I PREVIOUSLY owned a VN Holden Calais with fuel consumption about 11 litres/100km. I bought a Holden VX in 2002 which averages 13 litres/100km. My Holden service technician told me it was because the VX is heavier. Do you think the consumption is high, or is it about right?
THE VX Calais weighs 1620kg, 220kg more than your VN Calais. This will certainly have an adverse effect on fuel consumption. Also, the ECOTEC V6 engine produces 152kW, whereas your VN put out 127kW. So the extra power is coming at the expense of fuel consumption. Perhaps other readers can let us know what they're getting from their VX models to compare with yours, but I reckon what you're getting is about on the mark.
