2016 Porsche 911 GT3 RS prowls into Geneva with biggest NA engine in the 911 range [w/video]

We've been waiting for the debut of this road-going and race-ready Porsche 911 GT3 RS for quite some time now. As is typical for high-profile sports machines, the new 911 has been foreshadowed with spy shots and information leaks aplenty, all pointing to this grand day at Geneva. Here she is. Just a glance at the duct-sliced bodywork and massive rear wing will tell you that this Porsche means business, but let's look at its bona fides. The heart of the matter, under that short rear deck, is the largest-displacement and most powerful naturally aspirated engine in the 911 family, with 500 horsepower and 338 pound-feet of torque developed by the 4.0-liter flat-six. That hoss of an engine is mated to a newly developed version of Porsche's PDK dual-clutch gearbox – with functions such as "paddle neutral" that effectively works like depressing the clutch on a standard manual, and a Pit Speed button for on the track. Working in concert, engine and trans allow the GT3 RS to sprint to 60 miles per hour in 3.1 seconds, hit a quarter mile in 11.2, and lap the Nurburgring Nordschleife in just seven minutes, 20 seconds. (That 'Ring time makes it the fastest current 911 around the benchmark course, and five seconds faster than the current 911 GT3 – so quick.) Weight has been saved via exotic materials; the car sports a magnesium roof and carbon fiber for the trunk and engine lids. Overall the RS is 22 pounds lighter than the GT3, but also boasts a lower center of gravity. As we said at the top, there's a wide, low and aggressive body kit on the GT3 RS, all engineered with racing performance in mind. That huge rear wing is balanced in the front by a deep chin spoiler, and the front wheel arches have been punctuated with vents that help to increase downforce on the front axle. The roll cage is the most obvious interior modification to let one know that this is a racing tool, but Porsche has also slathered the space in Alcantara and installed carbon-fiber bucket seats (based on those found in the 918 Spyder) to drive the point home. The cost of such racing glory will be steep at $175,900 plus a $995 destination charge, but not out of the scope of the current ask for the 911 range, when you consider that a Turbo S runs over $180k. Look for 911 GT3 RS deliveries to start in July of this year in the US, and for track days to be more competitive for the addition.

Porsche offering new tire option for Carrera GT

Let's face it: finding new tires for older cars can be challenging if tire manufacturers have stopped carrying the right sizes (this writer went through Hell to find a set of 205/60-13s). But what about tires for low-volume supercars, which use sizes that often won't fit on high-volume production vehicles? The Porsche Carrera GT isn't that old and tires are still available in the correct sizes, but the German automaker has shown its support of keeping them on the road by working with Michelin to give owners yet another tire option. Enter the Carrera GT-specific Pilot Super Sport.
It's common knowledge that tires are one of the most important pieces of the performance puzzle, and Porsche claims that the PSS tires, sized 265/35ZR-19 front and 335/30ZR-20 with Porsche's "N0" rating, will improve the Carrera GT's handling and stability all the way up to its claimed top speed of 205 miles per hour. That's important for a car with razor-sharp handling characteristics. They'll also net drivers a 10-percent increase in fuel economy on regular roads and up to 20 percent on racetracks, Porsche says.
The PSSs use cutting-edge tire technology to harness the Carrera GT's 610-horsepower. They have a dual-compound tread that's different from the inside of the tire to the outside, which, Porsche says, helps steering precision and increases maximum grip. Aramid fibers, which are lightweight but just as strong as steel, are used in the tire's belt to reduce unsprung weight.

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.
