About LinkBacksOK it'll be twin turbo and stroll on with over 400 bhp... but the 8 is dropped, which I think is a great idea.
I'm actually hoping that, one day.. a 4 pot will resurface..
but until then, some weight lost over the front axle is a good plan.

There are only a handful of 4 pots I like, the 4G63, SR20, and K20s. All Japanese? Yes. Why? Because they've been at this game the longest and they play it well. Euro cars never had the PS limit Japan had so they were free to do as they pleased. The Japanese took it as an opportunity to screw the absolute most out of every component and of course, play weird games with the chassis and drivetrain.
One interesting story I herad was surrounding the use of skinny tires in some Japanese motorsports, that the trade off in grip is more than made up for in the shedding of unsprung weight as a proportion.
Nein nein nein! Straight 6, No V6's have ever touched anything with a rondal on!

Oops, sorry you're right. Don't know why I thought it had a V6. The original point still stands though.
the grip doesn't change, with skinny tyres, but the wear rate does so they have to choose harder compounds to last longer, which in turn reduces grip a tad.
and the tyre walls can flex more on some of the skinny ones.. but wet weather flexibility improves with that
back to the BMW thing... I seriosuly think a 4 pot might occur.
Has anyone seen the new AMG A class... it's a two litre 4 pot turbo.
mental effective engine. Waaay over 300 bhp.
Hmmm. I'd have to try it to form an opinion, but I worry that it might turn into a screamer. For me, an M3 is supposed to be smooth, subtle power delivery, not a jumped-up boy racer. Only driving one will tell me if it suits me.
Headline max bhp/torque figures really don't say how a car drives though does it.
My last car change went from 190bhp down to 150bhp, torque went up a bit.
But those figures are nothing compared to the character of a NA petrol V6 vs a turbo diesel 4 pot. Yeah the new car is fast enough, but I honestly don't think I will ever enjoy driving it they way I did the last one.
I don't know it that means I don't like turbos or in my old age I can't be fussed with 4 pot engines. I know I am not alone though.
The BMW V8 makes a glorious noise too.
Given that Formula 1 cars are going to be making the switch to four pot turbo'd lumps in the near future I think you might not be too far off in that assumption. They're certainly capable of dishing out high enough power and torque figures, leaving smooth delivery of that power as the only issue. Something I'm sure some clever turbo's and an apprpriate amount of computer skullduggery could make possible...
The Williams cars from the early 80's had V4, Quad turbo'd 1500cc motors... and still went like absolute sods.... Those Honda motors were something else.
Link? the next engine Renault are doing is a 1.6l v6

ok, so it's a V6, not a V4, and it's only got 2 turbos.... (damn that F1 history video lying to me) But it IS only 1500cc...

If that was a reply to me I'm talking about the new engines not the old onesok, so it's a V6, not a V4, and it's only got 2 turbos.... (damn that F1 history video lying to me

The new f1 engines were going to be turbo 4 pot, as requested by car manufacturers like Audi. But the likes of Ferrari argued against it, and the compromise is a V6.
It's a 1.6l V6, max 15000rpm, turbo with limited boost pressure but with electronic spin up assist and energy regeneration from waste turbine power:

I do like the electric turbo spin up & regeneration idea. So basically you can drive it like a supercharger? Wonder if a road car could use that as the alternator and get supercharging for free. I like supercharging, and I like free
I thought the V6 thing was because places like the US won't accept the idea of a 4 pot racing car. 4 pot seems ideal for a race car, it is just on the road where I like the lazyness of lots of cylinders. In fact the inherent out of balance nature of a V6 seems like a really poor fit for racing, why are they not allowed/given an inline or flat 6? Again, I presume that is a US centric thing.
Sort of. I believe it went something like:
Audi/toyota etc.: 4 pot would be more relevant to our road cars and if you have it we might enter F1
Ferrrari: We can't sell Ferrari's in the US with 4 pot engines, we don't want to waste that much money on F1 technologies we won't use in our road cars.
Audi/toyota: Actually we're not sure we can justify entering F1
Ferrari: F1 is Ferrari.
Everyone else: OK, 6 pot it is.
Spare exhaust turbine power as regeneration is already there on some supercars now, makes perfect sense. Electric spin up of turbo I think is part of some Ferraris, or they own the patent or something like that. It's a fairly obvious idea and I'd thought of it long before I heard anything about it from anywhere else, but obviously I'm not the only one! As for driving, yes supercharger in the sense that there's no turbo lag. More practically you can fix the boost at a set level so it's basically a more or less permanent fixed increase in power levels for the same capacity.
