Opel Vectra C fuel consumption - real world test

Testing the optimal fuel consumption with the facelift petrol Opel Vectra C 1.8i

Average fuel consumption on the board computer of Vectra C

Opel Vectra C is a car that is still on service, more than 15 years after it was first released. We've already tested different versions of the last generation Vectra C and almost all of them proved to be quite economical in terms of fuel consumption.

The Test 
Lat week we tested petrol 1.8i Vectra hatchback in normal weather conditions and in extra-urban traffic we managed to achieve results of under 7 liters per 100 km. This is actually quite an achievement for mid-sized vehicle with 140 hp under the hood. Yes, you have to be quite gentle with the throttle but on a longer journey it will really pay out as you might save quite a lot. 

Of course the 1.9 CDTI engine runs on even less fuel but that is expected due to the diesel's better efficiency.

The very same Opel Vectra C 1.8i achieved 7.5-7.8 liters per 100 km in mixed cycle. Urban goes as much as 12.0-12.5 liters, which is a satisfactory result but far from perfect.

Test Conclusion 
In this test we proved that petrol vehicles without LPG systems can be also economical. You just need to be gentle on the gas pedal and avoid driving aggressively.
