The idea of an EcoBoost V6 powering the next-generation Mustang has been kicked around the Autoblog offices ever since Ford announced the new twin-turbocharged, direct-inject V6 earlier this year. According to MotorTrend, FoMoCo is now seriously considering offering the new mill along with its standard 4.0-liter V6 and a set of new V8s. The Blue Oval is contemplating equipping the new 'Stang with an all new 5.0-liter V8 that would find its way under the hood of a limited edition Boss 302 or the 315-hp, 4.6-liter V8 found in the Bullitt. Either way, buyers can keep things traditional or go for the turbo V6 while still retaining the output characteristics of a big V8. The move comes as new CAFE regs are beginning to be taken seriously by all automakers, including GM, which recently canceled its DOHC V8 engine program.

Shelby versions of the Mustang will likely continue through the end of the year and maybe beyond, with a GT500 version being available soon after the redesign goes on sale late in 2009. It's still rumored that the new sheet metal adorning the 2010 Mustang will take some cues from the Giugiaro concept, including a set of wider haunches that are more reminiscent of the fastback's shoulders, along with a new rear bumper design, new front fascia and plenty of wheel and color choices. Inside, the instrument panel will get a facelift to allow more room for navigation and audio controls, while improvements will be made to create a more "driver-centric" environment.

Despite all the talk about a more fuel-efficient V6, Ford is reportedly also developing a supercharged version of its 5.0-liter V8 to be stuffed into a new flagship model that would compete with the Chevy Corvette ZR1 and Dodge Viper SRT10.
