1980 Pennzoil IndyCar and Aerodynamic Evolution

last 5 years, we use... One of the Johnny Lightning engines is good, so we change it depending on which one we want to use that year. The 1978 one is a Lola. This one works too. I think we used it last year or the year before. This is the winner from 1980. We used it this year. We disassembled it in a similar way to the Lotus, down to the last detail. We removed each nut and bolt. Well, we restored almost everything that was metallic and had a finish. Well, I wouldn't call it a complete restoration, but it comes pretty close . The beautiful petrol yellow. It is? Yes. Wow. I didn't know Penske's pearly petrol yellow went back so far . You said yes. Is this from 1980? Yes. Well, this is the car Tim Richmond traveled in. Yes. And it was developed to reach the rear of the car with enormous diffusers. Well, this is from 1978 and this is the ground effect. If you look at the difference between the two cars, if you zoom in here, you can see the huge tunnels that use Bernoulli's principle to create that air that moves faster underneath the car compared to the air passing over it, turning the whole car into a wing. Now, when this car won, were there still cars on the grid that looked like it? Was this one of those cars that, when they arrived, made people say, "Damn, what have they done? We're screwed"?
