Alpina manufactures one basic dual-track snowmobile design. In 2002 the ''Sherpa'' was introduced and is the model name for the four-stroke machine. Prior to introducing the Sherpa, Alpina offered a two-stroke series designated the ''Superclass''. The four-stroke Sherpa is currently the top machine in production. A new version of the Superclass has been released in 2017, with a lot of innovations and a new four-stroke engine. The ''Sherpa'' and ''Superclass'' series shared the same basic dual-track platform, twin {{convert|20|x|156|in|mm|abbr=on}} tracks with dual skis up front. Power for the Sherpa is supplied by a 1.6L in-line four-cylinder gasoline automotive engine. The new Superclass power is provided by a 1.2L 3-cylinder four-stroke gasoline engine. The ''Sherpa'' and ''Superclass'' are designed as working snowmobiles for carrying supplies, pulling cargo sleds, pulling trail grooming implements, carrying several passengers, and negotiating deep snow. Engine and transmission combination are designed to deliver optimum power to pull or carry large loads while top-end speeds are kept below {{Convert|52|mi/h|km/h|abbr=on}}, depending on the model. The large footprint of the dual tracks and dual skis allows the ''Sherpa'' and ''Superclass'' to "float" on top of deep snow and not sink in and get stuck.
