The Jetta TDI from a Green Point of View

One of the largest causes of the pollution that contributes to global warming is fuel emissions containing carbon by vehicles. Thus, people are choosing to drive less, and walk, cycle or take public transports more. However, there are some who cannot escape driving for work purposes. Yet, the Volkswagen Jetta TDI lessens this guilt as it is known to be able to run on biodiesel. Here is a green Jetta TDI review and see if this car’s right for you.


First of all, biodiesels are basically from vegetable oil or animal fats. Their diesel form is from a chemical reaction between chemical reacting lipids with alcohol. Such forms of diesel can either be directly used with fuel-converted diesel engines, or by mixing it with petrodiesel. Biodiesel is generally cheaper than diesel and petroleum fuel.


The TDI basically uses an electronic control for the fuel injection, allowing for more power, less smoke and noise, and allow for better fuel consumption, which in a green perspective, means less pollution. The timing of the injection and its quantity is also controlled for optimized usage, while older models of VW diesel engines used mechanical versions which gave cold starts. Basically, the turbocharger on the 4-cylinder TDI models allows for faster response as compared to the older ones, and a boost in power can be done with low engine speed and extended to higher engine speed without much pressure at the exhaust flow. There is still the presence of turbo lag but it is short and unnoticeable at 0.25 seconds.



Even the exhaust gas recirculation is electronically controlled to reduce emissions of NOx. The two-stage injector nozzles are used in the TDI, thus presence of higher gradual injection pressures also means less noise and lower emissions. At the same time, its open-type combustion chamber has less heat loss during the cold, and uses lower compression ratio that reduces its noise and vibration, increasing engine durability.



Especially if you use the DSG double clutch automatic transmission with this TDI series, you are likely to save more fuel as your gear shifts are quicker than manual ones. The biggest downside you would face is its turbo lag with the DSG, though there is less lag with the manual ones. However, to date, this is probably the best environmental-friendly diesel car available. Hopefully, with this Jetta TDI review, you will find a greener form of travelling.
