Prestige takes many forms. For some, it’s a big fancy luxury car, one with a price tag that that rubs your wealth in everybody’s nose. For others, it’s a fuel-sipping hybrid, one that gets better mileage than anything else at the price or size. Leave it to Toyota-owned Lexus to combine the two in the LS 600h L, a full-size luxury sedan that takes on the BMW 7 Series, Mercedes-Benz S-Class, or Audi A8 and S8, and trounces their fuel economy numbers to boot. Fine, it’s still no Prius, but with stricter fuel economy rules on the horizon, the LS 600h L puts Lexus well ahead of the game.
