Thanks to technology such as turbocharging and direct injection, today’s four-cylinder engines are more powerful than ever, leading to extremely quick compacts and more frugal large cars. If you have your sights on a four-cylinder vehicle but don’t quite know which one, we've compiled a list of 10 cars with the best four-cylinder engines to help set you straight.
Being best doesn’t necessarily mean making the most power — it could mean being more efficient, better to drive or even smoother. Because this is a list of just cars, we’ve had to ignore some interesting engines that are only available in motorcycles, trucks, minivans, tractors and industrial equipment. Read on to see our choices, sorted in order of cars' horsepower per liter of engine displacement.
