Detroit Auto Show 2012 – Volkswagen shows commitment to hybrid and electric mobility
World premieres of the Jetta Hybrid and the E-Bugster concept car
“Volkswagen not only stands for emotion and driving fun, but also for sustainable and responsible mobility.”
Wolfsburg / Detroit, 09 January 2012 – Volkswagen is kicking off the year 2012 with two world premieres, both of which showcase innovative design and technological progress: the new Jetta Hybrid is powered by a high-tech petrol engine and a zero emissions electric motor. And the E-Bugster concept demonstrates that the sportiness of the Beetle can also be realized with an electric drive.
In the Jetta, propulsion is handled by a combination of a four-cylinder 1.4 TSI (110 kW / 150 PS), a 7-speed DSG and an electric motor (20 kW). A unique feature here: at the press of a button, the Jetta Hybrid can be driven in a pure electric mode up to a speed of 70 km/h and a distance of two kilometres – with zero emissions. The Jetta Hybrid is now the second Volkswagen, after the Touareg, to have a drive module consisting of both a petrol engine and an electric motor under the bonnet.
The E-Bugster radiates a very special dynamism from all viewing angles with flush windows, a low roof and 20-inch wheels. The two-seat speedster draws its power from a lithium-ion battery. The 80 kg light electric motor with a power output of 85 kW enables a minimum driving range of 180 km – with zero emissions. In addition, the E-Bugster has a system for recovering braking energy. As soon as the driver’s foot leaves the accelerator pedal or brakes, the car’s kinetic energy is converted to electricity, which is stored in the battery. This extends the car’s driving range.
“The new Jetta Hybrid and the E-Bugster are showing once again that Volkswagen not only stands for emotion and driving fun, but also for sustainable and responsible mobility,” explains Dr. Ulrich Hackenberg, Head of Development for the Volkswagen brand.
World premiere of the E-Bugster North American International Auto Show, Detroit
World premiere of the E-Bugster – an electrified Beetle!
- Beetle concept car is powered by an 85 kW E-motor
- Zero emissions vehicle was conceptualized as two-seat speedster
Wolfsburg / Detroit, January 2012. For many people, it is the most
congenial car of a new era: The Beetle! The successor to an automotive
icon. Its world premiere took place in April 2011 in New York, and
it was launched on the market in October. Since then, the sportiest
Beetle ever has been ready to perform – with up to 147 kW / 200 PS in
power. And because all Beetle versions are tuned for agility, versions
with less horsepower (from 125 kW / 170 PS in America, from 77 kW /
105 PS in Europe) are still simply fun to drive – mile for mile, kilometre
for kilometre. Now, at the North American International Auto Show
in Detroit, Volkswagen is showing that this sportiness can also be
transferred to a Beetle with pure electric drive. The E-Bugster was
specially designed for this mission: a two-seat Beetle speedster, 85 kW
in power, 0 to 60 mph in 10.9 seconds, with zero emissions yet the
sharpest of proportions.
Blue-e-Motion for a clean future
The central electric module of the E-Bugster has an innovative design;
it weighs just 80 kg. The energy for powering the electric motor is
stored in a lithium-ion battery whose modules are housed in a spacesaving
location behind the front seats. The battery’s energy capacity
of 28.3 kWh enables a range of at least 110 miles (180 km) in the urban
world. And even in an enormous country like the USA, for the majority
of commuters this distance is sufficient to drive to their workplaces
and return home. Since the Volkswagen has a quick charging function,
the battery can be ‘refueled’ within 35 minutes at suitable charging
stations. At home, the battery of the E-Bugster can also be charged
from the 120-Volt outlets that are usual in America (or from 230-Volt
outlets in Europe). The interface for the charge cable is located below
the normal ‘fuel door’ position near the C-pillar.
Thanks to a new Combined Charging Systems – which was developed in
cooperation with German carmakers Audi, BMW, Daimler, Porsche and
Volkswagen as well as American partners Ford and General Motors /
Opel – the the E-Bugster can be ‘filled up’ via an interface using any of
the available charging modalities. Possible are:
• Single-phase charging with AC current and
• Ultra-fast DC charging at electric charging stations.
This will require the development of a new, uniform industry standard
for the plug connectors of future electric vehicles that will be available to
all manufacturers. And this standardisation even goes beyond the plug
connector itself: in the Combined Charging System, the charge controller
and the electrical architecture must be able to handle all charging types.
This will reduce costs and simplify widespread global implementation
of electric mobility.
Charging the battery while braking
Just how much energy the driver of the E-Bugster is requesting with the
‘electric pedal’ at any moment is shown in a power display. Instruments
also include a driving range indicator and a display showing the
battery’s charge state. Also new in the Beetle is an instrument that
shows the driver the intensity of battery regeneration. Regeneration
refers to the recovery of braking energy: as soon as the driver’s foot
leaves the accelerator pedal and /or brakes, kinetic energy is converted
into electricity which is stored in the battery. This increases the driving
range of the E-Bugster. By the way, Volkswagen calls the complete
electric drive unit Blue-e-Motion. As early as in 2013, units under this
name will go into production in such vehicles as the Golf.
Visions become versions
Bugster? That sounds familiar. Of course: Ragster! That was in January
2005. Also in Detroit. Where Volkswagen presented a New Beetle as
a speedster with a swept-back ragtop (folding roof) – the Ragster.
A design vision for the Beetle of tomorrow. Wider, lower, sportier.
In 2005, the slogan for the concept’s feasibility was expressed as:
“Everything is conceivable!”. In 2012, it had advanced to: “Everything
is feasible!” Because the idea of the Ragster – wider, lower, sportier –
became a reality (with the exception of the ragtop) in October 2011 in the
current production Beetle. So, what does the name E-Bugster actually
signify? That is easy to explain: a combination of the supplemental
identifier ‘E’ for electric models, the American nickname for the Beetle,
‘Bug’ and the vehicle type ‘speedster’ that describes an open-top
two-seater.
Proportions of a sports car
The E-Bugster is a Beetle that could hardly be made to look more
dynamic. Actually, it is a sports car. It has a height of less than
1,400 mm, which is about 90 mm less than that of the hard top Beetle.
And the production model already looks really powerful with its sharply
sculpted proportions. The E-Bugster’s width (1,838 mm) grew by 30 mm,
while its length (4,278 mm) is identical to that of the production car.
The E-Bugster displays very unique dynamic styling from every viewing
angle. Design details of production version were supplemented by new
styling elements. In its stance on the road, the concept car looks as
though it were cast as a single piece. This is due to a very simple fact:
in developing the production model introduced in October 2011, the
Beetle design team had already considered all potential derivatives for
future models on its radar screen of possibilities. And that is in part
how a speedster with an E-motor evolved, the E-Bugster.
Bugster front and rear
In front, it is the swept-back and wide windscreen that catches the eye;
its glass extends laterally to a point above the A-pillars. The E-Bugster,
which is equipped with LED headlights, is also distinguished by the
highly customized bumpers of the production Beetle: designers
integrated the daytime running lights to the left and right of the central
air intake as bands of LED lights in a C-shape (naturally mirrored on
the right side). Ever since the e-up! (concept car) was presented in
Europe, this form of daytime running light has been a type of signet
among Volkswagen electric vehicle studies. These styling elements also
appear in modified form as reflectors in the rear bumper, which was
also redesigned. The rear windscreen of the E-Bugster proves that the
rear windows of a speedster do not need to restrict visibility like the
arrow slits in castle walls: it is extremely wide.
Speedster side profile
A speedster needs swept-back windows and a low roof. The E-Bugster
has swept-back windows and a low roof! First, let us survey the car’s
side profile. Beneath the typically flared wheel housings there are
larger 20-inch versions derived from 18-inch Beetle ‘Twister’ wheels,
which are equipped with size 235 / 35 R 20 tires. Between the wings,
there is the ‘V’ on the flank that is typical of the most famous Beetle
ever. From the side sill, the viewer’s gaze moves upwards over the large,
smooth homogeneous surface of the door and the contour line above
the door handle that looks as though it were carved by a knife. Just
a few centimetres above this point, the Beetle becomes a speedster:
the designers lengthened the chrome strip of the lower window border
towards the rear; it now runs (as it did once on the New Beetle Cabriolet)
from A-pillar to A-pillar. The hard top of the ‘Bug’ extends in a low
arc above this line of chrome. Following the roof radius – in classic
speedster style – is the upper border of the side windows. The height
between the chrome lower window border and the uppermost roof line
is a low 400 mm. And that is how it should be for a speedster!
Progressive interior
The combination of high-tech equipment and dynamic performance
is also reflected in the interior. Sport seats and a continuous centre
tunnel in body color underscore the sporty character of the E-Bugster.
The use of aluminium as the material for the door handles and belt
guides, and the lightweight construction styling of the steering wheel
also produce a direct connection between the exterior and interior.
Starting the E-Bugster is a unique experience: the Start button not only
activates the drive system; it also puts a light show into motion: first,
the interior is immersed in a white light, then a blue light. It begins with
a light pulse in the instrument cluster; from there the light emanates
as a thin line of light, just one millimetre wide, coursing into the door
window sills and around the air nozzles – a kind of visual awakening of
the E-Bugster.
World premiere of the Jetta Hybrid at the North American International Auto Show
- World premiere of the new Jetta Hybrid in Detroit
- First hybrid model with 1.4 TSI four-cylinder and 7-speed DSG
- New Jetta Hybrid from Volkswagen drives in pure electric mode at the push of a button
Wolfsburg / Detroit, January 2012. Volkswagen is presenting one
of the world’s most efficient automobiles at the North American
International Auto Show in Detroit: the Jetta Hybrid. Providing
propulsion are a high-tech petrol engine (TSI with 110 kW / 150 PS)
and a zero-emissions electric motor (20 kW). While this hybrid alliance
enables
very impressive driving performance (0-60 mph in less than
9 seconds), the new Jetta Hybrid also produces an equally impressive
fuel consumption value (combined mode) of 45 mpg1). This means that
the sporty saloon consumes about 20 per cent1) less fuel than a comparably
powered car with a conventional drive system. In city traffic,
the fuel economy advantage climbs to 30 per cent1)! In addition, the new
Jetta Hybrid can be driven in pure electric mode, and therefore with zero
emissions, at speeds of up to 70 km/h (44 mph) and over a distance of
2.0 km1) or 1.3 miles1) (depending on terrain and operating conditions).
Jetta Hybrid launches in November 2012, in North America first
Extremely quiet. After the Touareg Hybrid, the Jetta Hybrid is now the
second model from Europe’s most successful carmaker to have a drive
module under the bonnet which consists of a petrol engine and an electric
motor, paired to attain the lowest possible fuel consumption values
and excellent performance in all areas. Consider its comfort: overall,
the refined TSI, a newly designed exhaust system, use of an acoustic
windshield, thicker side windows in front and various other measures
have resulted in the quietest car that Volkswagen has ever offered in this
class. The saloon, which is as sporty as it is eco-friendly, will launch onto
the market in November 2012, initially in the USA and Canada.
TSI is one of the world’s most advanced petrol engines
Pure efficiency. For the first time in America, Volkswagen is using a
1.4-litre turbo petrol engine in the Jetta Hybrid. The TSI engines from
Volkswagen have won various awards, including one of the world’s
most prestigious in this field: the “Engine of the Year Award” for 2011.
Practice proven on the German Autobahn. The downsized four-cylinder
with a displacement of exactly 1,395 cc – millions of units of this engine
have already sold in Europe – develops a torque of 250 Nm at just over
the idling speed (from 1,400 rpm) and is extremely durable even at German
Autobahn speeds. The maximum power of this TSI even surpasses
that of the 2.5-litre five-cylinder engine in the conventionally powered
Jetta. The highlight is that the TSI can maintain this constant high maximum
torque up to 3,500 rpm. Together with the electric motor, the
drive system exhibits performance characteristics that make the new
Jetta Hybrid a sporty cruiser. Incidentally, the TSI is a lightweight unit
weighing 98 kg2).
TSI, decoupling clutch and E-motor form the hybrid module
High-tech alliance. The TSI forms the hybrid module together with the
electric motor and a decoupling clutch. This is integrated between the
two drives and fully disengages the petrol engine from the drivetrain
when in pure electric driving or ‘sailing’ mode (coasting / braking).
State-of-the-art battery technology. A lithium-ion battery supplies the
energy for driving the electric motor. The compact battery system is
integrated behind the rear bench seat. The results: no compromises
whatsoever in interior space. In terms of its construction, the battery
consists of 60 individual cells, each with an energy capacity of 5 Ah;
altogether, they produce a nominal voltage of 220 Volt and an energy
capacity of 1.1 kWh. Weight: 35.8 kg2). The frequent alternation
of discharging and charging cycles in hybrid operation requires
high-performance battery cooling, which in this case is handled by a
fan mounted directly on the energy storage device. The battery also has its own management system that performs safety, diagnostic and
monitoring functions as well as temperature management. Need-based
control of the fan (as a function of such factors as outside temperature
and momentary power demand) enables continual operation of the
battery within an optimal temperature window. Special protection
systems also electrically disconnect the battery when not in use or in
case of a crash.
Fast dual-clutch gearbox. Power transfer to the driven front axle is
via a 7-speed dual clutch gearbox (DSG) that operates automatically
and efficiently. The combination of a hybrid drive and DSG is unique
here, because it merges driving fun with sustainability. The proven
7-speed dual-clutch gearbox that is very popular in Europe, in this
new extension phase, sets the benchmark in this torque class of up
to 250 newton meters with its low weight of 74 kg and very compact
construction. Thanks to its lightweight drive components, the weight
of the Jetta Hybrid was only increased by 100 kg2) despite the a battery
system. Together with additional safety modifications to the vehicle
structure, the gross weight of the new Jetta Hybrid is still less than
1,500 kg2).
The right drive system mode for every situation
Zero emissions driving by electric motor. When the battery of the
Jetta Hybrid is sufficiently charged, the Volkswagen can, as
mentioned, be driven over a distance of up to 2.0 km (1.3 miles) in pure
electric mode and therefore with zero emissions. The Jetta Hybrid
is switched to electric drive mode either automatically (up to 60 km/h /
37 mph) or at the press of a button (up to 70 km/h / 44 mph). The driver
presses the E-mode button to the right of the gear shift lever to do this.
In both cases, the TSI is disengaged from the drivetrain by a decoupling
clutch, which reduces energy consumption and increases electric
driving range. About one-third of the fuel-saving potential in the Jetta
Hybrid is realised through electric driving.
Battery charging by regeneration. During braking, the Jetta Hybrid
switches over to a battery regeneration mode, which ‘captures’ kinetic
energy and feeds it into the battery as electrical energy. This is how
it works: As soon as the driver releases the gas pedal to brake, the
decoupling clutch opens to disengage the engine and reduce drag
torque losses in this phase. If the driver now activates the brake pedal,
the generating power of the electric motor increases – as a function of
pedal travel – and the electrical energy produced in this way is stored
in the battery. The stored energy is then available, either for electric
driving or boosting. The effect of battery regeneration should not be
underestimated; it represents another third of the fuel-saving potential
realised in the Jetta Hybrid!
In city driving the TSI is silent whenever possible. The Volkswagen’s
gasoline engine is stopped as soon as the car stops in city or stopand-
go traffic, provided that the driver presses the brake pedal and the
battery is sufficiently charged. However, the heating, air conditioning
system and electric convenience systems such as the audio system
continue to operate. Of special interest here is the fact that unlike in
conventional systems, not only is the Jetta’s petrol engine stopped; the
decoupling clutch also disengages the engine from the drivetrain to
enable a pure electric driving mode when the car drives off again as
an alternative to petrol engine driving – provided that the battery is
sufficiently charged. Another third of the fuel-saving potential in the
Jetta Hybrid is realised by frequent deactivation of the TSI.
‘Sailing’ without TSI. As soon as the driver releases the accelerator
pedal at higher vehicle speeds (up to 135 km/h / 84 mph), the TSI is shut
off and is also disengaged from the drivetrain via a decoupling clutch
to eliminate drag torque losses in this driving situation. As a result, the
Jetta Hybrid coasts further than is usual, without consuming any fuel.
Double the power with boosting. If the DSG gear selector is in the
‘S’ gear position or the manual shift gate, the drive system reacts to
vigorous accelerator pedal travel with maximum propulsive power.
The same applies to the classic kickdown (a quick press of the
accelerator all the way to the floor). In this case, the power of the
E-motor and the TSI combine to output a temporary peak power of 125
kW / 170 PS, which is applied to the front wheels via DSG. In automotive
jargon, this interplay of engine and motor is known as ‘boosting’.
Passing manoeuvres can be completed in the shortest of times thanks
to the extra power; and that offers a boost to active safety.
Driving with the petrol engine. On faster drives and/or when battery
capacity is low, the Jetta Hybrid is powered by just the TSI engine. In
these phases, the operating point of the TSI is also shifted to optimise
efficiency; it delivers more power than is needed for pure propulsion
of the Volkswagen. This excess power is utilised in a very specific way:
depending on the battery’s momentary charge state, the extra power
might be used to charge the high-voltage battery via the electric
motor – which in this case acts as a generator. These so-called active
charging phases are interspersed with electric driving phases to realise
the best possible fuel economy.
Comprehensive information for greater sustainability
New instruments. All relevant operating states are displayed by the
instruments of the Jetta Hybrid. The driver calls up information via
menus for the new instruments. Under the ‘Hybrid’ menu, the currently
active drive mode is displayed in an energy flow diagram, and the
direction of energy flow is visualised in the form of arrows. The battery
charge state is shown on the same screen. Directly below the energy
flow diagram is what is known as the ePower meter. This indicates the
relative power of the electric motor. The ePower meter is only active in
the ‘electric driving’, ‘E-mode’ and ‘Boost’ operating modes.
Power meter shows power source of hybrid drive. Of central importance
is the so-called Power meter (not to be confused with the ePower
meter). The Power meter – a multifunctional display that replaces the
tachometer and which is integrated on the left side of the instrument
cluster – informs the driver of the momentary operating state of the
Jetta Hybrid: a general readiness to drive (‘Ready’), battery regeneration
(‘Charge’), eco-friendly driving mode (‘Eco’), boosting (‘Boost’) or pure
internal combustion engine driving with the TSI (‘Off’). In addition,
electric driving – either automatic or manually selected by the driver –
is also indicated in the instruments (‘E-mode’).
Playfully visualising how efficiently one is driving. The audio system’s
display plays a role in this information strategy. The goal here is
an especially economical mode of driving. To this end, the ‘Zero
emissions’ menu offers a graphic display of the car’s driving time with
zero emissions. The zero emissions values are shown in the form of
per centages in a bar diagram, where the measurement interval of one
bar represents one minute of driving. A value of 100 per cent means
that the Jetta Hybrid was driven with zero emissions throughout the
driving minute, i.e. with the TSI engine shut off. A total time period of
30 minutes is considered.
Extensive safety and convenience features
Electronically stabilised. Standard equipment in the new Jetta Hybrid
includes an electronic stabilisation programme (ESP), anti-lock braking
system (ABS) and six airbags (driver and front passenger airbags, side
airbags in front as well as window airbags, front and rear). This pack
can be extended to include rear side airbags as an option.
SE – specified exterior. Visually, even the base version (SE) of the
Jetta Hybrid is distinguished by aerodynamic modifications that
include a new front spoiler, a rear diffuser and a rear spoiler that is
harmoniously integrated into the design. The results: the car’s Cd
value was improved by 10 per cent. In addition, the Jetta Hybrid SE
is equipped with LED rear lights in a new design as well as special
15-inch alloy wheels with all-season tyres optimised for low rolling
resistance. Hybrid signatures on the front, rear and side body
panels identify the new drive version. Other distinguishing features:
a special radiator grille where the VW logo is integrated on a blue
background for the first time. Exclusively reserved for the Jetta
Hybrid is the new body paint ‘Oryx white’.
SE – upgraded interior. Inside, the car features high-end seat covers
in ‘Titan black’ or ‘EcoTech’ design and new decorative strips with
the ‘Hybrid’ chrome signature, which identify the car as the Jetta
Hybrid SE. A 2-zone automatic climate control system (Climatronic)
with a new high-voltage air conditioning compressor ensures that
the interior can be cooled even without the petrol engine running.
Compared to the Climatronic used to date, this system also has the
new ‘maxAC’ function, which cools down the interior very quickly
at the press of a button. The technology of the Jetta Hybrid SE
was perfected by specific instruments that include an energy flow
diagram in the Premium 8 audio system, a trip computer, handsfree
telephone system (Bluetooth) and interface for iPod and other
multimedia sources as well as a multifunction leather-wrapped
steering wheel.
SEL1 and SEL2 are sophisticated. In the mid-level equipment version,
the SEL1, standard features of the new Volkswagen are extended
with such details as 16-inch alloy wheels, a tilt/slide glass sunroof,
RNS 315 navigation system, electric driver’s seat adjustment, seat
heating in front, and the Keyless Access system for door locking
and engine starting via a Start button. Customers who order the top
version, the SEL2, can also enjoy details such as 17-inch alloy wheels,
newly developed bi-xenon headlights with dynamic cornering lights
and automatic motorway lights, fog lights, reversing camera and a
new Fender sound system with 400 Watts of output power. And that
is how it should be. After all, who says that maximum sustainability
cannot be fun as well?
