If Toyota is preparing to give us a hot hybrid version of the Toyobaru with the assumption that it will be more fuel-efficient that way, let me reaffirm that if fuel-efficiency is a real concern and not merely a marketing operation to promote Toyota's hybrid technology which will necessarily sacrifice lightweight in order to accommodate the heavy batteries or the also heavy high energy storge capacitors then if it's all about fuel-efficieny with increased performance NOTHING could be better than a uprated version of the Subaru boxer diesel engine similarly to what Toyota have done to the Subaru boxer petrol engine in the current Toyobaru. Moreover, since both the petrol and the diesel version have the same exact bore x stroke dimensions, 86 mm x 86 mm, the number that gave the name to the Toyota GT86 and the number which corresponds to the exact diameter of the Toyobaru's tail pipes can be maintained!
Just look at the fuel consumption shown on the Toyobaru's computer after a reset when going WOT all the way through the gears to top speed in a downhill (yet a favorable condition)
