Lexus GS 2007 News

Picture this. You're driving along the motorway. The Lexus you are travelling in purrs, whisper quiet. It looks good, too, good enough to draw admiring glances. Up ahead the storm clouds gather and it is not long before the first drops of rain spot the windscreen. The wipers come on automatically. The kilometres rush by and as darkness begins to fall, the car's xenon lights flick on automatically, dipping briefly before coming to rest. There's still a long way to go, but not wanting to get a speeding ticket, you wisely decide to engage cruise control. A digital readout tells you the car's speed is locked to 110km/h and that's where it will stay, unless you are forced to brake for a slow moving vehicle. You have programmed your destination into the car's on-board satellite navigation system, so there's no need to worry about when to turn off or, for that matter, finding the street the 'satnav' will tell you. Ahead a car decides it has had enough of life in the slow lane and suddenly moves out into the lane ahead. Before you have time to react the car does it for you, slowing to match the speed of the vehicle ahead. A couple of minutes later the vehicle returns to the left hand lane and your car's speed climbs automatically back to 110km/h. It's called active cruise control and it is made possible by the in-built radar that scans the road ahead and reacts if any objects move into its path. To while away the hours you turn on the 5.1 Mark Levinson sound system. It's got 14" speakers and sounds better than the hi-fi set up in the lounge room at home. Although the “rels” live almost 800km away, you will probably make it on one tank of fuel. That's because this car is an energy-efficient hybrid and runs on a combination of petrol and electricity, storing the energy normally lost during braking. But it's not like any hybrid that you have driven before, because this car really gets up and goes, with a combined output of 254kW. The drive train consists of a 3.5-litre V6 and a 650-volt electric motor. The latter produces 147kW alone. Power is delivered to the rear wheels through a state-of-the-art continuously variable automatic transmission that doubles as a six-speed manual. The dash from 0-100km/h takes 5.9 seconds and it uses just 7.9 litres/100km. If your route takes you over dirt roads, you can switch from sport to comfort setting using the electronically modulated suspension system. In the unlikely event of an accident, the car is fitted with pre-collision lock down system along with 10 airbags. Parking is a snack too, with front and rear distance sensors and a rear view camera. It doesn't get much better than the Lexus GS450h. It's a wonder the car isn't able to park itself. But then Lexus's flagship LS 600hL can lay claim to that feat. The GS450h is priced from $124,900 and Lexus has just released an updated model.

The NRMA Insurance reversing visibility index shows 12 vehicles, including the Toyota Corolla and Holden Commodore, fail to receive any stars in testing.The test, established because of the deaths of 17 children killed by reversing cars in driveways, measures how well a driver can see out of the back of the vehicle.Of the 12 vehicles with a zero rating, five fit into the small-to-medium segment.The result has prompted the NRMA to call on manufacturers to consider installing reversing camera technology in all cars, not just bigger vehicles.“Without a camera, blind space can range from 3m to 15m,” NRMA Insurance road safety manager Pam Leicester said.“That's a large range for children to be hidden from a driver's view.” With an average of one child run over in their own driveway every week, Ms Leicester said it was time to start focusing on improving visibility in all models.“There has been a focus on four-wheel-drives and reversing but as our results show, that's an issue for all types of vehicles right down to small cars,” Ms Leicester said.“This is a real concern because many of these vehicles have hazardous reversing blind areas, usually caused by high rear window lines and boots.”Vehicles that received a zero rating included the Holden Commodore (Epica and Viva), the Hyundai i30, Mitsubishi's Lancer and 380, Toyota's Corolla, Prado and RAV4, the Honda Civic and the Odyssey, as well as the Hummer H3.Overall, however, the results have improved from last year with more manufacturers adopting reversing cameras.This is especially the case in the four-wheel-drive and luxury segments. Only five vehicles offered reversing cameras either standard or as an option last year.The technology was available on 15 vehicles this year. They gained either a 4 1/2 or 5-star rating.Ms Leicester said they were particularly impressed with the new Toyota Kluger, which has a reversing camera as standard on all models.The top performers given a five-star rating were the BMW X5, Ford Territory, Honda Legend, Lexus GS430, IS250 and LS460, and the Toyota Kluger; all offering a camera as standard or as an option.“We encourage all manufacturers to start thinking about putting reverse cameras in their vehicles,” Ms Leicester said.“At the time of manufacture, it's a very small cost.”Ms Leicester said after-market reversing cameras also could improve visibility and were available for between $200 and $300. How they rated NRMA insurance reversing visibility indexBest: BMW x5, Ford Territory, Honda, Legend, Lexus GS430, Lexus IS250, Lexus LS460, Toyota KlugerWorst: Holden Commodore, Honda Civic, Honda Odyssey, Hyundai i30, Mitsubishi Lancer, Toyota Prado, Toyota Corolla 

Toyota Australia is planning to build a hybrid version of its family-sized Camry or Aurion and have it on sale within four years.Toyota's head of sales and marketing, Dave Buttner says one will get the hybrid petrol-battery system.Toyota sells three imported hybrids, the Prius, based on the Corolla; a Lexus prestige sedan, the GS450h; and all-wheel-drive wagon, the RX400h, while a V8 luxury saloon, the LS600hl is due later this year.The home-grown hybrid would be built on the same lines as the Camry and Aurion at Toyota's Altona plant.“We want to be the first local manufacturer with green credentials. We want to be known as the company that was first to market,” Buttner says. “We want to be the leader on this issue. We have been looking at the Camry and Aurion for the hybrid and it's looking like the Aurion. It will go on sale in 2011 or 2012.”Toyota has been encouraged by the take-up rate of its hybrid Prius.“When launched, 3 per cent of sales went to private buyers, now it's 39 per cent,” Buttner says."Demand for our Lexus hybrids is double (our) expectations."  

Experts say hybrid-engine technology could be available in the Holden Commodore sooner than we think. Recent important developments include:- General Motors in the US announcing it has put a hold on future rear-wheel-drive planning while moving ahead with development of hybrid and electric strategies for its global brands that include GM Holden;- GM Holden confirming it is working on a diesel option for Commodore;- A leading manufacturing expert warning Australian carmakers at a key conference this week they need to expand their focus to smaller and greener cars to survive;- Most overseas car companies expanding their development into alternate-powered cars;- The European Commission unveiling a strategy to make car companies cut carbon dioxide emissions in all new vehicles by 2012, and;- The US Supreme Court ruling that carbon dioxide emissions from cars are subject to the same tough standards as other emissions.GM vice-chairman Bob Lutz says the company is putting a hold on rear-wheel drive projects. “We've pushed the pause button. It's no longer full-speed ahead,” he says.Two of the most important RWD cars in the works are the Chevy Camaro sports coupe, due back late in 2008, and the full-size, RWD replacement for the Chevy Impala sedan for 2009. Both are expected to be huge sellers in the US and contribute profits to GM, which is still burdened by financial woes.“It's too late to stop Camaro, but anything after that is questionable or on the bubble,” Lutz says.The RWD cars will be larger and heavier than front-wheel-drive cars so it comes down to the matter of fuel economy. Or, as Lutz says: “We don't know how to get 30 per cent better mileage (from RWD cars).”That 30 per cent bogey arises from a proposal by the US Government to raise corporate average fuel economy standards by 4 per cent a year so cars will have to average 34mpg (6.9L/100km) by 2017, up from 27.5mpg (8.5L/100km) today. On top of that, the Supreme Court ruled last week that the Environmental Protection Agency can regulate carbon dioxide expelled by cars, a gas that contributes to global warming. The EPA doesn't do so now.GM Holden boss Denny Mooney has confirmed development for a possible diesel option for Commodore but denies a bespoke hybrid development for Holden.Following reports this week that Holden engineers were working on a hybrid system, the company says the development engineering is a GM global program based in North America, driven by a joint venture with DaimlerChrysler and BMW.“We're (GM) doing engineering work on a two-mode hybrid,” Mooney says. “It's our joint venture with DaimlerChrysler and BMW.”Mooney says the expense of hybrid development puts it outside the capacity of individual brands within GM but a global GM hybrid or electric strategy could flow to Australia.Holden has dabbled in hybrid and electric technology with the ECOmmodore which highlighted the use of supercapacitors and lead acid batteries. The work, a joint venture with the CSIRO, centred mainly on maximising stored electric power.In Melbourne this week a leading manufacturing expert and director of the US Centre for Automotive Research, Jay Baron, urged local makers to embrace change.He told the Society of Automotive Engineers conference any failure to reflect the needs of a rapidly changing global market was risky.Although supportive of Australia's carmaking business and its export efforts of both cars and intellectual property, he believes hybrids and smaller cars represent the new growth areas for the next 10 years.Baron was also surprised Australia, with a market of less than one million new cars a year, could sustain four major car manufacturers.“A state-of-the-art high-volume manufacturing plant today has to produce somewhere over 200,000 cars a year,” he says.Locally, Ford, GM Holden, Toyota and Mitsubishi are well under this figure. “If you're not producing that volume, then you are a scaled-down niche plant and being in a niche market right now is risky,” he says.“Rear-wheel drive cars are slowly becoming niche markets. In Australia the question is: Are there enough niche markets out there so that you can supply the world with rear-wheel drive cars?“It's a little bit of a risky future not to be looking at where the growth is and the growth is small, efficient cars and new technologies.“There is a whole family of hybrids coming out that could totally change the market again as they slowly scale up.”The change in car buying values and habits is part of a broader cultural shift in the industry.“In North America we're moving away from sports utility vehicles to CUVs — crossover utility vehicles — and higher mileage vehicles,” he says. “In Australia you're transitioning from rear-wheel drive to small front-wheel drive cars, which tend to be more imported.“So you're experiencing similar problems to those we're having.”Baron was the keynote speaker at the conference, which also featured Holden's executive director of engineering, Tony Hyde, Toyota's vice-president of the Toyota Technical Centre in Melbourne, Max Gillard, and the design director of Ford Asia-Pacific, Scott Strong.Toyota spokesman, David Buttner says the company has no plans to produce smaller cars in Australia, but the development of future hybrids is an important factor for the company, “We are continuously evaluating the opportunities to introduce hybrids into Australia, we are working with all stakeholders including the government to facilitate this development,” he says.Ford spokeswoman, Sinead McAlary says the company is constantly examining ways to improve all aspects, such as fuel economy, but a complete shift in focus may not be possible.“To say the Australian industry should develop small cars or hybrids is not necessarily very practical,” she says. “The Australian market is also not ready for the Australian car industry to be producing hybrids.”McAlary says hybrids only accounted for around 3000 sales last year, which is less than the number of Falcons that Ford produces in one month.She says the technology is expensive and people have to be prepared to buy the vehicles, before manufacturers can change the way they operate. “The market has to be ready for it,” she says.And while car companies feed into the new technology that's already being developed in the US and Europe, McAlary says “our industry is too small for us to develop it by ourselves”.Toyota with the Prius, Honda with the Civic and Lexus with the RX440h and GS450h are the only three companies selling hybrids in Australia, but many manufacturers have displayed concept vehicles.One of the newest overseas manufacturers to create a hybrid is Proton, in collaboration with Lotus. Unveiled at the Geneva motor show, the Proton Gen.2 EVE hybrid concept has a claimed fuel economy figure of just 5.6L/100km — some 28 per cent better than the petrol road-going version. Proton has not revealed whether it is planning to mass-produce the hybrid.
