How much weight o r load does adding accessories and people affect performance and durability of Kia Stonic’s drivetrain?

In Pakistan, cars often carry heavy loads—many passengers, AC running, luggage on roof racks, etc. How does the Kia Stonic perform under such loads? Do owners notice degradation in fuel economy, engine strain, transmission stress, o r increased wear if the car is carrying near its maximum capacity? Are there any reports of mechanical issues arising specifically because of overloading o r regular loading beyond what is comfortable?

According to the specs, the Stonic has a kerb weight of about 1,185 kg.

Given that, when you add more load—extra passengers, luggage, roof accessories, AC use etc.—the vehicle will naturally suffer somewhat in acceleration, fuel economy, and climbing/hilly performance. Owner feedback suggests that with full loads and on inclines, the Stonic engine feels more sluggish, especially at low RPMs. The need to either down‑shift o r push the engine harder is noticed.

Durability doesn’t seem to have major complaints yet in terms of drivetrain failure due to load, but frequent heavy loading o r constant use at full capacity especially in hot climates o r with poor fuel may stress components more engine, transmission, suspension. Some owners caution that the Stonic is best treated with realistic expectations—e.g. dont expect sedan o r SUV‑level performance when heavily loaded. Also, maintaining correct tyre pressures, timely servicing, and avoiding aggressive driving seem to help mitigate strain.
