* Drive Type: Front-wheel drive Impalas will struggle more in snow than all-wheel drive (AWD) vehicles. AWD Impalas will generally handle snow better, offering improved traction and stability. Rear-wheel drive Impalas are generally *not* recommended for snowy conditions.
* Tires: Winter tires are crucial for any car in snow, regardless of drive type. All-season tires may suffice for light snow, but winter tires dramatically improve traction and braking in icy or snowy conditions.
* Driver Skill: Even the best vehicle will struggle if the driver isn't experienced in handling slippery conditions.
* Specific Impala Model & Year: There can be slight variations in handling characteristics between different model years and trims of the Impala.
In short: A front-wheel drive Impala with all-season tires will be challenging in significant snow. An AWD Impala with winter tires will be significantly better, but still not as capable as a dedicated SUV or truck with AWD and winter tires. A rear-wheel drive Impala is strongly discouraged in snowy conditions.
