Porsche Cayenne diesel V8 may not be long for this world

Goodbye, Porsche Cayenne V8 Diesel. We hardly knew ye. Nor did the Europeans, apparently. Porsche's V8 oil burner is still on the European model list for the Cayenne SUV, but the mill won't go through the likely pricey process of being updated to adhere to new and stricter European emissions standards, Just-Auto says. A Porsche spokesman confirmed to the publication that it's a fairly complicated process to update the diesel V8 to be so-called "Euro-6 compliant." With Cayenne diesels selling in relatively low volumes anyways, the German automaker might just dump the V8 diesel altogether, as it'd be quite cost-ineffective to make the necessary upgrades. The V8 diesel was a 4.1-liter engine that delivered 385 horsepower in addition to what sounds like a little too much exhaust for European clean-air regulators. While that's a pretty powerful profile, the most recent gas-powered V8 for the Cayenne delivers about 570 horsepower, so the diesel engine won't likely be missed by European auto enthusiasts. Besides, there's still the V6 diesel that's also sold in the US. That's a 4,800-pound beast that moves from 0 to 60 miles per hour in about seven seconds and gets a relatively (for diesels) modest 20 miles per gallon city. For those who are curious, Autoblog's First Drive review of that model can be found here.

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:

Porsche planning Cayman GT4 racer

To say that Porsche is big in racing is like saying that Warren Buffett dabbles in mergers and acquisitions. But while it fields the 919 Hybrid at Le Mans and in the FIA World Endurance Championship, the bulk of its racing activities are undertaken by private teams that buy customer racecars from the factory. Those in turn are largely based on the 911, but the latest intel from the motor racing world indicates that Zuffenhausen is planning a more accessible customer race car.
The new, more affordable competition car is to be based on the Cayman and built to GT4 specifications, slotting in below the 911-based GT3 Cup, GT3 R and RSR. Autosport reports that Porsche has already developed a prototype and will shortly commence testing. Details are scarce at the moment, but the Cayman GT4 would seem to compete against the likes of the Aston Martin Vantage N24, Nissan 370Z Nismo GT4 and Maserati GranTurismo MC. It will also likely help Porsche foster enthusiasm for a potential road version that's already been spotted undergoing testing. Previous GT4 racing conversions of the Cayman, like the one pictured above, were carried out by third-party racing constructors not recognized by the factory.
Porsche may not be the only one showing interest in the category, however. BMW is said to similarly be considering a GT4-spec version of its M235i Racing model to compete in the same class, taking the place of the defunct M3 GT4 as the Bavarian marque's entry-level customer racing car.
