The LF-Ch is a concept four-door hatchback Lexus unveiled in September 2009 at the Frankfurt International Motor Show. The designation refers to Lexus Future-Compact hybrid. The LF-Ch exterior featured a more aggressive interpretation of the L-finesse design language, with an arching roofline, rear spoiler, and single-bar grille. The rear door handles were integrated into the C-pillar window trim. The concept was equipped with a hybrid 2.4 L inline-four gasoline engine with an electric motor. Inside, the LF-Ch featured wood, polished aluminum, and semi-aniline leather, along with paddle shifters, a turbine-style instrument panel, and Lexus' Remote Touch control interface with pop-up information screen. The rear seat featured entertainment options in the form of headrest-mounted iPhone docks. The LF-Ch was intended to preview a forthcoming premium compact vehicle, which was expected to enter production in the near future and targeted at European markets. Such a vehicle, originally codenamed C-Premium in early press reports, was designated CT 200h, CT 300h, or CT 400h in trademark applications filed in June 2009 in the US and in Canada. The LF-Ch concept measured 4,300 mm (169.3 in) long, 1,790 mm (70.5 in) wide, and 1,400 mm (55.1 in) in height, with a wheelbase of 2,600 mm (102.4 in). It may very well presumptively be a Lexus based on the Toyota Corolla.
