Lexus HS
The Lexus HS (Japanese: レクサス・HS, Rekusasu HS) is a dedicated hybrid vehicle introduced by Lexus as a new compact executive car sedan in 2009. Built on the Toyota New MC platform, it is classified as a compact under Japanese regulations concerning vehicle exterior dimensions and engine displacement. Unveiled at the North American International Auto Show in January 2009, the HS 250h went on sale in July 2009 in Japan, followed by the United States in August 2009 as a 2010 model. The HS 250h represented the first dedicated hybrid vehicle in the Lexus lineup, as well as the first offered with an inline-four gasoline engine. Bioplastic materials are used for the vehicle interior. With a total length of 4,700 mm (190 in), the Lexus HS is slightly larger than the Lexus IS, but still smaller than the mid-size Lexus ES.
Like the smaller Lexus CT, the larger Lexus ES and the Lexus RX FWD (which has also shared the same production line), the HS features front-wheel drive, and as such has been offered as IS's front-wheel drive counterpart. In the U.S., sales for the HS 250h lagged other models, and dropped by nearly three-quarters in 2011, despite its success in Japan. Between late May and early June 2012, Lexus removed the HS 250h from its U.S. sales lineup, while a larger front-wheel drive hybrid sedan, the ES 300h, went on sale for the latter half of 2012.
According to Lexus, the HS designation stands for Harmonious Sedan.
Lexus displayed the HS 250h for the first time at the North American International Auto Show in 2009, with plans to launch the vehicle in major world markets including the U.S. and Japan. According to division officials, the HS was produced in response to consumer interest in dedicated hybrid models, with many stating that they would purchase such a vehicle if a luxury make offered one. The success of the Toyota Prius with upper-income buyers was also a consideration. The resulting HS 250h would become the most fuel-efficient in the Lexus lineup at its debut. At its launch, the HS 250h was also claimed to be the most fuel-efficient luxury vehicle in the U.S. The CT 200h, launched in 2011, later surpassed the HS 250h's fuel economy ratings.
To cater to environmentally conscious buyers, the HS 250h design included carbon footprint-reducing considerations, including the adoption of plant-derived "eco-plastic" (bioplastic) materials for the interior, cargo space, and foam injected areas. Bioplastic plant sources included kenaf fibers and castor seeds. Kenaf-based material was previously used in the Lexus ES rear interior. According to the manufacturer, 85 percent of the vehicle was fully recyclable. For the Japanese domestic market, the HS 250h featured a Harmonious Driving Navigator system which monitored efficient driving characteristics and compared them with others to determine the 'greenest' overall driver, for which charitable donations could be made.
The HS 250h's platform was based on the third-generation Toyota Avensis, itself related to the traditional gasoline engine Toyota Allion sold from 2001 to 2007, and was based on 2.4-litre-engined Corolla with electric motors. Other related models included the Toyota Premio, Toyota Vista (5th gen), Toyota Opa, Toyota Wish, and Toyota Caldina (3rd gen). In July 2009, the HS 250h made its sales launch in Japan, with 1,500 pre-orders logged at its introduction. This figure was reportedly three times greater than originally forecasted. The Toyota Sai, a sister model sharing the same platform and hybrid drivetrain, was launched in Japan in October 2009. However, HS 250h was not slated for the European market, where the similarly sized IS 220d and Toyota Avensis were sold.
The HS has a drag coefficient of Cd=0.27.
The gasoline-powered portion of the HS 250h powertrain is the 2.4L 2AZ-FXE inline-four engine. The 2AZ-FXE produces 147 horsepower (110 kW) and 105 foot-pounds force (142 N⋅m) of torque at 4,000 revolutions per minute. This is assisted by an electric motor for a combined output of 187 hp (139 kW) and 138 ft⋅lbf (187 N⋅m). The HS 250h uses a similar hybrid drivetrain as the Toyota Camry Hybrid.
