It is amazing how much difference an engine can make to a car. With the 2011 Mustang GT, Ford redesigned its V-8, modernizing it with an aluminum block, double overhead cams, and variable valve timing. The result is a big power gain over the previous V-8 and EPA fuel economy numbers of 17/26.
You might be able to get in the EPA range with the Mustang, if you keep the tachometer pointing around 1,500 rpm. But if you want to enjoy the exhaust note, which sounds something like a thousand wrench jockeys clearing their throats in harmony, expect around 15 mpg in real-world driving.
Ford's Sync technology adds decidedly non-retro integration with phones and MP3 players, along with offboard services such as route guidance. And you can go really high-tech with a hard-drive-based navigation unit showing traffic and gas prices, that latter an essential data point for the Mustang GT.
