Fiat Tipo engine.
The 1.6 engine is a punchy performer, with enough torque at low enough down the rev range, and a nice sound with a burble when the throttle is lifted.
However the gears aren't too good for motorway driving, with approx 3200rpm at 70ish, which is quite loud. Saying that though, the engine is at max power at 6000....so Fiat clearly made the engine enjoy being worked hard.
This engine bay was absolutely filthy when I first looked at it, it took a whole can of Jizer to get it to this.
