The all-new four.four-litre LR-TDV8, in particular designed for the Land Rover Range Rover, replaces the three.6-litre LR-TDV8 and combines extensively elevated overall performance with substantially decreased emissions. Acceleration from relaxation to 60mph takes 7.five seconds as compared to 8.6 seconds for the preceding three.6-litre LR-TDV8, whilst pinnacle pace will increase from 125mph to 130mph. More essential, mid-variety acceleration from 50mph-75mph has progressed extensively, falling from 6.three seconds to simply five.1 seconds. Yet CO2 emissions have dropped from 294g/km to simply 253g/km as compared to the outgoing LR-TDV8 three.6-litre, a large 14 percentage discount. Most astounding of all, blended gasoline financial system has progressed by means of 18.five percentage from 25.four mpg to 30.1 mpg making this the primary Range Rover to dip above the 30mpg barrier. The new engine additionally meets the stringent EU5 emissions standards, so emissions of NOx, CO2 and HC are the various lowest withinside the international for an engine of this type.
Despite those dramatic reductions, electricity and torque have soared, from 272PS and 640Nm, to 313PS at three,750rpm and a stunning 700Nm torque at simply 2,000rpm. More essential is the manner the electricity and torque have interaction with each other for astounding common overall performance. Maximum torque is to be had from 1,500rpm to three,000rpm however then most electricity kicks in from three,250rpm to four,000rpm generating a wall of overall performance from idle onwards. None of this has been performed on the cost of refinement aleven though and the four.four-litre LR-TDV8's electricity transport stays silky easy and whisper quiet in the course of the engine pace variety.
A new CGI solid iron block bureaucracy the idea for the brand new V8 and even though comparable in layout to the outgoing three.6-litre engine, is taller to house an extended stroke and 11mm longer to make room for duplex timing chains. The strong new engine has a cast metal crankshaft which even though larger than that of the outgoing three.6-litre, isn't anyt any heavier way to cautious optimisation. Aluminium pistons with metal connecting rods include optimised combustion chambers for excessive electricity and occasional emissions.
A particular technique to packaging a number of the ancillaries permits the four.four-litre LR-TDV8 to fit smartly into the engine bay regardless of its large outside dimensions. The oil clear out out, engine oil cooler and EGR (exhaust fueloline recirculation) cooler were designed as one unit which sits withinside the centre of the 'V' taking on the minimal of room. A crankcase breather is included via the centre of the meeting and contains a cyclone layout to split oil droplets from the fumes being ingested again into the engine.
Cylinder heads are every geared up with 4-valves in line with cylinder and dual overhead camshafts and crowned by means of composite cam covers, remoted from the cylinder heads by means of elastomeric gaskets to lessen transmission of noise. The metal glow plugs of the three.6-litre LR-TDV8 were outmoded by means of new ceramic glow plugs which attain a temperature a few 250°C better and offer immediate beginning from key-on in regular situations. Even at ambient temperatures -30°C the brand new layout of glow plug heats up two times as fast as earlier than.
Parallel sequential turbochargers - lightning rapid, extremely green
Key to the brand new engine's overall performance and performance is the Parallel Sequential turbocharger machine which is nearly same in idea to that of the fantastic, 2010 three.0-litre LR-TDV6 brought at the Discovery four. During regular riding, a medium-sized, variable-geometry turbocharger works alone, optimising performance. When the engine revs climb past 2,400rpm, valves withinside the exhaust manifold open and a smaller, secondary faster seamlessly speeds up to complete pace in only 20 milliseconds, complete bi-faster operation being performed in most effective 180ms without a lag or electricity step. This technique permits the second one turbocharger to stay dormant while now no longer required, enhancing engine performance by means of decreasing pumping losses. A stability pipe connecting the 2 manifolds equalises strain among the 2 exhaust structures.
Parallel sequential turbocharging - precis of advantages:
- Most of the time most effective one turbocharger is in use (as much as dual carriageway cruising speeds and common acceleration). Because it's far a medium, in preference to large-sized faster with variable geometry, reaction is outstanding without a discernable lag.
- Packaging is outstanding, one faster and manifold beneath every financial institution of cylinders.
- The mixture of turbochargers makes it feasible to optimise performance and overall performance in any respect instances.
- Because one turbocharger is in use maximum of the time, pumping losses are decreased.
- More green than collection turbocharger structures, whose smaller number one turbocharger will increase pumping losses and gasoline intake via raised exhaust again strain.
The 0.33 technology not unusualplace rail gasoline injection machine mirrors that of the three.0-litre LR-TDV6 running at a strain of as much as 2,000bar. Eight-hollow piezo injectors, (as compared to seven hollow withinside the three.0-litre LR-TDV6) are similarly optimised for emissions and make a contribution to the engine's EU5 repute and minimise noise. In the past, not unusualplace rail gasoline pumps had been designed to over-deliver the injector rails, the excess being re-circulated again to the tank. This technique raised gasoline temperature appreciably and supposed the gasoline needed to be cooled earlier than being lower back to the tank, losing strength. The new machine resources gasoline on demand, growing performance and decreasing the quantity of cooling required.

The LR-TDV8 is the primary Land Rover engine designed from the outset to apply low SAPS Sulphated Ash, Phosphorus, Sulphur) oil, decreasing the build-up of ash withinside the DPFs (diesel particulate filters) for longer lifestyles and progressed performance. Conventional, near coupled oxidation catalysts are used for exhaust aftertreatment. Lubrication is by means of the cutting-edge low-viscosity 5W-30 oil enhancing performance for the duration of the heat-up phase.
The four.four-litre LR-TDV8 has been designed for 'pinnacle-down' servicing and does not want to be lifted on a ramp, even for oil changes. The oil clear out out unit, installed at the EGR unit withinside the 'V', is first loosened to permit the oil to empty into the sump after which unscrewed and changed without a fuss. Under regular circumstances, oil isn't always tired from the sump withinside the traditional manner, however extracted from the pinnacle of the engine by means of a unique carrier pump on the dealer. Service durations are 15,000 miles.
A facility for draining oil from the lowest of the engine has been retained to permit servicing in far off regions without a get entry to to grease extraction equipment. There's no dipstick, the oil degree is monitored electronically by using an ultrasonic sensor, informing the motive force of each the oil degree and the quantity of oil that desires adding.
"The overall performance of our new LR-TDV8 can most effective be defined as awe-inspiring. We are assured that the mixture of decreased CO2 emissions, EU5 compliance and the large boom in overall performance whilst turning in a large development in gasoline financial system, is international class." Paul Walker, Chief Programme Engineer

Transmission Idle Control seamlessly and transparently disengages 70 percentage of the power while the auto is desk bound and the engine is idling in Drive, decreasing drag at the engine and saving gasoline. The 8HP70 has brains too. In warm situations it selects a decrease equipment to run the engine and air con pump quicker to quiet down the cabin fast. In bloodless situations it runs the engine quicker to lessen heat-up time and emissions.
Apart from CO2-busting performance enhancements, the 8HP70 gives overall performance advantages too. Taking simply 2 hundred milliseconds to finish the whole shift event, the 8HP70 ratios alternate with an imperceptible interruption of torque for smoothness equalling that of a dual-grab transmission and the removal of 'head-nod.' The 8HP70 fits the engine pace to its turbine pace in anticipation of oncoming downshifts for an certainly easy transition from one ratio to the next. Closer ratios additionally make a contribution to creating character downshifts smoother as do manipulate structures which pick-up the engine revs for the duration of downshifts.
Driver Type Detection video display units motive force inputs and the auto's structures to optimise the reaction of the gearbox to the motive force's fashion, whilst Curve Detection makes certain the gearbox avoids traumatic upshifts and holds directly to the equal equipment while taking a chain of bends. The gearbox additionally video display units the motive force's use of the brake collectively with the charge of deceleration to installation the ideal equipment for access and go out to the corner. The 8HP70 does now no longer should alternate to a decrease equipment sequentially and might bypass up to 6 ratios if necessary, for a good deal quicker reaction while getting ready to overtake.
Driver controls encompass steerage wheel-installed paddle-shift as widespread allowing the motive force to take manipulate of equipment transferring manually. The CommandShift lever is changed by means of a rotary knob for choosing park, opposite, neutral, power or game modes, the final of those optimising the gearbox reaction instances for max acceleration, progressed reaction and sharper upshifts. The selector knob is flush with the centre console while the ignition is switched off, growing up while it's far switched on. To keep away from confusion, the Terrain Response® Rotary Switch is changed by means of a brand new Terrain Response® Optimisation Switch.
