And so the next chapter of Porsche 911-kind begins. Stuttgart has confirmed the worst-kept secret in motoring: the second-generation 991 will sprout a pair of turbochargers on lowly Carreras, boosting power and torque significantly and lowering emissions and fuel consumption.
This is downsizing in action. The new 2016 model year 991.2 will shrink the flat six to 3.0 litres in capacity, but swell outputs through forced induction. Key figures are:
# Porsche 911 Carrera 365bhp, 332lb ft from 1700-5000rpm, from £76,412
# Porsche 911 Carrera S 414bhp, 369lb ft from 1700-5000rpm, from £85,857
In both instances, that's 20 horses more than their predecessors. Both models share the same capacity; the Carrera S's extra power comes from modified turbos, a separate exhaust and tuned engine management.
This move for the first time in the Porsche 911's 52-year history to move the Carrera and Carrera S models to a turbocharged flat-six engine will be met with some degree of resistance among purist sports car enthusiasts, but the switch to forced induction has resulted in the fastest and most powerful Carrera and Carrera S models to date.
Four years after the arrival of the seventh-generation 911, codenamed 991, Porsche has overhauled the mainstream models with new engines, revised chassis settings, facelifted bodywork and a new infotainment system. The mid-life refresh is intended to keep the 991 competitive in the sports car marketplace until a new model arrives in 2018.
Both the Carrera and Carrera S use an all-new 3-litre, twin-turbocharged six-cylinder boxer engine. Both versions boast 20bhp increases over the outgoing normally aspirated models, with peak outputs now having risen to 365bhp and 414bhp respectively. The Carrera S's additional power can be attributed to its pair of turbochargers boosting at 1.1bar rather than the Carrera's 0.9bar. The turbochargers are fixed-vane items rather than the 911 Turbo's clever variable vane type.
Torque outputs have risen more substantially – by 44lb ft on each model – but peak torque is now available from just 1700rpm, right up to 5000rpm. For reference, the previous Carrera S delivered its peak torque at 5600rpm. The figures are 332lb ft and 369lb ft for each model.
With more power than ever the Carrera and Carrera S are faster than ever, too. With the PDK twin-clutch gearbox and Sport Chrono fitted the entry-level model will reach 62mph in 4.2 seconds – two tenths quicker than before – while the Carrera S also cuts two tenths from its 0-62mph dash to clock 3.9 seconds. Top speeds are now 183mph and 191mph.
Fuel consumption has been reduced by around 10 per cent across the board. Porsche claims a Carrera with PDK will now return 38.2mpg, with the S capable of 36.7mpg.
Straight line performance and fuel efficiency have benefited from the switch to turbocharging, then, but logic suggests that throttle response, exhaust note and top-end fireworks – between them the three factors that can make an engine memorable rather than just effective – will have taken a backwards step.
Q&A with Erhard Mossle, 911 product line director
What was behind the decision to switch to turbocharged engines?
'Our normally aspirated engine is famous, but we have the challenge of regulations on fuel consumption and also challenges from competitors. It's getting harder to get close to them with a normally aspirated engine."
Will buyers be happy with turbo engines?
'There will be some discussion over the next six months as customers try the car. It's similar to when we changed from the 993 to the 996, from air-cooled to water-cooled. Customers always look for the faster car, but we are satisfied with this package."
Is there more power to come from this engine?
'There is more power we can get; it is easier to get more power from a turbocharged engine than a normally aspirated engine. In the 911 GT3 RS, we had to go to 4.0 litres to get more power. We tried to model a normally aspirated engine and avoid turbo lag as much as possible,' he adds. 'A lot of detail work has gone into the system to improve response. For instance, when you come off the throttle the turbos keep spinning, so they are running at a higher speed when you get back on the throttle. We also have a new sports exhaust system that sounds really good. Yes, it's different to a normally aspirated engine, but it sounds better than the 911 Turbo, more emotional.'
Is there a place for the new four-cylinder engine family within the 911 range?
'I can't imagine a four-cylinder in the 911.

20 THINGS TO KNOW ABOUT THE NEW (TURBO) PORSCHE 911
SEP 7, 2015
1. It's turbocharged (but it's not called the 911 Turbo; that's a separate model). It's the first time in the 911's history that cooking models have used forced aspiration. It's a twin turbo set-up and the engine's all new. Still flat six, of course.
2. It revs! The red line is 7500rpm which is astonishing for a turbo.
3. The new engine is more powerful by 20hp. The new 3.0-litre churns out 370hp for the 911 Carrera and 420hp for the Carrera S. Not much, eh? But then the the extra torque...
4. It's torquier. Much. With 60Nm (that's 44ft lb) extra for both Carrera and Carrera S, the peaks are now 450Nm and 500Nm respectively. 911 flat sixes have always been torquey engines but now all that twist starts working from just 1750rpm.
5. It still sounds like a 911. They say. We believe them. Can you imagine the outcry if it didn't sound like a 911?
6. It's quicker than before. Every generation of 911 has been faster than the previous one and the new turbo range is no exception. 0-62mph time for a PDK Sport Chrono Carrera is 4.2secs (two tenths up on its predecessor) while the S just sneaks in under 4secs. No figures yet for the manual; yes there will still be a manual 'box.
7. Top speeds are up. The base Carrera is now a 183mph car, the S hits 191mph.
8. With the new rear-axle steering option on the Carrera S improving turn-in, the Nordschleife time is cut by 10 secs.
9. Going down... Every new Carrera automatically sinks by 10mm to improve high speed stability, a feature of the latest Porsche Active Suspension Management chassis. Porsche say it offers the best balance yet between everyday comfort and track driving performance, a balancing act that new dampers all round are said to help with too.
10. Going up... A new option is a hydraulic lift system in the front struts that raises the nose 40mm so you can negotiate pesky sleeping policemen and steep driveways without expensive graunching sounds.
11. Bigger rear wheels and tyres. Rears are up half an inch at 11.5 wide, wearing new 305 (instead of 295) rubber.
12. A tighter turning circle! Not an expected one this, and to be fair it still doesn't put the 911 in the London taxi class. But... a by-product of that rear axle steering option is 0.5m off the kerb to kerb distance, useful for those back street U-turns.
13. There's a new button: the Sport Response Button. Push this for a burst of max thrust for 20secs. It might be a bit like KERS but here there's no more power, just an early wake-up call to the engine management system, selection of optimum gear and 'pre-conditioning' of the drivetrain, whatever that means. You only get the button with the optional Sport Chrono pack though, which also gives you a new mode (normal, sport, sport plus and individual) switch on the steering wheel.
14. The 375mm diameter steering wheel (360mm for sport option) is based on the design of the wheel in the 918 Spyder hybrid.
15. Smart-phone style multi-touch gestures and handwriting input are now possible for the revamped infotainment system; smart phones can now be connected by Wi-Fi and Bluetooth (and there's a new tray in the centre armrest for your phone to go in!).
16. It still looks like a 911. This is a just a design freshen up, not a new body though there is a new look front and back with new lights... and we approve of the new black vertical slates on the engine cover.
17. It's available in the UK from December.
18. It costs from £76,412, with the Carrera S from £85,857.
19. Included are leather, sports seats, satnav and touch screen, universal audio interface, Porsche Active Suspension Management and a driving course at Silverstone.
20. Did we mention efficiency? Here's the main reason of course for the turbo turnaround. Porsche say the new model is almost 12 per cent more efficient than before, with the 911 Carrera with PDK returning 38.2mpg (and for the tax conscious, 169g/km of CO2) on the combined cycle. That's 3.8mpg better than before.
