Who has the better ko balance – vehicles with electric motors or those with burners? This question is discussed at Stammtisch, but also among scientists. How massive is the time-consuming battery production down to the very life of the car? And how much does fossil fuel affect total CO2 emissions?

These questions are answered strictly scientifically. This is done on the basis of "Life Cycle Assessments", a complex and elaborate, internationally standardized procedure with the help of which the LCA of vehicles is determined. Among other things, the carbon dioxide emissions are examined during all stages of car life from production to recycling.

VW has carried out such a certified LCA for its bestseller Golf. Rather, for two models: the e-Golf and a TDI. Clear result, according to the Wolfsburg: "The carbon footprint of the battery-powered E variants is already better than those of the corresponding vehicles with internal combustion engine." And: In the case of the Stromers, unlike the diesel, there is still a high potential for CO2 savings during operation – for example, through electricity produced using renewable sources.

The bottom line is that, according to the LCA, the TDI spans its entire life cycle with emissions averaging 140 grams of CO2 per kilometer, while the e-Golf comes to 119 grams. The distribution between production and operation is interesting. CO2 emissions from the construction of an e-Golf are 57 grams of CO2 per kilometer – because of the batteries. For the diesel, a share of 29 grams was determined.

In operation, the relationship then reverses. Provision and combustion of the light heating system in the TDI, calculated at 200,000 kilometers, account for 111 grams of CO2 per kilometer, while a vehicle with electric drive emits 62 grams per kilometer per kilometer.

The VW Group, which currently relies entirely on the electricity card, sees a number of opportunities for the future to significantly increase the lead of the Stromer in terms of lifetime emissions. Thus, the CO2 emissions for the batteries of the first I.Q. model, which is expected by the end of 2019, should be reduced by more than 25 percent per kilowatt-hour of battery capacity compared to the current e-Golf battery. If the power for driving is obtained exclusively from renewable sources, the CO2 emissions would drop to two grams during the utilization phase of 62 grams of CO2 per kilometer in the current EU electricity mix, according to the Lower Saxony.

The Zoe is still on the upswing: Renault's fully electric model of success more than doubled its registration figures in the first quarter of 2019 compared with the first three months of the previous year. Since the market launch in Germany in 2012, more than 20,000 Zoe have been sold. And that is just the beginning. Because the offer is significantly expanded.

Overall, Renault Germany can present a very successful interim balance for its Stromer. Front runner Zoe sold more than 1,100 times in March 2019 alone. By comparison, in the first quarter of 2018, there were around 1,300 units. The market share of the compact Fnftrers with electric drive is currently 17.1 percent. "From January to March, sales of the Zoe, Kangoo Z.E. and Master Z.E. models increased by 101.1 percent to 2,930 units," says the German importer.

And the power offensive of the French brand continues, with increasing stroke rate: At the Shanghai Motor Show was just the City K-ZE (read: Kej-si) abstolen. The small Stromer enters the A-segment and is expected to play a key role in the booming Chinese market. The sixth electric model of the Renault Group shows the current design DNA of Renault, as a fully everyday suitable city SUV has a ground clearance of 15 centimeters and a wheelbase of 2.4 meters. The latter results in generous space in the interior and a 300-liter boot.

"In fast charging mode, the battery can be charged to 80 percent of its capacity in just 50 minutes," promises Renault. The K-ZE is equipped with an on-board multimedia system with 8-inch touch screen, 4G Internet, intelligent voice recognition, navigation and real-time control of the electric vehicle functions. Particu- larly particulate matter sensors and an air quality control system, which automatically switches to recirculation mode when needed, are particularly helpful in China's megacities. Also on board: a reversing camera and the tire pressure monitor.

The next E-model, the test rig EZ-Flex, should complete its first test of fortune in hard practical use. With a length of 3.86 meters, a width of 1.65 meters and a height of 1.88 meters, the mini transporter is tailor-made for use in the city, its load volume of three cubic meters and its turning circle of only 4.5 meters prädiniert him for delivery and courier services on the last mile.

Its range is 100 kilometers – twice as much as in urban delivery traffic on average per day. Twelve copies will be loaned to companies across Europe, and they will use the EZ-Flex for two years.

As part of the strategy plan "Drive the Future" Renault wants to expand its offer by 2022 to eight electric vehicles worldwide. In addition there are twelve partially electrified models. For example, from 2020 the new Clio as Hybrid, Captur and Mgane will start as plug-in hybrid variants.

For light commercial vehicles, Renault is in good shape worldwide and especially across Europe. Now the successful product range is vigorously renewed and revised. In September 2019 and in the course of 2020, the results of this refresher will be rolled out to traders.

For the longest time, interested parties have to wait for the new Kangoo, which will be introduced in 2020. But as a pre-appetizer Renault now showed in his research center near Paris, the all-electric Kangoo Z.E. Concept. Its forms reveal that future Kangoo, Kangoo Rapid and Kangoo Z.E. approximate the design vocabulary of Renault cars. And at least the show car shows cameras as exterior mirrors – apparently the trend is unstoppable.

That with the design DNA is a good decision, because the current design of the brand is not only attractive, but also successful. As a highlight at Kangoo Z.E. Concept calls Renault the completely new light signature: A strip between the headlights in C-shape, which surrounds the rhombus. "A light band also extends from the brand logo on the rear to the vehicle flanks and thus emphasizes the rails for the side sliding doors," says the manufacturer.

This design gimmick is also used in the master's latest evolutionary stage. In the interior of the new instrument panel with plenty of storage compartments and new instrument cluster eye. It contains, among other things, a 5-inch display for the on-board computer. Also new: the navigation monitor is completely integrated into the cockpit.

The new masters are powered by the powerfully revised 2.3 dCi diesel with twin turbo, which is offered in several power levels up to 180 hp and 400 Newton meters of maximum torque. According to the less practical NEDC standard, they are to burn up to one liter less per 100 kilometers than the current engines. And thanks to their SCR catalytic converter, they consistently meet the Euro 6d-Temp emissions standard for passenger cars or Euro VI for trucks.

The master has also gained in driver assistance systems. It will be available from fall 2019 with dead-angle warning, crosswind stabilization and reverse assist. The purely electric master Z.E. remains unchanged drive technology, but takes over the other improvements of the diesel brother.

The Renault Trafic enters the class up to 3.0 tonnes gross vehicle weight and also undergoes a visual enhancement in the style of other light commercial vehicles. Its engine grows from 1.6 to 2.0 liters, the power range is between 120 and 170 hp.

According to Renault, the average engine with 145 hp compared to the comparable predecessor to consume up to 0.6 liters less. Here, too, the SCR catalytic converter ensures compliance with the Euro 6d Temp emissions standard. Except as a transporter Trafic will again be a nimble passenger transporter, in the finest version as a SpaceClass shuttle. The two highest performance levels will also be available in the future with dual-clutch transmissions – the clientele had already asked massively for it.

Fresh ingredients are also provided by the pick-up Alaskan. His facelift includes, among other things, a reinforced rear suspension with the resulting payload increase to 1.1 tonnes. Disc instead of drum brakes at the back count as well as emergency brake assist, trailer stability control and smartphone integration via Android car and Apple CarPlay.

At the i-Mobility 2019, the Smart Mobility Fair, the car industry will mainly show new electric cars and hybrid models. For example, Peugeot presents two vehicles that are all about sustainable technologies: the all-electric compact car e-208 and the compact SUV 3008 with hybrid drive. Both cars will be available from winter 2019 on the market. I-Mobility will take place from April 25 to 28, 2019 in Stuttgart.

"With the new Peugeot 208, we are implementing our new strategy of flexibility," says Steffen Raschig, Managing Director of Peugeot Germany. "Our customers choose a model and the right drive for their lifestyle." The SUV segment is also continuing the quest for sustainable mobility: The Peugeot 3008 comes with four-wheel drive and is equipped with state-of-the-art hybrid technology, according to Raschig.

The e-208 is powered by an electric motor with 100 kW / 136 hp and thus reaches a distance of 340 kilometers according to WLTP standard. The engine develops from the stand a maximum torque of 260 Newton meters. Meanwhile comes the 3008 Hybrid4 with the "PureTech engine" and two electric motors, which are installed respectively on front and rear axle, on a total output of 220 kW / 300 hp. The compact SUV accelerates from 0 to 100 km / h in 6.5 seconds and leads to WLTP standard up to 50 kilometers purely electric.

Electromobility has long been a big name in the giant Chinese empire. The People's Republic, with more than 1.4 billion people, is the fastest growing market for electric vehicles. Any manufacturer who's up for it would of course like to get involved with its Stromers in China.

Now the Renault Group is also entering and presenting the new City K-ZE at the Shanghai Motorshow on April 16, 2019. The all-electric city SUV is the first production vehicle of the joint venture of the Renault Group and the Dongfeng Renault Automotive Company (DRAC).

The City K-ZE is the sixth electric model of the French manufacturer and part of the strategic plan "Drive the Future?" By 2022 Renault wants to expand its electric range to eight pure electric and twelve electrified models.

Electromobility is becoming increasingly important to car manufacturers. Sports car manufacturers like Porsche are already thinking of production in the coming decade, when the all-electric Macan will roll off the production line. And so Porsche Leipzig GmbH is integrating the axle assembly for the Macan on site – a logical step.

To date, the plant has outsourced this step to a system supplier who will continue to work for the current Panamera and Macan models. In future, Porsche Leipzig will be producing its axles for electric vehicles on its own, which will make production at the site even more flexible and efficient. At the same time, more than 100 highly qualified jobs will be created, says Porsche.

"The drive is a unique feature of our sports cars," says Albrecht Reimold, Board Member for Production and Logistics at Porsche AG. "And since electric vehicles need to see the aggregates in combination with the axles, we will take over the axle production ourselves." This integration is a central component of the brand and factory strategy: "We are thus increasing our manufacturing expertise and investing in the future viability of the Leipzig plant."

The axle assembly will be located in the immediate vicinity of the plant, they say. The implementation of Porsche Production 4.0 will make the processes much smarter and leaner. Together with the technical development, for example, all processes are digitally and virtually secured at an early stage.

With the expansion of the Leipzig plant, Porsche also wants to create the necessary conditions to be able to produce all-electric vehicles on the existing production line in addition to gasoline and hybrid models. According to Porsche, the Saxon site is to be converted step by step into a plant for electromobility.

Peugeot repositions itself in terms of electric mobility. Two vehicles are now celebrating their premiere: the all-electric Peugeot e-208 and the Concept 508 Peugeot Sport Engineered Neo-Performance with hybrid drive.

The e-208 is based on the design of the coupe sedan 508. He has an electric motor with 100 kilowatts (136 hp). Three driving modes are part of the electric vehicle, with the Sport mode accelerating the e-208 from 0 to 100 km / h in 8.1 seconds.

The study based on the new Peugeot 508 is equipped with three engines: a PureTech 200 petrol engine, an 81 kW / 110 hp electric motor at the front and an electric motor with 147 kW / 200 hp at the rear. The car can travel up to 50 kilometers purely on electricity. According to Peugeot, it emits only 49 grams CO2 / km according to the WLTP standard in an average driving day.

With the computing power of about 15 laptops in the trunk are currently five e-Golf in Hamburg on the move. With them VW tests the automated vehicles in public city traffic. On board, the test vehicles also have laser scanners, cameras, ultrasonic sensors and radar equipment.

The test vehicles are used on a three-kilometer stretch of the test track for automated and networked driving (TAVF) in the Hanseatic city. "The tests focus on both the technical possibilities and the requirements placed on the urban infrastructure," says Axel Heinrich, Head of Volkswagen Group Research.

The enormous computing power of up to five gigabytes per minute per vehicle and the precise sensor technology should ensure that "pedestrians, cyclists, other cars, intersections, right of way, parked vehicles and lane changes are detected in flowing traffic at shortest distances and in milliseconds", is it[calledForsafetyreasonsaspeciallytrainedtestdriveronthesteeringwheelwhoconstantlychecksalldrivingfunctionsandcaninterveneincaseofemergencysitspermanentlyatthetestdrivingonlevelfourforautonomousdriving

The next winter is coming. That's why Mercedes-Benz is already testing the polar circle with the electric eSprinter. Because Klte is one of the biggest challenges for electric vehicles. In the final test, Daimler demonstrates: Even in arctic conditions, the electric commercial vehicle is still reliable on the last mile.

For several weeks, the development team subjected the fully electric transporter in Arjeplog, Sweden, to an ice-cold hearing test. At temperatures of up to minus 30 degrees Celsius, icy roads and deep snow, the eSprinter should prove its ability to operate under extreme conditions. Now the vehicle has reached one of its last milestones on the way to market launch in the second half of 2019.

For electric vans to function reliably in hard everyday use, for example in the CEP industry (courier, express, parcel), it is crucial how the vehicles react to different weather conditions.

With a range of around 150 kilometers in the configuration with an installed battery capacity of 55 kWh, the eSprinter is optimally designed for domestic delivery traffic. The tests in Sweden have shown that the customer still has a range of around 100 kilometers even with the unfavorable wet conditions here.

Even at temperatures far beyond the freezing point, the windows must defrost as quickly as possible and the driver's cab can be reliably heated. For this purpose, the test vehicles, including batteries in special cold cells were initially brought to minimum temperature, to then test the starting behavior and thermal management during cold start.

Another important element of the hardness test: the charging behavior. The eSprinter has an integrated fast-charging function, which allows it to recharge around 80 percent of its energy within 30 minutes – a huge plus in the flexibility of day-to-day transports, which must function reliably regardless of the temperature.

"Thanks to our extensive tests, we were able to get the last percent of our second all-electric transporter after the eVito on the way to full market readiness," says Benjamin Kaehler, Head of eDrive @ Vans at Daimler. Particularly in the discipline of thermal management, which is so essential for electric vans, important insights have been gained to make the eSprinter even safer and more comfortable.

In Arjeplog, the eSprinter went through its last winter tests before following the eVito in the second half of 2019. The new eSprinter is initially offered as a panel van with a high roof and a permissible gross weight of 3,500 kilograms.

A long-awaited victory can release power in motorsport and give a lot of backwind. Without question he motivates, drives, makes proud. Above all, he is the reward and the confirmation of hard work. As in the technology partnership between ZF and Venturi in Formula E: The first win by Edoardo Mortara and the fifth place by Felipe Massa last at the fifth race of the season in Hong Kong meant the most successful race weekend so far. For ZF, the involvement in the electric series is fundamentally a success, as the technology group receives impulses that are directly incorporated into series development through the know-how acquired and tested in racing. And bring with it competitive advantages.

The partnership between ZF and the Venturi racing team, which has existed since 2016, was a particular challenge in 2018, as the electric series entered a new era with new cars. Fr ZF meant that the company developed an electric drive for the Venturi team, which was responsible for an electric Engine, a newly developed gearbox and the power electronics includes. The electric drive for the cars of the Monaco-based team has a maximum output of 250 kW.

Important in the development: an increase in efficiency, a maximum weight saving and a high durability. In order to combine maximum efficiency and weight savings, ZF used its system competence.

The electric drive achieves an extremely low system weight and efficiency, which is significantly higher than that of series applications, thanks to well-designed transmission and power electronics. A lower weight is achieved, for example, by the use of a metallic lightweight alloy and carbon. New ways of cooling and lubrication provided, in the end, a greater efficiency and a longer range of the battery, which has to hold a whole race distance since this season.

One big plus: "The experience we have gained with the racing application will have many effects on future ZF products," says Jrg Grotendorst, Head of the ZF E-Mobility Division. One example is the silicon carbide in power electronics, whose serial production ZF plans in about three to four years.

All the experience and data that ZF collects every mile in Formula E is directly incorporated into the further development of this new technology. And that's a lot: Over the course of a season, there are more than 5,000 race and qualifying kilometers in 13 races. Even concepts that ZF initially developed specifically for motorsport should gradually be used in series applications, such as a special winding process for the stator of the electric motor.

The development of the electric drive for racing has also had a positive effect on the test facilities. The requirement for the measuring accuracy of the test environment was high, which is why this precise set-up now also brings advantages in the testing of ZF pre-production projects.

And the need to overcome limits and go new ways under time pressure will also be reflected in future development projects. Because the system development in the formula E is similar to that of electric minibuses and vans, for which ZF also develops electric drives. The performance of ZF engineers, even without a sophisticated specification, to a viable concept and an optimal system approach, will prove to be a competitive advantage.
