Cadillac LYRIQ trim comparison
2026 Cadillac LYRIQ Premium Sport vs Signature Luxury
The LYRIQ Premium Sport starts at $63,700 while the Signature Luxury is $67,800. That $4,100 gap buys 1 meaningful difference.
$4,100 more is ~$72/month. The question is whether the added equipment will matter to you every week.
The extra $4,100 does not buy a measurable hardware change in our data. Treat the Signature Luxury as an appearance or packaging decision, not a core-trim upgrade.
The cleanest way to feel this upgrade is through the payment: about $72/month more over 60 months, or roughly $4,320 extra all-in once interest is included.
Lock one trim, change the other side, and move through exact pair pages without resetting back to the full lineup every time.
