New 2.0 TFSI Engine & 7 Speed DSG

[LiFers]

Audi (VW) have just announced some new technology premiereing on the Q5.

http://www.thetorquereport.com/

Engines
"The 2.0 TFSI has been entirely redesigned. The four-cylinder engine unites three high-tech features - turbocharging, gasoline direct-injection technology and the innovative Audi valvelift system for variable control of valve lift.

The high torque of 350 Nm (258.15 lb-ft) is available at 1,500 rpm and remains constant up to 4,200 rpm, with performance peaking at 155 kW (211 hp). The Audi Q5 2.0 TFSI sprints from 0 to 100 km/h (62.14 mph) in 7.2 seconds, reaching a top speed of 222 km/h (137.94 mph). On average, the vehicle consumes just 8.5 liters of fuel per 100 km (27.67 mpg)."

Transmissions
"Audi has built innovative technology into both the 3.0 TDI and 2.0 TFSI - the S tronic, a new twin-clutch transmission with seven speeds. This high-tech component can execute gearshifts in just a fraction of a second while offering exceptional comfort and high efficiency. Drivers can let the seven-speed S tronic shift automatically or select gears manually, when desired with rocker switches on the steering wheel."

If you look at the specs you'll notice the 3.0 TDI (Common Rail) makes 500 Nm, and the recently released 7 gear dry DSG is only rated for 250 Nm. The existing 6 speed DSG is rated for 350 Nm, so this new 7 speeder is a beast, and brings DSG to a long array of models that were previously too torquey.

i like my engine and DSG being torquey.

i just think 7 speed is too much. the DSG is going to keep clicking up down up down. it wont allow enough room to rev the engine out and will just cause constant gear changes for "fuel economy" esp in city traffic.

I noticed the same even on the 6-speed DSG of the GT TDI I was given as a loaner ... around town it fidgets & farts trying to decide which gear it should be in. Truth to tell ... wasn't very impressed, but then ... I've never liked 'slushboxes'.

350Nm @ 1500RPM in a petrol engine.

Jesus.

It's going into a heavy SUV. If they want it to feel responsive they have to tweak the tradeoffs to give them maximum torque down low.

Well ... yeah. That's the point, to keep the engine in it's most effecient range. You can always manually shift if you want to ring its neck.

If you give it a couple of days the transmission learns your style and that goes away. And you can manually shift of course.

It would be good if that last gear was an overdrive, roughly say 1300 rpm @ 100km/h.

If not, even the 6 box changes gears too often, 6th gear at 60km/h?

Maybe they should consider fitting 1960's 2 speed Holden Powerglide gearboxes then?

I love the 6 speed DSG with the TFSI engine, it is pretty well always in the right gear at the right time. If VW were to introduce this updated TFSI & 7 speed DSG in the next VW I was interested to buy I'd grab it without hesitation.

I don't mind all the gear changes in my DSG - I have a hard time convincing passengers that it's actually changed gears at all! I end up calling out the changes as they happen - they still don't believe it's changed gear, so seamless are the changes!

It's not 'til I start changing manually that they can even feel the changes. 7 gears shouldn't be that big a deal.

And I agree with some of the comments above - the 7 speed spread of ratios will keep the engine at/around that 1500rpm. Use 'S' if that's no good!

Besides, the 7 speed is apparently a dry clutch system, so is massively lighter (and doesn't need 1200 litres of oil to refill!).

As per post above, the 'Audi' 7 speeder is not the dry clutch version as the engines would overpower it. This is a totally new dsg of which there has been very little detail announced.

FYI the dry clutch 7 speed dsg is approx 20kg lighter than the 6 speeder.

Wow - VAG not using the same component across 5 brands??!
Sorry, didn't realise it was a new 'box. My bad.

The current "Sports" mode in the GTI DSG is completely useless unless you are wringing its neck on a mountain pass or on the track.
What I would like is a sports mode that I can use around town to keeps the revs a little higher than they are currently in "Drive".
Change down when revs drop below 2500 etc not 4500 as the current sports mode does.

[moguzhan]

sports mode sucks on the DSG.

whack it in Sports on city traffic and gas it, the car jumps gears, 3,4,5,6 and tries to take off in 6th. stupid stupid DSG.

40km in 6th gear.

You're saying it actually changes *up* gears in S? Gad, never seen that occur.
