When the 2010 Mustang was unveiled at the LA Auto Show last November, a collective groan arose from the crowd when it was revealed that the 2009 engine lineup was essentially being carried over. This was particularly true for the base V6 model being propelled by the ancient 4.0-liter V6 which dates back to the 2.8-liter Capri engine of the 1970s. At the debut, Ford asked us to be patient and promised that powertrain upgrades were forthcoming.
Ever since the 3.5-liter V6 debuted in the Edge and Lincoln MKX a couple of years back, Mustang have fans have wanted to see it under the hood of their favorite pony. The problem is that engine was designed for transverse front-wheel drive applications and needed some significant reworking to go into rear-drive layouts. That work has been ongoing in order to mount the new twin-turbo EcoBoost version in the F-150 pickup next year. This work is expected to translate into a normally aspirated version of the 3.5 or 3.7-liter V6 for the ponycar about a year from now, likely for the 2011 model year.
In fact, it's now being reportedly by The Mustang News that Ford showed a 3.7-liter Mustang at an employee townhall meeting recently, although no specs were revealed. In the MKS, the 3.7 churns out 273 hp with port fuel injection. With direct injection coming to the 3.5 EcoBoost, a normally aspirated DI 3.7 can't be out of the question either, with 300+ hp to match the heavier Chevrolet Camaro. Now, about that V8...
