DSG vs Manual

I just got the new sportback with dsg box. It is a vast improvement :) ill never go back . Luckily I've also got paddles for when I want to be a hooligan

The problem is people equate it with an automatic gearbox. It is not. I drove an auto Toyota the other day and it was horrible coming from my A5. The gears don't change at the right time, it's clumsy and bumpy and really chalk and cheese.

Yeah I wish people would realise it's a manual gearbox with an electronic clutch and not an old fashioned automatic.

Wouldn't describe it that way, in practice most people use them in full-auto mode majority of the time. I certainly do.

Technically DSG use 2 independent auto gearboxes/clutches (with alternate ratios) where the drive gear is changed be flipping the clutches (that why its so fast). Mechanical gear selection is done in the background by a processor (on the unused box) , constantly predicting whether the next ratio should be the one above or below (based on prevailing driving conditions).

There is a very big difference between a traditional auto gearbox and a DSG gearbox. An auto-box has a torque convertor. This accounts for the increased fuel consumption and feelings of lag. The DSG box has clutches which are the same mechanism as a manual gearbox's clutch.

Sure, I was referring to 'auto' from the driver's perspective i.e. it can change gears on its own without input.

Sure. But the driving experience is nothing like the same :)

I'd disagree, my DSG reacts faster then I would be able to most of the time.

Nothing like 'taking the gap' with a DSG in auto, you dont have to think where you're in the right gear or whether you should/can change to the one below fast enough. As soon as you see the it, just hit the gas for instant/lag free acceleration.

DSG changes gear faster than any human is physically able to.

It was either 60 or 600ms from what I remember.

However that's that actual gear change action hitting the paddle, not including the time it would take to think about it when in auto mode.

Yup I know exactly how it works.

Point was, as was already said above its pretty much still two manual gearboxes with electronically controlled clutches and actions.

Very very different from a conventional auto box and in fact closer in mechanical operation to a regular manual.

Is it true that some GTi have different spec DSG boxes to handle more torque?

I think the 6 speed wetclutch and 7 speed dryclutch have different torque capabilities.

Agreed, just the way you articulated your original statement seemed confusing, implying clutch-less but still manual gear change (to me).

Oh ok, thought you meant driving your DSG manually (with paddles) was a more satisfying experience then just letting the box do its thing (automatically).
