The purpose of this vehicle is exactly as manifested on this site: tons of discussion and brand awareness. About top speed: rolling/ground resistance increases linearly with speed, but air resistance increases by the square of the increments. Simply put, it takes almost logarithmic increases in power output to achieve a higher top end, all else being equal. A teardrop shaped vehicle (the shape with the lowest drag) can reach relatively high speeds with modest power, but may take a while to reach that speed. Brute force accelerates the vehicle up to 8-9/10 or so of the eventual top speed quickly, but the last few MPH will depend heavily on drag and will accumulate slowly. Regarding this vehicle's top speed. The main issue is probably not what IT can do, but whether the rider can stay on it. A Popular Mechanics article on this vehicle quoted a motorbike expert who stated that at anything close to the purported top speed, the rider, whose arched back resembles a wing, will likely be ripped right off the bike. Of course, one can probably Kevlar-strap the rider on it and hope for the best.... |

"Ok, I'm not an expert, though I have studied cars since I was 12 and I am currently a student at the Herff College of Engineering as a Mechanical Engineering major. There is no ""plateu"", air resistance is just that: air RESISTANCE. Resistance is merely another force factored into the equation. The truck example is the most effective analogy. With enough energy exerted to move the vehicle in a forward direction, drag coefficients can become negligible. Another thing... Every time I look at this bike, the top speed goes up. The first time I looked, the top speed was just over 300mph. Now it is rumored to be 400+ !?! With this much power applied to such a lightweight vehicle, gearing is the single most important factor in determining top speed. Lastly, the comparison to a dragster should be thrown out completely. Dragsters are built to run on a 1/4 mile stretch and only on a 1/4 mile stretch. The top speed of a vehicle (i.e. the 300mph+ Tomahawk) is not calculated based on a 1/4 mile run. Dragster power delivery consists of a multi-puck clutch and a differential. Their final drive ratio is always the same. With a standard transmission with multiple gears on a longer stretch, a dragster WOULD do well over 400mph." |

ive i hav received alot of emails regarding my previous comments, about the aclaimed topspeed of the tomahawk, let me firstly jus say that i do NOT hate this car!!!i think its an amazing piece of machinery and i'm glad dodge had the balls to build something like this, but i do not believe its capable of doing 400mph+ , the acceration seems more believable but 400mph cmon!! not even dragsters manage that!!!(personally i think there must have been a typo im sure they meant 400km/h and not mph). Secondly aerodynamics ARE the single most important factor in gainin top end speed, its tru that power to weight ratios also play a huge part, but eventually u'll reach a plateau where u cant go any faster,despite addin more power topspeed will be the same cos u'll face more air resistance and more drag (an equlibrium if u will).Many people have written to me and seem to think power is all important to them i say learn from history! a good example is the MG EX 181, it achived a top speed of 254mph, with jus a 1.5 litre supercharged straight four engine, producing just 300bhp!! the reason it got such a high speed was because of its aerodynamic tear drop shape (if ya dont believe it check it out for ur self its on this website),to further prove a point,the AC cobra couldnt get a higher topspeed on the mulsane straight then its ferrari rival ,even though it had a better power to weight ratio, this was again due to aerodynamics. while its tru most peeps cant calculate drag coefficiants,(joiless stand and take a bow lol ),stating that brute power can over aerodynamics, by giving bullets as an example is ridiculess ,firstly bulletts unlike cars dont meet any rolling resistances,i.e they arnt in contact with the ground, and so dont have to worry about the drivin surfaces and terrain (if u've eva driven on mud,ice or any slippery surfaces u'd know wot im talkin about)but thats a whole differrent story,i do appologuise to the moderators if my comments sound like a naggin dicussion but cant be bothered to reply to every email i received, i hope this has cleared things up |

"I get sick of hearing about ""drag coefficents"" whenever something like this comes along. Check this out: most people don't have the math skills to calculate coefficents. I know I don't. But here's a secret: The fastest truck in the world is a snub-nosed semi propelled by three jet engines. It's about as aerodynamic as a cinder block. Why is it so fast? Simple: brute power. The Tomahawk can go fast because it's got enough engine for a pick up truck. Think of it like this: the .50 Action Express is a bigger round, but the .475 Casull is more powerful because it's a smaller bullet in a huge, overpacked shell. They took a monster engine and stuffed into a custom-built rocket because even aerodynamics can be overcome with enough gunpowder." |

When I first saw this bike I didn't really understand what I was looking at. I mean it all just didn't click in. Needless to say, I'm excited. Imagine! What's next? Since I was a young girl, kneehigh to a grasshopper, I've wanted bikes, lots of them, powerful and just plain cool. And though this isn't near my dream-bike, it's a step in the right direction. Kudos to it's creators, I await your next design. |
| where? |

Hoooooly crap! I need it! I want it! Where can I get one? Is Dodge going to start prodcuing this soon? I ride a Honda CBR 1100XX right now and I would trade it in a second for this beast of a machine! I think all I can say is WOohoO! I'm a fan of speed and this certainly does that. The only thing better than going fast is looking good while doing it and this certainly accomplishes that! If Dodge lets this roll out the door there is going to be a lot of people like me who are going to snag it up! Damn! I love it! |
| top speed & production |

"The guy said that there is a possibility for a limited production run. But nothings final yet. As to the gass stuff. I'm not so sure it would use all that much, think about it, how light is this thing? You could cruise up to 60-70mph, and bairly be hitting 2,000 rpm's or less (with proper gearing). But top speed, that's the real kicker, I know I said 400mph, other said 300+, but realistically, top speed is regulated by how well you can hold on. At that point I'm not sure it would make 300; but ya know what? I'd love to fing out." |

A wonderful display of expressionism and bored people playing with bigger toys than most of us. Thank God for madness, there is some originality in the big companies, let's hope it trickles down towards the rest. One minor point, I wish normal Dodge products had this build quality, there products always seem to have the tactile quality of the McDonalds bins . . . |
