Lamborghini Revuelto has 9,500 RPM. They have said Lamborghini Temerario can reach maximum revolutions of 10,000 rpm. This is one of the highest among the avaailable cars
The Temerario revs to over 10k RPM, and from the videos I have seen does not sound or feel like it is straining. Some cars rev to 8500, and you can literally feel like they are falling apart through the screen. Big up to the engineers on this one.
