2013 Lexus RX 450h offers new sport driving mode and driving assist features
With the new Sport Mode, Lexus RX 450h owners can "fully exploit power train capabilities" while enjoying up to 30 miles/gallon fuel economy in this full hybrid luxury SUV. Toyota released, on Friday, details of the Lexus RX 450h revealing a luxury SUV that's better than ever, with new safety and driver assist features that should make for a safer driving experience.
“In 2005, the RX 400h was the world’s first luxury hybrid vehicle,” said Mark Templin, Lexus group vice president and general manager. “The new 2013 RX 450h will continue to be the segment leader as it has all the benefits of the industry’s most popular luxury utility vehicle, and Lexus Hybrid Drive.”
Engine, Transmission, Hybrid Drivetrain and Performance
The RX 450h is equipped with the Lexus Hybrid Drive system, with a 3.5-liter V6 Atkinson-cycle engine, offering 295 total system horsepower. The company claims that even though it is a V6 engine, it offers V8-like performance. The hybrid side of the vehicle has a 288V DC Nickel Metal Hydride (Ni-MH) battery pack, and a 123-kW electric motor-generator. That powerful of an electric motor surely plays a role in creating that "V8-like performance."
The vehicle carries the Super Ultra Low Emission Vehicle (SULEV) certification in California, meaning that it's pretty darn clean in terms of emissions. The Front Wheel Drive (FWD) RX 450h offers 32 mpg city, 28 mpg highway, 30 mpg combined fuel efficiency, while for the All-Wheel Drive (AWD) model it is 30 mpg city, 28 mpg highway, 29 mpg combined.
To assist in maintaining optimum fuel efficiency, an Eco driving indicator displays current fuel economy and alerts the driver when fuel efficiency falls off.
Acceleration is a respectable 7.8 seconds 0-60 mph for the front wheel drive RX 450h, and 7.4 seconds for the all wheel drive model.
The all wheel drive system uses a separate 50 kilwatt electric motor on the rear to provide power to the rear wheels when road conditions or throttle response dictates. The AWD system responds to road conditions by increasing rear-wheel torque when the front tires start to lose traction and vice versa. Additionally a SNOW mode slows the throttle response to reduce the chance of wheel spin.
