Porsche testing four-cylinder Boxster at the N?rburgring

Porsche recently introduced a four-cylinder version of the new Macan for markets outside of North America, carrying Zuffenhausen's first four-pot since the 968 ended its production run the better part of two decades ago. But you can bet the compact crossover won't be the only Porsche to get the four banger before all's said and done. These spy shots, we're told, are evidence of just that.
Spotted undergoing testing at the Nürburgring (where else), this modified Boxster, our spy photographers tell us, sounds more like a four-cylinder engine than the flat six that's powered (in displacements ranging from 2.5 liters to 3.4) every version of the little roadster since its introduction in 1996, the year after the last four-cylinder Porsche ended production.
The test mule is also wearing modified wheel arches and aerodynamic aids under the bumpers, front and rear. Just what they're doing there we're not sure, but we'll probably find out sooner or later.

Can a Corvette really be compared to a 911 with options costing more than the Chevy?

In this latest video from Drive, Chris Harris asks straight away, "Can you still compare a base Corvette to a Porsche Carerra?" That's an particularly interesting question in this film, as the 911 in question is a 400-horsepower Carrera S model that's been fitted with $60,000 in options. Base price of a Corvette Stingray? $51,995. Harris' tester features an automatic and some other goodies that push it right up to that $60,000 range. So yes, the options on the Porsche cost as much as this entire 460-hp Chevrolet.
Harris stresses that this isn't a full review, but he does exercise both cars in a more composed manner before reverting to his traditionally exuberant driving style. The impressions are, as always, spot on, with Harris favoring the pointy nature and V8 power of the Stingray, while enjoying the gearbox (Porsche's exceptional PDK transmission) and just about everything else on the 911.
Take a look below for the latest video from Drive, and let us know if you agree with Mr. Harris' views on these two sports cars.

Porsche 919 Hybrid revives Porsche's factory Le Mans efforts

After months of teasing with camouflaged testers, Porsche has finally unveiled its prototype entry for the 2014 World Endurance Championship, the 919 Hybrid. Porsche, you may recall, hasn't had campaigned a factory team at Le Mans in years, so the 919 is nothing less than their recommitment to endurance racing.
Combining a 2.0-liter V4 (yes, a V4) that revs to 9,000 rpm, the 919 produces around 500 horsepower with a pair of energy recovery systems. The first system recovers the heat energy from exhaust gasses as they pass through an electrical generator, while the second system is a bit more familiar. Using a setup similar to what is found on the production 918 Spyder, a generator on the front axle recovers kinetic energy from the brakes, which is subsequently stored in a battery system. That power can then be sent to the front wheels at the driver's command, effectively turning the 919 into an all-wheel-drive racecar.
Despite these various forms of motivation, Porsche doesn't claim to be seeking outright power supremacy, with Chairman Matthias Müller saying, "In 2014, it will not be the fastest car that wins the World Endurance Championship series and the 24 hours of Le Mans, rather it will be the car that goes the furthest with a defined amount of energy. And it is precisely this challenge that carmakers must overcome. The 919 Hybrid is our fastest mobile research laboratory and the most complex race car that Porsche has ever built."
