In Part One we looked at Clessie Cummins’ development of the first practical and reliable diesel truck engines and his earliest attempts to race diesels in the Indy 500. Though he had succeeded in developing the technology, he still hadn’t achieved the ultimate proof of concept that market success brings. (Read More…)

(Note to readers: This was the piece on Clessie Cummins that should have appeared first. Unfortunately, Part 2 of the series ran first and will be rerun later this afternoon — Aaron.)

clessie-cumminsDiesel engines have been in the news lately, and not for good things. The admission by Volkswagen that it has been using a software device to cheat on government emissions testing of at least some of its diesels may taint compression ignition, oil-fired engines in the passenger car market. The trucking industry, however, will continue to use diesels. That’s mostly because of a guy named Clessie Lyle Cummins.

If you’re an automobile or truck enthusiast you likely know his last name, but just as likely know nothing about him.

His accomplishments date to building a working steam engine for his family’s Indiana farm as an 11 year old in 1899, casting the engine parts from molten iron poured into hand-carved molds. As a teenager, he started to take odd jobs including fixing machinery, which led to a job at the maker of Marmon automobiles — Nordyke and Marmon. He was also member of the pit crew of Ray Harroun’s Marmon Wasp that was the winner of the very first Indianapolis 500 race in 1911, and offered suggestions that made the car faster. Cummin’s loved the Indy 500 and his engines would eventually run there, with some measure of success. (Read More…)

Dieseltec Ram Diesel Burnout

What does a diesel shop in Michigan have in common with a Washingtonian florist and a Hoosier pizza hut? An owner who refuses to serve openly gay customers.

Nissan Titan Cummins Holset M2 Two-Stage System with Rotary Turbine Control

When the next-gen Nissan Titan rolls up to the stage at next year’s Detroit Auto Show, the full-size truck will have a big oil-burner with enough sequential firepower to put all on Truck Mountain on notice.

Fred Diaz with Cummins Diesel For Nissan Titan

Nissan North America sales boss Fred Diaz expects his employer will gain more mind and market share in 2014 in the run-up to the 2016 Titan’s debut in showrooms, a truck promised to be more competitive than the current model.

WardsAuto reports that the next generation 2016 Toyota Tundra pickup will receive the Cummins 5.0L V8 turbodiesel for 2016, the same engine that will be powering the next Nissan Titan pickup, due for 2015. While Toyota had been working on a diesel engine with Hino, Toyota’s heavy-truck division, the economic crash of 2008 shelved the plans. With new found interest in light diesels and the new Ram EcoDiesel leading the way with favorable reviews and excellent fuel economy, Toyota looks to jump quickly into the light diesel truck market.

2014 RAM 1500 Eco Diesel Exterior-005

There’s just something about a diesel pickup truck that makes grown men regress into Tonka-loving children. Even my Prius-driving environmentalist friends in Berkeley admit they secretly want a diesel pickup. The problem of course is that diesel pickups are expensive (the cheapest diesel Ram 2500 is $36,975 and it doesn’t have an automatic transmission, the cheapest oil-burning F-250 is $38,250) and, for the majority of us, the high payload and towing capacities are overkill. While economical in a specific sense, the large diesel trucks aren’t “fuel-efficient” either. Until now. Mark your calendars folks, The 2014 Ram 1500 Eco Diesel is the half-ton truck in America sporting a small diesel engine.

Nothing is more American than the pickup truck. If the stars and stripes thing ever gets old, they will probably get replaced by a RAM / GM / Ford montage.  The other thing that’s quintessentially American is an arms race. No, I’m not talking military hardware, I’m talking about the eternal RAM vs Chevy/GMC vs Ford tuck wars. Who has the best frame? Who has the best engine? Who can haul the most? Be prepared to draw your weapons and click past the jump. Chrysler sent me a 2013 RAM 3500 for a week and then invited me to taste test the refreshed 2014 model for a day.

Sources tell us that Nissan and Cummins will make a joint announcement Tuesday regarding a diesel engine for the next-generation Titan. Our sources suggest the powertrain could be either a Chinese-made 4-cylinder engine or alternately a 5.0L V8. Currently, Ram is the only truck maker to offer a Cummins powertrain. Nissan recently hired Fred Diaz, Ram’s former CEO, to head up Nissan Division’s day-to-day operations.

Christmas is over so we go back to war. This is the newest kill-machine of the Chinese army. It is a 4×4 armored vehicle based on the Dongfeng EQ2050 (thank you America!). The new car seems designed as a hit-and-run fast attack vehicle with a big turret on the roof for a big fat machine gun or rocket-propelled grenade launcher. (Read More…)
