Inside, the rally seats incorporate parts produced using 3D printing by ERPRO, marking the second known collaboration between Alpine and the French additive manufacturing specialist within the year.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\" dir=\"auto\" style=\"text-align: justify;\" data-sourcepos=\"7:1-7:439;492-930\">The one-off car is built on the A290 Rallye, the most performance-focused version of Alpine&#8217;s A290 and the platform the brand uses for customer racing. It is designed around a chassis optimized for rigidity, rally-specific suspension, widened tracks for grip, and aerodynamic work aimed at cooling and downforce. The electric powertrain is tuned for immediate torque delivery, a trait Alpine points to as an advantage in rally conditions.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\" dir=\"auto\" style=\"text-align: justify;\" data-sourcepos=\"9:1-9:263;932-1194\">Lacoste&#8217;s design contribution centers on a red-dominated cabin, drawing on the color of the crocodile logo&#8217;s tongue, along with petit piqu\u00e9 fabric on the seats and door panels, embroidered by workshop Potencier.<\/p>\n<p dir=\"auto\" data-sourcepos=\"9:1-9:263;932-1194\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-71391 aligncenter\" src=\"https:\/\/www.3dnatives.com\/en\/wp-content\/uploads\/sites\/2\/2026\/07\/2-2.jpg\" alt=\"\" width=\"700\" height=\"400\" srcset=\"https:\/\/www.3dnatives.com\/en\/wp-content\/uploads\/sites\/2\/2026\/07\/2-2.jpg 700w, https:\/\/www.3dnatives.com\/en\/wp-content\/uploads\/sites\/2\/2026\/07\/2-2-600x343.jpg 600w, https:\/\/www.3dnatives.com\/en\/wp-content\/uploads\/sites\/2\/2026\/07\/2-2-160x91.jpg 160w\" sizes=\"auto, (max-width: 700px) 100vw, 700px\" \/><\/p>\n<h2 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\" dir=\"auto\" style=\"text-align: justify;\" data-sourcepos=\"11:1-11:45;1196-1240\">Lattice Structures for Weight and Comfort<\/h2>\n<p class=\"font-claude-response-body break-words whitespace-normal\" dir=\"auto\" style=\"text-align: justify;\" data-sourcepos=\"13:1-13:482;1242-1723\">Within that cabin, the <a href=\"https:\/\/www.3dnatives.com\/en\/3d-printing-at-the-heart-of-automotive-interior-design-230120256\/\">rally seats<\/a> include components produced by ERPRO using 3D printing. According to Alpine, the technology enabled lattice-type structures, internal lattice geometries that reduce material use while distributing load across a network of interconnected struts, on the seat components. This allows the parts to combine lightness with comfort and structural performance, three properties that are harder to balance using conventional molded foam or machined parts.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\" dir=\"auto\" style=\"text-align: justify;\" data-sourcepos=\"15:1-15:300;1725-2024\">Weight reduction is a direct performance factor in rallying, where every kilogram affects acceleration, handling, and energy consumption in an electric vehicle. Alpine frames the seat components as part of a broader effort to cut mass across the one-off build rather than an isolated styling choice.<\/p>\n<p dir=\"auto\" data-sourcepos=\"15:1-15:300;1725-2024\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-71390 aligncenter\" src=\"https:\/\/www.3dnatives.com\/en\/wp-content\/uploads\/sites\/2\/2026\/07\/University-of-New-South-Wales-Sydney-1.jpg\" alt=\"\" width=\"700\" height=\"400\" srcset=\"https:\/\/www.3dnatives.com\/en\/wp-content\/uploads\/sites\/2\/2026\/07\/University-of-New-South-Wales-Sydney-1.jpg 700w, https:\/\/www.3dnatives.com\/en\/wp-content\/uploads\/sites\/2\/2026\/07\/University-of-New-South-Wales-Sydney-1-600x343.jpg 600w, https:\/\/www.3dnatives.com\/en\/wp-content\/uploads\/sites\/2\/2026\/07\/University-of-New-South-Wales-Sydney-1-160x91.jpg 160w\" sizes=\"auto, (max-width: 700px) 100vw, 700px\" \/><\/p>\n<h2 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\" dir=\"auto\" style=\"text-align: justify;\" data-sourcepos=\"17:1-17:57;2026-2082\">Alpine&#8217;s Second Collaboration with ERPRO in 2025-2026<\/h2>\n<p class=\"font-claude-response-body break-words whitespace-normal\" dir=\"auto\" style=\"text-align: justify;\" data-sourcepos=\"19:1-19:462;2084-2545\">This is not Alpine&#8217;s first use of ERPRO&#8217;s additive manufacturing capabilities. In <a href=\"https:\/\/www.3dnatives.com\/en\/alpine-a390_%ce%b2-show-car-070320255\/#!\">March 2025<\/a>, the automaker worked with the same partner on the Alpine A390_\u03b2 show car, where ERPRO 3D printed the headrests using a bio-based elastomer (Arkema&#8217;s Rebax Rnew), engineered to be lightweight, breathable, and shock-absorbent. That project also involved Lavoisier Composites, which produced the vehicle&#8217;s compression-molded carbon and photovoltaic-silicon floor panels.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\" dir=\"auto\" style=\"text-align: justify;\" data-sourcepos=\"21:1-21:216;2547-2762\">The repeat partnership suggests Alpine is treating 3D printing as a standing option for functional, low-volume interior components on concept and limited-run vehicles, rather than a one-time technical demonstration.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\" dir=\"auto\" style=\"text-align: justify;\" data-sourcepos=\"23:1-23:185;2764-2948\">Antony Villain, VP Design at Alpine, described the A290 Rallye collaboration as combining <em>&#8220;technicality of competition, the lightness of design and the elegance of timeless style.&#8221;<\/em><\/p>\n<p dir=\"auto\" style=\"text-align: justify;\" data-sourcepos=\"25:1-25:140;2950-3089\">What do you think of the collaboration?
