Audi has just unveiled its completely redesigned 1.8 Liter TFSI turbo petrol engine that will power the upcoming Audi A5 Sedan. This engine is also known as the 1.8 TSI and is used in India in a bunch of cars like the Audi A4 Sedan, the Skoda Laura and the Skoda Superb. Now, Audi has redesigned in this engine totally to produce more power and torque for starters.
That isn’t all, the 1.8 TFSI engine is also a lot more fuel efficient that the previous iteration, which is something that is the need of the day considering the rapid decline in petrol car sales due to high petrol prices, at least in a country like India. The new 1.8 TFSI engine, which uses direct injection technology and turbocharging, produces 170Bhp and 320 Nm, a 10 Bhp and whopping 70 Nm increase from the previous iteration.
The increase in torque is much more telling as the steep increase means fewer gear changes, which translates into better fuel economy and a much more driveable car, this apart from the turbo kick every time you floor the go pedal. Audi claims that the new engine is capable of delivering a superb 17.5 KMPL, which is simply terrific for an engine this powerful.
Along with the increase in fuel economy, tailpipe CO2 emissions too see a fall to 134 grams/KM, making this engine capable of meeting Euro 6 emissions, kicking in from 2015. The higher power and torque is majorly due to improving the combustion behavior of the engine through a slew of changes like higher pressure at which the direct injection system works, which has been increased from 150 to 200 BAR. Also, the valve timing has been suitably altered for more efficient combustion.
Now, how is all of this relevant to India considering the fact that this engine is said to be used first in the Audi A5 Sedan, one which might not see an Indian launch anytime too soon? As we mentioned above, the previous iteration of the 1.8 TFSI unit already does duty in a number of Volkswagen group cars in India like the Skodas and Audis of this world.
Therefore it is only a matter of time before this engine will find its way into other Volkswagen group cars like Skoda and hence, will arrive into India sooner than later as the demand for more fuel efficient turbo petrol engines rise. Are we at the cusp of the rise of the turbo petrol engine? You bet!
