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.

2016 Mercedes-Maybach S600 First Drive

Imagine the audacity: during the salad days of the early 2000s, the company that invented the automobile – already synonymous with class-leading luxury – sought to further expand its portfolio by crashing the ultraluxury party. Going up against the likes of Rolls-Royce and Bentley, Mercedes-Benz traded its unmistakable Three-Pointed Star for a Mighty Mouse-like logo, exhuming a stately, long-dead German marque originally founded in 1909. The long-wheelbase Maybach 62 listed at an epic $360,000, while later spinoffs included curiosities like the nearly $700,000 Zeppelin, and a roofless, seven-figure limousine dubbed Laundaulet. By the time the financial bubble finally burst in 2008, the brand's fate was all but sealed, with US sales dropping into the double digits. It limped along another four years, but when the nameplate finally went kerplunk, it left behind it a trail of disappointed movers, shakers, moguls and rappers. The perfect postmodern metaphor for the brand's funeral pyre? Kanye West and Jay-Z's Otis music video, in which a perfectly fine Maybach is chopped and deconstructed, flames spewing out the tailpipes as it powerslides through an empty parking lot. Meet The (Sorta) New Boss Rising from the ashes of hubris is the 2016 Mercedes-Maybach S600, a recalibrated stab at high-end luxury with a startlingly similar, yet different, approach to its forbear. Like the last go, the new sled features a significantly longer wheelbase, which stretches 8.1 inches over the standard S600. Additional sound damping helps it claim the quietest rear cabin in all of production automobiledom, and posher trim bits include a rim of wood surrounding the reclining rear seats. Among the livery-focused special features is a rearview mirror-mounted microphone to amplify the driver's voice, an available rear fridge, and an executive seat package with folding tray tables. The super high-end hallmarks are there – a twin-turbo V12 dispatching sub-5 second 0 to 60 times, a stunning 24 speaker Burmester sound system, double-M branded silver plate champagne flutes, et al. – but the hyperinflated price tag is not. Starting at $189,350, roughly half the cost of the old flagship, the new Maybach isn't even the most expensive Mercedes-Benz you can buy. That distinction goes to the S65 AMG Coupe, which empties your coffers to the tune of $230,900.

SRT Viper dukes it out with Mercedes SLS Black Series in new Head 2 Head

In Episode 36 of Motor Trend's Head 2 Head, now that the Corvette ZR1 is no more, Jonny Lieberman has to look overseas to the Mercedes-Benz SLS AMG Black Series for a challenger with similar philosophy to the SRT Viper: long hood hiding a high-horsepower engine set way back, rear-wheel drive, tiny trunks. That puts the Viper's 8.4-liter V10 with 640 horsepower and 600 pound-feet of torque against the SLS AMG's 6.2-liter V8 with 622 hp and 468 lb-ft.
However, the congruences in philosophy and magnitude of numbers doesn't translate to the driving experiences of the two, which are literally and figuratively on different continents. Lieberman gets a handle on the two of them on Northern California roads, Randy Probst then finds out how, and how quickly, they can lap Laguna Seca.
They both get kudos for being improvements on their original sources, but only one of them can take the win. You can find out by watching the video below.
