Hi

I am considering to sell My 2014 1.4 103kw fr manual and order a new st fr but having some doubts whether the 1.8 is the engine to go for .1.8 dsg is 1k eur cheaper than 1.4 110kw act dsg .Has anybody gone from a 1.4 to a 1.8? What are your thoughts. 1.4 dsg or 1.8 dsg? Fuel consumption would go up a bit, 1L per 100km and it would take around 50k km to break even the price difference between 1.4 and 1.8

Another thing, anybody has a clue when could we expect leon MK4? Looking back to mk 1 2 and 3 intervals, the mk4 shouldn’t come before 2019.

Are you serious?
1.4tsi is so much less of a car than 1.8tsi.
There is some much more grunt and smoothness with 1.8tsi and also better brakes, better suspension, better value, better possibility to tune it.

Lucky guy if 1.8dsg is 1k cheaper!
In my country, 1.8dsg is 2k expensive as 1.4 act dsg and 2.0tdi dsg (184k) is another 2.5k expensive as 1.8dsg....

I am currently thinking of changing my 3y old 1.4 act st fr act manual for 1.8tsi/2.0tdi dsg or man. Found out, that dsg for tsi is BAD choice - DQ200, dry system. Nobody recommends it from the long term perspective.

So thinking only about 1.8 man or 2.0tdi dsg. And even 1.8 man I am not sure if it is worth 2k more as 1.4 act man..
1.8 has the same torque 250Nm as 1.4 act, no change. HP is better, but what for? My consumption on 1.4act is 6.6l/100km, on 1.8 it will be for sure 8.5l/100km. When thinking about 2.0tdi, it is possible to reach 5.5-6l/100km, which makes more sense....

So think more about DSG.
If 1.8 is cheaper (are you sure? not more expensive?), then nothing to think about....

1.8tsi dsg st fr is 21990.- eur and 1.4tsi dsg st fr 22990.- - official dealer prices.
8.5 per 100 km seems to be a bit too much, it should be around 7,5to 8 as an average. But it always depends on many factors...
Well about the dsg - as long as its lasts for 200k km it should be fine as i am not planning to have this car forever- 5-7 years max. When reading about the problems they seem to have solved some of the problems by replacing synthetic oil to mineral and for the 1.8 we only have the 7 speed dsg available.

Thanks for the answers and opinions so far

In my country, prices are as follows:
ST FR 1.4 ACT 6man - 20.340 Eur
ST FR 1.4 ACT 7DSG - 22.410 Eur
ST FR 1.8 6man - 21.540 Eur
ST FR 1.8 7DSG - 24.110 Eur
ST FR 2.0 TDI 6man (110kW) - 22.390 Eur
ST FR 2.0 TDI 6DSG (110kW) - 24.190 Eur
ST FR 2.0 TDI 6man (135kW) - 24.150 Eur
ST FR 2.0 TDI 6DSG (135kW) - 26.720 Eur
As you can see, this is more difficult to decide.
I am not interested in TDI manual versions, as my experiences with TDI are that shifting is too "heavy" and "slow". I am not buying truck... So if TDI, then only DSG version.

Coming back to TSI versions - 1.8 has from my point of view just one benefit - rear suspension. Otherwise we have to speak about disadvantages - higher tax, higher consumption, higher pricing. Consumption is really high, check this link. Average is around 8,0-8.5l/100km.
1.4 ACT version has the same torque and has enough power for any daily life (my last 3y experience as I have this version). Basically I did not notice any bad experience with rear suspension in 1.4 ACT version.

If you have such pricing for 1.8, then f**k the consumption and go for it! :)
In my case, the pricing is higher and have to think about other negatives of 1.8. So not sure if it makes sense to go in 1.8.

The power gain from 1.4 to the 1.8 will be more than noticeable. It pulls very well all the way through the rev range. (It sounds much better too)

I get about 35mpg driving with a heavy foot in sport mode. 40mpg if i drive 'normally'. (on a 1.8 TSI DSG)

the 1.4 tsi150 is a little cracker.had it in my previous golf.
the 1.4 and 1.8 have same torque output (250nm)
the 1.8 is probably a bit stronger higher in the rev range than the 1.4 and probably sounds a bit more sporty when pushed but don't think the 2 engines are a million miles apart.
I currently have the tdi 184 engine and to be honest whilst just dotting around the 1.4 just felt as sprightly.
really disagree about the 1.4 is much less of a car than the 1.8 tho.
a little bit harsh imho!!!
the 1.4 will quite happily get up to speed with no hassle.

I have had the 1.8Tsi for 2 weeks now and I love it, my wife has the 1.4 EcoTsi in her Audi A3, whilst of course the cars are different and the Audi is a bit heavier I don't think there is a vast difference but there def is a difference, despite the same torque levels the 1.8 does "feel" more responsive for me and as someone has already said, with the 1.8 you get the "proper" rear suspension :D

Having said all that, if I was concerned about fuel costs and/or did 10,000+ miles per year I would have no hesitation going for the 1.4, I took the 1.8 because I do less than 5k miles and I didn't want to wait an extra 2 months to get the car, personally I don't regret the decision.

In reality 1.8 tsi has way more than 250nm.
Also check the offical tech sheet what is the torq range on 1.8 tsi vs 1.4 tsi.

And not just the motor, the suspension on 1.8 tsi is a way much better also.
Drive both and you will feel the difference for sure.

Anyone saying there is not much difference did not have the cash to buy 1.8tsi so they lie to their self everyday and others too so they would not feel so poor about having 1.4:cry:

I went from the 1.4 to a GTI. I would still recommend the 1.4 over the 1.8 as it's a much better all-rounder. Of course if money were literally no object then the 1.8 is slightly faster.

I do wish I had more power in mine but that's just me and for the money a remap will get it up to the same sort of power as the 1.8 at a fraction of the overall cost.

As I got mine through a broker, I only paid £400 more for the 1.8 so I consider I paid nothing more for the engine and the 400 covered the proper multilink rear suspension :bleh:

Fair play. Think it was considerably more when I looked and got mine but my insurance, tax and mpg were also added into the equation for me too.

I have to say, I am still quite impressed with the handling of my 1.4 despite not have the multi link read end. That's only for moderately quick road use though, nothing silly or track runs or anything.

I’ve no idea about the MkIV but if the 1.8 TSI is now retailing for less than the 1.4 EcoTSI in some territories then perhaps SEAT are clearing out their stock of that engine... so they can replace it with the newer 2.0 TSI 190PS which is found in the Ateca, paired with the DQ381 7 speed DSG that can handle the 320Nm of torque.

In A3 S Line trim the 2.0 TFSI is not only slightly more economical than the old 1.8 TSFI but the extra 70Nm of torque means it’s almost half a second quicker to 62mph [B)]

A3 S Line:
2.0 TFSI with 190PS & 320Nm (50mpg) 6.8secs [151mph]
1.5 TFSI with 150PS & 250Nm (57mpg) 8.2secs [136mph]
1.0 TFSI with 115PS & 200Nm (63mpg) 9.9secs [128mph]

Leon FR:
1.8 TSI with 180PS & 250Nm (49mpg) 7.2secs [139mph]
1.4 EcoTSI with 150PS & 250Nm (58mpg) 8.0secs [136mph]
1.0 Ecomotive with 115PS & 200Nm (64mpg) 10.0secs [126mph)

Ateca:
2.0 TSI 4DRIVE with 190PS & 320Nm (40mpg) 7.9secs [132mph]
1.4 EcoTSI with 150PS & 250Nm (51mpg) 8.6secs [123mph]
1.0 Ecomotive with 115PS & 200Nm (54mpg) 11.0secs [114mph]

In my country (Bulgaria), the 1.8 TSI is 500 quid cheaper than the 1.4 ACT in FR trim, so that is why I ordered the 1.8 TSI. I think that will be the last 1.8 TSIs and they will be switching to 2.0 190 PS as you said because it makes more sense in the line-up: 1.4 TSI ACT 150 and 2.0 TSI 190...I am pretty sure when the new 2.0 TSI comes, it will be much more expensive than the outgoing 1.8 though. Actually, the new 2.0 TSI in the Ateca is 500 quid more expensive than the 2.0 TDI 190 and 1 500 quid more than the 1.4 TSI Ateca in FR trim. Simple logic, the 2.0 TSI will be around 2000 quid more expensive than the outgoing 1.8 TSI. So, I think the 1.8 TSI is a very good bargain now.

If 1.4 TSI wasn't more expensive than the 1.8 and with inferior rear suspension, I'd go for the more economical and practical engine. Yes, the 1.8 TSI is a beast compared but in 95% of the time the 1.4 will be just as good and way more economical. The 1.4 TSI is the more modern engine, no doubt, but for the price that the 1.8 sells now, it's a no brainer!
