Chevy Impala E85 FFV
E85 Flex Fuel Chevrolet Impala
An all-new 3.6L V-6 DOHC direct injection engine with variable valve timing and E85
FlexFuel capability is standard on all Impala models. It is the same engine that powers the 2012 Camaro 2LS model. Although it provides 300 horsepower (224 kW) in the Impala, it delivers an EPA-estimated 30 mpg highway. A six-speed automatic transmission replaces the previous model year’s four-speed gearbox for even more efficiency. Key engine features include:
Engineers removed nearly 20 pounds from the engine while retaining strength and durability, for improved efficiency and driving dynamics.
New cylinder heads bring a revised intake port design that enhances airflow to the combustion chambers for greater efficiency.
The 3.6L V-6 uses a new fuel pump for the direct injection system, along with a new, isolated fuel rail. The new fuel pump is quieter, while the isolated fuel rail further reduces fuel system noise.
The engine was redesigned with additional support ribs on the backside and an additional fastener to lessen noise and vibration. Inside the engine, the powdered metal connecting rods use a higher ratio of copper, which makes them stronger and lighter. Also, the camshafts feature new saddle-type caps for improved durability.
