"P3 Charging Index: The best long-distance electric cars in the US"

[Tooney]

The final ranking of the P3 Charging Index US
It leaves the Lucid Air as the vehicle best suited to long-range journeys with a CI of 1.04 across all categories. Its average charging power of 147 kW was outweighed by its low consumption, resulting in 208 recharged miles after 20 minutes. The premium sedan is, therefore, the second-ever vehicle to reach a CI higher than 1; previously, the title was held by the Kia EV 6 in July 2022, a time when the Lucid EV would not compete in Europe.

As for the Kia EV6 in the US ranking, it still comes in third overall with a CI of 0.96, corresponding to 191 miles recharged after 20 minutes. It also sets the Kia right behind the Tesla Model S Plaid with a CI of 0.97. The Kia benefits from its high charging power above 200 kW until 52% SoC, whereas the Tesla Model S Plaid charges below 200 kW already at 38% SoC.

The Porsche Taycan, with its impressive charging powers but higher consumption, ranges in fourth place with a CI of 0.77 (based on 153 recharged miles in 20 minutes) – but only in the luxury car ranking.

Note: The P3 group report used US EPA amounts for EV consumption. For Porsche Taycan it used 41 kwh per 100 miles, or about 2.4 miles per kwh. If real-world Taycan consumption is less than EPA amount, "recharged range" after 20 minutes of charging would be more than 153 miles.

It's good to see EV charging speed and consumption considered, instead of only comparing the ranges of EVs, but the authors of this report only actually measured charging times. They used EPA data for consumption.

Edit: In a Taycan charging test done by Moloughney, the Taycan achieved a range of 200 miles after only 14 minutes of DC charging.
