Wolfsburg/Geneva,March 2012. The new Polo BlueGT stands out in

its ability to combine superior dynamic performance with extreme

fuel-efficiency. The technical highlight of the progressive compactcar is the cylinder deactivation system, which is being introduced for

the first time in a Volkswagen also known as active cylinder manage-

ment or ACT. The system was realised with the new 1.4-litre TSI of the

Polo BlueGT. The torque-strong TSI develops a power output of 103 kW /

140 PS, yet has a combined fuel consumption of just 4.7 l/100 km/h*

(equivalent to 108 g/km* CO2). If the Polo BlueGT is ordered with the

optional 7-speed dual clutch gearbox (DSG), fuel consumption drops

further to 4.5 l/100 km* and, bear in mind, this is a petrol, not a diesel

(105 g/km* CO2). Nonetheless, this car, with a top speed of 210 km/h, ac-

celerates to 100 km/h in just 7.9 seconds. This uncommon coexistence

of efficiency and dynamic performance is enabled by the systematic

interplay of ACT, downsizing (reduced engine displacement plus di-

rect injection and charging) and BlueMotion Technology (Stop/Start

system, battery regeneration). As such, the Polo BlueGT closes the gap

between the Polo 1.2 TSI (77 kW / 105 PS) and the Polo GTI (132 kW /

180 PS). The new car will already on the market in July.

engines and the EA288 series diesel engines, which are also new, are

technological pillars of the future Modular Transverse Matrix (MQB).

One property shared by all of these engines is an identical mounting

position in the car and indeed across vehicle classes and brands.

Fuel savings by ACT. Even before the MQB is introduced, Polo

BlueGT buyers will get to enjoy the new high-tech TSI with cylinderdeactivation. Volkswagen is the first carmaker to introduce active

cylinder management as a fuel-saving technology in smaller engines

they were previously only known in larger eight or twelve cylinder

units. Shutting down the second and third cylinders under low and

medium load states reduces fuel consumption in the EU driving cycle

by about 0.4 l/100 km. In constant speed driving at 50 km/h in third or

fourth gear, fuel savings are as much as one litre per 100 km. But even

when driving at 70 km/h in fifth gear, fuel consumption is stil l reduced

by 0.7 l/100 km.

ACTmode ofoperation.ACT becomes active at engine speeds from

1,250 to 4,000 rpm, and at torque outputs from 25 to approx. 100 Nm

a broad swath of the operating map that includes nearly 70 per cent

of all driving states in the EU driving cycle! When the driver presses

the accelerator pedal, the two cylinders are imperceptibly reactivated.

The high efficiency certainly does not come at the price of a high level

of smooth engine running: even with two cylinders, the excellently

balanced 1.4 TSI of the Polo BlueGT runs just as quietly with as little

vibration as it does when all four combustion chambers are active.

All mechanical switchover actions are completed within one half of a

camshaft revolution; this only takes between 13 and 36 milliseconds,

depending on engine speed. The transitions are smoothed by

supporting interventions to the ignition and throttle valve. Ingenious:

thanks to an accelerator pedal sensor and intelligent monitoring

software, the system can also detect non-uniform driving profiles

such as while driving through traffic or in a sporty manner when driving

on a country road. In such cases, cylinder shutoff is disabled. The driver

is informed whether two or four cylinders are active by an indication

in the multifunction display located between the speedometer and

tachometer.

ACT camshaft adjustment. To further reduce emission and fuel

consumption values and improve torque in the lower engine speed

range, the intake camshaft was designed to be adjustable over a range

of 50 degree crank angle on all EA211 engines; in the 1.4 TSI of the Polo

BlueGT, an exhaust camshaft adjuster is added. It adjusts to the desired

spread of control times, thereby ensuring more spontaneous response

from low revs; at the same time, it also improves torque at high revs.

Exter ior of the Polo BlueGT. The new Volkswagen is clearly

distinguished both inside and out. From the outside, it is the new

17-inch alloy wheels with spoke styling, GT signatures at the front and

rear (and additional BLUEMOTION at the rear) and new tailpipe trim

that are identifying characteristics of the Polo BlueGT. In addition,

numerous standard features were adapted from the Polo GTI or the

Polo BlueMotion. GTI features are the rear spoiler, rear bumper with

diffuser, front bumper and fog lights including daytime running lights.

BlueMotion elements are the side sills and the front rain channels

(outside on the windscreen). The Polo BlueGT is also upgraded by a

black painted radiator grille, R-line ventilation screen in the bumper

and black door mirrors. Having a positive effect on aerodynamics are

the Polos 15 mm lower ride height and special underbody trim.

Interior of the Polo BlueGT. Interior features were upgraded by

extended functionality of the multifunction display (ACT message

and tyre pressure), the GTI instruments, a cruise control system, black

roofliner and black pillar trim in GTI style, vanity and interior lights

tuned to match, a leather-trimmed sport steering wheel with BlueGT

emblem, sport seats in front with newly designed trim (fabric type and

colour) as well as various chrome surrounds.
