Lexus GS is top fuel mileage luxury sedan
The 2013 Lexus GS 450h offers the best of two worlds — best-in-class gasoline-electric hybrid fuel economy when you're not in a rush, and pedal-stomping acceleration when you are.
The newly revamped-for-2013 GS 450h mid-size sedan has an aggressive, sporty sedan look and retains the rear-wheel drive configuration that many sports car aficionados prefer.
In fact, many people don't realize the GS 450h is a hybrid unless they see the hybrid badges on the car's exterior.
Technology, handling, styling and quiet ride are all noteworthy in this middle-of-the-Lexus-line sedan that slots between the larger Lexus LS and entry ES sedans.
The 2013 GS hybrid is the first car to combine rear-wheel drive/front-engine layout with an efficient Atkinson cycle V-6.
Buyers can get a distinctive bamboo-covered steering wheel and interior trim on the GS hybrid.
The Lexus GS is a recommended buy of Consumer Reports magazine, which finds its reliability above average.
The GS 450h is the top model of the GS line in both horsepower and price. Starting manufacturer's suggested retail price, including destination charge, is $60,360 for the 338-horsepower GS hybrid; this does not include navigation system, trunk cargo net or front passenger seat memory.
By comparison, the base, 2013 GS 350, which is powered solely by a 306-horsepower V-6, has a starting retail price of $48,150.
Competitors to the GS hybrid are the major luxury brands with hybrid powertrains. For example, the 2013 Mercedes-Benz E400h is a luxury, mid-size sedan with 302-horsepower, gasoline-electric hybrid power. Starting MSRP, including destination charge, is $57,625. The GS hybrid is tops among luxury branded hybrid sedans in fuel mileage, according to the U.S. government. It is rated at 29 miles per gallon in city driving and 34 mpg on the highway.
These numbers, which are a 35 percent increase from the previous GS hybrid, are not far-fetched. The test car, with uplevel 18-inch wheels, easily averaged 28.4 mpg in driving that was mostly in the city and included constant use of air conditioning. This translated into a single-tank range of nearly 500 miles. All the driver did to achieve the mileage was activate “eco” mode, which changed throttle mapping and made other adjustments to conserve fuel. It is one of five selectable modes on the car.
The most memorable part of driving the GS 450h is how quiet the ride is — conversations can be held in nearly hushed tones inside — and how smoothly power comes on.
Virtually all transitions among engine, the two electric motors and the battery pack were seamless in the tester. Indeed, if a driver didn't notice the word “ready” in green in the instrument cluster after pushing the start button, the lack of engine sound and engine vibration could make it seem as if the GS 450h hadn't turned on.
