Volkswagen Passat GTE (2015)

Equipment - high-tech features and GTE design

The Passat GTE is an independent equipment line. On the one hand, its standard equipment includes many features also available in other models of the range, either as an option or without extra charge, depending on the equipment version: LED headlights (for dipped beam and main beam), Driver Alert System, Automatic Post-Collision Braking system, Front Assist ambient monitoring system including City Emergency Braking function, rain sensor, the ParkPilot for the front and rear, chrome strips on the side windows and comfort seats in the front. On the other hand, as a high-tech flagship in terms of drive technology, the model features several unique elements and equipment upgrades inside which distinguish the Passat GTE from the rest of the range.

Exterior

In the upper section of the front end, the Passat GTE can be recognised by a specific chrome radiator grille unit with additional blue line. The front bumper was also redesigned, and distinctive here are the striking cross panels in the lower air inlet and the C-shaped LED daytime running light. The LED modules integrated directly in the bumper have advanced in the Passat GTE to an unmistakable and charismatic signature of the plug-in hybrid. The "C"-shaped LED daytime running light and the blue line in the radiator grille unit are stylistic devices purposefully deployed by Design: blue is the Volkswagen "e-mobility colour" and in conjunction with the C-shaped daytime running light, it constitutes an identifying feature of all Volkswagen's electric and plug-in hybrid models. When viewed from the side, 17-inch "Astana" alloy wheels identify the Passat GTE as a plug-in hybrid.

Interior

The interior was likewise fine-tuned for the new drive system. With a menu matrix for the functions and displays related to the drive system, the engineers and interface designers at Volkswagen TE (Technical Development Centre) tailored features such as the standard "Composition Media" infotainment system and the instrument cluster (with power meter) for the plug-in hybrid drive. In addition, the innovative Active Info Display with specific displays will be also available as an option for the Passat GTE. Standard details such as the blue ambient lighting, leather-trimmed multifunction steering wheel with blue decorative stitching, GTE-specific gear knob with blue stitching and seats covered in "Sevilla" cloth with a blue basic structure have also been especially configured to the Passat GTE. Furthermore, the interior was enhanced by the "Waves" design (aluminium look) and "Piano Black" (high-gloss black) as well as a GTE logo in front of the gear shift gate.

Controlling functions via app

The owner of the new Passat GTE can make use of the "CAR-NET e-Remote" app, by which the charging of the battery, for instance, can be started via smartphone. Likewise, all climate control functions can be activated via the smartphone. In addition, information on the vehicle status, state of charge of the battery, recent driving data or last parking position can be queried. It is also possible to check whether the doors are closed and the lights turned off.

Instruments - specific displays of the Passat GTE

The new Passat GTE will be launched with the high-resolution 6.5-inch display of the standard "Composition Media" infotainment system. Optional: the "Discover Media" (also with a 6.5-inch display) and "Discover Pro" (with an 8.0-inch display) radio-navigation systems. Both devices feature numerous additional functions in the Passat GTE. They include a "range monitor", an "energy flow indicator", "zero-emission statistics", "e-manager" and - when the optional navigation system is installed - the "360° range" feature.

• Range monitor: depicts the momentary electric driving range of the Passat GTE; the additional range potential that can be achieved by turning off auxiliary consumers that might be in use is also shown.
• Energy flow indicator: this indicator utilises animated graphics to depict the energy flow when accelerating (blue arrows) as well as braking, i.e. regenerative braking (green arrows).
• e-Manager: up to three departure and charging times can be programmed here, and heating or cooling of the interior can be activated via the stationary air conditioning, which comes as a standard feature.
• 360° range: the driving range in "E-Mode" is shown by the so-called 360° zone on the map of the surrounding area. The highlighted zone depicts the one-way electric driving range of the car. Charging stations can be displayed and used in route calculation.

Power meter is central instrument

On the left side of the instrument cluster the Passat GTE's power meter supplements the tachometer and shows information such as whether the high-voltage battery is being charged by regeneration or whether - and how much - energy is being consumed. The speedometer is still on the right side. A colour display (multifunction display Premium), which is located between the power meter and speedometer, continually displays the electric driving range and the momentary operating mode. In a separate LED field in the lower segment of the multifunction display, the "READY" message also appears after starting the e-motor, indicating that the car is ready to be driven. This is done because the electric motor cannot be heard when the car is stopped.

Active Info Display

Volkswagen is offering an instrument cluster that has been designed as a full interactive display in the new Passat GTE as an option: the Active Info Display. All instruments - thus also the specific displays in the Passat GTE - are implemented virtually by software. Navigation information can be shown in 2-D or 3-D views on a 12.3-inch display. Its resolution of 1,440 x 540 pixels enables extremely precise, high-quality graphics and interactive display of all details. Take the Navigation mode, for instance: here the speedometer and tachometer are relocated to the sides to make more room for the map display. Information on driving, navigation and assistance functions can be integrated into the graphic areas of the speedometer and tachometer as needed. Data that is displayed on the centre console via the infotainment system, such as phone contact pages or CD covers, can also be shown in the Active Info Display in the Passat. In fact, the driver can find all information relevant to driving in his direct field of view. As described above, he can pull up important data he needs according to the situation at hand and then use it in an individually selected display.

Drive system - with zero emissions whenever possible

As outlined above, Volkswagen uses a turbocharged direct petrol injection engine (1.4 TSI) and a three-phase permanent magnet synchronous motor as electric motor to power the Passat GTE. Like a turbine, the e-motor revs up from a standstill and provides a maximum torque of 330 Nm. The electric motor is supplied by the lithium-ion high-voltage battery; the battery's energy capacity amounts to 9.9 kWh. The gearbox that Volkswagen uses here is an automatic 6-speed DSG with three clutches (dual clutch plus disengagement clutch) that was specially developed for hybrid use. Whenever possible, the disengagement clutch disengages the TSI from the driven front axle and shuts it off - such as in phases of "coasting"; in this case, the Passat GTE makes use of the car's kinetic energy and coasts without any added propulsive power. Volkswagen integrated the electric motor into the gearbox housing. Additional components of the hybrid drive include the power electronics (converts DC power from the battery to AC power for the electric motor) and a charger. An electro-mechanical brake servo and an electric air conditioning compressor also ensure optimal and energy-efficient operation of the brakes and air conditioner in "E-Mode".

Operating modes

The Passat GTE can be driven in four different modes, and which one to choose is very intuitive. "E-Mode", "Hybrid", "Battery Charge" and "GTE". The driver can always see which mode is active on the multifunction display of the instrument cluster.

Starting in the "E-Mode"

Upon starting the car, the Passat GTE drives automatically in the "E-Mode" (except when the battery is not sufficiently charged or the outside temperature is very low, in which case the TSI takes over immediately). When a minimum charge level of the battery has been reached or when there is very high demand for power, the drive system automatically switches over to the "Hybrid" mode. In this state, "E-Mode" is deactivated, and the Passat GTE now behaves like a classic full hybrid vehicle that charges the battery regeneratively during deceleration and automatically uses the TSI and/or electric motor, depending on the driving situation. The charge state of the battery is maintained at a constant level in this mode. By pressing the "E-Mode" button (to the left of the gear knob), the driver can manually switch to "E-Mode." This button opens simultaneously a selection window in the infotainment system, in which the three "E-Mode", "Hybrid" and "Battery Charge" modes can be directly selected.

"Battery Charge" via menu

In addition to the "E-Mode" and "Hybrid" modes, you can set another mode via the infotainment system menu, as described: "Battery Charge" (charge the battery). In this mode, the high-voltage battery is charged during the drive.

Sporty in the "GTE" mode

By pressing the "GTE" button (also to the left of the gear knob), the driver can switch to "GTE" mode which activates the very sporty nature of the agile Passat GTE. The driver (and all passengers) notice the following: The characteristics of the accelerator pedal, gearbox and steering are made sportier. In connection with optional DCC, the chassis is firmer. The tuning of the TSI is also more performance oriented. In addition, in the "GTE" mode the TSI and electric motor work together, in what is known as "boosting", to make the full system power and the maximum system torque available.

Charging the battery

There are two different ways to charge the battery in the Passat GTE via the charging socket in the radiator grille. First: the standard charging cable is plugged into a 230 volt mains electrical socket. The battery is then charged by alternating current (AC) from the mains at a power level of 2.3 kW. From completely flat, it can be fully charged (100 per cent battery charge level) in four hours and 15 minutes. Second: Volkswagen offers an optional wall box for a garage or carport which charges at a power level of 3.6 kW. Using this method, the battery is fully charged after only two hours and 30 minutes. Like the wall box, there are also public charging stations that "refuel" electric cars at a power level of 3.6 kW.
