Honda, GM fuel-cell partnership wants to reduce hydrogen refueling costs

To paraphrase the old political adage, it's the cost, stupid. Dollar signs are what's prompting Honda and General Motors to partner up to accelerate development of a hydrogen fuel cell system. With about half the cost of a fuel-cell system tied up in its fuel-cell stack, GM and Honda are looking to help each other drive costs down, according to a presentation by GM fuel cell research and development director Mark Mathias said in a presentation at the SAE 2014 Hybrid & Electric Vehicle Technologies Symposium. According to Green Car Congress, Honda and GM are looking to reap the fruits of their collective labor by 2020. As with other automakers, the high cost of producing fuel-cell vehicles is the fly in the ointment of a powertrain technology that combines the same range as gas-powered vehicles but with zero emissions. In the meantime, Honda, which makes the very limited production FCX Clarity fuel-cell vehicle, is slated to start selling its own mass-market fuel-cell vehicle in 2015. The two automakers made their partnership announcement last summer and said they contribute to expanding hydrogen fuel infrastructure in California during the next few years. Earlier, Ford, Mercedes-Benz parent Daimler and Nissan also said they would work together to speed up fuel-cell technology development.

Compact SUV Comparison: Specs, pics and reviews of every brand's crossover

Honda CR-V vs Toyota RAV4. Chevy Equinox vs Ford Escape. Mazda CX-5 vs Subaru Forester. Whichever combinations of compact crossover SUV you're considering, there's probably a comparison test or chart out there to read. Heck, you can even create a three-car comparison yourself here at Autoblog. However, if you want a bunch of that information all in one convenient place, well, here it is. Our mega comparison of specs, features and photos of compact SUV entries from every mainstream manufacturer that sells them. That includes the 2018 Chevrolet Equinox, 2018 Ford Escape, 2018 GMC Terrain, 2018 Honda CR-V, 2018 Hyundai Tucson, 2019 Jeep Cherokee (it's already on sale with notable changes from 2018), 2018 Jeep Compass, 2018 Kia Sportage, 2018 Mazda CX-5, 2018 Mitsubishi Eclipse Cross (none of Mitsu's SUVs are perfect fits for this segment, so we deemed the MEC the most competitive fit), 2018 Nissan Rogue, 2018 Subaru Forester, 2018 Toyota RAV4 and 2018 Volkswagen Tiguan. We can update this comparison as more information about 2019 models is released, most notably the Forester and RAV4. Now, there are certainly some models that are smaller (Nissan Rogue Sport) or larger (Kia Sorento) that could also be considered, but we figured it was wise to stick with those in this sweet spot of comparable size and price. We also included links to Autoblog reviews, buying guides and smaller comparisons. Engines and Transmissions With rare exception, this segment features four-cylinder power. Sometimes it's turbocharged, often its not, but standard engine outputs are generally in the same ballpark. Therefore, we'd recommend focusing on torque output, as it's what will make a difference around town or when passing, and weighing that versus fuel economy (the Chevy Equinox, GMC Terrain, Honda CR-V and Mazda CX-5 make particularly strong cases in this regard). Many drivers aren't too fond of continuously variable transmissions (CVT), either, so that's another thing to consider and note during a test drive. As you can see, several models are available with performance upgrades. Besides the Jeep Cherokee's available V6, all are more powerful turbocharged four-cylinder engines. The exception to this would be the Honda CR-V and Ford Escape, as their 1.5-liter turbo engines don't prioritize performance. Instead, they serve as overall upgrades to the base naturally aspirated engines standard on only their base trim levels (CR-V LX and Escape S).

This P-51 Mustang replica flies with a Honda Odyssey engine

The legendary WWII P-51 Mustang fighter ranks right up there with hot dogs, baseball, and apple pie. So sought after is the original Mustang that one of the 200 or so airworthy P-51s left will run you at least $1.5 million. That's why there's a thriving replica market with three-quarter-scale aircraft like this Titan T-51D Mustang. It looks every bit the part until you crack open the cowling and find not a howling Rolls-Royce Merlin V12, but the V6 from the Honda Odyssey minivan. To be precise, the Titan T-51 uses Honda's J35A6 60-degree SOHC V6. It's one version of the ubiquitous J-series engine, found in the Odyssey minivan as well as the Honda Pilot. Other variations of the Ohio-built powerplant pull duty in the Accord and several Acura models. But why a Honda V6? Titan Aircraft president John Williams says the company began production of the T-51 with a Rotax 912F four-cylinder boxer engine, but its 100-horsepower output wasn't cutting it for customers. They wanted "more power and more noise." So the search began for a lightweight, easily-packaged V6, leading first to a Suzuki 2.5-liter with 160 hp. "Our guys still wanted more power, so the next choice was either going to be a Chevy V8 or a Honda V6. The Honda is a little bit lighter and from a V6 standpoint, it's a brute. In the Honda Pilot or the Odyssey, it's rated from 240 to 250 horsepower," Williams explains. Converting the V6 to an airworthy powerplant requires minor modifications, such as swapping the stock engine control unit (ECU) for an aftermarket one. Car-specific parameters for things like anti-knock sensing and rev limiters simply don't work well in the air. "You don't want your timing retarded when you're trying to clear a tree," Williams chuckles. With a hotter Acura camshaft and exhaust modifications, the naturally aspirated Honda engine makes about 300 hp in the T-51D, Williams says. The V6 mates to a custom gearbox designed to yield a 2-to-1 reduction for the propeller. Rather than the original Mustang's crankcase oil, the Titan's nosecase uses automotive gear oil. And while the engine can obviously use regular unleaded from any gas station, it runs well on the 100-octane low-lead aviation fuel commonly found at airports. The T-51 is a kit airplane that buyers can build themselves for less than $100,000. And like most kit manufacturers, Titan offers a builder-assistance program to help with assembly.
