New Porsche 4-cyl engines to range from 1.6L to 2.5L

Recent rumors of a turbocharged, flat-four-engine from Porsche for the Boxster (pictured testing above), Cayman and maybe other models go back over a year. The latest scuttlebutt indicates that there could be three variants on the horizon with 1.6-, 2.0- and 2.5-liter displacements and power as high as 360 horsepower.
Car magazine in the UK claims to have access to the specifications for the project and thinks the 2.0- and 2.5-liter versions are guaranteed for production for the Boxster and Cayman. However, it believes a question mark still looms over the 210-hp 1.6L because the engine would go into a new, smaller sports car that still doesn't have a green light for production.
Regardless of displacement, the new fours would be turbocharged and direct-injected. The 2.0-liter would produce around 286 hp and 295 pound-feet of torque, and the 2.5-liter would make about 360 hp and 347 lb-ft. Earlier reports pegged some parts sharing with the current flat-six.

'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.

Porsche revisits the 911's dirty side with rally history film

It might not be a coincidence that there are rumors of Porsche revealing a safari version of the 911 at April's Beijing Motor Show, just as the Dakar Rally is about to begin. Adding fuel to the dusty desert fire is a just-released official video of Jeff Zwart driving the Porsche 953 that Jacky Ickx drove to victory in the 1984 edition of the race.
In the video, the seven-time Pikes Peak International Hill Climb winner talks about how he grew up with the 911; it wasn't only the car he learned to drive in, it was his choice of racecar no matter whether the course was tarmac or the dirty stuff.
You can decide for yourself if these recent events are mere coincidence while you enjoy the 953's exhaust note in the video below. If you've got the time to see the 953 during its race-conquering drive and find out what the ersatz Paris-Dakar Rally used to be, we've also included a broadcast of that 1984 race below as well. Fast-forward to 19:44 to see the Porsches cross the open dessert and 29:09 to watch one of them tackle the dunes.
