EuroCarBody Award 2015 goes to the Carbon Core body of the new BMW 7 Series
November 12, 2015
The Carbon Core body structure of the new BMW 7 Series has been awarded the EuroCarBody Award 2015 at the 17th Global Car Body Benchmarking Conference. The body of the new BMW luxury sedans was given a rating of 41.87 out of 50 possible points—the best score ever to be obtained in this competition. The EuroCarBody Award has been announced at the annual conference of experts every year since 2002 and is regarded as a leading award for innovations in car body construction.
The Carbon Core used for the body structure is the central element of the BMW EfficientLightweight Technology that was applied particularly consistently in the development of the sixth generation of the BMW 7 Series. For the first time in a volume-production automobile, a composite of CFRP, aluminium and super high-strength steels was created which increases rigidity and stiffness in the passenger cell while at the same time significantly reducing the vehicle weight.
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.
Alcoa splitting into two companies; expecting 2.4x increase in automotive revenues to $1.8B in 2018
September 28, 2015
The Board of Directors of Alcoa has unanimously approved a plan to split the lightweight metals leader into two independent, publicly-traded companies. The globally competitive Upstream Company will comprise five business units that today make up Global Primary Products: Bauxite, Alumina, Aluminum, Casting and Energy.
The Value-Add Company will include Global Rolled Products, Engineered Products and Solutions, and Transportation and Construction Solutions. The transaction is expected to be completed in the second half of 2016. At that point Alcoa shareholders will own all of the outstanding shares of both the Upstream and Value-Add Companies. The separation is intended to qualify as a tax-free transaction to Alcoa shareholders for US federal income tax purposes.

New Opel Astra up to 441 lbs lighter than predecessor
August 27, 2015
The new Opel Astra, which makes its debut in several weeks at the IAA in Frankfurt, will be up to 200 kg (441 lbs) lighter than its predecessor (120 kg / 265 lbs at a minimum). The next generation of the compact bestseller is based on an all-new lightweight architecture, with a slimmer body and all-aluminum engines.
The Monza Concept presented at the 2013 IAA (earlier post) was the role model for Opel’s eleventh compact class generation. The new Astra features a slimmed down vehicle architecture: the bodyshell (body-in-white) and structure alone are more than 20 percent lighter, down from 357 to 280 kilograms (787 to 617 lbs). Another 50 kilograms (110 lbs) were saved in the design of chassis components: high-strength and ultra-high-strength lightweight steels, more compact subframes as well as modification to the front and rear suspensions all contributed to this end result.

August 07, 2015
Ford Motor Company was the winner of the 3rd annual Altair Enlighten Award for its use of various lightweight materials to minimize weight of the 2015 Ford F-150. The Enlighten Award is the automotive industry’s first award program created specifically to acknowledge innovation in vehicle weight reduction.
Ford’s entry, one of 17 nominations that competed for the award, was selected as the winner for taking 700 pounds (318 kg) off of the Ford F-150 while improving its performance, safety, and efficiency. (Earlier post.) Ford engineers took a holistic approach to weight reduction by incorporating advanced materials into the entire design of the vehicle, including the frame, body, powertrain, battery and interior features such as the seats. The weight savings help the truck tow more, haul more, accelerate quicker and stop shorter, and it contributes to fuel efficiency.
GM using Continental Structural Plastics’ TCA Ultra Lite in Corvette for 20 lb weight savings
July 22, 2015
Continental Structural Plastics (CSP), a global provider of lightweight composite solutions, announced that its Tough Class A (TCA) Ultra Lite material, introduced in September 2014, is now in production on the 2016 Chevrolet Corvette. The use of TCA Ultra Lite, a Class A body panel material, results in a 20 lb (9 kg) weight savings on the Stingray Coupe model. This is the first production use of CSP’s Ultra Lite advanced composite.
Ultra Lite technology uses treated glass bubbles to replace some of the CaCO3 (calcium carbonate) filler, allowing the resin to adhere to the matrix and increase the interfacial strength between the bubble and the resin. This is a patented treatment technology that results in a more robust resin mix that makes molded parts more resistant to handling damage, and prevents the micro-cracks that cause paint pops, pits and blistering. The treated bubbles also help with paint adhesion and bonding characteristics.
China Zhongwang and Brilliance Bus partner to develop all-aluminum new energy public buses
July 20, 2015
China Zhongwang Holdings Limited, the second largest industrial aluminum extrusion product developer and manufacturer in the world and the biggest one in Asia, has successfully designed, manufactured and developed all-aluminum new energy electric buses for Brilliance Bus (Dalian) Company Limited. This co-operation marks China Zhongwang’s inauguration as the first and only aluminum processing enterprise in China to have the capability of undertaking both the design and manufacturing of all-aluminum new energy public buses.
The frame and body of this new public bus model use aluminum alloy as the key material. Its weight is reduced by 40% compared to its steel counterparts. Aluminium-bodied vehicles are more durable, corrosion resistant and have better vibration absorption capabilities. The lighter auto bodies increase the vehicles’ driving range, thereby conserving energy and reducing operating costs.
Syntactic foam composite for lightweight yet strong materials; bending strength for automotive applications
July 17, 2015
A team of researchers reports success in pioneering tests of a layered material with a lightweight metal matrix syntactic foam core that holds significant potential for automobiles, trains, ships, and other applications requiring lightweight structural components that retain their strength even when bent or compressed. (Syntactic foams are materials with pre-formed hollow spheres as a main constituent. “Syntactic” refers to the “ordered structure” provided by the hollow spheres.)
The research team of Nikhil Gupta, a NYU School of Engineering associate professor in the Department of Mechanical and Aerospace Engineering, working with the Toledo, Ohio, company Deep Springs Technology and the US Army Research Laboratory, published their findings in Materials Science and Engineering: A.
Ford’s first mass-produced carbon fiber wheels
July 12, 2015
To source the new lightweight track-capable carbon fiber wheels that are standard on the new Shelby GT350R Mustang, Ford partnered with Australia-based Carbon Revolution. Carbon Revolution first began delivering composite wheels in 2004 for Formula SAE campaigns. The company now is producing its “CR-9” wheel series in limited numbers for Porsche, BMW M3, Audi R8, Lamborghini and McLaren MP4-12C within Europe, Japan and North America. Ford, however, wanted more of a mass-production solution.
The one-piece carbon fiber wheels for the Mustang weigh nearly half that of an equivalent aluminum wheel (18 pounds versus 33 pounds), and handling and acceleration performance see serious benefits. The wheels also provide a reduction in rotational inertia of more than 40%, which positively impacts acceleration and braking performance. The wheels are so light, the springs and MagneRide dampers had to be recalibrated because the suspension can respond considerably faster to road inputs.
Toho Tenax’s prepreg helps to cut 1.1MW Tajima Rimac electric racer’s weight
June 22, 2015

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.
Solvay participating in Polimotor 2 carbon fiber reinforced polymer engine project
May 19, 2015
Solvay is taking a “leadership role” in the development of the Polimotor 2 all-plastic automotive engine to be tested in a race car next year, demonstrating the company’s advanced specialty polymer technologies in light-weighting through metal replacement. The collaborative project is intended ultimately to set the stage for innovative breakthroughs in future commercial automobiles.
The original Polimotor was developed by Matti Holtzberg in the 1980s. The first version of the Polimotor, based on the Ford 2.3L Mustang engine, used a combination of carbon fiber, Torlon, epoxy, ceramic and metal. The engine block, cylinder head, valve spring retainers, timing gear intake valves and several other parts were made of fiber reinforced composites (FRCs). The reciprocating mass was still metal.

With a clamping force of 36,000 kN, the ENGEL v-duo 3600 is the largest machine in its series. One machine in the same clamping force class is installed at BMW’s Landshut factory, where large structural components of fibre-reinforced plastic composites are manufactured using the HP-RTM process.
“WaterBone” design wins grand prize in ARPA-E LITECAR Challenge
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.

March 26, 2015
BASF and Floatility have partnered for the development of an ultra-lightweight and solar-powered electric scooter. Weighing less than 12 kilograms (26.5 lbs) and consisting of more than 80% composite and plastic materials from BASF, the scooter will give commuters the sensation of floating and thus has been named ‘e-floater’. The e-floater is designed to bridge the gap on the last mile between home or city center and the nearest public transport.
BASF will provide versatile plastic materials and support the project with its extensive development capabilities. Molding multiple parts to create complex shapes with plastic materials enables design freedom and the streamlined construction of the ‘e-floater’.
DOE announces conditional commitment for $259M loan to Alcoa for automotive aluminum production
The US Department of Energy (DOE) announced a conditional commitment for a $259-million loan to Alcoa Inc. If finalized, the loan would support the company’s Alcoa, Tennessee, manufacturing facility (Tennessee Operations), where the company will produce high-strength aluminum for North American automakers looking to lightweight their vehicles. (Earlier post.)
This conditional commitment is the first issued by the Department under the Advanced Technology Vehicles Manufacturing (ATVM) loan program since Secretary Moniz announced a number of improvements to the program last year, and is the first step toward issuing a final loan to Alcoa.
DeltaWing to develop GT race car concept; step toward street-legal DeltaWing sports car
March 23, 2015
DeltaWing Technology Group is beginning development of a DeltaWing GT race car concept. The racer will be designed to demonstrate that with far less horsepower than many of today’s best sports cars, a two-seat performance car based on the DeltaWing architecture would deliver the same performance, yet with previously unattained fuel economy and efficiency. Expected to appear in 2015, this new DeltaWing Racing Cars project is a major step toward a street-legal two-seat DeltaWing sports car, the company said.
In Mat 2014, DeltaWing released a rendering of an application of its DeltaWing aerodynamic and lightweight design architecture as a street-legal, four-passenger car. DeltaWing Technologies said at the time that it was seeking OEM partners with the ultimate goal of licensing the DeltaWing vehicle architecture that is 35% lighter, requires 35% less horsepower, and consumes 35% less fuel. (Earlier post.)
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.
POSTECH researchers develop new high-strength, lightweight steel
February 27, 2015
Researchers at Pohang University of Science and Technology (POSTECH) in South Korea have developed a new type of steel with improved tensile strength and lightness. In their approach, they effectively utilized a brittle intermetallic compound (B2) that metallurgists usually try to suppress by modifying B2 morphology and dispersion in the steel matrix.
The specific tensile strength and ductility of the developed steels improve on those of the lightest and strongest metallic materials known, titanium alloys, the researchers said. The results, reported in a paper in the journal Nature, demonstrate how intermetallic compounds can be harnessed in the alloy design of lightweight steels.
Magna unveiling lightweight plug-in hybrid sportscar at Geneva show
Global automotive supplier Magna International Inc. will debut MILA Plus, an two-seat plug-in hybrid sports car, at the upcoming Geneva Motor Show. The lightweight (1,520 kg, 3,351 lb) concept vehicle, the latest member of the MILA family of concept vehicles (earlier post), offers an all-electric range of 75 km with reduced CO2 emissions of 32g/km.
System power output is 200 kW (272 hp), with 580 N·m of peak torque. The MILA Plus accelerates from 0-100 km/h in 4.9s; electric acceleration from 0-80 km/h takes 3.6s. The performance of the three-cylinder gasoline engine is enhanced by the addition of two electric motors—one between the internal combustion engine and transmission to drive the rear axle, and one on the electric front axle. This arrangement results in an electric all-wheel-drive system which transmits more torque to the road and results in improvement of vehicle maneuverability and dynamics.
Lux: carbon fiber to go mainstream in automobiles by 2025
February 22, 2015
Driven by a faster-than-expected pace of technology development, carbon-fiber reinforced plastics (CFRPs) will be poised to gain widespread adoption for automotive lightweighting by 2025, according to a new report from Lux Research, “Scaling Up Carbon Fiber: Roadmap to Automotive Adoption.”
Advances already underway in fiber, resin and composite part production will lead to a $6 billion market for automotive CFRPs in 2020, more than double Lux’s earlier projection. (Earlier post.) Even this figure is dwarfed by the full potential for CFRPs in automotive if they can become affordable enough for use in mainstream vehicles, Lux posits.

Researchers suggest hybrid graphene oxide/cellulose microfibers could supersede carbon fibers
January 16, 2015
Researchers from Nanjing Forestry University and the University of Maryland have designed high-performance microfibers by hybridizing two-dimensional (2D) graphene oxide (GO) nanosheets and one-dimensional (1D) nanofibrillated cellulose (NFC) fibers. The resulting well-aligned, strong microfibers have the potential to supersede carbon fibers due to their low cost, the team suggests in an open access paper published in the journal NPG Asia Materials.
The hybrid microfibers are much stronger than microfibers composed of 1D NFC or 2D GO alone. In their paper, they reported that experimental results and molecular dynamics simulations reveal the synergistic effect between GO and NFC: the bonding between neighboring GO nanosheets is enhanced by NFC because the introduction of NFC provides the extra bonding options available between the nanosheets.

Johnson Controls and its partners are working to reduce the use of metals in vehicle seat structures by replacing them with multi-material systems in the CAMISMA (carbon-amide-metal-based interior structure using a multi-material system approach) research project. (Earlier post.)
The company is displaying the CAMISMA seat prototype, which achieves a more than 40% weight reduction against conventionally manufactured seat structures without compromising safety properties, at the 2015 North American International Auto Show (NAIAS) in Detroit. Johnson Controls received this year’s CLEPA (European Association of Automotive Suppliers) Innovation Award in the “Green” category for this work. According to the jury, the project represents an “outstanding, future-oriented solution for sustainable carbon dioxide reduction.”
Ford puts the pedal down on performance … but not with electric drive technology right now
January 14, 2015
|The new Ford GT on display in the Ford stand at NAIAS. Click to enlarge.|
In December, Ford President and CEO Mark Fields said Ford would focus on five key areas of innovation, one of them being performance. He said that more than 12 new performance vehicles would be introduced through 2020. (Earlier post.) At the North American International Auto Show (NAIAS) in Detroit this week, Ford delivered first proof of that focus with the reveal of the new Ford GT carbon-fiber supercar, as well as the new F-150 Raptor based on the new aluminum F-150 and the Shelby GT350R Mustang.
The stunning Ford GT—which received the EyesOn Design Award at NAIAS for best production vehicle—serves as a technology showcase for top EcoBoost engine performance, aerodynamics and lightweight carbon fiber construction. Beginning production late next year, the GT will the road in select global markets in honor of the 50th anniversary of Ford GT race cars placing 1-2-3 at the 1966 24 Hours of Le Mans. However, unlike today’s hybrid drive Le Mans racers, or the new Acura NSX hybrid supercar, also revealed at NAIAS (earlier post), the GT—nor any of the other Ford performance vehicles unveiled at NAIAS—makes no use of electric drive technology.
ASG life-cycle study finds aluminum Ford F-150 “Best Full-size Truck of 2015” from environmental and economic perspective
According to the latest annual life-cycle study from the Automotive Science Group (ASG), the all-new lightweight aluminum 2015 Ford F-150 leads the full-size light-duty truck competition in all environmental and economic performance areas; accordingly, ASG selected the F-150 as its Best Full-size Truck of 2015. According to ASG and the principles of ecological economics, environmental and economic considerations are equally important in determining a vehicle’s overall value. ASG’s proprietary vehicle rating platform—the Automotive Performance Index—analyzes both performance areas for a comprehensive vehicle assessment. ASG’s 2015 Study assessed 225 light-duty truck models.
Although the gasoline-fueled F-150 with 2.7L EcoBoost delivers 22 mpg (10.68 l/100 km) combined—1 mpg shy of RAM’s EcoDiesel—the F-150’s life-cycle environmental and economic performance “leaves RAM and others in the dust,” according to ASG. According to ASG, the 2015 F-150 holds the smallest life-cycle carbon footprint and lowest cost of ownership of any full-size truck in the North American market today. Ford has produced a lightweight aluminum-intensive truck that costs less and performs better than its conventional truck counterparts over the vehicle’s life-cycle, says Colby Self, managing director of ASG.
University of Tennessee to head $250M advanced composites manufacturing institute; Ford, Honda and Volkswagen members
January 09, 2015
The Department of Energy and a consortium of 122 companies, nonprofits, and universities led by the University of Tennessee-Knoxville will invest more than $250 million—$70 million in federal funds and more than $180 million in non-federal funds—to launch a Manufacturing Innovation Institute for Advanced Composites—the fifth institute to be awarded of the eight national institute competitions launched earlier (earlier post).
The new Institute for Advanced Composites Manufacturing Innovation (IACMI), announced today by President Obama, will focus on advanced fiber-reinforced polymer composites that combine strong fibers with tough plastics to yield materials that are lighter and stronger than steel. While advanced composites are used in selective industries such as aircraft, satellites and cars, these materials remain expensive, require large amounts of energy to manufacture and are difficult to recycle. IACMI is dedicated to overcoming these barriers by developing low-cost, high-production, energy-efficient manufacturing and recycling processes for composites applications.
ARPA-E issues $125M open solicitation for energy R&D; transportation and stationary applications
January 07, 2015
The US Department of Energy (DOE) Advanced Research Projects Agency - Energy (ARPA-E) has issued a $125-million open Funding Opportunity Announcement (FOA). OPEN 2015 (DOE-FOA-0001261) will support the development of potentially disruptive new technologies in all areas of energy research and development, for both transportation and stationary applications.
OPEN 2015 is the third open funding solicitation issued by the agency. Open solicitations ensure that ARPA-E does not miss opportunities to support potentially transformational projects outside the scope of existing ARPA-E programs. The projects selected under OPEN 2015 will pursue novel approaches to energy innovation and support the development of potentially disruptive new technologies across the full spectrum of energy applications.
New high-entropy alloy is as light as aluminum, stronger than titanium alloys
December 11, 2014
Researchers from North Carolina State University and Qatar University have developed a new high-entropy alloy that has a higher strength-to-weight ratio that they say is unmatched by any other metallic material. The researchers used mechanical alloying to combine lithium, magnesium, titanium, aluminum and scandium to make a low-density, nanocrystalline alloy (Al20Li20Mg10Sc20Ti30) with an estimated strength-to-weight ratio that is significantly higher than other nanocrystalline alloys and is comparable to ceramics. An open access paper on their work is published in the journal Materials Research Letters.
High-entropy alloys (HEAs) are a new class of multi-component alloy systems in which the design of the alloys is based not on adding to a single base element, but on choosing elements that will form solid solutions when mixed at near-equiatomic concentrations. (Earlier post.) HEAs

A lightweight multi-functional crankshaft cover in Royal DSM’s EcoPaXX high-performance polyamide 410 was top in the Powertrain category at the Society of Plastics Engineers Automotive Division Innovation Awards Competition and Gala in Detroit. The 70% bio-based EcoPaXX is made principally from topical castor beans and is 100% carbon neutral from cradle to gate. Castor oil is obtained from the Ricinus Communis plant, which grows in tropical regions on relatively poor soil, and does not compete with the food-chain.
The EcoPaXX crankshaft cover is produced by DSM’s automotive component specialist partner KACO in Germany for the latest generation of MDB-4 TDI diesel engines developed by the Volkswagen Group. The engines are fitted to various car models made by VW, Audi, Seat and Škoda. Dr. Lutz Wohlfarth from Volkswagen, and Marcio Lima from KACO were both at the Gala in Detroit to collect the SPE award.
