Nissan to Launch Compact Hybrids

Andrew Williams — Mon, 20 Jul 2009 11:44:19 +0000

Nissan has announced plans to sell compact hybrid vehicles based on its own technology in Japan, starting from 2011.

The Japanese outfit intends to make a low-cost, compact powertrain featuring an integrated electric motor providing supplemental power to the main gasoline engine. Energy will be provided by high-performance lithium-ion batteries.

According to Nissan the hybrids should be more than twice as fuel efficient as the equivalent gas-powered offerings.

Daimler’s First Electric Car

Lisa Wojnovich — Tue, 30 Jun 2009 20:09:55 +0000

Most odd stories relating to the environment tend to revolve around researchers and scientists and their slightly off the wall discoveries. But not so today. Today, in news of the weird — or at least slightly surreal — I bring you Daimler, the German automaker, who announced last week their very first hybrid car, the Mercedes Benz S Class. It’s a limousine.

A Year of Digg: Gas 2.0’s Ten Most Dugg Stories of 2008

Nick Chambers — Sun, 21 Dec 2008 18:43:42 +0000

Editor’s note: Today we inaugurate the first ever best-of Gas 2.0 series with our most Dugg stories of 2008. During the rest of the week look for the most up-voted reddit, most Stumbled, and most viewed stories of year as well. As a special bonus, we’ll finish off the week by handing out the first ever (yet sure to be highly coveted) Gas 2.0 Post of the Year Award.

Ah, Digg. That beautiful beast. There are some who say she even controls the internet as we know it. In her all-knowing and random wisdom, she giveth and she taketh away. Actually, if truth be known, she mostly taketh. Yet when she does giveth, man does she giveth in a huge way. For that we pay her tribute by exposing the loins of her Gas 2.0 grace. Uhhh… ick. Sorry.

So, before I make myself sick, let me present you with a stroll down the Gas 2.0 memory lane.

59 MPG Toyota iQ is Coming To the U.S. As a Scion!

Nick Chambers — Tue, 14 Oct 2008 16:04:36 +0000

Just yesterday I wrote about what I dubbed as “perhaps the ultimate city car,” the 59 MPG Toyota iQ 4-seater. I also bemoaned Toyota for releasing it in Europe but not in the US.

>>> more on the Toyota/Scion iQ

Well, turns out Toyota is bringing the iQ to the US under the Scion badge. Motor Trend, without citing sources, is claiming that the Scion-branded iQ will be shown to the public at the upcoming LA Auto Show next month.

59 MPG Toyota iQ On Sale In Europe, US Plans Unclear

Nick Chambers — Mon, 13 Oct 2008 19:49:15 +0000

Perhaps the ultimate city car for the childless, the Toyota iQ includes all of the safety, comfort, and convenience you’d expect from a larger car, but packaged in the world’s smallest 59 mpg 4-seater.

Before the details fanatics among us get all hot and bothered, the 59 mpg (4.0 liters/100 km) rating refers to the diesel iQ’s combined city/highway fuel economy expressed in U.S. miles but as measured by European standards (base directive 80/1268/EEC, latest amendment 2004/3/EC).

With lower carbon dioxide emissions than the Prius — around 159 grams of CO2 emitted per mile by the 1.0 liter gas engine and 166 g/mile for the diesel version — not only does the iQ deliver on fuel economy, but its straight-up conventional engine is a pollution winner too.

Every Drop Counts: Nissan to Equip Cars with Fuel Efficient ECO Pedals

Anthony Cefali — Tue, 05 Aug 2008 16:25:11 +0000

The 1990’s were the host of many great fads. Furby, Tamagachis, string theory, the examples are as numerous as the many incarnations of Prince. Fast forward to 2008, and it seems that America’s fads are finally becoming practical. Hypermiling is the new hoola-hoop, and it’s even more convenient because there is more than one way to do it. While some prefer drafting and coasting in neutral whenever possible, most drivers just watch their tachometers.

Low Cost Gas Engine Innovation Doubles Fuel Economy

Nick Chambers — Thu, 26 Jun 2008 15:15:02 +0000

Revetec, a little known company from the Gold Coast region of Australia, may be on to something huge: they’ve created an engine that is 50% smaller, 50% lighter, has 50% lower emissions and is cheaper to manufacture than a conventional internal combustion engine of the same horsepower. Oh yeah, did I mention that it doubles the fuel economy too.

What that means is a car like the 2007 Toyota Yaris, which is rated at 40 mpg on the highway, would get 80 mpg with a Revetec engine.

This isn’t some hoax… They have a prototype which has been attached to an actual vehicle and independently tested to substantiate their claims.

Turbine Engine: No Pistons, No Lube, 30% Better Fuel Economy

Nick Chambers — Mon, 09 Jun 2008 16:58:03 +0000

There are more than 5,000,000 heavy duty trucks running up and down US highways each day. Every one of those trucks gets an average of 7 mpg, carries upwards of 200-300 gallons of diesel, and spews out potentially harmful emissions.

Like it or not, we depend on them to bring us our food, fuel, and products for everyday living. It’s a connection that most of us often forget about, only remembering it long enough to curse them as they slow us down on the highway.

It’s also an industry that has recently been hit hard by soaring fuel prices, and now, with the average price of diesel in the US at $4.70/gallon and climbing, it’s sure to get worse.

Needless to say, there’s a rising cacophony of voices within the trucking industry clamoring for relief. Most of this noise currently comes in the form of wanting a break in fuel prices, but really that’s just a temporary fix. Any solution with sticking power would have to offer both economic and environmental benefit — you know, win-win.

Scania’s Ethanol Diesel-Engine, Runs On Biodiesel Too

Clayton B. Cornell — Tue, 15 Apr 2008 20:26:28 +0000

Scania (part of Volkswagen) builds modified, heavy-duty diesel engines designed to run on almost pure ethanol (E95, or 95% ethanol, with a 5% ignition improver).

If that sounds weird, that’s because it is. US auto manufacturers make a big deal out of converting cars and trucks to run on ethanol/gasoline blends of up to 85% ethanol. Scania has done better than that for 15 years, and guess what, their engines can run on 100% biodiesel too, without any modification.

Need a New Car? Nope, Just a New Engine!

Benjamin Jones — Tue, 25 Mar 2008 02:34:01 +0000

Engine Repower is a new service that gives car owners the option of replacing their old, worn out engine with a rebuilt engine of the same vintage instead of simply buying a new car or repairing specific problems. When a first saw this page, I was very interested, as I am a proponent of keeping your car as long as possible to reduce wasteful manufacturing processes, even in the face of promises of lower emissions made by newer cars.

Car Hacker’s Hummer Gets 60 MPG

Clayton B. Cornell — Fri, 14 Dec 2007 18:50:16 +0000

If you haven’ heard of the Motorhead Messiah, Jonathan Goodwin, let me introduce you: he hacks cars for a living, and he can get 60 mpg out of an H3 Hummer while doubling the horsepower and cutting emissions in half. Unbelievable? Yes, but this is no joke, and it’s doesn’t defy the laws of physics either. The hacked H3 is a hybrid with the gasoline fuel system removed. In its place, Goodwin installed a biodiesel-burning jet turbine to recharge the electrical system:

Goodwin leads me over to a red 2005 H3 Hummer that’s up on jacks, its mechanicals removed. He aims to use the turbine to turn the Hummer into a tricked-out electric hybrid. Like most hybrids, it’ll have two engines, including an electric motor. But in this case, the second will be the turbine, Goodwin’s secret ingredient. Whenever the truck’s juice runs low, the turbine will roar into action for a few seconds, powering a generator with such gusto that it’ll recharge a set of “supercapacitor” batteries in seconds.This means the H3’s electric motor will be able to perform awesome feats of acceleration and power over and over again, like a Prius on steroids. What’s more, the turbine will burn biodiesel, a renewable fuel with much lower emissions than normal diesel; a hydrogen-injection system will then cut those low emissions in half. And when it’s time to fill the tank, he’ll be able to just pull up to the back of a diner and dump in its excess french-fry grease–as he does with his many other Hummers. Oh, yeah, he adds, the horsepower will double–from 300 to 600.
