Sportback is the 5 door version I believe.

DSG definitely not automatic in the conventional sense, although looks/drives in a similar way, and can change gear automatically, so technically an automatic I suppose.

its the DSG gearbox thats the key talking point with this model. Jump in and youre greeted with what looks like a relatively conventional automatic gear lever sprouting from the transmission tunnel.

Closer inspection reveals that the gearstick can be knocked sideways into a slot so that you can push it forward to change up a gear and pull it back to drop down a ratio. There are also paddle shifters behind the steering wheel to achieve the same effect. But then a number of cars already feature such a system. Whats the advance? Its important to understand how these other cars gearboxes work.

Basically, they can be split into two forms. The first is a proper automatic gearbox that can double up as a rather poor manual box as typified by Porsches Tiptronic system, and the second is a sequential manual box that will, at a pinch, function as a somewhat clonky automatic as typified by Alfa Romeos Selespeed, Ferraris F1 or BMWs SMG system. Neither system is ideal. Tiptronic style gearboxes use a torque converter and as such are inefficient and a touch slow witted albeit very smooth.

The sequential manual gearboxes can be brutally efficient in manual mode but are neither smooth nor very convincing when trying to mimic an automatic gearbox. Just try a hill start in reverse and youll see what we mean. Audi have approached the issue in an ingenious way. The TT 3.

2 V6 uses a sequential manual gearbox in order to ensure efficiency and rapid responses, but it also uses a clever twin clutch system to ensure creamy smoothness. Engage first gear and the gearbox will pre-engage second gear in advance, the second clutch engaging as soon as you flick up to fire the TT instantly into second gear. This means a seamless flow of power. The electronics predict what gear youre about to engage, depending on whether youre accelerating or braking and the result is astonishing, making every other gearbox look distinctly clunky.

The other option is to slip it into D and drive it like a normal automatic. Even in this mode its butter smooth. One comes away with the impression that Audi have a tangible advantage over everybody else with this system and that some day all gearboxes will be made this way. The car is available as a manual but most buyers really should find the £1,400 to get the DSG.

Function in detail

Conventional manual gearboxes operate with just one clutch. To change gear, the driver steps on the clutch pedal and interrupts the power flow. This is a prerequisite because when changing gear a different pair of gears (ratios) is selected in the gearbox - and this cannot take place under load.

The DSG ® Direct-Shift Gearbox prevents this power interruption. In idealized terms, it offers the function of two manual gearboxes in one. Its technology though is combined in a single compact component.

Unlike conventional manual gearboxes, the Direct-Shift Gearbox has a two-part transmission shaft comprising an outer hollow shaft and an inner shaft. The inner transmission shaft serves the 1st , 3rd and 5th gears, the outer shaft is for gears 2, 4 and 6. A twin multi-plate clutch transfers engine power permanently to one of the two shafts.

When driving, one gear is always engaged and a second pre-selected. When the gearshift point is reached, one clutch segment opens in a flash while the other closes. The driver therefore hardly notices the gearshift process. This uninterrupted, efficient transfer of power enables particularly sporty driving.

Paddleshifting 3.2 has gone back to ST, TT is having new wiring thing put in and mad mouse loose ashtray fixed, won't be ready til tomorrow, so tomorrow I am off to Sheffield in an A4 B7 something that sounds dieselesque but its dark and I haven't looked at the badge. I am obviously meant to drive every car Listers have on their stock list. pengy.gif

Quite liked the DSG, although had strong temptation to push brake pedal with left foot in attempt to drop clutch at junctions. Disconcerting. ROLLEY~14.GIF

Is it a B7 2.0TDI S-Line? smlove2.gif

Its all of those things apart from s-line. Its quite nice though actually for a soot chucker!! wink.gifgrin.gif It has a little fridge to put your beer in in the glove box, parking sensors (a novelty for me), automatic wiper things and goes quite fast when you floor it. Cough. Thats the M1 sooted up for the day. jump.gif

Right, now where is my QS..... coffee.gif

Really - drive it harder and it gets faster?! I heard if you drive like a girl (!!) it can reset the throttle or something to less power. So what, I should floor it at every available opportunity even in Sainsburys car park and it will be a demon of a machine.... 169144-ok.gif

How is new Boxster?!! jump.gif
