How is the climbing power of a 1.5L automatic transmission car on uphill roads?

[DeDakota]

1.5L automatic transmission cars may struggle slightly when climbing uphill. Manual transmission models or those with dual-clutch transmissions that have high transmission efficiency might perform better, but CVT or AT torque converter transmissions could face some difficulties. The 1.5L naturally aspirated engine itself provides average power, and when combined with an automatic transmission, it might struggle on uphill roads. If the car's trunk is loaded with additional luggage, the performance could be even more compromised. When driving an automatic transmission car on long uphill roads or mountain roads, it's best to switch to manual mode if the transmission has one, locking the gear in 1st or 2nd. Some automatic transmission models also have an L gear, where L stands for 'low,' specifically designed for climbing. If the transmission lacks both manual mode and an L gear, you can switch to S mode, where S stands for 'sport.' In S mode, the transmission shifts gears more slowly, and the engine's RPM increases, making the throttle more responsive. In this mode, the engine can reach the redline RPM in each gear before shifting.
