Porsche 911 Carrera S versus Jaguar F-Type R - twin test

But first things first: how do you spot a new turbocharged 911? Porsche’s design changes are predictably subtle. If you’ve clocked the massaged front valance and enlarged cooling ducts (which now have active aerodynamic shutters for on-demand cooling), then give yourself a gold star. I certainly didn’t.

At the rear, the differentiation is slightly easier to spot. There’s a new, more retro-looking air intake screen, a wider pop-up spoiler and new air outlets for the twin intercoolers just aft of the rear wheels. Otherwise, the Porsche’s shape is classic 911: still fairly narrow and cabin-forwards by sporting standards, but nicely compact and curvaceous with it. It’s utterly distinctive, in other words – in spite of the effect of the car’s popularity on our familiarity with it.

An F-Type R Coupé strikes a very stark 
contrast indeed. The Jaguar’s bigger, squarer 
body volumes, greater width and more blistered forms offer less visual subtlety and more muscle. 
It is somehow less prepossessing than the 911 
and at much greater pains to be looked at. The 
long bonnet and fastback rear end pay homage 
to classic sports car design type, whereas the Porsche wilfully disregards it. What we have here are differing routes to the design of equally appealing machines. Two years ago you’d probably have given the Jaguar the edge as a simple object 
of desire, but now – for reasons I can’t quite put 
my finger on – I wouldn’t. Perhaps the 911 just 
ages more gracefully.

Two outstanding driving environments keep the contest close as we start to compare habitability. Although it’s the wider car, the F-Type’s interior may surprise a few people by having the more intimate, cockpit-like feel. Your hips, knees and elbows are in close proximity to the leathery padding of their immediate environs in the Jaguar and the driving position feels more recumbent than the Porsche’s. There’s more luxurious, grand touring ambience to the Jaguar’s cabin, and more styling flourish, too.

But the 911’s cabin isn’t without richness or sense of occasion, its high centre console putting the gear selector at a convenient height. Smooth leathers, solid plastics and attractive decorative trims conjure a lasting impression of quality and understated elegance. Among the material changes brought in with the facelift are a new, smaller-diameter steering wheel (still round, praise be, and feeling great in your hands) and a swish infotainment system with a larger display (which looks and operates much more like a modern smartphone does and is all the easier to use because of it).

And so, on those all-important one-up, scenic-route drives at the weekend, you’d most likely find the Jaguar the more pleasant place to be – just. The 
rest of the time, though, the Porsche’s occasional back seats and greater carrying capacity would make it the much more usable car. What’s more important? You tell me.

Then comes the moment when you start driving these cars back to back and comparing what you find – and the exact opposite of what you’re expecting actually happens. With all of that extra power and torque, you expect the Jaguar to pummel the Porsche on outright performance. Moreover, you expect the F-Type’s big supercharged V8 to drown out any subjective appeal left in the Porsche’s boxer engine. But 
nope – not even close.

Here comes surprise number one: the new 
911 Carrera S is a very fast sports car. That may 
not sound like a huge revelation, but before this car, Porsche had never made a ‘normal’ 911 (one without a Turbo or GT-series badge on its rump) capable of hitting 60mph from rest in less than 4.0sec. This one is, and by no small margin. A full road test on the car is to come, but we can reveal now that, equipped with a PDK transmission, Sport Chrono Plus and launch control, the new Carrera S took a scarcely believable 3.5sec to hit 60mph in our hands. 
It’s quicker than a 996-generation Turbo, then, 
and quicker even than a 997 GT3 RS. Believe it.

The mid-range torque of turbochargers is only one of many factors that explain the car’s big-hitting pace; excellent traction and a quite astoundingly good two-pedal gearbox are two 
of the others. The engine and transmission 
work together brilliantly when you ask for every drop of available acceleration, and while the 
turbos add urgency and flexibility to the power delivery at lower revs, they cost the car relatively little on its high-rev range. So in flat-out mode, 
the Carrera S just feels rapid, quick-shifting and super-keen to gallop on.

For all of its power and bellowing V8 noise, the F-Type R feels much heavier than the 911, and although it goes hard, it’s quite clearly not the match of the Porsche on outright pace, our timing gear clocking it at 4.4sec to 60mph at best. The 911’s thick wave of torque actually makes the Jaguar feel just a little bit peaky, making you wait until 3500rpm for its full portion of twist, whereas the Porsche delivers it below 2000rpm.

At times, traction limits the amount of power you can use in the F-Type. At other times, it’s Jaguar’s eight-speed automatic transmission, which doesn’t have the same shift speed or instinct for the perfect ratio as the Porsche’s seven-speed PDK. Either way, the Jaguar always seems to have a ready-made excuse for not quite keeping up with its German opposition.

You may not think it needs one, of course. What the F-Type R is brilliant at is bowling along at an arm’s length from full speed – at that easily maintained, big-distance-covering, seven-and-a-half-tenths kind of pace that feels brisk but still responsible on the road. As anti-social as it sounds at full throttle, the car’s V8 filters a more measured but still wonderfully sonorous warble into the cabin under part-throttle, with the active exhaust set to ‘naughty’ mode.

For that reason alone, it would make a broader spectrum of journeys feel special than the 911’s six-pot might, being in possession of that little bit more soul.

But that’s not to suggest that the Porsche flat six is humdrum or ordinary – not a bit of it. Even in the face of such bombastic competition, the new twin-turbo 3.0-litre engine retains most of the mechanical charisma for which 911s have become renowned. There’s no doubt that the exhaust note is missing some of the audible detail that long-time owners will be used to. That tappetty, spluttering idle is present but muffled; the fizzing chatter of the 
valve train is less obvious at high revs, too. And yet the powerplant still offers a much greater operating rev range than a directly comparable 
V6, greater mid-range balance and smoothness and – in spite of some barely detectable turbo lag 
at low crank speeds – remarkable responsiveness for a turbocharged engine.

Add to that greater performance and usability, plus the advantage enjoyed by the 911 on ride and handling sophistication over the F-Type, and you’re led inexorably to wonder not how much corruption and compromise turbocharging has already brought to the 911, but instead how much more it could endure and still be as good as untouchable within its niche. Because the Carrera S’s chassis is better than ever. It’s flatter-handling and more composed, retaining just enough compliance for a supple ride but laudable crispness in response to steering inputs and idiosyncratic trailing-throttle handling adjustability for those who go in search of such things. Put simply, it’s brilliant.

The changes made to the facelifted 911’s suspension range from new dampers, anti-roll bars and helper springs to retuned adaptive damping software. What matters here is that, feeling light on its feet, fluent but controlled over bumps and incisive and balanced through corners, the Carrera S is a chastening lesson to Jaguar about how a multi-talented, mature and well-rounded sports car and occasional GT really ought to conduct itself.

Where the Jaguar can feel stiff-legged and abrupt over a choppy surface, working hard to contain its mass and keep its driving wheels 
in assured contact with the road surface, the Porsche has greater compliance, more lateral 
grip and quicker and more precise handling reactions. Lighter, more incisive and more communicative steering makes it keener to turn in, while greater traction also makes it more confidence-inspiring as you accelerate out of corners. In meaningful terms, the Porsche outhandles the Jaguar without breaking much of a sweat and, moreover, has better control of body pitch than any of its predecessors
