    Comparison 1.4 TFSI COD VS. 1.8 TFSI

    I drove the 1.8 TFSI but wonder how the 1.4 TFSI COD compares as both cars have the same torque of 250 Nm. Anybody drove both cars ? Fuel consumption on the COD must be much better but what about sheer fun ?

    Thanks

    Does the 1.4 cod really have the same torque figures as the 1.8 tfsi?

    Hi, yes it does if you are talking about the 140ps version, the 1.8 will have better out and out performance but whether this will be noticeable under normal motoring I wouldn't be so sure and the 1.4 will be cheaper to run. 2013 Audi A3 Saloon 1.8 TFSI review and pictures | evo

    Ahh okay this is nice to know as I have ordered the 1.4 cod hence my question. How about you, what are you driving or planing to buy?

    In the mean time I could extensively compare both the 1.8 TFSI and a 1.4 TFSI CoD.

    I was pleasantly surprised by the CoD engine. It was so much fun driving and in comparison with the 1.8 TFSI it felt less raw. Sure at top speed you will miss some power in the CoD but at the end it is for me much more fun to drive more economically so I chose the 1.4 CoD

    Top speed these days are irrelevant, there are speed cameras everywhere.

    Went for the 1.4 CoD on my order after reading much praise in reviews. By all accounts it's just as "fizzy" as the 1.8 for everyday driving. My current car is 95bhp so i thought it would be enough of an improvement for me in terms of enjoyment and power.

    I think they seem to be like two totally different engines. I've got the 1.4 CoD (which is great by the way!) but seeing the 1.8 perform on youtube it seems to be quite happy producing power from 4k-6k RPM.

    The 1.4 CoD is more 'diesel' like in its power delivery i.e. it produced quite a bit of mid range torque (which is great for every day driving). There isn't really much more from 5k-6k rpm.

    Here's a video showing the 1.8 2013 Audi A3 1.8 TFSI 180 NICE! OnBoard - YouTube

    It seems to me the 1.8 is a more 'sporty' engine than the 1.4 CoD.

    That being said the 1.4 CoD is pretty flexible, it'll still pull in 6th gear (manual) from 40 MPH upwards. Makes motorway driving a breeze!

    Hi guys have any of you got the s-tronic car. If so how's it like to drive I have heard reports of the gearbox being quoted as "disappointingly jerky", is this true? These are the words of WHAT AR

    Never driven the COD but I have the 1.8T S-Tronic and it does just continue to pull at higher revs. In fact that's where it really comes alive. With the soundproofing you really can't hear that it's revving up that high.

    Thanks for video link - will check it out when I have better mobile reception.

    I also have the 1.8 S-Tronic and it is a beautiful engine it is really refined with a nice smooth power delivery, my old Subaru had noticeable turbo lag, it was flat until the turbo kicked in around 2500-3000 rpm then it flew. This is nothing like that! Silky smooth power delivery right up to the redline

    It is smooth an civilised if the S-Tronic is left in Drive, pop it into Sport or drive select into Dynamic and it really livens up. It's a quiet engine but in the higher rev range at has a lovely rasp to the exhaust note make you want to push on
    Not felt any torque steer either, that surprised me :D

    The only downside is if your not used to the characteristics of the S-Tronic 1.8 you may notice a slight "lag" pulling out at a junction due to how early the car changes from 1st into 2nd, but pop it into Sport at tight junctions or roundabouts and this will cure it

    All this said I have not driven a COD so can't comment on that set up. Reading the reports on here the COD is more efficient if that is what your after, but for me the fun is in the drive and get around 25mpg in town and 45-50 on a run.

    Hope this helps

    P.S sorry as for the gearbox, if left in Drive it is smooth as silk, but pop it into Sport and you can feel the down changes as you would expect along with a nice little blip of the throttle

    I watched this video so many times while waiting for the car lol but the dude is changing gear with the paddles and his gear changes are all over the place? I think most of us would be a little smoother than that, if not just leave in the auto

    its a good review and seams balanced, but still praises the C.O.D. And the A3 in general, nothing new but seams a bit more thought out. lots of reviews just written on what they expect to find and following everyone else's opinion. In some reviews you wonder if they have even driven the car they are writing about or just plagiarising what they have read some where.

    Johnny and 97cata sum the 1.8 up totally
    A little jerky in different drive select modes and sometimes around town dependant on situation. Remember the car can't see the road so will change gear on revs. With a manual you choose thus meaning if traffic only moved a few feet you on the manual would stay in 1 gear. The S Tronic at this point could have jumped 2 gears. Driving the S Tronic I'm sure you can appreciate what I'm saying.
    Again the car really does keep pulling! It's not neck snapping by any stretch but once in the higher revs it is a smile maker oh and the exhaust rasp is cool too

    I believe that the exhaust note, or tone, is actually produced by some kind of 'sound box' equivalent to the 'symposer' that is fitted to my engine. It uses the induction side of the engine to make that 'rasp', or 'zing'.

    Yes, with the box in Drive and Drive select in comfort, auto, or Eco the changes are very smooth, almost in noticeable. But Dynamic with the Box in Sport you can feel them, and to be honest I would be disappointed if it was any different, because that's the idea!

    This is the reason why we have drive select, Eco is attempting to give you the most fuel economy making the throttle response slower, changing gear at the most economic time, and giving you "Coasting" when power is not needed.
    Comfort gives you slower gear changes to smooth out the change, average throttle response, and engine braking.
    Dynamic throws economy and comfort out of the window giving you the best performance, quicker gear changes, snappier throttle response, revs are held longer, throttle blips on the down change to match engine revs, this is all because it's expecting you to be driving it like you stole it

    In dynamic driving it hard the up changes are still smooth and the power delivery is very linear, so the sensation of acceleration is not as dramatic as a manual because the jerkyness of changing gear is not there even though you are just as quick.

    My cousin recently took me out in his Bentley Continental GT Speed 600+ BHP W12, mega fast with an S-Tronic style gearbox, the characteristics of the box are exactly the same, even the same layout with the weird back to front + and - when changing manually with the stick. Obviously a VAG thing

    Do both have the 7-speed S-tronic or is the 1.8 TFSI the 6-speed wet clutch variant? I know the quattro is definitely 6-speed.

    Both have the 7-speed dry-clutch s-tronic. Only the 2.0TDI-150 and the 1.8TFSI quattro and 2.0TDI-184 quattro models have the 6-speed s-tronic. I'm on my fourth 2.0TDI and all four have had the 6-speed s-tronic and they are brilliant. My wife had a test drive a couple of years ago in a Polo with the 7-speed and she did say it was not a nice to use as the 6-speed in my A3.

    Thanks. The inconsistencies and errors in Audi's used car listings are unbelievable - so many of these have said 6-speed on a 1.8 (non-quattro)! I drive a 1.2 TSI DSG 7-speed right now and I'm happy with the box, aside from wheelspin on fast launches.
