Dramatic images of cars travelling similarities between the two eras. In the 1990s backwards and taking off have been beamed there was an all-out engine war between around the internet and television networks Honda, Ford, Chevrolet, Toyota and Mercedes. and the uproar has been deafening. From within The engine regulations worked and the value the IndyCar paddock, however, there is silence of the series was at its peak at the time that and no one from the technical teams are talking Racecar Engineering started its extensive on the record as the world demands answers, coverage. Penske, Lola, Swift and Eagle were and surely there are answers to be had. Are the also having at it in a chassis war so there was aero kits to blame for these big accidents? That’s nothing wrong in terms of competition. Today’s certainly one that IndyCar cannot yet answer IndyCar is a different world, with a spec chassis as there is no valid data or proper investigation and for the first time in a long time, technical into each individual accident. Could the innovation with the competing manufacturers accidents have been avoided? Again, who Chevrolet and Honda allowed to produce new can answer that one without first conclusively aero kits (see Racecar Engineering V25N5). The establishing the common factor between the introduction of the new kits has not been a accidents? What IndyCar can do is release the smooth process, with limits put on the amount details that they have. They know the speeds, of development in order to avoid having to the conditions, the forces running through redesign the entire car, but in practice for the the suspension, they know the basic details at Indianapolis 500, four cars have crashed heavily. the start, during and post accident and The fact that the race is going ahead no doubt will be poring over the data at length suggests that IndyCar has a grip on the situation ahead of the big race. What it cannot afford and is prepared to push ahead with the to do is to have large accidents on a global competition, which in itself is an encouraging media platform, much less even if a driver or sign. There are reasons for the crashes, but spectator is hurt or killed. as one engineer here put it, you cannot rule It seems clear that there is some element or out old-fashioned co-incidence. Back in 1998, elements that have led to the crashes, but what ChampCar introduced the Handford Device, they are will take time to find. Is it the speed, a new rear wing design that was supposed to the aero kits, the tyres, the cars, the part-lifing slow the cars by 20mph following record speeds brought on by rising costs of competition? the previous year. What happened was that the Racing is still about competition, and drivers complained that they were running too competetition equals speed. Managing speed close, and questioned whether nor not single is a complicated business, and the challenges seat racing should be like that. It was a classic facing IndyCar are precisely the same as those case of the law of unintended consequence facing the sport in the 1990s. 2 www.racecar-engineering.com INDYCAR SUPPLEMENT Contents 18 Penske PC22 Chevrolet 58 Menard vs Honda vs Ford vs Mercedes 70 Royal with cheese Roger’s new toy in 1992 The 1995 Indy 500 power struggle Honda’s Japanese-American race engine featured all the big bangers became the prince of the power revolution in 1996 30 Clash of titans Cosworth vs Chevrolet at Indy 1993 64 Indy Infi niti Nissan stepped into IRL against 79 Handford Device Chevrolet’s Oldsmobile brand ChampCar’s solution to slowing cars led Lola T94/00 Ford XB 42 to an unexpected result Robby Gordon’s ride for 1993 67 Aurora powerplant IRL takes its own route and Racecar 84 Class of 1999 Penske P23 Mercedes-Benz 46 covered the split, and the consequence All you need to know about the golden Landmark partnership for the two from a technology point of view year of ChampCar racing companies as Mercedes stepped into the fray for the rst time INDYCAR SUPPLEMENT www.racecar-engineering.com 3 DOWNLOAD The Racecar Engineering App Quality Wine Sales l London Merchant A fresh approach to the fine wine market This 1982 La Mission Haut Brion is a great wine with amazing depth www.vinandco.co.uk Vin and Co Email: [email protected] • Tel: +44 (0) 345 956 9699 Vin and Co 45 Pont St l Knightsbridge l London SW1X 0BD GO DIGITAL with RACECAR ENGINEERING ON YOUR TABLET Subscribe to the digital edition for fast and easy access to Racecar Engineering anytime, anywhere.
