For auto companies, concept vehicles reveal their vision and imaginations for the future. The future could be next year or in 10 years to come. In some cases, these concepts usually have outrageous and unbelievable features as well as specifications but interestingly, there are some working prototypes already. We've seen some concepts come to reality such as the recently revealed Audi E-Tron GT concept which Engadget made a review of.

Often, concepts remain in the development phase for a long time and never go into commercial production until the projected time is right. Before now, design, architecture build, and level of sophistication were the focus for concepts. Today, it's a lot more different. More attention is paid to autonomy, energy use, aerodynamics, comfort, reliability, and efficiency. Most concept cars of today are electric and incorporated with self-driving technology. Already, the autonomous technology is in use but still undergoing perfection. An example is the Tesla AutoPilot.
Some auto companies like Toyota have even gone the extra mile to build concepts that perform more than just transportation. There are now concepts that serve the function of food deliveries, sales, luxury chauffeur service, and the list goes on.
These concepts span between sedans and SUVs and well, minivans and crossovers. In no particular order, here are the top and most inspiring concepts revealed in 2018.
