We Never Change, Do We?

It’s a rollercoaster ride for Formula 1 drivers at the moment, especially for those who are teetering on the brink of expulsion from their teams. We already know Heidfeld is being observed closely, and with the Alonso-to-BMW rumours getting stronger, he’s probably quite worried right now. Bourdais is also under scrutiny, having been told to shine just that little bit more.

Le Seb has hit back, though, and said to his team that there’s no point keeping him if they think he’s going to adapt to a car that he doesn’t like and isn’t working.

F1 Digest - Hungary Free Practice

We knew it was going to be a slow start to proceedings, but thankfully things livened up for the Free Practice sessions in Hungary. Listen to F1 Digest for a completely rundown of the action.

Free Practice 1

No action for 30 minutes, but once it got started there were some interesting things to note. Ferrari seemed to have the edge on McLaren, but how much of that was true pace and how much setup? Also, Vettel broke down.

Free Practice 2

This time round it was McLaren working their magic to take the lead, with Piquet in a ridiculous second. Plenty of tyre work, and also, Vettel broke down.

F1 People - Colin Chapman

Sidepodcast mini-series logo

Welcome to the second series of F1 People, seven short shows brought to you by Sidepodcast, chronicling the lives of important people in the world of F1. Last time round we looked at Michael Schumacher, Enzo Ferrari, Frank Williams and others. Obviously there are more than seven VIPs in F1, and we had several comments last time round suggesting people we may have missed. Thus, F1 People, series 2, is here to expand on our list, starting with Colin Chapman.

Anthony Colin Bruce Chapman was born on the 19th May 1928, in London, where he grew up and went to University to study mechanical engineering. While he was a student, he learnt to fly and joined the Royal Air Force when he was 20. He wasn’t there for long, although the experience gave him a taste for aeronautical engineering that transferred to his love of cars. After leaving the RAF, Chapman became a member of the 750 Motor Club, a UK based racing club that specialises in Austin’s.

The first car that Chapman built was based around a 1930 Austin Seven and he named it Lotus. The car was entered into some minor races and was so successful that more versions were built. At this point, Chapman was working at the British Aluminium Company, but his girlfriend lent him the money to start up the Lotus Engineering Company. He partnered with Michael Allen and in 1953, Frank Costin joined the company to help create the Lotus Mk 8. The success of this car allowed Chapman to leave his job and work for Lotus full time. Whilst building and producing road and race cars, Chapman’s expertise was sought by Vanwall and BRM who both used him as a consultant to their racing teams.

Nuances of Downforce

Honda Racing

I’ve just been dipping into the latest issue of F1 Racing, the one with Lewis Hamilton looking mean and moody on the front cover. I started from the back, as I always do, consuming Nick Heidfeld’s recollections of meeting Shaquille O’Neal, the anatomy of a pit stop, and Ross Brawn’s to do list.

Tucked away in that last article are two sentences that are both incredibly enlightening, and at the same time, comedy gold.

“The former senior technical director, Shuhei Nakamoto (now deputy MD technical reporting to Ross Brawn)… had no prior F1 experience.”

“Nakamoto admits he didn’t grasp the nuances of downforce…”

Hang on a second, the technical director didn’t understand downforce? Doesn’t this seem slightly odd and/or scary?

I don’t know the interview technique for positions of this level, perhaps they don’t ask about your aerodynamic knowledge, assuming that if you’re applying for the job, you might have a clue what was going on. I’m wondering what my chances are of blagging my way in to a top level job.

It’s no wonder Honda struggled so badly last year, isn’t it?

History of F1 - 1970s

Sidepodcast mini-series logo

Welcome to Sidepodcast’s History of F1. So far we’ve travelled from the 1900s through to the end of the 1960s, and seen the Formula 1 World Championship begin to take shape, and some of the legendary drivers stamp their mark on it. Now we take a look at the 70s where safety concerns and car development were top of everyone’s priority list.

In 1970, the revolution of aerodynamic engineering began to take place. It started with the creation of wings, which meant more downforce for the cars. Essentially this meant they had more grip and could coast round corners much faster than previously. In the early days, the wings were not fastened particularly securely, and it wasn’t unheard of for them to fall off at unexpected moments. After a few too many accidents, wings were banned for a short time.

The early 70s saw the rise of a new star for Lotus, Emerson Fittipaldi, a young man from Brazil who won his first race in 1972. The rivalry between he and Jackie Stewart meant that the next four championships were alternated between the two of them, until Stewart retired in 1973. Stewart almost made it to the 100 Grand Prix mark, but gave up one short of the feat. Why would you do that?

In 1975, Ferrari began to make their comeback – despite the fact that the season was littered with protests about driver safety. In the Spanish race, a car came off the track and actually hit the crowd, killing four people, and causing some drivers to refuse to continue to participate.

Ferrari driver Niki Lauda won five races and had nine pole starts to take his first championship. He went on to win two more. The next year, 1976, Lauda was involved in a horrific accident at the Nurburgring, which saw his car burst into flames. Lauda suffered facial burns and inhaled toxic gases, so much that he was not expected to survive. However, Lauda did manage to pull through and was miraculously driving again only six weeks later. The Nurburgring track was taken off the calendar, but returned in a dramatically altered and much shorter state.

Niki Lauda’s main competition came in the form of James Hunt, a British driver for McLaren. He won the 1976 championship, but only just. Lauda was leading the championship by 3 points in the last race, but had to retire after torrential rain. That handed the championship to Hunt, who finished the race in the terrible weather, without knowing where he had placed or if he had clinched the title.

Lauda reclaimed the crown the next year in 1977, despite quitting the team with two races to go. The team calculated the position he needed to finish in to claim the title – 4th – at the US Grand Prix, and Lauda delivered and then joined Bernie Ecclestone’s Parmalat Brabham team.

In development terms, the cars began to sport air boxes above their heads to increase flows around the engines. Engineers changed their titles to designers, and began to increase their knowledge of aerodynamics. The cars began to take shape, using a streamlined body and undertray developments to the downforce and speed things up. There developments were called “ground effects” and impressed a lot of the drivers.

They were not without their problems though, because the new developments meant the setup of the car was incredibly important. One tiny degree the wrong way would mean the cars were unstable and ultimately not race worthy. F1 became a highly sophisticated balancing act. Eventually, the effects were banned in 1983, to make F1 more about driver skill and less about car setup.

That’s all for this episode of Sidepodcast’s History of F1, join me for the next instalment were we look at the 1980s.

F1 Guide (Part 4) - F1 Cars

Sidepodcast mini-series logo

Welcome to the Sidepodcast Guide to Formula 1.

A Formula 1 car is different to a regular road car. I mean, you know that already, because they make a lot more noise, they go a lot faster, and they look a lot different. But there’s more to it than that. There is an enormous amount of technology that goes into just getting an F1 car started, let alone maintaining it throughout a race.

The most important thing about a Formula 1 car is the aerodynamics. Hundreds of people make a living back at the factory, designing and testing new bits and pieces of the car to make it smoother through the air and thus faster on the track. What you basically need the F1 car to be is low to the ground, with as little disruption to the air flow as possible. Of course, at the high speeds the cars go, precautions need to be in place to stop the cars taking off, and that’s where the wings come in. Whereas aeroplane wings help get things skybound, F1 wings are designed to push the car into the ground.

The extra tenths that a good aero design can bring you will only be useful if you have the engine package in the car to go with it. With 7 gears, the engine and the car can get up to a top speed of 210mph, they produce about 800 brake horse power and can rev to 19,000rpm.

To control this much power, the drivers need some top technology at their fingertips. The steering wheel is small but holds an enormous amount of control, and is one of the most expensive items to be found on the car. Coming in at about $40,000, the wheel doesn’t just steer. It has paddle shift gear selection, can apply the pit lane speed limiter, contains an LCD screen with lap times, position and speed information displays, and lets the driver contact his crew with the radio. That’s why the steering wheel is the first thing a driver will grab for when he flies off the track.

A team has two drivers and each has their own car. The teams bring various spare parts with them to each race, front and back wings, replacement body parts, spare noses, and a spare engine. But if a car is beyond repair, then look no further than the T car – a spare for use in emergencies only.

All this equipment costs buckets and buckets of money. The majority of teams are backed by road car manufacturers, which means new technologies can be passed in either direction. The paddle shift gears was an F1 invention – and is now available as standard on some top range sports cars. It’s all supplemented by sponsors, and they are who really dictate what colours the cars are going to be. You can understand why Ferrari and Vodafone made such a great partnership, with their main brand colours both being red. With sponsor names scrawled across the bodywork, and all the nooks and crannies, angles and wings, F1 cars aren’t your normal kind of beauty. But they hold a certain fascination about them that will only grow the more you watch.

We’ve looked at all the good stuff about Formula 1, the next instalment will be about the rules.
