Toyota European Sustainability Report 2010 I Environmental Performance 52 Andy Pfeiffenberger Vice-President, Lexus, Toyota Motor Europe Full hybrid technology Now in its second generation, Lexus Hybrid Drive combines electric motors and a petrol engine into a sophisticated power source that reduces emissions, boosts fuel economy and offers refined performance. Lexus Hybrid Drive meets customers’ demands for lower CO 2 emissions as well as their preference for performance. The demand for improved environmental performance continues to increase. The concept of full hybrid technology has substantial development potential compared with conventional powertrains. The new RX 450h, the first vehicle to use second-generation Lexus Hybrid Drive, demonstrates the advances that are already being made. Compared to the previous model, it benefits from a 10% improvement in power output and a 23% reduction in CO 2 emissions. In 2010, the CT 200h will go on sale, reinforcing Lexus’ commitment to making full hybrid technology available to a wider section of the European customer base. The CT 200h will have category leading environmental performance. Its CO 2 emission levels will be the lowest in the segment and particulate matter and nitrogen oxide emission levels will be significantly lower than diesel engines. The CT 200h will contribute to the acceleration of the mix of full hybrid technology within Lexus’ overall European sales. Currently, approximately 50% of all Lexus’ sold in Europe are equipped with Lexus Hybrid Drive. The launch of CT 200h will see this proportion increase to around 75%. The aim is to have 100% of all Lexus’ sold in Europe equipped with Lexus Hybrid Drive by 2013. In addition, Lexus Hybrid Drive uses a flexible platform, which Lexus “ Lexus has pioneered key technologies that offer a premium driving experience with category leading environmental performance. In particular, Lexus is building on its leading knowledge and experience with full hybrid technology to increase the proportion of cars sold with ‘Lexus Hybrid Drive’, which provides a refined and rewarding drive with category-leading environmental results. „ Andy Pfeiffenberger can be further developed as new technology becomes more feasible. For example, hybrid technology works together with a whole range of current and advanced fuels, from advanced biofuels to hydrogen. CT 200h RX 450h

By re-examining the whole structure of the internal combustion engine, Lexus has developed technologies like Electronic Variable Valve Timing with Intelligence, which raises the efficiency of the combustion process meaning less fuel is used and D-4S, which features both direct and port injection, improving performance and efficiency across the power band.

Lexus is pioneering the use of materials with high recoverability, and researching and utilising parts that are easy to reuse at the end of their life. For example, bumpers are recycled to make trim for the luggage compartment and shredded sound proofing material is used for the silencer behind the dashboard. Car door trims are now made with the stem of kenaf, a member of the hibiscus family, rather than the woodchips previously used. Kenaf absorbs between two and five times as much CO 2 as other plants and is mixed with old waste bumpers from car repair shops to make door trim that is lighter, has better sound-proofing, and uses material that does not deplete forests. 100 80 60 40 20 0 CO2 and NO x Lexus RX 450h versus competitors -16% -16% -3% -4% -5% A B A B A B A B A B CO2 NOx NMHC PM SOx Material Production Driving/Maintenance A RX 400h Vehicle/Parts Production Recycling B RX 450h 1 0.8 0.6 0.4 0.2 0 Toyota European Sustainability Report 2010 I Environmental Performance 53
