The '''Tata Revotron engine'''<ref>{{Cite web |date=2017-09-07 |title=Revotron and Revotorq Engines |url=https://www.tatamotors.com/blog/corporate/revotron-and-revotorq-engines/ |access-date=2022-03-31 |website=Tata Motors Limited |archive-date=30 November 2021 |archive-url=https://web.archive.org/web/20211130141604/https://www.tatamotors.com/blog/corporate/revotron-and-revotorq-engines/ |url-status=dead }}</ref> is a 1.2-liter 3-cylinder [[petrol engine]]. It is produced by [[Tata Motors Passenger Vehicles|Tata Motors]] and was used in their passenger vehicles beginning in 2014.<br />
<br />
==History==<br />
The Revotron series began with a 1.2-liter, 4-cylinder turbocharged engine introduced in 2014 for the [[Tata Bolt|Bolt]] and [[Tata Zest|Zest]]. This engine featured a [[Overhead camshaft engine|single overhead cam]]<nowiki/>shaft with two valves per cylinder and multi-point [[fuel injection]]. It delivered 88 hp (65 kW) at 5,000 rpm and 100 lb⋅ft (140 N⋅m) of torque between 1,500 and 4,500 rpm. It included multiple driving modes for improved response, a smart engine control unit, an eight-holed fuel injector, a reinforced [[crankcase]], and an updated exhaust system.<br />
<br />
In 2015, Tata showcased a 1.2-liter, 3-cylinder naturally-aspirated version, later used in the [[Tata Tiago|Tiago]] and [[Tata Tigor|Tigor]]. It offered a dual overhead camshaft driven by a [[timing chain]], [[variable valve timing]], [[exhaust gas recirculation]], a variable oil pump, and four valves per cylinder with hydraulic adjusters. <br />
<br />
A turbocharged 1.2-liter, 3-cylinder variant debuted in 2017 with the [[Tata Nexon|Nexon]], adding a [[turbocharger]] and [[intercooler]]. Despite competitors using direct injection, it retained multi-point fuel injection, producing 110 hp (81 kW) and 130 lb⋅ft (170 N⋅m). <br />
<br />
A more powerful version, offering 120 hp (88 kW), arrived in 2020 with the BS6-compliant Nexon facelift, still using multi-point fuel injection. <br />
<br />
In January 2021, Tata launched a turbocharged Revotron engine for the [[Tata Altroz|Altroz]] iTurbo variant, delivering 110 hp (81 kW) and 100 lb⋅ft (140 N⋅m).<ref>{{Cite web |title=Tata Altroz iTurbo review, test drive |url=https://www.autocarindia.com/car-reviews/tata-altroz-iturbo-review-test-drive-419699 |date=31 January 2021 |first=Sergius |last=Barretto |access-date=2023-04-23 |website=Autocar India |language=en}}</ref> The lower output aimed to distinguish it from the Nexon and address fitment issues with the Nexon’s larger 6-speed manual transmission. <br />
<br />
In January 2022, Tata introduced [[Compressed natural gas|CNG]] variants for the [[Tata Tiago|Tiago]] and [[Tata Tigor|Tigor]], branded as iCNG, marking the company's first cars with this fuel option.<ref>{{Cite web |title=Tata Tiago CNG, Tigor CNG launched; prices start from Rs 6.09 lakh |url=https://www.autocarindia.com/car-news/tata-tiago-cng-tigor-cng-launched-prices-start-from-rs-609-lakh-423288 |date=19 January 2022 |first=Saptarshi |last=Mondal |access-date=2023-04-24 |website=Autocar India}}</ref> This engine produces 72.5 hp (54.1 kW) and 70 lb⋅ft (95 N⋅m) of torque, paired with a 5-speed manual gearbox, and can start directly in CNG mode, a unique feature.<ref>{{cn|date=July 2025}}</ref> The [[Tata Punch|Punch]] and Altroz later received iCNG versions.<br />
<br />
In January 2023, Tata unveiled the Altroz Racer, a sportier version with the same 120 hp (88 kW) as the Nexon, enabled by a 6-speed manual gearbox.<ref>{{Cite web |title=Tata Motors Altroz Racer Features |url=https://autoexpo.tatamotors.com/products/passenger-vehicles/altroz-racer-features.aspx |access-date=2023-04-14 |website=autoexpo.tatamotors.com |archive-date=26 November 2023 |archive-url=https://web.archive.org/web/20231126000803/https://autoexpo.tatamotors.com/products/passenger-vehicles/altroz-racer-features.aspx |url-status=dead }}</ref> Production was confirmed, potentially replacing the slower-selling iTurbo.{{Update inline|date=July 2025}}<br />
