A Hilux is a 2.5 D4D Diesel Engine while a Terios has a puny 1.5 Petrol engine.
The Hilux is a 4x4 truck which seats five.
The terios is a Mini Suv which seats seven.
Comfort wise the terios may be a bit better as the hilux has a leaf spring suspension at the back.
The Hilux would definitely have more torque and power than a terios.Think of seven passengers in a 1.5 liter vehicle
The terios is a full time 4 wd with a button operated central differential lock.
The Hilux is a part time 4wd without a differential lock on the Pakistan model as far as my knowledge is concerned some one please correct me on this.
Both are manual as the terios is available only as automatic in 2wd.
Basically the have totally different classes all together.
