It's a good job we don't have those cars from 81-82 with no suspension movement, those things were lethal. That is one thing F1 has definitely learnt from

Few posts missing the point of my comment in comment #2197 about the cars being less darty and more clumsy than previous F1 generations.
Absolutely not JUST about the weight, nor JUST about the wheelbase, nor JUST about the aero but rather a combination of all those things. In medium-fast corners, where the aero is doing its thing best, the current cars are pretty impressive but in lower speed corners, on bumpier street circuits as a couple of examples, the current cars are clumsy in comparison to previous iterations, less darty, more cumbersome. That was the point I was making - to me it's a great shame that F1 has lost that "edge" the cars always had in those situations and it would be great to see it back but alas I think it's unlikely. |

The irony is, that it’s the slower corners where the fans usually get to see the cars close up because the faster corners either have limited viewing or no viewing for safety reasons.
Heavier cars + longer wheelbase + higher COG is why the cars look less darty and nimble than the older generation. Also the teams moan about bodywork changes causing them “problems” is only a problem because they have basically shrunk the rear of the car down so much it’s like they are wearing a corset. There is ACRES of packaging room above the floor plan, it’s just the aerodynamics guys don’t want it used for that purpose as it would upset the airflow at the rear. |

though undecided if i like or dislike whether or not these current F1 cars can attack theae complexes at full throttle or not. To see how agile these cars are at speed is quite something. That they are on rails makea it more impressive. |

That's what I thought, it's a combination of all those things which is why I asked, wouldn't the long wheelbase also be a factor, as well as the weight? |

How to fix F1 - give us tyres that mean some will try and go a full race on one set.

The term weight is being used here instead of mass. Downforce is a force not a unit of weight The static weight becomes dynamic (or Kinetic force) when the car is in motion and is tending to keep pushing the car in an existing direction. Downforce provides extra traction to allow other forces to be used to overcome that Kinetic force. Ipso facto Aero generated downforce actually is the reason that F1 cars have the ability to translate motive power into acceleration, braking into deceleration or steering forces into cornering performance at high g levels. But then it,s just about eighty years since I did high school physics |

It's a tricky subject. Personally I don't think weight and mass is too much of a factor on the racing as the downforce. But this has been an interesting subject nonetheless. Learn something new all the time.

Weight, or more accurately mass, affects the movement of the car on all axes: vertical, longitudinal and lateral. Downforce/lift, is a downwards force which is produced by aero and allows the car to travel faster by increasing the vertical force on the tires, thus creating more grip. The mass is a factor because increasing the mass gives you extra "push" on the tires, but it also creates slower acceleration, longer braking distances and slower cornering. |

Yes, it is the mass that you have to accelerate (faster, braking, or change of direction).

80 year old physics classes aside the term "weight" is the simplist term to describe the effect of the load that is added to the tyre contact patch which in turn takes away the desired spectacle from the spectator POV for a lot of us. Engineering in F1 has actively sought to prevent the car moving about as in times past and it ain't going to come back if engineers can prevent it.

The mass is what you have to move around. The greater the mass the more effort it is to make it accelerate (in any direction). (All as you know ) |

The centripetal force of the tyres increases with weight. In a simple model this force is linear to the weight through the friction of the tyres. The force required to accelerate the car round the corner is also linear to mass. So, the mass is irrelevant. This is the case for a vehicle without downforce.
In a similar way the mass of a body does not effect how quickly it orbits around the sun. A pea or the Earth orbit’s the sun in one year if both 1 Astronomical Unit from the Sun. If you throw in downforce then the perfect balance between the in the physics which means mass is irrelevant doesn’t hold. A car with downforce does have a dependency with mass. I find this dynamic quite interesting. Also tyres friction coefficient isn’t necessarily linear to mass. I’ve taken Stephen Hawkins’ advice and tried to wire without using an equation! |

It’s just Vettel’s views that’s all. Not sure how accurate he is, but it shows once again how big a heart the guy has. But nothing really more than that
