Prepare for the return of one of the most iconic performance Mustang nameplates ever. Ford is bringing back the Shelby name in the form of the GT350 Mustang. It boasts a new 5.2-liter engine and the first-ever flat-plane production V8 from Ford, which provides more than 500 horsepower, with a torque peak above 400 lb.-ft. It's the most powerful naturally aspirated Ford production engine ever, and it all comes in the form of a muscle car that looks both classic and modern. Another beast in the new line of Mustangs celebrating the car's 50th anniversary.
