Isuzu: The Diesel Masters and the Lying Salesman

Isuzu is the unsung hero of the 90s SUV boom. Famous for the hilarious "Joe Isuzu" commercials and the rugged Trooper, they were masters of diesel engineering. While they left the US passenger car market in 2009, their legacy survives in the cult-classic VehiCROSS and the millions of GM trucks powered by Isuzu-designed Duramax engines.

"You Have My Word On It"

If you grew up in America in the 1980s, you know exactly who Joe Isuzu is. He was the pathological liar in the TV commercials who would claim the Isuzu Trooper could drive up Mount Everest or hit 300 mph, while the subtitle on the screen read "He's lying."

It was one of the most successful marketing campaigns in history. It put a relatively small Japanese truck manufacturer on the map. But behind the jokes was a serious company. Isuzu is, first and foremost, a commercial truck and diesel engine manufacturer. They build things to last.

The Boxy Legend: The Trooper

The Isuzu Trooper was the quintessential 90s SUV. It was a box. It had zero aerodynamics. It had "70/30" split rear barn doors. And it was brilliant.

It offered Land Rover capability for a fraction of the price. While the V6 engines were thirsty, the chassis was robust. Today, clean 1st and 2nd Gen Troopers are becoming sought-after overlanding rigs, appreciated for their simplicity and massive glass area (visibility is amazing).

The Weirdest SUV Ever: VehiCROSS

In the late 90s, Isuzu went crazy. They took a concept car and put it directly into production with almost no changes. The result was the VehiCROSS.

It looked like a moon buggy. It had two doors, fangs in the grille, and plastic cladding everywhere. It used sophisticated monotube shocks (with external heat reservoirs) usually found on race trucks. Only about 4,000 were sold in the US. At the time, people didn't get it. Today, it is a certified cult classic that turns more heads than a Lamborghini.

The GM Connection: Duramax

Isuzu stopped selling passenger cars in the US in 2009, but their heart is still beating in millions of American driveways. The legendary 6.6L Duramax Diesel V8 found in Chevrolet Silverado and GMC Sierra HD trucks? That was developed by a joint venture with Isuzu.

Isuzu also built the Geo Storm (a sporty coupe) and rebadged their SUVs as the Honda Passport and Acura SLX during the 90s. They were the "ghost writer" for half the industry.

Buying Advice: The Transmission Trap

If you are buying a used Isuzu Rodeo or Trooper (Automatic):

  • The 4L30E Transmission: This is the weak link. The GM-sourced 4-speed automatic transmission was barely strong enough for the heavy Trooper. If the fluid hasn't been changed religiously, it will fail. Check for slipping gears or delayed engagement.
  • Oil Consumption: The 3.5L V6 engines are known to burn oil. Check the dipstick. If it's dry, walk away.

Isuzu may only sell commercial box trucks in the US now, but the Trooper and VehiCROSS remain icons of a time when SUVs were honest, rugged, and a little bit weird.
