Lexus RX 2008 News

Toyota alone has plans for eight hybrids and they will be joined by everything up to super-luxury petrol-electric cars from Porsche and Mercedes-Benz. With a growing number of fuel-efficient diesel cars also landing from Europe, the number of bowser wowsers will soar as quickly as fuel economy falls. Toyota yesterday unveiled its third-generation Prius, the global hybrid poster car, with the promise of everything from 3.9 litre/100km fuel economy and CO2 emissions of 89 grams/kilometre to eco-plastics in the cabin and a solar roof panel to cool the cabin when the car is parked. But hybrids are still not cheap and parking a new Prius in the driveway will cost a minimum of $39,990. The Prius previews some of the technology to be seen next year in the company's first locally-made hybrid, a version of the Camry, and sets the benchmark for the upcoming Honda Insight. It will be the Prius's closest showroom challenger, although slightly smaller, with a pricetag set close to $30,000. Toyota Australia is aiming for 4500 Prius sales next year, in a global total which could go as high at 300,000 in 88 countries worldwide. "In future years hybrids will become the mainstream cars," the chief engineer of the new Prius, Akihiko Otsuka, said yesterday. The Prius push comes as a growing number of carmakers look for a fuel- efficient solution to the world's energy needs, as well as a segway to the all-electric cars which will eventually take over from petrol power. For Toyota, and its Lexus luxury brand, that will mean eight new models led by the Prius, local Camry and a compact Lexus called the HS250h. There is no talk yet of either a HiLux hybrid or any diesel- electric hybrid. "We have looked at diesel but it would be too expensive for the consumer," said Otsuka. The Prius has now been sold in Australia for eight years, although Honda was first into showrooms with its original Insight and still has the hybrid price leader with its Civic. But this is not as technologically advanced as the Prius. AUSTRALIA'S FAVOURITE HYBRIDS Toyota Prius Price: $39,990 Economy: 3.9L/100km Emissions: 89g/km Honda Civic Hybrid Price: $35,990 Economy: 4.6L/100km Emissions: 109g/100km Lexus RX450h Price: $89,900 Economy: 6.4L/100km Emissions: 150g/km

But that is no surprise with the heads of the Big Three carmakers all skipping the event to continue lobbying for a $US25 billion lifeline from congress in Washington.Ford still splashed with the official introduction of the 2010 Mustang, but Chrysler and General Motors both wound-back their involvement in the second-biggest car show in North America.That left the way clear for the imports, with Mazda pulling the cover off its all-new Mazda3 - the last car it will develop with Ford as its owner - Nissan revealing its revitalised 370Z and a new Cube, and Honda revealing a radical looking new concept coupe called the FC Sport.Lexus also has a new RX SUV, which is being simultaneously unveiled in Sydney and will come as both a pure petrol car and a hybrid, Hyundai is showing a Sonata hybrid concept and the plug-in Mini E electric car is making its first public appearance.The LA show usually draws a crowd of more than one million visitors but the attendance is expected to be well down this year with car sales off by more than 35 per cent in October and America's annual selling rate down by closer to 40 per cent.Still, cars like the Mustang will still draw a crowd in a city which is one of the most automobile driven in the world and there are plenty of pointers to the future including a growing number of electric cars led by the Mini but including concepts from Chrysler. 

It's hard sell, but Lexus thinks it can convince enough buyers to move into its new 400h. The 400h is the hybrid version of the RX350 and commands a $10,000 premium over the Sports Luxury petrol RX or a tick under $20,000 for the entry Sports RX. So the recommended retail of $94,100 is a fair sting for what is essentially a compact luxury SUV. Despite the cost drawbacks of wanting to go green Lexus says it has three months worth of orders and figures the 400h will account for about 20 per cent (1500 cars) of the RX volume in Australia next year. Since it first went on sale in the US in April last year 33,000 have been sold which accounts for 22 per cent of total RX sales. The 400h is based on the superseded 3.3-litre petrol engine which made way for the 3.5-litre RX350. Lexus says the new engine was unavailable for the world launch last year. The 400h joins Toyota's Prius and the Lexus GS450h sedan and Honda Civic hybrid as the list of petrol/electric vehicles grows in Australia. Next year Lexus will launch the world's first petrol/electric V8 hybrid, the LS600hL. So what are the benefits of having such an SUV wagon? Lower fuel consumption (8.1litres/100km), reasonable performance and vastly lower emissions (192grams/km) which on Lexus's figures is about 58 per cent of those of the nearest similar petrol engine. The hybrid incorporates three electric motors/generators while a compound planetary gear set in the transaxle acts as a power splitting device and electronically controlled continuously variable transmission to drive the front wheels. The front and rear main electric motors are used for normal starts and when more urge is required the third electric motor fires up the petrol engine which works in tandem with the other two electric motors. As in existing hybrid cars, the petrol engine switches off when the vehicle stops while the electric motors are ready for starts. Using the brakes makes the two main electric motors act as generators which help slow the vehicle down and send electric power to the battery. The Electronic Continously Variable Transmission is the essence of the hybrid which links the two 650-volt electric motor/generators and the petrol engine through the planetary gear set. Even the air-conditioning can be powered by electricity when the petrol engine is not functioning, as in stopping at traffic lights. The petrol V6 engine provides 155kW of power and 288Nm of torque while the main front electric motor generates 123kW and 333Nm. The rear electric motor is good for 50kW and 130Nm. The total system (petrol/electric) puts out 200kW with the petrol component driving the car and driving the third motor/generator to charge the battery. Lexus claim the 400h gives the luxury arm of Toyota a point of difference in the showroom. Already the Lexus GS450h powered by a mix of electric power and the 3.5-litre petrol engine is exceeding sales of the diesel BMW 530i and Jaguar S-Type turbo diesel. Lexus says the 400h has the advantage over diesels in that there is no mess at the bowser and there is no need for particulate filters. ON THE ROAD THERE are no compromises with the RX 400h something Lexus knows is vital to the market. Whereas there are compromises with diesel cars in terms of messy, smelly bowsers and soot filter replacement there is no such baggage with hybrids. About the only known hiccup is battery life. The 400h uses three electric motors and while there is no hard and fast evidence, Lexus says the life expectancy is more than 10 years. Lexus is unsure about battery life because it says it hasn't had to replace one. A replacement battery would be around $3000-$4000 but probably would be an issue for a used buyer. Inside the three-binnacle display remains except a power meter replace the tacho on the left. Surprisingly the 400h is a little soft on take off despite the factory claiming 7.6sec for 0-100km/h. There is not as much launch as one would anticipate particularly as take-off is powered by the electric motors which develop maximum torque at stall. And if you mash the accelerator everything starts to get a bit noisy, another surprise when Lexus is known for its refinement. On the drive in suburban Sydney and out to Camden in the south-west, the brake pedal felt a little soft and spongy, perhaps a result of the regenerative set-up of the stoppers. Once the 400h finds its legs and is up and running all is fine. The rolling performance is as good as any Lexus. The RX 400h shares a lot of kit with the RX 350 Sports Luxury version like 18-inch alloys, bluetooth, rear view camera and rear guide assist, touch-screen navigation and a fancy 11-speaker Mark Levinson sound system. What it gains over the RX 350 Sports Luxury is the VDiM (Vehicle Dynamics integrated Management System) which tells the rear electric motor to provide torque to the rear wheels to maintain stability, seat heaters up front, leather steering wheel instead of woodgrain and metallic trim on the shifter and surrounds as well as centre console. On the 70km launch drive with two up fuel consumption was 8.3-litres/100km from a best just below 8-litres to a touch over 8.5-litres. But fuel consumption is not the decisive factor in the buying decision. It is only a part of the picture, emissions and a machine which is seen to be a bit mean around town yet remains green is the essence of why people will ante up almost $100,000 for an electrified Lexus.
