I can't find any reference that says the model y ever had over 400 miles of range. The website even claims it maxed out at 337 miles, not 427. Could the writers offer their source for this?
Yes, but the problem is that all Chinese competitors at that price point have 800V-900V powertrains that offer 10-15 minute charging times, and some even offer drive-by-wire and rear wheel steering, not to mention the other extras and interior appointments. The Juniper will only fly in the US and Europe with those aging specs.
Tesla announced the Model Y Juniper refresh with two light bars, a quieter ride and vented seats, but with a price higher than the facelift's predecessor, and middling specs.
