Given the shattering performance of the Mclaren P1 being equal to the fastest racing bikes up to 124mph but from there on destroys them and likewise destroys them in braking and cornering etc.

Do we think that the P1 laFerrari 918 or even a vastly cheaper Atom V8 would be able to beat the time given that a Suburu managed 118mph for the first half of the track but burnt its brakes so it slowed to c115mph overall average? That being a 340bhp car which in its own right is quick but its relative these hyper cars get to 200mph in so little time from standing start it must be a real possibility that these can go out there and utterly destroy the bike time.



Heck we may see these hyper cars getting close to the The Rings all time qualifying lap record yet being road cars and road usability.

With these cars I doubt we will ever see them try to beat the time but I think these answer all the challenges bikers have raised previously.

What's the PH opinion?

This could be a long thread.

I reckon an Atom V8 might have a shot, I can't see any of the hypercar manufacturers having a pop, too much chance of a high profile off at the IOM. The Impreza lap was very impressive, as far I recall, it was a road car upgraded for the task, not a stripped out shell rally special.

I'm sure the new hypercars, P1 especially could do it, but I don't think we'll see it. We're probably at a point now where there are a few road cars that could do well at the IOMTT, but I'm sure most of us can agree the trusty Peugeot 106 won't be troubling the lap time board soon.

Isn't the basic picture that at feasible speeds,
  • Bikes accelerate much faster than cars
  • Cars brake and corner much better than bikes.
So the answer is always a simple analysis of the ratio of straights to corners on a particular circuit. 37 mile IoM circuit has a lot of straights.

True but in this instance the car matches the acceleration of the fastest bike and above 124mph pulls hard away from them surely that's game set and match?

I personally think the ring should be scrapped and the new benchmark should be the IOM wink

In all seriousness though I think a P1 would probably do it, the weak point is the squishy bit behind the wheel. The faster the car the more margin there is for error on dangerous roads.

I've never actually attended the TT so haven't seen the roads in person. However, seen on TV some of the circuit looks very narrow which may in itself restrict the ability of a car to corner at speed. In other words, bends and curves may effectively be tighter radius for the car than they are for the bike.

By the way, I had the good fortune to be driven round Thruxton in the same Rover Vitesse which was used by Tony Pond for his record-breaking lap of IoM. Quite extraordinary.

I don't ride but I'm told that cars are better than bikes in tight turns. The bike needs time and space to lean side to side, the car can change direction instantly.

I remember (though it was a fair while back) because I watched some footage from FOS one time when Foggarty(?) took his bike up the hill. I was expecting him to destroy all others but he was actually quite slow. His race-rider excuse was that the track was too narrow so the cars had a huge advantage.

Yes, I remember it well. The new hypercars have set a bit of a new benchmark though. Like I say, we'll probably never see it, so it will remain unanswered.

Less, you mean?

The difference is that bikes are much narrower than what are relatively narrow roads so could probably take a much straigther line through the bends whereas a much relatively wider hyper car would probably run out of room each side when trying to take the same lines.

If we're on about any car having the best chance of cracking the IOM record, I vote for this (as I did in a similar thread):

Nope, top speed is far, far too slow. It's geared for about 120mph, and maximum traction out of tight hairpins. You need to be getting well over 180 to be in with a shout of beating IoM records.

Just a pumped up 106 then!

I don't have the knowledge to back it up, but I believe the cars have got to be fairly close. Equivalent (or greater) top speeds, 4WD (in the 918) and running on slicks I'd imagine they'd be within spitting distance.

I'd love to see an attempt in any case.

Why isn't that just a matter of gearing? Seriously... or have I missed the point?

I'm sure they could adjust the gearing.

And reduce the aero.
