I've had a Dacia Bigster Journey 155 Full Hybrid for half a year. I had high expectations of this car beforehand and even those have all been exceeded. Truly a wonderful car.

Sensible and practical car. Drives okay. Low fuel consumption in summer. Good interior and cargo space. Interior feels cheap. Noisy in some situations. Sufficient ground clearance even for poor roads.

If the Bigster comes as a Hybrid 4x4 G150 automatic, it’s an interesting car. I’m currently leasing a Sandero Stepway running on LPG and will return it in November. Unfortunately that engine option isn’t offered in the Jogger, which makes the Bigster appealing to me. We’re fans of LPG — and now even with an automatic.
