Of course, Porsches and Audis routinely beat their EPA estimates in Moloughney's 70-mph tests. However, they use the more-stringent 2-cycle EPA test instead of the more-forgiving 5-cycle test that Lucid and Tesla opt to use. Thus, Porsches and Audis start with very low EPA range estimates (just over 200 miles) that are easy to beat in highway driving. If Moloughey got 490 miles or above in the Lucid range test, it means that the Air almost doubled the Porsche highway range on a 118-kWh battery vs. the 92-kWh battery in the Porsche.
A 538-mile range from Moloughney against EPA estimates would be spectacular -- but anything in the upper 400's would be very good, indeed, especially if he did the test in his usual New Jersey venue in January.
