A recent test that was done on Volkswagen Jetta TDI has been a talk in the town of the car’s huge fans as it is said that the test is not done properly. The main question is, will the car’s engine performance reduces if it is shut down to pass the US emissions if the car gets fixed?
To get this issue clear, The Fast Lane Car tests a 2011 Jetta TDI with six-speed DSG transmission on an all-wheel-drive dyno. The sedan runs at 140 horsepower and 236 pound-feet torque. The cars goes down to 114 horsepower and 214 lb-ft at the wheels when it is ran with four wheels. But, when it is ran using two wheels the Volkswagen Jetta TDI gets 113 horsepower and 188 lb-ft. From the result, the power differences between the two are about 15 horsepower and 32 lb-ft.
With all of these being done, the test protocol and dyno are nothing like what EPA uses. The two-wheel-drive’s front wheels only are used to make the Volkswagen Jetta TDI to be on the ‘emissions testing mode’. However, the problem with the software code may be more than that.
It is hoped that with whatever is happening with the Volkswagen Jetta TDI test issue, Volkswagen will find its way to solve the issue. They really need to look into every aspect, whether the problem comes from the car, or the test itself is at fault.
