The 1.0 Boosterjet (I've got an AllGrip) drives better than the 1.4 Hybrid. Maybe the heavier weight of the 1.4 engine and some small batteries makes the difference but I reckon the suspension is set up better in the 1.0, less dip and roll in the bends. It's a bl**dy brilliant car! Drives more like the original 1.4 Boosterjet S but with a bit less grunt.
