WHILE its German rivals talk about producing hybrid versions of their existing luxury SUVs, Japan’s Lexus has released the second generation of its petrol-electric RX crossover. Available now in three model grades, mirroring the petrol-powered RX350 line-up launched in February, the RX450h is the first Lexus to return fuel consumption of less than 7.0L/100km, making it almost entirely exempt from luxury car tax. That means it’s also the most affordable Lexus hybrid to date and with pricing starting at under $90,000 it is no wonder Toyota’s luxury division is selling every example it can get.
