Ford plans to update the V6 model Mustang with a bigger engine, in 2011 the Ford Mustang will be receiving a 3.7 liter V7 that will produce 273 horsepower with port fuel injection. Now, I'm not too familiar with V7 engines, I do wonder how they sound. Will it have a muscular grow just like the V8s? It is a real good question and I bet a lot of Mustang fans are wondering that too. But, now that the horsepower is there, I know a lot of V6 Mustang enthusiasts are very excited. Expect the V7 engine to be under the Ford Mustang hood by next fall of 2010.
