It would be unfair to give a verdict here, the build quality is not certain to a particular brand and it may vary from vehicle to vehicle. In general, all the aforementioned manufacturers offer good build quality.
No, Skoda Kushaq will be a petrol-only offering with two engine options: 1.0-litre TSI (115PS/175Nm) and 1.5-litre TSI (150PS/250Nm). The smaller engine will get the choice of 6-speed manual and automatic transmissions as seen in the Polo, while the more powerful engine will be offered with a 7-speed DSG automatic and a 6-speed MT.
In my opinion, smaller engine will competitive for sonet & venue... while powerful engine can be creta & seltos again several factors determine the success of kushq .. like boot size, leg room, mileage per litter & after sales response.. 🤞
