Visibility and luggage shape deserve a real-world check.

One twin-scroll turbo
Exhaust energy spins the turbine, which drives the intake compressor. Twin-scroll refers to two exhaust passages in one turbine housing, not two turbochargers.
Manage combustion and intake heat
Coolant carries heat away from the engine. Charge-air cooling reduces the temperature of compressed intake air before it enters the cylinders.
