RE: Porsche rolls out 680hp wagon
Discussion
My wife thinks these beheamoths are absolutely gorgeous. I'm not sure about the benefit of the E-stuff, brilliant for your tax code, but when you're out and about actually driving?
Anyway, would it look too much in Paint to Sample - Voodoo Blue? Most of these big cars will surely all be ordered in shades of grey or basalt black.

I can apply about 1000 lb-ft of torque to my wheels with a 6ft breaker bar. I can apply it at about 1rpm. No amount of gearing to this force will make my car accelerate off my drive at a high rate.
What I need is the highest product of the force and the rate. I wonder what we could call this concept?

That's certainly a lot of grunt....although an estate car without additional luggage space because of the batteries seems a bit daft?
Also.....torque-to-weight ratio? WTF? That's an utterly meaningless measurement, one car may have a much higher torque-to-weight ratio than another car, but have lower power-to-weight.....it won't be faster, it would be slower....
Trying climbing hills with a poor torque-to-weight ratio, then you will realise how meaningful it is.Also.....torque-to-weight ratio? WTF?

Queue the pages and pages of arguing over what a shooting brake is 
That's easy, the answer is "a marketing term". 
when it really is shooting, this is still the best "shooting brake" you can buy
I'll get me coat....

I like the back of it, the way it's slanted, kind of like the Honda Accord estate. Kind of looks like a stretched hatchback, while I don't think it's a looker, I think it will have a lot of road presence and will turn a lot of heads, give me a dark grey one that's been driving on a snow gritted m25 for 10 hours, will look like an apocalypse car, I like it!!
By the way I'm on about the Porsche not the Honda

I am so glad others have picked up on the torque-to-weight thing. It's utter nonsense. You can double the torque of an engine by fitting a simple mechanical device...
Indeed. Which is why power to weight is a much better indicator of performance. Something may produce 1000lb ft of torque and weigh 1000kgs but if the engine only revs to 1000rpm, then it won't be as quick accelerating as something which weighs 1000kgs, produces 250lb ft of torque at 8000rpm, for example; despite having 1/4 of the torque to weight.
