OUTSPOKEN :: WHERE ARE WE HEADED?

T

So in the midst of all this, where are we headed? Simple. In the right direction, of course.

here are many outspoken and polarizing proponents of the various fuels and technologies at play today. This has been the case for several decades now and isn’t likely to disappear anytime soon. Many electric car enthusiasts do not see a future for internal combustion or even hydrogen fuel cell vehicles. Hydrogen proponents point out that fuel cell vehicles make more sense than battery electrics since hydrogen generally offers greater driving range and fuel cell vehicles can be refueled in under five minutes, while battery electrics cannot. Biodiesel enthusiasts point out the obvious benefits of this biofuel and even as this fuel gains momentum, wonder why government support isn’t stronger. Natural gas advocates see huge and stable supplies of this clean-burning fuel now and in our future, without the truly significant commitment to natural gas vehicles this should bring. And those behind advanced internal combustion vehicles achieving ever-higher efficiency simply wonder what the fuss is all about when conventional answers are here today. So in the midst of all this, where are we headed? Simple. In the right direction, of course. As I was writing about these very fuels and technologies some 25 years ago, it wasn’t lost on me that the competition for dominance in the ‘green’ automotive world of the future would be hard-fought and long, with many twists and turns. As our decades-long focus on the ‘green car’ field has shown us, the state-of-the-art of advanced vehicles in any time frame is everchanging, which simply means that what may seem to make the most sense now is likely to shift, and at times, shift suddenly. This is a field in flux today, as it was back then. When Nissan introduced its Altra EV back in 1998 as an answer to California’s Zero Emission Vehicle mandate, it turned heads with the first use of a lithium-ion battery in a limited production vehicle, rather than the advanced lead-acid and nickel-metal-hydride batteries used by others. Lithium-ion is now the battery of choice, but will it remain so as breakthrough battery technologies and chemistries are being explored? Gasoline-electric hybrids currently sell in ever-greater numbers, with plug-in hybrids increasingly joining their ranks. But who’s to say that advanced internal combustion engines won’t continue their efficiency march forward in ways that rival hybrid power? It’s no secret that automakers are striving mightily to develop conventionally-fueled combustion engines with new technologies and strategies that eke levels of fuel efficiency only thought possible with hybrid powerplants just a few years ago. Plus, there are all-new answers on the horizon. While only expected in limited numbers and markets, Toyota’s coming 2016 Mirai and Honda’s FCV show that automakers are serious about hydrogen-powered sedans as yet another option for ‘green’ focused car buyers. What drives efficiency – and by extension determines our future path to the high efficiency, low emission, and more sustainable vehicles desired by consumers and government alike – is textbook evolution. Cars are adapting to meet the changing needs of future mobility and the imperative of improved environmental performance. Some of these evolutionary changes are predictable like lightweighting, improved aerodynamics, friction reduction, and enhanced powertrain efficiencies. Other answers, including the fuels that will ultimately power a new generation of vehicles, will be revealed over time. So here’s to the cheerleaders who tell us quite vocally that their fuel, technology, or strategy is the answer to our driving future. One or more of them may be right. But the fact is, the evolutionary winner has yet to be determined.

BIODIESEL AMERICA’S ALTERNATIVE FUEL SUCCESS STORY

THE QUEST FOR an ideal renewable fuel involves many important goals, with special emphasis placed on positive environmental impact and displacing petroleum use. This fuel must function readily in existing engines without sacrificing the performance expected in today’s vehicles. Ideally, it should be primarily produced in the United States to support American jobs and contribute toward energy independence. And, of course, it must be created in sustainable ways to have a lasting and positive impact. That ideal fuel is biodiesel, America’s alternative fuel success story. Produced from diverse feedstocks including animal fats, recycled cooking oil, and soybean oil, biodiesel is a high-quality diesel replacement that reduces tailpipe emissions and offers important environmental advantages. In fact, the California Air Resources Board recently affirmed that biodiesel reduces greenhouse gas emissions by at least 50 percent and often by as much as 81 percent compared to petroleum. This finding confirms biodiesel’s advantage as the fuel with the best carbon score among all liquid fuels.

DIRECTIONS :: PERFORMANCE: DOING MORE WITH LESS

S

ome cars leave an impression that lasts a lifetime. The Ford Mustang is one of those cars for me. As a kid, I was blessed with a dad who always had something unique in the driveway, from a Morris Minor to a

Triumph Herald. None were exotic or expensive, but they were fun and more than a little quirky. So, when the first generation Mustang came out, Dad had to have one and in the summer of 1964 there was a 1964 1/2 Mustang convertible in our driveway. It was copper with a white interior and white top, powered by a 289 V-8 and a ‘three-at-theknee’ shifted manual transmission. Detroit was producing big iron at the time and this car seemed lean, efficient, and mean. Many happy hours were enjoyed in that first generation Mustang. When Ford offered to let me drive a new Mustang not long ago, I was understandably thrilled. Then I read the specs. The car would be a four-cylinder with an automatic transmission. No, really? If you want to know how far the automotive industry has advanced in the last 50 years, go drive the new 2.3-liter EcoBoost four-cylinder Mustang. For those of us of a certain vintage let me clarify, this is not a Pinto engine. This 2.3 is

If you want to know how far the automotive industry has advanced in the last 50 years, go drive the new 2.3-liter EcoBoost four-cylinder Mustang.

a beast. The first time I pushed the start button, the raspy growl made it clear that the EcoBoost means business. This engine produces 310 horsepower and 320 lb-ft torque. At just 137.5 cubic inches it’s less than half the displacement of Dad’s 289 V-8. For perspective, consider that this new four-cylinder also makes more horsepower than the 2005 Mustang GT 4.6-liter V-8 of just 10 years ago. EcoBoost uses smaller, more efficient engine designs aided by turbocharging to do more with less. It’s not a new idea, but Ford has been refining it for years with impressive results. The 2.3 Mustang engine uses a twin-scroll turbo with split exhaust runners to feed immediate boost. It produces low-end power more like a V-6 or V-8 than a four, delivering a very satisfying driving experience. I’ve always preferred manual transmissions, but the six-speed auto in the Mustang was quite nice. It can be manually shifted with paddle controls on the steering wheel for more control and fun. The best part about this whole equation is that the EcoBoost engine is lighter than V-6 and V-8 counterparts. That makes all vehicle dynamics simply work better. Everything from acceleration to handling and braking are improved. The car literally feels lighter and is more nimble, which makes it a joy to drive. Now for the ‘green’ part. The EcoBoost Mustang has an EPA highway fuel economy rating of 32 mpg. This car is quick and will spring from 0-60 mph in 5.6 seconds. But we also decided to push it in the other direction and see how it would do in economy cruise mode. At legal speeds, mid-to upper 30 mpg averages are easily obtainable. You can use this car as a daily commuter and not break the bank. It’s an interesting and compelling contrast to look back 50 years to the first Mustang, and even 10 years to the last generation Mustang. But what I love most is that this iconic car still has swagger and will stir emotions. I’ll take that over an automotive appliance any day. – Todd Kaho Green Car Journal Issue No. 42 9

10 THINGS TO KNOW

ABOUT BMW’S INNOVATIVE i3 B Y

T

R O N

C O G A N

he BMW i3 is far from just another electric car. While it shares certain things in common with other electrics like the ability to drive on battery power, zero localized emissions, and the capability of charging at home or at public charge

stations, there’s much more to the story. This milestone car is the direct result of BMW’s Project i, a far-reaching initiative launched in 2007 to develop sustainable answers for driving in crowded urban environments. The i3, called BMW’s Megacity Vehicle during much of its development, benefited from this initiative’s extensive research, development, and technology demonstration projects. These global activities focused on learning about consumer preferences, driving habits, and real-world use, details important to the development of the i3. Here are 10 things you should know about BMW’s innovative electric i3, Green Car Journal’s 2015 Green Car of the Year®.

28 Green Car Journal Issue No. 42

BORN ELECTRIC is an apt description for BMW’s i sub-brand. From its conception, the i3 was designed, engineered, and built to be an electric vehicle. This clean sheet approach means each and every part of the i3 could be focused on its mission without the compromises often required in adapting electric propulsion to a shared internal combustion platform. Batteries, control systems, and other components unique to an electric vehicle go where they’re designed to go without intrusion, rather than where they can fit in an existing model.


LIFE/DRIVE ARCHITECTURE is the underpinning for the innovative i3. The Life Module, or passenger cabin, is built from Carbon Fiber Reinforced Plastic (CFRP). CFRP used for the Life Module is 30 percent lighter than already-lightweight aluminum. The i3’s Drive Module, constructed of 100 percent aluminum, integrates the car’s electric drivetrain, lithium-ion battery, suspension, and structural components. The combination of lightweight CFRP and aluminum in the Life/Drive architecture increases efficiency while providing excellent occupant protection.

REAR COACH DOORS are a unique feature of the i3. Unlike conventional door designs with a center body pillar between the front and rear doors, the i3’s innovative coach door design finds rear doors opening on rear-mounted hinges. The absence of a center pillar provides unparalleled access to the car’s cabin. Another important benefit is that coach doors, combined with the i3’s low console and absence of a transmission tunnel, enable a ‘slide-through’ experience that allows exiting on the passenger’s side in busy urban environments.

VERSATILE INTERIOR space and functionality make the fourpassenger i3 feel spacious for its right-sized urban design. Controls and displays are intelligently placed for ease of use. Raised ‘semicommand’ seating provides for a better view of traffic and surroundings, an especially welcome feature when driving in crowded urban environments. While the i3’s compact form aims at efficiency and urban maneuverability, it does not sacrifice functionality along the way. With rear seats folded down it can handle up to 38.8 cubic feet of gear or cargo.

SUSTAINABILITY is an important element in the i3. Its Carbon Fiber Reinforced Plastic is manufactured in Washington State with renewable hydroelectric power. More than 10 percent of the CFRP used is recycled material. Fibers from the Kenaf plant are used for the instrument panel surround while Eucalyptus used in the dashboard is sourced from responsible forestry. Some 25 percent of the thermoplastic parts used on the exterior, and 25 percent of the plastics used in the interior, are made from recycled materials or renewable sources.

CHARGING the BMW i3 is convenient. Owners can install a 220-volt Level 2 charger at home to fully charge an i3 in about three hours, with this same capability at public chargers. Locations where SAE DC Combo Fast Charging is available can charge up to 80 percent in 20 minutes and 100 percent in 30 minutes. BMW is working with strategic partners to expand fast-charging locations along transportation corridors on the East and West Coasts. An Occasional Use Cable and charger plugged into a household outlet can charge batteries in about 20 hours.

Green Car Journal Issue No. 42 29


ELECTRIC PERFORMANCE is integral to the BMW i3 experience. Its 170 horsepower electric motor features 184 lb-ft torque that launches the lightweight i3 from 0 to 30 mph in about 3.5 seconds and 0-60 mph in 7.2 seconds. Battery placement that’s low and close to the rear drive wheels enhances traction, with the light weight Life Module effectively lowering the car’s center of gravity. It uses a front MacPherson strut and 5-link rear suspension system. All come together to deliver the dynamic drive experience expected of a BMW.

AVAILABILITY is often an issue with electric cars since many models are sold only in select geographical areas and in very limited numbers. Not so with the BMW i3. From the start, the i3 was designed to be a mass-market vehicle with widespread availability in the U.S. and in countries around the globe. Plus, the i3 can be configured in ways that fit the varying needs and sensibilities of drivers, with Mega World, Giga World, and Tera World trim levels available plus a choice of all-electric battery power or REx range extender capability.

30 Green Car Journal Issue No. 42

ADVANCED ELECTRONICS on board the i3 provide an array of desired driver assistance systems, infotainment, and entertainment features. Of special interest is an ability for these systems to optimize range and facilitate convenient charging. Apps allow sharing information between smartphone and car including vehicle location, driving range, charge level, and charging locations that can be sent to the car. Driver-selectable Comfort, ECO, and ECO PRO+ driving modes enable changing efficiency and performance levels to suit varying driving needs.

RANGE EXTENDER technology enhances driving versatility. Lithium-ion batteries provide an EPA estimated range of 81 miles in the battery electric i3. This capability far exceeds the average 30 miles of daily driving shown in Project i studies, which documented the daily drives of more than 1,000 participants over 12 million miles. The i3 is also available with an optional gasoline range extender that roughly doubles driving range. When the battery gets to a certain level, the range extender generates electricity that maintains battery level for longer drives.
