Its calculated combined average was 9.99 kmpl.<\/p>\n\n\n\n<p>CarWale tested the diesel automatic at 12.3 kmpl in the city and 16.2 kmpl on the highway. Its combined average was 13.27 kmpl.<\/p>\n\n\n\n<p>Autocar India recorded 11.53 kmpl in the city and 14.56 kmpl on the highway from the diesel automatic.

Its lower output makes it suitable for relaxed city driving and buyers prioritising a lower purchase price.<\/p>\n\n\n\n<p>The six-speed manual gives drivers direct control over gear selection. It should be the most economical petrol option when driven smoothly.<\/p>\n\n\n\n<p>The seven-speed DCT removes clutch operation in traffic. However, low-speed creeping and repeated acceleration can increase fuel consumption.<\/p>\n\n\n\n<p>The claimed figures of 17.4 kmpl for the manual and 16.9 kmpl for the DCT are significantly higher than the turbo-petrol\u2019s tested results. Direct independent city and highway tests are still needed before firm real-world figures can be assigned.<\/p>\n\n\n\n<p>The naturally aspirated engine may require more throttle when the SUV carries five occupants or climbs steep inclines. This can reduce mileage despite its lower power output.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"turbo-petrol-automatic\"><strong>Turbo-Petrol Automatic<\/strong><\/h3>\n\n\n\n<p>The turbo-petrol is the performance-oriented Sierra.<\/p>\n\n\n\n<p>Its 160 PS output and 255 Nm torque provide faster acceleration and stronger overtaking performance. The six-speed torque-converter gearbox is also smoother than many dual-clutch units during slow urban driving.<\/p>\n\n\n\n<p>Performance comes with higher fuel consumption. The tested city figure of 8.95 kmpl is around 41 percent below its 15.3 kmpl claimed figure.<\/p>\n\n\n\n<p>The highway result improves to 13.12 kmpl. However, it remains lower than the Sierra diesel automatic.<\/p>\n\n\n\n<p>The turbo-petrol suits buyers who value refinement and performance more than minimum fuel expenses.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"tata-sierra-diesel-real-world-mileage\"><strong>Tata Sierra Diesel Real-World Mileage<\/strong><\/h2>\n\n\n\n<p>The diesel is the strongest Sierra choice for high annual usage.<\/p>\n\n\n\n<p>Its low-speed torque allows the SUV to move with less accelerator input. This is useful when carrying passengers, luggage, or travelling through hilly areas.<\/p>\n\n\n\n<p>The diesel automatic returned between 11.53 and 12.3 kmpl in two independent city tests. Highway mileage ranged from 14.56 to 16.2 kmpl.<\/p>\n\n\n\n<p>These figures are lower than the claimed 19.22 kmpl. However, they remain considerably better than the turbo-petrol automatic\u2019s results.<\/p>\n\n\n\n<p>The diesel manual has the highest listed mileage at 21.26 kmpl. It should appeal to frequent highway users who do not require an automatic. Current owner-reported figures listed by Autocar India average approximately 15.84 kmpl, although owner reports are not equivalent to a controlled test.<\/p>\n\n\n\n<p>Diesel may not suit buyers who only complete short neighbourhood journeys. Regular longer drives allow the engine and emission-control system to reach normal operating temperatures.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"tata-sierra-city-mileage-comparison\"><strong>Tata Sierra City Mileage Comparison<\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"naturally-aspirated-petrol-in-the-city\"><strong>Naturally Aspirated Petrol in the City<\/strong><\/h3>\n\n\n\n<p>The naturally aspirated petrol should be adequate for routine city use.<\/p>\n\n\n\n<p>The manual offers lower acquisition cost and greater control. The DCT is more convenient in congestion but may consume more fuel during frequent low-speed movement.<\/p>\n\n\n\n<p>Drivers should expect actual mileage below the listed 16.9 to 17.4 kmpl figures. Severe traffic, short trips, and air-conditioning can widen the difference.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"turbo-petrol-in-the-city\"><strong>Turbo-Petrol in the City<\/strong><\/h3>\n\n\n\n<p>The turbo-petrol automatic delivered 8.95 kmpl during city testing.<\/p>\n\n\n\n<p>Its strong performance can encourage heavier acceleration. The engine also consumes more fuel when repeatedly building boost between traffic signals.<\/p>\n\n\n\n<p>Buyers driving through severe congestion should budget for single-digit mileage in many conditions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"diesel-in-the-city\"><strong>Diesel in the City<\/strong><\/h3>\n\n\n\n<p>The diesel automatic delivered between 11.53 and 12.3 kmpl in independent city tests.<\/p>\n\n\n\n<p>Its stronger torque makes low-speed movement easier. Less accelerator input is required to maintain traffic speed.<\/p>\n\n\n\n<p>The diesel provides a clear cost advantage for drivers covering substantial daily distances. It is less attractive for occasional short journeys.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"what-affects-tata-sierra-city-mileage\"><strong>What Affects Tata Sierra City Mileage?<\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"traffic-density\"><strong>Traffic Density<\/strong><\/h3>\n\n\n\n<p>Repeated braking and acceleration increase fuel consumption. Extended idling also lowers the displayed average.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"driving-style\"><strong>Driving Style<\/strong><\/h3>\n\n\n\n<p>Rapid acceleration causes the turbo-petrol to consume significantly more fuel.

However, overtaking with passengers may require downshifting.<\/p>\n\n\n\n<p>The engine will work harder than the turbo-petrol or diesel during inclines. Frequent high engine speeds can reduce its mileage advantage.<\/p>\n\n\n\n<p>It suits buyers whose highway use is occasional and unhurried.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"turbo-petrol-on-highways\"><strong>Turbo-Petrol on Highways<\/strong><\/h3>\n\n\n\n<p>The turbo-petrol automatic returned 13.12 kmpl during CarWale\u2019s highway test.<\/p>\n\n\n\n<p>Its higher torque makes overtaking easier. Maintaining a steady speed can keep fuel consumption under control.<\/p>\n\n\n\n<p>Frequent rapid acceleration or sustained high speeds will reduce efficiency quickly.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"diesel-on-highways\"><strong>Diesel on Highways<\/strong><\/h3>\n\n\n\n<p>The diesel automatic delivered between 14.56 and 16.2 kmpl during independent highway tests.<\/p>\n\n\n\n<p>Its strong torque reduces the need for frequent gearbox downshifts. This makes it the most suitable Sierra for regular intercity travel.<\/p>\n\n\n\n<p>The diesel manual should provide the greatest highway range. Its listed claimed mileage is 21.26 kmpl.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"tata-sierra-driving-range\"><strong>Tata Sierra Driving Range<\/strong><\/h2>\n\n\n\n<p>The Tata Sierra has a 50-litre fuel tank.<\/p>\n\n\n\n<p>Using the tested combined mileage:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The turbo-petrol automatic could theoretically cover around 500 km.<\/li>\n\n\n\n<li>The diesel automatic could theoretically cover around 654 to 664 km.<\/li>\n<\/ul>\n\n\n\n<p>Using the tested highway mileage:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The turbo-petrol automatic could theoretically cover around 656 km.<\/li>\n\n\n\n<li>The diesel automatic could theoretically cover around 728 to 810 km.<\/li>\n<\/ul>\n\n\n\n<p>Actual usable range will be lower.

Reserve Sport mode for situations requiring quicker response.<\/p>\n\n\n\n<p>Avoid making the engine struggle in a high gear. Downshift when required.<\/p>\n\n\n\n<p>Use light accelerator inputs with the automatic gearboxes. This encourages earlier upshifts.<\/p>\n\n\n\n<p>Check tyre pressure regularly, especially before carrying a full passenger load.<\/p>\n\n\n\n<p>Remove unnecessary luggage from the boot.<\/p>\n\n\n\n<p>Avoid extended idling. Switch off the engine during long waits when safe.<\/p>\n\n\n\n<p>Follow Tata\u2019s recommended maintenance schedule. Dirty filters and incorrect wheel alignment can reduce efficiency.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"summary\"><strong>Summary<\/strong><\/h2>\n\n\n\n<p>The Tata Sierra offers naturally aspirated petrol, turbo-petrol, and diesel engines.<\/p>\n\n\n\n<p>Listed mileage ranges from 15.3 kmpl for the turbo-petrol automatic to 21.26 kmpl for the diesel manual.<\/p>\n\n\n\n<p>The turbo-petrol automatic returned 8.95 kmpl in the city and 13.12 kmpl on the highway during independent testing.<\/p>\n\n\n\n<p>The diesel automatic returned between 11.53 and 12.3 kmpl in the city.
