Toyota promoting Mirai as if hydrogen tax credit never went away

At the end of December, the US federal government let the $8,000 tax credit for hydrogen-powered vehicles expire. Despite this little wrinkle, Toyota is still promoting the upcoming 2016 Mirai fuel cell vehicle as a car that will cost under $50,000. In some cases a lot less, since it may also qualify for a $5,000 incentive in California. The car has a $57,500 MSRP, but Nihar Patel, vice president of North American Business Strategy for Toyota Motor Sales, spoke at the 2015 Washington Auto Show last week, and said that the Mirai could cost $44,500 in California. You can see this in the video at around minute four. Toyota knows that the federal incentives have expired, since the real news from the show was Patel's public request to the federal government that the $8,000 tax credit be extended. "We think that the federal credit expiration last year puts [hydrogen] customers in a fairly disadvantageous postion," he said. Plug-in vehicle buyers can still get up to $7,500 tax credit and, "we believe that this inequity needs to be fixed," he said. You can see this in the video at minute 10:20. Toyota said including both the after-incentives price and the call to reinstate those incentives was intentional since it shows a discrepancy between hydrogen and plug-in vehicles in the eyes of the feds. We asked Toyota's director of Energy and Environmental Research, Technical and Regulatory Affairs, Robert Wimmer, for more details on Toyota's request. "[The Mirai] being a ZEV and battery electrics also being ZEVs, we just want to make the playing field as level as possible," he said, adding that any extension would last "for the run of the vehicle," which would be three years. He admitted that the extension might only be for one or two years, if it happens at all. (A Toyota spokesperson clarified to AutoblogGreen that the Mirai program will not end after three years.) And that's the problem. "The tax process is difficult to predict," he said. "The two challenges we have now are that both houses of Congress are Republican and also that there has been talk for a while about comprehensive tax reform. If that moves forward, then extenders would probably be put on the back burner as comprehensive tax reform is discussed." Wimmer would not reveal any details about how Toyota is pressuring the government to act, only saying that Toyota's has people lobbying up on Capitol Hill.

Where the 2023 GMC Sierra AT4X fits into the hierarchy of off-road trucks

The world of off-road pickups sure seems like it's getting crowded, but the reality is that half-ton trucks were always pretty capable, even with what seemed like fairly basic 4x4 packages. It wasn't until recently that manufacturers really started to carve out different off-road niches for their mainstream pickup offerings. With the introduction of the 2022 GMC Sierra 1500 AT4X (alongside its mechanical twin, the Chevy Silverado ZR2), the crowd has grown even thicker. Even we have trouble keeping up with the increased segmentation of off-road pickup trucks, so we threw together this handy guide to help you understand just where these various packages fit into the broader pickup hierarchy. Let's dive in.  Your basics If we say "Z71" or "FX4" to you, both will probably ring a bell. That's because they've been around a few days short of forever and their respective customers have grown so used to these package codes that OEMs got into the habit of just plastering them on the side of so-equipped truck beds. Anybody who sells a pickup truck offers some sort of basic off-road prep package like this one. Z71 is found on GM vehicles; FX4 is Ford's. Ram just calls it "Off Road Group," but no matter what you call them, they're all pretty similar.  Typical upgrades for this category include some additional ground clearance, a basic all-terrain tire, heavy-duty suspension upgrades and likely either a limited-slip or locking rear differential. These are pretty handy for anything beyond a rutted dirt road. On newer trucks — especially on higher trim levels — you'll probably also get some dedicated off-road drive modes.  Mid-range This is where things start to get interesting. To qualify for this category, a locking rear differential is a must. Most of the names in this segment are well-established too, though some (Nissan Titan Pro-4X, anyone?) may not necessarily be on your radar. The Toyota Tundra TRD Pro checks in here, as does the Ram Rebel, Chevy Silverado Trail Boss and GMC Sierra AT4 (no X!).  Realistically, if there's somewhere you need to go and one of these trucks won't do it, you might want to consider a helicopter. But it's 2021, and our thirst for capability is strong, so of course, there's a way to spend more of your money on this type of thing. Onward! Entry-hardcore Here we are, the home of the new 2022 GMC Sierra AT4X and Chevrolet Silverado ZR2. This is a tiny niche, otherwise occupied only by the Ford F-150 Tremor.

The tumultuous history of the diesel engine

Volkswagen, diesel's most enthusiastic patron, deceived everyone about the amount of emissions its cars were putting out. We have covered this latest massive automotive scandal in great detail, and there are surely more fascinating revelations to come. It turns out that this is just the latest episode in the epic story of the controversy and intrigue surrounding the diesel engine, and its inventor. This is the story of the tumultuous birth and interesting evolution of the compression-ignition engine at the center of the VW scandal. Napoleon III Got Rudolf Diesel Deported Rudolf Diesel was born in Paris in 1858. His Bavarian parents had settled in France where his father, Theodor, was a leather goods manufacturer. When the French Parliament declared war on Prussia, kicking off the Franco-Prussian war, the Diesels fled to London. When he was 12, Rudolf went to live with his aunt and uncle in the Bavarian university town of Augsburg. It was his parents' hometown, and importantly, it's where Rudolf began studying at the Royal County Trade School. His time in Augsburg, graduating at the top of his class from trade school that laid the groundwork for all that was to come. Diesel Nearly Blew Himself Up An early career in refrigeration saw Diesel running R&D in Berlin for Linde, a company started by refrigeration pioneer Carl Von Linde, one of Diesel's professors. His ambition to branch out beyond refrigeration, and his deep understanding of thermodynamics, led to efficiency experiments with steam engines. Diesel was trying to create an engine that didn't waste heat from the combustion process, therefore getting the most work out of the fuel. Instead, he was nearly killed when an experimental ammonia vapor steam engine exploded. Recovery took many months, and during some of that time, he was no doubt planning his next experimental engine, based on the theoretical Carnot cycle. His Engine Was An Attempt To Stick It To The Man Steam engines were expensive to run and wasteful. Diesel thought the efficiency of his design would be a way for the small business to compete with the dominant industrial giants. It was, and it did, but big business is equally passionate about chasing efficiency. Diesel engines quickly proliferated in industries both grand and cottage. Rudolf Didn't Really Invent The Diesel As We Know It Instead, he improved an existing one to a significant degree. The Diesel engine could be considered an evolution of the "hot-bulb" engine.
