    whys my 1.8 coupe faster then other 1.8s?

    hi i have the 1.8 coupe and i have a mate whos got a 1.8 16v astra hatchback and have raced others with 1.8 astra hatchbacks, and i always seem to pull ahead is this purely because the coupe is abit lighter? i have done it with a large passenger against someone with no passenger :S was just wondering thanks

    Wait till Ffoeg sees that.


    Couple of factors as to why yours is "faster" ...

    1: You're a faster (not necessarily better) driver.

    2: Yours was driven harder/faster from new meaning the engine is a bit more loose but might not last as many miles as the guys engine in the hatchback.

    3: Drag coefficiency of the coupe is lower (better) so at higher speeds (130mph+) it will make a small difference.

    4: You have fatter wheels & tyres to get better grip on launch.

    5: You possibly have some modifications and the hatchbacks you "raced" don't?

    Gearbox ratios?
    Tell me what you've done, not what you're going to!

    1.8 Coupe & Hatch share the gearbox raios dont they? as do the 2.2 Hatch & 2.2 Coupe, Coupe Turbo & GSI etc.

    thanks for info hopefully not down to the driven harder/faster from new as it only had one previous owner which was a woman, its standard too apart from springs must be down to driving and the drag thanks

    Your Coupe is faster than the 1.8 hatch as yours has the close-ratio gearbox and the hatch does not. It shaves about a second off the 0-60 time.

    My mate used to have a 1.8 SRi G hatch and it did not have the close-ratio box, which surprised me. His Corsa 1.8 does have it however.

    The 2.2 & Turbo's share the gearbox but have different gear ratios.
