Why it's difficult to accurately test the efficiency of a plug-in car

When it comes to electric vehicles and plug-ins in general, the Environmental Protection Agency-certified range is a hugely important number. While actual range anxiety is largely psychological, the magic number does provide a point of comparison of buyers considering one EV over another. The driving distance is also often touted by automakers when marketing their models. Unfortunately, as Green Car Reports finds in a recent deep dive, the way the EPA calculates the figure is a convoluted mess, and discovering the reasons why is definitely worth the read. The issue isn't about bad science but instead comes down to vague wording. The EPA's accepted range test is sourced from an evaluation called J-1634 from the Society of Automotive Engineers, and it seems to provide balanced results for vehicles that automatically reach a single state of charge when plugged in. However for models with multiple charge settings, the situation gets complicated very quickly. Of course, these modes are often created in the software, meaning that a car's certified driving distance can change with just a few taps of the keyboard without the real world results owners might experience actually changing. By showing the test's effects on the certified range for the Tesla Model S, Nissan Leaf and Mercedes-Benz B-Class Electric Drive over the last few years, Green Car Reports makes a compelling argument that it's the evaluation that needs to change. Thankfully, it appears that the solution is a very simple one. Get the details here.

Nissan GT-R goes 183 mph on ice in Russia

When a pair of Russian pilots wanted to set a local ice-speed record, they chose a stock Nissan GT-R for the task. Roman Rusinov, a Russian race car driver, and Andrey Leontjev, a Russian auto journalist, took Godzilla to Lake Baikal and ran it up to 294.8 kilometers per hour (182.8 miles per hour) across frozen stuff estimated to be 1.4 meters thick.
While the worldwide record of 205.48 mph was set by Juha Kankkunen in a Bentley Supersports Convertible, the mark achieved by Rusinov and Leontjev establishes a new Russian record. Well done, boys. You can watch it all go down in the video below.

Nissan prices limited-edition 2014 GT-R Track Edition from $115,710*

Nissan has released its pricing for the model-year 2014 GT-R, including the new Track Edition of Godzilla. The 2014 Nissan GT-R Premium will now command an MSRP of $99,590, while the Black Edition will go for $109,300 and the new Track Edition will ask $115,710 (*not including a $1,000 destination and handling charge for all models).
Nissan calls the GT-R Track Edition its most exclusive model, which makes sense as it will be limited to just 150 examples for the US market. The competition-ready Track Edition gets Bilstein DampTronic shocks and revised spring rates; all chosen after more development work by Nissan engineers at the Nürburgring. (Good work, if you can get it.) A carbon fiber rear spoiler and six-spoke black wheels come with the package, as do blue-trimmed, high-grip front seats inside. To save weight, the car's rear seats have been deleted in this model.
