This article applies to the Lexus GS (2005-2013).

Trying to find ways to stretch our hard earned dollars is common in any economy, let alone where we find ourselves today. Keeping as many greenbacks in our wallets and out of the gas pump is a challenge that many of us face day in and day out. Electric cars aren't that feasible, and flex fuel just didn't turn out to be all that great. Along comes the hybrid, which gets you thinking. Are they really worth it? Are the up front costs too great to overcome in the life of the vehicle? Let this article be your guide in the decision between the Lexus GS 350 and the Lexus GS 450h hybrid.

Component Breakdown

Lexus GS 450h Hybrid – Price, MPG, Lifespan, Performance and Pros/Cons

If you are looking for a luxury sedan that all other hybrids look up to, look no further than the Lexus GS series. If it's power and good fuel economy that you want, then you absolutely must consider the Lexus GS 450h. This is one beauty of a hybrid that will set you back at least $60,000. Owners and admirers alike will attest that it is a small price to pay for such wheels. This beautiful ride boasts a brow-raising 34 mpg highway at an unbelievable 338 hp with a CVT transmission. No other luxury car in its class can match that power plant output with such an incredible fuel economy. This is V8 power with V6 mileage at its best.

Although this car appears to be the best on mileage at consistent highway speed, city driving is unremarkable. The standard model GS 350 is likely better. If the batteries are not fresh, the gas powered engine will take over from a dead stop at a light to moving again, which will consume your standard rate of gasoline. These factors make this particular Lexus model a primary luxury sedan with a nice power plant that just happens to be a hybrid. If you are contemplating a return on investment between this model and the comparable GS 350, you'll have to look elsewhere. For the nearly $12,000 additional price tag, that kind of difference will not be made up at the pump. Like all other Lexus models, the 450h hybrid boasts an industry leading warranty, and the batteries will likely outlast the driver. This is a solid, beautiful piece of machinery that isn't designed to save gas and money per se; however, it gives its owner the life of luxury with V8 power and V6 efficiency.

Lexus GS 350 – Price, MPG, Lifespan, Performance and Pros/Cons

If hybridization is not your thing, you've come to the right car. The Lexus GS 350 is one gorgeous ride in the lap of luxury. This model starts around $49,000 and its sportier package, about $54,000. You will surely turns heads rolling up in this chariot. With a 6-speed shiftable automatic transmission, pulling about 308 horses under the hood, this is plenty of car for the money. All this power with a 29 mpg highway rating; you can hardly do better with a standard all gasoline power plant. The steering responsiveness and chassis handles like a dream sports car, which is a very pleasant surprise for a mid-sized luxury sedan. The interior is something to behold as well: about the highest quality craftmanship on the road today. The standard Lexus bumper to bumper and powertrain warranty should give you peace of mind as to the workmanship and durability of this car. If the Lexus GS series is the car you want, you will probably be better off sticking to the 350 than the 450 hybrid if you are purely looking at it from a cost savings standpoint.

Maintenance

Maintenance schedules with Lexus are second to none. The high quality workmanship of these vehicles provide a nearly worry-free ownership experience. The maintenance schedule for both the 450 hybrid and the 350 are virtually identical. Oil changes for each are suggested at every 10,000 miles in normal conditions. The only difference between the two will be seen at the major milestones; the 350 will need the engine coolant changed at 100,000 miles, and the hybrid at 150,000 miles.

Common Questions

Does the Lexus GS 450h hybrid have good acceleration?

The acceleration on the 338hp power plant is very admirable for a hybrid luxury sedan. This car is noted as going from 0 to 60 in 5.6 seconds, which is as good as any V8 powered mid-sized sedan. With 31 mpg, it is a good choice in that respect.

How often do I have to charge the Lexus GS hybrid?

Under normal conditions, you will never have to plug in your 450h. The power plant charges itself so long as it is driven at least weekly for about 10-30 minutes. When parking, make sure that the doors and trunk are closed and lights are turned off. If you plan to park the vehicle for more than 30 days, charging the vehicle may be required.

How long do the batteries last before they need to be changed?

Under normal driving conditions, the batteries should last at least 250,000 miles.

Is the 450h worth the extra money over the GS 350?

If you are looking for a high-performance hybrid that can rival the output of a standard V8 mid-sized sedan, but have much better fuel mileage, then yes, the 450h is your ride. If you are thinking you can get a 450h at the same cost as a 350 in the long run, think again. You are not likely to make up that initial out-of-pocket expense in savings at the gas pump. If that is your primary motive, you would be better suited for the ES 300h from Lexus.
