Chris Harris hits the track in the Porsche 911 GT3 RS

One of the wonderful things about Chris Harris on Cars is the enthusiasm that the host brings to the screen. Granted, it would be hard not to enjoy a day driving around in a supercar that you don't own. Still, Harris brings a sense that he knows how rare these opportunities are and relishes them. In his latest look at the two sides of the latest Porsche 911 GT3 RS, you can tell this guy is having a lot of fun. The GT3 RS is a 500-horsepower, track-focused weapon, but it's expected to drive to and away from the circuit after a day of laps. Therefore, Harris decides to evaluate the attributes of this Porsche in both environments. On the road, he sweeps an orange example over some beautifully, undulating German backroads but keeps things rather tidy. However, in the latter half of the video, he arrives at the Weissach test track for a go in a purple RS. There, he really lets the rear hang out.

Pininfarina teases its Tesla- and Bugatti-baiting EV supercar

Pininfarina isn't being bashful when it comes to getting into the car business. The Italian design house has revealed a sketch of the PF0 Concept, an electric supercar aimed directly at the world's fastest and most expensive vehicles. With upward of 1,000 horsepower, along with an expected price in the millions of dollars, this extreme EV is meant as a calling card for Pininfarina's upcoming range of electric cars and SUVs. So should the likes of Tesla, Porsche, Ferrari, Bugatti and Lamborghini be worried? Pininfarina might be new to building its own cars, but the company has many decades of experience designing and engineering some of the most desirable cars of all time — including many of the finest supercars to have worn a Ferrari badge on their nose. As we reported earlier this year, Pininfarina has teamed with Indian auto manufacturer, Mahindra, to develop a range of high-end EVs. With this roughly $500 million investment, not to mention some engineering help from Croatian supercar manufacturer, Rimac, Pininfarina aims to start high. The company will first introduce a hypercar, based on the PF0 Concept, within two years, then bring along a range of more affordable electric cars and SUVs. These will more directly take on the likes of Porsche Cayenne, Lamborghini Urus, and Tesla Model X. So yes, if you're in the business of building expensive cars, especially ones with a lot of batteries positioned inside them, Pininfarina's plans for the PF0 (that's a zero, not the letter "O," by the way) should make you sit up and take notice. "Automobili Pininfarina is a pioneering new business created to service the most discerning clients in the world," said Michael Perschke, CEO for Automobili Pininfarina. "Our product portfolio will launch with an innovative, zero-emissions hypercar that represents the progression we aim to make at the pinnacle of the luxury and sports car market." According to its press release, Pininfarina is currently presenting its "business and product plans to prospective retailer partners, clients and media in New York this week." After its tour of the Big Apple, look for Pininfarina to officially reveal the PF0 Concept during Monterey Car Week in August.

'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.
