Rolling coal is one of the more contentious forms of automotive customization, primarily because it’s as much associated with vindictive cruelty as it is with having a good time.

In fact, there are probably more videos on YouTube of modified diesel truck owners blasting cyclists, protesters, activists, and EV drivers with sooty smoke than there are not. Over the last few years, rolling coal has become a way for many to showcase their anti-environmentalist and hard-right viewpoints. However, regardless of your politics, being on the receiving end of a diesel truck intentionally running ultra-rich is obnoxious and several states have attempted to ban the practice.

After three failed attempts, Colorado finally managed to pull it off. While earlier attempts fizzled, mainly due to concerns expressed by the Republican-controlled Senate over how regulations might affect the trucking and agriculture industries, a revised bill better addressed those concerns. Now, law enforcement will undergo training to help differentiate between a smoky work truck and those specifically designed to run rich for the purpose of rolling.  (Read More…)

You want a pickup truck.

You want a small pickup truck.

Unfortunately, such a thing no longer exists, at least not north of the Rio Grande. You’ve migrated your desire to the “midsize” sector, a class in which the Toyota Tacoma, Nissan Frontier, Honda Ridgeline, and two General Motors candidates offer a quintet of possibilities.

Yet a major issue crops up when you begin comparison shopping and discover three full-size issues standing in the way: strong incentives on full-size pickups, full-size truck fuel efficiency comparable to midsize trucks, and full-size capability and interior volume far exceeding that of midsize pickups.

No wonder 85 percent of pickup buyers opt for a full-size truck. Still, 2016 was the best year ever for the Toyota Tacoma and the best year since 2001 for the Nissan Frontier. 2017 is on track to be the Honda Ridgeline’s best year since 2007. The Tacoma has a legendary reputation for toughness. The Frontier is the small-truck traditionalist’s pickup of choice. The Ridgeline is unusual in almost every way.

What unique attribute does GM’s duo manifest? This 2017 GMC Canyon SLE Crew Cab 4×4 has diesel. Diesel fuel in a diesel engine with diesel towing capacity, diesel fuel economy, and a diesel sound owners of decade-old Jetta TDIs will love. (Read More…)

The particles are one-fifth the diameter of a human hair. They lodge deep in the lungs and never come back out. Children and the elderly are particularly affected. They cause lung cancer, lower resistance to disease, and make it difficult to breathe. It’s impossible to accurately estimate the deaths that occur as a result of exposure, but the EPA has suggested that it could be between 500 and 8,000 per million people.

Toxic exhaust from diesel engines, in both the form of gases and particulate matter, is a major contributor to health problems. It is also a leading cause of smog, which has led Paris to ban diesel cars on alternate days during high-smog periods and to plan for a comprehensive ban on diesel passenger vehicles in the city by 2020.

For Europe, this is a case of chickens coming home to roost.
