The rare combination of luxury, performance, and hybrid technology, the 2010 Lexus GS 450h is a hybrid sports sedan with seating for five. Under the hood is a 3.5L V6 which produces 292 hp, however there is an electric motor also under the skin of the GS 450h which brings total power output up to 340 hp. The GS 450h has an EPA estimate fuel economy rating of 22 mpg in the city and 25 mpg on the highway, these numbers are not high for a hybrid but they are good for a luxury sports car.Read more Read less
Not much new for the GS this year. The 450h hybrid gets a new grille, wheels, and taillights. The 350 and 460 don't get the exterior tweaks, but they do add iPod integration and Bluetooth. The cassette player is no longer available as of 2010.
Quiet, comfortable, excellent build quality; available all-wheel drive; available hybrid; latest in safety features
The GS packs a lot of amenities into a very reliable 4-door sedan starting with a powerful engine. No GS has an output under 300 hp, which adds a strong performance punch to the sedan. Safety tech includes Lexus's Vehicle Dynamics Integrated Management system, which coordinates a slew of sensors to keep the car headed where the driver intends it to go. For fuel misers, the full-hybrid 450h gets 22 mpg in the city and 25 mpg on the highway, a better than 10% improvement over its gasoline-only siblings.
