Sources have suggested to Flat-6 News that Porsche is developing a turbocharged, all-aluminium 2.5 litre flat-four engine for use in the Boxster (pictured) and Cayman. Porsche has told Autocar UK that it is indeed working on a flat-four, that the engine is still in an early development phase and that it isn’t due before 2016.
Flat-6 News reports that the all-aluminium unit will likely be based on the Porsche Carrera S‘ 3.8 litre flat-six, but with two fewer cylinders. The engine will feature direct injection and VarioCam Plus, is expected to redline at 7,500 rpm and should be good for more than 350 hp and 487 Nm of twist – that’s 25 hp and 117 Nm more than the S variants’ 3.4 litre lump makes.
Porsche’s seven-speed PDK ‘box should benefit from reprogrammed algorithms to better exploit all that low-end torque, while a six-speed manual is still under consideration, according to the online publication. The new engine should make its debut in the third-gen Boxster facelift and second-gen Cayman, which will go on sale in 2016.

The Boxster is cantiq and cheap in price. Should have seen more on our roads.
And it’ll probably be named as Boxster Turbo and Cayman Turbo respectively. The whole family of Porsche will have turbo on their names at last. Cayenne Turbo, Panamera Turbo and 911 Turbo.
But I think if the flat-four turbo is the only engine offered in Boxster and Cayman, still will be called without the ‘Turbo’ badge. Unless the flat-four turbo is optional.
Car engine’s noise is getting worse year by year. The last best sounding supercar probably the Lamborghini Aventador and Lexus LFA
They are both NA (add Ferrari’s V12 into the list). It is no running from the fact that Turbo’s dull up the sound, Thu Bugatti Veyron and GTR is a prime example, they don’t sound like cars of their power.And I know that the Turbo V12 in the Huayra sounds great, but next to the 7.2l awesomeness of the Zonda it is nothing. Bernie Ecclestone is even considering artificial sound for next year Turbo V6. Though there are few exception, there’s no mistaking Subaru’s flat 4 Turbo burbble for anything else.
Indeed, turbo car doesn’t sound quite nice. For example, Golf GTi is faster than the Civic type R but the sound of Honda’s K20A is the best sounding 4 cylinder till now. Nissan GT-R is a fast car but sounds like a prawn. LaFerrari is still a N/A which can expect something from them.
To make Turbo sound better is to change to a bigger pipe and install a blow off valve which result a high pitched sound during gear shifting. But majority will complain the Ah Beng Boy Racer-ish image.
Luckily the upcoming Honda NSX and Lexus LF-LC still a NA engine, which can have some hope as two of them expert in high-revving NA engine.
GT-R is still faster
dafuq 4 cylinder turbo? why?
Yes NA engine sounds nice. Turbo car sounds, it will only sounds nice if you put external wastegate and if got anti lag device, even better. Now that will be one scary sounds when you go cucuk someone and will sure give some ah pek in camry or honda a heart attach when you overtake them and change gear.
The shocking face they get is priceless and i love doing that. Best incident was harley davidson rider….he almost lost control of his bike thinking his sound damn glorious till i antilag kow kow him when i overtake him. Priceless.
Antilag system = Misfiring system? What engine u using?
I guess you’re a kind of driver who uses turbo mainly because of its sound, right? LOL turbo cars with wastegate sound are sooo 1980s. When current manufacturer uses high-tech turbo engine that squeezes power from small displacement without those annoying wastegate sound, you’re still stuck in that era where the wastegate sound is something to be proud of. Move on.
