Akebono's NR22 Brake Caliper for Endurance Racing Achieves the Triple Crown of the World's Top Three Design Awards

Tokyo, Japan - (May. 9, 2023) - Akebono Brake Industry Co., Ltd. is pleased to announce that the NR22 brake caliper for endurance racing has received the Red Dot Award 2023 (organized by Red Dot GmbH & Co.KG of Germany) and the iF DESIGN AWARD 2023 (organized by iF International Forum Design GmbH of Germany). The NR22 has received four design awards, following the FY2022 Good Design Award (organized by Japan Institute of Design Promotion) and the International Design Excellence Awards 2022 (organized by the Industrial Designers Society of America).

The Red Dot Award and iF DESIGN AWARD, along with the International Design Excellence Awards, are the most prestigious design awards, regarded as "the world's top three design awards," and the NR22 has achieved the triple crown with winning all three.

The award-winning NR22 is a disc brake caliper for endurance racing that pursues an excellent balance between weight reduction and high durability. With a shape optimized by structural analysis, the caliper body component achieves a 7%*1 reduction in weight, while also achieving high durability, thereby realizing directness of brake operation. With a mirror-finish surface, the brake caliper is protected from radiant heat and can continue providing drivers with a stable brake feeling even under the high-temperature conditions found during endurance races that continue over long periods of time.

Reduction of automobile weight is a key element that influences such factors as dynamic performance and fuel consumption. For brake calipers used in racing, high durability is required as well as reduced weight. Achieving a balance between these at a high level will also contribute to enhancement of driver feeling.

This expertise is based on technology Akebono has cultivated in motor sports including Formula 1 and World Endurance Championships and has been put to effective use in creating a new method of structural analysis that works to achieve an excellent balance between durability and lightness of weight while also realizing a caliper body form styled according to the functional beauty of the racing car.

Features of the Award-Winning Product

1.Hydraulic flow path also used as strength member in cross-shaped rib structure that achieves an excellent balance between weight reduction and high durability

The shape is optimized using a newly devised method of structural analysis, and the ribs that cross above the cylinders function as more than just strength members. The rib interiors also serve as hydraulic flow paths, thereby efficiently achieving an excellent balance between weight reduction and high rigidity.

2.Mirror-finish plating prevents temperature rise from radiant heat and enhances heat resistance

By applying a mirror-finish plating to the surface, the caliper body is protected from temperature increase due to radiant heat. In addition to enabling use under high temperatures, this finish highlights the gently curved surfaces and sharp ridges, enhancing the design quality of the product exterior.

3.Optimal piston placement brings out 100% brake pad performance

The size and placement of each piston are optimized by means of proprietary technology for brake pad surface pressure analysis. This helps prevent uneven wear of brake pads and realizes both longer brake pad life and stable brake feeling in the prolonged harsh operating environment of endurance races.

Red Dot Award

Red Dot AwardThe Red Dot Award in Germany, which was founded in 1955, is known as one of the most prestigious design awards that indicates a quality of superior design and is considered as one of the world's top three design awards. The award is consisted of three competitions "Product Design," "Brands & Communication Design," and "Design Concept" for professional evaluation for diversity of design. The award is famous as the world's largest design award, with many entries from a variety of countries and regions each year.
