To be honest, not the nicest car to look at. I would say it is the ugliest of the 3. But they will make up for it with the glorious 3.7L V8 sound.
Oh, and power wise: the car makes a combined 1000hp. 520hp for the V8, 420 from the electrical system. Although we probably will never see the full 1000hp in action because of the fuel limit.
It seems as if Toyota also has done enough testing to be up to pace from the beginning, as they report to have driven 18000km with the new LMP1. Not bad considering that Porsche is developing since 2012.
If it only would look like the early TSO30...
