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?
