Motorweek looks back at the Pontiac Aztek

The Pontiac Aztek has earned a position as this generation's ultimate, automotive punchline. Even other execrable models like the Yugo or Mustang II probably get more respect these days just out of their sheer quirkiness, but the Aztek remains a joke. Fortify your mind for what's coming, though, because the much-maligned Pontiac might not be quite so atrocious, at least according to MotorWeek's latest Retro Review video. MotorWeek calls the Aztek, "GM's first true crossover vehicle," and it's amazing to think of the hated model as a progenitor of one of the most popular segments today. While admitting that the looks are polarizing, John Davis and company actually come away pleased with the Aztek's utility. They praise that there's a ton of room in the back, and the interior is packed with useful features like a removable cooler in the center console and radio controls in a cargo area. The show is even impressed with how the Pontiac drives and throws around accolades like "nimble" and "pleasant." After seeing the Aztek leading the pack on lists of the worst vehicles of all time for years, listening to it get such effusive praise is actually quite jarring. Could we all be so wrong? No, there's absolutely no debate that this is still a hideous automobile. However, MotorWeek asserts a complete reversal of the generally perceived wisdom about the early CUV. While unexpected, thinking about such an abhorred model in a different way is a cool experience. Check out the video for a different take on the Aztek.

Vitruvian Energy crowdfunding to make EEB, a trashy biofuel

When sewage is treated at a wastewater treatment facility, biosolids are the byproduct. After being separated from the water, biosolids are usually sent to a landfill or incinerated. That doesn't mean that they're without value, however. Vitruvian Energy has created a process to make a usable fuel out of this human waste product, and while the source is pretty gross, it is undeniably abundant, and the results are much cleaner. EEB can be made for less than $4 a gallon. In a process that Vitruvian Energy claims is energy efficient, biosolids are femented and introduced to a type of bacteria to create PHA plastic. Reacting the PHA with ethanol creates the ethyl-3-ethoxybutyrate (EEB) biofuel. Vitruvian says EEB can be blended up to 20 percent with gasoline or diesel without any engine modifications. This lowers the carbon footprint of the fuel it's blended into, and serves to oxygenate diesel, leading to fewer harmful emissions. EEB can also be made using other organic waste products, such as corn stover, rice straw and distillers grains. EEB can be made for less than $4 a gallon and isn't subject to the maddening market fluctuations and international politics of fossil fuels. Furthermore, EEB's carbon footprint is 70 percent less than that of fossil fuels. Vitruvian also sees potential for EEB to be used on its own to power vehicles or burned to produce electricity for the grid. So far, Vitruvian Energy has used grants from the California Energy Commission and National Science Foundation to develop EEB, and has tested the fuel in a Pontiac Solstice at Oak Ridge National Laboratory. Now, Vitruvian is wants to test EEB on a larger scale in the real world in order to prove EEB's viability to interested parties in the wastewater treatment industry. In an Indiegogo crowdfunding campaign, Vitruvian Energy hopes to raise $200,000 to build a prototype EEB production line and to run a test vehicle for a year on an EEB-diesel blend on the streets of Seattle. Donors can score some interesting perks such as shirts and bumper stickers that say "Get Clean with Poopaline." Learn more about EEB in the video and press release below.

Junkyard Gem: 1991 Pontiac Grand Am LE with Quad 4 Engine

GM introduced the N-Body compact platform with the Oldsmobile Calais and Pontiac Grand Am for the 1985 model year and continued building N-based cars through 1998. Most of these cars weren't interesting from an enthusiast standpoint, but a handful rolled off the assembly line with raucous DOHC Oldsmobile Quad 4 engines and manual transmissions, and those cars were plenty of fun. Here's a 1991 Grand Am with that rare setup, photographed in a self-service yard in California's Central Valley. The base engine in the 1991 Grand Am was the 110-horsepower, 2.5-liter pushrod Iron Duke, an engine that might have been fine on a Romanian tractor in 1953 but had no place on an American street car as the 21st century approached. Fortunately, GM started bolting the modern 2.3-liter DOHC Quad 4 engine into 1988 cars, and this was a proper four-cylinder. The Quad 4 ran a little rough and uncivilized, and it had its share of reliability problems, but you could rev the piss out of it and it made good power. In 1991, this engine was rated at 180 hp. That made this 2,592-pound sedan pretty quick. Unfortunately, the slushboxization of America had progressed with depressing rapidity during the 1980s, and by 1991 most Grand Am buyers — even the ones who opted for the Quad 4 — chose the automatic transmission. That didn't happen with this car, though — it boasts a rugged Getrag 5-speed instead of the happiness-amputating three-speed automatic. Yes, that's the kind of odometer reading you'd expect to see on an Accord or Maxima from this era. Someone loved this car and took care of it. Here we see an interesting mix of 1980s and 1990s car-radio technology. CD players in cars were still costly luxury items in 1991, seldom seen in affordable cars like the Grand Am, while 1980s-style slider-style EQ controls were on the way out. This Delco unit straddles both decades nicely. I seek out Quad 4-equipped cars during my junkyard travels, and I have photographed quite a few: this '89 Cutlass Calais, this '90 Cutlass Calais, this '90 Grand Am, this '91 Quad 442, this '93 Achieva SCX, and this '98 Cavalier Z24. It's a shame that Buick never put the Quad 4 in the Reatta, which was a fine car ruined by a somnolent and obsolete V6. The music in this ad is even more early-1990s than Crystal Pepsi.
