What is the rake of a car?

What is the rake of a car?

Rake refers to the car altitude created by raising rear ride height in relation to front ride height, effectively setting the car up with an upward slope front-to-rear.

What does low-rake car mean?

A low-rake car has a much reduced angle, and so the incline of the diffuser means it’s much closer to the ground. Rake is one of the key parts of the aerodynamic setup of a car, and is one of the aspects that defines a concept of a car – where everything else must be built around it.

Is Ferrari a high rake car?

In terms of aerodynamics, the Mercedes is a low-rake car, the Ferrari an increasingly high-rake one (following the example set by Red Bull). Generally, the closer to the ground the leading edge of the floor runs, the more downforce is produced thanks to the principle of ground effect.

How does car rake affect handling?

It is the distance between the bottom of the car and the ground, measured at the front and rear. Higher positive rake increases the downforce of the car (up to a point), which gives more grip in corners but also more drag resistance (resulting in lower speeds) on the straights.

How does rake affect speed?

In conclusion, a propeller with high rake preserves more water and directs it to the propeller’s hub, allowing us consequently to mount our engine higher or trim up it more, achieving higher final speed.

What does rake mean in Old English?

In a historical context, a rake (short for rakehell, analogous to “hellraiser”) was a man who was habituated to immoral conduct, particularly womanising. Often, a rake was also prodigal, wasting his (usually inherited) fortune on gambling, wine, women and song, and incurring lavish debts in the process.

Is McLaren a high rake car?

We’ve kind of been a high rake car but on the medium to lower end of that, certainly not extreme. “Whether that’s had a larger impact on cars with a slightly lower ride height is difficult to tell, it depends where you’re coming from.

Is McLaren low rake or high rake?

McLaren is continuing with a “medium-to-lower-end” version of the high-rake design on its 2021 challenger but Key has predicted that both philosophies will merge as the season goes on. “It is a little bit early to say,” Key replied when asked which concept he believes to be the best.

Which F1 cars have high rake?

A high-rake F1 car has a higher ride height, with the car’s nose pointing down more aggressively. Pioneering the concept in F1, Red Bull’s high rake and shorter wheelbase concept increases the volume of air that goes through the diffuser, due to increased ground clearance. Red Bull’s high-rake car.

Why do SUVS have rake?

To start with, rake is the car altitude created as a result of the relation between rear ride height and front ride height, giving the car a front-to-rear upward slope. Changing the rake, also known as the ride height, means the roll center will be moved and grip on that end of the vehicle is reduced.

What is the difference between rake and trail?

Rake (also called caster) is the angle of a motorcycle’s steering head of the frame (A). Trail (B) is measured in distance (inches or millimeters) between the point of the front wheel’s contact with the ground and a line drawn through the axis of the steering head.
