This was posted today on Jalopnik and sounds like a 4 banger to me... Flat 4

turboed-4!
Sounds cool! Kind of similar to a Suby.

If I do the maths from the actual engine range and I remove 2 cylinders I take te same power ratio, I get theese numbers:
1804 cc from 175 to 185 hp (not likely)
1804 cc turbo up to 245 hp
2291 cc from 210 to 215 hp (not likely)
2291 cc turbo up to 335 hp
2533 cc up to 265 hp
2533 cc turbo from 345 to 375 hp

Up to 395HP?

I made my calculation based on power to cc ratio of the existing engines.
The 911S engine makes 560.
560 x 4/6 = 373 not 395
Reporters write what they want because they have no information about this engine at all.

Yep, sounds like a wrx engine....nice. So many rumors, I wonder what they are actually working on for this engine and the possible GT4 (same car?)

THis will make an owsome upgrade for 914 in 10-15 years ...

My thoughts exactly!

It doesn't matter how efficient that motor might be, I doubt very much if people will want that engine in a 911. Cayman and Boxter maybe but who wants a 4cyl 911?

Think they are thinking about 10 years from now Elliot.....If I read this right, emission cuts by law for the EU are difficult to make.
I don't know if Porsche are exempt from these in the US market though.

They need to have 4 cylinder engines in their range to comply with the new regulation. It may not sell very well but it is mandatory to lower average co2 on the range.
"The fleet average to be achieved by all new cars is 130 grams of CO2 per kilometre (g/km) by 2015 – with the target phased in from 2012 - and 95g/km by 2021, phased in from 2020".
This is also why they put a lot of hybrid models in their range. Hybridation also allows smaller and lighter petrol engines

Isn't that called a 912?
Posted by: johannes Aug 3 2014, 01:34 AM
Yes it was called a 912... will the new Cayman with four banger be called a 914 ? ... no

How about a K914?!

Unless Porsche purposely developed an unequal length exhaust, that doesn't sound like a four cylinder. The only reason a Suby sounds like a Suby is the weird exhaust port configuration. If you build an equal length header it still sounds like a regular four cylinder. Even Subaru has changed the new engines to a more equal length exhaust port and header configuration. They do not sound like the old engines.
I question the four cylinder observation. That sounds more like a V8 of some variety. It revs too slow to be a four cylinder and it has that much deeper tone of a V8.

A V8 would be a weird downsizing strategy ...

Could be some testing for this engine:

With DI and the new turbo technologies you can add about 25-50% to all of those numbers.
That being said.. That doesnt sound like anything i've heard under 2L. That engine has some displacement..

This motor is being developed for a new roadster that will be entry level car below the boxster. In about 3 years. And it will help them meet the emissions standards etc as mentioned. Some of the leaked mock ups put it in the realm of a 914 type vehicle and I think the price point is somewhere in the $40k range.

Boxter and Cayman fill the mid-engined catagory nicely. This needs to be in the all new 2016 Porsche 356

the rules changed when VW bought them.
Its the whole fleet now, and VW can do alot to ensure they comply....without having to touch Porsche.
The Diesel and hybrids are because the Cayanne gets lousy gas mileage.
Posted by: johannes Aug 6 2014, 09:16 AM
130g average in 2015 is impossible for Porsche alone. All cars are above 160 except the hybrid cars that are at 70g ... and everyone knows this is just a big joke because mesured on very short distances.
