What’s New for ’11

  • The 4.8L V-8 is now the base engine for 2500-Series passenger vans.
  • StabiliTrak stability control is standard across the board, for both passenger and cargo variants, while a locking rear differential is optional.
  • OnStar generation 9.0, which boasts improved voice recognition, is now standard on passenger vans and available on some cargo models.
  • A new 3500-Series passenger van joins the lineup, and is powered either by the standard 6.0L V-8 or the optional Duramax 6.6L V-8 Turbodiesel, both of which are mated to a 6-speed automatic transmission.
  • The DuraMax V-8 Turbodiesel receives a host of improvements for model year ’11. It is both more powerful and up to 11% more fuel efficient than the outgoing model, and NOx emissions have been reduced by up to 63% thanks to a more robust exhaust gas recirculation system. The piezo-electric common-rail fuel delivery system operates at 30,000 psi (2,000 bar) and is B20-biodiesel compatible. The engine can be cold-started in temperatures as low as -20 F (-29 C) in under three seconds without using the block heater, according to GM.
  • An optional automatic heater burns diesel fuel to heat the cabin until the engine reaches normal operating temperature. It is integrated with the chassis, self-contained and does not share coolant with the engine.
