2015 Nissan GT-R Premium vs Porsche 911 Turbo

By C. Dupriez

“The supercar for anyone, anytime, anywhere,” was the tagline at the Nissan GT-R’s launch in 2007 as it bid to dethrone the stalwart Porsche 911 Turbo from its lowly perch of unofficial “super sportscar”.

Where heroic stats and stopwatches were concerned, it could, though the GT-R just wasn’t that nice, refined or luxurious once the red mist subsided. It was a beast, and acted as much even going to the supermarket. Nissan knew it, and spent six years making GT-R more palatable and more potent – even the base version nowadays is called the ‘Premium’.

Thing is, Nissan has been massaging essentially the same old car – a car originally benchmarked a decade ago against the previous 996 generation Porsche 911. By the GT-R’s 2007 arrival, Stuttgart had its 997 generation, the Turbo version, as much as any other 911, moving the luxury-performance goalposts markedly. Then in 2012, an all-new, completely revamped 991 911 series arrived, moving Nissan’s aim yet again.

Eight years on, the now-ageing GT-R remains the challenger, the now fresh-faced Turbo still the guy to beat. And it seems the collective torchbearers for both may never come to a consensus in the long-standing row where the Nissan camp claims the bang-for-cash victory while Porsche protagonists maintain theirs is the ultimate luxury super sportscar.

Enter the current Nissan GT-R Premium Edition and 991 Porsche 911 Turbo. And Nissan claims higher ground as the most powerful and quickest accelerating of this pair.

But which is fitter and finer across the broad super grand touring experience, on road, the way most owners will likely use them? Doing so shakes out the real-world pace, driving enjoyment and liveability, be it around town or bombing across the countryside, their sizeable price disparity withstanding or not.

 

PRICING

In the past six years, GT-R pricing has risen. While the base version could be ordered back in 2009 for $148,800, today’s ‘entry-level’ Premium variant, as tested here, wants for $172,000 – some $19,200 pricier than six years ago when the Premium version was top dog. It is, though, $5000 cheaper than the Premium Luxury version (which adds red or ivory leather) and the top-spec Black Edition, which wants for $182,500. That’s a small fortune in most books.

Double the GT-R’s price and you’ll still come up short in meeting the ‘base’ 911 Turbo’s $366,500 asking price. That’s before you add its $22,145 worth of as-tested options that includes Sport Chrono Package ($9680), sunroof ($4990), black wheel paint ($1690), black painted wing mirrors and headlight elements ($1405) and digital radio ($1090). Call it $388,645.

But that’s not all the Turbo you can buy: the top-rung Turbo S coupe starts from $444,500. On paper, at least, you can’t get into any 911 for GT-R money. Cayman GTS is the closest Porsche cross-shop on price.

Regardless of pricing considerations they’re fairly well matched on twin-turbocharged six format and potency, all-wheel-drive motivation, full-fruit equipment levels and, well, approximate performance.

 

ENGINE AND POWERTRAIN

We say approximate because while the Turbo’s headlining claim is 0-100km/h in 3.4 seconds (dropping to 3.2sec if you’ve ticked the Sport Chrono option box and activated Sport Plus drive mode), the GT-R counters with a frankly ludicrous 2.7-second claim.

While the base Turbo’s 3.8-litre flat six’s tune is 383kW (6000-6500rpm) and 660Nm (1950-5000rpm), its Sport Chrono’s extra 50Nm ‘overboost’ and added launch control smarts milking that extra two-tenths.

When it first launched in Oz in 2009 boasting 357kW/588Nm, Nissan’s relentless massaging of the GT-R’s hand-built twin-turbocharged 3.8-litre V6 today presents a Porsche-crushing 404kW (6400rpm). The caveat is that, at 628Nm coming on at a high 3200-5800rpm band, it doesn’t have, on paper, the Turbo’s torque or spread. So far advantage Nissan.

The Japanese car’s powertrain has also evolved, less in hardware, more in tuning. It channels torque via a transaxle-style six-speed dual-clutch transmission and an adaptive all-wheel-drive system, backed by a suite of track-friendly differentials, an ageing if military-spec driveline capable of contending with engineers’ unquenchable thirst for engine outputs.

The overseer is its Advanced Dynamics Vehicle Control, allowing driver-switchable Normal and R-Mode drive modes suite or individual control of engine, driveline and driver enhancement systems to alter the car’s character. Neat tricks include ‘preselect’ gear change and rev-matching functionality together with launch control.

The Stuggart manufacture vehicle uses a seven-speed dual-clutch design together with a dizzying array of software and hardware features to enhance drive and handling. For instance, traction management (PTM) uses a multi-plate clutch plus two electronic systems (auto-braking, anti-slip regulation) to feed torque to the front axle from a permanent rear-driven state. And that’s apart, if linked to, the stability management system (PSM), dynamic chassis control, rear steering system and rear-axle torque-vectoring smarts conspiring to get you through a corner.

This might seem boring and rudimentary, but this is where you’re justifying the significant gap in investment demanded for the Porsche, with its fresher and arguably more advanced and refined package. Investment in the capabilities to bend physics to degrees that may make you laugh aloud in amazement once you climb in and give either a fair shake on the right backroads.

 

URBAN AND HIGHWAY DRIVING

The Nissan isn’t happy, though it is happier than versions past. Its softest-of-three Comfort damper mode remains utterly sporty and firm by other carmakers’ measures, it’s generally jiggly in ride and it thuds and jolts over square-edged road imperfections. It adds animation to mundane driving, its steering tugging off-centre as it negotiates old road surface tyre indentations. That’s despite changes in its bespoke Dunlop SP Sport Maxx GT600 run-flat tyre spec in 2014 aimed at improving ride and stability.

The seating height in the Nissan is moderately low, the leather reasonably supple, their shape less contoured as they are puffy. Given the whole instrument cluster moves with wheel adjustment, it’s easy to get comfy.

You don’t so much ‘climb’ as ‘fall’ into the Porsche, but once inside it’s, well, heaven. It takes little adjustment to find what so many describe as the 911’s renowned ‘perfect’ driving position, all controls falling superbly to hand, maximum comfort measured by unmatchable support everywhere a driver needs it. Though the thrum of the wickedly fat tyres is ever-present, the default ride of its adaptive damper system is sporting, though amazingly compliant given how instantly connected with the road the driver becomes. The all-wheel steering, too, creates a much tighter turning circle than that of the Nissan, and unlike the relative isolation of the GT-R steering, it seems like you can feel vibrations of every small rock transmitted up through the Porsche’s direction finder.

Both are effortlessly swift on their feet when on a roll, neither requiring much more than 2000-3000rpm in normal cruising duties. Even with a bit of urban driving mixed in, both returned fuel consumption figures in the mid-10 litres per 100kms – numbers not far off their makers’ claims.

But it’s the fatter and flatter torque curve that makes the Porsche easier to correspond with road speed with your right foot. The GT-R, which, like the 911, wants to climb to the top gearbox ratio quickly to achieve best-case fuel consumption, is a bit peakier in engine delivery, having a tendency to lunge with much more than a right foot squeeze.

The Porsche’s PDK transmission couldn’t be more different than the Nissan’s gearbox and driveline. The 911’s up and downshifting with glassy smoothness at any speed, arguably makes it the most refined dual-clutch design out there.

 

COUNTRY ROAD DRIVING

Put your foot down and both sports-cars will arrive anywhere faster than you can think of the destination, though the GT-R needs to be in the mood – R-Mode drive setting. It primes the powertrain – ups the revs, sharpens the throttle, and sets the gearbox to ‘shoot-to-kill’ – such that every twitch of the right foot creates an explosion of acceleration. Conversely, in Normal drive mode there’s a pause before the action, exacerbated by a gearbox that shuffles sequentially from where it’s been to where it actually wants to be slower than you’d ideally want.

The Porsche is thriftier getting a move on in Normal or Sport, adapting to the driver’s whim with less fuss. But in Sport or over-boosted Sport Plus, like the GT-R, the amount of sheer thrust with about 3000-4000rpm on board is breath-taking.

From A to B along a narrow back-road, patches of overnight rain randomly changing grip levels, I can’t imagine swifter devices than this pair. Not even the 911 Turbo S, and for a very important reason. Even at a spirited clip, you rarely harness all the power they deliver. Bar momentary full-throttle plunges exiting tighter corners, neither requires much more than half throttle to be driven quicker than is prudent anywhere other than a racetrack. You’ll be teasing the limits of grip; amply flexing chassis muscles and have their electronic driver aids working overtime.

Push bot harder and, ultimately, the Turbo is the better performer. In measures of pace, it plies its energy to the road more effectively. It’s not simply the torque advantage out of corners, but how its adaptive dynamics package seems more pre-emptive and precise in shuffling torque between all fours than those of the more reactive GT-R.

The Nissan is more animated in corners, wiggling more over bumps, relinquishing tyre grip more suddenly, demanding more driver input to track a line and more correction keeping a true path. If you’ve got the driving skills, it’s an absolute joy to drive; up until the point when that Porsche Turbo ahead of you disappears into the distance.

It becomes clear quite quickly that there’s more to the Turbo’s bag of tricks than mere sheer grip. The Porsche is more low strung, feels to have a lower centre of gravity, and sits incredible flat to the road despite allowing the wheels to travel further in the suspension stroke.

The GT-R felt big, heavy and sketchy throughout the mixed conditions that hampered much of the test. You have to handle with care a little bit; as the front end isn’t as keen to turn in, and the rear end is a little too keen to step out, compared with the Porsche.

The Porsche on the other hand couldn’t be more different. It just takes agility to another level – the four-wheel steering, torque vectoring and stability systems work seamlessly to get all of the power necessary to the ground. The Turbo never feels heavy, unhappy or even remotely bothered with any driving task you throw at it. It’s always compliant, composed, forgiving and, importantly for when you want it to be, fast.”

The GT-R steering, while direct, drew criticism in the company of the sublimely intimate and engaging Porsche system. “Distant” was the word used to sum it up. It also seems that in cool and damp condition, both the Nissan’s brakes and tyres never seem to feel like they’re working quite as sweetly and confidently as they should. At once, the huge gold-coloured brake callipers seemed to lack bite and the kind of progression that demands reasonable foot pressure to reward with accuracy.

Because the Porsche is friendlier, it doesn’t demand the driver reflexes that the GT-R does. It can be enjoyed at high speeds by moderately skilled owners, not merely because it’s incredibly planted and hugs the tarmac over rough or smooth surface, but because it’s so engaging to drive. Both the steering feedback and front-end grip – at least on poor open roads – is markedly better than the Nissan’s, so you can arrive into corners with more bravado and be confident it’s batting more faithfully for your side once you do.

 

EQUIPMENT & FEATURES

The 911’s cabin is a lovely place to be. Its design, button-laden centre console apart, is classic Porsche: clean, logical and superbly crafted. But then again, it’s not appreciably more premium than a Boxster at a third of the price, nor any more special than a base 911 Carrera. And while it’s refreshingly free of superfluous excess, charging extra for a reversing camera in a $366,500 sportscar is, frankly, ludicrous by any measure.

The GT-R throws a variety of materials and features at its cabin to find its upmarket groove, though not much has been changed in eight years and it’s starting to feel outdated and out-of-touch. Nissan or not, it’s just not good enough for $172,000. What it lacks in bona-fide premium feel, though, it makes up for with its whiz-bang Multi-Function Display telemetry system that provides race car-like real-time diagnostics.

Both cars have shortcomings in interfacing their transmissions. The Turbo has handy wheel-mounted paddle-shifters that allow gear changes in any situation but, surprisingly, persists with orienting its console shifter so that forward is for upshifts rather than adhering to the intuitive motorsport convention of back for upshifts. The GT-R, in contrast, mounts its paddle shifters on the steering column rather than wheel, hampering gear changes when there’s any amount of steering lock on, thus limiting one major benefit of the twin-clutch design.

 

OWNERSHIP

Both cars come with a three-year warranty, though the GT-R’s is capped at 100,000 kilometres. Porsche has a service schedule of 12 months or 15,000km, whichever comes first, that extends for eight years.

 

VERDICT

The reality of the situation and I think everyone who’s ever driven both cars will agree with is that GT-R demands a circuit or racetrack to display its stripes more convincingly. On a dry racetrack with higher temperatures and a greater margin for error, the GT-R could confidently take it to the Porsche. But I guarantee it would still take vast amounts more effort and concentration than would be required to achieve the same pace out of the Porsche.

And it’s that almost singular performance focus that has long been the very thing that has presented the Nissan with compromised levels of liveability, comfort and refinement – areas the GT-R still struggles to fully deliver.

By attempting to encompass everything from premium luxury to racetrack heroism in three variants separated by little more than seat and wheel trim, the GT-R feels a bit more jack of all trades and a master of none.

In offering some 25 different variants – yes 25 – Porsche offers a 911 for all occasions, each targeting a niche with consummate precision. And the Turbo leaves the endearing impression that it has been engineered and tuned as the finest super grand tourer without compromise.

The only area the GT-R trumps the Turbo, is on value for money. Not only is this current-generation beast-of-a-car unchallenged for performance for its price, driven in isolation its all-round super grand touring credentials are hugely impressive. But the presence of the fresher and fitter Turbo makes the Nissan feel a little outdated.

Yes, the Turbo is wildly expensive. Yes, you could land both a GT-R and some other properly premium grand tourer in the garage for Turbo money. But you do climb out of the Porsche wondering where you could possibly improve it. And wonder why you’d ever pay the extra for a Turbo S.

One thing remains unchanged in all of this: the Nissan GT-R is still the challenger to the ‘king’ of the super GT crown that the Porsche 911 Turbo continues to defend.
