The new Lexus RX450h SUV will emit less CO2 than a 1.4-litre Vauxhall Corsa, according to official figures released by the Japanese manufacturer.
Official figures issued today show the hybrid SUV will produce 148g/km of CO2 and return 44.8mpg on the combined cycle.
The figures mean that the RX450h is 28 per cent more fuel-efficient than the RX400h, Lexus’s first hybrid SUV crossover. It is also 28 per cent more economical than the most frugal version of the similarly sized BMW X5, and emits 117g/km less CO2 than a straight-six petrol-engined Land Rover Freelander.
Power for the new RX450h comes from a 3.5-litre V6 petrol engine (up from 3.3 litres), coupled with two electric motors to produce 295bhp. Lexus claims a top speed of 124mph and a 0-62mph time of 7.8sec.
UK customers will only get the four-wheel-drive model when the RX450h goes on sale in the summer, priced at around £35k.
