- clamprecht 12y agoNot only are they open wheel, but they have intentional downforce that exceeds the weight of the entire car.
- wmeredith 12y agoThey also have 600 horsepower and pass a gas station every 45 seconds :) Why compare?
- dripton 12y agoCurrent F1 rules do not allow in-race refueling. But, yeah, expensive purpose-built race cars have little in common with road cars.
- wmeredith 12y agoAh, I was thinking of Indy.
- threeseed 12y ago> But, yeah, expensive purpose-built race cars have little in common with road cars I wouldn't say little. Many F1 technologies have made it into production road cars and the future of the sport will see this technology sharing increase. That's why there was the big engine change last year. And it wouldn't surprise me if their split turbocharger design that was responsible for Mercedes success makes it into their road cars.
- sz4kerto 12y agoIt absolutely does make sense. F1 cars have high Cd because they need lots of downforce. An A6 does not need as high Cd as a sports car. So if a roadster's Cd goes down then the question arises: will it affect it's aerodynamic grip or not?
- tacos 12y agoSince you're asking a math question the answer is "yes of course." However having owned an Elise and driven a Tesla Roadster I will confirm that strapping the equivalent in weight of an entire F1 car in batteries to the bottom of one removes aerodynamic handling from the bigger equation at play. They're fun as hell and also uncomfortable as fuck. 400 miles is more of an endurance test for the driver than the power supply. (Also, loved every second inside both of them!)
