What search winners do that generic comparisons don’t
The top-ranking comparison pages win because they answer an explicit buying job: which one is more efficient, which one is safer, which one is larger, which one has the broader powertrain range. Pages that only dump two brochures side by side rarely hold clicks.
This comparison uses the newest verified generation of each model as the headline lens, then routes you into the exact generation sheets for the trim-level details. That is more durable than comparing incentives or dealer inventory, and more trustworthy than hiding missing data behind a made-up score.
