Lexus has unveiled the new GS F sports sedan at the 2015 Detroit motor show overnight.The GS F is Lexus’ third F-badged V8 performance car and the first to be based on the larger GS luxury sedan, which is otherwise only offered with V6 and hybrid powertrains.Featuring a much more aggressive stance than the standard GS models, the F sits lower and wider with flared wheel arches at both ends and completely redesigned front and rear bumpers.The front takes on Lexus’ big spindle grille with aggressive air intakes as well as redesigned slim headlights with signature tick-shaped daytime-running LEDs.At the rear the GS F features tweaked taillights, and a new rear diffuser housing quad stacked exhaust tips in typical F fashion.A large vent behind the front wheel has also been added along with a subtle carbon fibre rear lip spoiler and sportier side-skirts.On the inside, the GS F gains a sports steering wheel, digital configurable instrument cluster, sports seats and carbon fibre and Alcantara trimmings.Under the GS F's bonnet is the same 348kW/527Nm 5.0-litre V8 as the impending RC F coupe, with the same eight-speed torque converter automatic handling shifting duties.Three different transmission settings can be selected to give faster and more visceral gear shifts for spirited driving, or smooth changes for comfier cruising. Compared to its key rivals like the BMW M5 and Mercedes E63 AMG, the Lexus produces significantly less power than the 400kW plus Germans but at 1830kg is lighter thanks to its aluminium-intensive structure – though a 0-100km/h figure hasn't been revealed. Drive goes through the rear wheels via a torque vectoring differential – also borrowed from the RC F – that features three different modes including Standard, Slalom and Track. The latter two settings give the GS F improved stability and cornering agility over the default Standard setting. Compared to the standard GS sedan the F model features structural reinforcements, redesigned suspension and larger 19-inch wheels and tyres which cover bigger brakes with bright orange calipers.Tyres are 255/35 at the front with fat 275/35s in the rear provided by Michelin.The GS F is yet to be confirmed for Australia, but an early 2016 arrival is on the cards.

Driverless cars just around corner | Lexus

Everyone has heard the story about the tourist whose motorhome crashed after he set the cruise control and then strolled into the back to make a cuppa. It may be an urban myth, but technology marches on and you get the feeling the driverless car may be just around the corner, or certainly a lot closer than anyone thinks.This week Lexus demonstrated a further development of the active cruise control system fitted to its cars that steers and brakes the car without any need for intervention from the driver. It is still under development but Lexus hopes to bring the system to market within two years.THE SYSTEMDescribed as the next-generation advanced driving support system, Automated Highway Driving Assist (AHDA) links two automated driving technologies. At this stage its use is confined purely to the open road because city streets present too many variables such as pedestrians, motorcycles and in some cases an absence of line markings.DOES IT WORK?We received a first-hand demonstration of the system in Tokyo. Although we were not permitted to actually drive the Lexus GS fitted with the technology, neither in effect was the driver whose hands remained off the steering wheel, although they hovered close by.It works, and Lexus has data to show it does a better job of keeping the car on a straight course than your average driver. Spin-off effects include a reduction in traffic congestion as well as lower fuel bills.Curiously, the further back you are in a line of cars using the system, the greater the reduction in fuel consumption because of the 'drafting' effect (the reason cyclists ride in a peloton).In a column of four vehicles, consumption was down 5.3 per cent in the first vehicle, 17.7 per cent in the second and 26.8 per cent in the third - with an overall reduction of 11.1 per cent.Mind you the figures were derived over a period of four minutes and a distance of just a couple of kilometres.HOW IT WORKSThe system brings together Cooperative-adaptive Cruise Control, which wirelessly communicates with the vehicles in front to maintain a safe distance plus Lane Trace Control, which aids steering to keep the vehicle on course within the lane.Key to its success are a camera which monitors lane markings, together with GPS mapping of the route ahead and sensors in participating cars that enable them to talk to each other.In contrast to standard radar, Cooperative-adaptive Cruise Control uses 700-MHz band vehicle-to-vehicle ITS communications to transmit acceleration and deceleration data which allows vehicles following behind to adjust their speeds accordingly to better maintain their distance. Lane Trace Control draws on high-performance cameras, millimetre-wave radar and control software to enable an optimal and smooth driving line at all speeds. The system adjusts the vehicle’s steering angle, driving torque and braking force where necessary to maintain the optimal line within the lane. By reducing unnecessary acceleration and deceleration, the advanced driving system improves fuel efficiency and helps reduce traffic congestion.It's only a hop, skip and a jump from here to driverless cars, but the engineer who demonstrated the system to us said Lexus has no plans to introduce full automation.

Lexus GS is coming out of the closet

Overshadowed by the volume-selling IS sedan and larger, lavishly equipped LS sibling, Lexus is now focusing on the GS.A revised GS range has just been unveiled at the Detroit Motor Show and arrives here in time for the Melbourne Motor Show.The big changes are under the skin, though the car does get a mild cosmetic makeover.The big news is the flagship GS gets the same 4.6-litre V8 as the range-topping LS sedan. The GS460 develops 255kW at 6400 revs and 460Nm at 4100 revs. That's 47kW and 43Nm more than the 4.3-litre GS430, which it replaces.The GS300 and GS450h carry over.Lexus Australia chief executive John Roca says the power gains bring the range-topper in line with the performance of the GS450h.However, compared with the LS460, power and torque are down in the GS460 because it misses out on the LS's direct-injection system.The V8 does share its eight-speed automatic transmission with the LS, which is lighter and more compact in the GS than the six-speed automatic it replaces.Despite the reduced power, the 4.6-litre in the GS is no slouch, hitting 100km/h in 5.8 seconds and reaching a top speed of 240km/h.Roca says apart from improved engines, the sedan gets some small visual tweaks.On the outside there is a chrome grille surround, new integrated indicators in the door mirrors and new alloys.Both bumpers have been restyled.The GS 450h gains several styling cues from other Lexus hybrids, relating to badging and hybrid blue highlights.Inside, audio and telephone controls on the steering wheel have been revised and the boot and fuel filler releases have been moved outside the drop-down switch module.All models now have an input jack for portable music players.For added security, the doors have an automatic locking function triggered when the vehicle is on the move.Roca says GS sales stalled last year, in part because the car was in run out mode.“We will refocus on improving the GS's share this year,” he says.GS sales were down 21 per cent last year, compared with 2006, while overall Lexus sales were up 14.5 per cent.The IS250 remains the best seller in the range, accounting for about half of sales.GS pricing is expected to be decided next month.Roca hopes to hold prices at current levels. That means the entry GS300 Sports should stay close to $95,000 and the new 4.6-litre V8 GS460 about $138,000.

Lexus GS450h practically drives itself

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.

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."

A greener Commodore coming

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.

Green machines for clean motoring

Ten years.The average life expectancy of a Hybrid car. The average number of years it would take to break even in fuel savings after investing in a premium diesel engine.And the average number of years that some industry experts expect the current crop of petrol engines with manual transmissions to last before emissions standards render them useless.A sobering statistic, yes, but for years manufacturers have been working around the problem of emissions, pollutants, and waste to produce not only a cleaner, eco-friendly car, but one that does not compromise on performance, luxury or price.Though you would not know that this was the future of motoring from the empty green stands at this year’s show.The place to show off the future tech is, as always, the motor show stand, and this year saw an absence of previous shows’ futuristic displays of alternative fuels.However, there were some exciting models that are not simply concept, but close to, or in, production.Saab brought out its BioPower models, which are specifically designed to run up to 90 per cent ethanol - though the car can run on petrol if an ethanol pump cannot be found.Saab claims the use of ethanol as an environmentally friendly renewable fuel source with low emissions. And the green goodness produced by the crops such as sugar cane from which ethanol is produced can statistically counteract the resulting emissions from both the manufacturing process and the cars that use the fuel.Ethanol’s premium over petrol at the bowser is also supposedly negligible.While BioPower production cars were on display, the show is stolen by the Aero X concept that floored the floor at Geneva.Running a 2.8-litre, twin-turbocharged V6 engine and with a jet-fighter inspired design and cutaway cockpit (even the wheels look like propellors), the 100 per cent ethanol green machine claims no carbon emmissions while producing a supposed 4.9 second 0-100km/h sprint time (it is yet to be taken to a drag strip for official performance testing). Ethanol and performance?Theoretically, no problem…But the biggest selling production alternative is still the petrol-electric hybrid.Honda’s Civic Hybrid and Toyota’s Prius models have the market almost exclusively to themselves, but the luxury genre has entered the greenhouse with Lexus.Toyota has lent its technology to sister company Lexus this year with the GS450h, and more recently, the big RX400h SUV which sits atop the Lexus stand.This uses the combination of front and rear electric motors with a 3.3-litre V6 petrol engine to power the car.When accelerating, the systems work together to give the car a combined 200kW, and capturing the energy usually wasted during deceleration and braking to recharge the electric motor. So no cords or power points necessary.There is a catch - the estimated life of the battery in this type of hybrid is estimated at ten years.As no hybrid has been around that long (the Prius first hit the market in 1997), and Toyota has never replaced a hybrid’s battery as yet, we will have to wait until 2007to see whether we have power, Y2K, or the start of expensive battery replacements.And it will be in 2007that we slap eyes on Lexus’ (and the worlds’) first hybrid V8; the AWD LS600hL limo version of the petrol LS460 seen at this year’s show.Not to be outdone, BMW is scheduling a hydrogen duel-fuel V8 for 2008, which combines the company’s stalwart 4.4-litre petrol engine with liquid hydrogen fuel cells.It is being kept under wraps for the moment, and the fact that hydrogen would cost over $4 a litre here does not make for a clean start in Oz.But while some of this cool tech was never going to make it to Sydney, the anticipated concept-come-production-car, the Peugeot 307CC Hybride diesel, was due to be revealed – and wasn’t. Reliable technology? Hmmm.The 307CC Hybride is a cool concept. The combination of a diesel engine with an electric motor in the cool convertible produces a teeny fuel consumption figure of just 3.7L/100km.Unfortunately, like so many of the fantastic fuel alternative ideas and ideals, the tech is too expensive at present to make a production car viable, and its release is scheduled for 2010.Not to mention the fact that it missed the plane to Sydney from the Paris show, and we had to settle for the new 207 and a half-naked woman on the stand instead (yes, we are mentioning her again – but that particular model was a literal show-stopper).One thing is for sure: environmental concerns are weighing heavy on all car maker's strategic decisions for new models. But at this stage most are still not revealing their long term plans to deal with emissions and fuel efficiency.Who knows what kind of alternative fuels and cars will be on the market in ten years time? And will the old Prius be running, or running out of battery?Either way, it won’t be long before we are all driving with a smug, earth-saving smile of some sort on our faces.Hopefully, the future of green motoring will be cars like the Aero X…

One of the headline acts will be the French star of recent independent crash tests - the Citroen C6 - which has been acclaimed as the safest car yet tested by the New Car Assessment program.The C6, set to go on sale in Australia by the middle of the year, is the fi rst car to earn the maximum four stars from Euro NCAP for its pedestrian safety rating, as well as a maximum fi ve stars for occupant protection.It's also won an award as the world's most beautiful large sedan.The C6 is offering two V6 engines - a 2.7-litre 150kW turbo diesel or a three-litre 155kW petrol engine; both drive the front wheels via a six-speed automatic gearbox.Alfa Romeo's 156 range brought the Italian brand back to the fore in Australia with fl air and passion. It's replacement, the 159, continues in that tradition. It will offer more modern drivetrains - and even a V6 with Australian roots - when it hits the market mid year.Designed by Giorgetto Giugiaro and the Alfa Romeo Styling Centre, the new car will come in both front and all-wheel drive versions, with the Q4 permanent four-wheel drive system using three diffs to split drive.The Alfa Romeo 159 is the first of a whole family of new Alfas due over the next two years, including the Brera.Lexus will be the fi rst car maker to offer a luxury hybrid model, with its GS petrol-electric hybrid offering plenty of performance with the thirst and emissions of a two-litre.The Toyota-owned luxury brand also has a hybrid version of the RX SUV but the company's stand in Adelaide will feature the RX350 - which sees the looks get a nip and tuck, with a new more-powerful and more fuel-effi cient engine beneath its sculpted snout.When Volkswagen went back to the factoryowned subsidiary, they announced high hopes of surpassing 20,000 units by now. They haven't got there yet but with more than 15,000 sales last year the German car maker is on the right track.The prestige segment will see the Passat return with a vengeance this year, with direct-injection two-litre petrol and turbo-diesel engines, or a V6 petrol engine, on offer in either sedan or wagon body style.The sales have had a boost from the new Golf and the newly-introduced (and keenly-priced) Jetta, giving the German car maker plenty of ammunition to work with.Peugeot will give Adelaide show-goers a look at its new 407 Coupe, a sleek, powerful and attractive 2+2 that will be offered in petrol and diesel models on sale in Australia as the show opens.The coupe will be offered with a three-litre 155kW/290Nm V6 petrol engine with either a sixspeed manual gearbox or new six-speed automatic transmission for $65,990 and $68,190 respectively.The sleek Pug will also be offered with a 2.7-litre V6 HDi twin-turbo diesel offering 150Kw and 440Nm with a six-speed automatic gearbox as standard. It will be priced at $72,500.Porsche chose to introduce the Australian motoring media to the Cayman S in the countryside surrounding Adelaide and its fi tting the German brand returns to the motor show this year with the same model.The Cayman S is more than a Boxster with a roof, sharing inlet systems and some other nice bits with the 911.The bulk of the DNA traces back to the midengined Boxster, which gives the two-seater Cayman the same basic powerplant - although slightly larger - plus the superb road manners and balance that has made the convertible a popular option among Porsche buyers.Chrysler has returned to the Australian market with plenty of enthusiasm and some interesting product, the latest and most powerful example of that statement being the 300C sedan.Soon to be followed by diesel and wagon variants, the V8 300C has serious visual impact and packs plenty of equipment to take on the big locally-built luxury sedans.The Chrysler has the added attraction of displacement on demand, which drops fourcylinders from use to save fuel when light throttle loads are required.
