Koenigsegg is now a well established manufacturer of hyper cars. They famously built "the only car that defeated the Stig" since the CCX spun out while he was driving it for a lap time back in 2006. Despite the hypercar performance, Koenigsegg also prides itself in luxury and exquisite attention to detail. It is now also famous for building the hybrid Regera hypercar and the One:1; the first production car with a power to weight ratio of 1:1 hp per kg (it makes 1 MW/MegaWatt of power, prompting Koenigsegg to call it the first Megacar with a straight face). But this post isn't about all of Koenigsegg's fascinating cars. No, it's about only the Regera. Or the Regera hybrid technology, rather. Koenigsegg just sold 20% of its parent company for €150 million (~$171 million USD) to NEVS. They also started a joint venture together where NEVS is contributing $150 million USD (~ €132 million) for a 65% stake in the joint venture. Koenigsegg is taking a 35% stake...
I've been a huge fan of Michelin PSS tires and exclusively bought them for the Mustang over the last four years. So how did I end up here? This year, I was hugely interested in trying an "R-comp" tire. I had my eyes set on Bridgestone Potenza RE-71R's for two simple reasons: price and reputation. Although not a true "R-comp" tire on paper, it performs like one by the account of every single test and review I've read (down to wear rates...). They seem like they're easily the most affordable (from a big brand) R-comp tire and combine that with a reputation for having tons of grip, it was an easy top contender. I had my concerns, though. For one, I'm told and have read that they are an autox tire, not really designed for high speed, pressure, and temps associated with open track. For another, the Mustang is a heavy car (as far as track cars are concerned) being roughly 3,800 lb. (including driver), which will amplify the unwanted open track load...
