It seems as though Porsche itself was caught off guard by the announcement of this special-edition 911. The company had shut down the line that would normally build the engine for a car like this, so, when the brass decided they needed one more final 997, Porsche had to restart production.

The GT3 is, of course, the purest 911, which makes a GT3 derivative the appropriate final send-off for the 997 before the arrival of the 991. Porsche launched the first GT3, in 1999, to counter claims that the 911 had gone soft, what with the 996’s larger body and water-cooled engine. Some in the marketing department expected the company to sell a few hundred—or a thousand at the most—but Porsche has since sold around 15,000 GT3s. That’s even more surprising when you consider the fact that the GT3 has been available only sporadically.

The more extreme GT3 is the RS—Porsche says that 85 percent of RS buyers take their cars to the track regularly. And now Porsche is topping that with the GT3 RS 4.0, which is lighter, more powerful, and handles even better. That 4.0 in the car’s title refers to the displacement of its engine. While other GT3s use a 3.8-liter flat-six, the 4.0 borrows the upsized engine from the track-only GT3 R and RSR. The bump in displacement results from a longer stroke, as Porsche could not increase cylinder bore. Titanium connecting rods and a single-mass flywheel shave a few pounds, but all other changes relative to the GT3’s 3.8-liter six enhance airflow. It gets a higher-flow air filter, a modified intake manifold with shorter runners, and a less-restrictive exhaust—the last of which reduces back pressure and amps up the noise in equal measure. The result is an increase in output from 450 hp to 500 hp, with torque edging from 317 lb-ft up to 339.



Three Pedals, One Clutch
Porsche does not offer its PDK dual-clutch transmission in any GT3, and that stays true for the 4.0. While the company claims the PDK is superior to a manual box in a more civilized context, keeping it out of the GT3 family seems like tacit admission that there is nothing like the control offered by a manual transmission. (Even one with seven speeds, which we’ve confirmed Porsche will offer in the next-generation 911.) Additionally, the traditional manual is lighter than the PDK transmission, and it enables experts to initiate drifts more smoothly by playing with the clutch.

This test drive takes place in the tranquil village of Hohenstein-Ödenwaldstetten. Here in the Swabian Alps southeast of Stuttgart, the deserted roads would be the epitome of peace and quiet if not for the distant shriek of flat-sixes being wrung out. The 3.8 is not exactly a tractor engine, but the 4.0 is a notable improvement. Its wonderfully linear power curve peaks at 8250 rpm, while torque does so at 5750. "A racing engine like this needs to explode at the top," says Andreas Preuninger, project leader for special vehicles at Porsche. Explode it does, but, despite its 8500-rpm redline, the 4.0 accelerates smoothly and without any hiccups from just above idle. There is so much punch across the rev band that it's not uncommon to be in a gear higher than with the 3.8. The figures speak for themselves: Porsche claims 0–60 in 3.8 seconds, 0–120 in less than 12, and a redline-limited top speed of 193 mph. Of course, the company claimed the regular GT3 would do 60 in 4.0 seconds, and we recorded 3.6 for that car. Figure on the 4.0 managing the deed in around 3.4 seconds, with the quarter-mile taking about 11.6.



Porsche Perfected. And Pricey
The RS 4.0’s handling is virtually perfect, and the transition to oversteer is smooth and easy to manage. The power steering is perfectly weighted and linear; the brakes bite immediately and hard. Carbon-ceramic discs are optional, but even the base setup is among the best on the market. Porsche’s dynamic engine mounts are standard, and while they add four pounds or so, the way they firm up to better manage the rear-mounted engine’s mass during hard cornering easily offsets that demerit.

Both the suspension and rear spoiler can be adjusted for track use. Up front, dive planes mounted at the corners of the fascia do an admirable job of countering the high-speed lift that still afflicts some 911s.

Expectedly, the RS 4.0 is lighter than a GT3 RS. The hood, front fenders, and seats are carbon fiber, and, while air conditioning and a radio are standard, buyers can opt out of either or both in favor of lightness. An optional lithium-ion battery saves 24 pounds. Since lithium-ion batteries suffer diminished cranking ability in sub-freezing temperatures, buyers ordering the light battery also get a lead-acid unit for those winter road trips. Inside the RS 4.0 it has one-piece seats (only 18 pounds apiece!), polycarbonate quarter windows and back glass, and roll cage.

All 600 units have already been sold, and you will be able to distinguish them from lesser GT3s by their unique aerodynamic aids and specific striping. The 911 GT3 RS 4.0, likely the coolest road-going 997 ever, is available in only two shades: black or white. Carrara white is special-projects guru Preuninger's favorite. "It is innocent," he says, barely able to conceal his grin.

If there’s one thing die-hard Volkswagen fans visiting this week’s annual Wörthersee Tour in Austria aren’t going to complain about, is the lack of Golf concepts. We have already shown you the Golf GTI Cabriolet and Golf R Cabriolet and now we bring you two more studies based on the flagship Golf R hatchback. The two Golf R Color concepts were first shown at the Geneva Salon this past March and were created to demonstrate the numerous customization possibilities.
The first example sports a mid-tone “Velvet Grey Metallic” exterior finish with polished 19-inch “Talladega” alloy wheels, orange painted brake callipers and carbon mirror caps.

The interior is distinguished by a set of two-tone motorsport seats with the shell finished in a black piano paint, and carbon fiber accents on the steering wheel, gear shift lever and the door sill plates.

The second Golf R Color Concept is painted in “Aplomb Blue” and comes equipped with 19-inch “Glendale” wheels that are new to the Golf line-up, while the exterior mirror caps, interior accents and the door sill plates are made of carbon. It also gets motorsports seats with the difference being in the color options.

After a long few months of back and forth rumors and prototypes, the leadership of the Volkswagen group have finally given the go-ahead to the final production of the three mid-engined roadster. All three are said to be available in 2013-2014. They will all use the same (MQB "Modular Querbaukasten") platform mid-engine and rear wheel drive, but will each use different styling for obvious reasons.

Volkswagen will have a style inspired by Bluesport, Audi will be more along the lines of the R4 or e-tron Spyder concepts, and Porsche will shoot for a baby Boxster or 550 Spyder look. Each will then use exclusive interior, with materials more or less refined to reflect the purchase price.

Volkswagen will target the Mazda MX-5 market offering around 23,000€. Audi will try to occupy the same niche market as the BMW Z3 pricing theirs close to 28,500€. While Porsche will place theirs below the Boxster, for about 36,700€.

The engine range will comprise the 1.4 TSI 170 hp, the 2.0 TFSI and updated with power ratings from 235-285 hp and five-cylinder 2.5 TFSI which is rumored to be more powerful than today's version, which has 350 hp. Also, there are talks of the 2.0 TDI Twin Turbo.

Until we see what the styling will be from all three brands, it's great news to know they are confimred and on the way.

Volkswagen has just debuted this Golf GTI Cabriolet concept. No word on the details, but if it follows direction from the hatchback GTI it should have the same 2.0TSI with 210 hp. Both manual and DSG 6-speed DSG transmission are expected.
