I don't think there is much risk in the industry. Sales of full-size SUVs of yore (the gas guzzling V8s based on full-size trucks) are down, people want the newer, smaller, lighter 4-cylinder crossover and it will end the sedan era. Ford isn't alone here either -- every manufacturer is pumping out models of crossovers based on sedans. Sedans are either pivoting into territory that sportier cars used to occupy (Toyota Camry) or morphing into entry luxury vehicles (Honda Accord). Even with this pivoting, year-over-year sales of cars like the Nissan Altima and Honda Accord are significantly down.
Real example: Mazda 3 sedan vs Mazda CX-5 crossover SUV. They use the exact same 4 cylinder engine pushing 155 horses. The sedan gets 30/41 mpg and the crossover 26/35. People aren't going to give up their higher ride height and comfy seats for 5 mpg. Another example to consider is that sales of crossovers are way up in europe, despite having gas that costs nearly double that of the United States.
Ford is making a logical move. Their 4 cylinder ecoboost engines are efficient and they want to introduce hybrid drivetrains, even on their muscle car.
