We like: Effortlessly muscular, a smart alternate to more prestigious VW Group models.

We don't like: Emissions count, no third row seating, awkwardly-site front cupholders.

AROUND $60 billion to spend on increasing the count and production of electric cars and batteries … within the next four years.

You could say Volkswagen Group is spending as if there’s no tomorrow … and, in a way, that’s exactly why they’re doing it. That the ‘tomorrows’ for orthodox fossil fuelled vehicles are running out is recognised as being a cold, hard fact.

VW isn’t hanging around for the end of that world as we know it before concocting a Plan B. It’s blasting off to Planet Electric now. There’ll be 70 all-electric VW Group models by 2030, of which 20 are already signed off, and around 60 hybrid models by then as well, of which just over half are already being built.

The volume ambitions are massive: 26 million fully electric models built this decade; 19 million based on the MEB (basically, mainstream electric) platform that underpins the NZ-bound Skoda Enyaq, Audi Q4, VW ID.4 crossovers, the remainder utilising a high-performance PPE (for ‘premium platform electric’) underpinning, which has yet to be used. That one is designed for vehicles of medium size or larger and is suited to both low- and high-riding applications.

Their rush has been fuelled by Dieselgate. VW’s unfortunate incident has utterly reshaped Europe’s biggest car maker and hastened the death of diesel.

Or so the headlines might have you believe. In fact, as much as VW is keen to move on from a period of significant unpleasantness – and despite the fuel type falling fast out of favour in key markets close to VW’s homeland - it has yet to quit a dirty habit.

Look at the make’s pitches into the markets two core sectors, utes and large sports utilities, and you’d have to conclude diesel is far from dead. Quite the contrary.

Still, that’s going to change. A platform-sharing project with Ford in which the Blue Oval takes the lead role means the next generation of VW’s Amarok, coming in 2022, is set to be a ‘Ranger-rok’. The drivetrains remain a mystery, but Ford has said it wants to electrify its commercials. Hence why NZ will get a fully battery-enabled Transit as an option to the PHEV edition now incoming. Same for the traydeck?

Later this year, the big Touareg five-seater sports utility wagon will also take the plug-in plunge, becoming not only the first in this family to do so but also set to be the first large mainstream sub-$150,000 European vehicle here in that format.

The e-Hybrid variant is going to be high-profile. It represents as a member of the make’s R performance sub-brand and delivers with the same 250kW turbocharged 2.9-litre petrol V6 mated to a 100kW electric motor, fed by a 14.1kWh battery mounted beneath the boot floor, that has represented in the Porsche Cayenne E-Hybrid.

It’s a smart drivetrain: Up to 50kms’ electric-only running, plus emissions and economy that, just a decade ago, would have only been possible from a small car. Yet it’s a miser with serious muscle. Hence that R accreditation. Although VW says their package prioritises comfort and refinement over outright punch, it’ll be … well, electrifying. Expect the 0-100kmh sprint to take around five seconds and an electronically limited top speed of 250kmh.

So the Touareg R is a model to look forward to, the next big step into a future we cannot ignore, one that quite potentially will lead to an all-electric conclusion in time.

Still, it would be surprising if Touareg fans immediately warm to it. Not because electric isn’t ‘right’ so much as because diesel has done their vehicle of choice no wrong.

Of all VW’s SUV models, the Touareg has consistently been the most dedicated to diesel powertrains with proven plus points of low fuel consumption and running costs for higher kilometres-per-litre economy, effortless grunt and long range between refills.

Having a new compression-champ in the line is unlikely to make transition away from the dark side any easier.

The new 4.0-litre V8 that became available from late last year is potentially going to be viewed as the most obvious alternate to the electric newcomer, given it holds the same flagship status and is very likely set to be closest on price.

If comparison is to be made, however, it’s likely there will more differences than similarities in how they operate and what they deliver.

They come closest in respect to power, and even then there’s no parity; the PHEV generating 30kW more than the big-bore diesel. When it comes to torque, the diesel wins easily, with a third as much again.

VW has yet to present economy and emissions figures for the PHEV, but it’s fair to assume the counts Porsche has discussed will be a fair indication. In which case … well, it cleans up against every diesel. Comprehensively. Which of course, is the whole point. Even though it meets latest Euro 6 requirements, and rarely puts out any black smoke even at start-up, a rated count of – cough, cough – 258 grams per 100km means that, even with the smog unseen, the V8 counts as a smutty thing.

Still, while a black mark, it’s hardly a killer blow in our market, not least when our Government has yet to initiate any particular emissions legislation. It’s not the cleanest new diesel, but at same token it’s far from being the dirtiest vehicle on our roads. You only need to follow any school bus or any light truck imported used from Japan to be reminded of that.

The prospect of the V8 being subbed out once the Touareg R hits the playing field has never been voiced by VW here and I doubt it’ll happen, for good reason that the latter has become an immediate hit since launch.

To say that this engine has imprinted on the buyer base is an understatement. It’s quite possibly the ultimate black hearted hero of the moment.

The test car, at time of driving, the last of the First Edition models that comprised the initial shipment; every one of those was snapped up. Basically, all examples on the next boat were signed up when still at sea and there’s a growing waiting list.

The appeal is pretty obvious. Putting environmental concerns to one side, the spec of this twin-turbo engine is drool-inducingly impressive.

For one, it’s the most powerful Touareg engine ever; gruntier even than the first generation model’s flawed but fondly-remembered V10, developed at the behest of Ferdinand Piech to simultaneously elevate the diesel engine and the VW brand.

It’s come to this model with an illustrious heritage, having done time in the rich-lister Audi SQ7 and SQ8 and the Bentley Bentayga – where it took an electric supercharger. The lack of that latter element in the VW formula is no particular problem as it still emphatically from a different planet than the Touareg’s V6 that, in most powerful form, makes 100kW less power and 300Nm less torque.

Those who bought into the First Edition did well. With a Black Pack trim – literally that, with every exterior element in that colour (and most of the interior, too) – it’s a smart-looking car and a smart buy, too. The premium it held over the regular version covered the cost of a 48-volt active roll stabilisation system that’s a $7500 cost-extra in the regular model. In addition to this, the First Edition also received a superb Dynaudio sound system. That’s also a pricey item, so effectively it came for free in this case.

The engine is the big pull. Quite literally. The appeal reveals easily; it’s smooth, refined and massively powerful; put your foot down and, no matter what pace you happen to be holding, it just surges forward with huge and growing momentum. In typical diesel style, the oomph emerges in considerable force at rev levels at which any performance petrol would still be in doze mode. Even at a steady 100kmh, the thing is typically showing around 1800rpm on the dial. There are quite a few numbers between there and the redline that possibly will never be visited much at all, if ever. Because there’s no need.

Ok, so it’d be stretching to say it's not wholly free from lag, in spite of the efforts of its clever dual turbo set-up. There is still a momentary hesitation, but once that breath is taken, though, the load of seamless stonk is truly impressive and bodes well for off-roading and towing. Anyone who buys one of these and doesn’t use it to haul something significant is wasting a tonne (well, two and bit tonnes) of talent.

What’s a bit unnerving, initially at least, is that there’s not a lot of noise when it goes into lout mode, at least until you activate the performance mode. That seems to introduce extra aural fireworks. But it’s not necessarily a true-life soundtrack. I suspect it has an acoustic enhancer that uses the stereo speakers. Leave it in the standard drive mode, though, and it is pretty quiet.

Economy suffers when you push the limits, of course, but it’s nothing like as thirsty as any petrol. Volkswagen claims an optimal 9.9 litres per 100km is possible, but I wasn’t at all unhappy seeing an average of ‘only’ 10.8L/100km from a week-long stint in which the vehicle was employed in a wide variety of driving duties, even a touch of off-roading. Nothing particularly strenuous, of course.

Putting almost 500km on the clock accounted for less half a tank consumed; nothing to do with a poorly calibrated gauge. This version runs a 90-litre fuel tank. According to the drive computer, it will deliver at least 1100km of range on a single tank. So you could cruise all day.

About that. Cruising is what is does best, yet don’t estimate the talent: On occasion it feels even more agile to drive than the Audi Q7, which is supposedly the sportier model.

That active roll stabilisation system definitely has positive imprint on body roll, the air suspension that either firms or soften the ride, depending on what you want, is also a good thing and having 4Motion permanent four-wheel drive is an obvious plus. True, it’s not outright thrilling, but it does come across as a easily-controlled car, but not an outright dextrous one.

Of course, that’s all written in context of its sheer size. In pure physical terms, this generation of Touareg large enough to be hulking, so it’s a big thing to put down a country road.

In that scenario, the steering also still feels a bit too light and distant for true entertainment; it needs room stop, too. The PHEV should be better, but so it should, given the pedigree it’ll bring. R-Line is all well and good, but nothing should surpass a real R.

Saying it’s happiest on big, wide, sweeping roads is perhaps not a criticism. The ride quality is more decent than you’ll find from the Audi equivalent, for instance. And being more laidback suits the overall personality. The combo of refinement, sledgehammer thump, quality, comfort and space mean that it's a decent choice for long journeys, and a deeply pleasant thing into which to climb every day. But it's not as agile, nor flickable, nor engaging as it might be. Call it composed.

The exterior styling - big, square of shoulder and jaw, and with that massive radiator grille and piercing lights – is lasting well, but it's the interior that’s the Touareg’s strongest aspect.

Quality levels in this model are exceptionally high, and even if if the overall design and layout might seem a bit stark and grey – because, well, that’s just the VW way - it's nonetheless a very pleasant place in which to spend time.

If you had to pick one outstanding aspect, it's that it is very welcoming to occupants. Front seat occupants haul themselves into big front armchairs. Those behind also enjoy decent comfort and lots of leg and headroom. There's no seven-seat Touareg as yet, nor any sign of one on the horizon. Is that because VW doesn't want to pinch sales from the seven-seat Q7? Anyway, it does have a massive boot.

All Touaregs bring a huge amount of equipment to the table and all have the 15-inch touchscreen in the middle of the dash backed up by the 12.3-inch 'Active Info' display behind the wheel, which is your all-singing, all-dancing instrument panel.

The two displays are linked, although you can't slide, drag and drop items between them, but you can use the central display to setup the information that the instruments show you. You can also use it to adjust the seats, the stereo, the navigation, the climate control - virtually everything in fact. There are hardly any physical buttons. Yes, the system is a touch fiddly and thought-intensive at times, but it’s more logical than many.

The comfort, the car’s height and solidity, plus performance that feels brisk and muscular enough for almost any circumstance … well, there’s a lot going for this particular variant.

All in all, it very much reinforces that while diesel is slowly leaving the scene, it isn’t set to depart without reinforcing why it still has many merits.
