With the elimination of the Lexus GS, the full-size LS is now the only sedan in the lineup for customers after a really spacious luxury car. This model boasts unique styling and impeccable road manners in a reliable and extremely safe package. What about the engine? There are two choices, starting with a turbocharged 3.5-litre V6 generating 416 horsepower. Environmentally conscious drivers will likely prefer the 354-horsepower hybrid variant.
