Porsche Cayman GT4 looks sexy, rapid in the nude

Porsche doesn't officially have a name for its more hardcore version of the Cayman, yet. The speculation is that the coupe is called the GT4 as a little brother to the 911 GT3. However, the German sports car maker apparently is not interested in keeping the model's looks much of a secret because these latest shots show it without a hint of camouflage to speak of. The GT4 reportedly takes the GT3's ethos of more power, less weight and stickier-than-glue handling and brings it all to the Cayman. As these photos show, there's a much lower air dam up front with a cooling vent at the tip of the hood. Larger wheels are another obvious addition and are likely shod with some very sticky rubber. At the back, there's a double spoiler combining a wing and a ducktail. The power and gearbox for the GT4 remains a mystery, though. The rumor is that it uses a tuned version of the 3.4-liter flat-six in the Cayman S and GTS to make between 370 and 400 horsepower. A similar overhaul of the Boxster might be on the way, as well. A version of the convertible wearing some of the Cayman GT4's goodies was recently spotted testing. That one even had a manual transmission to make the prospects behind the wheel even more exciting.

911 beware! Porsche testing new top-trim Boxster

The Boxster and Cayman are like the scrappy siblings compared to their star brother – the Porsche 911. And now it looks like the rivalry is about to get even more serious, as our spies have captured this hotted-up Boxster doing some winter testing. We've already seen Porsche evaluating a higher-performance version of the Cayman, rumored to be called the GT4. It would reportedly offer a taste of the thrills of the 911 GT3, but at a lower price. The coupe appears to have a convertible twin in this Boxster prototype. The biggest giveaway of their possible relationship is the shared front bumper with larger intakes and an extra opening at the tip of the hood. Although, this one lacks the Cayman's big, rear spoiler in favor of a smaller decklid unit. The good news for fans of shifting for themselves is that this tester is fitted with a manual transmission, according to our spies. Being a prototype, though, there's no guarantee that the gearbox makes it to production. At least in Cayman trim, these higher performance models might use a tuned version of the 3.4-liter flat-six with between 370 and 400 horsepower. Though, an earlier rumor suggested that a turbocharged four-cylinder could sit behind the driver. Until we know for sure, glance at the gallery to see a Porsche that might try to challenge its big brother.

Porsche purists, look away: This 911 is powered by Hyundai

Bisimoto appears to be putting together a Hyundai V6-powered Porsche 911. While the experiment reminds us of a project from earlier this year, in which Ryan Tuerck dropped a Ferrari V8 into Toyota GT86, this one's a bit different. Bisimoto has a history of creating some truly insane automobiles, usually with Veyron-menacing power levels. In fact, the tuning company built multiple 1,000 horsepower machines, including a 1976 Porsche 911 and a 2013 Hyundai Genesis Coupe, not to mention a few other Hyundais with oodles of power. So it seems Bisimoto has decided to combine the company's experience with both marque's into one machine with this 1977 Porsche 911. This content is hosted by a third party.

No specific details about the engine were given, but a "hyundaiusa" tag, some helpful hints from Instagram commenters and some diligent Google image searching by Autoblog staff members seem to show that this is a Hyundai Lambda series V6. It also appears to be a version from a car with a transverse layout, which would make it easier to fit in the 911's traditional engine location. What we do know is that the build will be completed in time for the SEMA show, and we look forward to seeing the finished Franken-Porsche. The same probably can't be said for Porsche purists though.
