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.

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 Malaysian Grand Prix recap: Surprises and missed opportunities

Mercedes-AMG Petronas pilot Lewis Hamilton drove so well in the run-up to the Malaysian Grand Prix that he said before the race, "Honestly, I don't feel anything is going to stop us." On Sunday, the Sepang race showed what it thought of plans and predictions. Heading into the right-hand Turn 1, Sebastian Vettel practically recreated the dust-up at the Belgian Grand Prix three races ago. When Mercedes' Nico Rosberg swept across from the outside line toward the apex, Red Bull's Max Verstappen had to jink right to avoid, touching Vettel's Ferrari on the inside. Vettel speared straight on and hit Rosberg. Vettel's left front suspension broke, ending his race. Rosberg spun and got moving again, but at the back of the pack. That appeared to put Hamilton on a clear run to the checkered flag. His car looked perfect, his pace was perfect, he easily kept Red Bull's Daniel Ricciardo and Verstappen behind. A result that would have seen Hamilton retake control of the Driver's Championship – at Petronas' home race – got crushed on Lap 41 when Hamilton's engine blew down the main straight. That put Ricciardo in the lead, followed closely by his teammate. Just two laps before Hamilton's exit, Ricciardo and Verstappen had battled for second place with some of the best driving we've seen all season. Ricciardo drove as if exorcising the demons of missed opportunities earlier in the year, keeping the young Dutchman behind. The two Red Bulls took the flag fifteen laps later in that order, clocking the first one-two finish for a team other than Mercedes since 2014. It's Red Bull's first one-two since Brazil 2013, when Vettel and Mark Weber took the top steps at the last race of the V8 era. Rosberg recovered to take third in spite of a ten-second penalty for an optimistic pass on Ferrari's Kimi Raikkonen. The Finn crossed the line 12 seconds later, followed by Valtteri Bottas in the Williams and Sergio Perez in the Force India. In another Belgium repeat, Fernando Alonso drove from the back of the grid to finish seventh. Nico Hulkenberg secured eighth, Jenson Button ninth for McLaren in his 300th grand prix, and rookie Jolyon Palmer scored his first point of the season for Renault in tenth. The issue to trump all others from now until next week's Japanese Grand Prix: Lewis Hamilton's terrible luck with engines. Power unit gremlins earlier this season helped drop the Brit to 43 points behind Rosberg after the Russian Grand Prix.
