I'd be knackered if one was in my car. It's a boggo 2001 1.6 Astra auto, the old 8valver. Yet it goes like a scalded cat. I blame the drive by wire throtle - it's WAY too sensitive. I have a light foot, but the initial takeoff from rest even gently can easily invoke wheelspin and "push you back in the seat"ism. Cornering G force can also be a bit "whoa", as the gearbox has a liking for downshifts under constant throttle on, say, roundabouts.
I'm quite used to it (it makes me grin a fair bit, the chassis dynamics suit it perfectly), but when the garage up the road have it for MOT, every time they drop it back there's usally a comment of "by christ, this thing goes well, doesn't it..tuned, is it?"
No, it's not. When I show them it's the 8v as opposed to the 16v, and standard they tend to be rather surprised. Given I removed the 1.6 badging as well, they automatically assume I've dropped the 1.8 in it or similar, I think. It does like petrol though..
It's on the emergency map at the moment due to a lambda data issue, but I can't say I've noticed...which is almost worrying. I'm the 2nd owner after motability, so I can't see it being a tweaked setup at all..
