Ford C-Max

The Ford C-Max is having a rough time. Sales for the five-door hybrid hatchback were down 39.1 percent in March to 2,295 cars, and sales from January through March were down 42.5 percent to 5,566 units. In an interview with The Detroit News, Ford Americas boss Joe Hinrichs places the blame on lowering the model's fuel economy rating.

"We're definitely seeing consideration on C-Max decline over time. We need to reinvest in the product because it's a great car," said Hinrichs to The Detroit News.

The company was hit with bad publicity over the C-Max when owners in multiple states filed class action lawsuits that alleged the cars weren't able to meet the stated fuel economy. Ford eventually re-rated the model from 47 miles per gallon city, highway and combined to 40 mpg city, 45 mpg highway and 43 mpg combined. To soften the blow of the change, the automaker sent checks to the owners to make up some of the difference. Initially, Ford claimed that demand remained strong for the hybrid. However, the latest sales figures and Hinrichs' statement seem to show the opposite.

Hinrichs also says a replacement for the company's MyFord Touch infotainment system is in the works. He claims that the current system is being held back by software limitations. However, a replacement is at least year away. Ford is rumored to be considering switching from Microsoft to a Blackberry QNX-based infotainment system.
