The LF-Ch is a concept four-door hatchback Lexus first unveiled in September 2009 at the Frankfurt International Motor Show. The designation refers to Lexus Future-Compact hybrid. The exterior featured an aggressive interpretation of the L design at the C pillar with an arching roofline complimented with a rear spoiler and the single-bar grille.

Bright LED taillights and headlamps add to the vehicle's personality. The concept is marked with hybrid details including its blue Lexus logo, which is shared across the Lexus family of hybrids, and hybrid side badging.

Inside, designers created an elegant cabin that is contemporary and functional with metal and leather trim. The LF-Ch has four sport seats that feature trim lighting along the cushion's edge for cabin illumination. Rear passengers can enjoy headrest-mounted iPhone® docking capability for audio and video entertainment.

A blue headliner light, that borders the roof and contrasts with the yellow exterior, turns on to reveal an ambient pattern reminiscent of a sophisticated lounge. A wide grip steering wheel with integrated paddle shifters makes for a spirited driving experience. The instrument panel features two, large twin dials with a uniquely embellished turbine blade design.

According to other reports, 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. It was originally codenamed C-Premium in earlier reports and was designated as 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).
