2010 Lexus RX450h
RX Hybrid Builds On Strengths
This may come as no surprise, but the 2010 Lexus RX 450h hybrid doesn’t look a whole lot different than the model it replaces. In fact, if you were to just give it a casual glance, you might think you were looking at a 2009. Lexus was not about to make radical changes to their popular RX, but they did make subtle changes to enhance the appearance, and a number of more significant improvements to the rest of the vehicle.
Styling-wise, the RX gets broader shoulders for a slightly brawnier look. On the inside, There’s a new asymmetrical center stack, which is very functional, but aesthetically, might be an acquired taste for some. A new mouse-like controller on the console simulates using a computer to program the navigation system, audio and climate controls. This is the most intuitive controller that I’ve ever used.
Lexus upgraded its hybrid power plant in the 2010 RX450h. A slightly larger 3.5-liter V-6 engine, teamed with electric power sources generates 295 hp, 27 more than last year’s model. It also delivers 8-12-percent better fuel economy, thanks to a lighter battery pack and hardware. The 450h is rated at 30-mpg City and 28- mpg Highway. This is substantially better than the gas-powered RX350, which provides 18-24 mpg.
My test car was equipped with all-wheel drive, so it had three electric motors. One drove the front wheels; another powered ones in back, and the third handled a variety of functions, including that of starter motor. These motors also serve as generators and charge the battery pack. The batteries also get charging from a system called “regenerative braking.” When the driver applies the brakes, or when the car is cruising, energy flows back to the batteries.
To improve the handling of the RX, Lexus installed new electric power steering that feels quicker, and provides better feedback to the driver. They also replaced the strut-type rear suspension with a more sophisticated double-wishbone configuration that improves agility. (The absence of strut towers in the cargo area also increases storage space.) And to prevent rolling backwards when starting on an incline, the RX gets Hill-Start Assist Control.
The RX hybrid is a pleasure to drive. It is very responsive, especially in passing situations, where it does not hesitate. Hit the accelerator, and this 4800-lb SUV moves out in a hurry. Power comes on in a steady stream, via its continuously variable transmission. Furthermore, the 450h is quiet. The hybrid system generates very little in the way of drive-train noise, which enhances the feeling of luxury. Yet, it is capable of hauling your 3500-lb boat or trailer.
My RX came crammed with luxury features. Standard ones included keyless entry and start, a ten-speaker sound system, and Lexus’ excellent VDIM anti-skid system. Optional equipment was highlighted by leather trim, a voice-activated navigation unit and a rear-seat entertainment system.
The base price for the 2010 Lexus RX450h is $44,125. My heavily optioned test car had a bottom line of $54,115.
