Definitely one of the most expensive hybrid cars on the market today is the Lexus LS600SL. Coming in at a hefty six-digit price tag, this Lexus is definitely not for the price-conscious consumer but is aimed at those who want a powerful vehicle with a reduced pollution footprint. Powered by a 389 horsepower V8 engine and a 197 horsepower permanent magnet electric motor, the Lexus delivers a quiet ride amidst all that power. Weighing around 5000 pounds, this luxury car shows that even at this level, hybrid technology is a feasible option. Although the hefty price tag may make even some connoisseurs take a longer time to bring out their checkbooks, in the end it is all about combining luxury and responsibility.
