This will be a general purpose thread for F1 news and pings that really don't require a thread of their own.
I’ve NEVER been a fan of LV...and I’ve been there 150 times (mostly for work).
U so funny!
U make grate jokie!
From some of the Foo Foo outfits Hamilton wears, it looks like he’s starting a new sex.
twice, and i wasn’t impressed...
I’ve had more fun at AC (good ol’days), Mohegan Sun and Foxwoods.
LV is a bore and the county was named after William Clarke who built the town as an overnight stop for his railroad fro SLC to LV.
Clarke bribed his way to become a senator in Montana in 1890 and the opposition party objected because he exceeded the $2,000 campaign limit (his bribes were all $5,000 each).
His chief rival — Dailey, Aldo a Copper King — died and Clarke ran unopposed and served in the US Senate for 1 term.
LV exists due to a Montana Senator...
Aldo = also
Sheeshe!
and it’s hot...

Dealing with porpoising has been a challenge for several Formula 1 teams in the new ground-effect era. As a result, the engineering company ENGYS decided to explore the problem and developed useful techniques to simulate and visualize the phenomenon.
The problem was at its worst in 2022, with multiple drivers complaining about the issue before FIA rule changes largely eliminated the problem for 2023. Notably, many teams failed to foresee the extent of the issue before on-track testing, having not picked up the gravity of the problem in design simulations or wind tunnel testing. As highlighted by ENGYS in a blog post, that's not a huge surprise, given the difficulty of simulating the phenomenon using Computational Fluid Dynamics (CFD) software.
Porpoising involves severe vertical oscillations as an F1 car's underbody gets too close to the ground. When this happens, the underfloor aerodynamics can stall, leading to a sudden reduction of downforce. This leads to the car rising in height, at least until the aero kicks back in and pulls it down again. When this happens rapidly, it leads to the uncomfortable porpoising phenomenon.
Porpoising is difficult to simulate due to a variety of factors. One is that typically, CFD simulations and wind tunnel work both fail to accurately simulate the action of the car as a whole system, including the actions of the car's tires and suspension. As explained by McLaren's James Key last year, the porpoising phenomenon is not solely down to aerodynamic action, but by the interaction of the forces with the vehicle's suspension, too. If that isn't accounted for, the problem won't reveal itself.
As for CFD simulations, they face a greater problem. They simulate flow by creating a "mesh" of distinct volumes around the car. The flow parameters are calculated for each mesh cell, and the aerodynamic behavior can thus be simulated.
The problem with doing this for porpoising is that it involves the car's underbody becoming ever closer to the track surface. This creates difficulties as the CFD simulation mesh must become ever denser and smaller to predict the flow in this vanishingly small space. As the mesh becomes finer and finer, it becomes more expensive to simulate, computationally speaking, particularly regarding F1's restrictions on simulation time.
ENGYS developed a technique to get around this problem. If you're not an expert in CFD, it won't make a lot of sense, but it involves simulating the situation as if the ground is moving relative to the car. The CFD software then snaps a mesh to the track surface underneath the car, which changes as the car's ride height changes.
Even with these optimizations, and only simulating half a car, the simulation still took 7.5 hours to model 0.5 seconds of porpoising behavior on a 128-core computer. F1 places significant restrictions on the amount of CFD simulation that teams are allowed to use, so any efficiency gains in this area are highly useful.
If you're studying at university and want to get into motorsport, diving into this area could serve you very well. Understanding how simulations can best be made to represent the real world is key to success, and it has fast become one of the biggest parts of top-tier motorsport.
Childress receives annual Argetsinger Award
NASCAR race car driver and team owner Richard Childress was honored Friday night at a dinner at the Watkins Glen Harbor Hotel with the annual Cameron R. Argetsinger Award for Outstanding Contributions to Motorsports presented by the International Motor Racing Research Center. Childress, who drove in 285 races in NASCAR’s premier series before turning to team ownership, recorded several season championships with Dale Earnhardt driving his #3 car. The late Cameron Argetsinger conceived of and organized the first road racing in Watkins Glen — in what would become the Watkins Glen Grand Prix. Previous winners of the award have included Chip Ganassi, Richard Petty, Roger Penske, Mario Andretti, The France Family, Bobby Rahal, Lyn St. James and Mike Helton. The emcee for Friday night’s event, as in past years, was Dr. Jerry Punch, who concluded the ceremony by interviewing Childress on stage about the latter’s storied career.
he was in the flow of traffic, nothing more... leave it to the frogs
F1 world champion Max Verstappen ‘could be prosecuted in France’ over a video of him driving 20mph over the speed limit in Aston Martin’s new £3m hyper car in a tunnel near Monaco
Hilarious!
Cut a Check Max,
Fart in Their general direction!
He was probably going the same pace as the traffic flow. They are treating him like Donald Trump.
Now the question that begs for an answer is...
What is the FIA going to do to Max over this ?
Gosh! 14 whole mph over the speed limit? Here in America- traffic goes about 20 at least! some dolt said he was ‘endangering other people’s lives’ yet i bet all traffic was going near that speed- and max is one of the best drivers in the world at speed-
The ‘Outrage Machine” is working overtime in france apparently-
he was... the video shows it
yeah, that and a lil Max Derangement Syndrome...
14 over???
We should have let the Germans have France.
