No it's not. The X12XE engine only produces 65bhp. The one in the C is called the Z12XE I think, and produces 10bhp more.
Perhaps someone might want to scan in the engine spec page from their Vauxhall Corsa owner's manual to confirm this?

If the X12XE had 75bhp then there must have been something wrong with it, because my Astra (82bhp C14SE) is about twice as powerful and is only 8v, both cars with auto boxes too! The Corsa I had seemed about as powerful as a 1.4 8v SPI!

My C14SE (with modded airbox and K&N panel filter which adds 956bhp) is miles better than that piece of shit lawnmower engine (X12XE)!
My next engine in the Astra will have 6 cylinders...

Did the late Corsa B have the Z12XE engine then, or a revised X12XE?

OJC's which got rr'd standard at 75 was a X12XE.
Sam how the hell does a auto box work? surely it changes far too early as most users of an auto box won't be ragging it?
If so the sxi only performs if you drive it between 3.5k -> 5kish at all times.

With the GM auto box, you have 3 'modes';
- Winter mode, which no-one ever uses unless you live in Antarctica or something
- Economy mode, which is basically the default setting when you put it into 'Drive'
- Sport mode, same as economy mode, but revs higher before changing gear
You can also use 1st, 2nd, and 3rd gear and (sort of) drive it as if it were a manual...

Getting my car rr'd next sat so I'll know for sure then and finally put a end to the curiousity on what it is!
A fiesta 1.25 is supposedly 75 bhp too - yet I raced one on the m40 and we both topped out at around 117mph on the clocks (106/7 mph) and were basically not getting any further apart.
If there was 10 bhp difference + the fiesta's extra 50cc I think I'd have been left behind!
Paul J
out of interest, was the festa a zetec or the LX model with a zetec lump?

I think the 1.25 16v engine is Zetec.

zetec
and sam, still I'm sure with the auto you can't hang in that gear for a long time...
The reason your 1.4 8v felt so much faster I'm sure is the fact that the 8v has the power low down the rev range. So as soon as you put your foot down the power was there - this of course would suit the auto box perfectly and thus give you the best from the engine.
The 1.2 16v has all its power between 3.5 - 5ish k rpm, any lower and it just won't even move.
Regardless of the fact the auto box has 'sport' mode it wouldn't change at the right revs for the fact that most people who have auto's and 1.2 16vs don't race them.
ok it might of rev'd to say 3.5-4k before changing but then it drops back to 2.5k or whatever and would be out of the power...
Ask people like AdiSri and the people I went to southend with. When my car was running quite well I was able to almost keep up with 1.4 16vs just because my car was in the power when I floored it where there's might of just been a little under.
Most of the people I've driven with / raced have been shocked to find out its a 1.2 16v.
Only problem is its been going like a dead horse for several months - When I took it down the strip it was running crap.
I know a Sxi is never 'fast' but to get the best of it you have to run it in a certain rev range all the time!

this is a misconception. 16V produce their peak torque high up the revrange 8V motors produce theirs low down. 16V motors still have high torque figures 2500-3000rpm it's just that they are lower than peak.

If you use 1st, 2nd, and 3rd gears, you can rev it to the limiter. You cannot do this in 'Drive' or by using Sport mode.
I think my Corsa was just shit - there's a guy off here I raced against at Santa Pod ages ago, he had a 1.0 12v manual, managed to beat me to about 60-ish from what I can remember, although I was slowly going past him after that point as his engine ran out of puff, and mine had 4 cylinders!
He has a 2.0 16v in it now, don't know if you know him, has a private plate 'R17CH U' or something?

yeah it is, but they did a facelift model in 1996 (funny/flat headlights) and another facelift around a T or a V plate (headlights cut into bonnett), and the earlier models seem to have no problems passing the later ones. Must be a wieght advantage I suppose, becos the LX models didnt have PAS or air con
at racing 1.2 lawnmowers, my cars fecked becos or driving it at high revs and heavy breaking. They really aint built for it!!
