Engine Sizes

As long as the BHP & Torque's rise, wheres the issue with the loss of engine size?

Its a shame to all us petrol heads, sure, I guess its progress.

V10's & 12's are going to very soon be a thing of the past.

As for the OP's Turbo or N/A question, I guess I'd have to say N/A despite only owning a few (2) turbo cars in the past out of the many many N/A, I'd imagine in the future, turbo's & superchargers are going to become far more of a norm.

I never thought I'd see the day my old man dropped a 6 pot for an inline 4 with a supercharger strapped to it! - progress indeed! :D
 
Must admit isn't F1 racing going from 2.4 litre V8's to 1.6 4 pot turbo's in 2013. They will also have a fuel limit restriction.

They will still produce over 600bhp+ Kers. Wonder how long it will be to filter down into your average Astra :D

Small 2 litre hot hatches are replaced by smaller 1.6 or 1.4 engines with turbos strapped to them to make up for the engines otherwise poor output.

RenaultSport Clio 172 - 2.0L

Renault have got it right :)

Looks like the new RenaultSport Clio is going to be a 1.6 turbo (Nissan engine) if the rumours are true. Hope not, I love mine and don't think it'll be the same with a turbo strapped to it!
 
My only thought on smaller engines is that by reducing the size and maintaining the power by supercharging and/or turbocharging, the amount of costly things to go wrong on the car increases. Long term this cant be good for repair costs. It might even wipe out the money saved from efficiency gains.
 
I would trust a Nissan 1.6 turbo to produce more power with reliability over any Renault built 2.0 litre engine. Not being funny but Renault has not exactly got a great reputation for reliability in the world. Nissan has proven itself to be pretty bullet proof over the years with the exception of their 1.5 timing chain issues. Lets face about 30 million Asians cant all be wrong. :D

You do realise that Renault and Nissan have been in an alliance for over 10 years now, resulting in Renault owning almost half of Nissan? There are now lots of platform sharing operations going on and many models of both Renault and Nissan which are mechanically the same in quite significant areas.
 
Take the new Nissan Juke - Jap car? It's built on the same platform as the Renault Clio. Previous generation Micra? Had a Renault engine in the lineup..

I always thought that Renault, Peugeot and Citroen developed the engines in partnership with each other. I am not saying you are wrong put I am not sure which engines and cars do Renault share with Nissan. At this time more likely Diesels.

I am only saying this as my ex-wife's family owned a garage and when Nissan parts were unavailable they tried to use Renault equivalents which where supposedly the same according to autodata but proved totally different. Things like hoses etc. In drawings and spec they should have been the same but were total different fitments. Things may have changed over the last couple of years but Nissan and Renault at that time were still very different entities.
 
Renault and PSA do not develop engines together, they do it themselves.

Renault and Nissan, as said above, share engines, platforms and other components quite heavily.

I was just pointing out that it was rather amusing to be so anti Renault but pro Nissan when the reality is that they are becoming two sides of the same coin..
 
I really dont understand what happened to the world.

In the late 80s we had the Turbo in regular cars (nissan bluebird Turbo), it was becoming a prominent technology. It was cheap, easy and for the displacement/poweroutput not particularly inefficient.

Then Suddenly come the late 90's the manufacturers thought, dang if we give everyone turbo cars, perhaps they will never want to buy another car again? So lets pretend the turbo is BAD and instead replace it with semi inefficient high reving low displacement high output engines.

So we went from having Celica, 200sx, Pulsar, Starlet, Vitz/Yaris, Escort, Fiat Coupe turbos to B18, B16, K20, 2ZZ-GE, SR20VE plus a raft of V6's such as the Nissan VQ35, Renault V6, Alfa V6 non turbos in what i can only imagine was some faux play to pretend higher MPG vehicles.

Except when used properly these engines are woefully inefficient.

SO quick about turn, lets drop all the V6 and go back to a 4... but with.. wait for it... a TURBO to give it the same power but better efficiency?!

How about instead of stopping development of turbo engines in models COMPLETELY in the late 90's and early 00's they had continued to just make more efficient turbos as the digital age was coming around giving them the access to electronics ti help make better controlled and less laggy outputs?!

So now, instead of a 2.0 High rev high output NA, we have a 1.6 Turbo. Instead of a 3 lite V6, we have a 2.0 (inline4) turbo.

But why?! What was the reason to Ditch the turbo instead of continuing its development?

But the kicker is this, they didnt actually stop developing turbos, they just kept them almost exclusively for Weasels, sorry i mean Diesel motors, as we saw the rise of the TurboD just as we saw the decline of the PetroD.

And it wasnt just 1 manufacturer who has done this. But i mean, look at Nissan, and Toyota as prime candidates as they really did have a great line up of turbo technology and then completely diteched it and still havent really recoevered to include Petrol Turbos into their new car line up.

But take Ford for example, after the Cossies and the RS Turbo escorts they went for a reasonable amount of time before they introduced the turbo back into the range proper. And it still hasnt filtered down to the fiesta, or filtered its was up to the Mondeo, which had to make do with one of those V6's i talked about instead of continuing development of those turbos that were already in the market place.

GRRR!
