RE: Cosworth's 1000hp 6.5-litre V12: PH Meets

What a weapon! Sounds incredible and I suspect even better once flying round a race track!

We want Can Am back, do we...?

Great vid, thanks for highlighting.

A modern car that is genuinely exciting to see come together, absolutely love this project and really has that element of "special" that IMO none of the other current crop of super/hypercars have captured.

Totally agreed - Bruce Wood is extremely candid about revealing some other details of the car as well when talking about the engine bay etc.

What a fantastic bit of kit.

A three cylinder engine putting out 250hp... I can think of a few things to do with that!

Who would have thought in this day and age that there's a manufacturer still willing to build a NA V12 engine instead of taking the comparatively easier route of just going with small capacity and FI.

Hats off to them, and Mazda, for sticking with HC.

This is the most exciting new supercar since the McLaren F1. Nothing else comes close.

[Limpet]

Sounds like a pre-turbo F1 car. Lovely.

One question - the article mentions that timing chains wouldn't cope with the 11,000 RPM limiter, but most bike engines use chains, and often rev to 15,000+ RPM. Is this really the reason chains weren't selected?

Narrow range of rotational speed on bike engines and usually far smaller capacity means less vibration/torque etc on the chain?

How can this be EU emission friendly - WOW!!!, can Cosworth now sort out Brexit too.....

[Skylab]

That is what they need in F1 . Wonderful well done Cosworth.

Can anyone put more meat on the bones of this statement?

"but that wasn't really the priority here, and if you want power rather than economy port injection is slightly better, and it also meant we didn't need a GPF."

I’d like to understand why. Why does port injection allow the GPF to go?

M U S I C !

That really is a perfect combination of epic engineering and a glorious sound.

this, this and this!

nothing else has made me so excited about a car I'll never be able to own

The chains on a bike aren't 1.5m long turning four camshafts that are each 75cm long and opening 6 valves

I can't imagine it'd be smooth enough to really use though.

Port Injection can reduce particulate emissions, probably enough to comply with current regs.

Direct injection allows lower CO2 but at the cost of higher particulates. Port injection gives lower particulates but at the cost of higher CO2...they don't care about CO2 for this car but there's legal requirements on particulates.

Well.....the more relevant statement would be the direct injection greatly increases particulate emissions in Gasoline engines as a leaner burn creates more during combustion. But yes...baiscally port injection reduces particulate emissions because it's not possible for the mixture to burn as lean as it would in a direct injection cylinder.
