What are the differences between the Audi A1 models?

I'm interested in purchasing an Audi A1, but I'm confused about the various model options. Can someone explain the differences between the A1, A1 Sportback, and A1 Citycarver?

The A1 is the base model and the most affordable option. The A1 Sportback has a slightly longer wheelbase and more storage space. The A1 Citycarver has a raised suspension and rugged exterior design, perfect for city driving.

In terms of trim levels, the A1 comes in SE, Sport, and S Line options. The A1 Sportback is available in more trim levels including Sport, S Line, and Vorsprung. The A1 Citycarver only comes in S Line trim.

The A1 and A1 Sportback are available with a choice of petrol or diesel engines. The A1 Citycarver only comes with a petrol engine. It's important to consider your driving needs and preferences before choosing a model.
