The Tesla Model S Controversy: Understanding the Effects of Temperature on Electric Vehicle Efficiency and Range

Posted: 18 Feb 2013 12:22 PM PST

Thus far, plenty of ink has been spilled regarding the Tesla Model S and the fallout from the New York Times article, and it even showed up in our latest podcast. I feel like my perspective on this topic, as someone who has worked in the EV space as an engineer for the last four years, as well as driving a family owned Nissan Leaf for the last year and a half, is a bit different from our editors who discussed it, as well as most of the others who have written about it.

I’m not particularly interested in getting involved with the back and forth or analyzing what either party said - I feel like the Times reporter didn’t really understand how EVs work, nor how to drive them, and I don’t really agree with Elon Musk’s Matlab data infused response (it felt too vitriolic to get across any point other than Tesla being angry about the article). And just to go back to the point about not understanding how EVs should be driven, you have to tailor your driving style to suit the powertrain in order to get the maximum out of the EV - if you don’t want to, you’re going to be disappointed. Consider it like needing to switch keyboard shortcuts when you move from Windows to OS X - it’s a slight mental recalibration that has to happen for you to use the platform to its fullest. But that’s another story for another time. 

What I feel like is getting lost here is actual EV performance in cold weather, or hot weather, or really anything in the way of hard numbers. We all know that battery performance is reduced in more extreme environmental conditions, and that all cars, regardless of powertrain type, consume more energy (fuel or battery) in those extreme climates. Unfortunately, quantifying these general ideas is a bit more difficult. That’s where I come in. 

NVIDIA GeForce 314.07 WHQL Available

Posted: 18 Feb 2013 09:37 AM PST

NVIDIA's beta R313 driver with performance enhancements for Crysis 3 (among other titles) has now received WHQL certification. We wouldn't expect much of a difference in performance relative to the beta drivers, but NVIDIA states they provide up to a 5% performance improvement in Crysis 3 with GTX 680. As usual, you can grab the drivers for all current desktop and mobile NVIDIA GPUs:

Desktop 314.07 Windows Vista/7/8 64-bit
Desktop 314.07 Windows Vista/7/8 32-bit
Mobile 314.07 Windows Vista/7/8 64-bit
Mobile 314.07 Windows Vista/7/8 32-bit

Thanks go as usual to reader SH SOTN for the quick notification.
