The new model will undoubtedly be more fuel efficient than today's car. Like with the current Fiesta, expect a range of three- and four-cylinder engines that come both naturally aspirated and turbocharged. Don't be surprised if Ford puts more emphasis on the 1.0-liter EcoBoost turbocharged inline three-cylinder in order to boost fuel economy numbers.
While we will likely see the final production version of Ford's smallest US model next week, don't expect the subcompact to go on sale before the 2018 model year. It should hit showrooms about the same time as the recently revealed and closely related Ford EcoSport compact crossover. Unless fuel prices start to rise in the next year and the market shifts back towards smaller and less thirsty vehicles, the new Fiesta will likely have a difficult time finding a large audience, and the availability of the EcoSport in the same dealer should only make that job harder.
