variety, rather than a DSG/SMG/F1 type.

If you use it in manual mode, it does a decent job of not jerking you much - but it's not the throttle blip action to the extent of the others above. Those use regular clutches and synchros like a manual gearbox, but hydraulics and solonoids to replace the third pedal and your left leg. They must rev match or face unacceptable wear to the clutch and synchros.

The S5 will change to a supercharged V6 late this year depending on whose reports you read, and with it will come the DSG style gearbox option.

Not sure if that answers the question.

Some torque converter manumatics will throttle blip when downshifted[e.g., g37.] I'm not sure if the 6sp Tip in the S5 does.

I had read on an Audi Press release via Fourtitute that the S5 coupe is going to retain the V8/Tiptronic transmission through the 2010 MY. The v6-3.0T/DSG combo starting in the coupe in 2011 MY[Cabriolet in 2010 MY.]

The last issue of AutoWeek had an article about one of their writers having a brief drive in an S5 coupe with a 7-spd S-Tronic[DSG]. The article suggested it had the V8 engine but it wasn't suggested that combination would make it to a production car. The article affirmed the 6-speed tiptronic will continue in the US.

I'm also getting a 2009 or 2010 MY S5. I'm watching for further details about the 2010. [Paramount to me is getting the V8.]

Default my S5 Tip (08) appears to throttle blip on downshifts...

noticeably at slow speeds, so you get that same sort of braking effect you'd notice with downshifting a manual.

Default All tiptronics since '01 (or '00, forget which year) have had the blip feature.

Not as good a job of the newer DSG gearboxes but does a pretty smooth job of blipping the throttle when downshifting.

Default The '94 Alfa 164 auto matches revs, but doesn't blip. It also downshifts if braking

exceeds a certain threshold, holds gears in corners, and generally is a tolerable automatic. The downside is absolutely abysmal fuel economy ZF gearbox, so this was available to everybody using ZF for some time, but not everybody wanted to take the mileage hit.

Default Drive Select in Dynamic Mode does some tricky things on downshifts/braking...

Would love to see some technical details of what it does specifically, but it does kill fuel economy...

...and you've always got the paddles.

Throtle blips on downshifts only in Sport mode, not in Drive.

Default The S5 tip does blip on downshifts. The newest feature on the RS6

(which is a tip) as well as on the newer DSG boxes like on the TTS are blips (spark retardation)on upshifts to smoothen out acceleration. Listen to the cars as they pass you and upshift - they make a great sound.

To tell you the truth, I now can't really tell the diff between the tip and the DSG on the road. The tip has really improved.
