Easily... as in the tech is already there. 10 years ago BMW estimated a 5:15 was possible [1]. Since then we've had a decade+ of tire, aero, power-unit and transmission development, not to mention a number of 'Ring resurfacing efforts. There was no DRS or KERS back then either.

I don't think it'd cost mid 9-figures to integrate and tweak technology that is already well-understood. But then again it is [M]otorsport, where the [M] stands for Money. Red Bull could likely do it for low 8-figures with Mr. Max in the seat.
