The “Bobcat” is a 5.0-liter V8 that features turbocharging and two independent fuel injection systems. The primary system utilizes traditional port injection to deliver gasoline to the cylinders, while the secondary system injects E85 directly into the combustion chambers.  E85 is an alcohol fuel mixture that typically contains a mixture of up to 85% denatured fuel ethanol and gasoline or other hydrocarbon (HC) by volume. On an undenatured basis, the ethanol component ranges from 70% to 83%. There are questions about the use of biofuels like E85, ostensibly to reduce carbon emissions, when they may have a large carbon footprint according to one study.

Now that Ford has officially revealed the new 5.0-liter V8 for the 2011 Mustang GT, (more…)
