The 1.8 litre TSI petrol engine gives 157.8 BHP of max power and 250 Nm of torque. The 2.0 litre TDI diesel engine churns out 170 BHP power. Both the petrol and the Diesel version will be available in Manual as well as DSG Automatic Transmission option.
What is Volkswagen Bluemotion?
Bluemotion is not one technology, but it’s a terminology for a series of cars which use highly efficient technologies which make these cars eco-friendly without compromising on the performance. The technologies used in Bluemotion series of cars include:
* Aerodynamic design for less air resistance
* Automatic Start/Stop or Micro-Hybrid System
* Recuperation technology or regenerative braking
* Low rolling resistance tyres for improved fuel efficiency
* High fuel mileage with high efficiency modem engine with fine tuned MPFI and CRDI Systems
* Low emissions in exhaust
* Innovative DSG gearbox for reduced fuel consumption and better performance
What is Volkswagen DSG Gearbox System?
DSG or Dynamic Shift Gearbox by Volkswagen is a very innovative fusion of good attributes of Manual and automatic transmission technologies. Manual transmission is very efficient and results in very minimum losses and high performance, whereas conventional Automatic transmission with fluid based torque converter system are expansive and result in performance and energy loss to some extent over the manual gearboxes.
DSG gearbox with dual clutch technology picks the best of the two systems and combines them into one system which uses two dry clutched and a mechatronics controller which changes gears automatically based on the calculations done by the electronic unit which monitors various sensors. So this unit as a whole, monitors the car’s speed accelerator position and automatically changes gears according to the needs of the driver. Since the gears are changed by an intelligent unit controlling the gear shift using mechanical controllers inside the system, there are very small energy losses unlike fluid based torque converters. This results in better performance, better acceleration and better fuel mileage. In layman’s terms, its like computer changing gears on a manual transmission like mechanism.
