The automotive industry’s quest for sustainability is taking a surprising turn. At next month’s SPE Automotive Composites Conference & Exhibition (ACCE), keynote speaker Casey Putsch—a renowned engineer, racer, and YouTube personality—will present groundbreaking research on composite-material vehicles that reportedly achieve a lower carbon footprint than Tesla’s best-selling electric cars. The event, hosted by the Society of Plastics Engineers (SPE), promises to challenge conventional wisdom about emissions by spotlighting internal combustion engine (ICE) vehicles built with advanced composites that outperform EVs in lifecycle CO2 assessments.
The Composite Advantage: Lighter, Cleaner, and More Efficient
Putsch, whose YouTube channel blends high-octane racing content with deep dives into automotive innovation, is expected to argue that lightweight composite materials—such as carbon-fiber-reinforced polymers—could redefine sustainability in transportation. Unlike traditional steel or aluminum, composites reduce vehicle weight by up to 50%, drastically improving fuel efficiency for ICE cars. But the real breakthrough lies in their manufacturing process.
According to a recent study highlighted by Plastics Today, these composites are now being produced using renewable energy and recycled materials, slashing the carbon intensity of production by 30% compared to conventional methods. When combined with cleaner-burning synthetic fuels or hybrid systems, composite ICE vehicles could emit less CO2 over their lifetime than a Tesla Model 3 charged on a grid reliant partly on fossil fuels.
Beating Teslas on Lifetime Emissions: How It’s Possible
While Tesla’s EVs produce zero tailpipe emissions, their overall environmental impact depends heavily on battery manufacturing and electricity sources. Composite ICE vehicles sidestep the battery issue entirely. “We’re seeing a scenario where the emissions saved by avoiding resource-intensive battery production, paired with ultra-efficient composites, give ICE cars a fighting chance,” Putsch explained in a preview of his ACCE talk.
The data underscores this: A composite-intensive ICE sedan could emit 45 tons of CO2 over 150,000 miles, compared to 50 tons for a Tesla Model 3 in regions where coal dominates the energy mix. Even in areas with cleaner grids, the gap narrows significantly—a revelation that’s sparking debate among automakers.
Event Details and Industry Implications
The SPE ACCE conference, scheduled for September 10–12 in Novi, Michigan, will feature panels on material science, recycling, and policy. Industry leaders from Ford, BMW, and BASF are slated to attend, with many eyeing composites as a bridge technology while EV infrastructure matures.

A New Path Forward—or a Niche Solution?
Critics argue that composites remain expensive and energy-intensive to produce, limiting their scalability. Yet proponents counter that as recycling technologies advance, these materials could become a staple in both ICE and electric vehicles. “This isn’t about ICE vs. EV,” Putsch emphasized. “It’s about using innovation to cut emissions now, not in 2035.”
Whether composite cars become mainstream or remain a footnote, one thing is clear: The road to sustainability just got more interesting.
