Testing the optimal fuel consumption with the facelift petrol Opel Vectra C 1.8i
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.
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.
"Diesel engines have some good characteristics but I believe they will become obsolete in the next 10-15 years due to environmental reasons. Hopefully hybrids and hydrogen vehicles will get more advanced and will reach wider range of consumers." Fuel consumption under 7 liters per 100 km with 2008 Opel Vectra C – achieved
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.
