Amidst the "19 new engines" announcement from General Motors Thursday was a brand-new engine of particular significance for the power-hungry (and aren't we all?): a 3.6 liter all-aluminum V6 with direct injection and variable valve timing. The new V6 is promised for the 2008 model year, with a launch vehicle "to be announced."

Destined to be GM's highest specific output non-turbo engine, the new V6 sounds like a natural for the V6 versions of the new Camaro. The new engine promises a 15 percent boost in horsepower over GM's current V6 powerplants, accompanied by an 8 percent increase in torque. Lower emissions and better fuel economy accompany the power boost.

Features of the high-tech V6 include:
  • Aluminum engine block and cylinder heads
  • Dual overhead cams with four valves per cylinder and silent chain primary drive
  • High-pressure, engine-driven fuel pump
  • Advanced multi-outlet fuel injectors developed to withstand high pressure and heat
  • Stainless steel, variable pressure fuel rail
  • Four-cam phasing (VVT – see description below)
  • 11.3:1 compression ratio
  • Aluminum pistons with floating wrist pins and oil squirters
  • Polymer coated piston skirts
  • Forged steel crankshaft
  • Sinter-forged connecting rods
  • Structural cast-aluminum oil pan with steel baffles
  • Electronic throttle control with integrated cruise control
  • Coil-on-plug ignition
  • Advanced direct injection capable engine control module (ECM)
