Why Obama Won't Take Your Porsche Away – Takes One, Two, Three And Four

why obama won t take your porsche away takes one two three and four

Take One: The Ruf 911 Greenster EV. From AB Green’s report:

Last fall, Porsche high performance tuning specialist Ruf announced that it had built a prototype electric sports car called the eRuf which was essentially a lithium ion battery-powered 911. That was just the beginning of the story as the company has brought the Greenster here to Geneva. The Greenster is a targa top 911 in the old style with a chopped speedster type windshield. In the back sits a 270 kW Siemens electric motor with 695 lb-ft of torque. The battery pack system has been improved and is now 30 percent smaller in volume, restoring the front trunk space that was lost on the original. The battery pack now has greater power capacity allowing it to release and absorb power faster, enabling more regenerative braking capacity. The battery can apparently be charged in only one hour from a 400V outlet. The next iteration will switch to a twin motor setup and the company is planning a small series production run in 2010.

Porsche 911 have been a favorite target for EV conversions fir decades. Ruf’s version is almost series ready. It will probably have an EPA mpge rating similar to the Tesla’s 256 mpge. How many would Porsche have to sell to increase its fleet average to the amount necessary?

Take 2: The Audi e-tron

Audi plans to build at least 100 e-trons in 2012. After that, expanded series production will commence. This verifies that Audi, and by association Porsche, has the technical and production capabilities to build sufficient e-tron technology 911s by 2016 to average out Porsche’s fleet CAFE.

Take 3: The Mercedes SLS AMG EV

Mercedes has confirmed production of the SLS AMG electric. Zero to 100 km/h in around 4 seconds – putting it on the same high level as the SLS AMG with a 6.3-litre V8 engine developing 420 kW/571 hp. The Germans have embraced electric vehicle technology, and are using their high performance cars as their first production versions. Think Porsche will be the only one without one?

Take 4: BMW Vision EfficientDynamics Concept

Melding the performance of an M3 with exceptionally low fuel consumption, BMW claims a 0-62 mph time of 4.8 seconds while scoring 62.6 mpg (U.S.) on the EU combined test cycle. The power and performance are made possible by combining a fuel-efficient 3-cylinder turbodiesel with one electric motor on each axle. The intelligent combination of these units, together with precisely controlled energy management, simultaneously enhances the dynamic performance and the efficiency of the car. Overall system output is 356 horsepower, and peak torque is 590 lb-ft. The special arrangement of the two motors and diesel engine allows all-wheel drive when driving in all-electric mode. The result is minimum power loss and a harmonious transmission of the power available under all conditions.

Summary: All the major German premium brands are developing advanced electric and plug-in hybrids, and specifically are targeting their top line performance vehicles as the launching pad for production versions. It’s hard to imagine Porsche being left behind. Through weight reduction, engine downsizing and a standard mild hybrid system, current EPA numbers could readily be raise some 30% or more. The balance can be achieved through averaging out its fleet mix with EVs or plug-in hybrids.

The bad news is that early experimenters like Tesla and Aptera will probably get pushed aside and the good news, because of CAFE rules, is that we will see very exciting cars from companies (Porsche, MB, Nissan) that have a lot of money to spend on research and engineering. The unintended consequences are funny. Because of our U.S. Cafe rules we could be forcing car manufacturers to build cars that will be ideal in Denmark, Israel, Hong Kong, Singapore, etc.

Finally, an article on Porsche / Obama that makes an effort, that does not just rehash Porsche PR. Thank you.

Kwik_Shift_Pro4X Thankfully I don't have to deal with GDI issues in my Frontier. These cleaners should do well for me if I win.
Theflyersfan Serious answer time...Honda used to stand for excellence in auto engineering. Their first main claim to fame was the CVCC (we don't need a catalytic converter!) engine and it sent from there. Their suspensions, their VTEC engines, slick manual transmissions, even a stowing minivan seat, all theirs. But I think they've been coasting a bit lately. Yes, the Civic Type-R has a powerful small engine, but the Honda of old would have found a way to get more revs out of it and make it feel like an i-VTEC engine of old instead of any old turbo engine that can be found in a multitude of performance small cars. Their 1.5L turbo-4...well...have they ever figured out the oil dilution problems? Very un-Honda-like. Paint issues that still linger. Cheaper feeling interior trim. All things that fly in the face of what Honda once was. The only thing that they seem to have kept have been the sales staff that treat you with utter contempt for daring to walk into their inner sanctum and wanting a deal on something that isn't a bare-bones CR-V. So Honda, beat the rest of your Japanese and Korean rivals, and plug-in hybridize everything. If you want a relatively (in an engineering way) easy way to get ahead of the curve, raise the CAFE score, and have a major point to advertise, and be able to sell to those who can't plug in easily, sell them on something that will get, for example, 35% better mileage, plug in when you get a chance, and drives like a Honda. Bring back some of the engineering skills that Honda once stood for. And then start introducing a portfolio of EVs once people are more comfortable with the idea of plugging in. People seeing that they can easily use an EV for their daily errands with the gas engine never starting will eventually sell them on a future EV because that range anxiety will be lessened. The all EV leap is still a bridge too far, especially as recent sales numbers have shown. Baby steps. That's how you win people over.
Theflyersfan If this saves (or delays) an expensive carbon brushing off of the valves down the road, I'll take a case. I understand that can be a very expensive bit of scheduled maintenance.
Zipper69 A Mini should have 2 doors and 4 cylinders and tires the size of dinner plates.All else is puffery.
Theflyersfan Just in time for the weekend!!! Usual suspects A: All EVs are evil golf carts, spewing nothing but virtue signaling about saving the earth, all the while hacking the limbs off of small kids in Africa, money losing pits of despair that no buyer would ever need and anyone that buys one is a raging moron with no brains and the automakers who make them want to go bankrupt.(Source: all of the comments on every EV article here posted over the years)Usual suspects B: All EVs are powered by unicorns and lollypops with no pollution, drive like dreams, all drivers don't mind stopping for hours on end, eating trays of fast food at every rest stop waiting for charges, save the world by using no gas and batteries are friendly to everyone, bugs included. Everyone should torch their ICE cars now and buy a Tesla or Bolt post haste.(Source: all of the comments on every EV article here posted over the years)Or those in the middle: Maybe one of these days, when the charging infrastructure is better, or there are more options that don't cost as much, one will be considered as part of a rational decision based on driving needs, purchasing costs environmental impact, total cost of ownership, and ease of charging.(Source: many on this site who don't jump on TTAC the split second an EV article appears and lives to trash everyone who is a fan of EVs.)
