  1. DOUG SODEN Manager, Product Planning LEXUS AUSTRALIA

  2. Rewrites performance / economy equation • First with electric AWD

  3. LEXUS Hybrid + E-Four = HIGH TORQUE

  4. Electric Power 50kW 123kW

  5. Electric Motor Torque 130Nm 333Nm

  6. 400 300 200 1000 4000 6000 Petrol Engine Torque (Nm) 160 288Nm Maximum 250Nm/1500rpm 120 Output (kW) 80 40 0 Engine Speed (rpm)

  7. High torque + 8.1L/100km =Diesel alternative LESS WEIGHT

  8. Diesel Competitors Weight 2040 kg 2105 kg 2150 kg 2235 kg 2350 kg RX400h X5 M-Class Touareg Discovery

  9. RX400h CO2Reduction per annum RX400h vs V6 competitor Reduction of 2 tonnes CO2 RX400h vs diesel competitor Reduction of 1.4 tonnes CO2

  10. 3MZ-FE Engine Valve timing change Smooth engine stop/start

  11. 400 300 200 1000 4000 6000 3MZ-FE Power & Torque Torque (Nm) 160 155kW@5600rpm 120 Output (kW) 80 288Nm@ 4400rpm 40 0 Engine Speed (rpm)

  12. No “fan” belt Changes of Hybrid Operation • Remove starter • Remove alternator • Add ceramic catalyst

  13. LEXUS Hybrid System Seamless acceleration Overseas model shown

  14. 2 x 650 Volt motor generators links to petrol engine, front axle via compound gear set

  15. Generator Battery Battery 2 x electric motors

  16. Solid-state Inverter 650V 288Vswitching

  17. GS450h Two-stage planetary gears

  18. Compound planetary gears x2

  19. 1 . 2478 drive motor gearing • multiplies torque, allows more compact motor

  20. Electronically controlled Continuously Variable Transmission • Optimum efficiency • No shift points • Seamless acceleration • No slippage / loss of energy

  21. E- FOUR • Saves on fuel • Traction when required • Added torque for take-off/acceleration • Traction in marginal conditions

  22. E- FOUR Operation • Acceleration • Tight cornering

  23. Regenerative Braking • RX400h – braking on both axles • Maximum efficiency

  24. E-FOUR / VDiM • VDiM can activate E-FOUR • Varies front / rear torque split • Up to 72 : 28

  25. VDiM Steering Assist Control Assistance is skid control, braking and accelerating on split – mµ surfaces

  26. Electric Power Steering • 42 Volt DC motor • Reduced engine load • 1.5% fuel saving • DC/DC converter

  27. RX400h Air-Conditioning • Electric-powered compressor • Cools vehicle while • engine stopped • Efficient cooling, greater • fuel efficiency

  28. RX400h NO COMPROMISE

  29. TRUE LEXUS

  30. ADVANCE ORDERS 12,500 LARGEST EVER RX400h USA Delivery: 33,000 (22% Total RX)

  31. RX400h Australia Projection: 2007 Hybrid = 20% Total Lexus Sales ADVANCE ORDERS 3 Months

  32. LEXUS HYBRID Australia Total Range Sports Luxury SUV / AWD V8 20% = 1500
