2014 Porsche Panamera Diesel is something to torque about

Porsche has been in the business of slaying sacred cows for the better part of a decade, from venturing into the SUV space with the Cayenne to the four-door realm with its Panamera hatchback. And if those vehicles didn't leave brand purists apoplectic enough, Porsche has been adding diesel and hybrid power to its portfolio, thought to this point, neither alt-fuel motivator has made its way into the brand's sports car lineup.
Today's Frankfurt Motor Show effectively marks the second-generation of diesel power in the Panamera, and this updated 3.0-liter V6 features 300 horsepower (50 ponies more than last year) and a whopping 479 pound-feet of torque, available from 2,500 rpm. That power is achieved with a new higher-pressure, water-cooled turbo and redesigned engine internals that include a new crankshaft and pistons. The newfound increase is said to raise top speed to 161 miles per hour from 152, and drop the car's 0-62 mph time from 6.8 seconds down to 6.0. It also figures to be a better handler, with a new torque-vectoring rear differential borrowed from its gas-powered brethren and a reworked transmission for crisper shifts. The suspension has also been retuned, along with the updated 2014 visuals first revealed at April's Shanghai Motor Show.
No word yet on the North American sales prospects of this diesel Panamera, but we imagine that depends in part on how well the Cayenne diesel is selling.

Hamann Porsche Macan S Diesel promises more performance, questionable looks

Ignore the Gulf Oil livery for a minute (we know, it's hard). What we have under the blue-and-orange paint scheme is a diesel-powered Porsche Macan S, which is fascinating enough in and of itself. But this particular example has been upgraded by the folks at Hamann, for that added bit of oomph. Power output from the 3.0-liter V6 diesel is up from 258 horsepower to 300 hp. We buy diesels for torque, though, so it's the 494 pound-feet, up from 427 lb-ft, that really gets us excited about this modded Porsche. Taken together, the Hamann Macan S Diesel can hit 60 miles per hour in a decidedly un-diesel-like 5.7 seconds, down from 6.1 seconds. German tuners like Hamann are not known for their subtlety, of course, so beyond the power ugprades, the company has made its own aesthetic tweaks. The new body kit is, um, aggressive? Okay, it's really not very nice to look at. The Macan is a handsome vehicle on its own, but Hamann's efforts haven't done it any favors. It's extremely busy, particularly around the front and rear ends, where the tuning company's efforts seem focused. We're guessing some attention has been paid to the cabin, although it's impossible to tell on the Geneva show car, which has had all of its windows heavily tinted. Here's hoping any changes to Macan's cleanly styled cabin are kept to a minimum. Take a look at our full crop of live photos of the modded Macan, direct from the floors of the Geneva Motor Show. High-performance power, long-distance comfort, extravagance: the benchmark figures of the formidable Porsche Macan S Diesel are impressive. For all fans of the dynamic vehicle Hamann's tuning experts now sets the bar even higher. As is generally known, the model's name "Macan" was derived from the Indonesian word for tiger – and exactly this tiger Hamann frees from the ties of a series actor. The face of the Macan, which Hamann presents in the S Diesel version in Geneva, has self-confident traits. The tiger seems ready to jump – an effect achieved by the low line of the front apron and the lowering of the car. Hamann's aerodynamics attachment emphasises the sharp "teeth" of the Macan Turbo's standard front and sets distinctive accents. The car refiner's interpretation of the Macan S Diesel appears well-toned and is coherently continued in powerfully shaped wing extensions making the predator's body grow by twelve centimetres in width.

'Faster. Farther.' dives into the history of Porsche racing tech

No doubt, Porsche has produced some of the best endurance racecars around, such as the turbocharged, slant-nose 935 of the 1970s and the ground-effects-enhanced 956 and 962 of the 1980s. But the company's most famous racecar, its first overall winner at the 24 Hours of Le Mans, was the 917.
The 917 embodied many of Porsche's technological achievements up to that point, such as the company's first 12- and 16-cylinder engines (the flat-16 was never used in competition), fiberglass bodies that implemented early aerodynamic practices and the use of new, exotic materials, such as magnesium and titanium.
The racecar was commissioned by the head of Porsche Motorsports, Ferdinand Piëch, to win overall at the 24 Hours of Le Mans in 1970, after he realized a loophole in the rules that allowed cars to compete with engines up to five liters in the Sport category if they were also production models. Piëch saw opportunity: the top prototype class was restricted to three liters; the production minimum to compete in Sport was 25 cars. And so, with much effort, Porsche assembled 25 "production" 4.5-liter 917s and had them parked in a neat line for the race inspectors to verify their legitimacy. It didn't take long before people realized the new Porsches were much faster than the prototype racers, with a top speed approaching 250 miles per hour.
