Porsche is the latest automaker to unveil a Vision Gran Turismo concept. Porsche's concept is an electric sports car, and while it isn't bound for production it may provide clues toward the design of the automaker's future lineup.

The redesigned 2023 Nissan Z sports car is the basis of the Japanese automaker's next Super GT GT500 racer. Nissan has revealed the new Z GT500 and it looks absolutely wild thanks to its all-carbon, wide-body design.

We tested numerous new cars over the course of 2021, Covid-19 restrictions notwithstanding. As is the case every year, we'll decide the best of the pack and award it the Motor Authority Best Car to Buy award. Find out this year's finalists in the links below.
