In addition to the new LS 460, there will be a long-wheelbase version called the LS 460L with a limousine-like rear seat and a hybrid version called the LS 600h, which combines a 5.0-liter version of the V8 engine with a new version of the Lexus hybrid drive system.
The all-new 2007 Lexus LS models are bristling with technology. The LS 460 is the first car in the world with a computer-controlled eight-speed automatic transmission. An optional parking guidance system uses onboard cameras to help the driver parallel-park or park between cars, a system offered by no other manufacturer. The 460L offers reclining heated bucket seats, a cool box, dual-zone rear HVAC controls, a folding table, an ottoman, a shiatsu massager, and, of course, DVD with wireless headphones.
On the road, we found the LS 460 extremely quiet and extraordinarily smooth. Its 4.6-liter V8 can propel it from 0 to 60 mph in a mere 5.4 seconds, according to Lexus, yet it gets an EPA-rated 27 mpg Highway. The eight-speed automatic is super smooth and plays a big role in the fuel-economy story. The electrically powered steering system and adjusts according to speed. The ride quality and handling are exemplary, and an optional Touring package brings a new level of sportiness to the LS 460. The brakes have been improved, and now they are fully electronically controlled, working with all of the other computers on the car to determine how much brake force to put at each individual wheel, rain, snow or sunshine.

As the flagship, the new, 2007 Lexus LS 460 gets the most finesse of any of the L-finesse designs thus far. Its lines flow smoothly from its amazingly complex, crystal-like headlamp units, under the car, up over the roof and around the mirrors, with a short trip over the tiny rear deck to the integrated rear spoiler. After all that detail work on the exterior, they gave the car a drag coefficient of 0.26, tied with the best in the industry for a four-door sedan.
Optitron is the name used by Lexus to describe its electroluminescent gauges and displays, and they are lit by bright white LEDs for excellent readability, day or night. Almost all of the needles illuminate, dominated by the large tachometer and speedometer needles. Every single switch on the car is lighted for ultimate convenience. A new thin-film-transistor (TFT) multi-information color display delivers as many as 13 information and setting displays during driving.
New four-spoke tilt-and-telescope leather-and-wood steering wheels (heated on the uplevel versions) feature redundant controls for audio, information, cruise control, radar cruise control option, telephone, and a new brake-hold feature. To use the brake-hold feature, just come to a stop, push down the brake pedal, touch the button on the steering wheel, and the brakes stay on regardless of vehicle attitude until you touch the gas pedal.
The center stack of controls is beautifully integrated, as is every single piece of interior trim, and though there are lots of buttons, they are clearly marked in large type and lighted, so there will be little confusion after a couple of drives. The navigation display is large and bright, and the graphics are crisp and sharp. An auxiliary input is provided for MP3 players, such as the Apple iPod. The standard sound system is a 276-watt, 10-speaker system that sounds wonderful until you try the optional Mark Levinson system, which we think is the single best automotive sound system on the market.
The new Lexus LS is a big, roomy and comfortable luxury sedan, with generous interior dimension and 18 cubic feet of trunk space, enough for four sets of golf clubs.
The 460L version offers more room of course, and the option of a luxurious rear-seat setup with two reclining heated bucket seats, a cool box, sunshades, additional climate ducting, and dual-zone rear HVAC control. Yet another configuration, the executive class seating package, adds a folding table and a right rear seat with a built-in ottoman section, shiatsu massager, an extra air bag, and a rear roof-mounted 9-inch DVD screen and two sets of wireless headphones. No car manufacturer this side of a $350,000 Maybach offers this kind of rear-seat setup.
This is the first car in the world with a computer-controlled eight-speed automatic transmission, a transmission that offers great acceleration with nearly imperceptible upshifts and downshifts, manual or automatic shift control, and that great highway mileage in eighth gear overdrive.
Moving off from rest with authority and acceleration seems like child's play for the LS 460. The engineers tell us that almost every part of the car, especially the engine, transmission and driveline, have been designed and then checked again and again for quietness, smoothness and balance. We found the LS 460 very, very quiet and nearly vibration-free. It seems much quieter than the competition, whether at 30 mph or 130 mph, its regulated top speed.
The electrically powered steering system is transparent. It doesn't feel any different than hydraulically powered steering, and it has progressive assist that decreases with speed. If you order the optional air suspension or the entire Touring package of suspension, tires, wheels, brakes and brake pads, you get variable gear-ratio power steering instead, giving the system the latitude between 2.5 and 3.6 rotations of the steering wheel. Without the Touring package, the ride and handling are exemplary, but with it, there is a whole new level of sportiness about the LS 460, so we recommend it highly.
Like everything else on, in or under the LS 460, the brakes have been improved, and now they are fully electronically controlled, working with all of the other computers on the car to determine speed, steering angle, throttle angle, yaw angle and all the other inputs to determine how much brake force to put at each individual wheel, rain, snow or sunshine. They, too, feel perfectly normal and extremely powerful. The Touring package will get you a set of spiral-fin ventilated discs on the long-wheelbase version.
Completely redesigned, the all-new 2007 Lexus LS 460 is surely the quietest, most serene luxury-class sedan that's been built so far. It offers an excellent combination of comfort, space, silence, and features. It's also the most electronics-intensive luxury car we've ever experienced, and if it weren't a Lexus, that would give us pause. But it is Lexus, and it promises to be as bulletproof and trouble-free as all of its predecessors. If you like silent, obedient transportation with lots of room, and you can afford the price, it's the one to have.
