Land Rover’s all-new Discovery, as unveiled late September, is powered by a selection of Jaguar Land Rover (JLR)’s latest four- and six-cylinder diesel and petrol engines. The 2.0-liter Ingenium diesel powerplant delivers what JLR refers to as ‘enhanced fuel economy and CO2 emissions’.
The aluminium Ingenium engine features lightweight construction with stiff cylinder blocks and decoupled injectors, which ensure low levels of vibration and noise intrusion, enhancing the relaxed character that is such a core part of the Discovery family. All engines are paired with an eight-speed ZF-sourced automatic gearbox.
JLR has applied a series of technologies designed to enhance fuel efficiency across the entire range. All engines feature stop/ start with smart regenerative charging used across petrol and diesel powertrains. These features are supported by ECO Data, which allows drivers to see real-time fuel economy data on the central touchscreen display.
The introduction of Land Rover’s award-winning Ingenium diesel engines ensures New Discovery offers highly competitive in class, in regard to emissions figures. With 240PS and 500Nm of torque the new Sd4 powerplant allows the New Discovery to accelerate from 0-100km/h in 8.3 seconds (0-60mph in 8.0 seconds) with comparable performance compared to the outgoing Discovery 3.0-liter V6 diesel. Despite this hike, the new four-cylinder unit provides CO2 emissions of 171g/km and is capable of 43.5mpg.
The engine uses the latest-generation high-pressure common rail direct fuel injection operating at pressures of up to 2200 bar using solenoid injectors. It features a sequential twin turbocharger with variable nozzle turbine (VNT) technology and a high-efficiency water-cooled intercooler for superior engine responses. Dual-isolated engine mounts and further optimised transmission mounts combine with variable cam timing on the exhaust side and twin balancer shafts for the upmost refinement.
The new Discovery is also available with a 258PS 3.0-liter V6 diesel engine, badged Td6 (above). The single-turbo engine features low-pressure exhaust recirculation, a two-stage oil pump and revised fuel-injector nozzle for improved responses, refinement and efficiency.
This latest generation powertrain achieves a seven per cent reduction in CO2 emissions over the previous 256PS Discovery TDV6; down from 203g/km to 189g/km, and is capable of up to 39.2mpg (7.2l/100 km).
The 258PS engine delivers stronger performance than before and the benchmark 0-100km/h sprint takes only 8.1 seconds (0-60mph in 7.7 seconds) a reduction of 1.3 seconds. With a significant 600Nm of torque on offer, the new Td6 diesel delivers relaxed cruising refinement and towering all-terrain capability.
Land Rover’s supercharged 3.0-liter V6 engine is the range’s performer. The 340PS Si6 engine develops 450Nm of torque and powers New Discovery from 0-100km/h in 7.1 seconds (0-60mph in 6.9 seconds).
JLR is keen to highlight that the lightweight construction of New Discovery has helped play a decisive role in delivering lower emissions and improved fuel efficiency across the model range. As a result CO2 emissions are down six per cent, to 254g/km, with fuel economy increasing to 26mpg (10.9l/100km) compared to its predecessor.
All engines are fitted with a ZF eight-speed automatic gearbox, which has been engineered with Land Rover’s powertrain experts to combine smooth shifts with sharp responses and optimised fuel efficiency.
The eight closely spaced ratios ensure that gearchanges are almost imperceptible, with each completed in a fraction of a second. For greater control, and if added performance is required, the gearbox will accept multiple downshifts and maintain a smooth transition between the ratios.
