2011 Lexus GS 450h Overview

By Cars.com Editors
Vehicle Overview
The Lexus GS 450h hybrid sport sedan emphasizes performance over fuel efficiency, with its gasoline engine and hybrid motors combining to make 340 horsepower, which about matches the 342-hp V-8 engine in the GS 460. The GS 450h has no hybrid competitors. The hybrid is a smidge faster than the GS 460. Lexus says the GS 450h can accelerate from zero to 60 mph in 5.2 seconds, while the GS 460 takes 5.4 seconds. The GS 450h's combined city/highway gas mileage is 23 mpg. That means it sips gas on par with the V-6-powered GS 350. There's a more compelling case when it's compared with the V-8-equipped GS 460, which has a lower combined city/highway estimate.

New for 2011
Other GS models added a brake override system for 2011, but it already was standard on the GS 450h.

Exterior
Virtually identical to the GS 350 and GS 460 sedans, the GS 450h sports Lexus' familiar face with its angular headlights and grille. An adaptive suspension continually senses road conditions to modify damping appropriately. A Sport mode incorporates tighter damping, and an optional active stabilizer system mitigates body roll even more. Exterior features include:
  • Moonroof
  • High-intensity-discharge headlights
  • Rain-sensing windshield wipers
  • Special 18-inch wheels


Interior
An electric-power meter replaces the tachometer in the leftmost instrument pod, while a dashboard information screen displays energy consumption statistics and an animation of real-time power routing. Otherwise...

Otherwise, the GS 450h's interior is identical to other GS models, including the cramped backseat. Because of intrusion from the hybrid system's batteries, trunk volume shrinks. Interior features include:
  • Standard heated leather seats
  • Standard ventilated front seats
  • Standard dual-zone automatic climate control
  • Available electric rear sunshade
  • Standard 10-speaker audio system
  • Available navigation system
  • Available 14-speaker audio system


Under the Hood
The GS 450h's 3.5-liter V-6 engine is shared with other Lexus models. Mechanical features include:
  • 3.5-liter V-6 makes 292 hp, not including the electric motors
  • V-6 teams with two electric motors — one to start the gas engine, the other to boost acceleration — for a combined 340 hp
  • Regenerative braking to charge the batteries for electric motors
  • Engine shutoff when car is at a standstill
  • Can move solely on electric power during light-load situations
  • Continuously variable automatic transmission


Safety
A full complement of electronic safety features centers around Lexus' Vehicle Dynamics Integrated Management system, which is standard. Safety features include:
  • Electronic stability system
  • Antilock brakes
  • Electronic brakes
  • Adaptive front lighting system swivels the headlights several degrees during turns to better illuminate corners
  • Side-impact airbags
  • Side curtain airbags
  • Available adaptive cruise control can sense impending collisions and alert the driver

Warranty FAQs

What is a Bumper-to-Bumper warranty?

Often called a basic warranty or new-vehicle warranty, a bumper-to-bumper policy covers components like air conditioning, audio systems, vehicle sensors, fuel systems and major electrical components. Most policies exclude regular maintenance like fluid top offs and oil changes, but a few brands have separate free-maintenance provisions, and those that do offer them is slowly rising. Bumper-to-bumper warranties typically expire faster than powertrain warranties.

What is a Powertrain warranty?

Don't be misled a 10-year or 100,000-mile powertrain warranty doesn't promise a decade of free repairs for your car. It typically covers just the engine and transmission, along with any other moving parts that lead to the wheels, like the driveshaft and constant velocity joints. Some automakers also bundle seat belts and airbags into their powertrain warranties. With a few exceptions, powertrain warranties don't cover regular maintenance like engine tuneups and tire rotations.

What is included in Roadside Assistance?

Some automakers include roadside assistance with their bumper-to-bumper or powertrain warranties, while others have separate policies. These programs cover anything from flat-tire changes and locksmith services to jump-starts and towing. Few reimburse incidental costs like motel rooms (if you have to wait for repairs).

What other services could be included in a warranty?

Some automakers include free scheduled maintenance for items such as oil changes, air filters and tire rotations. Some include consumables including brake pads and windshield wipers; others do not. They are typically for the first couple of years of ownership of a new car.

What does CPO mean?

A certified pre-owned or CPO car has been inspected to meet minimum quality standards and typically includes some type of warranty. While dealers and third parties certify cars, the gold standard is an automaker-certified vehicle that provides a factory-backed warranty, often extending the original coverage. Vehicles must be in excellent condition and have low miles and wear to be certified, which is why off-lease vehicles feed many CPO programs.
