Pros & cons
Pros
- Strong fuel economy for a premium-badge sedan (low-30s mpg combined).
- Standard 201-hp 2.4L i-VTEC four paired with a quick, well-sorted 8-speed dual-clutch automatic, one of the better DCTs, smooth in normal driving.
- Excellent reliability and low running costs from Honda mechanicals, RepairPal rates it near the top of the luxury-compact class.
- AcuraWatch driver-assist safety suite available, then standard from 2019.
- Affordable entry into luxury-brand ownership with strong resale value.
Cons
- Light steering and understeer-prone handling, secure but not engaging to drive.
- Interior materials and a dated dual-screen infotainment feel closer to the Civic it is based on than to true luxury rivals.
- Tight, narrow rear seat, difficult for three adults or taller passengers.
- No Apple CarPlay / Android Auto on earlier refresh cars (added for 2018).
- The 8-speed dual-clutch can feel hesitant or jerky at low speeds and in stop-and-go traffic.
