The 6.0-litre alloy bent-eight delivers 260kW of peak power at 5600rpm and 510Nm of peak torque at 4400rpm across all V8 variants in the Australian-made Holden range (some are exported as Chevrolet, Daewoo or Buick models) and is the most powerful standard engine ever offered by Holden.
Torque delivery is said to be significantly increased at lower revs offering improved acceleration, low speed engine response and improved ease of towing than the previous 5.7-litre engine.
All new variants meet Australia’s strict new ADR79/01 emission regulations – equivalent to the EU’s Euro 3 – which came into effect on 1 January.
The L76 engine is manufactured in Mexico and will also be installed in 2007 model year sports utility vehicles for the US market.
Australian production of the MY06 Holdens starts in February at the Elizabeth, South Australia facility following A$35 million of upgrade works during the Christmas and New Year break.
More than A$400 million has been spent on these manufacturing operations in the past three years.
