    GM's SURUS Combines Hydrogen and Autonomous Tech

    General Motors has brought back a concept idea from their past for the modern era. This is SURUS (Silent Utility Rover Universal Superstructure) which takes the hydrogen skateboard platform from the GM Autonomy and Hy-Wire concepts from the early 2000s and supersizes it.

    The platform uses GM’s new Hydrotec fuel cell system that is comprised of a gen 2 fuel cell, storage tank that can provide a range of 400 miles, electric drive units, and a lithium-ion battery. This is placed onto a commercial truck chassis that will allow it handle various tasks and terrains such as military transport or a mobile medical unit in an area after a natural disaster. The platform also features autonomous tech.

    “SURUS redefines fuel cell electric technology for both highway and off-road environments. General Motors is committed to bringing new high-performance, zero-emission systems to solve complex challenges for a variety of customers,” said Charlie Freese, executive director of GM Global Fuel Cell Business.

    GM will be showing off SURUS fall meeting of the Association of the United States Army (AUSA) from October 9th to 11th.

    GM Outlines Possibilities for Flexible, Autonomous Fuel Cell Electric Platform

    Washington, D.C. — General Motors aims to solve some of the toughest transportation challenges created by natural disasters, complex logistics environments and global conflicts. The company will display its Silent Utility Rover Universal Superstructure (SURUS), a flexible fuel cell electric platform with autonomous capabilities, at the fall meeting of the Association of the United States Army (AUSA) from Oct. 9-11, 2017. The commercially designed platform could be adapted for military use.

    SURUS leverages GM’s newest Hydrotec fuel cell system, autonomous capability and truck chassis components to deliver high-performance, zero-emission propulsion to minimize logistical burdens and reduce human exposure to harm. Benefits include quiet and odor-free operation, off-road mobility, field configuration, instantaneous high torque, exportable power generation, water generation and quick refueling times. 

    Fuel cell technology represents a key piece of General Motors’ zero emission strategy. It offers a solution that can scale to larger vehicles with large payload requirements and operate over longer distances. SURUS was designed to form a foundation for a family of commercial vehicle solutions that leverages a single propulsion system integrated into a common chassis. The SURUS platform is equally well-suited for adaptation to military environments where users can take advantage of flexible energy resources, field configurability and improved logistical characteristics.

    GM is evaluating multiple applications for SURUS, such as:

    • Utility trucks
    • Mobile and emergency backup power generation
    • Flexible cargo delivery systems
    • Commercial freight
    • Light- and medium-duty trucks, improving upon the Chevrolet Colorado ZH2 that has been evaluated by the U.S. military under guidance of the U.S. Army Tank Automotive Research, Development and Engineering Center (TARDEC) and is undergoing testing on bases
    • Future military-specific configurations

    SURUS will deliver highly mobile autonomous capability and agility in unpredictable terrain. Operating multiple vehicles in a leader-follower configuration could reduce manpower needed. For future potential military uses, the system’s inherent low heat signature and quiet operation offer benefits in environments to reduce detection and risks. TARDEC has been in discussions with GM evaluating the commercial SURUS concept as a next step of the broader collaboration to evaluate fuel cell technology for future military applications.

    “SURUS redefines fuel cell electric technology for both highway and off-road environments,” said Charlie Freese, executive director of GM Global Fuel Cell Business. “General Motors is committed to bringing new high-performance, zero-emission systems to solve complex challenges for a variety of customers.”

    The SURUS platform leverages GM’s vast experience in fuel cell technology, high-voltage batteries and electric drive systems, autonomous driving and vehicle manufacturing. The platform boasts:

    • Two advanced electric drive units
    • Four-wheel steering
    • Lithium-ion battery system
    • Gen 2 fuel cell system
    • Hydrogen storage system capable of more than 400 miles of range
    • Advanced propulsion power electronics
    • GM truck chassis components
    • An advanced, industry-leading suspension

    Hydrotec Technology

    The SURUS commercial platform draws on GM’s more than 50 years of research and development of fuel cell technology. The scalable and adaptable technology enables land, sea and air applications across commercial and military environments.

    Since April 2017, the Army has been testing the commercial Chevrolet Colorado ZH2 on its U.S. bases to determine the viability of hydrogen-powered vehicles in military mission tactical environments. The vehicle has been operating in off-road conditions to evaluate its power generation, reduced odor, acoustic and thermal signatures, high wheel torque, extended operating range and the potential to use the byproduct water.

    Military testing has shown the ZH2 reduced acoustic non-detection distance by 90 percent compared to current military vehicle in operation. This means the ZH2 can get 10 times closer before being detected. Leaders also observed the potential advantages for stationary power generation over diesel generators, including a significant reduction in idle noise and fuel use. Testing will continue through spring 2018.

    Partnerships remain an important part of GM’s electrification strategy. Last year, the U.S. Navy unveiled a GM fuel cell-powered Unmanned Undersea Vehicle (UUV) for testing purposes that leverages GM fuel cell technology common with the Colorado ZH2.

    Cool tech, yet with that said, Hydrogen is an Energy looser as it takes more energy to produce hydrogen fuel than other solutions.

    I can see a CNG generator to produce kWh of juice for a pure EV platform. To me that would be more realistic I think.

    Be interesting to see what they want to really use this for besides the stated uses above.

    I will say that the Medical Unit and the Container hauler in a shipping yard are very cool autonomous uses of this tech.

    Fuel cell is going no where, waste of money to even bother with it.  Developing better batteries is the break through.    Toshiba says they will have a battery in 2022 that can get 300 miles of range in 5 minutes of charge.  That is the stuff to work towards.  Even most gasoline cars don't have 300 miles of range in 5 minutes of pumping gas.

    Agree that I would not waste money on the tech either, but it is understandable as GM and Honda have teamed up to spend 85 million on the tech in support of the EPA and US Military that is funding the research.

    I would say that the bulk of GM's announcement is really focused on EV and they will keep a few hundred peeps working by spending the tax dollars from the two gov agencies to show what can be done.

    This DOES NOT mean it is economically feasible.

    What GM needs is an electric version of that platform so that it can sell real EV cars and crossovers for real $$$$.  Fuel cells might be good in theory, but may well be impractical.

      Current-gen Mazda 3 sedan ... driven for a week ... it has been a long time since I've driven any Mazda

      By trinacriabob · Posted

      This rental experience, lasting one week, was a surprise all the way around.  The first thing that comes to mind is how helpful the agents were upon renting and returning the vehicle. I got my assigned category of vehicle, plus a small upward bump, assuming this sedan could be considered midsized.  The current Mazda 3 sedan appears to have grown up and, with its thicker pillars and haunches, looked like it was going to be a nicer car for an entire week than the only other time I’ve rented a Mazda 3, about 5 years ago, and for which that rental lasted only 1 day. Do I like the way the current Mazda 3 looks?  Mostly yes, and some no.  I like the flow of the silhouette and, to some extent, the definition of the volumes.  The side profile is attractive enough.  The same could be said for the rear fascia and taillamp assembly.  However, I’m not a fan of the trademark too tall grille for this size of car. Its Mazda’s current vernacular and it probably works a little better on their larger vehicles, but this is just my opinion. The Mazda 3’s interior is spartan in its volumes and finishes, almost looking Germanic.  I have different feelings about the instrument cluster than I do the overall dashboard.  The main instrument pod is very clearly and cleanly laid out.  It has 3 main pods, with the center pod, which can be configured in many ways, dominating the others.  The tachometer is to the left and larger and very readable fuel and temperature gauges are to the right.  As for the remainder of the dash, a slightly angled and narrow almost tear drop like infotainment screen is embedded into the cowl.  Ventilation slots are thin and run horizontally.  The climate control panel is workable, but not as visually appealing, and even symmetrical, that other vehicles are currently using.  The steering wheel feels good to the touch, with its materials, but, even with upward seat adjustments, I did not have the command I wanted over the top of the dashboard.  It felt slightly more astronaut or race-car driver-like than I would have wanted.  However, the seating shape is conventional and supportive, so comfort wasn’t as issue.  Seating is neither too cushy nor too hard.  I did need some extra time to get used to 2 areas in terms of using settings.  The first was that the infotainment display was not a touch screen, but one operated by a large dial sitting right behind the gear selection lever.  It was not that intuitive and it would lead me to return to the home setting to try again.  The other was the cluster of controls on the left side of the steering wheel.  In some of the audio controls, there was too fine of a line between tabbing up or down or pushing into it.  At times, I didn’t get the intended result I was looking for. The Mazda 3’s forte seems to be its handling.  It inspired some confidence and, as I found myself on some expressways with a legal speed limit of 75 mph, I noticed that quickly changing lanes and the feeling of being in control were both very good.  However, in this niche, I’ve had vehicles that were quieter and more isolated.  I remember the last-gen Mazda 3 of a handful of years ago as being both grainy in its engine and busy as it rode on washboard pavement.  This one is much improved.  However, there is the engine hum, which some may like, and maybe a marginally higher amount of road noise or tire thum coming through than in some of its current competitors.  When you put your foot into it, it definitely makes itself heard, albeit as a rhythmic purr.  The engine is a 2.5-liter 4-cylinder, a displacement that was once so common, and it is naturally aspirated.  The transmission is a 6-speed geared automatic.  Shifts were clean and, consistent with the other communication from its mechanical aspects to its driver, shifts 1-2 and 2-3 were felt, though not at all unpleasant, in normal to spirited driving.  Even some step-gear and DSG transmissions have gotten to the point where they seemingly “slush” into the next gear.  While I might like drivability that is even quieter and more isolated, I appreciated a 2.5-liter 4-cylinder engine and a 6-speed automatic transmission instead of a CVT.  The reliability of Mazda powertrains is supposedly good. Even though the cabin front position is low for my taste, the seats are supportive and there is enough leg room, though it’s also a little more work to get into and out of the car.  Rear seat legroom seems acceptable for medium-height adults, albeit probably not so much for tall people.  The somewhat thicker rear pillar does not impede visibility when turning one’s head toward the rear.  Visibility through the greenhouse is workable and, in concert with the Mazda 3’s styling, is appealing.  Trunk space is also good for the Mazda 3’s size and the split folding rear seats make it even more generous. I did not calculate the Mazda 3’s fuel economy.  Compared to a smaller 4-cylinder displacement and a CVT, the fuel needle moved a little more quickly, but, also, the vehicle does not come with a very large tank.  It also did not spin at lower rpms while maintaining highway speed, with some vehicles in the same niche now cruising along at, say, 1800 rpms, either because of more gears or a CVT.  I’d say I was noticing slightly over 2000 rpms when maintaining highway speed.  Still, it got acceptable fuel mileage. It did not affect what I was going to write, but I did glance at professional reviewers’ opinions on the Mazda 3.  Most are very pleased with the vehicle.  Again, I thought it was competent, and I really appreciated its road manners and its feeling planted but liked, instead of loved, most of the other aspects of its drivability and its features. However, it’s worth taking note of the Mazda 3’s price point and good record.- - - - - - PHOTOS FORTHCOMING

      Big question is what version of Supercharging will Tesla put in here as they seem to be bloody slow at rolling out V4 chargers to compete with EVgo, Chargepoint, Electrify America, etc. Tesla strikes sweeping deal to install Supercharger stations outside of popular fast food chain
