Cadillac Lyriq. Ford Mustang Mach E. Polestar 2. New, premium electric cars are coming and they will inevitably be compared to Tesla, the baseline for battery-powered success. But to sell in volume, these challengers must also outperform the gas siblings across the showroom floor. Take the electric Audi e-tron Fastback and Audi SQ5 SUVs I just drove to Hell and back. Hell, Michigan, that is. My favorite southeast Michigan drive route, the 120-mile journey tests a vehicleâs tech, handling and range. The gas-powered, $45,000 Audi Q5 is the brandâs best-selling vehicle, and its SQ5 performance version is the e-tron Sportbackâs peer in power, looks and handling.
