1.4 FR is incredible but.....

I'm betting the 1.5 EVO TSI will be available in the Leon soon if your willing to wait a bit...

ACT 'just works'!!

I've had two 1.4 ACT cars (Leon) and have been faultless.

1.8 TSI better sound in higher RPMs and torque availiable in higher range. But fuel consumption is like in Cupra.

I dont like manual gearbox in 1.4 125KM - smooth change from 1 to 2 is very difficult. 1.8 TSI gearbox is smoother for me.

I had test drive with Ibiza FR 1.5 TSI Evo and ACT running very smooth. It is good engine but probably have GPF (like DPF in diesel)

I don't think there is GPF in the Ibiza 1.5 TSI as there is no mention of it in the manual.

I have the 1.4 ACT 150 bhp and can honestly say it's been one of the best engines i've ever had. Referring to the 1.8 tsi i believe both engines have the same torque so there is not a lot in it when it comes to performance. I'd go for the 1.4 as it's better value IMO

1.4 been faultless for me in the year and 18k that I've put on it already. Act works perfectly and really boosts fuel economy
There's a very subtle change in engine volume when it kicks in and a very slight kick when it disengages so overall very comfortable.

Off topic slighly, does anyone know why act isn't installed on the 1.8 and 2.0l engines? Just because you want 300 horses in a cupra doesn't necessarily mean a little better mpg isn't desirable.

my guess,

it wont be a major selling point for the 2l engines. Buying a GTI, cupra, etc you are buying those cars for performance not economy. Same reason you don't get a bluemotion GTi.

Also, it's new tech. They'll be testing it out on 1 engine first. Remember the twin charged 1.4 being the future, engine of the year, etc? See how that turned out.

It's more to do with emissions than fuel economy, the difference between the 1.4 act and the older 1.4 non act in terms of actual fuel consumption is negligible

My understanding is that the 1.5TSi brings very little in terms of performance and economy, in fact some have said slightly less in the performance stakes, it's just a little more efficient as it has slightly improved emissions.

I have the 1.8Tsi and love it but I would def go for the 1.4 EcoTsi if I was doing any kind of mileage because for me it is such a good balance between performance and economy. Comparing the torque of the 2 engines is to some degree a little pointless, on the 1.8 the torque is available much higher up the rev range so you get that pull for much longer where the 1.4 would flat out earlier, obviously you also get the improved suspension and brakes with the 1.8 too...... or you did.

The 1.5 TSI has a variable-geometry turbocharger which is normally something seen on much more expensive petrol cars like a Porsche 911. It also heats up faster than the old 1.4 TSI, so there are plenty of other benefits to having the new engine.

I am not denying that, however in practical terms, if you see little benefit in performance or economy then apart from a possible price hike, then for the average driver it does not mean a great deal.

Yeah true however I love the idea of the cupra st for my next car in a year or 2s time. I'd love the extra power but given I do circa 20k a year the fuel bills will be astronomical. If act was employed and even raised the overall average by a few mpg to close the gap between the 1.4 and 2l that would make a big difference to the probability of getting one.

Was just curious and trying to justify it to myself lol

ah, the good old 'the lesser car is better than the better one' argument

these have been going on since the beginning of time.

showing my age here, but when i was a lad it was folk claiming their Fiesta 1.4S was just as fast as the XR2.

Depends on what is indicated by better.
the 1.8 is probably more tunable and has some torque locked away which a remap might unlock

1.4tsi/1.5tsi are much closer to compare for 1.2tsi/1.0tsi than to 1.8tsi what is much closer to Cupra than 1.4/1.5tsi cars.

1.8tsi manual has more torq than on the tech specs states, reality is ~280-300nm.
(Due the crappy DSG the torque is limited, but since the DSG is extra option, VAG dont want you to know that the cheaper manual model has more power than the DSG)

1.8tsi gives you not only multilink rear suspension,
but also better front suspension, with 55mm strut and lighter knuckle and bigger bearings.
And you can sure tell the difference, those small engine cars with the low cost cart axle do bounce around when the surface is not so smooth, sharp bumps especially makes them bounce and also when pushing it on a nice b-roads its just doesnt turn in so nicely, its lacks the chassis control that the 1.8tsi, 184tdi and the cupras have.

And also the better brakes, but to be honest, i think the ones on small engines are enough for the performance that the cars deliver.

About the 1.4tsi...it has quite short gearing and as it might give you the illusion of eager engine, dont just look the rev dial, its the speedo dial that matters.
But dont get me wrong...good engines for what it has been design...ECONOMIC, not performance as a key.

Oh and for example...APR map 1.8tsi is ~260ps /400nm+ and fuel consumption dropped 1litre/100km

I have been very happy for mine and i drive 25-30k in kilometres per year.

Half way down confirms its coming to Leon FR at Geneva.

Based on time of year... Expect a MY19 launch?

After 18 months of driving various Ateca I fancied a change this afternoon when I finished work, so I took our newly-registered Leon 1.4 EcoTSI 150 home...

I'd forgotten just how much fun they are! So responsive, even with only double-figure mileage, and feels so much quicker than my Ateca with the same engine. For the first time in as long as I can remember I actually just went for a drive after dinner, testing out the handling on some of my favourite Cornish roads
