The Automotive Division of the Society of Plastics Engineers (SPE, Danbury, Conn., U.S.) has announced the winners for its 51st annual Automotive Innovation Awards Gala, previously revealed during the Nov. 2, 2022 event held at the Burton Manor in Livonia, Mich., U.S.
The Chassis/Hardware category winner was this year’s Grand Award winner. The Grand Award winner is selected from the winners of each of the 10 categories by a panel of industry-expert Blue Ribbon Judges. This year’s winners are:
Category Winner: Additive Manufacturing
Spoiler Closeout Seal
- OEM make and model: 2022 General Motors Co. Chevrolet Tahoe, Chevrolet Suburban, Cadillac Escalade, GMC Yukon
- Tier supplier/processor: HP Inc. and AMT Ltd./GKN Additive (Forecast 3D)
- Material supplier/toolmaker: BASF Corp./GKN Additive
- Material/process: BASF SE Ultrasint TPU01 thermoplastic polyurethane (TPU)/HP Multi Jet Fusion 5200 Series
The powder bed fusion (PBF) process was used to source, print, process and install 60,000 TPU spoiler closeout seals to meet 10 weeks of production as a bridge solution while hard tooling was being produced. Innovative vapor polishing and drying processes cleared a bottleneck, halved production time, were used to finish parts, eliminating the need for post-print dyeing. The seals close out gaps on left and right sides of rear spoiler, improving finish and fuel efficiency.
Category Winner: Aftermarket and limited edition/specialty vehicles
Carbon Fiber C-Brace
- OEM make and model: 2022 Ford Motor Co. Ford Bronco Raptor
- Tier supplier/processor: Montaplast of North America
- Material supplier/toolmaker: BASF Corp./Commercial Tool Group
- Material/process: Ultramid B3WC4 HP CF and GR PA6/injection molding

This customer-visible, Class A C-brace was designed to meet offroad desert durability requirements for convertible versions of the vehicle while boosting torsional stiffness 40% to improve handling and NVH. Weight was reduced 55% versus aluminum and 85% versus steel by adopting a sandwich composite approach. Upper and lower shells were injection molded in 35% GR PA6 while a core was injection molded in 20% CF-PA6, then components were bonded with a newly formulated methacrylate adhesive.
Category Winner: Body Exterior
Panoramic Sunroof Frame
- OEM make and model: 2022 Hyundai Motor Group Kia Sorento
- Tier supplier: Inalfa Roof Systems Korea
- Material supplier: GS Caltex Corp.
- Material/process: Hiprene ALG14BF PA6/injection molding
Several novel technologies contributed to this large injection-molded LFT-PA6 panoramic sunroof frame. First, flat rather than round glass fibers provided higher dimensional stability and reduced warpage. Second, the twist pultrusion was used to produce long fiber-reinforced thermoplatic (LFT) pellets whose fiber length exceeds the length of the pellets, again contributing to mechanical improvements. Weight was reduced 51% and part count dropped from 33 to four versus a steel frame. Compared to carbon fiber-reinforced LFT, torsional rigidity was 13% higher and breaking force 25% optimized at 24% lower cost.
Category Winner: Body Interior
Second Row Seat Backs and Cushions
- OEM make and model: 2022 Toyota Motor Corp. Toyota Tundra
- Tier supplier/processor: Flex-N-Gate Corp. and Adient/Flex-N-Gate Corp. and L&L Products
- Material supplier/toolmaker: BASF Corp./SyBridge Technologies
- Material/process: Ultramid B3ZG7 35% GR-PA6 and Elastocoat 74850 80% GR-PUR PA6 and PU/pultrusion and injection overmolding

This composite seat structure combines a pultruded continuous fiberglass-reinforced polyurethane (PUR) reinforcement beam that is injection overmolded with short glass/PA6 to form the seat frame geometry. By replacing a 60-piece high-strength steel frame structure with a four-piece molded composite structure, significant crash performance improvements were achieved while both cost and mass targets of 20% reduction were met. Additionally, more than 100 welds at 16 weld stations were eliminated, improving quality control and under-seat storage that wasn’t possible with the previous solution was added.
Category Winner: Electric and Autonomous Vehicle Systems
High-Voltage Power Distribution System
- OEM make and model: 2022 Ford F-150 Lightning
- Tier supplier/processor: Aptiv PLC/Yazaki North America Inc.
- Material supplier: DuPont de Nemours Inc.
- Material/process: Crastin FR684 and HR5339 PBT/injection molding, silicone overmolding
This customizable, shielded high-voltage power distribution system permits seven sets of subassemblies and up to 64 possible configurations from a single tool, providing both flexibility and scalability for future programs. Three different materials are used: A flame retardant 25% GR-PBT forms the internal assembly and terminal blocks and a silicone seal is overmolded directly onto a 30% GR-PBT cover. A unique shielding system uses stamped connection interfaces that reduce mass by two-thirds versus cast products while maintaining electromagnetic shielding.
Category Winner: Powertrain
High-Pressure Oil Cooler Gasket Seal
- OEM make and model: 2022 General Motors Co. Chevrolet Silverado and GMC Sierra
- Tier supplier/processor: Uchiyama Marketing & Development America LLC
- Material supplier/toolmaker: Uchiyama Marketing & Development America LLC and DuPont de Nemours Inc./Uchiyama Marketing & Development America LLC
- Material/process: UMC V7401 Ethylene Acrylic Elastomeric Plastic/injection molding
Oil cooler gaskets are small parts with important sealing functions between oil coolers and oil pumps in demanding engine environments. To eliminate leaks seen with fluorocarbon seals during temperature cycling, a new ethylene acrylic TPV was developed. It offers low-temperature sealing and maintains good compression set and controlled oil swelling from -40° to 150°C and 14 bars oil pressure. Gasket height also was increased to provide higher contact pressure and better sealing. Costs were reduced 66% and sustainability was increased since the thermoplastic material is recyclable.
Category Winner: Sustainability
Reclaimed TPO/Foam System
- OEM make and model: 2020 General Motors Co. Chevrolet Silverado and GMC Sierra
- Tier supplier/processor: Inteva Products LLC
- Material supplier: Inteva Products LLC
- Material/process: Inteather TGTPO ECO TPO/extrusion and repellitizing; co-extrusion of TPO sheets; vacuum forming and injection graining; press lamination; and assembly
Thanks to a patented recycling process, PIR bilaminate scrap comprised of TPO skins attached to cross-linked olefin foam is given new life in the same interior trim applications without sacrificing quality or performance. An additive package eliminates/binds/deactivates reactive residuals and trapped gases from foam. Just on this program, 680,389 kilograms of TPO resin is reclaimed annually, reducing landfilled scrap 93%, replacing 50% of prime TPO and lowering CO2 emissions and energy use by 48% each.
Category Winner: Vehicle Engineering Team Award (VETA)

- Materials Finalist: Dual Cordset EV Charger Lens
- Materials Finalist: Thermal Management Tube & Connector Solution
- Materials Nomination: Center Frame Panel
- Process/Assembly/Enabling Technology Nomination: Elastic Averaging Vehicle Attachment
- Sustainability Nomination: Recycled Resin Blow Molded Ducts
Category Winner: Hall of Fame Award
What is said to be the first mold in color (MIC) weatherable grille, used on the 1987 Volkswagen Golf, has been named the 2022 Hall of Fame Winner. The MIC weatherable grille, made possible with Luran S ASA from Ineos Styrolution (precolored plastic resins used in the plastic injection molding process so the molded part emerges in a specific color and finish), proved to be a game-changer for vehicle front grilles by providing a weatherable, paint free exterior surface.
To be considered for a Hall of Fame Award, an automotive plastic or composite component must have been in continuous service in some form for at least 15 years and broadly adopted in the automotive industry. This application certainly qualifies, as MIC grilles have become the industry standard used by every major OEM for front grilles replacing traditionally painted materials on more than 300 million exterior parts including grilles, mirrors, pillars, spoilers, fog bezels and more. Further technology now being developed around MIC ASA includes radar detection covers, lidar equipment and center high mounted stop lamp (CHMSL) bezels.
The companies involved in developing the MIC weatherable grille application include:
- OEM: Volkswagen Group
- Molder/processor: Volkswagen Group
- Material supplier: Ineos Styrolution.
Representatives from these companies accepted the SPE Automotive Hall of Fame Award, on behalf of the original team that worked to develop the technology.
