2009/2010 Lexus HS250h unveiled by Toyota as first hybrid-only Lexus model

channelnewsasia.com :

Toyota unveiled on Tuesday [14 Jul 2009] its first Lexus sedan available only as a hybrid, hoping that the popularity of fuel-efficient vehicles will help the luxury range buck the economic downturn. The 2009/2010 Toyota Lexus HS250h sedan offered improved fuel efficiency of 23 km/l [43 mpg], combining a 2.4L petrol engine with an electric motor. The Lexus line already has several hybrids, but the HS250h is the first hybrid-only model.

The new Lexus will go on sale in North America in September. Japanese automakers have made strides with hybrid cars because of high oil prices and growing concern about emissions blamed for global warming. The 2009/2010 Toyota Prius has been the top-selling car in Japan for the past two months. Rival automakers are seeking to challenge its lead. The 2009/2010 Honda Insight hybrid was the top-selling car in April, before being overtaken by the Prius.

- Still early days yet to see how this particular model will do, but it's good to Toyota continue to execute on its all-hybrid model strategy. By puting its Hybrid Synergy Drive (HSD) system on different models and with increased production, Toyota would gain valuable integration experience as well as achieve economies of scale, so as to be able to drive down the cost of the hybrid components for future model generations.
