Outwardly, TheCarConnection.com spies few differences between the hybrid 2008 Lexus GS 450h and its gasoline-powered sibling.
Kelley Blue Book says "the GS brings a legitimate sense of design passion to its sleekly flowing sheetmetal that arguably qualifies it as the best-looking Lexus sedan." Edmunds reports the GS hybrid has "rakish styling." Cars.com feels "the GS is more futuristic than its predecessor, touting its long hood and set-back cabin.”
Autoblog says "visual differences, for the astute Lexus admirer, include 18-inch light-alloy wheels," adding that "the badge on the trunk will also reflect the [Lexus 2008] hybrid powertrain"; beyond this, "all other features, including dimensions, match with the standard GS 430." Cars.com also remarks that the 2008 Lexus GS 450h is "virtually identical to the GS 350 and GS 460 sedans...[sporting] Lexus' now-familiar face with its steeply raked headlights and thick C-pillars." Because it shares so much with the good-looking GS line, this Lexus 2008 model's styling "is sexier than that of many other hybrids," as the reviewer at ForbesAutos puts it.
The similarity extends to this 2008 Lexus's interior; Cars.com notes this Lexus 2008 model's interior "is identical to other GS models." This is not necessarily a bad thing, as Car and Driver points out: "like other Lexuses, this one features a beautifully finished interior." Edmunds describes the 2008 Lexus in glowing terms: "genuine wood and aluminum trim complements the rich leather seating surfaces," though stating that "the highly polished wood can reflect glare annoyingly at times."
