Is Porsche planning a GT5?

A trademark application filed in Europe suggests Porsche could be planning a GT5 model to slot at the bottom of its track-focused sports car lineup. The German automaker's GT skunkworks division in Weissach earned its reputation with enthusiasts producing the GT3 and GT3 RS versions of the 911, and previously offered GT2 and even GT1 models as well (although the latter was a limited homologation special). It recently extended itself slightly downmarket with the launch of the Cayman GT4, but this trademark application – already reportedly accepted in Germany and currently being reviewed by the European office – suggests an even more accessible model could be on its way, Autocar reports. Just what form a GT5 would take, however, remains a mystery. The numerical progression would suggest that Porsche is planning a hardcore version of an even smaller sports car, if such a project ever got off the ground to slot in below the Boxster and Cayman. Given that the 911 has bred both GT2 and GT3 versions, Weissach could alternatively be planning an additional GT version of the Cayman, or planning a hardcore version of the Boxster. The prospect of a GT5 version of the Macan, Cayenne, or Panamera seems unlikely as the alphanumeric designation has never been applied to anything other than a two-door coupe, but then we never really know what the future will bring: Before 2002 Porsche had never done anything with more than two doors altogether. These designations are typically borrowed from their corresponding racing class, and of course there is no GT5 category. But then most of these racing classes have been amalgamated into GT3 anyway, unless Porsche is planning on using the name for its own entry-level spec racing series. But at this point we're just spitballing. It's just as likely that the company has simply filed the trademark application to keep its options open for the future. Related Video:

Bisimoto's 911 and Honda Odyssey each pack 1,000 hp

There aren't a lot of vehicles on the road that pack a thousand horsepower. The Bugatti Veyron and McLaren P1 are in rare company, but there have been a handful of aftermarket tuners that have managed to extract that much power out of lesser vehicles. Bisimoto is responsible for more than its fair share, so Matt Farah and the team at Drive stopped by the workshop in Southern California to check out the craftsmanship for the latest episode of Tuned. What they found is two vehicles with that astronomical four-figure output that otherwise couldn't be more different from each other. First up is the vintage, stripped-out 911 that company founder Bisi Ezerioha built for himself. It's based on a 1976 Porsche 911 Carrera with a widebody kit and a pair of turbochargers hanging off the back. The result is that thousand-horsepower output and, as Farah found out, one of the scariest, hairiest, and squirliest automobiles ever devised. As if that weren't enough, there's a thousand-horsepower minivan on the docket, too. This one is based on a Honda Odyssey, rebuilt on an air suspension and a six-speed manual gearbox conversion out of an Acura TL. And of course the engine's been tuned to deliver that headline output figure. Honda and Bisimoto showcased the vehicle at the SEMA show a couple of years ago, where Farah says he didn't think it could possibly hold together. But as he discovered in the video above, it actually does, and accelerates with tenacity... and plenty of room for the kids.

Porsche announces plan to replace 911 GT3 engines

About a month back, we reported that Porsche was suspending delivery of its 911 GT3 due to reported incidents of the engine bursting into flames. A few days later, Porsche told owners of the new track-ready models not to drive their cars and had their local dealers pick up the cars in question. Just a couple of days ago, we reported that Porsche was working on a fix, and now we have the official details.
Following an internal investigation prompted by two such incidents, Porsche has confirmed that is has identified the problem as resulting "from a loosened screw joint on the connecting rod." The loose connecting rod, Porsche found, damaged the crankcase, which in turn resulted in oil leaking and then - in at least two cases - igniting.
Our source is unaware of Porsche being contacted by GT3 owners concerned about the impact of a replacement engine on their car's collectibility or resale value.
