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.

GM-Isuzu joint venture assembles 1.5-millionth Duramax diesel

General Motors and Isuzu have officially stitched together 1.5 million Duramax 6.6-liter diesel engines. The joint venture between the two manufacturers started in 1998, and now the DMAX plant employs 517 workers in a 584,000 square-foot facility. GM introduced the Duramax turbo diesel engine to the US market for the 2001 model year, and it can be found trucks like the Chevrolet Silverado HD and GMC Sierra HD as well as the full-size Chevrolet Express and GMC Savana vans. In its current configuration, the engine yields 397 horsepower and 765 pound-feet of torque at just 1,600 rpm.
Of course, the big oil burner has plenty of tuning potential as well. As you may recall, a Duramax-powered truck recently set the land speed record for towing a vehicle at 142 miles per hour.
GM owns 60 percent of the joint venture, with Isuzu laying claim to the remaining 40 percent. The facility is located in Chicago. You can take a look at the brief press release below for more information on the milestone.

Junkyard Gem: 1990 Geo Storm GSi

General Motors created the Geo division in 1989, to sell rebadged Suzukis, Toyotas, and Isuzus in the United States. Most of these cars were snoresville econoboxes, but two Geo models got high-performance upgrades and GSi badging: the Prizm GSi (aka Toyota Corolla GT-S) and the Storm GSi (aka Isuzu Impulse). We saw a discarded Prizm GSi in this series last year, and now it's the Storm GSi's turn, with this '90 in a Phoenix self-service yard. The Storm GSi had a DOHC four-cylinder Isuzu engine making 130 horsepower, which was excellent for a 1990 car weighing a mere 2,392 pounds. The 2,174-pound 1990 Honda CRX Si had a mere 108 horsepower (and two seats), and it cost $11,130 versus the Storm GSi's just-slightly-higher $11,650 price tag. Of course, Isuzus never developed quite the reputation for reliability enjoyed by Hondas. This Isuzu notched up an impressive final mileage figure, though. The Storm sold for just the 1990 through 1993 model years, and the GSi still has a devoted following to this day. The interior is straight-up late-1980s-style Japanese-econobox stuff, with plenty of tough gray plastic. This content is hosted by a third party. To view it, please update your privacy preferences.
