Autocar pits Porsche 911 Turbo S against Formula 4 racer

There is a long-running argument among performance car fans: power vs. weight. In one corner you get cars generally with small engines making modest numbers but able to corner like they are telepathic, and in the other there are big thumping mills that are rocketships in a straight line but lumber in the turns. Autocar takes an interesting look this continuum in a recent video pitting a 552-hp Porsche 911 Turbo S against a 185-hp Formula 4 racecar. It hopes to find whether the Porsche's huge power advantage is enough to defeat the better grip and aero offered by the nimble racer.
There's no doubt that the Porsche is an utterly fantastic road car. The 911 Turbo looks mean with all of those intakes to suck in cool air, and it backs up the posture with huge amounts of grip available thanks to its all-wheel drive-system. However, at 3,538 pounds, it's a bit of a porker compared to the 1,135-pound Formula 4 car. The open-wheel car boasts just a 2.0-liter naturally aspirated four-cylinder from Ford and a six-speed sequential-manual gearbox, but it has loads of downforce to make up for it.
It shouldn't be a surprise that the formula car wins in the corners. After all, that's what it's made for. So do you think the massive horsepower superiority of the Porsche is enough to even the playing field? Scroll down to watch the video and find out, and even if you're not curious of the winner the 911 does some mean powerslides.

'Faster. Farther.' dives into the history of Porsche racing tech

No doubt, Porsche has produced some of the best endurance racecars around, such as the turbocharged, slant-nose 935 of the 1970s and the ground-effects-enhanced 956 and 962 of the 1980s. But the company's most famous racecar, its first overall winner at the 24 Hours of Le Mans, was the 917.
The 917 embodied many of Porsche's technological achievements up to that point, such as the company's first 12- and 16-cylinder engines (the flat-16 was never used in competition), fiberglass bodies that implemented early aerodynamic practices and the use of new, exotic materials, such as magnesium and titanium.
The racecar was commissioned by the head of Porsche Motorsports, Ferdinand Piëch, to win overall at the 24 Hours of Le Mans in 1970, after he realized a loophole in the rules that allowed cars to compete with engines up to five liters in the Sport category if they were also production models. Piëch saw opportunity: the top prototype class was restricted to three liters; the production minimum to compete in Sport was 25 cars. And so, with much effort, Porsche assembled 25 "production" 4.5-liter 917s and had them parked in a neat line for the race inspectors to verify their legitimacy. It didn't take long before people realized the new Porsches were much faster than the prototype racers, with a top speed approaching 250 miles per hour.

Take a POV hot lap in the Porsche 918 Spyder

That title about says it all. This is a hot lap of the Circuit of the Americas in Austin, TX, with Porsche Works Driver Patrick Long at the wheel of a Porsche 918 Spyder. The camera is basically showing us everything that Long sees, making this not just one of the coolest 918 videos we've seen, but also one of the neatest laps of CoTA.
As Long peers through the bends, so will you. You'll see him fight the wheel, and find out just how difficult it is to hustle this hybrid hypercar around a world-class track at speed. It's pretty darn entertaining. There are also a few scattered shots of the 918's exterior just to break up the interior awesomeness, although we aren't exactly complaining about those. Take a look below for the short video from Porsche.
