LA Auto Show Preview: 2010 Lexus GX 460

Lexus has revealed the second-generation of its GX midsized luxury SUV, the GX 460, ahead of its official debut next week at the LA Auto Show. The same size as the model it replaces, the new GX 460 is still an old-fashioned, body-on-frame design that shares a platform with the redesigned Toyota 4Runner. Both are traditionally capable off-roaders. But it promises more refinement, through technology and conveniences. For example, a power-folding third-row seat folds flat into the floor, rather than up against the sides as the old one did. And that is just the beginning.

The name change also represents moving to a new 4.6-liter V8, which makes 301 hp, up from 263. The standard transmission is a new six-speed automatic–upgraded from last year’s five-speed. EPA fuel economy estimates are 15 mpg city and 20 highway, for a combined 17 mpg; the last GX returned 15 mpg combined.

A host of new high-tech features provide protective systems for everything from off-road driving to on-road crash performance.

Previously optional, the new Kinetic Dynamic Suspension System (KDSS) is now standard. It hydraulically controls the anti-roll bars for reduced body lean in corners, and disengages the bars for greater off-road articulation. The vehicle also has downhill assist control to automatically limit descent speeds on steep slippery grades off-road. The Crawl Control, trickled down from the Land Cruiser, is a feature that automatically controls the throttle to maintain a set speed on slow off-road ascents. Crawl Control engages automatically when low-range is selected and the crawl speed can be adjusted manually. Hill start assist keeps the vehicle from rolling back when starting on an uphill.

All-new 2010 Lexus GX 460

Things are a little rocky for Toyota of late, prompting among other things company president Akio Toyoda to announce plans to review and possibly trim the line-up of full-frame trucks. Meanwhile, Lexus has just revealed the next generation of its "midsize" sport-utility vehicle: The all-new 2010 Lexus GX460--named for the displacement of its V-8 engine--replaces the GX470 with an all-new engine, both more efficient and more powerful than the 4.7-liter it replaces--while keeping the stout body-on-frame construction.

Although the 4.6-liter V-8 produces 301 horsepower and 329 lb-ft of torque, the Lexus GX460 is about more than just power. There's also standard seven-passenger capacity and full-time four-wheel drive, and the GX460 has active suspension that changes the degree of roll stiffness with an adjustable anti-roll bar. Lexus says the system, which it calls Kinetic Dynamic Suspension System, or KDSS, can reduce lean in corners by up to fifty percent while still maintaining the suspension flexibility needed for off road use. Stability control, brake assist and electronic brake-force distribution are all standard as well.

The Specs

How closely related is the GX 460 to the new 4Runner? Well, they both ride on the same 109.8-inch wheelbase and the slight differences in other specifications can be attributed to slight differences in bumper, roof rack and wheel design. The outgoing GX 470 rode on a 109.8-inch wheelbase too. This is not the case of a vehicle growing larger.

However, it is a vehicle that's gotten heavier. According to Lexus, the 2009 GX 470 weighed in at a full-figured 4871 pounds while the base 2010 GX 460 is an obese 5305 pounds. That's a 434-pound increase.

Fortunately, the GX 460 is blessed with a stout heart. The GX 470's iron-block "2UZ-FE" 4.7-liter DOHC V8 has been replaced by the new, all-aluminum "1UR-FE" 4.6-liter V8 DOHC V8 (which is not, incidentally, the same 4.6-liter V8 installed in Lexus cars). Featuring continuous variable valve timing and a thirst for 91-octane or better fuel (but not utilizing direct injection), the new engine is rated at 301 hp at 5500 rpm and 329 lb-ft of peak torque at 3500 rpm. That's a substantial improvement over the outgoing motor's 263-hp at 5400 rpm, but only a modest bump up from the old engine's 323 lb-ft of peak torque at 3400 rpm.

Strangely though, the GX 460's engine lags 9 hp behind the essentially identical 4.6-liter V8 installed in the 2010 Toyota Tundra pickup, and the Tundra engine is rated to operate on 87-octane fuel. Intake and exhaust-system differences are the likely power thieves here.

The sole transmission behind that new engine is the same six-speed automatic used in the Tundra equipped with the 4.6-liter V8 and a step up from the five-speed used in the GX 470. It shifts so smoothly that its operation is effectively undetectable. The full-time all-wheel drive system has an electronically controlled two-speed transfer case and a locking center differential. The standard 265/60R18 mud-and-snow tires aren't particularly aggressive by off-road standards, but the drivetrain makes every effort to help them gain traction.

Considering the amount of heft the GX 460's engine must lug, that it achieves an EPA-estimated 15 mpg in the city and 20 mpg on the highway is surprising, if not impressive. And the GX 460 is rated to tow up to 6500 pounds when equipped with the correct hitch.

The suspension uses double A-arms in front with a solid axle on coil springs located by four links in back—hardly exotic stuff. But it's complemented by a four-wheel Adaptive Variable Suspension (AVS) system and, on the rear wheels, Adjustable Height Control (AHC). Those both seem to work well enough, but the star here is the same Kinetic Dynamic Suspension System (KDSS) used on the off-road ready Trail version of the 4Runner.

The KDSS system manages the connection of the stabilizer bars to the GX 460 through the use of electronically controlled hydraulic cylinders at the points where the bars would otherwise conventionally mount to the frame. Extending the hydraulics has virtually the same effect as disconnecting the stabilizer bars and increasing suspension travel when the going gets hairy.

So that's the substance and steak of the GX 460. The sizzle comes in the details.

For some, there might be too much technology crammed into the GX 460. The dashboard, center stack and steering wheel are an absolute riot of buttons, with knobs and sliding panels that hide more buttons and knobs. Of course there's a navigation system, redundant audio controls, switches for scrolling through information displays, more switches that tell the all-wheel-drive system what to do, and, optional in Premium-grade models, a package that bundles a driver monitor, lane-departure alert system, "intelligent" high-beam headlamps and a dynamic radar-based cruise control system. You don't have to be a Luddite to be overwhelmed by the tsunami of tech, but if you are one you've got a head start.

Lexus GX 460 unveiled, replaces GX 470 with more power and better gas mileage

is dropping in the new-design Toyota V-8 for the 2010 GX 460 SUV, which it unveiled Monday at Guangzhou International Automobile Exhibition in China.

The G X 460 replaces the GX 470 and the new 4.6-liter V-8 also used in the Toyota Tundra pickup replaces the -- duh -- 4.7-liter V-8. That inefficient 4.7 actually got worse fuel economy in the Tundra usage than the 5.7-liter V-8.

The change adds adds power: the 4.6 in the '10 GX 460 is rated 301 horsepower and 329 pounds-feet of torque vs. the 4.7's just 263 hp and 323 lbs.-ft. in the '09 GX 470.

It also ups the fuel economy: the 4.6 is rated 15 mpg in town, 20 on the highway, 17 combined (5.88 gallons per 100 miles) . That's up from the 4.7's 14/18/15 (6.67 gal./100 mi.)

The GX, similar to the Toyota 4Runner that no longer offers a V-8, is a mid-size SUV with full-time four-wheel drive. The vehicle continues to be a truck-style, body-on-frame machine in a time when most buyers are shifting to unibody crossover SUVs. A third-row seat now is standard and comes with power-fold.

Lexus LFA is lease only in US

The Lexus LFA supercar will only be available to lease in the US, the company has confirmed.

Only 500 units of the £343,000 supercar will be built, and any customers ordering one in the US will have to wait two years before seeing their names in the log book.

Car collecting is big business in the US and a Toyota UK source told Autocar that the decision has been taken to prevent buyers there from keeping their LFAs as unused museum pieces, waiting to appreciate in value.

The move has also been designed to fend off speculators buying the car and then selling it on almost immediately for a large profit. Lexus’s US vice president for sales Brian Smith said speculators buying and selling LFAs would be “damaging the ownership experience”.

“If someone buys it in the first month and then decides to sell it, that could be damaging for the ownership experience,” he said.

“If it is not controlled and hits the speculation market, all bets are off. We want people out driving the car and not parking it in a museum or selling it at an inflated price.”

Last year, Nissan tried a similar scheme to stop GT-Rs getting into the hands of speculators. It explored the idea of getting eBay to ban the sale of GT-Rs for six months, but decided this w

Lexus LF-A Roadster

Lexus LF-A Roadster

We got to see the Lexus LF-A concept at the 2005 Detroit Auto Show. And catch a few eyes it definitely did. The new design philosophy visible in the LF-A was called L-Finesse by Lexus.

While the initial information was that it would be a V8 powering this supercar, the latest rumors are that the LF-A would be powered by a hybrid engine. The V8 would be there, but there would be an electric motor too - and the specifications for that is not available yet.

The V8 would be a 5 litre engine producing 435 bhp. The power distribution and how big a role the electric motor would play is unknown yet. Well, a hybrid supercar is in some ways a little late to the party - especially when an all-electric supercar (?), The Tesla Electric Roadster, has just been launched.

Anyway, top speed of the LF-A is expected to be in excess of 200 mph, and the 0-60 acceleration time would be under 4 seconds. It is nine inches shorter than the Porsche 911 Turbo, and at 48 inches, almost the same height as a Ferrari F430.

Lexus believes that the V8 would help them bring Toyota's Formula One experience to the supercar. The hybrid LF-A might make its appearance at the 2007 Tokyo Motor Show.

Lexus LF-A Roadster Concept

Lexus LF-A Roadster Concept

With supercar good-looks, the V10 LF-A has methodically marched from concept, to prototype, to imminent-super-secret production model, to endangered species list. The main hurdle seems to be the $225,000 cost which Toyota views as prohibitively expensive and unprofitable. Which is a cop-out of course. Regardless of the economy, there seems to always be an inexhaustible flow of wealthy buyers IF you have something worthy of their attention. The real question is whether Lexus is ready to produce a supercar.

Though Toyota maintains that the LF-A will remain only a development platform they are certainly parading it around like the next big thing, including a sighting by myself at the U.S. Open a couple of weeks ago. The “F” logo, located on each front fender of the Roadster, indicates the vehicle’s status as a part of the “F” special vehicle program within Lexus that falls outside the normal engineering and development process.

Compared to the coupe concept that was introduced last year, the LF-A Roadster features a number of design differences including reshaped headlights, a new front fascia, modified side skirts and air intakes, and a somewhat reshaped trunk. The LF-A Roadster is still based on the same lightweight carbon-fiber and aluminum body used for the LF-A coupe, which maintains strength and rigidity even in topless form. Like its coupe sibling, the LF-A Roadster is also powered by a high-revving 5 liter V10 engine capable of more than 500 horsepower and speeds greater than 200 mph. It is mounted in front of the passenger compartment but behind the front-axle centerline in what engineers refer to as a front-mid configuration controlled by paddle shifters. The LF-A Roadster stands just 48 inches tall, but the Roadster configuration adds a speed adaptive rear wing. The rear is also marked by a pair of wrap-around, arrowhead-shaped taillights that bracket a pair of large grilles. These grilles vent the heated air from the car’s two rear-mounted radiators into the LF-A Roadster’s aerodynamic wake. The radiators are fed cool air by two large intake ducts mounted just above the rear wheel wells.

Lexus Concept Interior

While there’s still no definitive sign of a production version of a Lexus LF-A supercar, admirers can only hope that Lexus sees the need to having a high performance, limited production supercar in the company stable.

2010 Lexus ES 350

With ruminations on an improvement of economy, many car buyers are looking to mid-range and entry-level luxury cars. The benchmark in the category has long been the Lexus ES 350, and though 2010 brings a few new competitors, Lexus is keeping pace with updated styling and features.

The Lexus ES 350 debuts revised styling, new luxury amenities and the all-new telematics system, Lexus Enform™ and Safety Connect™, for 2010. Newly standard rear seat-mounted side airbags bring the number of airbags in the ES 350 to 10.

The powertrain remains the same with a 3.5-liter V-6 engine rated at 272 horsepower and 254 pound-feet of torque. A six-speed automatic transmission sends the drive to the road, and features manual shift capability.

2009 Lexus GS 450h

The Toyota GS 450h is equipped with a unique hybrid powertrain designed especially for the rear-wheel-drive cars. The system consists of a 3.5-litre V6 internal combustion engine that works on petrol, and a permanent-magnet electric auxiliary motor. Combined, these two engines produce more than 300 horsepower and make the car run as with a 4.5-litre powertrain while ensuring fuel efficiency of a 2-litre engine.

It takes the car only 5.2 seconds to accelerate from zero to 60 miles per hour. The car is equipped with EPS with Variable Gear Ratio Steering, air conditioner, heated/ventilated front seats, rain-sensing wipers, rear side air-bags, 18-inch alloy wheels etc.

2010 Lexus IS250C

The new Lexus IS 250C, which will go on sale this summer, combines the sharp styling of the IS saloon range with open-top engineering ingenuity. The result is top-down driving pleasure with uncompromised dynamic performance.

True to Lexus’s legendary quality and attention detail, the new IS 250C has been engineered to achieve excellent aerodynamics, torsional rigidity, NVH levels and safety performance in both coupe and convertible configurations.

The IS 250C shares its 204bhp (208 DIN hp) 2.5-litre V6 engine and six-speed automatic transmission with the IS 250 saloon. It is styled to minimise wind turbulence when driving with the roof stowed, while extensive revisions to the body structure and suspension provide a high level of torsional rigidity.

2010 Lexus IS Convertible

The all-new 2010 Lexus IS 350C and IS 250C hard-top convertibles give Lexus a coupe and convertible in the entry luxury segment for the first time. The IS C models combine the expressiveness of a convertible with the athletic styling of a coupe.

The Lexus IS convertible models feature the same powertrains as the IS sedans. The IS 350C's 3.5-liter V6 delivers exhilarating performance with outstanding 306 horsepower at 6,400 RPM along with 277 lb.-ft. of torque at 4,800 rpm. The IS 250C's 2.5-liter V6 engine has a great combination of fuel efficiency and performance. The IS 250C's V6 produces 204 horsepower at 6,400 RPM and 185 lb.-ft. of peak torque at 4,800 rpm. Both engines utilize aluminum cylinder blocks and heads, while employing dual Variable Valve Timing with intelligence (VVT-i), which controls timing on both the intake and exhaust camshafts.
