This type of bus also performs better in snowy or icy conditions, as the thrust from the driving wheels does not cause the vehicle to jacknife. Newer models such as the Van Hool AG300 feature low floor while maintaining the puller design placing the engine block off-center opposite to the second door. Also, the unpowered rear axle is much simpler and carries no engine weight, facilitating the installation of counter-steering mechanisms to further decrease the turning radius.[citation needed]
