 2008 Lexus LS600h L by Cordell Koland Lexus has jumped the gun on the 2008 automotive year with the launch its new LS600h L hybrid, which puts Toyota¹s luxury brand solidly in the ultra premium luxury market. For a sticker price that can run well in excess of $100,000 with options, the buyer will get an automobile that has pushed the envelope for opulent creature comforts and tops the charts in terms of applied technology. The car will be available in the summer. The LS600h L, which will account for only a small fraction of the division's total sales, delivers a new level of prestige to the company that has been a huge sales winner. Total Lexus sales through April reached nearly 100, 000 total units with a 7 percent increase over 2006. The ultra-luxury sedan brings an enhanced level of sophistication to the brand. For the first time Lexus targets consumers at the pinnacle of the economic pyramid and aims to compete with V-12 sedan offerings from BMW and Mercedes-Benz,. Let's deconstruct the brand name, LS600h L as informative exercise. First, the initials LS refer to luxury sedan and have been attached to the Lexus flagship since the LS400 was introduced in 1989. The number 600 is an oblique allusion to power displacement, as if the car was powered by a massive six-liter V12 engine. But it is not. Rather, Lexus contends 'it will deliver power and performance on a par with modern 12-cylinder engines.' The letter 'h' or course stands for hybrid. The idea here is that the combination of hybrid technology and an advanced V-8 engine will deliver the power of a V-12 and yet deliver superior fuel efficiency and the last word in low emissions. In terms of power delivery, Lexus claims zero to 60 mph in just 5.5 seconds and 50 to 70 mph in 3.5 seconds. This acceleration can become addictive as I found during the test period. Although I loved the fact that I was getting nearly 20 miles per gallon in mixed driving, I just couldn't keep myself from flooring the accelerator to experience first hand the huge power burst that was available at any reasonable speed. Were it not for my deplorable behavior, I think I would have achieved an additional mile or two better gas mileage. And finally, the letter 'L' denotes a stretched wheelbase to deliver an additional five inches of rear legroom. Long wheelbase luxury sedans are designed around the needs and comfort of rear-seat passengers. And yes, if you ride in the new sedan's rear seat you will feel like the CEO of a Fortune 500 or the heir of a very large trust fund. The Lexus hybrid system combines an all-new 5.0-liter V-8 gasoline engine with two electric motors and a newly designed large-capacity battery pack that is light and quiet. The emissions challenge in starting a cold engine has been an ongoing concern. Typically, cold engines spew excessive hydrocarbons and other noxious gases in comparison to an engine that has reached thermal efficiency. A new Hydrocarbon Adsorber and Catalyst (HCAC) system is linked to the exhaust to help prevent hydrocarbons contained in the exhaust from being released into the atmosphere during cold start up when the catalysts are not up to temperature. The hybrid powertrain uses two motor generators, termed MG1 and MG2. Each motor performs specific functions and can operate as either a motor or an electric generator, although MG1 is used as a starter motor and provides no motive force. The engine-driven generator can charge the battery pack or provide additional power to the drive motor, MG2, as needed. Additionally, the LS hybrid utilizes regenerative braking, which means that it captures deceleration force during braking and turns it into electric energy to charge the batteries. But what I find most impressive is that the Lexus hybrid can run for an amount of time on only electric power. This of course delivers the last word in a quiet ride and can help save the air when creeping along in August on a bad air day in Manhattan. By pushing a switch, power reverts to full electric mode for short-distance, slow traffic situations. Whether most of its owners will know or care about the technology on board is an open question. But from a luxury and performance standpoint, the LS600h L certainly delivers. Its ride is sumptuous and my first impression is that the standard all-wheel drive system has substantially improved handling over any of its predecessors. Vehicle:
