The GS 450h will still follow the same pricing as the sibling it replaces but the RX450h will use a revised pricing which is now $485 higher fr the all wheel drive units and $675 for the front wheel drive models.

The RX 450h will feature the Hybrid Drive setup which utilizes the V6 with 3.5L displacement and two electric motors for the FWD units and the same engine plus three electric motors for the all wheel drive unit. The setup gives you a crossover that has a powerful V6 with a better fuel mileage.

According to the car manufacturer, the front wheel drive RX 450h has an estimated fuel efficiency of 28 miles per gallon on the highway and 32 mpg for city driving, or a combined fuel rating of 30 mpg. If you opt for the all wheel drive RX 450h, the efficiency hits 30 mpg on the city streets while going 28 mpg on the highway or a 29 mpg combined fuel rating.

If you think the hybrid sedan will suit you more, the GS 450h of Lexus will have a sticker price starting at $58,950 inclusive of destination charge. The power output of the hybrid sedan goes down a bit to 338 horsepower compared to 340HP of the older sibling it replaces but the fuel economy gains some good grounds.

The 2013 GS 450h goes for 29 miles per gallon on city driving and 34 mpg while on the highway or a combined rating of 31 mpg. These numbers makes it the most efficient ride in its class today. It is also tagged as a SULEV or a Super Low Emissions Vehicle.

The older version of the GS 450h had a mileage of 22 mpg and 25 mpg on city and highway driving, respectively. Comparing the fuel efficiency, the new brood of GS is about 32% better in terms of fuel efficiency on city streets and about 36% more efficient while cruising on the highway.

The concept cars from Toyota are results trying to come up with solutions for possible problems in the future. They talk in reference to the $4 per gallon fuel price last summer and treat it as a preview of what things may come.

An electric car concept, the FT-EV, will be unveiled during the Detroit Auto Show. This vehicle shares the DNA of the iQ which is an urban commuter already on public sale in Japan. The non-electric iQ is said to land to the US soil as a Scion.

The core plan of Toyota on the long run will be to focus on the development of non-plug-in vehicles like the Prius.

Toyota aims to sell a million hybrid cars by early 2010. The Japanese car maker says that the new Prius and Lexus HS250H on display in the Detroit Auto Show is a glimpse of what’s to come in the future.

The company shares information that the new gen Prius will come into production by late 2009 earlier than the plotted 2010 schedule. The new prius will be built to run on a NiMi battery for the hybrid version and lithium-ion cells for the plug in.
