We’ve always liked concept cars, those capture-the-imagination harbingers of the future that tantalize the senses and get us to thinking what driving might look like in the years ahead. No, not the trivial ones that explore nonsensical designs that will, and should, never come to pass. We’re talking hand built concepts that push us to consider their attendant innovations and eye-candy design, and of course their possible production intent. Mazda’s Iconic SP is one such concept.
Presented in a vivid Viola Red to accentuate the car's shape and bodylines, the Iconic SP's bold design, execution, and vision get the blood pumping as one imagines life behind the wheel of this sleek and sinewy sports car. Now, according to reports, this concept may well be heading toward reality. Color us intrigued.
Unveiled at the Japan Mobility Show last year, the Iconic SP clearly illustrates that Mazda still knows how to tantalize the senses with iconic sports car design. Most notably, it did this in the past with its RX-7 and its continuing favorite, the ever-popular Miata. Both of these models created a sensation with buyers from the start. While the RX-7 is now a part of automotive history (with the RX-8 never catching on in the same way), the Miata remains as a cornerstone sports car for the masses that’s popular on the street and on the track for amateur racing.
With the Iconic SP, Mazda leans far forward with this lightweight sports car’s low-slung stance, sensuously flowing lines, and exotic scissor doors. While the concept clearly suggested the potential for a future model at its unveiling, we would imagine its more complex scissor doors could fall by the wayside in a production model as a nod to cost, manufacturability, and mainstreaming this sports car for a larger audience. It’s not that intriguing door designs like this can’t be done. It has been in many instances throughout the automotive timeline with variations on models the likes of the BMW i8, Tesla Model X, Lamborghini Countach, and many others. It’s just that it isn’t likely in the scheme of things.
Worth noting is that Mazda aims the Iconic SP in a green direction with the concept’s scalable two-rotor Wankel engine said to exclusively generate electricity to augment battery power for the car’s electric motors. Heading in this direction seems a natural since series hybrids, or extended range electric vehicles, are increasingly seen by automakers as an attractive option to battery electric vehicles at this point in time.
That said, this isn’t a sure thing. Rumors are flying about from seemingly credible sources that point to different, and perhaps multiple, propulsion strategies. Those include parallel hybrid and all-electric notions of how the car should be motivated. That powertrain vagary makes sense this early in the game since a production Iconic SP – should one actually come to pass – will certainly address the needs and whims of the market closer to a launch date.
Interestingly, Mazda has teased the potential for running the car’s front midship rotary engine on a zero-carbon fuel like hydrogen, something this automaker has experimented with for some time, including with the RX-8 RE developmental vehicle that Green Car Journal editors drove in earlier years. Clearly, offering a variant of this sports car on zero-carbon hydrogen would make the equation all the more compelling.
The world’s automakers have long pursued diverse alternative fuel technologies for good reason. Simply, the future of transportation may well unfold in surprising ways. Among the many advanced fuels explored has been hydrogen, and in fact, even amid today’s focus on battery electric power there continues to be significant interest in this zero-carbon fuel. Here’s a look at the amazing developmental work that BMW was conducting on hydrogen vehicles 18 years ago, as documented in Green Car Journal at the time. We lend perspective on the BMW H2R hydrogen vehicle’s evolutionary importance by presenting this article just as it ran in Green Car Journal’s Winter 2004 issue.
Excerpted from Winter 2004 Issue: In the quest for environmental leadership, there’s often a delicate balancing act as designers strive to create cars that are environmentally positive, yet offer the features drivers most desire. Clearly, core values must remain in focus during the process to retain the values and identity that distinguish carmakers from their peers.
This has been BMW’s mission over the past decade as it has pursued hydrogen cars and the performance to go with them. You can’t, after all, lay claim to the title “ultimate driving machine” if your zero-to-sixty times are glacial and you slog through corners, even if powered by clean-burning hydrogen.
For years, BMW has been refining the liquid hydrogen fueled sedans that it has placed in field trials on multiple continents, championing the use of hydrogen in conventional engines in lieu of the more popular fuel cell. These hydrogen vehicles have improved over the years, making the most of renewable hydrogen fuel in their internal combustion powerplants.
Now, this automaker is putting its stamp on the hydrogen record book with adaptations of this hydrogen engine technology, fielding a land speed record car that has passed the 185 mph mark and claimed an additional eight records as well. Along the way it has achieved recognition by the Federation Internationale de l’Automobile as the fastest hydrogen car in the world.
A distinction achieved at the high-speed Miramas Proving Grounds in France, BMW’s 285 horsepower H2R hydrogen car was propelled to 100 km/h in about 6 seconds, setting records in the flying-start kilometer; standing-start ½ kilometer, kilometer, and 10 kilometers; flying-start mile; and standing start 1/8 mile, ¼ mile, mile, and 10 miles. The record car was piloted by BMW works drivers Alfred Hilger, Jörg Weidinger, and Günther Weber, who took turns at the wheel of the H2R during their record-breaking session.
The sleek and imposing car was conceived, designed, and developed by the automaker’s subsidiary, BMW Forschung und Technik GmbH. Its carbon fiber exterior was designed by DesignworksUSA, the California-based strategic design consultancy owned by BMW Group. This is the same design house that worked on the BMW E1 and E2 electric car prototypes in the early 1990s.
This BMW is motivated by a 6.0-liter V-12 engine modified to run on hydrogen, a gasoline powerplant normally found in the automaker’s 760i model. Among the engine modifications is a fuel injection system adapted to handle hydrogen, which uses injection valves integrated into the intake manifolds. Special materials are also used for the combustion chambers. Liquid hydrogen is carried in a vacuum-insulated, double-wall tank that’s fitted next to the driver’s seat.
Is the H2R just a whimsical exercise? Nope, it’s part of a larger vision. In fact, BMW plans to launch a dual-fuel 7 Series that will run on hydrogen or gasoline, sometime during the production cycle of the present model, surely at a price far lower than that of a hydrogen fuel cell vehicle. Exercises like the H2R help pave the way.
Many believe hydrogen to have the greatest potential of all alternative fuels, not only for vehicles but as a primary energy source for all aspects of life. Used in fuel cells to electrochemically create electricity for powering a vehicle’s electric motors, hydrogen produces no emissions other than water vapor and heat. There are no CO2 or other greenhouse gases.
While hydrogen is largely extracted from methane today, there are bigger things on the horizon. Hydrogen is a virtually unlimited resource when electrolyzing water using solar- or wind-generated electricity, a process that splits H2O (water) into hydrogen (H) and oxygen (O) molecules. Water covers much of the Earth’s surface and is the most abundant compound on the planet.
This has been on the mind of auto manufacturers for years. In fact, editors have experienced many test drives of prototypes and concepts running on hydrogen power for years, like our time behind the wheel of a Mazda MX-5 Miata concept more than two decades ago, along with others from BMW, Ford, GM, Honda, Hyundai, Mercedes-Benz and more.
Along with their own independent hydrogen vehicle development programs, some automakers like GM and Honda are working cooperatively to develop next-generation fuel cell systems and hydrogen storage. Others are working with hydrogen fuel suppliers and state governments to develop an expanded hydrogen fueling network.
In recent years, Honda has been leasing its FCX Clarity fuel cell sedan to limited numbers of consumers in California and Hyundai has recently followed suit with its Tucson Fuel Cell crossover vehicle, also available to limited numbers of consumers in California where hydrogen refueling is more readily available. Both Honda and Toyota have announced plans to introduce next-generation production fuel cell vehicles for consumers shortly.
As with any game-changing technology, hydrogen vehicles come with their challenges. Hydrogen vehicles are presently quite costly to produce, although their cost to consumers who lease them will surely be subsidized by manufacturers until this field matures. The production of ‘green’ hydrogen through electrolysis and other means is also presently limited and costly, plus the nation’s hydrogen refueling infrastructure is extremely sparse, although growing.
The hydrogen vehicle field continues to evolve. A recent study by Sandia National focused on 70 gas stations in California – the state with the largest number of existing hydrogen stations – to determine if any could add hydrogen fueling based on requirements of the 2011 NFPA 2 hydrogen technologies code. The conclusion is that 14 of the 70 stations explored could readily accept hydrogen fuel, with an additional 17 potentially able to integrate hydrogen with property expansions. In this light, expanding the network of hydrogen stations may be more straightforward than previously thought.
Even amid these challenges, with major commitments from automakers like Honda, Toyota, GM, and others in Europe and Asia, hydrogen vehicles are a very real and exciting possibility for the road ahead.
