<P> Production models in development have included convertibles, crossovers, and dedicated hybrids . Under the F marque, Lexus plans to produce high - performance vehicles with its first expressions being the IS F and the LFA . Lexus officials have also discussed standard production model usage of varying platforms . The LS uses a dedicated platform, while the entry - level Lexus ES had been criticized for being too similar to the Toyota Camry, with which it shared platforms until its sixth generation, in both styling and powertrain design . The Nürburgring test track in Germany has also seen Lexus prototype testing . </P> <P> Lexus introduced a new design language known as "L - finesse" in the mid-2000s with its LF series concepts and the 2006 Lexus GS . L - finesse is represented by three Japanese kanji characters which translate as "Intriguing Elegance, Incisive Simplicity, and Seamless Anticipation". Design characteristics, including a fastback profile, lower - set grille, and the use of both convex and concave surfaces, are derived from Japanese cultural motifs (e.g. the phrase kirikaeshi in arrowhead shapes). While earlier Lexus models were criticized for reserved and derivative styling, and often mistaken for understated domestic market cars, automotive design analyses described L - finesse as adding a distinctive nature and embrace of Japanese design identity . Opinions varied for L - finesse's debut on the GS; Sports Car International's analysis praised the vehicle's in - person appearance; Automobile Magazine criticized the daring of its forward styling, and compared subsequent rival models for design similarities . In 2012, the arrival of the redesigned fourth generation Lexus GS featured the introduction of a spindle - shaped grille design, intended to be used on all forthcoming Lexus models . L - finesse exhibitions were presented at Milan's Salone del Mobile from 2005 through 2009 . </P> <P> The first Lexus vehicles were manufactured in Toyota's Tahara plant, a highly sophisticated, computerized manufacturing plant in Japan . Lexus production techniques include methods and standards of quality control that differ from Toyota models . At the Tahara plant, separate assembly lines were developed for Lexus vehicles, along with new molds and specialized manufacturing equipment . Welding processes, body panel fit tolerances, and paint quality requirements are more stringent . Lexus plant workers, typically veteran technicians, are identified via repeated performance evaluations and ranked according to skill grade, with limited applicants accepted . The highest level takumi (Japanese for "artisan") engineers are responsible for maintaining production standards at key points in the assembly process, such as testing engine performance . Production vehicles are given visual inspections for flaws, individually test - driven at high speeds, and subjected to vibration tests . </P> <P> Through the 2000s (decade), most Lexus sedan and SUV production has occurred in Japan at the Tahara plant in Aichi and Miyata plant in Fukuoka . In addition to the Tahara factory, Lexus vehicles have been produced at the Miyata plant (Toyota Motor Kyushu, Inc .) in Miyawaka, Fukuoka, Higashi Fuji plant (Kanto Auto Works, Ltd .) in Susono, Shizuoka, and Sanage plant (Toyota Boshoku Corp.; Araco) in Toyota City, Aichi . Front - wheel drive cars, such as the ES and HS, are produced in the Fukuoka Prefecture . The Kokura plant in Kitakyushu, Fukuoka, which opened in 2008, is a dedicated hybrid production site for Lexus models such as the gasoline - electric RX . The North American--market RX 350 (since the 2004 model year) is produced at the Cambridge plant (Toyota Canada, Inc .) in the city of Cambridge, in Ontario, Canada, which is the first Lexus production site located outside Japan . In late 2015, Lexus started to assemble North American - spec ES 350 sedans at the Georgetown plant (TMMK, Inc .). </P>
