someone from my work just purchased a 1.4T Astra GTC, he let me take it for a spin :p

I was just wondering if the engine would be the same that goes into the corsa because the engine and the 6 speed gearbox were incredible!

Yes same engine and gearbox but engine is running the 140 or 150PS map (can't remember which) not the 100PS as found in most Corsa E's. Red and black edition Corsa E's have the 150PS 1.4T though :)

Oddly enough I fell in ❤ with the 1.4T after I test drove an Astra with one fitted. I knew if it could shift a heavy Astra it would work well in a Corsa.

It's a lovely engine, lot of power and with that silky smooth gearbox I know what I'm getting next!

I was so surprised at the difference between the 5 & 6 speed gearbox though

The 6 speed box is fantastic. I've done 12K miles in my 1.4T 6 speed LE and achieved great mpg and it cruises lovely on the motorway.

What is odd is the widely differing official performance figures for the Vauxhall cars fitted with the 1.4T engine:

2015 Corsa 1.4T 100PS (200Nm), Kerbweight approx 1200Kg, 0-60=11 seconds
2016 Corsa 1.4T 150PS (220Nm), Kerbweight approx 1200Kg, 0-60=8.9 seconds
2014 Astra 1.4T 140PS (200Nm), Kerbweight approx 1500Kg, 0-60=9.0 seconds
2016 Astra 1.4T 150PS (235Nm), Kerbweight approx 1300Kg, 0-60=7.8 seconds
2015 Adam 1.4T 150PS (220Nm), Kerbweight approx 1150Kg, 0-60=8.5 seconds

How on earth can the old Astra which weighed 300Kg heavier than the Corsa have an almost identical 0-60 to the 150PS Corsa?

The 1.4T 100PS is shown as 11 seconds 0-60 which quite frankly is ridiculous as I've managed it in under 9.5 seconds. I suspect they are understating the performance of the 1.4T Corsa in order to sell the VXR's or to keep insurance bands low???? I can't see that the gearing is all that different between the three models?

It is very odd. I'm going to have my 1.4T mapped next year to 150-160PS and I'll get a 0-60 time recorded properly. I just don't understand the official figures as they don't seem to make sense. Either the Astra time is too low or the Corsa too high. Or The engines are not actually the same?? While I'm not so much interested in doing 0-60 I do find it curious why the figures are so varying and why seemingly heavier cars are showing far lower official figures.

Yeah I don't believe that stats they give are accurate at all, but I suppose the 0-60 times are without them putting their foot down loads?

My 1.2 Sri has a 0-60 time of something like 16 seconds :lol: I've done it abit quicker than that but obviously was accelerating quite hard

No complaints from me. My 1.4T SRi Corsa is superb, The engine & 6 spd box is the best i've had in VX. I've nearly hit 4000 miles and this motor continues to put a smile on my face.

Can't wait to get mine later this week! Looking forward to feeling the turbo kicking in as I didn't experience it during my test drives.

OK, I have discovered that the 1.4 turbo 150PS in the new 2016MY Astra is NOT the same as the 1.4T we have in our Corsa E (not even the 150PS Red/Black editions). It is a brand new engine with direct injection and all alloy block.

The old Astra (upto 2015) did have the same 1.4T as we have.

It seems the new 1.4T SIDI engine has even more torque, upto 245Nm (below 3000rpm too) which means it virtually matches the torque produced by the current 1.6T Corsa VXR! It also has even better mpg than our current 1.4T and it is lighter than our 1.4T which means even better power to weight ratio.

This new engine should be fitted in the Corsa within a couple of years as I gather it will be replacing the old 1.4T in all future Opels. Sounds like it will be an impressive little engine! :cool:

So potentially the Astra GTC i drove could of had the newer engine in?

Can't wait to get a few years driving experience and get one of these engines
