Land Speed Record.

[Kerbolone]

HX engine on wheels, reached 4460m/s before it shattered (13.1 mach)

Had to rotate the engine so that the craft doesn't take off due to Kerbin's surface curve.

It did not break any records but I think Bill liked his SRB Ute

[1chrisA]

I just got up to 1,271 m/s on KSP 1.0

[Reily]

I had a weird glitch with this one plane i made and got it go go over 8000m/s

[Sharpy]

318m/s! :-D The way it works is: I blast down the runway, at the end I eject the cockpit section. I tried finding a straight and long patch of land but could not find anything better than the runway.

The land next to the runway.

Turn your vehicle 180 degrees in VAB. Drive up to the hills. Turn around. Blast off parallel to the runway.

For a slightly longer strip, go along the hills to the corner by the sea and turn around, to pass by the corner of R&D, diagonally through KSC grounds.

Want a really long strip of flat terrain? Go to Minmus. But you'll need extra engines vectoring downwards or you'll enter orbit while still on the ground.

The fastest I've ever gotten a wheeled vehicle is 1742m/s on the runway using about 300 Sepratrons and airplane wheels. And every once in a while, the driver managed to survive. But usually it would go cartwheeling about 1/2way down the runway and hit the SPH.

[GDJ]

110 m/s on a large rover, wheel driven.

Everything was going well, then I hit a bump or a ripple in the terrain, lost a wheel assembly, then the whole thing shattered.

1 Kerbal survived.

What are these "wheels" you speak of?

Here's the fastest land girder I've ever built. 628 m/s all on the runway with a complete stop and Jeb survived.

Edit: The F3 states maximum acceleration of only 1.8g. That can't be right. The run time was 5 seconds to 628 m/s, which breaks down to 125.6 m/s^2, or 12.8g! Since Jeb is accelerating butt first, he must have gotten some major red-out due to negative Gs.

How do you get past the transonic instability? I find that even with very wide wheelbases it gets really shaky and crashes around 320m/s.

[SpenSpaceCorp]

Using infinite fuel, around 1100-1200 m/s before the end of the runway. (I believe I also ignored max temperature lol)

I mean... couldn't you just turn this on it's side if infinite fuel is okay?

[Geschosskopf]

What are these "wheels" you speak of?l]

The "small gear bay" airiplane landing gear.

[richfiles]

My best survivable run is 458m/s which is over 1022mph. I have done 462 in the same car but didn't have Dxtory recording. Can anyone beat me without killing Jeb?

Jeb: "I can has speed naow?"

You: "Yes Jeb, you can has all the speed."

That you achieve this with not only a surviving pilot, but without vessel deconstruction... or even leaving the runway, is exquisitely amazing!

YOU, can has all the speed!

I managed 1250m/s.

Kerbal Reporter: "Can you describe the experience?"

Jeb: "WhahahahaaaaaaaaaAAAAAAAAAHHHHHHH!!!"

Fastest I ever did was Mach 1.4 at the North Pole, using FAR.

Heavy on mods, but very, very sexeh speed run!

Definitely win on style points! Bing-de-do-de-do... What was that alarm sound? Breaking Mach or something? That part of RPM?

[matissVEVO]

~360 m/s

[PCanas]

962m/s

I think the only mod that would change something is FAR. No cheats.

[Gaarst]

562 m/s (Mach 1.65 asl) with Jeb on board, surviving and stopping before the end of the Runway !

Though I used SpaceY and Real Fuels...

Don't believe KSP on the G-force, it actually went up to 29.5 G according to KER

[Skalou]

The fastest snail in the world!

880m/s!

cooked perfectly, time to lunch!

[xebx]

717 m/s at end of runway (mach 2.04), Kerbal survived and is happy

Stock and KER+KJR

[Blazing Sun]

Well, it's no 4460 m/s, but I got 964 m/s using stock parts and no cheats.

[RA3236]

Almost a kms on the runway: strapping ten BACC SRBs to wheels. Also with rockets to keep it on the ground. To bad it exploded due to reentry heating.

im kidding, more like 500.

[Slipknot7246170]

I can get to 285 but then it flips and explodes

[Stickysheep]

hello I got 738 look at my vid on youtube name stickysheep I did this on a run way that's the challenge to do it on earth on the runway

[Chocolat Oreos]

The mod i used for the main SRB: procedural parts

The mod that shows the damage: Kerbal Crash System

it does survive

But that doesn't survive D: poor kerbal

[THE NARWHAL]

Oh boy, this looks fun. I'm working on a craft now, let's do this.
