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.

Will the Mission E be the world's first must-have EV?

The Porsche Mission E concept was recently green-lit for production and has a tentative production date just before the end of the decade. With the recent onslaught of all-electric technology, the question remains: Which automaker will release the first must have all-electric EV? Tesla has clearly gained experience in testing the worldwide appetite for luxury, six-figure EVs, having sold its 100,000th vehicle in just three years and six months. But it remains to be seen if automakers can truly manufacture the ultimate green driving machine. Audi has shown its R8 e-tron but acknowledged that it will be produced in only limited quantities. On the other end of the spectrum, vehicles like the Chevy Bolt and BMW i8 are being produced for mass consumption, but will they satisfy the enthusiast who is looking for more than a commuter car? Tesla's Model S has certainly raised eyebrows and collected accolades with "ludicrous" level straight-line performance, but how well will the vehicle stand up to long-term ownership for enthusiasts? Porsche has dismissed any notions of autonomous driving in its vehicles, suggesting that it will try to stay close to its high-performance roots. This would seem to suggest that despite all the forecasted performance cred of the Mission E – 582 horsepower, 0–60 in 3.5 seconds, and a 310-mile range – potential buyers may not be getting the latest and greatest in gee-whiz-bang autonomous technology. And while Porsche has offered that future iterations of its 911 and 718 may in fact use hybrid-assisted drivetrains, the execution of a true, mass-produced, all-electric sports sedan remains to be seen. One thing is for certain, unlike start-ups like Tesla, the larger, more established manufacturers have larger budgets and more time to invest in R&D. Consumers have raised expectations from the more mature automakers in terms of reliability and the overall finish of their products. The arrival of the Mission E production car may introduce us to electric sports sedans that emphasize performance over efficiency while still eliminating its carbon footprint.

Porsche 911 to drop naturally aspirated six-cylinder engine

Rumors that the next-generation Porsche 911 will be completely divorced from naturally aspirated engines are picking up steam. Now, Road & Track is reporting that not only will the next 911, code-named 992, have a turbo-only engine lineup, but that the base Carrera and Carrera S will add the force-induced flat sixes as part of a facelift later this year. R&T only cites "sources familiar with the project," which claim that turbocharged flat-sixes will be at the core of the 992's engine range, alongside a plug-in-hybrid model. A four-cylinder 911 remains unlikely. What's most surprising, though, is how soon Porsche will introduce a turbocharged base-car lineup. Road & Track claims the blown flat-sixes will be added as part of a facelift coming before year's end. Perhaps unwilling to risk the further ire of purists, the current car's seven-speed manual transmission will continue to be sold, alongside the company's excellent PDK automatic transmission. As for when this facelift will happen, the 2015 Frankfurt Motor Show in September seems like the most obvious date.
