Inifiniti, Nissan's high-end brand, is still new on our shores. You certainly don't see many of them about. Still, it seems Inifiniti produces some fairly brisk vehicles.
Inifiniti isn't the only luxury brand to make a hybrid, though. Porsche produces a hybrid version of the Panamera. Both are very quick and rather desirable, but Infiniti was keen to see which was faster.
