Magical TSI

Magical TSI Rating  :      

When it comes to the refinement & top-end sweetness, nothing beats a petrol power plant, making it a rev happy car enthusiast’s first preference. The adrenalin rush that a smooth high revving petrol power plant offers an enthusiast can only be experienced and never expressed. Diesel mill can never kindle the same kind of enthusiasm, thanks to it, not being rev happy and feeling strained at higher RPM’s. 


DOWNSIZING is the underlying theme of TSI technology.

Downsizing normally starts with engine capacity with a simple objective of achieving higher fuel efficiencies, but with a compromised power output. With TSI, VW, however, thought just from the opposite end of the spectrum, not only does it offers superb mileage but also reduces emissions without compromising on power delivery. How does VW TSI technology works

1)      TSI engines are smaller in size with lower engine capacity. Smaller size engine has lower various frictional losses that translates into better mileage figures Vs traditionally large sized power-plant.

2)      Smaller engine size means lower weight making the vehicle lighter overall. This improves P/W ratio ultimately impacting the performance & hence efficiency in a positive way. 



TSI technology uses direct injection mechanism combined with charged compression instead of naturally aspirated petrol injection. The mechanism is operated with the help of TWINCHARGER  -  SUPERCHARGER & TURBOCHARGER.

Supercharger operates at the lower rev-range where there is need of instant torque, while the turbocharger comes into action with rising rev-range. Charged compression facilitates burning of the fuel in a highly efficient manner as compared to naturally aspirated engines. The atomization of the fuel is near perfect & every drop of the fuel burns effectively & efficiently.

Supercharger provides instant torque from the start to mid rev-range. This equips the engine with great pulling power from revs as low as 1500 rpm. Once past the low-end rev range, supercharger gets activated as and when required particularly between 2500-3500 rpm range.

Post 3500 rpm, in-line turbocharger comes into action. Being in line with the exhaust gases, it uses exhaust gases to boost the pressure, thus helping to achieve greater fuel-efficiency without sacrificing the performance.  


VW has created revolution with TSI technology. It has won laurels across the world because of its frugality and efficient nature of the invention. Some of the key advantages are:

·         Excellent drivability.

·         Strong pulling nature even from low rev-range.

·         Reduced vehicle weight.

·         Improved fuel-efficiency.

TSI proves that driving fun and fuel efficiencies can be packaged beautifully in a balanced manner. With every passing day its increasingly becoming the preferred technology world-wide.

Vitara Brezza ZDiEcoSport 1.5 DV5 MT Titanium Diesel

With the Vitara Brezza, Maruti takes teh sub4 meter battle straight to Ford Ecosport, a compact SUV which since it's launch did not have a worthy competitor. Vitara Brezza is banking on huge fan following of Maruti's badge to make a dent to Ecosport sales. And if Ford action o fcutting prices of its most popular car is any indication, it seems to have ruffled feathers in competing camp. How well Brezza stand up to Ecosport, read and decide. For us the decision is still pending.
