Both use the same 1.2-litre Kappa petrol engine, but the Grand i10 Nios is the smaller, more affordable car, while the i20 is a larger premium hatchback. The Nios also offers a factory-fitted CNG option and an AMT, while the i20 offers a smoother IVT automatic.<\/p>\n\n\n\n<p>So, Grand i10 Nios or i20, which is better for mileage? In this Hyundai Grand i10 Nios vs Hyundai i20 comparison, we look at ARAI-claimed and real-world mileage for each powertrain, along with specs, fuel costs and price, to help you decide.<\/p>\n\n\n\n<div class=\"wp-block-rank-math-toc-block\" id=\"rank-math-toc\"><h2>Table of Contents<\/h2><nav><ul><li><a href=\"#hyundai-grand-i-10-nios-vs-hyundai-i-20-specs\">Hyundai Grand i10 Nios vs Hyundai i20 Specs<\/a><\/li><li><a href=\"#hyundai-grand-i-10-nios-vs-hyundai-i-20-arai-claimed-mileage\">Hyundai Grand i10 Nios vs Hyundai i20: ARAI Claimed Mileage<\/a><\/li><li><a href=\"#hyundai-grand-i-10-nios-vs-hyundai-i-20-real-world-mileage\">Hyundai Grand i10 Nios vs Hyundai i20: Real-World Mileage<\/a><\/li><li><a href=\"#hyundai-grand-i-10-nios-vs-hyundai-i-20-fuel-cost-comparison\">Hyundai Grand i10 Nios vs Hyundai i20: Fuel-Cost Comparison<\/a><\/li><li><a href=\"#hyundai-grand-i-10-nios-vs-hyundai-i-20-price\">Hyundai Grand i10 Nios vs Hyundai i20 Price<\/a><\/li><li><a href=\"#summary\">Summary<\/a><\/li><li><a href=\"#fa-qs\">FAQs<\/a><\/li><\/ul><\/nav><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"hyundai-grand-i-10-nios-vs-hyundai-i-20-specs\">Hyundai Grand i10 Nios vs Hyundai i20 Specs<\/h2>\n\n\n\n<p>The specifications of the <a href=\"https:\/\/www.spinny.com\/cars\/hyundai\/grand-i10-nios\/?utm_source=ToyotaInnovaHycrossvsMarutiInvictoMileageComparison&amp;utm_medium=BlogLink\">Hyundai Grand i10 Nios<\/a> and the <a href=\"https:\/\/www.spinny.com\/cars\/hyundai\/i20\/?utm_source=ToyotaInnovaHycrossvsMarutiInvictoMileageComparison&amp;utm_medium=BlogLink\">Hyundai i20<\/a> help explain the difference in their mileage.

The i20 costs more but is a bigger, more premium hatchback with more space and features, and its IVT offers a smoother automatic experience. Our <a href=\"https:\/\/www.spinny.com\/blog\/hyundai-i20-alternatives-competitors-of-hyundai-i20\/\">i20 alternatives guide<\/a> shows how it compares with other premium hatchbacks.<\/p>\n\n\n\n<p><strong>Also Read: <\/strong><a href=\"https:\/\/www.spinny.com\/blog\/comparison-hyundai-exter-vs-hyundai-grand-i10-nios\/\">Comparison: Hyundai Exter vs Hyundai Grand i10 Nios<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"summary\">Summary<\/h2>\n\n\n\n<p>When we compare the Grand i10 Nios and the i20, their shared 1.2-litre petrol engine delivers similar real-world mileage with manual gearboxes, with the i20 slightly ahead on the highway. With automatics, the Nios AMT returns better real-world mileage than the i20 IVT, especially in city traffic.<\/p>\n\n\n\n<p>The Nios CNG is the clear running-cost winner, averaging 22-25 km\/kg and costing around half as much to fuel as the petrol models. The i20 does not offer a CNG option.<\/p>\n\n\n\n<p>Therefore, if you want the lowest purchase price and running costs, or a factory-fitted CNG option, the Grand i10 Nios is a great choice. If you want a bigger, more premium hatchback with a smooth IVT automatic, the i20 justifies its higher price.<\/p>\n\n\n\n<p><strong>Related Blogs:<\/strong><br><a href=\"https:\/\/www.spinny.com\/blog\/hyundai-i20-vs-tata-altroz-real-world-mileage-comparison\/\">Hyundai i20 vs Tata Altroz: Real World Mileage Comparison<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"fa-qs\">FAQs<\/h2>\n\n\n<div class=\"saswp-faq-block-section\"><ol style=\"list-style-type:none\"><li style=\"list-style-type: none\"><h3 class=\"\"><strong>Q.
