'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.

McLaren P1 squares off against Porsche 918 in Evo track battle

Evo's side-by-side comparison of the McLaren P1 against the Porsche 918 Spyder isn't the first time we've seen England and Germany's ultimate automotive weapons sized up together; last month, Autocar tested them over the standing mile, with a Ducati 1199 Superleggera playing the joker. Evo throws a few curves at its test, though, taking the supercars to Anglesey Circuit in Wales to see which will lay down the fastest lap time with scribe Jethro Bovington at the wheel. In case the numbers haven't yet been seared into your memory, while both are assisted by electric motors, the 3,069-pound, rear-wheel drive P1 gets on with 903 horsepower and 664 pound-feet from a 3.8-liter, twin-turbocharged V8. The 3,750-pound, all-wheel-drive 918 Spyder does its job with 795 hp and 575 lb-ft surging out of a naturally aspirated, 4.6-liter V8. We're not told know which circuit layout he uses for the test, but both cars comfortably eclipse the mark set by the fastest coupe Evo's driven around it so far, the Ferrari 458 Speciale. Then, in an epilogue occasioned by a tire change, one of the supercars comfortably eclipses its own time again, before Bovington declares one the master of the track and the other the ruler of the street. Enjoy finding out which is which in the video above.

Your guide to vehicle subscription services

They might be extremely limited in scope because of location availability, but vehicle subscription services are a growing trend that most luxury manufacturers are jumping on. Plans are expensive, but you're paying for much more than just the car typically. We highlighted four of the larger plans with a few more listed at the end. Care by Volvo Volvo launched its subscription service last year with its brand-new XC40. It was the only vehicle available for a time, but subscribers can now get an S60 sedan as well. Subscriptions are for two years, with the monthly price including insurance, a concierge service, wear-and-tear item replacements and all maintenance. You'll be able to drive 15,000 miles per year with whichever Volvo you choose, and although there are no options to extend that mileage, you can swap cars after a year. Pricing for the XC40 is $650 per month in base trim, while an S60 can be as expensive as $850 for the R-Design. Volvo's plan is to offer more cars soon through the service, but it's relatively limited compared to others right now. Porsche Passport Porsche has two levels in its subscription service: Launch and Accelerate. Launch will cost $2,000 per month and give you access to the Cayman, Boxster, Macan and Cayenne. All of those but the Cayenne can be had in "S" trim as well. Accelerate is where the fun really starts. For $3,000 per month you can choose from a fleet of 911s, including the S, 4S, Cabriolet and Cabriolet S. If those aren't enough, you can also get the Panamera 4S, Macan GTS and Cayenne S. There are no mileage limits and you can change vehicles as often as you'd like. Also included in the price is insurance, repairs, detailing and any maintenance. It might be extremely expensive and limited to Atlanta only, but this subscription service is second-to-none for what you get. Audi Select Audi just launched its subscription car service, and it's offered in one version for a flat fee of $1,395 per month. For that you'll have access to five different cars including the A4, S5 Coupe, A5 Cabriolet, Q5, and Q7. Not a bad range of vehicles, but it would've been neat to see the recently updated A7 in there too. Maybe in time. Like the others, insurance and maintenance are wrapped up in the price. Audi is allowing for unlimited miles and two car swaps per month here. In addition to that, you'll get two days of free rentals through Audi's Silvercar rental agency should you go on a trip.
