Toyota Racing Development (also known by its abbreviation TRD) is the in-house tuning shop for all Toyota and Lexus (and formerly Scion) cars. TRD is responsible both for improving street cars for more performance and supporting Toyota's racing interests around the world. TRD produces various tuning products and accessories, including performance suspension components, superchargers, and wheels. TRD parts are available through Toyota dealers, and are also available as accessories on brand-new Toyotas and Scions. Performance parts for Lexus vehicles are now labeled as F-Sport and performance Lexus models are labeled F to distinguish Lexus's F division from TRD.
As of there are two official branches of TRD: TRD Japan (a.k.a. Toyota Technocraft) and TRD USA. Each of these branches has both a performance tuning division and a race (or competition) division. In 2018, TRD Japan and Toyota Modellista merged to form Toyota Customizing & Development Co., Ltd (TCD).
TRD Japan's Race Division concentrates on the Super GT Series (JGTC), All-Japan Formula Three Championship Series, Esso Formula Toyota Series, and Netz Cup races (Vitz and 86/BRZ Race Series). Many of these activities has been rebranded under the Toyota Gazoo Racing brand, following the merger of TRD Japan into TCD banner.
TRD USA's Race Division, known as 'Toyota Gazoo Racing North America', competes in NASCAR, NHRA
