2017 Lexus GS Hybrid Performance Review

Note: This performance review was created when the 2017 Lexus GS Hybrid was new.


Performance: 8.4

The 2017 Lexus GS 450h gets the outstanding gas mileage that you’d expect from a hybrid vehicle, but its V6 engine and two electric motors also combine to produce more than 330 horsepower – meaning you won’t be confined the to slow lane on the highway. The GS Hybrid has a comfortable ride and poised handling, though it can’t match the agility of some class rivals.

  • "The hybrid-powered 2015 Lexus GS 450h is one such car that can stretch a gallon of gasoline but still manage to provide some driving excitement, too." -- Edmunds (2015)
  • "… the GS 450h hybrid amplifies fuel-economy figures without any appreciable loss in performance." -- Kelley Blue Book (2015)

Acceleration and Power

The GS Hybrid features a 3.5-liter V6 engine and two electric motors that combine to produce 338 horsepower. The engine is paired with a CVT, which functions like an automatic transmission.

The GS Hybrid has plenty of power and feels pretty quick whether you’re driving around town or on the highway. Of course, when people think about a hybrid, fuel economy is usually part of the equation. The GS Hybrid earns an EPA-estimated 29 mpg in the city and 34 on the highway. Those are outstanding ratings compared to other luxury midsize cars.

  • "Who says performance and fuel economy can't live in harmony? In the 2017 Lexus GS 450h, an Atkinson-cycle 3.5-liter V6 is teamed with an electric motor for a combined 338 horsepower. The combo delivers an impressive 31-mpg combined rating, yet accelerates the hybrid sedan faster than its gasoline-only counterpart." -- Kelley Blue Book
  • "The highlight of the GS 450h is its efficient hybrid powertrain. … Even with the additional 400-pound mass of its hybrid system, the GS 450h is actually slightly quicker than the less powerful GS 350." -- Left Lane News
  • "Together, the electric motors and 3.5-liter V6 gas engine produce a hearty 338 horsepower, which is plenty to keep more spirited drivers entertained." -- Edmunds (2015)

Handling and Braking

The rear-wheel-drive GS Hybrid doesn’t quite have the handling prowess of its gas-powered counterpart due to the extra weight of the electric motor and batteries. However, it still remains composed around turns and performs capably on winding roads. The ride is smooth, and unlike some other hybrids, the GS Hybrid’s regenerative braking system is barely noticeable.

Drivers looking for better performance should opt for the GS Hybrid F Sport, which features dynamic rear steering and a sportier version of the GS Hybrid's standard adaptive suspension. These features allow the F Sport to handle sharp turns more easily and give the car a more athletic feel.

  • While we'd say the BMW 5 Series and Cadillac CTS have a bit of a sporting edge on the GS 350, it can certainly hold its own against an AWD Audi A6 or a Jaguar XF." -- Kelley Blue Book
  • "The hybrid GS sedan's standard adaptive suspension continually adapts to road and driving conditions to provide the best ride and handling possible." -- Edmunds (2014)
  • "Braking is incredibly good, however, a complaint I often have in hybrid models. Most owners won't even notice the regenerative brakes." -- Cars.com (2013)
