At Tata Motors, we invest significant resources in the development of vehicle engines that are fuel-efficient and performance-oriented.
In 2014, we unveiled the Revotron (petrol variant) and Revotorq (powered by diesel) engine family for usage in our passenger vehicles.
Both variants of the engine underwent rigorous testing before being launched for use in passenger vehicles. Our Tiago hatchback, which is available in both engine variants, completed the Geared for Great Challenge - a 50,000 km endurance test under high-stress conditions. The two variants averaged 120kmph during the 18-day, non-stop, high-speed drive.
- Revotron Engines
Tata Motors’ indigenously developed Revotron 1.2T engine is India’s very first 1.2L turbocharged, multipoint, fuel Injection petrol engine. It is designed to deliver maximum fuel economy while providing a zippy driving experience. A unique feature of this engine is its multi-drive mode, which is the first in its segment. The ability to switch between Eco, Sport, and City modes enables you to change the performance settings of your Tata car as per your requirement. Switching to the Eco mode optimizes the Revotron 1.2T engine’s power and torque, and is suitable for achieving maximum fuel economy. The engine’s output is maximised in the Sport mode, making it ideal for performance driving. In the City mode, Revotron 1.2T engine increases its output till it balances performance and fuel economy. These three driving modes are supported by a cutting-edge engine management system (EMS). A stiffened crank case helps minimise engine vibration, noise, and harshness, while a smart electronic control unit enables precise control. Revotron 1.2T engine, which received critical acclaim, was globally benchmarked for advanced on-road performance. AVL Austria, which is the world's largest independent engineering company for development of powertrain systems, optimised the design of Revotron 1.2T engine. Bosch, INA, and Honeywell were our key technology partners in the development of this engine. This ultra-quiet engine is the driving force behind our Tiago and Bolt hatchbacks, as well as Tigor and Zest compact sedans, which were well-received by critics and consumers alike. The Revotron 1.2T engine will also feature in the Tata Nexon sub-compact SUV.
- Revotorq Engines
Tata Motors' Revotorq 1.05L diesel engine has been designed to withstand extreme performance, while simultaneously providing a unique driving experience. Like the petrol variant, this engine has been crafted to maximise fuel economy, while delivering a highly-refined road performance. This engine has also been globally benchmarked, based on parameters such as performance, refinement, and economy. It also offers the multi-drive mode, which is supported by a state-of-the-art EMS. Making its debut with our Tiago hatchback, Tata Motors' Revotorq 1.05L diesel engine is also powering the Tigor compact sedan. The diesel variant of the Tata Nexon sub-compact SUV will also come fitted with this engine.
These advanced engines will be featured prominently in several of our current and upcoming cars.
