BMW Brilliance Automotive (BBA) opened a new engine plant with a light metal foundry in Shenyang today. The new location will produce the latest generation of the BMW TwinPower Turbo three and four-cylinder gasoline engines and forms part of the BBA production network based in Shenyang in Northeastern China.
In addition to combustion engines, the new engine plant will also produce high-voltage batteries for future Plug-in Hybrid models. As with engine assembly, this project will entail close cooperation between BBA and the BMW Group to ensure knowledge transfer from high-voltage battery production in Germany.
Audi Brussels to produce exclusively e-tron quattro SUV, battery packs; A1 production moving to Spain
January 20, 2016
As of 2018, Audi Brussels will produce exclusively the commercial version of Audi’s e-tron quattro battery-electric SUV (earlier post). The plant will also produce its own battery packs. The site in Belgium will thus become a key plant for electric mobility at the Volkswagen Group.
Audi will transfer production of the Audi A1 from Brussels to Martorell in Spain; in 2014, Audi Brussels produced 115,378 Audi A1 models. The Audi Q3, currently produced in Spain, will be built in Győr (Hungary) in the future. The model rotation will benefit all the sites of its global production network, Audi Chairman Rupert Stadler said.
HeidelbergCement and Joule partnering to explore carbon-neutral fuel application in cement manufacturing
December 14, 2015
Joule, a pioneer in the production of liquid fuels from recycled CO2, and HeidelbergCement, a German multinational building material company, are partnering to explore application of Joule’s technology to mitigate carbon emissions in cement manufacturing. Cement manufacturing is highly energy and emissions intensive, currently contributing about 6% of global CO2 (Zhang et al. 2014).
As part of the agreement, emissions (or offtake gas) from various HeidelbergCement factories could provide Joule with the waste CO2 required to feed its advanced Helioculture platform that effectively recycles CO2 back into fuel.
KIT researchers developing low-pressure carbonitriding process for hardening steel with methylamine; applications in downsized engines
November 23, 2015
A team at the Karlsruhe Institute of Technology (KIT) is developing a new low-pressure process for hardening steel using methylamine. The new low-pressure carbonitriding (enriching low-alloy steels with carbon and nitrogen) process saves time and process gas. Steels hardened in this way are suited for use in components subjected to high mechanical and thermal loads in downsized, energy-efficient and low-emission engines of the future.
The KIT researchers, along with their colleagues at Bosch, presented the process in a recent paper published in HTM - Journal of Heat Treatment and Materials.
KAIST researchers develop mechanical nanoscale fasteners for fuel cell membranes; lower cost, higher efficiency, easily manufactured
November 09, 2015
Scientists at KAIST have developed a physical interlocking interface that can tightly bind a sulfonated poly(arylene ether sulfone) (SPAES) membrane and a Nafion catalyst layer in PEM fuel cells, paving the way for lower-cost, higher-efficiency and more easily manufactured proton exchange membrane (PEM) fuel cells. They reported on their work in a recent paper in the journal Advanced Materials.
To generate electricity, PEM fuel cells rely on two chemical compartments separated by a permeable catalyst membrane. This membrane acts as an electrolyte; a negative electrode is bonded to one side of the membrane and a positive electrode is bonded to the other. The electrolyte membrane is often based on a polymer of perfluorosulfonic acid. Due to its high cost, however, a less expensive hydrocarbon-based electrolyte membrane has attracted interest in this technology sector.
Mazda’s new Aqua-tech Paint System receives Prime Minister’s Award; lower VOCs than Three Layer Wet
Mazda Motor Corporation’s new paint system—the Aqua-tech Paint System—has received the Prime Minister’s Award (Manufacturing and Production Process Category) at the 6th Monodzukuri Nippon Grand Award ceremony. The Aqua-tech Paint System reduces emissions of volatile organic compounds (VOCs) compared to Mazda’s previous oil-based paint systems without increasing energy consumption (and associated CO2 emissions).
Mazda had already achieved world-class low CO2 emission levels with the implementation of the Three Layer Wet Paint System. The company’s follow-on goal was to further reduce volatile organic compound (VOC) emissions to world-class levels.
Vaporized Foil Actuator Welding technique from OSU uses 80% less energy and delivers bonds 50% stronger; joining dissimilar materials
October 30, 2015
Engineers at The Ohio State University have developed a new welding technique—Vaporized Foil Actuator Welding (VFAW)—that consumes 80% less energy than a common welding technique, yet creates bonds that are 50% stronger. The new technique could have a significant impact on the auto industry, which is poised to offer new cars which combine traditional heavy steel parts with lighter, alternative metals to reduce vehicle weight.
Glenn Daehn, professor of materials science and engineering at Ohio State, who helped develop the new technique, explained the new process in a keynote address at the recent Materials Science & Technology 2015 meeting. The Materials Science & Engineering annual meeting is organized by the American Ceramic Society, the Association for Iron & Steel Technology, ASM International, and the Minerals, Metals & Materials Society.
Audi using Alstom H3 plug-in hybrid shunting locomotive at Ingolstadt
Audi has begun using a new 1,000 horsepower plug-in hybrid shunting locomotive manufactured by Alstom in daily operations at the Audi plant in Ingolstadt, Germany. The new locomotive runs without any emissions inside the plant buildings and can operate for up to two hours at a time in purely electric mode. Its battery is plugged in during breaks for recharging with CO2‑free electricity, or is supported while in motion by a diesel engine.
The three-axle Alstom H3 hybrid locomotive is significantly quieter than its conventional counterparts, and can deliver up to a 50% reduction in diesel fuel use, with a concomitant reduction in CO2emissions. This means that the plug‑in‑hybrid locomotive emits up to 60 tons less CO2 each year. For the Ingolstadt plant, this is another stage on the way to the CO2‑neutral factory.
Acura provides more technical detail on NSX sports hybrid AWD powertrain, body
October 28, 2015
Acura unveiled the production model of the next-generation NSX at the North American International Auto Show (NAIAS) this past January (earlier post), and now has provided more technical detail on the high-performance hybrid sports car and its new Sport Hybrid-AWD power unit.
At the core of this new hybrid power unit is a bespoke, mid-mounted twin-turbocharged, 75-degree 3.5-liter DOHC V6 engine with dry sump lubrication, mated to an all-new 9-speed dual clutch transmission (9DCT) and Direct-Drive Motor. This is augmented by the front Twin Motor Unit (TMU) driving the front wheels. The NSX Sport Hybrid power unit offers exceptional horsepower and torque with a broad powerband for tremendous throttle response and acceleration. Total system peak output is estimated at 573 horsepower—500 horsepower from the gasoline engine and 73 horsepower from the front TMU.
Argonne study finds lightweight material substitution increases vehicle-cycle GHGs, but results in total life-cycle benefit
October 12, 2015
A team at Argonne National Laboratory has taken a closer look at vehicle-cycle (all processes related to vehicle manufacturing) and vehicle total life-cycle (vehicle-cycle plus fuel cycle—i.e., the use phase) impacts of substituting lightweight materials into vehicles.
In a study published in the ACS journal Environmental Science & Technology, they reported that while material substitution can reduce vehicle weight, it often increases vehicle-cycle greenhouse gas emissions GHGs—for example, replacing steel with wrought aluminum, carbon fiber reinforced plastic (CRFP), or magnesium increases the vehicle-cycle GHGs. However, lifetime fuel economy benefits often outweigh the vehicle-cycle, resulting in a net total life-cycle GHG benefit, they found. This is the case for steel replaced by wrought aluminum in all assumed cases, and for CFRP and magnesium except for high substitution ratio and low fuel reduction value.

“Energy intensive industries, such as steelmaking, could see a 10 to 20 percent reduction in the cost of production, making products such as solar panels and chemical materials, such as plastics, as well as the cars and other products they go into, more affordable for American consumers,” said Energy Secretary Ernest Moniz. The goals of the Smart Manufacturing Institute are to:
New Mahle piston ring coating for high-output GTDI engines; chromium nitride using high-velocity oxygen fuel process
September 16, 2015
Mahle has developed a new thermal spray coating for modern high-output direct-injection turbocharged gasoline engines (GTDI). Under development since 2011 at Mahle’s thermal spray development labs in Michigan, the new process initially was designed for high-output GTDI engines currently in production by two US domestic automakers. The market for high-output turbocharged engines is expected to achieve a market share of 30% or more by 2020.
The new top ring coating, also referred to as MSC312, uses chromium nitride applied through a high-velocity oxygen fuel (HVOF) thermal spray process. MSC312 improves upon the scuff-and-wear capabilities of Mahle’s MSC385 chrome carbide HVOF coating because of the chromium nitride composition.

August 11, 2015
As part of its continuous optimization of production processes at its plants, the BMW Group is leveraging the opportunities arising from digitalization (i.e., “Industry 4.0”, earlier post). For the automotive manufacturer, digitalization opens up new perspectives with regard to the advancement of innovative and people-oriented production systems.
In turn, the freed potential in the production systems allows the company to respond even more individually to customers’ wishes and to step up the flexibility of the production chain.
Additive manufacturing company Carbon3D named Technology Pioneer by World Economic Forum; work with Ford
August 10, 2015
Additive manufacturing (3D printing) company Carbon3D Inc. was named one of the World Economic Forum’s 49 Technology Pioneers for 2015. Carbon3D joins the Technology Pioneers program as the first additive manufacturing company to be selected. Carbon3D recently emerged from stealth mode to introduce an innovative approach to polymer-based 3D printing that it says will advance the industry beyond basic prototyping to 3D manufacturing.
The new Continuous Liquid Interface Production technology (CLIP) uses a tuneable photochemical process instead of the traditional mechanical approach, eliminating the shortcomings of conventional layer-by-layer 3D printing technology, rapidly to transform 3D models into final parts in a range of engineering-grade materials. Ford has been working with Carbon 3D since December 2014, and has produced elastomer grommets for the Ford Focus Electric and damping bumper parts for the Transit Connect.
Ford working with OSU on sustainable alternative rubber sources for non-tire vehicle applications
August 06, 2015
While there are a number of efforts underway exploring the use of sustainable, natural rubber alternatives for use in tires (earlier post, earlier post, earlier post), cars use a great deal of rubber for non-tire applications as well; the Ford Fiesta, for example, contains about 3 kg of the material, excluding the tires.
Ford Motor Company is thus investigating alternative sustainable sources of rubber for automotive use in these non-tire applications. The company is working closely with The Ohio State University’s Ohio Agricultural Research and Development Center’s (OARDC’s) Program of Excellence in Natural Rubber Alternatives (PENRA) on researching the use of latex from guayule and Russian dandelion root in applications such as the car’s interior (cup holders), floormats, suspension bushings, engine mounts and so on, said Janice Tardiff, Elastomer Technical Expert at Ford.
Purdue team discovery could reduce energy required to machine annealed metals by >50%
July 28, 2015
Researchers at Purdue University have discovered a previously unknown type of metal deformation—sinuous flow—and a potentially simple method to suppress it. The results, reported in a paper in the Proceedings of the National Academy of Sciences (PNAS), could lead to more efficient machining and other manufacturing advances by significantly reducing the force and energy required to process metals by more than 50%.
Annealing is a heat-treatment process used to soften metals for machining. Counterintuitively, however, annealed metals are surprisingly difficult to cut, the Purdue team noted, involving high forces and an unusually thick “chip.” The conventional explanation for this anomaly has used a model of smooth plastic flow with uniform shear to describe material removal by chip formation. In their study, the Purdue team showed that the phenomenon is actually the result of a fundamentally different collective deformation mode: sinuous flow. Using in situ imaging, they found that chip formation occurs via large-amplitude folding, triggered by surface undulations of a characteristic size.
Renault-Nissan Alliance posts record €3.8 billion in synergies in 2014, up 32.4% from 2013; role of CMF
July 10, 2015
The Renault-Nissan Alliance posted record synergies of €3.80 billion ($4.25 billion) in 2014, up 32.4% from €2.87 billion the previous year. Purchasing, engineering and manufacturing were the biggest contributors. The launch of the Alliance’s first Common Module Family (CMF) vehicles (earlier post), as well as the recent convergence of four key functions—Engineering; Manufacturing Engineering & Supply Chain Management; Purchasing; and Human Resources—helped drive synergies in all three areas, said Carlos Ghosn, Chairman and CEO of the Renault-Nissan Alliance.
Synergies are generated from cost reductions, cost avoidance and revenue increases. Only new synergies (not cumulative) are taken into account each year. Accounting for synergies helps Renault and Nissan determine if they are meeting their performance objectives.
BMW and SCHERM put 40t battery-electric truck into service for material transport in 1-year pilot
July 06, 2015
The BMW Group and the SCHERM group have put a 40-ton electric truck for material transport into service on public roads in a one-year pilot. The truck, a Terberg YT202-EV electric tractor, has successfully completed its first test drives. The truck will travel a 2km route (1.2 miles) eight times a day between the SCHERM group logistics center and the BMW Group plant in Munich, transporting different vehicle components such as shock absorbers, springs and steering systems.
The truck battery takes three to four hours to charge. When fully charged, the vehicle has a range of up to 100 kilometers (62 miles). Thus, the electric truck can theoretically complete a full production day without any additional recharging.
Fraunhofer laser arc method enables diamond-like carbon coating at industrial scale at high rate; friction reduction
June 11, 2015
Fraunhofer researchers have developed a laser arc method with which layers of carbon almost as hard as diamond can be applied on an industrial scale at high coating rates and with high thicknesses. Applying such carbon coatings to engine components such as piston rings and pins contributes to lowering fuel consumption.
Carbon-based coatings are already used in volume production. But now the team of IWS researchers led by Prof. Andreas Leson from the Fraunhofer Institute for Material and Beam Technology IWS in Dresden, Dr. Hans-Joachim Scheibe and Dr. Volker Weihnacht has succeeded in producing hydrogen-free ta-C coatings on an industrial scale at a consistent level of quality. These tetrahedral amorphous carbon coatings are significantly harder and thus more resistant to wear than conventional diamond-like coatings.
Ricardo supporting Detroit Materials in commercialization of innovative lightweight steels

Ricardo Strategic Consulting, the global management consulting subsidiary of Ricardo plc, is providing support to start-up Detroit Materials (DM) for strategy and supply chain development to assist in the commercialization of its ultra-high performance structural materials into the automotive, truck and transportation sectors in support of structural lightweighting initiatives.
Detroit Materials has developed extremely strong, castable low-alloy steel. The DM steel offers the performance advantages of exotic-alloy steels (1300 MPa UTS, 16% elongation) with the ability to cast thin wall sections (3mm wall) and complex geometries at comparable cost per performance to ADI (Austempered Ductile Irons) and GJS ductile irons.
Researchers develop high-speed friction stir welding technique for aluminum joining at high volume production speeds
May 24, 2015
In partnership with General Motors, Alcoa and TWB Company LLC, researchers from the Department of Energy’s Pacific Northwest National Laboratory have developed a high-speed friction stir welding (FSW) process (earlier post) to join aluminum sheets of varying thicknesses—a key to producing auto parts that are light yet retain strength where it’s most needed—at speeds required for high volume production. The PNNL-developed process is ten times faster than current FSW techniques, representing production speeds that, for the first time, meet high-volume assembly requirements. The advancement is reported in an open-access paper in JOM, the member journal of The Minerals, Metals & Materials Society.
To create door frames, hoods and other auto parts, sheets of metal are welded together end-to-end into a “tailor-welded blank” (TWB) which is then cut into appropriate sizes before being stamped into the final shape. This process allows a high degree of customization. For example, a thicker gauge of metal can be used on one side of a car part, where extra strength is needed, joined via a weld to a thinner gauge on the side where it’s not.

May 22, 2015
Mercedes-Benz is investing a total of around €500 million (US$558 million) in its plant in Berlin—the Group’s oldest production facility in operation—which is being developed into a high-tech facility for component production. Some €150 million ($168 million) of that will be applied this year. In the future, Berlin will be a global center of competence for the production of the CAMTRONIC engine management system, giving it a unique position within the production network. The V6-cylinder diesel engine is produced in Berlin.
With the agreement of this transformation plan, the plant is continuing to push forward its development into a high-tech component manufacturing facility, focusing on the expansion of capacity for advanced products. In addition to high-precision transmission parts, camshaft adjusters and fuel systems, these include the CAMTRONIC valve timing system that will be the subject of the majority of the agreed investment.
Tesla posts $154M GAAP loss, $45M non-GAAP loss in Q1 on record deliveries; confident in 55K total deliveries this year
May 07, 2015
In its Q1 2015 financial report, Tesla Motors said it produced 11,160 vehicles in Q1 (10% better than guidance, at an average of 1,000 cars per production week); delivered 10,045 (worldwide), a quarterly record; and posted a $154-million GAAP net loss (non-GAAP net loss of $45 million). The Q1 GAAP net loss was 43% greater than the Q4 2014 GAAP net loss and 210% greater than GAAP net loss in Q1 2014.
Tesla has begun breaking out the revenues and costs of its automotive business from its other activities—i.e., powertrain sales, service revenue, Tesla Energy (the new line of stationary energy storage systems) and pre-owned Tesla vehicle sales. Automotive revenue and related costs reflect activities related to the sale or lease of new vehicles including regulatory (e.g., ZEV) credits, data connectivity and Supercharging.

April 20, 2015
|The winning design: “WaterBone”. Click to enlarge.|
Local Motors, in partnership with the Advanced Research Projects Agency-Energy (ARPA-E), announced the winner of the LIghtweighting Technologies Enabling Comprehensive Automotive Redesign (LITECAR) Challenge. The design challenge served to accelerate innovative ideas by using novel material technologies, structural designs, energy absorbing materials and unique methods of manufacturing to reduce vehicle curb weight while maintaining current US automotive safety standards. 254 conceptual designs were submitted. (Earlier post.)
The winning design, Aerodynamic Water Droplet with Strong Lightweight Bone Structure (“WaterBone”), was created by Andres Tovar, a mechanical engineering assistant professor at the School of Engineering and Technology at Indiana University-Purdue University Indianapolis, and his group of graduate students. The proposed design—which makes innovations in the structural layout, use of multi-materials, and the 3D printing manufacturing process—has the outer shape (envelope) of a water droplet with an embedded trabecular (graded porous) bone-like structure (spaceframe). The water droplet shape provides a low drag coefficient, while the spaceframe provides the mechanical strength and energy absorption capabilities (crashworthiness) required to protect the occupant in the event of a collision.
Carbon Core of next-gen BMW 7 Series helps reduce sedan’s weight by up to 130 kg; remote control parking
April 18, 2015
BMW presented an initial selection of technology highlights for the next generation of the BMW 7 Series model range featuring developments in lightweight design, driving dynamics, comfort, intelligent connectivity and operation.
Due to the BMW EfficientLightweight strategy, the new BMW 7 Series line-up will weigh up to 130 kilograms (287 lbs) less than the outgoing generation of models. At its heart is a body structure with a Carbon Core based on the transfer of technology from the development of the BMW i models. The use of CFRP for structural elements of the passenger cell based on hybrid construction with ultra-high-strength steels—such as the B-pillars—increases both the overall strength and the torsional and bending stiffness of the passenger cell. To this end, the configuration of sheet metal elements can be adjusted as required, allowing for a significant reduction in the weight of the body.

Cadillac CT6 mixed-material body structure saves 90 kg over predominantly steel construction
March 15, 2015
Cadillac will use an advanced mixed-material approach for the lightweight body structure of the upcoming CT6 range-topping full-size sedan, which will debut 31 March at the New York International Auto Show. The structure is aluminum-intensive, but the new Cadillac also includes 13 different materials customized for each area of the car to advance driving dynamics, fuel economy and cabin quietness; the mixed material approach saved 90 kg (198 pounds) compared to a predominately steel construction.
Sixty-four percent of the CT6 body structure is aluminum, including all exterior body panels. Thirteen complex high-pressure die cast components make up the lower structure of the CT6 body, along with aluminum sheets and extrusions. The vehicle underbody uses steel close-out panels on the lower structure to create a bank vault-quiet cabin without the added weight of extensive sound-deadening material, often used to compensate for aluminum panels in the occupant compartment.
Making the Mirai fuel cell vehicle
February 24, 2015
In Japan, Toyota Motor held a production ceremony at the Motomachi Plant, which first began production in 1959, to mark the production of the Mirai fuel cell vehicle, which the company launched in November 2014, and began selling in Japan in December 2014. (Earlier post.)
Motomachi has been home to some of Toyota’s most notable models, including the Publica, Corona, Cresta, Soarer, Supra, RAV4, and the Lexus LFA supercar. The former “LFA Works”—where craftspeople hand-built each of the 500 series limited Lexus supercars—is now the home of the Mirai. Toyota released a set of 5 short videos giving an overview of Mirai production, which delivers an estimated 3 units per day.
New human-robot cooperation in Audi’s final assembly processes
February 16, 2015
At its main plant in Ingolstadt, Audi has for the first time deployed a robot that works “hand-in-hand” with humans—without a safety barrier and ideally adapted to the employees’ working cycles. It is the first human-robot cooperation at the Volkswagen Group to be applied in final assembly. The technology makes work easier for the assembly employees and makes ergonomic improvements, the company said.
Formerly, employees of the A4/A5/Q5 assembly lines at Ingolstadt had to bend over material boxes to take out the coolant expansion tanks. This might seem a simple task, but with frequent repetitions it can lead to back problems. Now, however, the task will be taken over by a specialized KUKA robot, known internally as “PART4you” (Produktions-Assistent reicht Teil). (Volkswagen AG is increasingly working with Germany-based robot manufacturer KUKA; in late 2012, the Group awarded KUKA a contract for 6,000 robots for various plants—KUKA’s largest single blanket order.)
