Future Generations Cars

While America's abject Panamera archetypal continues to be the 300-horsepower V-6, European buyers now accept a best in the anatomy of the 2012 Porsche Panamera diesel. Powered by a 250-hp agent V-6 akin to an eight-speed automatic, it costs absolutely the aforementioned as the gas V-6 and seven-speed twin-clutch PDK. Yet in official Euro tests, it uses alone two-thirds the ammunition with almost the aforementioned performance.
No abruptness again that Porsche expects the agent to boss sub-V-8 Panamera sales in Europe. The V-6 gas engine and even the awfully added big-ticket but almost added economical amalgam will acceptable lag far abaft in the archetypal mix.













So Porsche believes the agent will be a big seller, but the engines's ability isn't up to par with the aggressive set's offerings such as the Jaguar XJ, the Mercedes CLS-Class, and VW Group stablemate Audi A7.
We asked the Panamera's artefact arch why his car trails on ability -- it is, afterwards all, a Porsche. His reply: "We don't wish the agent to be the achievement derivative, but the ability derivative." He went on to accept that because a agent wasn't planned at the alpha of the Panamera program, there isn't amplitude to amalgamation Audi's new 313-hp accompanying turbo adaptation of the aforementioned engine.

To accomplish abiding the agent copy sounds added like a affluence GT than the acreage tractor Porsche congenital in its abroad past, there's some added soundproofing about the monocoque and the engine bay. Unfortunately, that adds some weight. The engine's adamant block and the transmission's torque advocate aswell add pounds compared with the aluminum-block V-6 and PDK gasoline version.
Apart from the badges, you can't acquaint the gas and agent cars afar from outside. Inside, the betrayal is appropriately subtle: the redline position on the tach. The agent is accessible with abundant of the affluence and sports accessories options as the blow of the Panamera lineup. Even the carbon-ceramic brakes are available.





Porsche says the Panamera agent goes from blow to 62 mph in 6.8 seconds. The agnate affirmation for the gas V-6 is 6.3, but the engineers say the aberration is accounted for about absolutely by the slower step-off of the torque-converter agent compared with the PDK-equipped gas car. One advantage to the diesel: The torque advocate manual does a bigger job of abatement calmly through near-stationary burghal cartage than the PDK's clutch.

Once underway, the agent provides added than advantageous performance, and the 405 lb-ft of torque is an unbending, connected bandage from 1750 rpm to 2750 rpm. There's a animadversion babble from algid idle, but all-embracing clarification is added than acceptable. A agent six in the boilerplate of its rev bandage sounds bigger than a lot of gasoline fours.
But that doesn't beggarly the engine is any abundant amusement to use. The burke acknowledgment is consistently hardly soft. There's no abscess of ability or admonition articulation as it spins against redline. No accolade to be had from anxiously timing your activation of the gearshift paddles, because the appearance of the torque ambit agency their timing doesn't amount all that much.

That said, it's bigger than the amalgam Panamera, area the alliance of the gas and electric motors and the aperture and closing of the clamp amid them causes all sorts of adverse inconsistencies and delays in gas pedal response.
But if the agent powertrain is alone able rather than in fact enjoyable, there's affluence larboard to adore about this car. We collection two examples, one on a coil-sprung abeyance with adaptive dampers and 18-inch wheels, and addition on air springs with adaptive dampers and 19s.

The coil-equipped car acquainted acutely natural. Porsche does a agitating job of analogous inputs to outputs on the council and brakes. We consistently acquainted we knew what the car was up to, and on twisty, bouncing German country roads, it generated a attractive activity of confidence. It was well-damped and low on roll. It was simple to get into a nice abounding rhythm, even admitting the Panamera never acquainted like annihilation added than a big, abundant sedan. It wasn't active or sharp, but it was quick and rewarding. And the ride abundance was apparently bigger than your boilerplate German action sedan, aided by the continued wheelbase and low-slung basement position.


The air-sprung car is able anneal itself bigger for aciculate corners in its action mode, but the aftereffect feel jiggly and wooden. Like opting for bowl brakes, traveling for this anatomy and annoy admixture amounts to too abundant anatomy for the engine power.
Accelerating harder everywhere, generally to 80-mph-plus on these arced routes, and again hooning down an autobahn gave us about 23 mpg accumulated in estimated U.S. measurements. Porsche will anon accomplish a 26.4-gallon catchbasin accessible for this car. That would acquiesce for 550 afar of maximum-attack fun amid ammunition stops. Efficiency has its rewards.
