Name a modern sports car (i.e released in the last decade) that uses an I6? The BMW Z range...hardly the best are they?

Got any more made up facts for us to laugh at?

How about sports truck?

Tell me how any of it (talk of Ferrari V12's) relates specifically to an I6 NA configuration at a price point suitable for TVR as a startup?

This is the crux of the discussion that I've yet to see a sensible answer to.

RoverP6B, to keep the thread on track are you going to offer your thoughts on this question?

I'm trying to work out what the point of debating straight 6s is anyway. There are good and bad straight 6s. There are good and bad V8s.

That's all irrelevant because the engine in question WILL BE a V8 according to the best sources we have for it.

There is only one person hell bent on it, and he keeps loudly making his fantastical points and derailing the discussion on all threads concerning the new TVR. He's either a damn good troll, or a nut job.

I stand corrected as to the purpose of the Speed Six racers, but at least it confirms the Speed Six did go racing.

Z4 isn't fabulous, but then nothing is now. New straight sixes on their way from Jaguar and Mercedes-Benz though...

The point being that a naturally-aspirated inline six engine (or a pair thereof with a common crank) can produce competitive power, meet emissions and still have headroom in terms of piston speeds.

Without wishing to go too far off topic, they're pretty good aren't they? Have only heard criticisms of ride (runflats) and slightly dead steering on the non-M versions. Z4M is well thought of isn't it?

..

And the cars with their bonded CF run around the tubular cage was one of the best in it's class as were some of the drivers, yet you'll never guess the types of engines that consistently out performed and out lasted the S6 in almost every race?

I know that all too well.

Can we have a separate thread to discuss the merits of straight 6 engines?

[HarryW]

Seriously guys can we just ignore the nut job....

There were clearly issues with the build quality of the Speed Six engine, but it's a fine design which others (e.g. TVR Power) have comprehensively sorted into one of the best engines around. In a racing application, the primary and secondary order balance of the I6 is crucial. V8s, one way or another, will have a tendency to vibrate significantly, and the only ways of damping this out involve robbing throttle response.

It clearly fking isn't, because the majority of racing engines appear to be V8s and inline 4s!

tvr will build one speed six just for you....do you want to buy it ?

You've never owned a TVR or spent any real time with a TVR, you know almost nothing of the business or its history and yet you repeatedly keep trying to pass off your 'knowledge' as facts to people who have owned numerous TVRs over decades, been involved in the racing, involved in the S6 rebuilds and redesigns, knew PW personally and know LNT and generally have huge experience of the brand first hand.

The S6 had design issues. So let's correct that statement of 'fact'.

And the S6 isn't one of the best engines around.

It's a great engine with good character and if you throw many thousands at it you can get one that will last reasonably well.

That doesn't answer the question. Again the question is; how do you propose a competitive and compliant I6 NA engine be delivered at a price point workable for TVR as a startup aiming to release a sub 75 grand car?

And as a reminder, the following is a quote from LE in a Top Gear interview:
"We knew if we revived the Speed Six - and we looked at doing so - it wouldn’t last long in terms of emissions demands. So we had to base our engine on a block that would be ultra reliable,"

Please elaborate what you know about the Speed Six, and existing NA I6's in general that LE and his team, inclusive of Cosworth, don't?

Here's one with a supercharger

600hp+. For a while.

[m3jappa]

So will the new engines be the ls3 crate engines, breathed on by cosworth?

If so great news IMO. And that comes from someone who owns a tvr power rebuilt Tuscan with what seems to be an incredibly strong engine and someone who has used a ls3 in a corvette which I actually loved, lots of torque, revvy and just solid.

Fantastic, why couldn't they get it to work?

Not for me, anything LS just says kit car.

But if I'm honest my next car will be Italian anyway.

[m3jappa]

Have you used one though? They really are good engines, and when was corvette a kit car?

Another plus is it won't be hard to make the new car into a 600+bhp monster should you desire.
