#6 Inboard brake discs

.........(the only potential complication is that disc brakes near the diff are somehwat vulnerable to oil leaks)......

Exaserbated Made worse by the heat of the discs cooking the dif seals.

#7 Alloy engine block

Before you say that there are many cars that do have it....

Many automotive innovation were very quickly adopted across the industry: overhead valves (OHV), then overhead cam (OHC), then dual overhead cam (DOHC), and then alloy engine heads.... these features are now all commonplace.

But not so with alloy engine blocks... yes it is more expensive, but surely this will be offset by a massive weight reduction, which should aid both fuel economy and handling?

Yes still many new cars have good old iron blocks....

If my memories correct, Rover used this idea for V8 that they bought from Detroit.
Correct me if i'm wrong  

Yep, from Buick, to be precise... hence the B designation in Rover P2B.

Tri-rotor Wankel.  

I wouldn't rate this the same as the others... Wankel failed not because it did not pick up in the market, but because the engines were very short-lived with typical life span of 20-30k miles before major overhaul.

The thing bankrupted NSU in the seventies (they bet heavily on their Ro-80 exec saloon) and were then taken over by Audi.

So even though it was adopted by Mazda for the RX7/8, I would say it was a technological flop at the time rather then just a good/reasonable feature that the market did not warm up to.

I wasn't talking about regular dual-rotor Wankels. Those are/were in the RX2/3/4/7/8 and a few other models over a span of decades. The latest version is a good if thirsty engine.

There was a Corvette concept car in the 70's with a 3 or 4-rotor Wankel. If you want a lot of power in a small package maybe a 3 or 4 rotor Wankel with turbos . . .  

Interesting... I did not know that. Thanks...

Trouble is thta to make a block as strong as the cast iron equivalent, you need almost the same weight of alloy......or tolerate a weaker block or much more expensive precision casting setup.

They are more common place now though.........so its even more important to get the anti freeze mix right!

The Buick 215 engine........interestingly, Buick made more engines during the 2 years of production in the states than Rover did in the following 40 ish years of V8 production.

Whats worse is that they fettled the design and buggered the flow of the heads up (215 heads are highly sought after), the head mountings (they added an extra row of bolts which buggers the head gaskets on pre 95 engines) and quite simply worsened the original design.

Wasn't the P5b the Coupe & the P5 a normal Saloon :question

No. There was a coupe & saloon in both straight 6 & V8 ie B for Buick form http://www.roverp5club.org.uk/
They would be towards the top of my lottery winning wish list.

Ahaa. You learn sumat new every day

It was cos the P5 was such a big heavy car that the original straight 6 was a bit under powered for it, hence the need for something with a little more poke.
Had been trialed as a marine engine before Buick abandoned it.
Head of Rover wouldn't let them put it in the car but the engineers did anyway.
Took MD along motorway at speeds that would now be illegal.
MD impressed when he learned.

Rest is history .... blah blah

Indeed... one of the best looking cars ever... which was also the basis of the recent Chrysler 300C.

Incidentally... does anyone remember the opening scene in Wim Winder's 1991 movie 'Until the End of the World'? The one with the Rover and the 'kisses sweeter than wine' soundtrack? A classic....

I always liked the look of the P5, especially the Coupe, but they where always too expensive for me at the time, so i had a P6 instead (well 3 actually) There was a black P5 that was local & it was a beaut.
It was driven by a young lad, only a bit younger than me & i always wondered how he afforded it

Odd choice for a pimp car though
