Is the Alcazar's 1.5L turbo petrol engine underpowered for a 7 seater?

Hyundai Alcazar comes with a 1.5 liter turbo petrol engine, which is smaller in displacement than some of its rivals in the 7 seater SUV segment. This has sparked conversation on whether or not this engine produces enough power and torque for a vehicle with a size like this (especially on a loaded vehicle with passengers and luggage). The turbocharging, they say, makes up for the smaller displacement, but the engine is still adequate, while others think a bigger naturally aspirated engine would be a better fit for this type of vehicle. It also delves into the performance, fuel efficiency and emissions tradeoffs in today's SUVs and whether downsized turbocharged engines are the way to go in large vehicles.
