TATA motors a subsidiary of TATA group, has announced the new 1.2 petrol engine, the first to be developed in-house for 15 years; and said this was only the first of a range of engines on the design board.  

The company announced the launch of this new series of Revotron engines, with Revotron 1.2 litre turbo charged petrol engine as the first of the family. The Revotron engine family comprises of 3 and 4 cylinder petrol engines. 

This first release engine Revotron 1.2T is a 1.2 litre, 4 cylinder, 8 valve, inter cooled, turbocharged, multi-point fuel injection model. This engine produces 85PS at 5000 RPM ad 140Nm torque at about 1750 to 3500 RPM. TATA motors have built a engine that would enhance the driveability.  The new engine will be less burden on your pockets with its fuel economy. The focus seems to be a budget friendly engine than a pure performance . the engine has multiple modes for driving including better throttle response, ECU, 8 hole fuel injector and new catalytic converter.

Announcing the launch, Mr. Ranjit Yadav, President, Passenger Vehicle Business Unit, Tata Motors said: "With the launch of REVOTRON 1.2T, Tata Motors passenger vehicles business is making a strategic shift towards a more complete portfolio. The name itself, an amalgamation of Revolution and the French word "tronel", meaning "balance", conveys the essence of this engine brand that uses key technological advances to revolutionize and balance great driving maneuverability, without compromising on power or fuel efficiency. We are enhancing our portfolio with the next generation petrol engines - REVOTRON series".

''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, feeding the vehicle with raw power continuously. It's multi-drive mode, coupled with a superior throttle response, advanced catalytic converter with reduced toxic emissions and Smart ECU (Electronic Control Unit) with various innovative strategies, ensure a superlative performance on Indian roads,'' Tata Motors said in a release.

The engine is light-weight and powerful, with a stiffened crankcase that minimises noise, vibration and harshness (NVH) for a refined output. It 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.

The engine also comes with a select-able multi-drive mode and uses low-viscosity, fuel efficient engine oil. An optimised water-jacket and head gasket, using computational fluid dynamics (CFD) technology ensures 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.

Tata Motors, which has seen sales plunge this year amid a wider slowdown in the auto market, generates the bulk of its passenger vehicle sales through diesel-powered vehicles.

It was said that Tata Motors took about 3 years instead of 4 as per industry to develop the new engines and it's expected that the engines will make it to all of Tata's cars - from Nano to sedans.
