Cylinder Deactivation Added to 1.4-Liter TSI Engine

The EA211 series 1.4-liter inline-four engine powering the Polo BlueGT is the first in its class of small engines to feature cylinder deactivation. This system achieves excellent environmental performance with a European fuel consumption of 4.7 L/100 km and CO2 emissions of 108 g/km. With the optional 7-speed DSG, fuel economy improves further to 4.5 L/100 km (approximately 22.2 km/L), with CO2 emissions of 105 g/km. Despite this high level of environmental performance, the engine delivers a robust driving capability with a maximum output of 103 kW, a peak torque of 140 Nm, a top speed of 210 km/h, and 0-100 km/h acceleration in 7.9 seconds. In terms of specifications, this model will fill the gap between the existing 1.2 TSI (77 kW/105 ps) and the GTI (132 kW/180 ps).

Active Cylinder Technology

The cylinder deactivation system (ACT), the most distinctive feature of the Polo BlueGT, operates under conditions where the engine speed is between 1250 and 4000 rpm and torque is between 25 and 100 Nm. The transition between deactivated and active states is completed within one and a half camshaft rotations, approximately 13 to 36 milliseconds, during which the second and third cylinders are deactivated among the four cylinders.

Volkswagen states that this deactivation range covers approximately 70% of typical driving situations in the EU. The implementation of ACT results in an average fuel economy improvement of 0.4 L/100 km. During constant speed driving at around 50 km/h in third or fourth gear, it achieves a fuel saving of 1 L/100 km, and at 70 km/h in fifth gear, it offers a saving of 0.7 L/100 km. Furthermore, to enhance fuel efficiency and low-end torque, the EA211 engine is equipped with camshaft control on the intake side capable of over 50 degrees of adjustment. The Polo BlueGT additionally features an angle adjustment function on the exhaust camshaft.

The exterior features a rear spoiler inherited from the Polo GTI, a rear bumper with a diffuser, and a front bumper with fog lights and daytime running lights. Additionally, the BlueGT is distinguished by unique front and rear badges and new tailpipes.

Deliveries of the Polo BlueGT are scheduled to begin in Germany in July, with no current plans for introduction in Japan.
