Future Classic | 1990-1993 Geo Storm and Isuzu Impulse

You don't see a lot of Geo-branded cars on the road these days, despite the fact that the General Motors' captive-import brand was actually pretty successful for around a decade. Perhaps the most recognizable vehicle to roll into Geo showrooms was the Prizm, which basically amounted to a rebadged Toyota Corolla built in California (which means General Motors was competing against its own Chevy Cavalier in the compact sedan market). And then there were the Geo Metro sub-compact, known for years as the most fuel-efficient vehicle you could buy in the United States, and the spunky Geo Tracker SUV that carried on for several years wearing Chevrolet badges after Geo's demise. Those are all interesting vehicles, but for this article we're going to focus in on the sporty Storm model. Like the other Geo vehicles, the Storm was sort of a joint venture, in this case with Isuzu, the Japanese automaker best known for making SUVs and big commercial trucks. Back in the day, though, Isuzu had some legitimately intriguing little cars in its showrooms. The Storm was based heavily on the second-generation Isuzu Impulse (known as the Piazza in other markets). And, well, you see even fewer Isuzus on the road these days than Geos. MotorWeek | Retro Review: '90 Geo Storm GSi Why are the Geo Storm and Isuzu Impulse future classics? They may never actually be "classics" in the same way a Ford Mustang or Chevy Camaro may be, but they are still interesting cars. And for potential buyers of a certain age, memories of gawking at sleek-looking Geo Storms everywhere you looked mean the nostalgia factor is high. If nothing else, we're pretty sure a nicely kept Storm or Impulse would draw a certain crowd at a local car show. While the Storm was way more popular with American buyers in the 1990s, the rarity of the Impulse means it's probably the more desirable option if future collectibility is a factor. What is the ideal example of the Geo Storm or Isuzu Impulse? The most valuable version of the duo is surely the rare Isuzu Impulse RS (the silver car above) with all-wheel drive and a turbocharged 1.6-liter four-cylinder engine that spun out 160 horsepower and 150 pound-feet of torque. According to reports, only about 600 of these machines were sold in the States — complete with "Handling by Lotus" badging (General Motors held sizable stakes in both brands at the time) — which means they aren't very easy to find for sale.

Recharge Wrap-up: Minnesota first to require biodiesel, maglev in Israel, Toyota FCV in Aspen

A new Minnesota law that requires biodiesel blends goes into effect in just a few days, says KELO. Diesel drivers in Minnesota will be pumping soybeans into their tank beginning July 1. Every year, diesel will be sold as a B10 blend (ten percent biofuel) from April through August, and will scale back to a cold-hardy B5 blend from September through March. The biofuel largely comes from soybean crops grown within Minnesota, and the biodiesel industry pumps more than $900 million into the state economy every year. According to the National Biodiesel Board, using the B10 and B5 blends will reduce greenhouse gas emissions by 1,342,000,000 pounds every year. Minnesota is the first state to require diesel to be sold as a biofuel blend. In Japan, Isuzu Motors and Japanese biotech venture Euglena are teaming up to create biodiesel using algae, according to Bloomberg Businessweek. The goal is to create a new type of fuel that doesn't need to be mixed with light oil to be used in engines. "As long as we use light oil for diesel engines, emissions of carbon dioxide are inevitable," says Isuzu president Susumu Hosoi. Euglena has also been using algae to develop jet fuel with airline operator ANA Holdings. Isuzu and Euglena hope to have the new biodiesel developed by 2018. Aerial maglev transportation is coming to the campus of a defense contractor in Tel Aviv, Israel, Wired reports. The SkyTran personal rapid transit system uses small pods on an elevated magnetic track to move people from place to place. The pilot program will see SkyTran come to the corporate campus of Israel Aerospace Industries as soon as next year. The pods are hailed by phone, and carry passengers along the magnetic rail system at speeds of up to 44 miles per hour. The passive magnetic system levitates the pod attachment a centimeter above the rails, while a burst of electricity propels the pod forward. If the test at the campus goes well, SkyTran could spread to Tel Aviv at large, moving up to 12,000 people per track per hour with top speeds of 150 mph. The pre-production prototype of the Toyota FCV will make its North American debut at the 2014 Aspen Ideas Festival on Friday, June 27. The hydrogen car's finished exterior was revealed in Japan on Wednesday along with its nearly $70,000 price tag. It will go on sale in Japan by April of next year, and will come to Europe and California in the summer of 2015.

Porsche revives Pink Pig and Rothman's liveries for Le Mans

Long-time fans of Porsche, particularly its motorsports history, are in for a treat at this year's 24 Hours of Le Mans. The company took two of its 911 RSR race cars and gave each of them a famous color scheme from the past. The designs are part of the company's 70th anniversary celebration. The first and most unusual paint scheme is a modern rendition of the "Pink Pig." The design was used on a Porsche 917/20 in 1971. Just like the original, it's finished in a pale shade of pink with dotted lines marking out sections of the car. Each of these sections has a label for a different cut of meat from a pig. The other livery isn't as strange, but it's no less recognizable. It features a blue, red and gold color scheme of tobacco company Rothmans. Rothmans was a sponsor of many racing Porsches over the years, and the colors appeared on everything from Le Mans racers to the Paris-Dakar 959. This version on the 911 RSR notably lacks any tobacco branding or advertising. The two 911s with the retro colors will be competing alongside 8 additional 911s with more modern liveries. They will compete in the GTE classes at the 24 Hours of Le Mans. Related Video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.
