Which GS 450h does Edmunds recommend?
Edmunds' Expert Review
Overall rating7.4 / 10
For the most part, owning a sporty luxury sedan means sacrificing fuel economy. But the 2018 Lexus GS 450h is a notable exception. This hybrid luxury sedan is enjoyable to drive and saves you gas at the same time.
From economical to sporty, there's a Lexus GS model that appeals to most luxury sedan buyers. The 450h's hybrid powertrain combines a 3.5-liter V6 with large electric motor producing a healthy 338 combined horsepower. The rear-wheel-drive 450h can accelerate from zero to 60 mph in a claimed 5.6 seconds and return combined 31 mpg (29 city/34 highway).
And while other manufacturers have sacrificed dynamics for hybridization, the GS 450h maintains its performance capability thanks to its sporty handling. The rest of the 450h is very similar to the GS 350, including the large 12.3-inch infotainment display, navigation system, and plenty of standard and optional features.
On the downside, the 450h's pricing is much higher than a comparably equipped gasoline-only GS 350 as well as starting prices for rivals such as the BMW 530e plug-in hybrid and Acura RLX Sport Hybrid. We're also not fond of the 450h's infotainment interface. But on the whole, the 2018 Lexus GS 450h is a smart pick if you're looking to get high levels of luxury, performance and fuel economy in one package.
