Owned by Daimler, a Smart car may be the cheapest way to get in to a Mercedes-Benz family member, and may be the most efficient too. The company has inexpensive tiny cars aimed at Europe’s tight roads and parking spaces, and its non-hybrids get mpg in the 30s and it also makes an electric Smart. Rated at 119 MPGe, it is an efficient car for those who can get it.
