NOx, Hydrocarbons and Worse – What’s Else is Coming from your Exhaust Pipe?

As automotive consumers, we think we’re pretty well informed. We read all the blogs and all the magazines, pouring over the all important numbers: 0 to 60 times, miles per gallon and – increasingly – CO2 emissions. That last one is interesting, as it’s only come to the mainstream public’s attention in the last seven years or so. Anyone would think that the only noxious chemical cars put into the atmosphere are CO2, but you’d be wrong.

Nitrogen oxides (NOx), hydrocarbons, diesel particulates and carbon monoxide are also put out by our daily drivers. Think of the worst parts of cigarette smoke and the fumes from burning plastic and you’ll have a good idea what I mean. Premature births, lung cancer and smog – all attributable to these noxious chemicals.

You may be surprised at the vehicles that are very good on CO2 and very bad on NOx and hydrocarbons. By adding the two together, we get a milligram per kilometre rating. So here are the best and worst from the UK’S Vehicle Certification Agency:

UK's best performers

Skoda Yeti 1.2 105PS 49mg/km

Nissan Qashqai+2 2.0 71mg/km

Honda Insight 1.3 IMA S/SE 73mg/km

Porsche Cayman S 3.4 79mg/km

Honda Insight 1.3IMA ES-T 5dr 82mg/km

UK's worst offenders (mg/km)

Nissan Pathfinder 2.5 dCi 190 1,150mg/km

Seat Ibiza SC 1.2 12v 70PS 1,026mg/km

Citroën C5 1.6i THP 1,010mg/km

Audi A4 3.2 FSi Multitronic 999mg/km

Mercedes B-Class B160 BlueEfficiency 994mg/km

Would you believe that a 2.5L Volvo V70 estate is in some ways better for the environment than a 1.3L Fiat 500 with start-stop engine tech? Try 201mg/km versus 484mg/km. And would you of guessed a Porsche Cayman S would be, in one way at least, better for the environment than a Mercedes-Benz B160 BlueEfficiency?

It just goes to show that the more you know the better off you are. One can only hope that, in time, these details will appear on the same stickers that tell us mpg and CO2 emissions so car buyers can make a fully informed choice.

GM Building Parts for Chevrolet Volt from BP Oil Spill Booms

The new Chevrolet Volt extended-range electric car is doing its part in improving the environment by making the best use of the oil that was spilled into the Gulf of Mexico from the BP Deepwater Horizon rig. To explain, General Motors has began recycling oil-soaked plastic booms from the notorious spill into components for the Volt.

The Detroit-based automaker said it has developed a method to convert an estimated 100 miles of the material off the Alabama and Louisiana coasts into more than 100,000 pounds of plastic resin that will be used for parts that deflect air around the vehicle’s radiator.

These parts are comprised of 25 percent boom material and 25 percent recycled tires from GM’s Milford Proving Ground vehicle test facility, with the remaining percentage covered by a mixture of post-consumer recycled plastics and other polymers.

“Creative recycling is one extension of GM’s overall strategy to reduce its environmental impact,” said Mike Robinson, GM vice president of Environment, Energy and Safety policy. “We reuse and recycle material by-products at our 76 landfill-free facilities every day. This is a good example of using this expertise and applying it to a greater magnitude.”

If GM hadn't used the oil-soaked booms for parts, they would have been incinerated or sent to landfills.

“This was purely a matter of helping out,” said John Bradburn, manager of GM’s waste-reduction efforts. “If sent to a landfill, these materials would have taken hundreds of years to begin to break down, and we didn’t want to see the spill further impact the environment. We knew we could identify a beneficial reuse of this material given our experience.”

According to the automaker, the ongoing project is expected to create enough plastic under hood parts to supply the first year production of the new Chevy Volt.

Super Green: The New Wave Of Environmentally Conscious Exotic Supercars

It's not that easy being green, least of all if you're a builder of exotic, high performance supercars or uberluxury sedans. Recently however, there has been a move towards improving fuel economy and reducing emissions by many of the world's biggest and most well known luxury and performance brands.

Take Ferrari's stop-start equipped California HELE or Mercedes-Benz's SLS AMG E-Cell concept, for instance. And there's more on the horizon, including the plug-in hybrid 918 Spyder from Porsche and BMW's Vision EfficientDynamics, the latter of which allegedly will offer M3 performance with a CO2 emissions rating of just 99 grams per kilometer.

And it's not just these four who are in it for the environmental crowd cred: other makers including Lotus, Audi, Lamborghini, Jaguar and Bentley are also looking to green up their model ranges.

This comes as no surprise to Christoph Stuermer, an analyst at IHS Automotive in Frankfurt:

"These upper-end, high-performance cars have always been examples of the best car technology out here, and being green is now part of being technologically advanced They have to come up with something so as not to be seen as technical dinosaurs."

Enrico Galliera, the commercial and marketing senior VP at Ferrari, agrees that it's definitely something that the company's customers are all for:

"When you consider buying a Ferrari, you're considering it for the performance. At the same time, when we approached customers and said, 'Here's a way you can still have that and be greener,' the reaction was extremely positive."

So there you have it. Now you can have your cake and eat it too, though you'll have to pay for the cake part first. And with prices around €180,000 (US$252,376) for the California HELE and an expected €500,000 (US$682,260) for the 918 Spyder that is one expensive, green frosted cake.

PS: Metaphors aren't my strong point...

Philadelphia High School Students Build Automotive X Prize Contender [with Videos]

Some people are just meant to go places. In the case of 16-year old Azeem Hill and the rest of Simon Hauger's West Philadelphia-based high-school hybrid team, that place is somewhere into the vastly expanding world of alternative fuel technology.

The West Philly Hybrid X Team, builders of the EVX GT and EVX Focus, is the result of an after-school program at the Academy of Automotive and Mechanical Engineering meant to educate youth about the future of hybrid tech and transportation. What's more impressive is that this young underdog team was in the running for this year's Automotive X Prize.

After besting some really heavy hitters (like MIT, for one), the EVX team was eventually disqualified. Still, let's give a digital round of applause to these guys for going out there and doing the damn thing with the big boys.

Azeem and other members of the program started out at ground level and learned everything necessary in order to create a hybrid car with the goal of returning 100 mpg in the city, 70 mpg on the highway, and still being able 60 in under 5 seconds. Check out the vids below to learn a little more about the program and its goals.

Volvo wants in on the EV Business, Starts Developing C30 DRIVe Electric with Fuel-Cell Range Extender

With even the likes of Porsche going green – not to mention the Chevrolet Volt or the Nissan Leaf, it's no surprise that Volvo wants a piece of the "Look at me, I'm saving the planet!" action.

They partnered up with Powercell Sweden AB (with backing from the Swedish Energy Agency) and hope that the Volvo C30 DRIVe Electric will be ready for testing on the road by 2012.

"This is an exciting expansion of our focus on electrification. Battery cost and size means that all-electric cars still have a relatively limited operating range. Fuel cells may be one way of extending the distance these cars can cover before they need to be recharged" Volvo Cars President and CEO Stefan Jacoby said. "What is more, the project gives us increased knowledge about fuel cells and hydrogen gas".

The project is in its early stages, the focus being on the range of the car. And it's no surprise, as no EV can stand a chance these days if it can't go at least 40-60 miles on one charge.

To achieve this, Volvo is cooking up -wait for it- a Range Extender. A reformer, tasked with breaking down liquid fuel and creating hydrogen gas. This gas then goes into the fuel cell and gets converted to electrical energy powering the motor.

The advantage of the process is that it's creating electricity without any emissions of carbon oxide (CO), nitrogen oxides (NOx), sulphur oxides (SOx) and particles whatsoever. On other thing is that the reformer can just as easily break down renewable fuels, like ethanol.

Volvo expects the Range Extender to, well, extend the range of the car by up to 250 kilometers (155 miles), in addition to the range provided by the battery pack.

Credo E-Bone has Funny Name, Bulbous Styling and Hydrogen Power

In the future, we will all ride around in hydrogen fueled plastic caterpillars. Or at least we will if Hungarian industrial design Peter Simon has his way. His vision for a greener public transport future is a hydrogen fuel cell - electric bus called the Credo E-Bone [is it just me, or does "E-Bone" sound like something you'd buy at an adult shop and plug into your USB port?].

The Credo E-Bone is a zero emission vehicle with a bone-like internal structure and lightweight composite plastic body. There is an electric motor driving each wheel which is presumably powered by the lithium batteries in stop-start driving and the hydrogen fuel cells on the highway. The fuel cells / batteries are stored on the roof.

For all my chiding, I do have to give Peter Simon some credit. If you square off the window- and roofline, do away with the curvy rear glass and wheel covers and replace the hydrogen fuel cells with natural gas, you come up with a very practical proposal. Not a very imaginative proposal, granted, but one that I could see on our roads within the next two to three years.

Motive Releases First Images of Composite Bodied Kestrel EV

In response to numerous media requests (or so the company claims), small-scale Canadian automaker Motive has released the first official images of its hemp-bodied EV city car, the Kestrel. The car was unveiled at the EV 2010 VÉ Conference and Tradeshow in Vancouver recently.

As previously reported by Carscoop, the Kestrel is a cab-forward design that seats four. It is made of a bio-fibre (hemp) based composite that is said to reduce weight, resist rust and increase impact absorption.

Along with the images, Motive has released further details of the upcoming EV. Weighing in at 1,874 lbs (850 kg), the company optimistically states that the Kestrel will be good for a top speed of 84 mph (135 km/h) and a driving range of 100 miles (160 kilometers) on its lithium-ion battery power.

The Kestrel is said to be just one of the cars in the Project Eve line-up. Project Eve is a consortium of Canadian companies who want to bring electric mobility to Canada, a noble cause. Motive is one of the Project's co-founders.

Nathan Armstrong, Motive's President states, "We believe this is an important step for Canada and are extremely happy to be a part of such an innovative group of companies."

A working prototype of the Kestrel is planned for mid-2011, and with full scale production and commercial sales starting in late-2012.
