Lexus UK has revealed the gas mileage of the 2010 Lexus RX 450h press release for the Geneva Auto Show:
With a total system output of 220kW/299 DIN HP, the improved Lexus Hybrid Drive gives the RX 450h a maximum speed of 200kph. Via continuously variable transmission it will accelerate seamlessly from 0-100kph in just 7.8 seconds and 0-400m in 15.9 seconds. Conversely, the RX 450h boasts the world’s lowest premium crossover petrol consumption, a combined cycle figure of 6.3L/100km, and remarkably low CO emissions of just 148g/km.
Converted, the RX 450h will be delivering 37 mpg U.S. on the combined cycle, which marks an improvement of 28 percent. Funny thing, this is a 10 mpg increase over the numbers issued by Lexus USA:
The new RX 450h gains improvements in fuel economy with EPA-estimated ratings of 28 mpg in the city and 27 mpg in highway (26 mpg on AWD) driving. Gains are even larger in cold weather driving conditions.
The reason behind this is the US’ new EPA measurement standard, which has been adjusted to more accurately reflect real world driving. Taking this into account, 27 mpg should be the expected average from the RX 450h.
