Snapshot: Tata Motors has developed a new 1.2 liter turbo petrol engine, which in Mr Karl Slym’s opinion will be a game changer in the B-Segment hatchback space. New details have emerged about this engine, which reportedly will be tuned for outstanding fuel efficiency. 

The Tata Falcon 4 (upgraded Vista) hatchback and the Falcon 5 (Manza based compact sedan) will get a new 1.2 liter petrol engine. The turbo petrol motor, based on Tata Motors’ 1.2 liter XETA petrol engine, will reportedly output 80 Bhp of peak power.

While the more crucial, torque output of this motor remains unknown, expect it to be well above the 100 Nm mark that the stock XETA motor manages to pump out. A torque output in the whereabouts of 140 Nm is a likely figure considering the addition of a turbocharger.

AutocarIndia reports that the new turbo petrol engine from Tata Motors will focus on fuel efficiency rather than outright performance. The specifications surrounding this engine seem to support the fuel efficiency focus. The 4 cylinder engine will have a 2 valve/cylinder head, a rarity in today’s world of DOHC-4 valve/cylinder engines.

The engine is said to feature a lower weight, new cylinder head, and better stiffness and balance. The TA65 gearbox is also likely to see improvements in shift quality. Incidentally, Tata Motors gave the TA65 gearbox a once over for the refreshed Indica eV2/Indigo eCS models as recently as mid 2013.

By capping the 1.2 liter turbo petrol engine’s output at 80 Bhp, Tata Motors seems to be holding back a more powerful version of this engine, with a 4 valve/cylinder-DOHC layout, for future use. As emission norms get tighter and with car buyers demanding better fuel efficiency from petrol engine, turbo charging is the logical next step for car makers.

While the performance oriented Volkswagen Polo GT TSI spawned the turbo petrol hatchback segment in India, the Tata Falcon 4 and Falcon 5 models could open the floodgates for big volume turbo petrol cars in the budget segments.
