For such a big vehicle, the LS 460l is scary fast. Lexus says the regular LS 460 can jump from 0 to 60 in 5.5 seconds but I figured the long version would be slower. I was wrong. The 460l weighs 4,332 lbs, just 88 lbs more than the 460, and it's equally fast. I consistently got 0 to 60 times of 5.4 and 5.5 seconds in the 460l, which about matches the lightening speed of the Mercedes S 550 (see BusinessWeek.com, 5/10/06, "The New S 500: Sportier, Sexier, More Expensive").
Out on the highway, the LS 460l is so quiet and smooth you often find yourself going far faster than intended. When I first started driving the car I found myself going as fast as 110 mph without realizing it. The car felt as smooth and quiet over 100 as it did at 65. Even after (in the interest of avoiding speeding tickets) I began to be more careful, I regularly found myself inching up to 85 or so, unaware that I was going so fast until I glanced at the speedometer. When you have to pass, or accelerate out of a dicey situation on the freeway, you feel confident that this car will perform any reasonable task effortlessly.
