safety car
"So that plays a big part, especially when a safety car comes and it's a driver change..."
A safety car is a car that comes onto the track to slow down the race when there's an accident or danger. It helps keep drivers safe and can change how teams plan their races.
A safety car is deployed in motorsport to neutralize the race when there is a hazard on the track, allowing drivers to slow down and maintain a safe distance. It can significantly impact race strategy, especially during driver changes.
driver change
"...especially when a safety car comes and it's a driver change..."
A driver change is when one race driver switches places with another during a race. It's important for keeping the team competitive and can be tricky to do quickly.
A driver change refers to the process of swapping one driver for another during a race, typically in endurance racing. This is a critical moment that can affect the team's overall performance and strategy.
tyres
"What about tyres this year? We did something different in recent years..."
Tyres are the rubber parts of a car that touch the road. They are important for how well a car can grip the road and perform during a race.
Tyres are crucial components of a vehicle that affect grip, handling, and overall performance. Different types of tyres are used depending on the racing conditions and strategies.
strategically
"...strategically what they'll do there?"
Strategically means planning how to do something in the best way possible. In racing, teams think ahead about when to change tyres or drivers to win.
In racing, strategy refers to the planning and decision-making processes that teams use to optimize performance during a race, including when to change tyres or make driver changes.
new tyre
"Yeah, so it is the first time we've been here on this new tyre..."
A new tyre is a type of tyre that has just been made or changed. It can help cars perform better in races, and teams want to know how it works.
A new tyre in racing refers to a recently developed or introduced tyre compound that may offer different performance characteristics compared to previous versions. Teams often test these to improve their competitive edge.
camber
"in terms of camber over the years and so on."
Camber is how the wheels are tilted when you look at them from the front. If they lean in or out, it can change how the car drives and how quickly the tires wear out.
Camber refers to the angle of the wheels in relation to the road surface. A positive camber means the top of the wheel is tilted outward, while a negative camber means it is tilted inward. Adjusting camber can affect a car's handling and tire wear.
aerodynamic force
"To get that, you need a lot of aerodynamic force, I suppose, so you have high wing settings, but that hurts you all the way down the bottom of the mountain."
Aerodynamic force is the push or pull from the air when a car is moving. It can help keep the car on the ground, but if there's too much, it can slow the car down.
Aerodynamic force is the pressure exerted by air as a vehicle moves through it. This force can create downforce, which helps keep the car stable at high speeds, especially in corners. However, too much downforce can increase drag, slowing the car down.
straight line speed
"So in terms of your car, you want to maximize your straight line speed, but you also want to provide the co-drivers, especially stability across the top."
Straight line speed is how fast a car can go when it's driving straight ahead. It's important for racing and depends on how powerful the car is and how heavy it is.
Straight line speed refers to how fast a car can go in a straight path without turning. It's an important performance metric for racing and can be influenced by factors like engine power, weight, and aerodynamics.
tyre delaminating
"I don't think we'll see the issues that we have in the past with tyres delaminating just because of the way this tyre compound is."
Tyre delaminating means the layers of the tire start to come apart, which can make the tire unsafe to drive on. It usually happens when tires get too hot or worn out.
Tyre delaminating occurs when the layers of a tire separate, which can lead to loss of traction and control. This is often caused by overheating or excessive wear.
tyre compound
"just because of the way this tyre compound is. So the teams may well push those cambers a bit further than they have in the past."
Tyre compound is the special mix of materials that make up a tire. It helps determine how well the tire grips the road and how long it lasts.
