First VW Polo BlueMotion to have gasoline-fueled TSI technology; new 3-cylinder engine, 57 mpg

15 November 2014

Volkswagen is introducing its first fuel-saving BlueMotion vehicle with a gasoline-fueled TSI engine with the Polo TSI BlueMotion. (Earlier post.) Improvements to the TSI engine management system have made it possible to reduce fuel consumption by a further 0.2 liters to 4.1 l/100 km (57 mpg US) and emissions to 94 g/km CO₂.

As a result, the TSI BlueMotion is the first gasoline-fueled Polo to receive a class A label for energy efficiency and achieve top ratings for fuel consumption and CO₂ emissions in its class.

The new three-cylinder engine with a displacement of one liter delivers 70 kW / 94 hp and can reach a top speed of more than 190 km/h (188 mph).

Apart from this first use of the highly efficient engine, the fuel consumption figures were also the result of lowering the ride height and improving the aerodynamics over the radiator grille and the underbody.

Furthermore, the Polo TSI BlueMotion also benefits from reduced rolling resistance tires and longer gear ratios in the upper transmission stages. Other factors contributing to greater driving economy are the stop/start system, regenerative braking and a gear-change indicator for the driver.

A new electro-mechanical servo steering system improves steering properties. Assistance systems have also been introduced into the Polo program such as the standard Automatic Post-Collision Braking System (which automatically initiates braking after a collision) and the optional Driver Alert System, Front Assist ambient traffic monitoring system with City Emergency Braking and Adaptive Cruise Control (ACC).

The infotainment options have also been re-conceptualized, with three radio/CD systems and one radio/CD/navigation system. Depending on the version, the devices offer functions such as Bluetooth audio streaming (including cover display and touchscreen control, depending on the smart phone used), a proximity sensor (other menu details are shown when hand approaches the screen), and interfacing of the mobile phone to the vehicle’s exterior antenna by inductive coupling.

The entry price for the new Polo TSI BlueMotion is €15,925 (US$19,800).
