The four-pot Discovery will be the cleanest model in the line-up at launch - although it seems inconceivable that the car won’t benefit from some of JLR’s extensive work on plug-in hybrid technology during its lifetime. Badged SD4 and paired with a ZF eight-speed automatic gearbox, the 2.0-litre model will have 237bhp and 500Nm of torque - enough for a 0-60mph time of 8.0 seconds - but return 43.5mpg and 171g/km of CO2 emissions.

The other two engines in the UK market will be a pair of 3.0-litre V6s - a diesel called TD6, with 255bhp/600Nm, and a supercharged Si6 petrol with 335bhp and 450Nm. The more potent diesel beats its smaller brother to 60mph (7.7 seconds) and gets close on efficiency, with fuel consumption of 39.2mpg and 189g/km of CO2 emissions.
