Lexus GS350 News

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. 

A member of the 2013 Australia's Best Cars judging panel says motorists are spoilt for choice right now. Royal Automobile Club of Tasmania general manager of roadside and technical Darren Moody -- who sits on the panel with judges from motorist clubs around Australia -- says new car buyers have access to record low interest rates and are still getting great value for money, despite a recent dip in the value of the Australian dollar.He and the 11 other judges from around the country had been trying to make life even easier for buyers, testing 50 vehicles in 15 categories for the 2013 best car awards.The awards, run by the Australian Automobile Association, involved all the state auto clubs. In October Mr Moody and the other judges spent six days at the Australian Automobile Research Centre at Anglesea in Victoria testing all the vehicles.The judges' choice this year was the Mazda6 Touring, winner of the category for best medium car under $50,000. "It brings premium features to the category," Mr Moody said. There was no winner in the people mover category this year. AAA chief executive Andrew McKellar said it was the first time in the 13 years of the program that an award has been withheld."It's unfortunate that not one vehicle in that class meets the expectations of an Australia's Best Car," he said.Australia's Best Cars 2013Judges' choice: Mazda6 TouringBest light car: Renault Clio Expression TCe 120Best small car under $35,000: Hyundai i30 ActiveBest small car over $35,000: Audi A3 Sportback TFSI CoDBest medium car under $50,000: Mazda6 TouringBest medium car over $50,000: BMW 320iBest large car under $60,000: Holden Commodore VF SV6Best large car over $60,000: Lexus GS350 F SportBest people mover: Award withheldBest sports car under $50,000: Volkswagen Golf GTIBest sports car $50,000-$100,000: BMW M135iBest SUV under $45,000: Subaru Forester 2.5iBest SUV $45,000-$65,000: Hyundai Santa Fe Highlander CRDiBest Luxury SUV over $65,000: Volkswagen Touareg V6 TDIBest all-terrain 4WD under $100,000: Land Rover Discovery 4 TDV6Best 4x4 Dual Cab Ute: Ford Ranger XLRead the full story here. 

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.

The safety recall is to fix electrical and mechanical defects that could cause the vehicles to either stall while being driven, or to go into 'limp home' mode, where they can be driven only at designated lower speeds.The 2006-2008 Lexus RX 400h is being recalled for a problem in the car's hybrid system that could see solder on transistors become heat damaged -- particularly under high load or when towing -- activating warning lights and shutting down the system, causing the vehicle to either go into 'limp home' mode or shut down altogether. The Australian portion of the recall will affect about 1750 Lexus RX400h vehicles built from June 2006 to December 2008. Lexus said there had been no incidents related to the issue reported in Australia, but cautioned care while driving. "Motorists can continue to drive their vehicle, however are advised to avoid towing, or rapid acceleration until the vehicle has been inspected," Lexus spokesperson Beck Angel said. "Motorists are advised to stop driving and contact their preferred Lexus dealer if the engine warning lights illuminate."More than 100,000 Lexus IS 350, IS 350C and GS 350 vehicles from 2006-2011 are also being recalled for a defect in which bolts securing the variable valve timing control device may work loose, causing the vehicle to stop. Lexus has alerted owners that an abnormal noise in the vehicles may show early symptoms of the defect. Affected customers will be notified of the recall by mail at their last known address and asked to make an appointment at their preferred Lexus dealer, where affected parts will be replaced. For further information about the recall, customers can call the Lexus Customer Assistance Centre on 1800 023 009.

...even hot-lapping the mid-sized luxury contender at the Nurburgring.Carsguide knows the Lexus GS is a lot sharper after a drive in the US and is waiting for the disguise to be stripped away so we can see how close the car is to the Lexus LF-Gh.

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.
