With the Suzuki Across we are seeing 36/37 mpg in charge mode, on a run with a completely deleted battery we are averaging around the 55 mpg mark. Why such a big difference between the Hyundai and Toyota hybrid systems ?
The simple answer – Toyota have mastered hybrid powertrains and are leaders in the technology.
Even if we all had exactly the same car, mpg would still vastly differ, as we all drive different roads at different speeds, accelerate out of junctions differently and of course use regen differently. If we all drove the same route, at the same ambient temperature, same traffic conditions and same speeds, we would get a better idea.
The downfall with the Tucson, is the lack of an independant charge mode button, along with the lack of user defined control of functions. I.E The driver should be able to define when in HEV mode (Hybrid), whether the battery should charge to 100% or use the remaining battery % and keep it within that % + or – 10%, regardless of satnav use, acc or road driven. As it stands, the Tucson is too eager, to want to charge out of EV.
