To try and offer higher levels of efficiency, Land Rover is providing the fifth generation version of its large Discovery SUV with a four cylinder Sd4 diesel engine. The experts at Car & Driving check out what's on offer.
Ten Second Review
There's nothing quite like a Land Rover Discovery and not much comes close to matching the versatility of this latest fifth generation version. Whether it's carrying seven people in comfort, crossing deserts or cutting it in the company car park, this SUV does the lot. It's also lighter on its toes and your wallet in four cylinder diesel Sd4 form. So, is the Discovery the ultimate four by four? Let's find out.
Land Rover faces ever tougher competition whenever it launches the next incarnation of its Discovery. With this fifth generation model, there are rivals from all corners that offer a sporty drive, great off-road ability or a luxury experience. Yet none of them quite combines all of those elements in one package the way the Brit does and this is what has always made the Discovery stand head and shoulders above its rivals.
This MK5 model is mostly made from aluminium. That's helped shave 450 kilograms from the car's weight, which makes it much better on fuel consumption and more agile to drive. There are also new motors under the bonnet, including the 2.0-litre Sd4 turbodiesel we're going to look at here, a unit that aims to keep this large SUV firmly among company car drivers' choices.
It feels wonderful to be sat in the driver's seat of this Land Rover Discovery. It gives a great view of the road ahead and all around, so you feel safe and in complete control. That sensation is helped along by the way this fifth generation model behaves, which has a lot to do with it being 450 kilograms lighter than its predecessor thanks to ditching a separate chassis in favour of an aluminium core structure. As a result, it goes round corners with little body lean and, thanks to its air suspension, glides over bumps that would upset some its rivals. Of course, this is still a large SUV, so some care is needed when negotiating narrow entrances, but a turning circle of 12.3 metres aids the Land Rover to nip through town and along country lanes with equal composure. As for the motorway, you'll find it stable and very hushed in the cabin.
The calm inside the Discovery has a lot to do with what's under the bonnet in the shape of the engine line-up. Most buyers will choose the 2.0-litre 'Sd4' turbodiesel unit we're looking at here - this is the smallest diesel motor every fitted to this green oval model. Mind you, it packs a big punch courtesy of 500 Newton metres of torque that arrives at a mere 1500rpm. You never have to work it hard and there's always enough oomph for overtaking, towing or cruising. Use its full potential and 0-62mph comes up in 8.0 seconds. As with all Discoverys in this range, an eight-speed automatic gearbox is fitted that assists with ease of driving and maximising efficiency.
Design and Build
Since the day it was launched, the Discovery has always had a unique look that's not just set it apart from its rivals, but also made it stand out from the other models in Land Rover's line-up. This fifth generation design moves much closer to the rest of the range and shares much of its inspiration with its smaller Sport sister. Good or bad move on the company's part? That's up to you to decide, but at least there are some of the classic Discovery cues in evidence - the rear C-pillar and the stepped roof for instance.
Once installed in the driver's chair, you have a commanding view of the road ahead and to the sides thanks to the elevation and large glass area. The main instrument display directly in front of the driver consists of an analogue speedo on the left and rev counter over on the right-hand side. Both are simple and clear, while in the centre is a digital display for fuel level and water temperature. Anything this can't tell you will be found on the centre-dash 'InControl Touch' colour touchscreen.
As for the rear of the car, there's plenty of space in the second row - and adult-sized room in the fold-out third row seats too - which is unusual, even with large larger 7-seat SUVs. As for luggage space, well there's lots of it - up to 1,137-litres with the first two seating rows in place, or up to 2,406-litres with just the front seats in use.
Market and Model
The Discovery may have steadily become plusher with every successive generation, but Land Rover still pitches its prices that little bit below most of its key rivals. As a result, you'll need around £48,000 to drive away in an entry-level model with the 2.0-litre 'Sd4' turbodiesel engine. As with every model in this fifth generation range, that includes an eight-speed automatic gearbox and full-time four-wheel drive, as well as the dirt-defying 'Terrain Response' system.
As for equipment across the range, well even the base 'S' model gets you 19-inch 'five split-spoke' design alloy wheels, halogen headlights with daytime running lamps, a heated windscreen and door mirrors with integrated puddle lights. The 'Brunel' front grille has a 'Narvik Black' plastic surround and there's more of the same for the wing vents and lower bumper sections. At the rear, a 'Powered Tailgate' takes the effort of out of opening the boot and there's also a 'powered Inner Tailgate' panel that drops down to make loading larger items easy. Body-coloured door handles lift the exterior appeal, while inside there's cloth fabric on the seats and eight-way manual adjustment for the front pews. Every Discovery comes with seven seats as standard in a 2-3-2 layout.
Cost of Ownership
Land Rover has made huge strides in making its cars more efficient and cheaper to run for its owners. At the heart of this push is a switch to an aluminium construction for this fifth generation Discovery. It saves 450 kilograms compared to the old model and, if you want to know how much that is, it's the equivalent of five rugby-playing passengers being removed from the weight of the car. As a result, it means this Mk5 model can now be offered with the 2.0-litre 'Sd4' turbodiesel engine we've been looking at here, a unit that offers up to 33.6mpg combined consumption and 197g/km of carbon dioxide emissions. Now, those figures are not quite as good as some in this sector, but you should bear in mind this British SUV comes with seven seats, an eight-speed automatic gearbox and full-time all-wheel drive as standard.
Every model has 'Stop-Start' that automatically turns off the engine when the car is sat still in traffic. As soon as you release the brake pedal to press on the accelerator, the engine fires up ready for the off. The diesel-fuelled versions use 'AdBlue' to lessen the impact of the tailpipe gases. This works by injecting a urea-based solution into the hot exhaust that turns the harmful chemicals into water. You can top up this solution's tank yourself or any Land Rover dealer will fill it for you when required around every 9000 miles.
Is the Land Rover Discovery the ultimate large SUV? For many, the answer was already a resounding "yes" and we'd have to agree it's a tough act to better. The world just seems a better place when you're sat up in its commanding driver's seat. Whether you're heading to the shops, on the school run or a skiing holiday, this four by four does the lot with a relaxed ease that makes most rivals seem well behind the curve. Of course, it helps that Land Rover has made this fifth generation model lighter and even more packed with driver aids. Plus it's easier on running costs in this four cylinder Sd4 form.
In summary, the Discovery is one of the most sophisticated, connected and just plain brilliant full-size SUVs you can choose. Noting quite matches the classless way it goes about its business.
As ever, the Land Rover Discovery is the most practical and capable large SUV you could choose. Now the opposition has even more to fret about, courtesy of improvements to this fifth generation model. Jonathan Crouch reports
Ten Second Review
There's nothing quite like a Land Rover Discovery and the improved version of this fifth generation model continues to offer the toughest, the most practical and the most capable choice in the large SUV sector. Enhancements include a smarter look, the adoption of MHEV mild hybrid engine technology and a much higher standard of media connectivity from the revised cabin. Yet the Discovery remains a supremely practical choice for up to seven adults and is an easy class-leader off the beaten track. In the large family SUV segment, there's nothing quite like it.
Without the Discovery model line, it's doubtful whether the Land Rover brand would even exist today. Launched back in 1989, the original version merely bolted more spacious bodywork onto an aging Range Rover chassis, but the sales it generated were enough to save the company. They also financed a more sophisticated five cylinder air suspended model in 1998 at the same time as the company's engineers were busily beavering away at something much better, third generation Discovery3 of 2004 which was ultimately developed into the Discovery4 of 2009.
It took a further eight years before this more unusually-styled fifth generation model arrived, a car now thoroughly enhanced with JLR's latest MHEV electrified engine tech and media features. Potentially then, lots to look forward to.
There's still something very special about a place behind the wheel of a Discovery. In contrast to more car-like rivals, it's not a cockpit-like experience with all the controls angled towards you as they would be in, say a Range Rover Sport. No, this is different - a place of command: a place to do business with the elements, be they the snake-infested swamps of the rainy season in the Serengeti or the snarled-up traffic of a wet windy morning on the school run.
This improved version of the fifth generation model gets a more capable Intelligent All-Wheel Drive system and Jaguar Land Rover's latest engine tech, all the units paired with a smooth and responsive ZF eight-speed automatic gearbox. Only the entry-level P300 four cylinder 300hp petrol variant does without electrified assistance. Otherwise, the brand's 48V MHEV mild hybrid tech features across the line-up's remaining three 3.0-litre six cylinder powerplants. Most will want one of the diesels, either the D250, which has 570Nm of torque and 249PS; or the D300, which offers 650Nm of torque and 300hp. There's also a six cylinder petrol variant, the P360, with 500Nm of torque and 360hp.
All variants get impressive towing capability, the diesel variants offering a class-leading 3,500kg braking towing total. Plus Land Rover has developed clever technology to make this towing ability more accessible. Advanced Tow Assist is an ingenious development which allows drivers to complete potentially difficult reversing manoeuvres when towing trailers, caravans and horseboxes with ease. As before, there's class-leading off road ability thanks to permanent 4WD and the standard 'Terrain Response' system. An optional Configurable Terrain Response set-up allows drivers to fine-tune the Discovery's throttle mapping, gearbox shift points, steering and suspension settings to suit their preferences and requirements.
Design and Build
All the usual Discovery styling cues remain firmly in evidence - the clamshell bonnet, the stepped roof and the highly visible C-pillar. Visual changes to this improved Discovery are subtle. The signature LED headlights create a more purposeful look, plus there are animated sweeping front and rear indicators and a body-colour front fender vent. There are smarter signature LED rear lights too, which are joined across the back of vehicle by a new Gloss Black panel. Customers can also make their Discovery more eye-catching with an optional 'R-Dynamic' pack, which brings a revised front bumper and more purposeful Gloss Black and Shadow Atlas exterior accents.
Inside, the key change is the adoption of JLR's latest 'Pivi Pro' centre-dash infotainment monitor with its bigger 11.4-inch full-HD touchscreen. This offers more immediate response, over-the-air updates, plus dual-SIM technology with LTE modems. It complements the 12.3-inch Interactive Driver Display digital instrument cluster screen, which can include a high-definition 3D navigation mapping. The steering wheel and gear selector have been re-styled too.
The second row seats have been redesigned with longer, thicker cushions, better lateral support and careful seat profiling. But the fold-out third row chairs are no more comfortable than before. We like the Discovery's stadium seating configuration, which sees each row of seats positioned higher than the one in front, ensuring every seat is the best seat in the house. Unlike some of this car's 7-seat SUV rivals, the third row chairs are designed for adults as well as kids. Auto Access Height technology reduces the ride-height by up to 40mm as passengers prepare to enter or exit the vehicle. You can specify a gesture-controlled powered inner tailgate and even with all three seating rows upright, there's still 258-litres of luggage space. With the first two seating rows in place, there's 1,137-litres of room. With everything folded, that rises to 2,391-litres.
Market and Model
Prices start at around £52,000; that's for the base D250 diesel variant. You'll need around £4,000 more to graduate up to the gutsier D300. The base P300 petrol version costs around £53,000. There are three trim levels; 'S', 'R-Dynamic S' and 'R-Dynamic SE' and pricing rises up to around £65,000. There's also a Discovery Commercial van variant.
A key standard equipment feature across the range is the 'Pivi Pro' infotainment system. And you're going to want to look at options like the 'Activity Key', a wristband that allows you to dispense with the usual key for when you're engaged in lifestyle country activities. Other key extras include a cabin ioniser, a head-up display and a gesture-controlled tailgate. There are various optional Meridian sound systems. And we'd also want Land Rover's Click and Go tablet holders, incorporated into the front seatbacks. The easy-to-use system also includes USB-A charging sockets that are perfectly located to minimise trailing wires. Using the onboard 4G Wi-Fi hotspot, which is capable of linking up to eight devices, rear passengers can be entertained on even the longest journeys. You should also consider the upgraded 'Terrain Response 2' driving modes system, which adds extra drive modes and a set-and-forget 'auto' setting.
Cost of Ownership
It would be wrong to say that the MHEV mild hybrid engine tech has transformed this Discovery's running costs because it hasn't, but it's made a useful difference and has kept efficiency competitive. MHEV tech is based around use of a Belt integrated Starter Generator in the engine bay to harvest energy usually lost under deceleration, which is then stored in a 48V lithium-ion battery located beneath the rear load space. It's able to redeploy the stored energy to assist the engine under acceleration, while also delivering a more refined and responsive stop/start system.
Let's get to the WLTP figures, starting with the diesels. Both the D250 and the D300 manage 33.5mpg on the combined cycle and 221g/km of CO2. It's a different story with the conventional P300 four cylinder petrol variant of course - 25.0mpg and 255g/km of CO2. Even the faster six cylinder P360 petrol variant does better (thanks to its MHEV tech), managing 26.4mpg and 241g/km.
Of course, the driver will need to play his or her part in pursuit of cleanliness and frugality, selecting the 'Terrain Response' system's 'ECO' mode as often as possible and keeping an eye on the 'Eco Data' part of the infotainment screen. Here, you get various screen options. There's one that shows you the 'Energy Impact' of various electrical items. And another with so-called 'Eco Tips' that are supposed to improve your frugality. More useful is the 'Driving Style' display that marks your driving efficiency from 1 to 5 in three areas - 'acceleration', 'speed and engine' and 'braking' and gives you a percentage-based 'Driving Score' as a result. There's also a 'History' screen that graphically shows your recent efforts at frugality, awarding you a little trophy for your most economical journey.
The world takes on a different appearance from behind the wheel of a Land Rover Discovery. At the helm, you know you're in a car that can take on just about anything, be that a seven-up trip to the Alps or a relaxing ride home on a wet and slippery winter's night. But it's only when you put it through its paces in properly extreme terrain that the genius in its design becomes fully apparent. How can a car capable of such extremes on the rough stuff be so utterly easy to use on the school run? Only Land Rover knows.
The more sophisticated design and clever in-car connectivity improvements of the enhanced version of this fifth generation model are welcome but ultimately, the recipe is as before. There's a clever, classless feel about this car that nothing else can quite replicate. Other rival SUVs claim to be tough but at the wheel, you're always a little hesitant to see them prove that. A Discovery's different, a uniquely capable SUV and a British success story that we should be proud of.
