Renault's Emblème concept, unveiled at the Paris Motor Show last October, represents a bold step in low-carbon mobility, serving as a "laboratory on wheels." The 4.8-meter-long estate vehicle is designed to emit 90% less CO2 equivalent than a 2019 petrol-powered Captur, according to a comprehensive life-cycle analysis. This reduction is achieved through a dual-energy system combining a battery with a hydrogen fuel cell range extender, ensuring minimal environmental impact while maintaining practicality.
The Emblème is more than a concept; it’s a detailed study in optimizing every aspect of vehicle design for sustainability. Seven key components—battery, steel, aluminum, polymers, electronic components, tires, and the hydrogen fuel cell system—account for 90% of its carbon footprint. Renault, alongside its EV division Ampere and over 20 partners, has scrutinized these elements to slash production emissions by 70%. For instance, the OPmobility hydrogen tank, made from carbon fiber, leverages low-carbon energy in its manufacturing process.
Battery technology is another focal point. The Verkor high-voltage battery claims a 72% reduction in carbon emissions compared to conventional equivalents, though specifics about its composition remain undisclosed. Renault has confirmed the battery will support ultra-fast charging, enhancing its appeal for everyday use. Meanwhile, advanced high-strength steels (AHSS) and press-hardenable steels (PHS) from ArcelorMittal reduce the vehicle’s weight by 8%, with recycled materials further cutting CO2 emissions by 69%.
Sustainable materials extend to the interior, where Forvia’s use of linen and pineapple fibers acts as a carbon sink. Even the headlights, designed by Forvia Hella, contribute to the vehicle’s eco-credentials by halving whole-life CO2 emissions. Adaptive interior lighting further reduces energy consumption by 60% in urban settings.
Renault’s Emblème concept underscores the automaker’s commitment to decarbonizing mobility, blending cutting-edge technology with meticulous attention to sustainability. While production details remain under wraps, the project sets a benchmark for future low-carbon vehicles.
