Nissan Sentra B18

2020–2026 · B18 · sedan

Eighth-generation Sentra. 2.0L PR20DE I4 (149hp / 146 lb-ft), bigger engine than the outgoing B17. Xtronic CVT only, manual transmission discontinued. Independent multi-link rear suspension (a real upgrade from the previous torsion-beam setup). FWD. Visually closer to a small Altima than the old Sentra. Significantly improved chassis dynamics for the segment, though the CVT still defines the driving feel.

Watch out: Xtronic CVT is the long-term variable. Reliability data on the B18 specifically is still developing; the chassis hardware is much better than the B17 but the powertrain story is a continuation. Otherwise no major scandals as of 2026.
