CNG-powered Chevy Sonic, Cruze headed your way

The value proposition for a Crazy Diamond Performance CNG ride was a little bit better before gas prices took a dive in the past month. Still, the Michigan-based company, which converts some of Chevrolet's compact vehicles to run on compressed natural gas, received approval late last month from the US Environmental Protection Agency (EPA) for two of its conversion models. And CNG is still pretty cheap. Crazy Diamond will start selling CNG versions of both the Chevrolet Cruze and Chevrolet Sonic. The startup will target fleet operators looking to cut both refueling costs and their carbon footprint. CNG can be found in much of the country in the low $2 range, while the average CO2 emissions are about 25 percent less than those of similar gas-powered vehicles. Average gas prices have tumbled by more than 30 cents a gallon in the last month, according to AAA, but they're still at close to $3. The two models will be able to go almost 300 miles on a full tank of CNG. Crazy Diamond said this summer that it would start selling converted a CNG-powered Cruze that delivers 130 horsepower for as low as $26,000. The turbocharged version goes for about $28,000. Take a look at Crazy Diamond Performance's celebratory press release below. Crazy Diamond Performance recieves EPA approval on its CNG Cruze and Sonic CDP receives EPA approval for its Mono-Fuel CNG Cruze and Sonic. Shelby Township, Michigan, October 30, 2014– Crazy Diamond Performance (CDP) receives EPA approval on its Mono-Fuel Compressed Natural Gas (CNG) Chevrolet Cruze and Chevrolet Sonic. Crazy Diamond Performance has received EPA approval on two new mono-fuel small passenger vehicles, the CNG Chevrolet Cruze and CNG Chevrolet Sonic. These new mono-fuel CNG platforms are the first of a series of small and fuel efficient vehicles coming from CDP, where cost, low emissions and reduced fuel consumption is important for not only fleet owners, but to the general public as well. "Soon to be available, are the 1.8L and 1.4L Cruze and Sonic CNG retrofit systems. These two vehicles represent a change in the status quo, with an OEM level integration of the fuel system and its components" states Michelle Fern, Executive Vice President CDP Inc. These vehicles provide flexibility for fleets looking to purchase a domestic small mono-fuel passenger sedan, but have not had an option until now. There are significant emissions benefits over its gasoline counterpart, with an average reduction in Carbon Dioxide (CO2) of 25%.

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!"

2022 GMC Sierra Denali Ultimate vs. 2022 Ram 1500 Limited Longhorn vs. Ford F-150 Limited | Luxury truck interior face-off

GMC's new uber-expensive 2022 Sierra Denali Ultimate is the latest luxury truck to nudge toward six-figure territory. With demand for upmarket half-tons surging, GMC's otherwise-solid pickup found itself in desperate need of an interior remodel. For 2022, we're getting just that, and it appears ready to take the fight to the segment's best, including the 2022 Ram 1500 Limited and 2022 Ford F-150 Limited. Here's the new Denali Ultimate interior in all of its full-grain, open-pore glory. 2022 GMC Sierra 1500 Denali Ultimate vs. 2021 GMC Denali  Not only did the material quality and styling both improve greatly, but the new truck also gets a completely different shifter setup (truck buyers don't like column shifters anymore, apparently). It would actually be difficult to overstate the quality of the upgrade here; the photos really speak for themselves. It's also worth noting that in addition to looking significantly more upscale than the model it's succeeding, the new Denali interior also differs a bit more from its Chevy counterpart than its predecessor did. Here's the new Silverado High Country for reference: While some elements do carry over, the entire dash design is different, down to the positioning of the heating and cooling vents. While the main HVAC controls are essentially carried over, note that they're pretty much the only ones. Even the horizontal bar of switches running along the center stack is positioned differently between the two. Yep. This is a pretty big upgrade over the 2021 cabin, and clearly the range-topper in GM's truck hierarchy. But what of the competition? 2022 GMC Sierra 1500 Denali Ultimate vs. 2022 Ram Limited Longhorn Southfork This one's tough. We're going to have to spend time in them back to back, but the Ram Limited, with its various anniversary editions and other special permutations, is certainly the interior to beat. To our eyes, the Sierra's more horizontal layout is a bit more modern and perhaps luxurious-looking than the more upright cabin treatment of the Ram, but it's tough to say for certain from photos. Both the Denali Ultimate and Ram Limited carry their upscale feel into their back benches too, which is something we can't say quite as confidently about our next contestant.  2022 GMC Sierra 1500 Denali Ultimate vs. 2021 Ford F-150 Limited The Ford F-150 Limited holds its own, but it's probably the least photogenic of the models we've looked at here, at least apart from the outgoing Denali.
