If you're wondering why Ford is revealing the Fiesta outside of the US, it's because the Fiesta is a global car that sells far more units worldwide than it does back home. The current Fiesta was introduced to Americans when gas was expensive and many shoppers were looking to downsize. Sales have slowed greatly in response to the drop in fuel prices.
The new Fiesta shouldn't change too much in size, as any increase would have it start to step on the toes of Ford's Focus in the class above. Based on spy photos, the styling seems to be more evolution than revolution, with smoother lines and an updated take on the current Ford look. It's less busy and sportier than the current model, but still distinctly Ford. It's unknown whether an ST will be revealed next week, but spy photos (which you can see above) have shown what we believe to be the hot hatch's replacement. It's more likely that any performance variants will be shown at a later date.
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.
