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.
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!
