Volkswagen has released
some a lot of new details on their electrified conversion of the popular selling Golf passenger car, along with a status update.

The e-Golf which is now on sale in Germany and other selected regions of Europe goes on sale in the US shortly.
There was still no mention by VW of offering the car on a national level; so we imagine sales will be limited in the near term to the "compliance" states in the US.
"The 2015 e-Golf is Volkswagen’s first fully electric vehicle for the U.S., due to go on sale in select states (and only at participating dealers) in the fourth quarter of 2014. The all-new model is part of a structured powertrain strategy that will lead to the introduction of new and highly efficient drive systems, and is part of Volkswagen’s holistic approach to sustainability called Think Blue®. Volkswagen has stated that it aims to be the world leader in e-mobility among automakers by 2018."
We are still more than a little skeptical of Volkswagen's aim to be the "world leader in e-mobility" in two and a half year's time; but heck, good to have goals...better for everyone if they follow through in the end!

We Caught This VW e-Golf Cutaway At The Geneva Motor Show This Year
The Volkswagen e-Golf is still yet to be rated in the US, but we feel looking at comparable specs and ratings on the car from elsewhere in the world, the official number will land around 78-80 miles on the EPA cycle. We should note that VW did make a fairly unhelpful statement this week on range of the e-Golfs headed to the US:
"Depending on driving style and charging behavior, the average real world range for the e-Golf is between 70 and 90 miles, while maximum range is approximately 115 miles. Helping ensure optimal performance in cold weather is a newly developed heat pump. The pump uses both ambient air and heat from the drive system components to heat the cabin rather than relying solely on the high-voltage heater, helping to reduce on-board electrical consumption significantly, especially in winter driving."
One Of The Ways You Know It's Not Your "Average" VW Golf
The VW e-Golf has three driving profiles: “Normal”, “Eco” and “Eco+”, with "Normal" being the default setting.
- Volkswagen says to "extend the range", the first option is the “Eco” mode. This dials back the electric motor's max power to 94 hp and the starting torque to 162 lb-ft. At the same time, the car modifies output of the air conditioning system and modify the response curve of the accelerator pedal. In this mode the e-Golf's top speed is reduced to 72 mph and 0 to 60 mph runs take about 13 seconds.
- In “Eco+” mode, as one would expect limits the car's abilities even more. Max output is now 74 hp and 129 lb-ft of torque. You also get a further flattening of the accelerator pedal;s response curve ... and the air conditioning is disabled. Top speed is now 56 mph and accelerates at a correspondingly slower rate.
No pricing for the US has been released as of yet. In its home market the e-Golf has a price-tag of 34,900 euros in Germany, which is just 50 euros cheaper than the BMW i3. We would not be surprised to see a MSRP around $37,499 for the US.
2015 VW e-Golf ... Complete With Over-The-Top EV Badging
VW's full press release can be found below:
Herndon — The 2015 e-Golf is Volkswagen’s first fully electric vehicle for the U.S., due to go on sale in select states in the fourth quarter of 2014. The all-new model is part of a structured powertrain strategy that will lead to the introduction of new and highly efficient drive systems, and is part of Volkswagen’s holistic approach to sustainability called Think Blue®. Volkswagen has stated that it aims to be the world leader in e-mobility among automakers by 2018.
We Also Found The VW e-Golf At The New York Auto Show This Year
Although Volkswagen has sold more than 30 million Golf models worldwide, this is the first model sold that produces zero tailpipe emissions and operates fully on electric power. The e-Golf is available in four-door form only and is immediately recognizable by its unique aluminum-alloy wheels and LED headlights, the first VW to be equipped with the technology in the U.S.-market. The LED headlights are more energy-efficient than Bi-Xenon systems, yet produce more light. Featuring a signature C-shaped design, the highly efficient LED daytime running lights are a distinguishing feature of all Volkswagen electric vehicles and come standard on the e-Golf. Another striking feature is the blue colored accent line that travels across the top of the radiator grille and is matched by blue accents throughout the interior. The blue accent appears on all efficient Volkswagen models (including all plug-ins) and consciously aligns the e-Golf and other models with Volkswagen’s global Think Blue initiative.

The e-Golf is powered by a 115-horsepower electric motor. From a standing start the EEM-85 synchronous permanent-magnet AC motor develops an impressive, class-leading 199 pound-feet of torque, allowing the e-Golf to reach 25 mph from rest in 4.2 seconds and to get to 60 mph in approximately 10 seconds. Top speed is electronically limited to 87 mph.
The high-performance 12,000-rpm motor and the single-speed EQ270 transmission form a compact unit; the EQ270 also incorporates an integrated differential and an electro-mechanical parking brake. The motor and transmission were developed in-house and are made at Volkswagen’s components plant in Kassel, Germany.
Depending on driving style and charging behavior, the average real world range for the e-Golf is between 70 and 90 miles, while maximum range is approximately 115 miles. Helping ensure optimal performance in cold weather is a newly developed heat pump. The pump uses both ambient air and heat from the drive system components to heat the cabin rather than relying solely on the high-voltage heater, helping to reduce on-board electrical consumption significantly, especially in winter driving.
Quick Shot Of The e-Golf's "Gearbox" From The LA Auto Show
The Golf A7 was developed from the outset to be one of the most efficient compact Battery Electric Vehicles (BEV) available. As the Modular Transverse Matrix (MQB) architecture that underpins the new Golf A7 is so flexible, Volkswagen was able to integrate the lithium-ion battery in a space-saving frame in the vehicle floor, under the front and rear seats and in the center tunnel. Like the electric motor and the transmission, the battery pack was also developed in-house at Volkswagen and is made at the company’s facility in Braunschweig, Germany. Volkswagen partnered with Panasonic to develop the battery chemistry for the lithium-ion cells used in the battery.
The lithium-ion battery accounts for 701 pounds of the e-Golf model’s 3,090-pound curb weight. It is composed of a total of 264 individual prismatic cells, which are integrated into 27 modules (each with six or twelve cells). Collectively, the cells have a nominal rating of 323 volts, with an overall capacity of 24.2 kWh. A battery management controller performs diagnosis and monitoring functions and also regulates the temperature balance in the battery junction controller (the interface to the motor’s energy supply). When the car is not in use or in the event of a collision, power from the battery is automatically cut off. To combat extreme temperature conditions, the battery management controller utilizes intelligent thermal control to ensure that temperatures inside the battery remain within the ideal range for optimal performance.
A central element of the drive system is the power electronics module. This controls the flow of high-voltage energy between the electric motor and the lithium-ion battery, depending on the battery voltage, which runs between 250 and 430 volts. During the process the power electronics module converts the direct current (DC) stored in the battery into alternating current (AC). The power electronics therefore have the following interfaces: the traction circuit connection to the battery; the three-phase connection to the electric motor; the plug connection from the DC/DC converter to the 12-volt power circuit; and a connection for the high-voltage power distributor.
VW e-Golf Standard On Board 7.2 kW L2 Charging & Standard CCS Quick Charging Port
Charging concept and equipment
There are several different ways of charging the e-Golf’s battery, via the car’s standard 7.2 kW onboard charger. The most optimal solution is the available 240-volt wallbox for a garage or carport: this charges at 7.2 kW, enabling a completely flat battery to be fully charged in less than four hours. If a 220/240-volt connection is not available, the most cost-effective and easiest alternative is to plug the standard charging cable into a 110/120-volt electrical socket, which will take around 20 hours to charge the battery.
The standard Combined Charging System (CCS) plug gives the e-Golf the capability to also take advantage of DC fast charging infrastructure. In this case the car can be recharged at CCS-equipped DC fast charge stations at levels of up to 40 kW, allowing the battery to be charged to 80 percent in around 30 minutes. For added flexibility, the charging process can be activated—immediately or programmed for later—by pressing a button next to the charging socket under the “fuel cap” or through an available iPhone® or Android® app.
Innovative driver control
The e-Golf features two technologies that allow the driver to control the vehicle’s energy use: three driving profiles designed to preserve energy (“Normal”, “Eco”, and “Eco+”); and three different levels of regenerative braking (“D1”, “D2”, and “D3”/”B”).
“Eco” and “Eco+” driving profiles. The e-Golf has three driving profiles: “Normal”, “Eco” and “Eco+”. The car automatically defaults to “Normal” mode upon start up. To extend the range, the first option is the “Eco” mode, which pares back the electric motor’s maximum power output to 94 hp and the starting torque to 162 lb-ft. In parallel, the electronics reduce the output of the air conditioning system and modify the response curve of the accelerator pedal. In Eco mode, the e-Golf is limited to a top speed of 72 mph and 0 to 60 mph acceleration is increased to approximately 13 seconds.
In “Eco+” mode, the electronics limit the power output to 74 hp and the starting torque to 129 lb-ft, further flatten the accelerator pedal response curve and the air conditioning is switched off. The e-Golf now reaches a top speed of 56 mph and accelerates at a correspondingly slower rate. Nevertheless, full power, maximum torque, and the 87 mph top speed can be obtained if the driver depresses the accelerator pedal fully down in either “Eco” or “Eco+” mode.
VW e-Golf Shows Its Inner Self At The Geneva Motor Show
Regenerative braking settings. In addition to the driving modes, the regenerative braking system can also be used to manage range. There are three driver-selectable levels available: “D1”, “D2”, and “D3”/”B”. To switch levels, the driver taps the “shift” lever to the left once, twice, or three times. Tapping the knob to the right moves sequentially back to “D”. If the lever is pushed to the right and briefly held there, the electronics switch straight back to “D”. The driver activates regenerative braking level “B”, which is the same as “D3”, by pulling the lever backwards.
In an electric car this amount of flexibility can lead to a different way of driving. It is possible to use regenerative braking consciously to slow the e-Golf down. Level “D1” regenerates energy and slows down the car the least, while level “B” has the strongest effect. At levels “D2”, “D3” and “B”, the deceleration via regenerative braking is so strong that the brake lights come on automatically. However, if the battery is fully charged, no energy regeneration takes place.
Volkswagen took very specific measures to lower the e-Golf model’s coefficient of drag (Cd) to 0.28. Among these were: reducing the volume of cooling air via a radiator shutter and partially enclosed radiator grille; new underbody paneling; a rear spoiler and C-pillar air vanes to better manage airflow at the tail of the car; and cleaning up the airflow around the wheels, largely by ensuring they are flush with the wheelarches.
Closer Look At The e-Golf's Wheels From The LA Auto Show
Electric drive systems present an acoustic challenge because the noise from an internal combustion engine is absent and thus different sources of sound become noticeable, while wind and tire noise become even more apparent. In addition, barely perceptible yet very specific electric drivetrain noises are joined by the sounds and vibrations of the electrically powered auxiliary components. To help ensure pedestrians can hear this almost silent vehicle coming, the e-Golf has a low-speed sound system installed.
Volkswagen specifically tailored the acoustics of the e-Golf for an electric vehicle, making it an almost silent cruiser. For instance, the powerplant’s subframe was changed to a pendulum mount: despite the electric motor’s high torque build-up when accelerating, this greatly enhances the acoustics. The motor housing unit was also specifically designed to achieve an extremely low level of noise emission. Finally, the interior uses highly sound-absorbent and yet very lightweight materials to produce a vehicle that is quieter than many luxury cars.
Visually the e-Golf is distinguished by its energy-efficient LED headlights, used here for the first time on an American Volkswagen model. Compared to Bi-Xenon lights, the LED system produces more light despite consuming less power. Going forward, Volkswagen electric cars will feature a C-shaped LED DRL signature in the redesigned front bumper. The lack of tailpipes at the rear of the car is an obvious clue that this is an EV, along with the badging and blue highlights on the VW logo. Other e-Golf design features include aerodynamically optimized 16-inch aluminum-alloy wheels with low rolling resistance 205-section tires.
Interior. At launch, the e-Golf will be available in SEL Premium trim. This well-equipped, top-line trim offers an extremely high level of available equipment, including: a touchscreen navigation system; VW Car-Net® connected services; Keyless entry with push-button start; heatable front seats; a leather-wrapped multi-function steering wheel; Bluetooth® technology; V-Tex leatherette seating surfaces; available SiriusXM® Satellite Radio; a rear-view camera; and Park Distance Control. The interior is also enhanced by blue elements, including the decorative seams on the steering wheel and shifter, plus the floor-mat edgings.
In addition, the e-Golf has a new instrument layout. The tachometer, which normally lives on the left-hand-side of the instrument cluster, is replaced by the power display—which indicates if the motor is ready, the battery is being charged via regenerative braking, or power is being drawn off—and an indicator of available output.
To its right, there is a conventional speedometer. The lower section of the speedometer now has an indicator showing the high-voltage battery’s state of charge. The color display between the power gauge and the speedometer now indicates the driving range, the current level of regenerative braking, and the remaining charging time and the type of charging connection. In a separate LED field at the lower segment of the multifunction display, the “READY” message also appears after starting the motor.
The touchscreen in the center console is also equipped with additional functionality, such as:
- Range monitor: this provides a graphic illustration of the vehicle’s current range. The impact that auxiliary components such as the air conditioning or heater would have on range is also displayed; the driver can gain additional range by switching these off.
- Energy flow indicator: this depicts the energy flow when accelerating (blue arrows) and when regenerative braking is happening (green arrows). Regenerative braking statistics show the amount of energy recovered since the start of the journey.
- e-manager: this enables drivers to pre-program up to three departure and charging times. At the defined time, this helps ensure that the vehicle has the air conditioning level set and the battery charged.
Driver Assistance Systems
The e-Golf features as standard a new assistance system called the Automatic Post-Collision Braking System (APCBS). Studies in accident research have shown that about a quarter of accidents that involve personal injury are of the multi-collision type—in other words, there’s a second impact after the initial collision.
The APCBS automatically slows the vehicle when it is involved in an accident in order to significantly reduce its residual kinetic energy. The system is triggered based on detection of a primary collision by the airbag sensors. Vehicle braking by means of the system is limited by the ESC control unit to a maximum rate of 0.6 g.
Yeah, We Know, Everyone Wants To See The Trunk On Conversions Of Petrol Cars...However, The People At VW Did A Nice Job Integrating The Batteries
Volkswagen intends to make the e-Golf ownership experience as seamless as possible. This includes offering a Roadside Assistance Plan that’s designed to take the anxiety out of “range anxiety”. For instance, if the customer runs out of charge and is within 100 miles of their home, Volkswagen’s Roadside Assistance provider will deliver the car to a nearby and convenient source for charging and will even pay for the customer to take a taxi home or to work if they decide not to travel with the car. The plan covers unlimited events.
The e-Golf will have its own dedicated “VW Car-Net e-Remote” app that will allow owners to adjust vehicle settings via a compatible smartphone or the VW Car-Net website. The app will contain the following functions:
- Climate control: Starting and stopping the auxiliary climate control function, plus a display of the outside temperature and the target temperature for the car’s interior.
- Charging the battery: Starting and stopping the charging process, indicating charger connection status, charge status, charge progress, charge level, charge start time and range.
- Accessing vehicle data: Information display relating to individual journeys (single trips or long term), such as miles driven, journey time, electric motor power consumption, power consumption of auxiliary components such as air conditioning and radio, use of regenerative braking.
- Vehicle status queries: Doors and trunk locked, lights (on/off), charging cable plugged in, position where the car was last parked (GPS position on a map).
