According to Ward's Auto, an experimental 6.2-liter, direct-injection V8 producing upward of 500 hp could be factored into the next Chevrolet Camaro equation. The engine would coincide with the Gen V version of the small-block V8, based on GM's existing all-aluminum Gen IV (L92), which powers the Cadillac Escalade, GMC Yukon Denali and Hummer H2. According to Wards, the prototype powerplant resides in the engine bay of an Escalade being tested at GM's proving grounds. One GM engineer says it's developing "well north" of 450 horsepower, a 10 percent increase in low-end torque and three percent to six percent better fuel economy. That from the new injection system, which features eight high-pressure injectors that squirt fuel directly into the side of the combustion chamber at 2,250 pounds per square inch.
