It won't be long now before Nissan Leaf finally overtakes Chevy Volt

The two best-selling plug-in vehicles ever are the Chevy Volt and the Nissan Leaf. When the two vehicles launched in late 2010, the plug-in hybrid Volt quickly outpaced the all-electric Leaf and, despite lots of ups and downs since then, continues to hold on to a cumulative sales lead. This will change in 2015. Cumulatively, from November 2010 through November 2014, the Volt sold 71,867 units while the Leaf trails with 69,220. That's a difference of just 2,647. Based on current trends (with the Leaf selling around 2,500-2,700 a month and the Volt at 1,500-1,700) we expect the Leaf to take over either in January or, more likely, February when the Leaf takes over as the most popular plug-in car in America. Perhaps even March, depending on how low the numbers are for January and February, which are always slow sales months in the US. Of course, once it takes the crown, the Leaf can't expect to easily hold on for long. A new Volt is coming in the second half of 2015, likely beating a new Leaf to market. The question is, then, how well the Chevy sells with all of its new bells and whistles. Do you think the Volt will be the comeback kid once the 2016 model becomes available?

Bob Lutz builds the case for a mid-engined Corvette

Rumors of a mid-engine Corvette are like automotive industry folklore at this point. Every once in a while, news pops up that it might be happening or is under development, but nothing actually ever comes to fruition as something people can actually buy. The latest spy shots strongly suggest a mid-engine 'Vette is in the cards, yet again, possibly for 2018. Now, an op ed by former General Motors executive (and definite performance car fan) Bob Lutz in Road & Track gives the inside scoop on the history of one of these proposals and lays out how to make it happen today. According to Lutz, the company's engineers believed the C6 ZR1 was at the limit for front-engine, rear-wheel drive performance in that package, and the only solution was to move the powerplant behind the driver. Lutz even got then CEO Rick Wagoner on board. The scheme made it at least as far as clay models for mid-engine versions of the 'Vette and Cadillac XLR. Eventually, a lack of money got in the way, though, bringing the project to an end. Lutz puts a lot of faith in GM's current leaders, especially Mary Barra and Mark Reuss. He thinks the chances of a mid-engine 'Vette happening this time are better than 50 percent. The model, rumored to be named Zora, could offer over 700 horsepower in an ultra lightweight body and be priced at about $120,000 to "suck the doors off everybody." Head over to Road & Track to get some insights from this highly respected and entertaining auto industry veteran. Related Video:

Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"
