The updates include the option of a new All Terrain Progress Control system (ATPC), which acts as a cruise control function for off-road driving. The system allows drivers to set a speed, while the car's range of sensors adjusts its terrain settings automatically at speeds of up to 19mph.
The ATPC system costs £175, and is available on all Range Rover and Range Rover Sport models with the exception of the SDV6 Hybrid Sport.
Land Rover has also improved the efficiency and performance of its 3.0-litre, six-cylinder TDV6 and SDV6 engines. The TDV6 now features a single turbocharger in place of the old twin-turbocharged setup, but output from the engine is unchanged, at 281bhp and 443lb ft. Economy has improved by 8.5 per cent over the old unit, to 40.9mpg with CO2 emissions of 182g/km.
The Sport's SDV6 engine has been re-calibrated to increase performance to 302bhp and 516lb ft - increases of 14bhp and 73lb ft respectively. Economy has also improved by seven per cent, to 40.4mpg combined, alongside CO2 emissions of 185g/kqm.
