The Maruti Swift comes with a 1.2-litre petrol engine, which can be availed with manual and AMT gearbox options in addition to a factory-fitted CNG variant, whereasthe&nbsp; Tata Altroz has petrol, diesel and CNG powering options along with various gearbox options such as manual, AMT, and DCT. Maruti Swift boasts of claiming mileage of up to 25.75 km\/l for petrol variants and 32.85 km\/kg in CNG variants, while the Tata Altroz is claimed to have mileage of 23.64 km\/l for its diesel version and 27.8 km\/kg in CNG.<\/p>\n\n\n\n<p>The fourth-generation Swift launched in India in 2024 with Maruti\u2019s lighter and more efficiency-focused three-cylinder Z-Series engine. The current Altroz is the facelifted model introduced in 2025 and takes a different approach by offering more powertrain variety, a larger cabin and the option of diesel. So, while the Swift starts with a clear efficiency advantage on paper, the real-world comparison becomes more interesting once petrol automatics, CNG versions and the Altroz diesel are considered.<\/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=\"#maruti-swift-vs-tata-altroz-specs\">Maruti Swift vs Tata Altroz Specs<\/a><\/li><li><a href=\"#maruti-swift-vs-tata-altroz-arai-mileage-figures\">Maruti Swift vs Tata Altroz ARAI Mileage Figures<\/a><\/li><li><a href=\"#maruti-swift-vs-tata-altroz-real-world-fuel-efficiency\">Maruti Swift vs Tata Altroz Real-World Fuel Efficiency<\/a><\/li><li><a href=\"#maruti-swift-vs-tata-altroz-fuel-cost-comparison\">Maruti Swift vs Tata Altroz Fuel Cost Comparison<\/a><\/li><li><a href=\"#maruti-swift-vs-tata-altroz-price\">Maruti Swift vs Tata Altroz 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=\"maruti-swift-vs-tata-altroz-specs\">Maruti Swift vs Tata Altroz Specs<\/h2>\n\n\n\n<p>The Swift comes with a 1.2-litre three-cylinder petrol engine generating around 81.6 hp and 111.7 Nm of torque. Customers have the opportunity to select either the 5-speed manual or AMT to enjoy the ride.&nbsp; In the case of its CNG model, the engine has lower outputs, making it around 70hp and 101.8 Nm, and it can be offered in manual versions only. One of the major benefits of the Swift is its light weight, as even the petrol versions weigh only about 920925 kg,g making the engine consume less fuel while accelerating and starting and stopping.<\/p>\n\n\n\n<p>The Altroz is larger and heavier but offers considerably more choice. Its 1.2-litre naturally aspirated petrol makes 88hp and 115Nm, while the 1.5-litre diesel produces 90hp and a much stronger 200Nm. The CNG version makes around 74hp and 103Nm. Petrol buyers can choose manual, AMT or 6-speed DCT, while the diesel remains manual-only. Tata also offers a CNG AMT, giving the Altroz an automatic CNG option that the Swift does not have.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Specification<\/strong><\/td><td><strong>Maruti Swift<\/strong><\/td><td><strong>Tata Altroz<\/strong><\/td><\/tr><tr><td>Engine<\/td><td>1.2L petrol \/ CNG<\/td><td>1.2L petrol \/ 1.5L diesel \/ 1.2L CNG<\/td><\/tr><tr><td>Displacement<\/td><td>1,197cc<\/td><td>1,199cc petrol\/CNG \/ 1,497cc diesel<\/td><\/tr><tr><td>Power<\/td><td>81.6hp petrol \/ ~70hp CNG<\/td><td>88hp petrol \/ 90hp diesel \/ ~74hp CNG<\/td><\/tr><tr><td>Torque<\/td><td>111.7Nm petrol \/ 101.8Nm CNG<\/td><td>115Nm petrol \/ 200Nm diesel \/ 103Nm CNG<\/td><\/tr><tr><td>Transmission<\/td><td>5MT \/ 5AMT<\/td><td>5MT \/ 5AMT \/ 6DCT<\/td><\/tr><tr><td>Drive layout<\/td><td>FWD<\/td><td>FWD<\/td><\/tr><tr><td>Kerb weight<\/td><td>Around 920\u2013990kg<\/td><td>Heavier than Swift, variant dependent<\/td><\/tr><tr><td>Petrol tank<\/td><td>37 litres<\/td><td>37 litres<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>The Altroz has various advantages over its much heavier competitor, but its weight is not an advantage when it comes to fuel efficiency. Swift might be heavier than Altroz, but because of its lighter construction and less sophisticated drivetrain, it is winning the competition with regard to CNG and petrol mileage tests.<\/p>\n\n\n\r\n    <style>\r\n        .sp-card-wrapper { \r\n            margin: 40px auto; \r\n            border-radius: 20px; \r\n            overflow: hidden; \r\n            font-family: sans-serif; \r\n            background: #fff; \r\n            box-shadow: 0 15px 40px rgba(0,0,0,0.18); \r\n            max-width: 700px; \/* Narrower width makes the stack feel tighter *\/\r\n            text-decoration: none;\r\n            display: block;\r\n            width: 100%;\r\n        }\r\n        .sp-img-container { \r\n            width: 100%; \r\n            position: relative;\r\n            padding-top: 56.25%; \/* Fixed 16:9 ratio for a cinematic feel *\/\r\n            background: #f4f4f4;\r\n        }\r\n        .sp-img-container img {\r\n            position: absolute; top: 0; left: 0; width: 100%; height: 100%; object-fit: cover;\r\n        }\r\n        .sp-footer { \r\n            padding: 30px; \r\n            background: #2e054e; \r\n            color: #fff !important; \r\n            text-align: center; \/* Centered layout for the stack *\/\r\n            display: flex;\r\n            flex-direction: column;\r\n            align-items: center;\r\n            gap: 15px;\r\n        }\r\n        .sp-card-title { \r\n            font-size: clamp(28px, 5vw, 42px); \/* Much larger, prominent name *\/\r\n            margin: 0; \r\n            font-weight: 800; \r\n            color: #fff !important; \r\n            line-height: 1.1;\r\n            letter-spacing: -1px;\r\n        }\r\n        .sp-btn { \r\n            background: #ed264f; \r\n            padding: 18px 40px; \r\n            border-radius: 10px; \r\n            font-weight: 900; \r\n            color: #fff !important; \r\n            font-size: 16px; \r\n            text-transform: uppercase; \r\n            letter-spacing: 1px; \r\n            width: 100%;\r\n            max-width: 300px; \/* Prevents button from being too wide on desktop *\/\r\n            box-sizing: border-box;\r\n            box-shadow: 0 4px 15px rgba(237, 38, 79, 0.3);\r\n        }\r\n    <\/style>\r\n\r\n    <a href='https:\/\/www.spinny.com\/used-swift-cars\/s\/?utm_source=SwiftVsAltrozMileage&utm_medium=BlogCard' target='_blank' class='sp-card-wrapper'>\r\n        <div class='sp-img-container'>\r\n            <img src='https:\/\/assets.spinny.com\/sp-file-system\/public\/2026-06-27\/7584d9ac0dc341bd8d20bfa4e3085c60\/raw\/file.JPG?q=85' alt='Used Maruti Suzuki Swift Cars'>\r\n        <\/div>\r\n        \r\n        <div class='sp-footer'>\r\n            <h3 class='sp-card-title'>Used Maruti Suzuki Swift Cars<\/h3>\r\n            <div style='margin-bottom: 5px;'>\r\n                        <div style='font-size: 12px; opacity: 0.8; text-transform: uppercase; letter-spacing: 0.5px;'>Starting From<\/div>\r\n                        <div style='font-size: clamp(24px, 4vw, 32px); font-weight: 800;'>\u20b9 2 Lakh<\/div>\r\n                      <\/div>\r\n            <div class='sp-btn'>Explore Pre-Owned Cars<\/div>\r\n        <\/div>\r\n    <\/a>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"maruti-swift-vs-tata-altroz-arai-mileage-figures\">Maruti Swift vs Tata Altroz ARAI Mileage Figures<\/h2>\n\n\n\n<p>The Swift is among the most fuel-efficient petrol hatchbacks currently on sale. Its petrol manual claims 24.8 km\/l, while the AMT improves that to 25.75 km\/l. The factory CNG version is rated at 32.85 km\/kg, making it the strongest official mileage figure in this comparison.<\/p>\n\n\n\n<p>The Altroz petrol offers around 19.33 km\/l irrespective of whether one goes for a manual variant or an automatic one. The diesel version shows an improvement at 23.64 km\/l, whereas the CNG variant has a mileage of 27.8 km\/kg. Hence, on paper, the Altroz diesel seems to be close to the Swift petrol, but for both petrol and CNG variants, the Swift is ahead.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Car<\/strong><\/td><td><strong>Engine &amp; Transmission<\/strong><\/td><td><strong>Fuel Type<\/strong><\/td><td><strong>ARAI Mileage<\/strong><\/td><\/tr><tr><td>Maruti Swift<\/td><td>1.2L, 5MT<\/td><td>Petrol<\/td><td>24.8 km\/l<\/td><\/tr><tr><td>Maruti Swift<\/td><td>1.2L, 5AMT<\/td><td>Petrol<\/td><td>25.75 km\/l<\/td><\/tr><tr><td>Maruti Swift<\/td><td>1.2L, 5MT<\/td><td>CNG<\/td><td>32.85 km\/kg<\/td><\/tr><tr><td>Tata Altroz<\/td><td>1.2L, MT<\/td><td>Petrol<\/td><td>19.33 km\/l<\/td><\/tr><tr><td>Tata Altroz<\/td><td>1.2L, automatic<\/td><td>Petrol<\/td><td>19.33 km\/l<\/td><\/tr><tr><td>Tata Altroz<\/td><td>1.5L, 5MT<\/td><td>Diesel<\/td><td>23.64 km\/l<\/td><\/tr><tr><td>Tata Altroz<\/td><td>1.2L, 5MT<\/td><td>CNG<\/td><td>27.8 km\/kg<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>These numbers show how just looking at the official mileage figures can lead to misleading comparisons. Driving conditions, along with factors like the nature of the traffic, transmission functioning, weight of the vehicle, and the style of driving, can create bigger differences across these cars than what is indicated by ARAI numbers.<\/p>\n\n\n\n<p>Also Read: <a href=\"https:\/\/www.spinny.com\/blog\/buying-guide-tata-altroz\/\">Complete Guide to Buying a Tata Altroz<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"maruti-swift-vs-tata-altroz-real-world-fuel-efficiency\">Maruti Swift vs Tata Altroz Real-World Fuel Efficiency<\/h2>\n\n\n\n<p>The Swift petrol manual has returned approximately <strong>14 km\/l in city driving and 19 km\/l on highways<\/strong>, giving a simple combined average of around <strong>16.5 km\/l<\/strong>. The AMT returned roughly <strong>12.7 km\/l in the city and 19.1 km\/l on highways<\/strong>, averaging about <strong>15.9 km\/l<\/strong>. The manual therefore performs better in urban conditions, while both are very similar once speeds stabilise on the highway.<\/p>\n\n\n\n<p>For the <a href=\"https:\/\/www.spinny.com\/cars\/tata\/altroz\/?utm_source=SwiftVsAltrozMileage&amp;utm_medium=BlogLink\">Tata Altroz<\/a> petrol, there is no instrumented test that can be used for direct comparison, and hence it would not be prudent to give any hypothetical figures for city and highway usage. The Altroz DCT has been tested for 10.45 km\/l in the city and 18.36 km\/l on highways, meaning an average of about 14.4 km\/l. Swift AMT therefore outperform in terms of automatic testing, but the DCT technology in Altroz aids in better mileage.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><\/td><td><strong>Swift Petrol MT<\/strong><\/td><td><strong>Swift Petrol AMT<\/strong><\/td><td><strong>Altroz Petrol DCT<\/strong><\/td><\/tr><tr><td>City<\/td><td>14 km\/l<\/td><td>12.7 km\/l<\/td><td>10.45 km\/l<\/td><\/tr><tr><td>Highway<\/td><td>19 km\/l<\/td><td>19.1 km\/l<\/td><td>18.36 km\/l<\/td><\/tr><tr><td>Average<\/td><td>~16.5 km\/l<\/td><td>~15.9 km\/l<\/td><td>~14.4 km\/l<\/td><\/tr><tr><td>Approx. 37L range<\/td><td>~611 km<\/td><td>~588 km<\/td><td>~533 km<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>The CNG performance is more straightforward. Swift CNG managed to achieve 24.35 km\/kg in urban driving and 31.38 km\/kg on highways, contributing to an average of about 27.87 km\/kg. The Altroz CNG achieves 20.56 km\/kg in the city and 29.65 km\/kg on highways, giving an average of about 25.10 km\/kg. Thus, in both usage situations, the Swift wins, but the maximum advantage appears in traffic conditions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"maruti-swift-vs-tata-altroz-fuel-cost-comparison\">Maruti Swift vs Tata Altroz Fuel Cost Comparison<\/h2>\n\n\n\n<p>For this comparison, we have assumed 1,500 km of driving every month, equal to 18,000 km annually. Fuel prices are based on New Delhi rates in September 2026: approximately \u20b9102.12 per litre for petrol, \u20b995.20 per litre for diesel and \u20b986.98 per kg for CNG. The calculations use real-world mileage wherever reliable figures are available instead of relying on ARAI numbers.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"petrol-fuel-cost\">Petrol Fuel Cost<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><\/td><td><strong>Swift Petrol MT<\/strong><\/td><td><strong>Swift Petrol AMT<\/strong><\/td><td><strong>Altroz Petrol DCT<\/strong><\/td><\/tr><tr><td>Monthly Running<\/td><td>1,500 km<\/td><td>1,500 km<\/td><td>1,500 km<\/td><\/tr><tr><td>Reference Mileage<\/td><td>16.5 km\/l<\/td><td>15.9 km\/l<\/td><td>14.4 km\/l<\/td><\/tr><tr><td>Monthly Fuel Use<\/td><td>90.9 litres<\/td><td>94.3 litres<\/td><td>104.2 litres<\/td><\/tr><tr><td>Monthly Fuel Cost<\/td><td>\u20b99,284<\/td><td>\u20b99,630<\/td><td>\u20b910,641<\/td><\/tr><tr><td>Annual Fuel Cost<\/td><td>\u20b91.11 lakh<\/td><td>\u20b91.16 lakh<\/td><td>\u20b91.28 lakh<\/td><\/tr><tr><td>5-Year Fuel Cost<\/td><td>\u20b95.57 lakh<\/td><td>\u20b95.78 lakh<\/td><td>\u20b96.38 lakh<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>When covering an average of 1,500 kilometres each month, the Swift AMT is expected to save around \u20b91350 in fuel costs compared to the Altroz DCT, which comes to approximately \u20b916,000 in one year and above \u20b980,000 over five years. The Swift AMT also has lower fuel costs by about \u20b91,000 per month as compared to the Altroz DCT.<\/p>\n\n\n\n<p>The automatic comparison is particularly relevant because the Swift\u2019s AMT is designed mainly around affordability and efficiency, while the Altroz DCT prioritises smoother shifts.

The Swift CNG saves about \u20b9520 per month compared to the Altroz CNG, translating into savings of over \u20b931,000 in the long run (5 years). The Altroz diesel is also pricier in terms of fuel costs than either of the CNG models, but it does deliver considerably more torque and is thus a better choice for buyers who spend more time on highways and do not want to rely on CNG availability.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"maruti-swift-vs-tata-altroz-price\">Maruti Swift vs Tata Altroz Price<\/h2>\n\n\n\n<p>The Swift remains the more affordable car through much of the range.

However, if you need a car with more passenger space, boot space, diesel torque, or an automatic gearbox, you may find the Altroz worth considering.<\/p>\n\n\n\r\n    <style>\r\n        .sp-card-wrapper { \r\n            margin: 40px auto; \r\n            border-radius: 20px; \r\n            overflow: hidden; \r\n            font-family: sans-serif; \r\n            background: #fff; \r\n            box-shadow: 0 15px 40px rgba(0,0,0,0.18); \r\n            max-width: 700px; \/* Narrower width makes the stack feel tighter *\/\r\n            text-decoration: none;\r\n            display: block;\r\n            width: 100%;\r\n        }\r\n        .sp-img-container { \r\n            width: 100%; \r\n            position: relative;\r\n            padding-top: 56.25%; \/* Fixed 16:9 ratio for a cinematic feel *\/\r\n            background: #f4f4f4;\r\n        }\r\n        .sp-img-container img {\r\n            position: absolute; top: 0; left: 0; width: 100%; height: 100%; object-fit: cover;\r\n        }\r\n        .sp-footer { \r\n            padding: 30px; \r\n            background: #2e054e; \r\n            color: #fff !important; \r\n            text-align: center; \/* Centered layout for the stack *\/\r\n            display: flex;\r\n            flex-direction: column;\r\n            align-items: center;\r\n            gap: 15px;\r\n        }\r\n        .sp-card-title { \r\n            font-size: clamp(28px, 5vw, 42px); \/* Much larger, prominent name *\/\r\n            margin: 0; \r\n            font-weight: 800; \r\n            color: #fff !important; \r\n            line-height: 1.1;\r\n            letter-spacing: -1px;\r\n        }\r\n        .sp-btn { \r\n            background: #ed264f; \r\n            padding: 18px 40px; \r\n            border-radius: 10px; \r\n            font-weight: 900; \r\n            color: #fff !important; \r\n            font-size: 16px; \r\n            text-transform: uppercase; \r\n            letter-spacing: 1px; \r\n            width: 100%;\r\n            max-width: 300px; \/* Prevents button from being too wide on desktop *\/\r\n            box-sizing: border-box;\r\n            box-shadow: 0 4px 15px rgba(237, 38, 79, 0.3);\r\n        }\r\n    <\/style>\r\n\r\n    <a href='https:\/\/www.spinny.com\/used-altroz-cars\/s\/?utm_source=SwiftVsAltrozMileage&utm_medium=BlogCard' target='_blank' class='sp-card-wrapper'>\r\n        <div class='sp-img-container'>\r\n            <img src='https:\/\/assets.spinny.com\/sp-file-system\/public\/2026-05-28\/c5780a632dd5401facda0180e3c20f53\/raw\/file.JPG?q=85' alt='Used Tata Altroz Cars'>\r\n        <\/div>\r\n        \r\n        <div class='sp-footer'>\r\n            <h3 class='sp-card-title'>Used Tata Altroz Cars<\/h3>\r\n            <div style='margin-bottom: 5px;'>\r\n                        <div style='font-size: 12px; opacity: 0.8; text-transform: uppercase; letter-spacing: 0.5px;'>Starting From<\/div>\r\n                        <div style='font-size: clamp(24px, 4vw, 32px); font-weight: 800;'>\u20b9 4 Lakh<\/div>\r\n                      <\/div>\r\n            <div class='sp-btn'>Explore Pre-Owned Cars<\/div>\r\n        <\/div>\r\n    <\/a>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"summary\">Summary<\/h2>\n\n\n\n<p>The <a href=\"https:\/\/www.spinny.com\/cars\/maruti-suzuki\/swift\/?utm_source=SwiftVsAltrozMileage&amp;utm_medium=BlogLink\">Maruti Swift<\/a> is the clear mileage winner in petrol and CNG form. Its petrol manual returned around 14 km\/l in the city and 19 km\/l on highways, while the AMT averages close to 15.9 km\/l across the tested conditions. The Altroz DCT is slightly thirstier at roughly 14.4 km\/l combined, although it offers the more refined automatic transmission.<\/p>\n\n\n\n<p>The comparison remains constant regarding CNG vehicles. The Swift CNG delivered mileage of about 27.87 km\/kg, against 25.10 km\/kg in the case of Altroz CNG. Thanks to its lighter weight and Z-Series engine, Swift is known for very good fuel economy for city rides.<\/p>\n\n\n\n<p>The Altroz does, however, offer something the Swift cannot: diesel. Its 1.5-litre diesel produces 200Nm and is well suited to frequent highway running. Overall, choose the Swift for maximum petrol or CNG efficiency and lower running costs, while the Altroz is better suited to buyers who want more space, greater powertrain choice, diesel torque or a more sophisticated automatic.<\/p>\n\n\n\n<p>Also Explore: <a href=\"https:\/\/www.spinny.com\/blog\/maruti-suzuki-swift-image-gallery-interior-exterior\/\">Maruti Suzuki Swift Image Gallery: Interior, Exterior<\/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\"><h5 class=\"saswp-faq-question-title \"><strong>Q. Which has better mileage, Maruti Swift or Tata Altroz?<\/strong><\/h5><p class=\"saswp-faq-answer-text\">The Maruti Swift has better mileage in comparable petrol and CNG versions. The Swift petrol claims up to 25.75 km\/l, while its CNG version claims 32.85 km\/kg. The Altroz petrol claims around 19.33 km\/l and CNG approximately 27.8 km\/kg.<\/p><li style=\"list-style-type: none\"><h5 class=\"saswp-faq-question-title \"><strong>Q. What is the real-world mileage of the Maruti Swift petrol?<\/strong><\/h5><p class=\"saswp-faq-answer-text\">The Swift petrol manual has returned around 14 km\/l in city driving and 19 km\/l on highways. The AMT returns approximately 12.7 km\/l in the city and 19.1 km\/l on the highway.<\/p><li style=\"list-style-type: none\"><h5 class=\"saswp-faq-question-title \"><strong>Q. What is the real-world mileage of the Tata Altroz petrol DCT?<\/strong><\/h5><p class=\"saswp-faq-answer-text\">The Altroz DCT has returned around 10.45 km\/l in city conditions and 18.36 km\/l on highways, giving a simple combined average of approximately 14.4 km\/l.<\/p><li style=\"list-style-type: none\"><h5 class=\"saswp-faq-question-title \"><strong>Q. Which has better CNG mileage, Swift or Altroz?<\/strong><\/h5><p class=\"saswp-faq-answer-text\">The Swift CNG performs better. It returned approximately 24.35 km\/kg in the city and 31.38 km\/kg on the highway, compared with 20.56 km\/kg and 29.65 km\/kg respectively for the Altroz CNG.<\/p><li style=\"list-style-type: none\"><h5 class=\"saswp-faq-question-title \"><strong>Q. Is the Tata Altroz diesel more economical than the Swift petrol?<\/strong><\/h5><p class=\"saswp-faq-answer-text\">The Altroz diesel is economical and claims 23.64 km\/l, but the Swift petrol still has the stronger official mileage figure. The diesel&#8217;s advantage is its 200Nm torque and lower fuel price, making it attractive for frequent highway users.<\/p><li style=\"list-style-type: none\"><h5 class=\"saswp-faq-question-title \"><strong>Q. Which is cheaper to run, Swift or Altroz?<\/strong><\/h5><p class=\"saswp-faq-answer-text\">For comparable petrol and CNG versions, the Swift is generally cheaper to run. The Altroz can still make sense for buyers who prioritise diesel, a larger cabin, more luggage space or a smoother DCT automatic over maximum fuel efficiency.<\/p><\/ul><\/div>","protected":false},"excerpt":{"rendered":"<p>The Maruti Swift and Tata Altroz are two widely sought-after hatchbacks in the segment, and both have been designed while [&hellip;]<\/p>\n","protected":false},"author":38,"featured_media":538107,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"cos_headline_score":0,"cos_seo_score":0,"cos_headline_text":"Auto Draft","cos_headline_has_been_analyzed":false,"cos_last_analyzed_headline":[],"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""}},"_ayudawp_aiss_exclude":false,"_ayudawp_aiss_summary":"","_ayudawp_aiss_summary_provider":"","_ayudawp_aiss_summary_hash":"","footnotes":""},"categories":[370],"tags":[],"class_list":["post-540698","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-car-comparison"],"acf":[],"jetpack_featured_media_url":"https:\/\/www.spinny.com\/blog\/wp-content\/uploads\/2026\/08\/20250523040249_New_Tata_Altroz_Pristine_White1.avif","_links":{"self":[{"href":"https:\/\/www.spinny.com\/blog\/wp-json\/wp\/v2\/posts\/540698","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.spinny.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.spinny.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.spinny.com\/blog\/wp-json\/wp\/v2\/users\/38"}],"replies":[{"embeddable":true,"href":"https:\/\/www.spinny.com\/blog\/wp-json\/wp\/v2\/comments?post=540698"}],"version-history":[{"count":2,"href":"https:\/\/www.spinny.com\/blog\/wp-json\/wp\/v2\/posts\/540698\/revisions"}],"predecessor-version":[{"id":540702,"href":"https:\/\/www.spinny.com\/blog\/wp-json\/wp\/v2\/posts\/540698\/revisions\/540702"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.spinny.com\/blog\/wp-json\/wp\/v2\/media\/538107"}],"wp:attachment":[{"href":"https:\/\/www.spinny.com\/blog\/wp-json\/wp\/v2\/media?parent=540698"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.spinny.com\/blog\/wp-json\/wp\/v2\/categories?post=540698"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.spinny.com\/blog\/wp-json\/wp\/v2\/tags?post=540698"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
