Marginally. Of course a BRZ is going to have bigger more powerful brakes than the Prius, and the wider tires also may have better grip on dry pavement.Whatever the conditions of those tests are, enerfy saver tyres are the worst in wet stopping, barring some extreme budgets occasionally.
Narrow non-energy saving tyres would stop that prius sooner.
For further discussion, here are the pilot super sport tires I have on my 135i.
So the narrow Michelin energy saver tires on a Prius stop better in the wet than the PSS on a BMW as well.
