AltWheels Alternative Transportation and Energy Festival relies heavily on Classic in the planning, organization and promotion of its annual three-day alternative transportation festival held in Boston. Presenting alternatives to traditional means of transportation that rely on fossil fuels, AltWheels displays dozens of vehicles with the participation of more than 70 organizations.

In addition, AltWheels features a day-long seminar and diverse panel discussions on clean transportation and alternatives to fossil fuel vehicles. In Classic’s first year, AltWheels brought in its first corporate sponsorship and saw attendance increase by 75% over the previous year. Classic has continued to help AltWheels grow and helped coordinate the event's move to City Hall Plaza in downtown Boston.
