When you like films, enjoy the story telling, good acting, pace and having a keen eye for the details, you will progress to enjoying films so bad they are unmissable. In the same vein, bad cars, by showing their flaws, make us understand the deeper complexity of crafting good ones. The 1989 Eurobrun F1 could be an example. Let us examine it. In part, the team were ex-Alfa Romeo Racing, and results in 1988 were reasonable. Eleventh in the Hungarian GP, on the grid several times. But when part of the team left in 1988 and the budget was cut, they were in trouble. Its best result during the 1989 season was not qualifying for the Brazilian Grand Prix. I say best as for the rest of the season the team did…

culture clash

Maybe I’m being too kind, but I think some of the criticism regarding the Baku F1 first practice farce, in particular Kimi Räikkönen’s pop at the FIA – ‘Formula 1 was made to look amateur’ – was a tad harsh, especially bearing in mind the recent sudden loss of the very capable Charlie Whiting, previously responsible for overseeing track safety. Anyway, it wasn’t only the FIA’s responsibility. The circuit organisation was at fault, as evidenced by its commitment to rightly compensate Williams for the serious damage to its FW42. Yes, it was a very embarrassing couple of gaffes, potentially very dangerous, and they should never have happened and must never be repeated. However, it does illustrate just how amazingly well organised and run grands prix are. Especially given the complexity of…

There are many who will look at the results of the FIA World Endurance Championship (WEC) this year, judge the performance of the Toyota hybrids far beyond that of the non-hybrid cars, and lay blame at the door of the Equivalence of Technology (EoT). This is the process in which technology is balanced according to the best in class, and was originally introduced with new hybrid rules in 2014. It was intended to allow petrol and diesel engines to compete, as well as the multiple amounts of energy storage each hybrid solution could carry. Once Audi’s diesel stopped racing at the end of 2016, and Porsche followed with its petrol-powered 919 in 2017, attention has turned towards the least considered group, that of the non-hybrids that was open to non-manufacturers…

‘This is going to be another difficult exercise’ The 2018 Le Mans 24 Hours saw a record low number of overtakes in two classes, GTE Pro and LMP2. The former saw just nine changes of lead at the start / finish line over the course of the 24 hours, while LMP2 was even worse – just three in the first 10 laps, and then nothing for the next 23 hours. Part of that was the balance of performance between the cars, part was the safety car procedure, and part was the pit stop regulations that limited strategic options. The FIA and ACO took a view on that and elected to introduce the Sentronics fuel flow meter into the GTE category for the first time to accurately gauge fuel consumption, eliminate the 14-lap…

There is a reason why the F1 pit lane is obsessed with tyres, and it’s because tyre management is the single biggest performance differentiator between all the teams across the grid. You can have all the horsepower and downforce in the world, but if you can’t transform that load into tyre grip, you will forever lose lap time. Teams use every trick in the book to not only try and bring the tyres up to their optimum working temperature, but to maintain that temperature throughout the race. The latter is particularly challenging because as the rubber wears away during longer stints, there is less tread to generate that internal heat, and tyre carcass temperatures decrease and drop out of the working window. When engineers say tyre management is a ‘black art’,…

formula 1 2021

In 2021, Formula 1 is controversially set to adopt single make brakes and wheels. As the sport seeks to create a radical new set of technical regulations, it has targeted a number of areas to introduce spec components to reduce costs, and the entire brake system and wheel rims are the latest parts of the car for which the FIA has issued an invitation to tender for a single design supply deal. When it was announced in 2018 that the wheel rims will increase in size from the current 13 inch to 18 inch – a direct result of the adoption of new, low-profile tyres – it had been expected that the present situation where teams work with outside companies to develop bespoke wheel centre designs would continue, but it now…
