2015 Porsche Panamera S First Drive

Porsche brought the Panamera in for its garage makeover and drove it out looking almost exactly the same. Turns out it was one of those fancy German refreshes where everything happens in places you can't immediately see, as we found recently on the 2015 Volkswagen Jetta TDI. The marquee revision across the lineup is under the hood, where every engine gets, at the very least, more power. Such is the case for the naturally aspirated V6 in the entry models, fitted with an increase of 10 horsepower for a total of 310. The same goes for the naturally-aspirated 4.8-liter V8, which lives only in the Panamera GTS now, and gets 10 more hp for a total of 430. That same V8, twin-turbocharged in the Turbo model, is graced with 20 more ponies for 520 hp. The mightiest marquee revision is saved for the S models, which surrender their use of the 4.8-liter V8 and get a 3.0-liter, all-aluminum, twin-turbocharged V6 in its place. It's a brand-new engine designed in-house and related to the 3.6-liter V6 in the base models, but with new features like a magnesium timing chain cover, variable camshaft timing for the intake and the exhaust valves, and a new fuel- injection system. Putting out 420 hp and 384 pound-feet of torque, it's got 20 more hp and 15 more lb-ft than the V8 it replaces. What's more, torque used to peak from 3,500 to 5,000 rpm, but the new torque curve maintains maximum twist from 1,750 to 5,000 rpm. It is less thirsty as well, posting an estimated fuel economy of 17/27 miles per gallon city/highway, besting the 16/24 city/highway of before. An improved stop-start mechanism contributes to this, as it cuts the engine earlier, and the coasting function benefits from a new disc clutch that can decouple the seven-speed PDK dual-clutch transmission from the driveline. As we wrote in our Panamera S E-Hybrid review, you'd need to be obsessed with the Panamera to notice the sheet metal changes around that engine. It's the perfect car to ask, oh so coyly, "Notice anything different about me?" while you stand there dumbfounded, silently thinking, "No." Here is your cheat sheet: the front and back ends are "tighter," meaning faintly more squared off, the front intakes are larger, the tailgate gets wider rear glass over the same-sized opening, the rear spoiler is wider, and the rear license plate bracket has been mounted lower. But even now that you know what the changes are, odds are still 200-to-1 against you actually noticing.

Mercedes-AMG GT S pit against Porsche 911 Turbo in Evo Deadly Rivals test

When Mercedes-Benz announced that its all-new AMG GT would start at $129,900 deeply undercutting the $200,000-plus of its predecessor, the SLS AMG, immediate questions focused on how it'd stack up against the latest crop of high performers that occupy the mid-$100,000 range. Evo, over in the UK, didn't have to wait all that long. The latest installment in the outlet's "Deadly Rivals" series compares the AMG GT with the latest Porsche 911 Turbo. On paper, the test is sure to be interesting. The Mercedes uses a 4.0-liter, twin-turbocharged V8 with 503 horsepower and 479 pound-feet of torque, while a seven-speed AMG Speedshift dual-clutch shuffles power to the back axle. The 911 Turbo's formula is more of a known quantity – 520 hp from a twin-turbo, 3.8-liter flat six with the company's own PDK working in unison with all-wheel drive, torque vectoring and rear-axle steering. Of course, we're not going to spoil the results for you. Take a look at the video up top, and let us know what you think of Evo's latest track battle.

Porsche 912 is no longer the brand's black sheep

If you haven't looked recently, prices for many vintage Porsche 911s are now well out of the realm for mortal men to purchase. However, the growing values have their advantages because they mean that the 912 is being better accepted as a member of the Porsche family. In a new video, Petrolicious talks to one owner about his mildly modified example while the coupe zips through the backroads and city streets of France. Launched around the time of the 911, the 912 shared its body but retained the four-cylinder engine from the 356, rather than the new six. The older mill helped make the 912 cheaper to buy, but it also tarnished the coupe in the eyes of Porsche fans for years. Much like the four-cylinder 914 and 924, the 912 just seemed like a black sheep in the shadow of its more powerful brother. Following two massive changes to his life, Julien Borne bought a 1967 912 as a project to get back on the road. After hours of welding, wrenching and beating out panels by hand in his grandparents' neglected country house, he crafted this gorgeous example. Check out the video to hear his story, as Petrolicious shows why the model's stigma is wearing off.
