The title should be updated as it is misleading in a critical way.

The word "big" suggests the size and weight of the battery is bigger, which is not the case. That would be entirely unremarkable. Their quote directly states this: "It's relatively easy to achieve more range by adding progressively more batteries, but gaining 'dumb range' that way increases weight and cost, and reduces interior space." He continued, "Lucid Air has achieved its remarkable range whilst also reducing battery size"

A better title: "Lucid Air's EV 113.0 KWh Battery Is More Powerful, Efficient, and Lighter-weight Than Tesla's"
