'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.

Meet the new Porsche 718 Boxster and Boxster S

The rumors were mostly true. Porsche had already confirmed that the Boxster and Caymans would receive a "718" appended to their badges, in honor of their famous mid-engined racecar of the 1950s and '60s, but the mechanical details were left up in the air. We were almost certain both would be powered by turbocharged flat-fours of a couple of displacements and outputs, and now we can confirm that this is the case. Porsche has revealed the official specs for the 718 Boxster, which will go on sale in Europe this April. The biggest news concerns the flat-fours. The regular 718 Boxster will get a 2.0-liter, turbocharged flat-four producing 300 hp. The 718 Boxster S will get an extra half-liter of displacement and a variable-geometry turbocharger to produce a total of 350 hp. This represents a 35 hp gain over the current Boxster and Boxster S, respectively. Porsche also claims the turbo fours improve fuel economy by around 13 percent. By the NEDC European test cycle, the 2.0-liter gets roughly 34 mpg and the 2.5 gets 32 mpg, although rest assured that EPA test results will yield different numbers than the optimistic European test. Torque gains with the new boxer fours are significant. The 2.0-liter gains 74 lb-ft of torque for a total of 280 lb-ft from 1,950 to 4,500 RPM. The 2.5 gains less, 43 lb-ft, for a total of 309 lb-ft over the same rev range. The extra torque and wide torque band make the 718 Boxster quicker to 60 mph, at least when equipped with the PDK gearbox and the Sport Chrono Package. The 2.0-liter car does the deed in 4.5 seconds, a 0.7-second improvement, and the 2.5-liter car is claimed to hit 60 mph in 4.0 seconds, a 0.5-second improvement. 2016 Porsche 718 Boxster View 11 Photos Inside, a new dash houses the latest Porsche Communication Management infotainment system with a touchscreen, included on all 718 Boxsters as standard – although nav is an optional extra. The buttonless, capacitive-touch center stack we just spied on the next Panamera does not make it inside the 718 Boxster, which makes do with a very similar button layout to the current car. Both cars will come with a six-speed manual as standard, which is great news, and a PDK will be optional for both. Porsche also claims to have made the electrically-assisted steering more direct, and retuned the suspension. An optional PASM package lowers the car by 0.4 inches while providing the benefits of active dampers. From a styling standpoint, this is an evolution of the current theme.

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.
