Ford, just like everyone these days, is a global company. Parts come from all over the world and the products are sold in multiple markets. Am I thrilled about a China Focus? No, but I would rather drive an imported Focus from China than a SUV made in the US. The average consumer, actually closer to 99% of the consumers will never know the Focus was imported from China and most won't care. The EcoSport is from India and the original Transit was imported from Turkey. Nobody cares.
A quick history lesson, Ford has been in Europe since the early 1900's. It mostly operated separately from the US version. During WWII, bombers made by Ford at Willow Run were bombing Ford factories in Germany and France that were making equipment for the Nazi's. To protect Ford on both sides of the pond, there could be no communication or involvement between them during the war. After the war, the companies went back to making products for their markets. The legendary GT40 was built by Ford of Europe and didn't become competitive until Shelby, Moody, and the "whiz kids" figured out the engine and aerodynamics. Ford of Europe collaborated with DeTomaso with the Pantera that was sold in the US by Lincoln. The Fiesta may have been the first attempt to bring a product from Europe to the US in the late 1970's. The next world car was the Escort and was very similar between the markets for the first few years. The European model became a monster and the US one became something barely suitable for a rental car. Ford shared cars under the Merkur name in the 1980's with limited success. Ford tried the world car again in 1995 with the Contour and Mondeo. It was too small of a sedan for the US market and died. Sad since it was probably the best sedan that wasn't German. Horribly complex and expensive to repair, but a winner in terms of a proper driver's sedan. Next up with the Focus in 2000 and Cougar. Ford once again turned the US Focus into a rental car and the European version became a hot hatch. Under Mulally, Ford once again tried to combine products under the "One Ford" program. The US got the Transit, C-Max, Fiesta, Escape, and Focus. The Mondeo and Fusion were eventually merged as well. Europe got the Mustang, Edge, and shared the Escape/Kuga, Focus, Fiesta, Mondeo/Fusion, and probably some other stuff. Over the course of all of this, Ford has had JV's and owned all sorts of car companies. Jaguar, Land Rover, Aston Martin, Mazda, Volvo, Daewoo (nobody remembers that the Korean's built the Aspire and I think the Festiva), and countless other companies around the world. This created a vast manufacturing and supply network that can supply both regional and global markets. Ford's standardized assembly line and quality systems mean a car built in China should have the same quality as one built in Mexico, Germany, or the US. The processes are such that it doesn't matter who puts it together. With this being a global marketplace, a worker in China making a Ford that I buy can probably buy a Buick that somebody in the US made. Assuming of course that tariffs and other trade games aren't messing up the system that should work great for everyone. Would I buy a Chinese Focus ST? Yeah, I don't have a problem with it. I would prefer mine to be made in Mexico, but that is because all the cars I have owned in the last 18 years have all come from Mexico and have all been flawless.
