My 2019 SL Plus was still climbing at 101 by GPS (speedometer indicated the same) with OEM tires inflated to 44 psi. 2015 SL reached governed speed of 94 by GPS with original size tires, would go a little faster after I put 215/55 R17 tires on it. 2011 was governed to 93 on speedometer (which was fairly accurate after programming adjustment in service menu on navigation system), again with tires inflated to 44 psi cold.
