Porsche finally moving ahead with flat four engine

When Porsche released the first Boxster in 1996 and the first Cayman in 2005, the idea was to create an entry-level model for the German automaker's sports car range. The latest iterations of both closely related models, however, have begun to encroach dangerously on the 911's territory, particularly in their newest GTS specifications. That could be about to change, however, with the introduction of a four-cylinder engine for the compact mid-engined coupe and roadster.
According to Automotive News, Porsche is finally preparing to launch a new boxer four engine in the Boxster and Cayman, following years of speculation. The engine would be based on the same architecture as the company's famous flat six, but with two fewer cylinders to cut weight. Don't expect it to cut much in the way of performance, however: Porsche chief Matthias Muller indicates that the new engine could produce as much as 395 horsepower - significantly more than even the 340hp flat six in the Cayman GTS, suggesting that the engine could even find its way into the 911 as well.
It's no more clear which markets would get the four-cylinder engine, either. But wherever it is offered and in whichever form, it wouldn't be the first time we'd see a Porsche with a four-pot engine. Not by a long shot. Both the classic 912 and 356 were powered by boxer fours, as was the 914 - not to mention the 718 pictured above and the iconic 550 Spyder. The front-engined 924, 944 and 968 packed inline-four engines, but the last of those were discontinued in the 1990s. The prospect of a four-cylinder Boxster/Cayman has been rumored for many years now, most recently joined by the possibility of a four-pot Macan as well.

Porsche planning new 911 Speedster as 550 tribute

Some look at the emergence of a new Porsche 911 and see a car. But to Porsche engineers, it might as well be a reset button. Because every time a new 911 comes out, it sets off a tidal wave of new variants to follow, including convertibles, turbos, targas, GT3s... the works.
The next down the pipeline, though, could be one of the most desirable. That, according to German publication Auto Bild, will be a new 911 Speedster. When it arrives early in 2015, the special roadster will reportedly be limited to just 550 examples in tribute to the original 550 Spyder.
It'll reportedly have hidden door handles, a chopped-down windshield and a fabric top to be used only in case of emergency, manually disappearing below a carbon-fiber cowling. All of which makes it sounds as much like a bigger version of the Boxster Spyder as a successor to the last 911 Speedster (pictured above), and that's no bad thing at all.

Chris Harris pits Aston GT12 vs 911 GT3 RS vs McLaren 650S

The Geneva Motor Show is never lacking in exciting performance machinery. And this year was no exception. Our eyes, like those of Chris Harris, were drawn by two hardcore, track-focused versions of existing sports cars. Both wore the name GT3, and now Harris has brought them together for a supercar shootout. And he's thrown one more in for good measure. Those natural rivals are the Aston Martin Vantage GT12 and Porsche 911 GT3 RS, the latter manufacturer having pressed the former to drop the GT3 name to which it claims exclusive domain. There's a great deal that separates them, of course: one's got a V12 up front, the other a flat-six way in the back. But what binds them together is a common approach of taking an existing model, stripping it down, and tightening everything up to make it more of a weapon than a grand tourer. What that means in the Aston's case is a rather high price tag, much higher than that of the Porsche. But scarce demand and speculation on the open market have left British customers, at least, paying as much for the GT3 RS as for the limited-edition Aston. And that takes both into proper supercar territory. So to show what else that kind of money can get you, Monkey has brought along a McLaren. Not the similarly track-focused 675LT, but the standard 650S... Spider, no less, and with worn hard rubber. So which one performs best on the road? Which clocks the fastest lap time on the track? And which gets Harris' vote? You'll have to watch the video for yourself to find out, but it's well worth the 25 minutes of your lunch break.
