Tata Motors launches REVOTRON family of next-generation gasoline engines

Tata Motors launched its REVOTRON Series of next-generation gasoline engines for the passenger vehicle market in India. The first engine in the new series, which will include 3- and 4-cylinder models, is the 1.2-liter Turbocharged Intercooled Multi-point Fuel Injected (MPFi) Petrol Engine, REVOTRON 1.2T.

Tata Motors developed the REVOTRON Series with inputs from global players in the areas of combustion, boosting, friction and calibration. Tata Motors worked closely with global engine consultant AVL and key technology partners such as Bosch, Honeywell, Mahle and INA for the new engine series. The engine has been manufactured to be light on weight and low on friction, delivering high performance and fuel economy.

The engine is equipped with a HighBoost Turbo-Charger delivering 84 hp @ 5000 RPM & 140 N·m @ 1750-3500 RPM. The modern water-cooled turbo-charger, with its low inertia wheel, provides a faster response for a flat, seamless segment-highest torque density, which is kicked in at the lowest RPM and delivered over a wide range of revolutions.

The engine features a stiffened crankcase that minimizes Noise, Vibration and Harshness (NVH) for a more refined output. The engine is refined with tuned intake and exhaust system for improved combustion noise that is further reduced with silent-steel oil pan and lower auxiliary system noise. Enhanced with Smart ECU for precise control, the engine is powered by wire technology for a smooth and responsive drive experience.

An optimized water-jacket and head gasket, developed using Computational Fluid Dynamics (CFD) technology, enables efficient combustion and reduces thermal inertia. In addition, the engine has been incorporated with an 8-hole fuel injector for superior efficiency and assisted by innovative calibration strategies.



Will an ultra light weight 600 cc 2 cyls compact version for PHEVs be next?

Coupled with appropriate light weight generator and mass produce in India, it could make future PHEVs more competitive?


Several companies have small turbo engines. Tata seems to be able to do these things at a lower price point. If the sales volume for PHEV is price dependent, they have a chance.
