The Tata Sierra and the Kia Seltos are among the few midsize SUVs to offer a diverse range of engines, namely a 1.5-litre naturally aspirated petrol, a 1.5-litre direct-injection turbo-petrol and a 1.5-litre diesel. Depending on the engine chosen, both offer a variety of gearbox options, including manual, CVT, DCT, iMT and torque-converter automatic. In this article, we compare the ARAI mileage figures of both across all their respective powertrain options to find out which offers higher claimed efficiency numbers.
Tata Sierra vs Kia Seltos: Claimed mileage comparison
The Sierra is more efficient across all engines except for the turbo-petrol
The Sierras’s claimed mileage figures for the naturally aspirated petrol engine are higher than those for the Seltos. It is ahead of the Seltos by 0.9kpl in manual guise, while its DCT variant is 0.4kpl more efficient than the Seltos petrol-CVT. This is because the Sierra’s naturally aspirated engine operates on the Atkinson cycle that prioritises efficiency.
It’s the same case with diesel engines, where the Seltos’s figures fall short of the Sierra’s by 1.86kpl and 1.42kpl for the manual and automatic gearboxes, respectively. But when it comes to turbo-petrol automatics, the Seltos’s turbo-DCT has a 2.2kpl higher claimed mileage than the Sierra’s turbo-petrol with a 6-speed automatic. The Seltos also offers an iMT gearbox with its turbo-petrol engine, with a mileage of 15.6kpl.
