Oh Jesus not this again - we get it every year.

A car would be faster, based on the simple fact that the side-cars are more car than bike, getting on for two and half times the weight of a superbike, yet have the same engine and still post a lap time only 15mph down. Add an extra wheel, remove the passenger and increase the BHP and you'd smash the lap time.

As someone said, much of the TT is flat out - which would inherently favour a bike... a 200mph car with sufficient downforce would require a lot of power - at the expense of agility and slow corner traction.

A lot of the TT course is very narrow, which again favours bikes - some of the stuff that the bikes straight line would represent significant corners to a car.

I'd still put money on the bike.
But, are the narrow sections including change of directions?

The Autocar Cadwell park video, Bike vs GTR say that the two areas where the car had an advantage are chicanes (+ alpine loop) and braking.

So my logic is that straight, or single direction narrow bits will favour the bike, a narrow section with a few changes in it may favour the car.

My moneys on the car. But, are we making a fair comparison? Are the IOM TT bikes not race bikes? What about road vs road?
I mean the very fast sections which include corners which to a bike is nothing more than a slight tilt as the bike can straight line - if you watch this again

From 1.50 onwards there's a long section where the bike is between 130 and 170mph, a lot of it is a just a simple lift and flick on a bike. Whereas a car with sufficient downforce and suspension to corner/stable at 170mph like the bike would be all over the place on those roads.

A road going bike is far closer to it's IOM race variant than most road cars are to their racing versions (Grp N excluded), so it's a moot point.

but what length of road do you need to get a loony lotus to 170? A lot more than to get a bike there.

Exiting a corner at 80, the bikes are up to 150 just a few hundred yards later. And i think that is where they have cars pegged. Their mid- to high-speed acceleration is simply devastating.
not as long as you think, yes, probably not as fast as a bike, but far from slow.

for example:

less than ideal conditions, doing 0-140 in ~12 sec's

they are warmed up, but basically pretty similar to stock bikes you or i can buy. Comparing them to a single-purpose single-seater open-wheeled racing cars wouldn't be fair.
But to be fair, modern road bikes are made with the purpose of superbike racing in mind and with data from previous racing. It's not like say 15 years ago where they made the best road bike possible, and then turned it into the best race bike possible.

granted, but sportscars are developed along similar principles. Perhaps not to the same extent, but similar. And they aren't racing on tracks, they're racing on the same roads that the stock bikes are developed for. That is significant - there are usable, practical machines, not specialised one-trick ponies.

quick, granted, but that is only as quick as the original fireblade, 125bhp and now 18 years old.

Todays senior-class bikes are closing-in on double the power, much better brakes and suspension, and a lot less weight. I think the elise would get murdered in anything less than a proper downpour.

what you are describing is akin to an F1 car. Not really relevant to this road-based, production-based, cars vs bikes debate.

compare the average price of a bike to the price of the bikes that compete in the TT. From the average price of a car, calculate what you're allowed to spend on the car.

a car will murder a bike round a track, way more grip and much much better braking.

like I said, less than ideal, that car was fuels for a 1+ hours racing.

Steve Gugliemi's Time attack car has double the power of the one in that video.

The term "production car" is vague though, and open to interpretation. Afterall, you can buy a radical with a number plate, which is akin to what I'm describing.

not sure that is fair, but lets say that formula gives you 1m to spend on a car.

A Great start, but if that is the game then you will also have to start with a best-selling sportscar (say a 911) and be restricted to using its standard chassis/body and engine block.

Not so easy now...

fair enough, lets take the radical. Designed without compromise and a fabulous piece of kit. Just like the bikes.

Granted, it's faster than the bikes on some tracks. But this isn't some tracks, it's some bumpy a- and b-roads.

Would it be faster than production class iom bikes round the iom. I guess no, you guess yes.

Can anyone find anything to prove or indicate either way?

I dunno, a 911 GT2 RS with the remainder of the 800k thrown at should be insanely fast and capable. In standard road trim its ability to go 100-200 mph is enough to scare quite a few fast bikes. A decent suspension set up, sticky tyres and a little more down force, would undoubtedly yield interesting results.

Original question. No.

Can a car lap quicker than a bike at any track? No.

I can't believe that people are so attached to their tin boxes that they actually believe a car can be quicker than a bike. rolleyes

What about a 1000bhp Nissan Skyline, Bugatti Veyron or a F1 car? F1 isn't a car it's a gokart and would fall apart, the Veyron would run out of Petrol half way and the Skyline may be good for quarter mile runs or like driftin' in-it but would not be able to cope with the surface of the TT circuit. Skyline vs Wall would have a similar result to biker vs wall so go for it. WRC car would be close and fun to watch. Oh hang on they already do a Manx Rally and they're a lot slower. So much so that a twenty five year old E30 M3 made the WRC boys look stupid a few years ago.

Can a car beat a bike round the TT? No.


You can close the thread now.

Oh raw nerve touched there me thinks!

Bikes can be quick and are definitely more challenging, rewarding, exciting etc but cars are generally faster when things turn bendy and nadgery.

what?

a car has much bigger contact patches than any bike and this is what determines cornering speed and braking ability. This is the major factor in making a good laptime.

This F1 car didn't fall apart:

The "WRC boys" don't do the Manx rally confused

Everything else you wrote is utter nonsense.

This is a sweeping generalisation but I'd say road car vs road bike the bike would win it but race car vs race bike the car would take it round your average race track because of the extra grip you'd get from aero packages and slick tyres.

The TT course is a very different animal though, there are lots of sections involving left-right-left-right kinks in the road that the bike can straight line whereas a car would need to back off to take them.

Every TT, every time some kit car that'd be about as much use on the road as a horse on stilts sets a lap record at the ring, every time some WRX driver gets humilliated on a "B" road by a 125 rider with "L" plates, every Summer on any road.

Can a car be quicker than a bike round....blah.....blah.....blah?

Of course bikers are braver than car drivers. We don't have crumple zones, seat belts, air bags and a big metal cage to protect us. Bikes are more rewarding than cars because no matter how fast or what car I drive I feel like a passenger compared to being sat on a bike. No matter how powerfull and well set up a car can be for the track you'll come unstuck at the speed ramps as you exit the circuit. My GSXR is as fast as anything I have ever driven but I can get on turn the key and go anywhere. From the Nurburgring to the local news agents.

I hadn't noticed that line, that is funny! The Manx Rally uses different roads and besides due to FIA regs rally stages are not allowed to exceed a specific average MPH (which is set pretty low, think its about 120kph). So they couldn't use much of the TT course at all, even if they wanted to sadly.
