Lexus IS300H News

The new IS upgrades are expected to help Lexus achieve a sales record in Australia of more than 9000 vehicles.

Lexus believes four-wheel steer could give it the edge over its competitors in the competitive sports sedan segment. The system has the rear wheels turn at the same time as the front ones -- but only a small amount -- to help the car through corners.The idea gained some traction with Japanese car makers in the 80s, notably with cars like the Honda Prelude and Mazda MX-6 coupe. At the time, it was touted as the next big thing but the system was clunky and could be expensive to repair if things went wrong.That was then this is now. Technology has moved on and BMW already offers the system with its 5 and 7 Series models and Lexus introduced four-wheel steer in the first of its cars last year with its GS line.It has also been trialling the system in the smaller IS range in Japan and the Australian arm of the company is keen to get a piece of that action. Lexus Australia boss Sean Hanley believes it could give the car a much-needed competitive edge.HOW IT WORKSLexus calls its system Dynamic Rear Steering (DRS), and has it turn the rear wheels of the car two per cent – a seemingly tiny amount but enough to make a difference to the cornering. At low speeds the rear wheels turn in the opposite direction to the front wheels to reduce the car's turning circle and the level of steering effort required.But at speeds of more than 80km/h, the rear wheels turn in the same direction as the front wheels. This makes the steering more responsiveness and gives it an intuitive feel at medium speeds, plus greater stability and vehicle posture for increased safety and comfort at higher speeds.The net result is the turning circle is reduced by almost half a metre at parking speeds and it also reduces the tendency of rear wheel drive vehicles like those produced by Lexus to step out or oversteer in a corner. We had the opportunity to put a car fitted with the rear wheel steer system through its paces on a recent trip to Japan. Unfortunately we had no car with standard steering to compare it with and Lexus has apparently not quantified the difference it makes to track times (although we thought that would have been an obvious thing to do). Having said that the car was plenty of fun to drive.WHEN MIGHT WE SEE IT HERE?Lexus wants to add the system to its F Sport models. "We think it gives us another progressive edge in the market place," Hanley says. "And the other thing is that it is significantly well developed now. So we're bringing to market a very credible technology, with great safety and performance that is aligned very very well to Lexus's innovative and fun to drive performance car strategy."At this stage the system is available only in Japan but it is under evaluation for other markets. If it is approved for overseas use it is likely to find its way into Aussie cars within the next year or so, probably when the car receives its mid-life facelift. Rear or four-wheel steer is part of the Lexus Dynamic handling System (LDHS) that features the world's first integration of Dynamic Rear Steering (DRS), Adaptive Variable Suspension (AVS), Variable Gear Ratio Steering (VGRS) and Electric Power Steering (EPS}.

Take some high-tech projection mapping software, an empty warehouse, an F1 driver and the new Lexus IS Hybrid and it becomes the recipe for the world's first full-sized, real time video game. Created for the Italian branch of Lexus, to launch the Hybrid IS there, the project chose 10 of the brand's Facebook fans and paired them with F1 driver Jarno Trulli and a projection mapping iPad app to compete against each other.Each had to design a race circuit, then ride shotgun with Trulli while tracing their course on the iPad, which projected their circuit onto the warehouse floor. Called 'Trace Your Road', the competition set the task of hitting seven designated touch points while completing the circuit in the fastest time.  Watch the 'Trace Your Road' video game action.  This reporter is on Twitter: @Karla_Pincott  

Lexus’ new IS range arrives in Australia next month, with all-new IS250 and IS350 models joined by the hybrid IS300h for the first time.Lexus has given Allan Jones an early taste of the new IS lineup around Sydney Motorsport Park, and his reaction suggests that Mercedes-Benz, Audi, and BMW are about to have a battle on their hands with their mid-size sedan models. 

Unveiled this week, the hybrid Lexus IS300h scores a big red tick in the Green Vehicle Guide with lowest CO2 emission of any luxury sedan including - the oiler averse brand is keen to point out - any diesel. Previously the Lexus IS range has been six cylinder petrol engines only and the two that power the outgoing range will be recycled for the new model. The 300h though is likely to be the highlight, producing 113 grams of CO2 per kilometre and using 4.9 litres of fuel per 100km on the combined cycle. The combined power output of 164kW from the Lexus IS300h petrol-electric drivetrain gets it to 100km/h from standing in a diesel rivalling 8.5 seconds. It's the first rear-wheel drive Lexus to have the Atkinson Cycle 2.5-litre petrol electric/hybrid powertrain, which features a D-4S fuel injection system, dual VVT-i and exhaust gas recirculation system. The engine drives the rear wheels through an electronic continuously variable transmission. The hybrid battery is positioned beneath the Lexus IS300h's luggage deck board which lowers the centre of gravity - a dynamic plus. From having a hopeless back seat and small boot, the new IS gets a 60:40 rear-fold seat. The Lexus IS300h will be available in Luxury and F-Sport grades, the latter with suspension tuning and electric power steering paired with adaptive variable suspension.  Both get the five setting drive mode select from more expensive Lexus lines. After driving a preproduction V6 through the Hollywood Hills late last year,  Paul Gover hailed the IS - being launched here in the third quarter - as having "pinched the 3Series' benchmark baton".  

It's hard to see what's happening under the camouflage, but Lexus is aiming for Audi-style quality and BMW-style driving dynamics with a car that's definitely going to be much more adventurous in design.
