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!"

GM CEO Mary Barra predicts mass electrification will take decades

General Motors is allocating a substantial amount of money to the development of electric technology, but Mary Barra, the firm's CEO, conceded that battery-powered cars won't fully replace their gasoline-burning counterparts for several decades. She stressed the shift is ongoing, but she hinted it will be slower than many assume. "We believe the transition will happen over time," affirmed Barra on "Leadership Live with David Rubenstein," a talk show aired by Bloomberg Television. She added that not every car will be electric in 2040. "It will happen in a little bit longer period, but it will happen," she told the host. She was presumably talking about the United States market; the situation is markedly different in Europe and in China, where strict government regulations (and even stricter ones on the horizon) are accelerating the shift towards electric cars. On the surface, it doesn't look like General Motors has much invested in electrification; the only battery-powered model it sells in America in 2020 is the Chevrolet Bolt (pictured), which undeniably remains a niche vehicle. Sales totaled 16,418 units in 2019, meaning the Corvette beat it by about 1,500 sales. In comparison, Cadillac sold 35,424 examples of the aging last-generation Escalade during the same time period. And yet, the company isn't giving up. It has numerous electric models in the pipeline including a slightly larger version of the aforementioned Bolt, the much-hyped GMC Hummer pickup, and an electric crossover assigned to the Cadillac brand. These models (and others) will use the Ultium battery technology that General Motors is currently developing. Its engineers are also working on a modular platform capable of underpinning a wide variety of cars. Bringing these innovations to the market is a Herculean task. EVs may not take over for decades, but Barra and her team must believe their 2% market share will increase significantly in the coming years if they're approving these programs. Autonomous technology is even costlier, more complicated, and more time-consuming to develop. Barra nonetheless expects to see the first General Motors-built driverless vehicles on the road by 2025. "I definitely think it will happen within the next five years. Our Cruise team is continuing to develop technology so it's safer than a human driver. I think you'll see it clearly within five years," she said on the same talk show. Her statement is vague but realistic.

2018 Hyundai Accent vs subcompact sedans: How it compares on paper

Hyundai first revealed the new 2018 Hyundai Accent a few months ago, but that debut was in Canada for the Canadian-market car. We didn't get our look at the U.S. version until just recently, which is when we also finally got plenty of specifications on the little car. So as we did with the Genesis G70, we've brought you a breakdown of the Accent's specs and some of the segment's best and most popular: the Nissan Versa, Kia Rio, Chevrolet Sonic and Toyota Yaris iA. Before we get to the chart, let's give you a quick reintroduction to the 2018 Accent. The subcompact is completely new this year, and under the hood is again a naturally aspirated 1.6-liter four-cylinder engine. It makes 7 fewer horsepower and 4 fewer pound-feet of torque than the outgoing model with totals of 130 horsepower and 119 pound-feet. This drop in power probably won't be noticeable, though. It's also available with either a manual or automatic transmission, both featuring six speeds. Fuel economy hasn't been announced, but the Rio's numbers below are probably a good indicator as they share powertrains. The one thing that isn't available with an Accent is a hatchback. According to Autoweek, the hatchback was canned with the assumption that hatch buyers would simply purchase an example of the upcoming Kona crossover. But if you want a traditional subcompact hatch from South Korea, Kia is happy to oblige, as the Rio is still available as a hatchback. Learning that the Kona may have killed the Accent hatch causes us to wonder if Kia brought the Rio hatch to the U.S. because it wasn't planning on offering the Stonic.
