Porsche Cayman and Boxster Will Return To a Flat 6, Allowing the 718 Twins to Reach Further Audiences

Contrary to some opinions, Flat 6 engine, often associated with Porsche, is better than 4. But instead of the new 4.0 Flat 6 having a monopoly over the 718 chassis code, it will give the old 4 cylinder a second chance at a new life at the entry level.

Porsche’s decision to go to the flat 4 last time was probably a good idea at the time in terms of costs, fuel consumption, and packaging. However, they completely forgot about a few crucial conditions that Porsche owners pay attention to. Sound, and being proud of your engine.

The 4 cylinders were a marvel of engineering, no doubt. The power from the little motor was astonishing and the fuel economy didn’t suffer, but who wants to listen to that engine with the top down on the highway? The answer actually goes multiple ways. Let me explain.

Flat 6 Engine Is Returning

The return of the Flat Six Engine is going to be fantastic. The 3.0 liter flat 6 from the Carrera gets punched out to 4.0 liters, loses the turbos, and drops into the 718 Cayman/Boxster. Natural aspiration in a car like this is key to enthusiast. A pure driving experience can be tarnished by turbos in some cases as they make controlling revs difficult. The old, dishonorably discharged, flat 4 didn't have much turbo lag at all, but an NA motor will feel so much more engaging for a sports car.

The previous Porsche 718s get a bad rap with the general community, but the truth is inescapable. It’s a fantastic car. It drives like one of the best mid-engine chassis of all time. We can all take a rain check on that motor, however the design as a whole is something to be thankful for. And now that flat 4 will have its place as a base engine. Yes, the engine will have to stay for now but for good reason.

The 718 cars are likeable little sports cars, not just to enthusiasts but the general public. Someone who is in the market for a fun car may see the cheaper version of a great car and love it for what it is. This person may not care about having a 4.0 liter flat 6 with a six speed manual that can do 0-60 in 4.3 seconds. This person wants to enjoy a Sunday morning drive and go the speed limit.

Porsche had finally heard enough from the journalists who sent the old engine to automotive exile, so now the flat 6 is for the person who does care about all those little things.

Also, please, take a look at my yesterday's story about driving your Porsche 911 on loose surfaces and how it makes more sense.

I am happy to consider a Cayman 718 GTS with a flat 6 but only if I can have the PDK as I can no longer operate a clutch anymore.
Sadly the new 718 4.0 Caymans will be 6 speed only. However Lower trims will have autos.
I don’t understand the manual only mentality. No one buys a manual anymore unless it’s in the glove box.
Manufacturers do it mostly to make cars look more “special” or limited. a manual only car intrigues those enthusiasts that will give the car a good review.
In my view the manual only does not make sense. Would never go back to manual after the experience with the PDK in my 981 Boxster S, a fantastic car btw. So I‘d rather go for a 981 Boxster GTS in mint condition than the manual only Boxster 718 GTS. Alternatively, I would rather go for a 911 Targa straight away. A very nice car indeed. A shame really as otherwise it seems to be a fantastic car. On the other hand, it is so close to the 718 Spyder performance that I do not really see its place in the range of 718 options.
Supposedly a 6 cylinder boxer engine is quite a bit more balanced than a 4 cylinder boxer engine in terms of geometry. Always nice to see more cylinders, and not just turbos to make the power, and the 6's usually sound a lot more melodious as well.
Any insight on whether the flat six will make it to the base and S models?
Sadly, so far the base model and Cayman S are set to get the 2.5 flat 4. If there will be another engine option for those cars we haven’t seen it yet. Reason being that the cayman gt4 and gts 4.0 will get the 6 so they have to keep the 4 cylinder in atleast those two models.would be a big waste of money to use a while new engine for just 2 model years.
