The Skoda Kushaq is a good choice for your requirements. The 115hp, 1.0-litre TSI engine is peppy, the cabin is comfortable, and the build quality is good too. Coming from your Ford Figo, you will also enjoy the driving experience. As for fuel efficiency, yes, the turbo-petrol engine will be less efficient than your current diesel. In our efficiency tests, the Kushaq 1.0 TSI with the 6-speed AT delivered just 8.5kpl in the city and 12.4kpl out on the highway. However, the updated Kushaq comes with an 8-speed gearbox, so expect slightly better efficiency.
As for the Volkswagen Taigun facelift, it will essentially be the same car as the Kushaq. So there won’t be much difference in terms of performance, efficiency or comfort. The notable differences will be in the exterior styling and certain features.
So it only makes sense to wait for the facelift if you really like the look of the Taigun better than the Kushaq.
